Abyss Stalkers
Abyss Stalkers Intercessor Marine.png
The Abyss Stalkers are a non-Codex compliant Space Marine Chapter in the 41st Millenium, created as a part of the Ultima Founding of Adeptus Astartes from the lineage of the feral Space Wolves. The Abyss Stalkers are masters of terror combat, attacking bit by bit, leaving destroyed corpses and hanging bodies on poles, slowly destroying enemy moral before releasing an all-out assault. Though they are a loyal Chapter, they are known to be more aggressive than most of their fellow chapters; attacking those they deem as heretics on sight, claiming it as an act of the Emperor's Executioners. It is unknown if this is one of the side effects of the Canis Helix. This chapter seems to have a strange obsession with Morkai and his uprising, because of the strange vision that their Chapter Master Vidar had and now every marine has to go through as a test.
Accentors
Accentors Tact Marine.png
The Accentors are a loyalist Codex-compliant Space Marine Successor Chapter created from the lineage of the legendary and feared Raven Guard during the 25th Founding, also called as the 'Bastion Founding', in the late 40st Millennium. They generally follows the Codex Astartes, though there are some differences due to their limited numbers and their prefered means of tactics and deployment of forces.
Adamant Wardens
Adamant Wardens Tactical Marine 2.png
The Adamant Wardens are a non-Codex compliant Space Marine Chapter in the 41st Millenium. They were created as a part of the 22nd Founding of Adeptus Astartes from uncertain lineage. The Adamant Warriors are siege masters, specialising in the breaking of sieges and assaults on static fortifications. Though a loyal Chapter, they have a reputation as being quite dour and secretive, much to the dismay of other Imperial organisations such as the Inquisition.
Adamantine Knights
Adamantine Knights Tactical Marine.png
The Adamantine Knights are a Loyalist Chapter of the Adeptus Astartes descended from the honoured Dark Angels and their Primarch Lion El'Johnson through the Angels of Absolution. They were founded during the 23rd "Sentinel" Founding, to replace a chapter of the Astartes Praeses that had been destroyed by the Forces of Chaos. They made their home on the feudal world of Lazaron, a planet culturally and geographically identical to the Dark Angels' long lost home world of Caliban.
Alpha Red Guardians
Alpha Red Guardians Intercessor.png
The Alpha Red Guardians are a Loyalist Space Marine Chapter of the Adeptus Astartes of the Imperium. Formed in the latter years of the Indomitus Crusade as a recent addition to the Chapters of the Adeptus Astartes, the Alpha Red Guardians has yet to establish itself as a respectable chapter. This is mostly due to the chapter they were formed from. Unlike most chapters, the Alpha Red Guardians are comprised entirely of Primaris Space Marines who have a disliking by the older generation of Astartes.
Angel's Litany
AL MK IV Artificer.png
Angel's Litany are a Loyalist semi Codex-compliant Successor Chapter created from the proud Sons of Sanguinius during the 4th Founding, shortly after the infamous War of the Beast.

The Chapter exclusively recruits its members from the Hive World Kandyra and the surrounding planets of Ragrin System. The Chapter is known for its usage of Azkaellon Pattern Bolts, a Bolt filled with an intense, energetic beam of heat in the tens of thousands of degrees Centigrade as well as the unusually large quantity of Sanguinary Guard armed with Power Glaives and Power Axes.
Angels Nemesis
Angels Nemesis Primaris Intercessor.png
The Angels Nemesis are a Loyalist Successor Chapter created from the proud and heroic lineage of the Blood Angels following the disastrous events of the Devastation of Baal at the hands of Great Devouer. This Chapter was created during the most recent Ultima Founding and is comprised mostly of newly revealed Primaris Space Marines. The Chapter's command cadre is made up of surviving veteran Firstborn from various remnants of now-extinct Blood Angels Successor Chapters that were wiped out during this lamentable campaign.

Angels of Annihilation

Pict-File Unavailable

The Angels of Annihilation are a Loyalist Space Marine Chapters formed during the 23rd 'Sentinel' Founding, otherwise known as the 'Sentinel Founding'. They are a successor chapter of the previously renegade chapter, the Manticores, and through them, trace their lineage to the noble Dark Angels and in turn makes them a part of the Unforgiven. Zealously loyal to the Emperor, the Angels of Annihilation's hatred towards the Fallen also spreads to other traitors, specifically other Chaos Space Marines. They believe that the only way to truly earn the Emperor's forgiveness is to wipe out all traitor Astartes from the galaxy.
Angels of Calth
AoC Tactical Marine.png
The Angels of Calth are a successor Chapter of the Ultramarines established in the immediate aftermath of the Horus Heresy. The original founders were composed primarily of natives from Calth who lost friends and family during the Betrayal at Calth. As such, they have adopted a particular grudge against the Word Bearers and World Eaters, and believe these groups must be opposed at all costs and by any means necessary. Exterminating entire worlds, utilizing daemons, leaving other Chapters to die--nothing is beyond what they are willing to do in their pursuit of vengeance. This vendetta was later extended to the Emperor's Children in response to Roboute Guilliman's mortal wounding by Fulgrim (although Guilliman's recent return has caused them to suffer something of an existential crisis,) and to a lesser extent now applies to all the forces of Chaos in general.
Angels of Salvation
Angels Salvation Tact Marine.png
The Angels of Salvation or Angeli na Spaseni in High Gothic, are a loyal 4th Founding Chapter of the Adeptus Astartes. Founded by legendary veterans of the Dark Angels. This Chapter shares many things with the honored first sons of the Emperor, including their highly stable gene-seed. In the years following their founding they fought hard to break free of the progenitor's shadow and forge their own legacy. They brought salvation to many a besieged imperial worlds and freed trillions from the oppression of deranged planetary governor's attempts to leave the Imperium. They are uncharacteristically forgiving for a member of the Unforgiven, believing that they should not bear the sins of their forebears, that their own actions and legends will bring them salvation. Evacuating populaces when necessary along with aiding in reconstruction is common practice when situations and time permit.
Angels of the Blade
Angels Blade Primaris Intercessor.png
The Angels of the Blade are a 4th Founding Loyalist Successor Chapter that descends from the lineage of the mysterious Dark Angels, and as such, are members of the collective of fellow Scions of the Lion Chapters known as the Unforgiven, with an Inner Circle that constantly hunt for the Fallen.
Angels Palatine
Angels Palatine Assault Marine.png
The Angels Palatine are a rather active, and somewhat well-known loyalist chapter of the Adeptus Astartes created during the ill-fated 21st Founding, the so-called 'Cursed' Founding, created from the proud lineage of the Blood Angels. This Chapter is located in a grouping of systems known as the Bright Stars, which are comprised of lush and mineral rich worlds within of the Segmentum Obscurus. Their whole reason for existence is to act as the defense force and arbiters of the Bright Stars, their main objective to defend the Stars from invasion through a semi-stable warp rift in the area known as the 'Malum', or 'The Evil', as well as reinforcements, should the Cadian System, and it's Cadian Gate, required aid. Most of their active duty is spent destroying minor Chaos incursions into their system, as the both the Malum and Eye of Terror (a giant warp-rift in realspace that leads to the hellish Realm of Chaos) resides in close proximity.
Angels Repentant

Pict-File Unavailable

The Angels Repentant are an Ultima Founding chapter of the Adeptus Astartes, formed by Commander Dante following the Devastation of Baal, where the veterans of the chapter served under the colors of the Blood Angels. They operate on the fringe of the Imperium Nihilus, currently stationed in the Urhus System. Known for tactical prowess, Astartes of the Angels Repentant prefer laying bolterfire at a distance, before closing the gap to rip their enemies to shreds. After battle, these battle-brothers are known to exercise their rage through the creation of art, and as such, the chapter's fortress-monastery is known to be lined with breathtaking paintings, sculptures, and many other masterpieces.
Angels Vehement
Angels Vehement Tact Marine.png
The Angels Vehement are a semi-Codex compliant, savage descendent of the Blood Angels. Created during an unknown founding this Chapter claims to have been a part of the ancient Second Founding, when the Space Marine Legions were torn asunder and reorganised in seperate Chapters. Despite the paucity of records, these claims are considered by most Imperial scholars as dubious at best. This Chapter is known to suffer a unique gene-flaw called the 'Angel Curse', which causes those who fall to the Black Rage to become mutated, daemonic figures. They have defended the Segmentum Obscurus from the denizens of the Halo Stars since M33.
Angels Vigilant
Angels Vigilant Pre-Heresy.png
The Angels Vigilant were a formerly loyalist Successor Chapter of the heroic Blood Angels, created during an Unknown Founding. After a xenos invasion decimated their isolated home sector, the Chapter made a deal with the Daemon Azazel, devoting themselves to the Ruinous Powers for the sake of salvation. They have re-painted their armour purple and dedicated themselves wholly to the Dark Gods. Eventually they were driven from their original homeworld and fled to the Eye of Terror. Now known as the Void Stalkers, this notorious Chaos Warband terrorize the Galaxy by launching multiple raids throughout the Materium.
(Excommunicate Traitoris)

Formerly declared Renegade (Excommunicate Traitoris) from 345.M41 to 013.M42, the Chapter has since been brought back into the Imperial fold after an investigation by Inquisitorial forces determined the original charges of Heresy against the Chapter proved to be unfounded, as well as the Chapter proving it's loyalty and lack of corruption in the Hyperion War that lasted from 999.M41 to 013.M42.
Ardent Shields
AS Mk VII Variant Veteran with Honors.png
The Ardent Shields are a Codex-compliant Successor Chapter create during the 20th Founding from the proud lineage of the venerable Ultramarines. The Ardent Shields are a Chapter whose founding was based off a need to add more numbers to the Adeptus Astartes in the Armageddon Sector while still abiding by the Codex Astartes. The Chapter was Founded near the end of M35, by a detachment of Ultramarines who had partook in the minor crusade known as the Salvation Crusade. These Astartes would form a much greater form of brotherhood with their Imperial Guard brothers which would come to define their very chapter in the centuries to come. They would soon be known for their immense sense of duty and skillfulness.
Argent Blades
Argent Blades Astartes.png
The Argent Blades are a 5th Founding Successor Chapter of the Ultramarines, tasked with the defense of the Kolleshian Sector in Segmentum Pacificus. Obsessed with the purity of their genes and their heritage, the Blades are rarely at full strength. The Argent Blades have become adept at utilizing doctrines laid out within the Codex Astartes. They rarely deploy more than a company to face a given threat, and have become experts at small tactical strikes. Using small and flexible forces to take down their foe as they attempt to repel the numerous threats that seek to destroy the sector.
Argent Eagles
Argent Eagles Primaris Intercessor.png
The Argent Eagles are a semi-Codex compliant Space Marine Chapter created during the 23rd 'Sentinel' Founding as a Sanguinius successor Chapter. Hailing from the World of Auroria within the Ultima Segmentum, the Argent Eagles specialize in close quarters combat and the use of jump packs. While they adhere to the Codex Astartes on some occasions they also follow their own set of rules called the Legisla Auroris. Having lost almost 1,000 Battle-Brothers during the Devastation of Baal, the Chapter now consists of mostly Primaris Space Marines with only the surviving Veterans of the elite First Company as well as the Chapter Master remaining Firstborn.
Argent Leviathans
Argent Leviathans Astartes.png
The Argent Leviathans are a semi-Codex compliant Loyalist Space Marine Chapter descended from an unknown parent Chapter that was founded during the 25th 'Bastion' Founding. The warriors of the Argent Leviathans revel in the glory of melee combat. The Argent Leviathans rarely use the Codex Astartes and instead utilise their own strategies and structure. The Chapter mainly recruits from their homeworld, the ocean world Caerule, however, they have recently been forced to recruit from other planets due to a shortage of Astartes.
The Ashen
Ashen Mk VI With Bolter.png
The Ashen are a Loyalist Space Marine chapter of the 23rd 'Sentinel' Founding. They are a suspected Successor Chapter of the Raven Guard. However, gene-seed analysis and records of the chapter is fragmented and missing vital sections. Due to this, the Adeptus Administratum dispute any official claim of Linagae. This Chapter is a Codex-compliant chapter that diverges in some aspects. They are a half-strength chapter, only mustering 500 fighting marines in 5 companies and they do not strictly adhere to the standard practice of Codex-proscribed markings. The Ashen are a little heard of chapter mostly adhering to their sectors of space tasked with fending off hostile incursions and pirate attacks on imperial assets and worlds.
Ashen Apostles
Ashen Apostles Grand Cleric.png
The Ashen Apostles are a Loyalist non-Codex compliant Space Marine chapter descended from an unknown parent Chapter founding during the 21st 'Cursed' Founding. The chapter earns the distrust of other chapters simply being born during the time of the Cursed founding, however, is not the only thing that earns them the distrust of other Astartes. The Apostles preference for diplomacy rather than all-out war which has made war-loving chapters such as the Space Wolves and Black Templars dislike the Apostles even more. When in and out of battle the Apostles are some of the most fanatical worshipers to the God-Emperor of all Astartes, because of this many of the worlds the Chapter has conquered are now highly religious due to the Apostles influences.
Ashen Crows
Ashen Crows Tact Marine.png
The Ashen Crows are a Loyalist Space Marine Chapter formed during the 19th Founding. The Ashen Crows claim to descend from the Primarch Corvus Corax and succession from the Imperial Talons Chapter. The Ashen Crows are a proud and isolated Chapter, claiming the proud heritage of their home world, Karit Tertium, with their goals aiming to strive and uphold it with honor and courage. The Chapter is known for operating with efficient skill against the Ork clans in Ork-infested space. It is rare for the Chapter itself to work with other Astartes.
Ashen Drakes
Ashen Drakes Astartes.png
The Ashen Drakes were a part of the 21st "Cursed" Founding. They proclaim to be scions of Vulkan and thrive to be worthy of his heritage. While they hailed from a Founding plagued by genetic deviancy and ill-luck, the Ashen Drakes had exhibited neither of those traits, until the formation of the Great Rift; when they were destroyed after a century long siege of their homeworld. However, their reputation remained that of a Cursed Chapter, which had make them more isolationists than other (alleged) Sons of Vulkan, for other Astartes shunned them and the Inquisition is ever vigilant. They were still one of the most humane Chapter in existence, living among their people and helping all they can, but they knen that only the most desperate of Imperial Commander would call for their help.
Ashen Knights
Ashen Knight template.png
The Ashen Knights are a Loyalist Codex-divergent Chapter of the Adeptus Astartes created during the Third Founding from the venerable Salamanders. Currently, they are a fleet-based chapter, and operate on the borders of Imperium-held space. Their primary specialties are in advanced search and recovery of artefacts, persons, and entities on Exterminatus-class Death Worlds.
Ash Scorpions
AS Mk VII With Bolter With Background.png
The Ash Scorpions are a Loyalist semi-Codex compliant Space Marine Chapter and 8th Founding Successors of the Imperial Fists Chapter. They are a proud Chapter whom try to adhere to the Codex Astartes wherever possible but have been known to disregard it if the situations warrants it. They stand as a bulwark against various threats that assail the Sigma Cluster, a volatile region located in the Ultima Segmentum, defending the worlds of the Imperium against xenos, heretic and Chaos forces.
Astral Arbiters

Pict-File Unavailable

The Astral Arbiters are a formerly Loyalist Space Marine Chapter created during an Unknown Founding and from unknown lineage. At some point, the Chapter was declared renegade by the High Lords of Terra and went rogue. They renamed themselves Blackvein's Corsairs - a band of vagabonds and greedy raiders - whose only recourse is currency. They show a marked hatred for chaos and view it as 'A fool's investment'.
(Traitoris Perdita)
Astral Consuls

Pict-File Unavailable

The Astral Consuls were a formerly Loyalist Space Marine Chapter created during the 20th Founding in late M35, from unknown lineage, as classified by the order of the Inquisition. Once noted for their fierce and meticulous fighting skills on the battlefield, this Chapter eventually fell into a tragic downfall of ill-fate, which led to the destruction of their beloved homeworld of Costov. Eventually they were declared renegades by the High Lords of Terra, and took to worshipping the Chaos God Slaanesh. Embracing the worship of the Pleasure God, they became the now infamous Chaos Warband known as the Forsworn, and now stalk Imperial space lanes, plundering and murdering as they see fit.
(Excommunicate Traitoris)
Astral Dragons
Astral Dragon Mk V Armor.png
The Astral Dragons is a Loyalist Space Marine Chapter of the Emperor's Adeptus Astartes whose roots date back to the dark days of the Horus Heresy. Extant records indicate this Chapter was created during the 3rd Founding in 001.M32. Officially, they are recognised as being created from the lineage of the proud and heroic Ultramarines. However, the truth of their actual heritage is a closely guarded secret, one known only to the senior members of the Chapter. Grim of temperament and terrifying in their unfettered anger, they have time and time again proven themselves to be utterly dedicated to the protection of the peoples of the Imperium.
Astral Fists
Astral Fist Mk V Variant.png
The Astral Fists is a Loyalist Codex-compliant Space Marine Chapter descended from the gene-seed of the unforgiving Iron Hands during the 23rd 'Sentinel' Founding that operates within the Segmentum Ultima. Following their inception, the newly created Astral Fists were deployed to the Tarsonis Sector in the Segmentum Ultima to fight off the xenos incursion occurring there. Eventually, they claimed the cleansed Tarsonis Sector as their own demesne. Like their progenitors, the Astral Fists Chapter maintain close ties and relations with the Mechanicum of Mars and are also more interested in their tactical success rather than their battlefield glory.
Astral Leviathans
Astral Leviathan Astartes.png
The Astral Leviathans is a loyalist Space Marine Chapter of the mysterious 13th Founding, the so-called 'Dark Founding', from an unknown parent chapter. The Astral Leviathans have seen extensive combat in the outer fringes of the Imperium combating Renegade planetary governors and militias, their majority of their campaigns being waged against humanity itself, this comes into the chapters very close ties with the Ordo Hereticus and the Ecclesiarch. Rituals and the imperial creed is a large part of the chapters life, they are some of the most zealous and fanatic of the Astartes, their armor and vehicles are heavily adorned with purity seals, scriptures, and litanies of battle.
Astral Paladins
Astral Paladins Primaris.png
The Astral Paladins are a Loyalist 3rd Founding Successor Chapter of the stoic Imperial Fists. The Astral Paladins formed with a focus on defensive tactics and long-range combat. The Astral Paladins were given a large amount of relic Mark III "Iron" pattern power armor upon their inception. The chapter took pride in their relic pattern battle-plate and revered it. Maintaining this precious gift from the Emperor was deemed extremely important. Due to the defensive static style of combat and a focus on - "No brother gets left behind" - the Astral Paladins rarely lose any of this relic armour and will often go to great lengths to recover these suits of armour from the fallen on the field of battle. Due to having much of it's founding armor, every Battle-Brother has at least a Mk III Helmet. The Astral Paladins have a close working relationship with the Astra Militarum and often spend a large amount of time fighting alongside these mortal Imperial forces.
Astral Reapers
Astral Reapers Sergeant.png
When the xenos, daemons, and heretics feel themselves victorious against mankind, then come the black hooded enforcers of the Emperor's will, as silent as the dead of night, to break both the enemy's morale and bodies, and they shall gloat nevermore. They are the Astral Reapers, sons of the Primarch Corvus Corax, born during the 3rd Founding. Having no home world to call their own and being a crusading chapter, these descendants of the Raven Guard wage stealth and guerrilla warfare against the enemies of mankind as the shadow-draped dagger of the Emperor's justice.
Astral Serpents
Astral Serpents Astartes.png
The Astral Serpents are a Loyalist Space Marine Chapter based in northern Ultima Segmentum at the edge of the galaxy. Being so isolated, they have very little contact with other imperial forces other than those which are in the Azeran Sector. Rarely has this Chapter been recorded in official Imperial records, and when they are the records are incredibly vague, and when young Inquisitors wanting advance in their position notice this, they head off to Viperae. Of course these Inquisitors find nothing and go back to Terra or to their masters after growing frustrated after listening to the chaplains and seers of the Serpents telling long drawn-out stories of their chapter's supposed ancient history.
Avengers of Tyran
Avengers Of Tyran Primaris.png
The Avengers of Tyran are a semi-Codex compliant Ultramarines Successor comprised entirely of Primaris Space Marines with a very unique history. Shortly before Hive Fleet Behemoth ravaged Tyran, a small fleet consisting of several Tyranian Regiments was sent to assist a local PDF. Upon returning, the fleet found that Tyran was barren, and that they were the only surviving Tyranian natives. Filled with anger, the survivors organised themselves into something similar to an Aeldari Craftworld; a fleet of ships containing the surviving population of Tyran. Eventually, Guilliman founded a Primaris chapter from the survivors, and they were quickly adopted into the fleet as a force to aid the pre-existing military force of the Tyranians. To this day, the Avengers of Tyran are combating the many Splinter Fleets of Behemoth.

Baleful Boars
Baleful Boars Assault Marine.png
The Baleful Boars is a very small and endangered Loyalist non-Codex compliant Space Marine Successor Chapter created from the lineage of the Blood Angels Space Marine Chapter during a unstated founding at the end of M37. It was created to counter the threat of the 7th Black Crusade in 811.M37, when Abaddon the Despoiler and his forces assaulted the Segmentum Obscurus. Since their inception, the Baleful Boars have writ a blood-soaked saga of fell deeds and numerous atrocities down the long millennia of their existence. The Chapter's detractors often point out that these ferocious Astartes appear every bit as savage and merciless as the heretical World Eaters Traitor Legion. Walking a precarious path between purity and damnation, only time will tell whether or not the numerous excesses committed by the Baleful Boars in the Emperor's name will be their downfall, and eventually they are declared renegades by the High Lords of Terra.
Baleful Paladins
Baleful Paladin.jpg
The Baleful Paladins are a Loyalist Successor Chapter descended from the esteemed and Mysterious Dark Angels of the Primarch Lion El'Jonson's bloodline. This Chapter is composed entirely of Primaris Space Marines, created during the most recent Ultima Founding by the recently awakened Primarch Roboute Guilliman. Operating in the Hexad Sub-Sector of the Milletatron Sector, the Baleful Paladins are highly active at prosecuting the wars of the Imperium against the myriad of enemies of Mankind. Like most of their allies of the Unforgiven Chapters, the Baleful Paladins are driven to prosecute the Dark Angels' secret war against The Fallen and are more than willing to answer their progenitors' call to war to achieve their objectives.
Battencian Heralds
Battencian Heralds Astartes Updated.png
The Battencian Heralds are a Loyalist 24th Founding Successor Chapter of the Adeptus Astartes whom are descended from the proud lineage of the First Founding Ultramarines Chapter. Despite their heritage as being Scions of Roboute Guilliman, one would assume this Chapter has a preference for shock assault and close-quarters tactics. But surprisingly, this is actually the Chapter's secondary focus, as they prefer to make use of mass-theatre fire and maneuver tactics. Despite their differences with their fellow Chapters of the Blood, the Battencian Heralds are a noble and proud Chapter. Despite their relative youth as far as Astartes Chapters go, their many hard fought battles and heroic victories have given them a reputation suitable for a Chapter much older than they are.
Bears of the Claw
Bears Claw Tactical Marine.png
The Bears of the Claw are a strange, but Loyalist Space Marine Chapter of the 20th Founding, created from unknown lineage. The Bears of the Claw are mostly known for their spirit, respect and determination, but are also known for being very devastating in combat. Unlike other Chapters, the Bears of the Claw did not possess the usual number of 1,000 battle-brothers, instead numbering around 700. For two millennia, the Bears fought with only seven companies, per Chapter tradition, refusing to reconstitute their three lost companies. But despite their smaller size, the Chapter's ferocity and stubbornness in the face of overwhelming odds, more than made up for their lack of numbers. It wasn't until the dawn of M42, and the advent of the newly revealed Primaris Space Marines, that the Chapter was finally able to reconstitute their long lost companies.
Black Devourers
Black Devourers Pre-Heresy.png
The Black Devourers are a former Loyalist Space Marine Chapter created during an Unknown Founding. Extant evidence points to this Chapter hailing from the proud lineage of the noble Rogal Dorn. Within only a few centuries, the chapter was discovered using Chaos-tainted artifacts by the Inquisition. The end result was the Chapter was declared 'Renegade', their homeworld destroyed and they were forced to flee, falling further into Chaos. Finding refuge within the hellish realm of the Eye of Terror, the Black Devourers became fully corrupted by the insidious touch of the Ruinous Powers, becoming a full-fledged Chaos Warband. To the shame of all Scions of Dorn, the fallen Black Devourers are descended from their lineage. They are one of the arch-foes of the Iron Blood Chapter, a feeling which is mutual. (Excommunicate Traitoris)
Black Knights
Black Knights Astartes.png
The Black Knights are a 9th Founding, fleet-based crusading Successor Chapter of the Dark Angels. They follow in the footsteps of the Lion and their Progenitors, and will not rest until every single Fallen Angel has been hunted down and brought back to the Rock, to be interrogated and granted extreme unction by the Interrogator-Chaplains of the Dark Angels. As a crusading Chapter, their doctrines, traditions, and organisation reflect their particular approach to prosecuting the Imperium's wars.
Blades of Dorn
Blades Dorn Mark IV.png
The Blades of Dorn are a proud Chapter descended from Imperial Fists lineage, created as a part of the 12th Founding during the tumultuous centuries of the Nova Terra Interregnum in M35. Since their inception this Chapter has earned the respect of their forebears through their courage, battle-prowess, and centuries of service in the Emperor's name. However, there once was a time that the Blades' loyalty was called into question, for it is to the Chapter's eternal shame that they are successors of the formerly loyalist Crusaders of Dorn, who were corrupted after entering the Eye of Terror in 321.M37, as part of the Imperial Abyssal Crusade, and reemerged centuries later in 112.M38, as the Chaos Warband known as the Brotherhood of Lethe.
Blades of Elysium
Blades Elysium Vet Astartes.png
The Blades of Elysium are a 4th Founding Chapter rumored to be descended from unknown gene-seed, but they are officially recognized by the Imperium at large as Ultramarines descendants. However, they are not on good terms with the Ultramarines or their Successors due to the fact that do not follow the dictates of the Codex Astartes. There is a mutual agreement that they will put aside this animosity for the greater good of the Imperium when possible. Only the current Hegemon knows the true story of their ancestry, told by an Inquisitorial Representative in the year of their ascension to the office. This Chapter is known to have an air of arrogance or superiority that sometimes to rub others the wrong way.
Blades of Morkai
Blades Morkai Primaris.png
The Blades of Morkai are a successor Chapter of the Space Wolves. They serve as the chamber militant for the Ordo Mercador, a minor Ordo of the Inquisition charged with being one of the few forms of oversight into the actions of Rogue Traders. Due to the demands of their charge, they are a fleet-based Chapter that specializes in void combat. The relatively small size of the Ordo Mercador and the vast amount of space their jurisdiction covers leaves the Ordo perpetually overextended, so Chapter Masters of the Blades of Morkai are also considered Ordo Mercador Inquisitors themselves in an effort to alleviate this.
Blades of Onyx
Blades Onyx Blackshield Astartes.png
The Blades of Onyx are a mysterious band of mercenary Astartes that have exiled themselves from the Imperium and sell their services to Rogue Traders and various xenos races. Their origins are unknown to the modern-era Imperium, however some Imperial scholars point to extant records and various eye-witness accounts, placing them throughout various events that have occurred throughout Imperial history for the last ten millennia. This would mean that their true origins more than likely harken back to the dark days of the Horus Heresy during the Age of Darkness.
(Fedelitas Tenebrae)
Blades of Redemption
Blades Redemption Astartes.png
The Blades of Redemption are a Loyalist Successor Chapter that hails from the proud lineage of the vaunted Ultramarines. Created during the 22nd Founding in the early decades of M37, there is little official information on this obscure Chapter in official Imperial records. The Chapter is renowned for its absolute adherence to the dictates of the Codex Astartes, the likes which is unheard of in many other Chapters -- including their genetic forebears.
Blades of the Lion
BoL Tactical Marine With Hood & Cloak.png
The Blades of the Lion are a 3rd Founding Loyalist Successor Chapter of the lauded and venerable Ebon Knights, whose lineage hails from the ancient Dark Angels Chapter. Their adopted homeworld, Havenfell, lies near the southern rim of the Imperium, and their mountain-top fortress-monastery takes the form of a mighty Imperial cathedral, it's great spire piercing the clouds. This Chapter has garnered a reputation as being honourable to their allies and implacable to their foes. Their valiant record of heroic deeds stretches back several millennia and is enviable by even some Chapters of more ancient provenance. Despite their laudable record however, like their forebears, the Blades of the Lion are also considered outcasts amongst the Dark Angels Successor Chapters - collectively known as the Unforgiven - for they were one of the few Chapters to stand by the actions of their genetic forebears, when they had the temerity to disobey the orders of the First Founding Dark Angels during the lamentable Crimson Blade Campaign. For their actions, the Blades have also been given an outcast status and are counted amongst those known as 'The Forgotten'.
Blades of the Wolf
Blades Wolf Tact Marine.png
The Blades of the Wolf are a formerly Loyalist Space Marine Chapter, created during an Unknown Founding. Though they claim lineage from the Dark Angels, in actuality their heritage hails from a that of the Luna Wolves. The reason for the chapter being deemed as heretics was due to their attempts at reversing-engineer xenos technology so to better combat the enemies of Mankind. However, the chapter did so without the consent of the Adeptus Mechanicus or the Ecclesiarchy, committing the unforgivable sin of Maletek Incarna. The chapter was deemed heretics around 990.M41, in which an Ecclesiarchy-backed fleet decimated the chapter's own fleet, leaving only the Battle-Barge known as The Unyielding Tide relatively intact. Though officially declared as 'Renegades' by the High Lords of Terra, the Blades of the Wolf continue to fight on behalf of the Emperor.
Blood Bearers
Blood Bearers Tact Marine.png
The Blood Bearers are a loyalist Space Marine Successor Chapter of the bloodline of Sanguinius, created during the dawning of M32 during the 3rd Founding. An extremely reclusive chapter, the Blood Bearers are stoutly bound to the Blood Angels, united by the blood of their Primarch Sanguinius that flows through their veins and ancient traditions that outsiders find difficult to understand. Their loyalty to the memory of their Primarch transcends all other duties and concerns. Being born from the Blood Angels' gene-seed, the Blood Bearers also carry the Flaw inherent in their gene-stock. The Blood Bearers do not deny their blood-lust, and in turn have learned to embrace it, making it a central part of their rituals. The Chapter thereby seems to have achieved an unparalleled level of restraint over their Flaw.
Blood Guard
Blood Guard MK IV Variant.png
The Blood Guard are a 11th Founding Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. Upon their inception this Chapter was assigned the task of searching out and eliminating the heretic, the traitor, and the xenos. They have a high success rate with less collateral damage. Seeking out and purgation of these threats is not all that they are capable of, and often, the Blood Guard is called upon to intervene in various Imperial crusades and conflicts.
Blood Hounds
Blood Hounds Pack Dog.png
The Blood Hounds are a Loyalist Space Marine Chapter created during an Unknown Founding sometime in M37, whose genetic lineage is believed to come from two notable First Founding Chapters (although not confirmed) - the Space Wolves and the Blood Angels. They were made as a standing force against the Khorne-worshiping berserkers and the feral Orks who invaded their planet long ago. The Blood Hounds are a violent and deranged Chapter, as most recruits are near feral and only listen to the "alpha-male" who leads these bloodthirsty battle-brothers. They prefer to use shock-and-awe tactics and lighting warfare being able to appear like a thunder storm or more related to a category five hurricane before disappearing like the wind. Due to their bellicose nature and unusual display of lightning-like, psychic abilities, they are kept under the ever-watchful eye of the Inquisition.
Blood Hunters
Blood Hunter.png
The Blood Hunters are a loyalist Space Marine Chapter formed during an unknown founding. While it is known they are descended from the Sanguinius, due to lost history, it is unknown which chapter they are successors of directly. Originating from the death world of Nionus, the Blood Hunters Chapter has trained their new recruits in the aggressive way of their people trained to hunt and eliminate their enemies with extreme brutality. Using aggressive stealth tactics to break down the enemy's defenses before fast striking waves of marines charge the enemy. They tend to favor close-quarters combat but are known to use ranged attacks to harass the enemy as well.
Blood Jaguars
Blood Jaguars Tact Marine.png
The Blood Jaguars are an extremely violent and savage Loyalist Successor Chapter created during an Unknown Founding sometime in M34 from the brutal and unforgiving Flesh Tearers, a Second Founding Successor Chapter of the heroic Blood Angels. Like their progenitors, the Blood Jaguars are known for their bloodthirsty nature in battle, ill-temper and bellicose nature. Though staunchly loyal to the Emperor and dedicated to their duty as protectors of the innocent, they are heavily afflicted by the genetic twin-flaws of their Primarch Sanguinius. The resulting brutality has led to their investigation on charges of heresy by the Inquisition on multiple occasions, though they have been cleared of suspicion at present. Like their genetic forebears, the Blood Jaguars are known for their bloodthirsty nature in battle, ill-temper and feared for the flaws of the Black Rage and Red Thirst that greatly affect them.
Blood Jaws
Blood Jaws Pre-Heresy Astartes 2.png
The Blood Jaws are a formerly Loyalist Chapter of Space Marines created during an Unknown Founding, and from uncertain lineage, in 013.M37. This bellicose and ferocious Chapter was created in order to stand as a bulwark against constant attacks in and around the Eye of Terror, from both the Forces of Chaos and various xenos threats. Unfortunately, within the first century of their creation the Chapter fell from the light of the Emperor, for unknown to them, their first Chapter Master had been corrupted by a Greater Daemon of Khorne. Following their ill-fated sojourn into the Eye of Terror, the Blood Jaws were slowly corrupted by the insidious touch of the Blood God. When they finally emerged, they had been transformed into a large Chaos Warband, wholly dedicated to slaughter and murder. Now they commit the most obscene levels of carnage wherever they go, in tribute to their brutal and bloody deity.

Blood Legion
Blood Legion Tact Marine.png
The Blood Legion are a Loyalist Space Marine Chapter, created from the lineage of Primarch Sanguinius of the Blood Angels. They are a bellicose and unforgiving Chapter that epitomises their Primarch's wrath against those that would dare transgress against the will of the Emperor of Mankind. Much of the Chapter's history was lost during their fight against the Tyranids of Hive Fleet Leviathan during the closing days of the 41st Millennium, when the xenos utterly destroyed their fortress-monastery, forcing the remnants of the chapter to abandon their sacred and ancient home, and becoming a fleet-based Chapter. Now the Blood Legion brings their unfettered wrath down upon those that would dare transgress against the realm of Mankind.
Blood of Vulkan
BoV Tact Marine.png
The Blood of Vulkan are a loyalist non-Codex compliant Space Marine Chapter of the Adeptus Astartes created during an Unknown Founding and of dubious origins. A bellicose and ferocious Chapter, these Astartes have developed unique abilities that enables them to be nigh unstoppable in close melee combat. These abilities include pyrokinetic breath that allows them to breathe fire and the ability to call upon the inherent rage of their Primarch, making them unstoppable berserkers.
Blood Reavers
Blood Reavers Intercessor.png
The Blood Reavers are a loyalist Codex compliant Space Marine Chapter of the bloodline of Guilliman, created during the 26th Founding in 738.M41. The Blood Reavers are known for their obsession with purity and ruthlessness in battling heretics, leaving little to no trace of their enemies' existence. Their chapter is organized around blood rites, and some Blood Reavers succumb to a sleep-inducing condition which exposes their minds to the warp and renders most of its victims mad or with severe psychosis.
Blood Scorpions
Blood Scorpions Astartes 1.png
The Blood Scorpions are a loyalist Space Marine Successor Chapter of the bloodline of Sanguinius, created during the 6th Founding, which occurred sometime during the latter years of M33. Extant evidence suggests that the Blood Scorpions were one of several Chapter founded in the wake notable event known as 'The Year of Ghosts'. Throughout their existence, the Blood Scorpions have garnered a brutal reputation for being savage and unrelenting fighters. This Chapter is also notoriously intolerant of all xenos, believing them to be a blight upon the galaxy. They adamantly believe that it is Mankind's manifest destiny to vanquish all the vile and wicked alien races, and to take their place as the rightful inheritors of the galaxy.
Blood Serpents
Blood Serpents Assault.png
The Blood Serpents were founded as part of the 12th Founding during M35 as a Successor Chapter to the venerable Blood Angels. Nearly a millennium after their Founding, they were beset by a series of disasters that saw the Chapter's numbers severely depleted, to the point where there were only three remaining battle-brothers. Despite talk of disbandment, the remaining survivors resolved to rebuild their nearly-extinct Chapter back to its former glory. The Chapter vanished, due to emergent warp storm activity, and was believed lost. However, in 584.M41, a new warp storm activity in the Chapter's home system appeared, and the Blood Serpents had a whole Chapter once again. However, due to the process utilised to recreate their sorely depleted numbers, they unexpectedly developed several idiosyncrasies unique to their Chapter. It remains to be seen, whether or not these genetic flaws will be the Chapter's undoing.
Blood Vultures
Blood Vultures Blood Brother.png
The Blood Vultures are a Loyalist Space Marine Chapter of the bloodline of Sanguinius, supposedly created during the mysterious 13th Founding, the so-called 'Dark Founding', which occurred sometime between M35 and M36. The Blood Vultures have garnered a dark reputation for being savage and unrelenting fighters. It is even believed by some that this powerful and robust Chapter is as mighty as their Progenitors. Although the Blood Vultures are unswervingly loyal to both the Emperor and the Imperium, their brutal deeds and sheer savagery and merciless ways when conducting their campaigns, have writ a bloody-handed and fell reputation across the annals of Imperial history. This has often caused them to be untrusted by various Imperial organisation as well as other Chapters of the Adeptus Astartes.
Bloodied Hunters
Bloodied Hunter Gífr Vargr.png
The Bloodied Hunters are a loyalist Space Marine Chapter created during the recent Ultima Founding during the closing years of M41 from the lineage of their mighty Primarch Leman Russ. This Chapter was created as one of several descendant Fenrisian Chapters from the line of Primarch Leman Russ, making up the unofficial collective known as the 'Sons of Russ' - to stand eternal vigil over the Imperial sectors that surround the Eye of Terror from the Forces of Chaos and encroaching xenos raiders. Like their namesake, the legendary wolf of Fenrisian mythology known as the Bloodied Hunter, this Chapter has garnered a fearful reputation as tireless pursuers and relentless hunters of the enemy - waiting patiently for the opportune moment to strike.
Bloodmoon Hunters
Bloodmoon Hunter Mk VII Tactical Marine.png
The Bloodmoon Hunters are a stalwart and dedicated non-codex compliant Loyalist Space Marine Chapter created during the 13th Founding, the so-called 'Dark Founding'. Little is known of this mysterious founding as there are no reliable records that indicate how many Chapters were conceived during this Founding or what became of them. Extant records indicate that the Bloodmoon Hunters were supposedly created during this Founding around the time a recorded prophecy foretold their inception. It is generally believed that the Adeptus Mechanicus might have played a role in the creation of this Chapter, as their inception occurred sometime in early M35, during the divisive and widespread doctrinal conflict known as the Moirae Schism. The Bloodmoon Hunters were known to maintain close ties with the Archmagos of the Cult Mechanicus as well, receiving a wide diversity of arms and weaponry, including power blades and relic weaponry of the finest quality and rare, advanced patterns of armoured vehicles and gunships.
Bloodsworn

Pict-File Unavailable

The Bloodsworn are a formerly Loyalist Space Marine Chapter created from unknown lineage during the 4th Founding in the middle-centuries of M32, following the near-disastrous War of the Beast. Tragically, this Chapter's service to the Emperor of Mankind was very brief, as after only a few decades, there were reports of this Chapter's overzealous prosecution in their duties, leaving formerly rebellious worlds as bloody abattoirs in the wake of their planetary assaults. After being declared renegades, this Chapter has embraced their status as outcast, launching periodic raids against Imperial merchant vessels and isolated worlds. They also work as mercenaries for hire for unscrupulous heretics.

Blue Flames
Blue Flames Assault Marine.png
The Blue Flames are a Codex-Divergent loyalist Chapter of the Adeptus Astartes, a 10th Founding successor of the proud Ultramarines bloodline. They reside in the Domus Caeli, an aerial Fortress-Monastery above the surface of Gertlysh, which in turn is (officially) a feral world in the Devotio Sector, more specifically Sub-Sector Heradea. These Astartes are notable for being the first of the forces in the tight-knit Devotio Sector to receive Belisarius Cawl's Primaris Marines, as well as their unusually close relationship with the Nerva Dynasty of Rogue Traders.
Blue Widows
Pre-Heresy Blue Widows Astartes.png
The Blue Widows are a formelry Loyalist Space Marine Chapter created during the ill-fated 21st Founding, the so-called 'Cursed Founding', sometime during M36. Like many of their fellow Chapters created during this time, they were plagued by aberrant gene-seed and extensive mutations. Deemed by the Inquisition as an abomination, the Imperium declared the stalwartly loyalist Chapter as renegades. The Chapter was forced to flee their home world of Draix, leaving the to its pre-ordained destruction by Exterminatus. Cast out from the light of the Imperium, the Chapter was forced to live the outskirts of known space within the mysterious region known as the Halo Stars. When the finally emerged centuries later, they were no longer the once-proud Blue Widows, for they had wholeheartedly pledged themnselves to the ruinous powers. Now known as the Fallen Widows, the vengeful Chaos Warband vowed to enact their vengeance upon those that cast them out and drove them from their former homeworld.

Bolts of Dorn
Bolts Dorn Firstborn.png
The Bolts of Dorn are semi Codex-compliant Successor Chapter created from the proud stoic and stalwart Imperial Fistss during the 4th Founding in the mid-500s.M32, following the end of the infamous War of the Beast. The Chapter was created as an expansion to rebuild many lost chapters of Imperial Fists lineage and other 2nd and 3rd Founding Successor Chapters. The Bolts of Dorn was also created to counter myriad threats from the Segmentum Ultima, be it the Forces of Chaos from the Maelstorm or the marauding Orks and the newly emerged Necrons and T'au Empire.
Bone Reapers
Bone Reapers Tactical Marine.png
The Bone Reapers are a Loyalist Successor Chapter created from unknown genetic lineage in late M40, during the 25th 'Bastion' Founding. Formerly known as the Revenant Lords, this young and bellicose Chapter soon garnered an infamous reputation for savage displays of barbarity and unsubstantiated rumours of bloody rituals. After several centuries of such behaviour, they were formally censured by the High Lords of Terra. The Chapter's true nature was brought to light in 910.M41, almost by accident, during the events of an Imperial campaign, when nearly their entire 1st Company manifested the symptoms of the Blood Angels' genetic curse, known as the Black Rage. Their shame revealed to all, they later met with the Blood Angels High Chaplain Astorath the Grim, who revealed the truth of the Chapter's genetic lineage. Embracing their heritage as one of the many Chapters of the Blood, the Revenant Lords renamed themselves the 'Bone Reapers'. Slowly accepting their progenitor's traditions and customs, the Chapter still struggle to curb the worst excesses of the Chapter's inherited warrior culture and blood practices.
Brazen Dragons
Brazen Dragons Tact Marine.png
The Brazen Dragons are a suspected Successor Chapter of the venerable Salamanders, created during the 17th Founding sometime during the latter years of M35. Since that bygone era, this Chapter has gone on to prove themselves as worthy servants of the Emperor. The walls of their fortress-monastery are lined with the lists of honours and campaigns they have served in. The warriors of the Brazen Dragons hold themselves to a high standard, seeing themselves as protectors of the Emperor’s people. This sense of duty cost them dearly during the trying times of the Great Rift and formation of the Dark Imperium, and now most of the chapter is made up of the new Primaris Space Marines.
Brazen Lions
Lion II Space Marine With Bolter.png
The Brazen Lions are a Loyalist Codex-divergent Space Marine Chapter created sometime between late-M35 and early-M36 during the mysterious 13th 'Dark' Founding from unknown genetic lineage. Since their inception, this Chapter has earned the respect of their fellow Adeptus Astartes and the Imperium at large, through their acts of courage, valour, battle-prowess and centuries of loyal service in the Emperor's name. However, there once was a time not long ago that the Lions' loyalty was called into question, for it is to the Chapter's eternal shame that they are successors of the formerly loyalist Astral Claws - a Chapter's whose name that is vilified within the Imperium, and is synonymous with infamy and treachery.
Bright Wardens
Celestial Knights Astartes.png
The Bright Wardens are a Dark Angels Successor Chapter based within the Ultima Segmentum close to the infamous warp anomaly known as the Maelstorm. Created during the 13th Founding, the so-called 'Dark Founding' sometime during M35, this chapter has continued the martial tradition of honour and chivalry as well as displaying a strong desire to slay the forces of the immaterium - both Traitor Astartes and Daemons alike. The Chapter is known to possess ancient Chivalry Pattern Bikes more than any other chapters.
Broken Wings
Broken Wings Marine.png
The Broken Wings were a semi Codex-compliant Chapter descended from the lineage of the heroic Blood Angels. They were an ancient and venerable Chapter who has valiantly served the Emperor of Mankind throughout the existence of the Imperium. Although officially their Founding is Unknown, they were already an existing Chapter of the old IX Legion at the time of the Great Crusade and Horus Heresy eras. Beset by grief and blaming themselves for not being present during the Siege of Terra to prevent the death of their beloved Primarch, the the mournful Chapter struck out into the stars so that they could avenge Sanguinius and "heal their wings". Alas, after millennia of faithful service, the Broken Wings fell on Baal Secundus where they sacrificed themselves to bring down a vast number of a massive Tyranid swarm of Hive Fleet Leviathan in 999.M41. To all who know of the Broken Wings' sacrifice, they regard it as the Chapter's redemption come at last.
Brotherhood of Embers
BoE MK IV Variant.png

The Brotherhood of Embers is generally concerned with the promulgation of the Imperial Cult and the preservation of what the Emperor sought to create, an empire of humanity across the stars. The Brotherhood achieves this through policing actions across the Segmentum Pacificus. When in combat, the Brotherhood puts the preservation of civilian life before all else. They see it as an important virtue to protect the lives of the Emperor of Mankind's most faithful subjects whenever and wherever possible, in order to replant the planet's society after a campaign has concluded.
Brotherhood of Shadows
Brotherhood Shadow Astartes.png
The Brotherhood of Shadows are a particularly infamous and darkly-famed Space Marine Chapter created during an Unknown Founding and from uncertain lineage. Their infamous reputation for the amount of violence they inflict upon their enemies is horrific, if exceptional. It is unknown when they were created, but extant Imperial records indicate that this mysterious Chapter first appeared sometime during mid-M35, during the tumultuous era of the Nova Terra Interregnum. The Astartes of the Brotherhood of Shadow are more vengeful executioners than noble warriors, walking a fine line between necessary evil and unchained horror. Since they first appeared, this ruthless Chapter has garnered a fell reputation for their merciless and brutal methods and are rightly feared by both their enemies and allies alike.
Brotherhood of the Midnight Sun
Bro Midnight Sun Keeh.png
The Brotherhood of the Midnight Sun are a loyalist Space Marine Chapter that was formed around the ill-fated 21st Founding, the so-called 'Cursed Founding', on the feral jungle planet of Xibalba. Though they claim lineage from the Blood Angels and the noble Primarch Sanguinius, their gene-seed has been tainted by the touch of the murderous Night Lords though the Chapter vehemently denies this. On their dangerous jungle home, the Brotherhood of the Midnight Sun continue to improve their ambush tactics believing that swift unexpected strikes can end conflicts quickly before they can get out of control. In truth, this method is to prevent their brutal and sadistic traits of their genetic forebearers from surfacing.
Brotherhood of the Sword

Bullfrogs
Bullfrogs Tact Marine.png
The Bullfrogs are a Space Marine Chapter succeeding from the Salamanders created during the ill-fortuned 21st 'Cursed' Founding. They were founded in order to support the Imperial forces in the Celestonic Sector. However, the Chapter soon found themselves afflicted with a mutation due to bungling ministrations of their Magos Biologis creators. This mutation, called the 'Toadbane's Curse', afflicts the Betcher's Gland organ, causing it to overproduce poison that secrete toxins over the Astrates' skin, creating a film of acidic mucous, that is lethal to the touch. Another unfortunate side-effect of this mutation is that these Astartes practically reek of death and decay, which has greatly affected their reputation, causing the local Imperial populace to distrust and avoid them.
Bulls of Retribution
BoR.png
The Bulls of Retribution are a Loyalist Successor Chapter descended from the lineage of the stoic and proud Imperial Fists, raised in the early decades of M38, during an Unknown Founding.

Caustic Cherubim Tact Marine.png
The Caustic Cherubim are a Loyalist Successor Chapter of the noble and venerable Blood Angels. Created during an Unknown Founding, this Chapter has gained some renown for their enjoyment of pure destruction and constant conflicts. Like their precursors, they keep the violent/angelic naming theme.
Caustic Reach
Caustic Reach Tactical Marine.png
The Caustic Reach are a small Adeptus Astartes Chapter created during the 21st Founding, the so-called 'Cursed Founding', from existing (presumably Raven Guard) gene-seed which was modified to counteract the high potency of Tyranid poisons and toxins these foul xenos commonly employed. Given the gene-seed the scientists managed to create a genetic resistance to the Tyranid poisons and toxins via unprecedented mutation which causes an overproduction of toxins and poisons within these Astartes bodies, which are then transferred to the Betcher's Glands within their mouths, causing them to 'drool' these poisons uncontrollably. This Chapter currently stands at approximately 350 Astartes, their forces severely depleted at the hands of Hive Fleet Kraken, though their exact numbers remain uncertain.
Celestial Heralds
Celestial Heralds Intercessor.png
The Celestial Heralds are a Loyalist Successor Space Marine Chapter created during the 15th Founding from the proud and noble lineage of the White Scars. The history and character of the Celestial Heralds is inseparable from the Huaguo Sub-Sector they call home and have defended for the past five millennia. The civilian government is run by a group known as the Eunuchs, once able administrators who have now devolved into almost comically nepotistic and corrupt bureaucrats. Compounding the issue, the chapter master of the Celestial Heralds is deeply involved with these Eunuchs and through personal loyalty, political blindness, and a complete loss of touch with the situation in his old age, has allowed his control of the situation to completely deteriorate. Reinforcements and Primaris Space Marine upgrades were sent to the sub-sector as soon as contact was made, but further assistance has since been put on hold. It is as yet unclear whether the Huaguo Sub-Sector should be considered fully loyal, or if measures should be implemented.
Celestial Shields
Nova Shields Tact Marine.png
The Celestial Shields are Loyalist Space Marine Chapter of unknown Founding and origins, though some suspect they are descendants of the venerable and unforgiving Iron Hands. This is due to their favoring advanced weaponry and heavy armour during battle. The chapter has gain a reputation of being unrelenting and merciless when on the battlefield, slowly pushing on without fear or remorse when gunning down the enemies of mankind.
Cerberus Chapter
Cerberus Chapter Intercessor 1st Bat.png
The Cerberus Chapter are a loyalist non-Codex compliant Chapter created during the recent Ultima Founding and comprised entirely of newly revealed Primaris Space Marines - the stage of evolution of the Adeptus Astartes. Primarily fleet-based, this aloof and mysterious Chapter keeps to themselves, preferring to wage their own private war against the enemies of Mankind. Rarely, does this Chapter fight alongside other forces of the Imperium, and on the rare occasions that they do, they prefer to keep their own counsel and wage their campaigns as they see fit, only reporting to Imperial command to inform them of their progress.
Chalice Heralds
Chalice Heralds Tact Marine.png
The Chalice Heralds are a Loyalist Successor Chapter of the proud and valiant Blood Angels created during Unknown Founding. Most of their history has been lost and their own records are either incomplete or destroyed. Because of this they guard their history and only tell those they trust, their origins. Despite their laudable history and numerous battle honours, there yet remains a shadow of the Blood Angels' genetic flaw that lingers ever about the Chalice Heralds. With a history of heroism and valour as laudable as some more venerable Chapters, it is easy to see why they are heralded far and wide across the Imperium as exemplars of the Great Angels' lineage. They have vanquished foes far and wide from Orks to Chaos Space Marines, and always upheld the honour of their Chapter, and founding Legion.
Champions of Mortis
Champions Mortis Tact Marine.png
The Champions of Mortis are an ancient, semi-Codex compliant Successor Chapter of Adeptus Astartes created during the 3rd Founding from an unknown sire. This Chapter is currently located in the southern fringe of the Imperium of Man, and they have devoted themselves to fanatically target and purge Heretic Astartes emerging from the Scourge Stars, especially those of the hated Death Guard Traitor Legion.
Chancellors of Genesis
Chancellor of Genesis Battleline.png
The Chancellors of Genesis are a nominally Loyalist semi-Codex-compliant Chapter created from unknown lineage during an Unknown Founding. They are an old and secretive Chapter. Not much is known about its background and the High Lords of Terra keep the purpose and lineage of the Chapter a well-kept secret.
Charnel Brethren
Charnel Brethren Astartes.png
The Charnel Brethren are an Astartes Chapter of Blood Angels descent, created during an Unknown Founding (but extant evidence points to either the 2nd or 3rd Founding). They are a slowly dying Chapter whose numbers have believed to have fallen below 300 Astartes. Though they are very loyal to the Emperor of Mankind their heavy affliction with the twin Flaws of their Primarch Sanguinius has led to their investigation on charges of heresy by the Inquisition. They have been cleared of suspicion at present, but many believe that that it is only a matter of time before they cease to exist. Like their Progenitors, the Charnel Brethren are known for their bloodthirsty nature in battle, bad temper and feared for the Flaws - the Black Rage and the Red Thirst - that they carry within their gene-seed. The Charnel Brethren follow the tactical organisation pioneered by the Blood Angels, favouring close combat over ranged warfare.
Children of Seth
Children Seth Tact Marine.png
Named after the bloody-handed lord of the Flesh Tearers from whom they are descended, the Children of Seth are a Chapter infamous for the murderously violent and destructive manner by which their wars are waged.

Since their inception, the Children of Seth have carved themselves deep into the annals of Imperial history, each page dripping with the blood of their foes.
Chiroptera Legion
Chiroptera Legion Tact Marine.png
The Chiroptera Legion are a mysterious and enigmatic Loyalist Adeptus Astartes Chapter created during an Unknown Founding and from uncertain descent, but it is believed to early. Imperial scholars speculate this Chapter to have possibly been created as early as the 2nd Founding, following the end of Great Scouring in 021.M31. They are inhuman monsters, vicious and violent beyond what is expected even of Astartes, their armour covered in macabre images of death and terror. These vicious Astartes have even been compared to the murderous Night Lords Traitor Legion, and the similarities between them have led many to claim that it is more than just coincidence, for unlike other Chapters that bring hope to worlds, the Chiroptera Legion does not come to liberate, they do not come to save - they come to bring judgement and to punish.
Chogorian Outriders
Chogorian Outrider Hellblaster.png
The Chogorian Outriders are an Ultima Founding Successor Chapter of the elusive White Scars, comprised entirely of newly revealed Primaris Space Marines. The Chogorian Outriders Chapter was founded in response to the creation of the Great Rift in 999.M41, serving within the legions of the Unnumbered Sons.
Claws of Arktos
Claws of Arktos Mk V Variant.png
Created from the ferocious Bears of the Claw, these bellicose and fierce Astartes were created during the 23rd Founding, the so-called 'Sentinel' Founding, as a part of a series of linked Foundings that took place during the latter part of the 37th Millennium to help replace the considerable losses suffered by the Adeptus Astartes in the preceding millennia. Along with several other Chapters, the Claws of Arktos were from the outset, conceived as a replacement Chapter that would spend its existence on continuous Crusade.
Cobalt Consuls
Cobalt Consuls Intercessor.png

Cobalt Leviathans
Cobalt Leviathans Primaris Intercessor.png
The Cobalt Leviathans are a Loyalist Space Marines Chapter founded during the 23rd 'Sentinel' Founding in M38 from the gene-seed of the fierce White Scars.

The Tribes (Companies) of the Cobalt Leviathans are always on the move, choosing instead to have their home world defended only by the Ocean Guard, Auna (serfs) and Togi (Neophytes) of the Chapter. Lead by a lone Vasa Ngaru, bearing the title of Lord of the Triumphrat, they are entrusted with the greatest responsibility and the hardest burden, to defend their hearth and home the fortress-monastery Pakari. That is not to say that the Tribes of the Cobalt Leviathans do not return home, for at the end of every campaign they return to tell their deeds through ritual chant preserving the oral tradition of the Chapter and of the homeworlds.
Cold Blooded
Cold Blood Tactical Mk VII.png
The Cold Blooded are a Loyalist Space Marine Chapter of the bloodline of Sanguinius, supposedly created during the mysterious 13th Founding, the so-called 'Dark Founding', which occurred sometime between M35 and M36. Like their predecessors, they stand aloof from the rest of the scions of Sanguinius and even from the Chapter from which they were spawned.
Conquistadors
Conquistadors Tact Marine.png
The Conquistadors (translated to High-Gothic as Conquerors) are a Successor Chapter created as a 23rd 'Sentinel' Founding of the Imperial Fists. While it is confirmed that their Primarch is indeed Rogal Dorn, it cannot be confirmed which Chapter they are descended from, with any certainty, however, many scholars believe they are descended from the Black Templars. The Conquistadors are a Chapter created with great ambition, intended to be a rapid-acting shock force and at the same time an exploratory colonizing force. Their primary goals are to give a rapid and forceful response to the conflicts that arise in the Segmentum Pacificus and to expand the borders of the empire by exploring and conquering new worlds in the name of the Emperor.
Corpse Wolves
Corpse Wolf Primaris-0.png
The Corpse Wolves are an Ultima Founding Successor Chapter created from the proud lineage of the feral Space Wolves.

They helped turn the tide in the notable Imperial campaign which came to be known as 'The War for Polaris's Star'. Located at the tip of the border between the newly designated Imperium Nihilus, or the 'Dark Imperium', which had gone dark without the beacon of the Astronomican, and the light Imperium.
Corrosive Thorns
Corrosive Thorns Astartes.png
The Corrosive Thorns are a 21st 'Cursed' Founding Chapter from the stock of the brave and stoic Iron Hands. This particular Chapter unlike its brethren have a low affinity for the Mechanicus rather being away from them as much as possible. Like many 21st Founding Chapters the Corrosive Thorns have a mutation in the Betcher's Gland that mutated into the pores of the skin leading to the sweat of the Astartes being heavily corrosive. Their combat speciality of the Chapter is Frontal Assault and Astarte Suppression especially towards other Iron Hands Successors.
Corvus Claws

Pict-File Unavailable

The Corvus Claws are a sneaky and deadly Loyalist Successor Chapter descended from the lineage of Corvus Corax lineage. Create during the 23rd 'Sentinel' Founding, this Chapter has become famed for jumping out of their aerial vehicles, mid-battle. They also specialise in covert missions and infiltrations. Another thing they are famed for, is their sense of humour. This makes them popular with some Chapter, others on the other hand find it annoying. Their most famous tactic is jumping out of a plane mid-flight. In this way they can surprise their enemy from above. They work in Kill-Teams and use the element of surprise. Even though they're a fleet-based Chapter they have a home world. It is there where they get their new recruits. Their Raven King resides on this planet, called Glavius. The fleets of the Claws travels around Galaxy. These Space Marines are deployed when Kill-Teams are needed.
Corvus Legion
Corvus Legion Astartes 2.png
The Corvus Legion are an Astartes Chapter that of Unknown Founding created from the line of Primarch Corvus Corax, and like their parent Chapter, they too, are renowned as cunning and patient hunters, adept at biding their time until the moment to strike is at hand and then attack with overwhelming force that leaves their foes with no chance of resisting. Their Founding is unknown, but many suspect that it was relatively early, perhaps as early as M32. Whenever their founding occurred, the Corvus Legion has served the Emperor with a cold, calculating and even intellectual temperament as well as possessing superb infiltration skills and skill at furious close-quarters engagements as the foes of Mankind are destroyed in a flurry of crackling lightning claws and the bark of bolters. Many a foe has considered himself safe, only to come face-to-face with the pale skin and jet black eyes of these ruthless Astartes.
Crimson Blades
Crimson Blades Primaris Intercessor.png
The Crimson Blades are Loyalist Successor Chapter of the mysterious Raven Guard, created during most recent Ultima Founding. Originally known as the Blades of Corax, the newly incepted Chapter was deployed as a part of the Imperial Indomitus Crusade in the wake of the tragic events of the 13th Black Crusade and the Fall of Cadia. Following their inception, the newly created Chapter nearly faced ultimate tragedy, when they discovered their newly assigned home world had become enthralled to the corrupting influence of the Ruinous Powers. Despite being massively outnumbered, the Astartes of the Blades of Corax stoically faced the heretic masses in a deadly siege. Emerging bloody but victorious, despite their extensive losses the Blades of Corax refused to be dettered. When the few survivors emerged from the ashes of their home world their battle-plate and weapons were so covered in the blood of the fallen, they henceforth referred to themselves as the Crimson Blades.
Crimson Dragoons
Crimson Dragoons Tact Marine.png
The Crimson Dragoons are a Loyalist Successor Chapter created during the 25th 'Bastion' Founding directly from the lineage of the zealous and fierce Black Templars Chapter, who themselves are descended directly from the proud and stoic Imperial Fists. Their capabilities with all forms of ranged weaponry can only be matched by their faith in the God-Emperor. Shielded by faith and armed with zeal, they strike down anyone who would dare oppose the Holiness of the one true ruler of Mankind.
Crimson Impalers
Crimson Impalers Tact Marine.png
The Crimson Impalers are a venerable loyalist Successor Chapter of the ancient and valiant Blood Angels created during the 3rd Founding at the dawn of M32. Down the millennia, this Chapter has garnered a reputation for their savage mien and use of unconventional tactics, and were eventually given an ultimatum by their Progenitors; lose all contact with their Founding Legion or change their ways. The Crimson Impalers chose to lose the support of Baal, and become a Chapter apart from their fellow Chapters of the Blood.
Crimson Prowlers
Crimson Prowlers Pale Hunter.png
The Crimson Prowlers are Successor Chapter that hails from the lineage of the mighty and powerful Space Wolves, created during the recent Ultima Founding in 999.M41. They were created as one of the first of many Successors, a whole line of descendant Fenrisian Chapters - the 'Sons of Russ' - capable of carving out a star empire the size of Ultramar. This was the vision: to be powerful enough to encircle the Eye of Terror completely, to prevent the Traitor Legions from daring to leave it ever again. The Crimson Prowlers, along with several other Primaris Successor Chapters, were created to help protect the Imperial sectors surrounding the Eye, and supporting Imperial worlds and the Inquisition as needed.
Crimson Raptors
CR Tactical Marine.png
The Crimson Raptors are a 4th Founding Successor Chapter of the famous Blood Angels. Like all sons of Sanguinius, the chapter suffers from the Black Rage and Red Thirst. Their history is marred by brutality and bloodshed, amplified by their twin curses. Now, the actively seek to redeem themselves and forget the sins of their past, hoping that with the new primaris they may establish themselves as an honorable scion of the Angel and no longer act as lonesome hermits.
Crimson Robes
Crimson Robes Tact Marine.png
The Crimson Robes were a Loyalist Successor Chapter of the stoic Imperial Fists, raised at the beginning of M32 during the 3rd Founding. Highly regarded for their siege capabilities and the arbiters of a number of impressive victories, this promising young Chapter was seemingly wiped out just over a millennia after its inception, but later returned to the Imperial fold, temporarily, nearly three millennia later. However, the Chapter's bad luck continued to dog them, as they had the misfortune to cross paths with a massive Ork WAAAGH!, only to be utterly annihilated.
Crimson Sentinels
Crimson Sentinel Assault Marine.png
The Crimson Sentinels are an ancient and laudible Successor Chapter whom believe themselves to have been created during the 2nd Founding shortly after the events of the Horus Heresy from the lineage of the noble Blood Angels. However, they do not appear in the list of Second Founding Chapters found in the Apocrypha of Skaros, the oldest-known surviving copy of the Codex Astartes, the veracity of their claim throws into question whether or not this Chapter is as ancient as they claim to be. Like all Successor Chapters created from gene-stock of the angelic Primarch Sanguinius, the Crimson Sentinels are also greatly affected by the affects of the twin genetic-curses of the Blood Angels' inherited Flaw. Although, unlike most of their fellow Chapters of the Host, they are more affected by the vampiric craving for blood, known as the Red Thirst, than they are by the ravages of the Black Rage. The Crimson Sentinels are known to suffer from this second flaw at a much reduced rate compared to the Blood Angels or their other Successor Chapters. The reason for this is unknown, however, many of their detractors whisper that perhaps the Chapter has bought this boon through malefic means.
Crimson Wardens
Crimson Wardens Fire Support Marine.png
The Crimson Wardens are a 7th Founding Successor Chapter of the Blood Angels. Inspired by their homeworld Anthas II, their culture is very knightly, and they value strength of will above all else. After being nearly wiped out by a Necron awakening, they were reinforced by the remains of a shattered Black Templars successor chapter, whose name is lost to the ages. This further influenced the Crimson Warden's culture to change their values to that of the Black Templars, though they aren't as religious.
Crimsonmarines
Crimsonmarine Mk VII Tactical.png
The Crimsonmarines are a Loyalist Space Marine Chapter and Successor of the Ultramarines Legion, first intended to be a Fleet-Based chapter. Believed to have been created as a part of the 5th Founding sometime in M33, this ancient and proud Chapter are lenient adherents of the Codex Astartes who consider the writ of the sacred text, penned by their blessed Primarch Roboute Guilliman, to be a divine guide of duty and honor rather than a law book. They are recorded to have made their own decisions and not have strayed too far from the Codex. Crimsonmarines are best known for their extreme hatred towards heretics also well known for a hybrid tactic of large arsenals of super weapons with various tortuous assault tactics.
Crystal Dragons
Crystal Dragons Astartes.png
The Crystal Dragons are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 25th 'Bastion' Founding, specifically for the purpose of supervising other chapters' penitent crusades. The Iron Hands lineage was chosen for their strong adherence to logical thought and reason over passion and feelings. In their short story, the Crystal Dragons have already accompanied over 20 of such crusades, treating those under their surveillance with cordiality yet cold severity to make sure that those Astartes atone for their past sins against the trust of the Emperor.

Dawn Guard
Dawn Guard Astartes.png
The Dawn Guard (sometimes known as the 'Cult of Dionysos') are a Renegade Chaos Chapter of Adeptus Astartes created during the ill-fated 21st Founding, the so-called 'Cursed Founding'. Unlike many renegade chapters, the Dawn Guard still cling to the precepts of the Codex Astartes and some members still continue worship of the Emperor, despite their renegade status. It is unknown what gene-father the Dawn Guard hail from, however it is known that a mutation in their gene-seed causes some members to suffer from a near insatiable greed. This flaw causes the chapter to make entire ships into "museum barges" that store mass amounts of knowledge, relics, and wildlife.
(Traitoris Perdita)
Dawn Guardians
Dawn Guardian Marine.png
The Dawn Guardians are a semi-Codex compliant Ultima Founding Successor Chapter descended from the proud lineage of the Ultramarines, specialising in liberating worlds lost in the calamity of the Great Rift as well working with the Historitors to reclaim vital knowledge from the most dangerous of warzones; recovering precious archives and destroying heretical texts with fire. Furthermore, they are known for their tendency to act as noble knights; charging into battle with swords raised to earn further glory for their Kingdom and Chapter.
Dawn Stalkers
Dawn Stalkers Mk VII White Revised.png
The Dawn Stalkers are a Chapter created during the 22nd Founding, a chapter born of the legacy of Rogal Dorn. While they publicly declare themselves as successors of the noble and proud Imperial Fists, they are in actuality sourced from the Crimson Fists, a secret known only to them and chapter father, along with relevant administratum officials. In combat and daily duties, the Dawn Stalkers place emphasis on the ability to withstand the punishment of body and soul alongside the care and protection of the Imperiums mortal population. For these reasons this chapter of Astartes are well versed in attrition-based warfare and rear-echelon/civilian protection duties.
Dawn's Wolves
Dawn's Wolves Alpha.png
The Dawn's Wolves are a rare successors of the Space Wolves Chapter, an oddity made possible by the creation of the Primaris Astartes. They have been created extremely recently, coming together as a Chapter only after the end of the Indomitus Crusade, from the ranks of the Unnumbered Sons. Since that time, the errant Chapter has made is best to defend the borders of the Imperium and bring the wrath of Leman Russ upon the enemies of Mankind. This origin explains why they are far less independent and more prone to cooperation with other Space Marines. The Dawn's Wolves make up a part of an unofficial collective comprised of a quadrumvirate of Space Wolves Successors known as the 'Sons of Russ'.
Death Angels
Death Angels Astartes 2.png
The Death Angels are a Successor Chapter of the venerable Blood Angels Space Marine Chapter. They were created during the 5th Founding sometime during the early centuries of M33. These Scions of Sanguinius were created at the express order of the High Lords of Terra in order to counter encroaching Forces of Chaos within the Tenadain Sector. The Death Angels tend to display a violent savage mien in battle, and have garnered a reputation as a bellicose and bloody-handed Chapter. As a Successor Chapter of the Blood Angels, they too, are greatly affected by the twin curses of the Red Thirst and the Black Rage. It is rumoured that they continue to reign down terrible destruction, wrought against friends and foes alike, yet the Death Angels still continue to faithfully serve the Emperor and their Primarch Sanguinius, despite their genetic afflictions.
Death Flowers
Death Flowers Primaris Intercessor.png
The Death Flowers are a Loyalist Successor Chapter of the Black Lotus Chapter which was created during the ill-fated 13th Founding, the so-called 'Cursed' Founding. The Death Flowers were created mostly of Primaris Space Marines during the recent Ultima Founding, after the original chapter was reduced to only one company. Such massive losses led to the creation of the newly reconstituted chapter. The chapter's predilection for guerrilla warfare and use of stealth tactics has led many Imperial scholars to suspect that they are successors of the Raven Guard Chapter. This Chapter was assigned with searching and destroying Necron tomb worlds.
Death Templars
Death Temp Reapers Bro.png
The Death Templars are a Loyalist Space Marine Chapter of the Third Founding that occurred in 021.M31, following the brutal and bloody years of the Great Scouring. An ancient and proud Chapter, the Death Templars are scions of the proud line of Rogal Dorn of the Imperial Fists Chapter. Aside from an unbreakable sense of honour and a history of unparalleled skill at arms, the Death Templars share little in common with their forebears' culture and traditions. Left to operate alone at the edge of the Imperium has bred within them an isolationist and fiercely independent streak that has seldom been embraced by outside command. Over time they have also gained a shadowed reputation for themselves with other Imperial authorities as well as fellow Adeptus Astartes, who view their seemingly unnatural obsession with death and strange mortuary traditions with suspicion.
Desert Crows
Desert Crows Tactical Marine 2.png
The Desert Crows, known formally as the 'Desertum Corvi', are a fierce and proud Successor Chapter of the mysterious Raven Guard that hails from the arid world of Geronimo V. The Astartes of this Chapter possess a well-deserved reputation as fierce combatants both in melee and from afar. As true inheritors of the Ravenlord, they are excellent ambush and guerrilla fighters, as well as beast-slayers at close-quarters combat, since each and every one of them has trained in knife fighting from infancy. So impressive are their skills with the knife that they have killed several notoriously deadly enemies of the Imperium with them. The desert crows also have a disproportionate amount of Scout, Assault, and Tactical Marines within their companies due to their combat doctrines.
Desert Hawks
Desert Hawk Mk VII Aquila Battle-Dmg.png
The Desert Hawks are a loyalist non-Codex compliant Successor Chapter created from the lineage of the ancient and heroic White Scars during the 8th Founding. It's a small and endangered Chapter with only three ordinary companies left after the Soul War - a hard won victory almost 300 years ago against the Chaos Lord Haman-Maat of Tzeentch and his daemons. This victory nearly destroyed the Chapter.
Destroyers of Worlds
DOW Scheme.png
The Destroyers of Worlds, or Kshatriya as they call themselves, are an 8th Founding White Scars Successor Chapter infamous for their excessive brutality and violence. This Chapter has garnered a reputation as being notorious and feared for their extremely brutal methods when fighting. Their reputation is such that when their name is spoken, those who know of them fall into a fearful silence as they pity the world that is about to suffer the wrath of the Destroyers of Worlds.
Diamond Knights
Diamond Knights Intercessor.png
The Diamond Knights are a recently created Ultima Founding Successor Chapter of the Ultramarines comprised entirely of newly revealed Primaris Space Marines. This chapter, unlike their predecessors and fellow successors, is only semi-adherent to the Codex Astartes. Despite being a young chapter they have fought many battles on behalf of the Imperium and are on constant crusade to defend Mankind from all who would do them harm.
Diamondbacks
Diamondbacks Tact Marine.png
The Diamondbacks are a loyalist Space Marine chapter created in M36 from the gene-seed of the stoic Imperial Fists during an unknown Founding. Hailing from the harsh desert world of Tejaz, this Chapter are notable adherents of the Codex Astartes. However, they have been noted for being unusually adept at their marksmanship skills, and have a higher than normal number of designated marksmen within their ranks. Despite such discrepancies, the Diamondbacks have continuously stood steadfast against the Forces of Chaos, standing eternal vigil against signs of threats to their home system and those Imperial worlds in surrounding systems. However, despite their long and glorious battle-record, this Chapter is held in suspicion by the Inquisition due to their unusual mastery at marksmanship and highly independent streak, and have on occasion, clashed with one another down the long millennia.
Dominators
Dominators Tact Marine.png
The Dominators are a loyalist Space Marine Chapter derived from gene-seed of the stoic and unforgiving Iron Hands Primarch Ferrus Manus. Since their inception, the Dominators have been known as a divergent Chapter that loosely follow that edicts of the Codex Astartes. Created during a now forgotten founding the Dominators have been known throughout the Imperium for their brutality in exterminating Chaos. Due to their seething hatred for Chaos, the Dominators will stop at nothing and will go to great lengths to extinguish the flames of sedition caused by those that follow the Eightfold path. Even though this Chapter possesses unwavering loyalty to the Emperor of Mankind, they often look down upon normal humans as weak sacks of flesh that are easily corrupted by Ruinous Powers. They believe in the incorruptible will of bionics and the machine.
Doom Hunters

Pict-File Unavailable

The Doom Hunters are a Loyalist Space Marine Chapter of unfortunate and mysterious origin, and very few outside of the chapter know it and live for very long after learning their secrets. Officially, this Chapter are well-hated traitors within the Imperium, classified as a renegade chapter who sided with the traitors by pure necessity for survival. In a "clever scheme" by the Inquisition, the Doom Hunters "feigned" betrayal at the behest of certain Inquisitorial parties in order to destroy the heretics from the inside. These parties remained the Chapter's only contacts and connection to the Imperium that they still secretly served. Mostly. However, now that their secret is revealed, there is no need for subterfuge. The Inquisition were in a rough patch politically and needed a win desperately. The Doom Hunters obliged, and their skill in dealing with the daemonic threat being close to the Grey Knights made the story semi-passable.
Doom Sentinels
Doom Sentinels Tact Marine.png
The Doom Sentinels are a venerable Loyalist Adeptus Astartes Chapter created during the 3rd Founding from the Salamanders. Known for their ruthlessness and determination, the Doom Sentinels have garnered a reputation of being absolutely merciless towards their enemies, or protecting the people of the Imperium. What information about their origins were lost during the 7th Black Crusade, also known as the 'Ghost War', when their homeworld of Quicksilver II was attacked by the dreaded Black Legion, though the world itself survived. Along with being one of the few loyalist chapters to still used chain-axes, the Doom Sentinels are noted to have enhanced strength surpassing what Space Marines are supposed to have, as well as greater durability. This mutation has been greatly used by the Doom Sentinels due to their chosen fighting style.
Dragon Guard
Dragon Guard Mk IV I.png
The Dragon Guard are an Astartes Chapter of Unknown Founding and descent, although there is evidence that points towards an early founding, perhaps even as early as the Second Founding. This Chapter hails from the mountainous world of Thel where great flying reptiles dominate the sky. These giants give their name to the Dragon Guard who descend on their enemies on great wings, their weapons fiery breath burning away the darkness.
Dragonkin
Dragonkin Tact Marine.png
A strange chapter shrouded is disturbing rumors and deeds, the Dragonkin were created during the ill-fated 21st 'Cursed' Founding from the ancient and venerable Salamanders. Whilst they would ordinarily be investigated and sanctioned by imperial authorities the Dragonkin appear to have powerful allies in the Holy Inquisition, most notably the Ordo Malleus. Though they appear to have avoided the uncontrollable mental and physical abnormalities of many of their brethren in the 21st Founding the chapter appears to have an almost palpable aura of death and ending about them.
Dragons Amaranthine
Dragons Amaranthine Vet Marine.png
The Dragons Amaranthine are among the few unacknowledged sons of the Primarch Vulkan. Believing themselves to be successors of the vaunted and venerated Salamanders chapter, the Dragons Amaranthine bear their heredity with pride, and keep true to many of the tenants espoused in their primogenitors Promethean cult. The Chapters home system of Jemenaius hosts three habitable worlds, on of which is an adeptus mechanicus forge world, which creates arms and armaments for the chapter and the region. This includes of production of Dreadnought Sarcophagi, which the Dragons possess in great numbers, these have become the saving grace of the chapter since suffering grievous casualties as a result of false information from an excommunicate Rogue Trader.
Dragons Sanguine
Dragons Sanguine Astartes.png
The Dragons Sanguine are a Successor Chapter of the vaunted and noble Blood Angels. Created in M35 during the turmoil at the start of the Nova Terra Interregnum the High Lords of Terra said a new founding must be created in order to pacify any rebellions that started to occur. The Dragons Sanguine were one of those chapters that arose during the 9th Founding. The Chapter was created in the Segmentum Tempestus in order to train for the time when they must be called to bring the Emperor's justice on those who left the Emperor's light. As their first mission the chapter participated in the Axon Crusade 50 years after they were created.
Dragons of Suzanoo
Dragons Suzanoo Battle-Brother.png
The Dragons of Suzanoo are a Loyalist Successor Chapter created from the wild and untamed lineage of the White Scars during the 23rd 'Sentinel' Founding. This Chapter stands eternal vigil over the planet of Suzanoo, an isolated feudal world located in the Eastern Fringe of the Ultima Segmentum. Like their genetic forebears, the Dragons of Suzanoo are an honourable and fierce Chapter. However, they adhere to a strict code that defines how they conduct themselves, both in war and in peace. The code of Bushio, known as 'The Way of the Warrior' emphasizes a life of virtue and integrity and is encapsulated in a warrior's honour, which is seen through an individual's actions and choices during their lives.
Drakken Harbingers
Drakken Harbingers Astartes.png
The Drakken Harbingers are an alleged (and unacknowledged) Successor Chapter of the ancient and heroic Salamanders. This Chapter was created during the 4th Founding sometime in the fifth century of M32, in the wake of the disastrous conflict known as the War of the Beast. Down the millennia, the Drakken Harbingers has garnered a reputation as a bellicose Chapter for they are highly active in seeking out the various foes of Mankind, most especially Chaos, in order to bring their righteous wrath down upon them. Due to their savage nature and drive to enact retribution against their foes they are rarely at full-strength. Since that bygone era, the Drakken Harbingers have proven themselves worthy inheritors of Vulkan and stalwart defenders of the Imperium of Man.
Dread Hands
Dread Hands Tact Marine.png
The Dread Hands are a Loyalist chapter of Space Marines that were created in the 4th Founding, - following the War of the Beast - this Chapter is descended from the stoic and unforgiving Iron Hands. Since the destruction of their oceanic homeworld of Liobos, the Dread Hands have become an entirely fleet-based chapter, sending the might of their naval forces wherever the High Lords of Terra command them.
Dread Knights
Dread Knights Brother-Knight.png
The Dread Knights are a Dark Angels Successor Chapter from the 21st Founding, known as the 'Cursed Founding'. To many of the scions of the Lion the Dread Knights are considered to be a rabid hunting animal or a blunt instrument, unleashed by Lord Azrael when word of a potential member of the Fallen reaches their ears, for when they are set upon the trail of one of the hated Angels the brother-templars of the Dread Knights are unrelenting, willing to rampage through entire systems to find and capture even a single one of their traitorous kin.
Dusk Crusaders
Dusk Crusaders Astartes.png
The Dusk Crusaders are a notorious Renegade Chapter who abandoned their duty for the power and pride only offered by the Dark Gods. Created during the 4th Founding in the mid-500s.M32, they were once proud servants of the Emperor, hailing from the proud lineage of the dutiful Rogal Dorn. But their overreaching pride saw them fall from grace and the light of the Emperor. Declared renegades, they renamed themselves the Dusk Born, and now serve the Ruinous Powers - fully devoted to spreading their heretical faith throughout the area surrounding the Maelstrom.

Dusk Howlers
Dusk Howlers Primaris.png
The Dusk Howlers, known as the Vlka Hrímherjar (translated as the 'Wolves of Hrímgard'), are an Ulitma Founding Successor Chapter comprised entirely of Primaris Space Marines, created from the lineage of the mighty Space Wolves. Their inception took place in the wake of Abaddon the Despoiler's 13th Black Crusade in 999.M41. The Dusk Howlers were created as a shock-assault force, to take back those worlds lost to the Traitor Legions in the wake of the formation of the galaxy-wide tear in reality known as the Great Rift. This Chapter is also known to make up part of the 'Sons of Russ', an unofficial collective comprised of several recently created Space Wolves Successor Chapters.
Dust Knights
Dust Raiders Tact Marine.png
The Dust Knights are an enigmatic Chapter of the Adeptus Astartes created during an unknown Founding and of uncertain origins, though most sources point to the Raven Guard. Mysterious, the Dust Knights rarely speak to other Imperial forces, let alone fight alongside them, coming and going as they please. Many Commanders, even fellow Space Marines, have noted how eerie these Adeptus Astartes are. Operating near the Fringe Worlds between the Segmentum Obscurus and Segmentum Ultima, the Dust Knights have struck against the Forces of Chaos, Tau, Tyranids and so forth, causing mayhem amongst their ranks. Despite their tactics and attitude, the Dust Knights value the lives of Imperial citizens and are willing to risk their lives to avoid civilian casualties.

Ebon Knights
Ebon Knight Veteran.png
The Ebon Knights are an ancient and proud Chapter whose origins are found in the chaotic centuries following the Horus Heresy. They were founded during the 2nd Founding as a Successor Chapter of the venerable Dark Angels Chapter. Their home world of Shadowmehr is located in the Ixaniad Sector in the Segmentum Obsucrus. Here, the insular Ebon Knights have stood silent vigil over their demesne, ever vigilant against encroachment by the Forces of Chaos or malevolent xenos for nearly eight millennia. For unknown reasons, the Ebon Knights are shunned by their Progenitors and fellow Unforgiven Chapters. The exact reason for this schism remains unknown to outsiders, but Imperial scholars have been able to speculate, tracing the most likely origin of this rift to the mid-32nd Millennium, during the so-called Crimson Blade Campaign, in the Scarus Sector. Despite their cold relations with their fellow Scions of the Lion, the Sable Knights have garnered a reputation for being honourable to their allies and implacable to their foes. This Chapter's extensive list of valiant deeds has even seen them come close to matching Chapters of more ancient provenance and heritage.
Ebony Dragons
Ebony Dragons Astartes.png
The Ebony Dragons are a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage, although it was sometime before M36. During the latter years of M36, the Chapter's homeworld of Charterous was engulfed by a massive warp storm and was eventually swallowed whole and pulled into the Immaterium. Declared lost, it was believed that the Ebony Dragons had disappeared for all time. But during the closing years of M41, with the destruction of Cadia and the formation of the galaxy spanning warp phenomena known as the Great Rift, the long lost world of Charterous was vomited back into reality. But the Ebony Dragons' long sojourn in the warp had transformed the battle-brothers of the Chapter, granting them powerful psychic abilities. The Ebony Dragons are often treated with open suspicion and hostility, for it was believed that no Space Marine Chapter could remain untouched by the predations of Chaos for so many millennia.
Ember Sharks
Ember Sharks Intercessor.png
The Ember Sharks are a Loyalist Space Marine Chapter created during an Unknown Founding, hailing from the lineage of the Primarch Corvus Corax. Since at least the middle centuries of M31, this bellicose Chapter has sailed the Outer Dark in the Segmentum Obscurus, silently watching for any threats that may come. In their mobile fortress-monastery, the Ark of the Furnace, a Chapter Barque, the Chapter continues their eternal vigil, silently watching and waiting for any threats that dare assails the realm of Mankind. That the Ember Sharks come from the gene-line of Corax is unquestioned, yet they are of brooding countenance, and utilize brutal terror tactics in order to cripple the foes of the Imperium before they are slaughtered by the vengeful marines of this Chapter.
Embers of Istvaan
Embers Istvaan Tact Marine.png
The Embers of Istvaan are an ancient Space Marine Chapter of unknown origins, created seven years after the end of the Horus Heresy, in the wake of the war of reciprocity known as the Great Scouring during the 2nd Founding. This Chapter was formed from survivors of the horrific tragedy known as the Dropsite Massacre of Istvaan V. Unfortunately, the Imperium has never been able to discern which legion they hail from, although many suspect they are more than likely descended from the lineage of the Salamanders Primarch Vulkan.
Emerald Vipers
Emerald Viper Primaris Intercessor.png
The Emerald Vipers Chapter is a Codex-compliant Successor Chapter created from the lineage of the Ultramarines during the recent Ultima Founding, consisting purely of Primaris Space Marines. The chapter mainly operates from the Death World of Viridium in the Ultima Segmentum on the Eastern Fringe, on the edge of the Ultramar sector bordering the territories of the T'au Empire and the Herzavar Sector. Led by their charismatic Chapter Master and former Veteran Sergeant of the Ultramarines 1st Company, Salvatus Augustus Severus, they serve as the eyes and ears of Ultramar, patrolling its vast borders for any incursion that might occur, be it traitor, xenos or daemons.
Emperor's Legion
Emp's Legion Legionnaire.png
The Emperor's Legion are an ancient and proud Loyalist Successor Chapter created from the lineage of the Primarch Roboute Guilliman. Created during an unknown founding, this venerable Chapter is believed to possible hail from the 2nd Founding, which occurred in 021.M31. However, there are no mentions of the Emperor's Legion in official Imperial records until at least the early decades of M32. Steeped in deep traditions and ancient practices, this Chapter resembles the culture of Old Earth's Romanii in a lot of similar ways. They are very organised and strict in their ways of war and have earned a reputation as merciless and fearless warriors in battle. Despite being a Successor Chapter of the Ultramarines, the Astartes of this Chapter are strict adherents of the worship of the Imperator as a God, but are not officially a part of the Ecclesiarchy.
Emperor's Liberators
Emp's Liberators Tact Marine.png
The Emperor's Liberators, known formally as the 'Imperatoris Liberatae', are a formerly loyalist Space Marine Chapter created from gene-seed of unknown origins during an Unknown Founding. During their creation Adeptus Mechanicus fleshcrafters made mistakes in the handling of the future chapter's gene-seed. Records of this chapter's founding were destroyed by said officials in order to save careers and the lives of those responsible for said mistakes. The chapter's history is one that tells of heroic beginnings, dutiful service, and the time of strife it endures to this day. A stinging irony that hangs over every battle-brother of the chapter is that despite their name and circumstances on paper, they are now more enslaved than ever. As the chapter continues to fight a never-ending war for its ideals and a war against fate itself, one question remains: What is the price of freedom?
Emperor's Own
Emperors Own Astartes.png
The Emperor's Own are a Loyalist Space Marine Chapter created during an Unknown Founding and are of uncertain origin. They were first listed in official Imperial records in early M36. The Emperor's Own do not count as one of the Hell Warders Chapters, having been based on Imperator Victor in Occidentis Auster of Sector Occident Prime since long before the opening of the twin warp rifts known as the Hellgates. The Emperor's Own primarily concern themselves with the defence of the sector form periodic attacks from Ork WAAAGH!s launched from Calverna, and as such, are not a part of the Hell Warders Chapters.
Emperor's Reapers
Emp's Reavers Tactical Marine.png
The Emperor's Reapers Space Marine Chapter is a loyalist crusading chapter of the Adeptus Astartes that loosely follows the dictates of the Codex Astartes. This ancient and venerable Chapter can supposedly trace their lineage back to the Second Founding, however, the validity of such claims has been difficult to verify due to the passage of millennia, lost records and human error. It is unknown exactly whose lineage this mysterious Chapter is actually descended from, but rumour and conjecture continues to abound amongst Imperial scholars. The Emperor's Reapers excel in close-quarters actions, often utilising a wide variety of close-range weapons, ranging from chain weapons, power weapons and even power scythes. This bygone (and often shunned weapon) is utilised exclusively by the chapter, one in which the Emperor's Reapers use as its primary weapon, above chain blades or other melee power weapons.
Emperor's Rifles
Emp's Rifles Standard Astartes.png
The Emperor's Rifles are a loyalist Space Marine Chapter of Unknown Founding and uncertain lineage. Hailing from the mountainous hive world of Parvat Obscurum, their origins are shrouded in mystery, as no records exist in Imperial databases. The only clue to this chapter's origins are passed down by oral tradition as folk tales and myths, which are perpetrated by men and Astartes alike. There are some indications in official Imperial records that this Chapter is possibly a rare Successor Chapter of the Raptors through the lineage of Primarch Corvus Corax.

Emperor's Trident Astartes.png
The Emperor's Trident are a mysterious and little-known Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. Not a lot of official information is known about this elusive chapter's past, but recovered records state that the Emperor's Trident has been active since at least M34 or M35. They are masters of void warfare and boarding operations. Since the formation of the Great Rift, the majority of the Chapter that was out on campaign, lost contact with the 1st Company and their Chapter Master. Despite this setback, the Emperor's Trident continues to stand resolute during Mankind's darkest hour.
Emperor's Wardens
Emperor's Wardens Mk VII Variant.png
The Emperor's Wardens are a loyalist not Codex-compliant Space Marines chapter of unknown Founding and progenitor who are known for their compassion towards the average humans of the Imperium and their desire to protect the defenceless. The chapter comes from the world of Archonia, a feudal world governed for millenia by nobles and protected by valourous knights, the Chevaliers of Archonia, who defend its people against the dangers of the galaxy and beyond. This order is very important within the chapter and the Emperor's Wardens are known for following the same traditions.
Epsilon Tempests
Epsilon Tempests Primaris.png
The Epsilon Tempest are a Successor Chapter of the vaunted Ultramarines. Founded during the recent Ultima Founding with the introduction of the Primaris Space Marines. The chapter itself was created with the reawakening of the Primaris filling its ranks. Sharing the gene-stock of the Ultramarines, they are heavily influenced by the dictates of the Codex Astartes, however, unlike other Codex-oriented Chapter, they still understand the importance and necessity to break these rules when needed by adapting to the situation. The Name Epsilon originates from the sector the fleets watches over, taking the Sectors name in honour of the necessary watch.
Eternal Paladins
Eternal Paladin Mk VII.png
The Eternal Paladins are a loyalist Chapter that is mostly Codex Astartes complaint, with a few notable deviations. They are a Successor Chapter of the Imperial Fists, founded during the early 38th Millennium as part of the 23rd Founding, the so-called 'Sentinel Founding'. Their homeworld is the feudal world Oighir, which is located in the Scead 10 System.

Eternity Invictors Intercessor.png
The Eternity Invictors are a Loyalist Successor Chapter descended from the proud lineage of the stoic Imperial Fists, created during the 25th Founding, the so-called 'Bastion Founding'. They currently operate as a fleet-based chapter due to the destruction of their home world Tradex IV, in 876.M40.
Eyes of Ferrus
EoF Primaris 1.png
The Eyes of Ferrus (known also as the 'Eyes of Iron') are a Loyalist Space Marine Chapter and are a confirmed successor of the Iron Hands. They are of the recent Ultima Founding in which their Chapter mostly consists primarily of Primaris Space Marines. This chapter suffers from a unique gene-seed flaw that some speculate to be pre-ordained by Divine will or by dark intervention, depending on who you ask.
Exalted Blades
Exalted Blades Tact Marine.png
The Exalted Blades are an 11th Founding Imperial Fists Successor Chapter that was born out of the Feast of Blades, the martial tournament held between the Sons of Rogal Dorn. When one of the Feasts became the target of a Chaos invasion the Imperial Fists and their successor Chapters of the day pooled their resources and formed a joint garrison to safeguard the region of space around which the Chaos incursion had originated. Years later, the many petitions made by the Chapter Masters of the line of Dorn were answered and a new Founding was sanctioned by the High Twelve. The surviving members of the joint garrison would go on to be among the founding members of the new Chapter, serving as both it's officers and it's veteran core. And so the Exalted Blades were born.
Exalted Seraphs
Exalted Seraphs Astartes 2.png
The Exalted Seraphs are a Loyalist Space Marine Chapter supposedly created from the lineage of the stoic Imperial Fists during an Unknown Founding, following the Reign of Blood sometime in the 36th Millennium. They are notable for being a bellicose and zealous Chapter, whom unlike other Space Marine Chapters, are notably strict adherents of the Imperial Cult, believing in the Emperor's divinity and humanity's manifest destiny to dominate the stars. Though they initially believed they were descended from the lineage of the Imperial Fists, it was recently revealed that they are actually descended from the lineage of the Dark Angels. For reasons unknown they are looked upon with great acrimony and distrust by the Chapters of the Unforgiven.
Excarnators
Exarnators Intercessor.png
The Excarnators are an Ultima Founding Successor Chapter of the proud and merciless Iron Hands. This stalwart Chapter is entirely comprised of newly revealed Primaris Space Marines. The Excarnators exist to defeat the heaviest armor employed by various xenos and the Traitor Legions. They are responsible for reinforcing the Jericho Reach and Imperial Knights along the Eastern Fringe. Based on their natural resistances to plague and illness, Inquisitors of the Ordo Sepultrum and Ordo Malleus choose to closely partner with the Chapter to combat the spread of pestilence by Nurgle and banish the daemons spawned as a result its presence.
Exercitus Imperialis
Exercitus Imperialis Intercessor.png
The Exercitus Imperialis, commonly known by their Low Gothic name, the 'Imperial Host', are a 26th Founding Successor Chapter, created from the lineage of the stalwart and heroic Ultramarines. Adopting combat styles perfected by their predecessors of the Silver Centurions, they excel in phalanx infantry formations covered with overlapping fields of fire from their tactical and devastator squads with armoured support from their formations of Astartes Battle Tanks. They have defended the western borders of Segmentum Ultima since their inception, becoming experts in breaching operations and open field warfare in the process.

Falcon's Claws
Falcon's Claws Tact Marine 2.png
The Falcon's Claws are an ancient and ferocious 3rd Founding Successor Chapter created from the lineage of the proud and savage lineage of the White Scars. Created in the wake of the Great Scouring, the Chapter took their namesake from the V Legion's ancient auxiliary order known as The Burgediin Sarhvu or 'Falcon's Claws', a small Order composed of veteran warriors that excelled as hunters and forward scouts on the battlefield, well known for their expertise in survival and the quiet elimination of enemy commanders. When this Chapter was formed at the dawn of M32, they carried on the traditions of their order, continuing to stalk the battlefields across various warzones, delivering swift and brutal death to those that would dare oppose Mankind's manifest destiny as the rightful inheritors of the galaxy.
Fangs of Fenrir
Fangs Fenrir Intercessor.png
The Fangs of Fenrir are a loyalist Successor Chapter whom descends from the wild and untameable lineage of the Space Wolves. The Chapter was founded during the Ultima Founding and is comprised completely of Primaris Space Marines. They are known for their savageness and absolute fury in close combat. They're at their very best when battling large armies in dense terrain. There they have the possibility to single out a target and destroy it. Being Sons of Russ, they excel at melee combat, but they still are respectable long-range combatants that can fight from a distance, because they are extremely precise with their bolters. Coming from the icy planet of Middenheim, they can resist the cold and can survive at temperatures that would kill an ordinary human. In battle, they can often be seen using wolves and Vargs as mounts to outrun their foes.
Fatebinders of Tyr
Fatebinders Astartes.png
The Fatebinders of Tyr, known also as the Fatebinders, are a loyalist Space Marine Chapter created during an Unknown Founding from the lineage of the stoic and stalwart Imperial Fists. Much of the lost records of their past history is passed down orally from brother to brother, down the millennia. The Fatebinders' main mission is to cull and recover lost knowledge and defend their Chapter homeworld of Tyr and the systems surrounding it.
Ferrus' Children
Ferrus' Children.png
Ferrus' Children are a Codex Astartes-compliant Loyalist Successor Chapter of the unforgiving Red Talons, whom themselves are descended from the lineage of their unforgiving and stoic Primarch Ferrus Manus. Active since the middle of the 35th Millenium, this fleet-based fighting force is known for its ferocity and stubordness in battle, never fleeing combat in the name of their fallen primarch. They usually lend their forces to Astra Militarum's regiments, adding their stupendous firepower and highly armored vehicles to the Imperial Guard's huge numbers in order to deliver quick, efficient defeat to His enemies.
Fists of the Gorgon
Fists Gorgon Astartes.png
The Fists of the Gorgon are a Loyalist Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. They were created in the latter part of M37, a tumultuous period in Imperial history, where the Adeptus Astartes suffered the loss of dozens of Chapters through attrition or corruption by the Ruinous Powers. The Fists of the Gorgon were one of several Chapters created as a part of the 23rd 'Sentinel' Founding, and were intended to help shore up the losses and repair the power of the Adeptus Astartes. Since that bygone era, the Fists of the Gorgon have continued to stand sentinel over the Siovis System, but have answered the call of the High Lords of Terra, when called upon.
Flesh Rippers
Flesh Rippers Astartes.png
The Flesh Rippers are an infamous Loyalist Chapter of unknown origin and Founding, said to be created in the early years of M34, though there is some conflicting evidence on this in the Imperial records, with some reference to the Chapter existing as early as M32. This Chapter is suspected, due to their pale skin, to be descended from the Raven Guard but they are known to be extremely stubborn and have shown signs of paranoia and they are noted to fall into a berserk fury during battle similar to Blood Angels further clouding their origins. Others have claimed a link to the World Eaters Traitor Legion. Whatever their origins, the Flesh Rippers are bloody handed monsters - vicious and violent beyond what is expected even of Astartes. They are Loyalists of the Emperor of Mankind though the significant evidence of major genetic flaws has led to their investigation on charges of heresy by the Inquisition.
Forge Templars
FT Black Armor Template White Emblems.png
The Forge Templars are an unacknowledged Salamanders Successor Chapter created during the 4th Founding in the middles centuries of M32 in the wake of the near-disastrous War of the Beast. In the course of their long and exemplar history, the Forge Templars showed all the qualities of the sons of Vulkan, along with a penchant for flamers and melta weapons. The chapter suffered heavy losses during the 13th Black Crusade and the subsequent Noctis Aeterna, including great part of their honoured Dreadnoughts. Thus the new Primaris reinforcements were warmly accepted by the Forge Templars.
Frost Lions
Frost Lions Intercessor.png
The Frost Lions are a Codex-Divergent chapter consisting entirely of Primaris Space Marines, created during the recent Ultima Founding at the end of M41. Born from the gene-seed of the stoic Imperial Fists - sons of the Primarch Rogal Dorn - the Frost Lions hunt the traitors and heretics from ten millennia ago to bring final vengeance.

The Garuda Legion are loyalist Codex-compliant Adeptus Astartes Chapter created during an Unknown Founding. There are no records trace the chapter's lineage of their Primarch, with the exception of a lone marking of a raven glyph on the gene-seed case. The Garuda Legion was created as a commendation from the High Lords of Terra to combat against Drukhari raids and Ork marauders as well as Chaos Cultist uprising across Segmentum Tempestus, specifically the Indonesyc Sector.
Gatekeepers
Gatekeepers Astartes.png
The Gatekeepers are an Imperial Fists Successor Chapter created during the 4th Founding following the near-disastrous War of the Beast in the middle centuries of M32. This Chapter is also the de facto leader of the Astartes Chapters that make up the Hell Warders - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the Hellgates - dual warp storms located in the Segmentum Solar which are uncomfortably close to Holy Terra.
Gershwin Company
Gershwin Co Heretic Astartes.png
The Gershwin Company is a strange and eccentric Renegade Space Marine Chapter founded by Pierrepont Gershwin. They were created during an Unknown Founding and of uncertain origin. Composed of three divisions, they are dedicated to unity among races, defense of the innocent, and peace through diplomacy. Their greatest belief is in the "Brotherhood of Life", meaning that all thinking creatures are linked, and that the best way to defeat an enemy is to make them your friend. They are also known for their unusual tactics on the battlefield, performing elaborate synchronized dances and singing in harmony to intimidate or confuse the enemy. The complete doctrine of the Company is found in Gershwin's Codex Musica, which outlines the basis of the Company.

Gilded Hammers
Gilded Hammers Tact Marine 7th Co.png
The Gilded Hammers are a Loyalist Chapter of Unknown Founding and unknown origin. An intentional flaw in their gene-seed means that their sense of hearing is greatly increased but they can not speak above a whisper. They venerate the Emperor and the nine Loyalist Primarchs as a pantheon of gods, with each company venerates one above the others. The unknowns of the Gilded Hammers are all done on purpose with many of their ancient relics having whatever previous decoration they once possessed, scoured before they first appeared. This Chapter specialises in void warfare, boarding actions, and heavy armored assaults. The Gilded Hammers are known to have a very close relationship with the Ordo Xenos and work for them often and to great effect.
Gloam Strikers
Brother Ekidius Smasch 2.png
The Gloam Strikers are a specialist Chapter created during the 25th Founding, circa 405.M39. Though they hail from unknown lineage, they believe themselves to be a Successor Chapter of the mysterious Sons of Antaeus, who were created during the 21st Founding, the so-called 'Cursed' Founding. Like their supposed genetic forebears, the Gloam Strikers are unusually large and robust physical specimens, even amongst their already superhuman kind - capable of surviving wounds and physical injuries that would kill even other Astartes. In battle, they deploy as a small strike force Chapter that specialises in extended period assault operations, harsh environmental warfare and combat field engineering.
Golden Knights
Golden Knight Mk III Variant Armour.png
The Golden Knights are an ancient Space Marine Chapter of Unknown Founding and unknown origin, though the paucity of surviving records point to this Chapter being Founded soon after the events of the Horus Heresy. However, much of their earlier history, from their inception onwards through M37, has been lost. During M38, a massive Chaos incursion of their Chapter homeworld, Zinthreon II, located in the Segmentum Obscurus, resulted in the destruction of most of the Chapter's records pertaining to their origins. The Chapter strays greatly from the dictates of the Codex Astartes and have nearly been declared traitors for several charges of 'legion building' after several cases where the Chapter's numbers exceeded the maximum-allowable 1,000 battle-brothers. These charges would have led the chapter to being declared Excommunicate Traitoris, if it were not for the chapter's creation of 'The Weeding' wars.
Golden Lions
Golden Lions Tact Marine.png
The Golden Lions are a Loyalist Codex-divergent Chapter create during an Unknown Founding from the prestigious lineage of the stoic and stalwart Imperial Fists. Since their inception, this Chapter has suffered its fair share of tragedy, including losing almost all of their history. They also suffered the dual ignominy of having one company turning to Chaos and another company splitting away as renegades, forming their own separate Chapter known as the Red Swords. Due to these separate incidents, they have been kept under tight scrutiny by an Inquisitor of the Ordo Hereticus. Since that time, they have only taken part in campaigns in their own home sector, standing sentinel against the continuous threats from both xenos and heretic forces, which assails this region of space with great frequency.
Golden Seraphs
Ordo Angelus Tactical Marine.png
The Golden Seraphs is an ancient Successor Chapter that hails from the proud and noble lineage of the angelic Primarch Sanguinius. Created during the 2nd Founding in 021.M31, following the end the Great Scouring, the great war of reciprocity against the vile Traitor Legions that occurred following the bloody galaxy-wide conflict known as the Horus Heresy. The Golden Seraphs inherited their Progenitor's pride on their ability to meet the foe head-on, no matter the odds. During this tumultuous time in Imperial history, those Chapters created during this particular Founding quickly garnered a reputation as savage and merciless Astartes, who willingly struck fear into the Imperial populace to scare them into compliance.
Golden Torches
Golden Torches Mk VII Aquila.png
The Golden Torches are a venerable 3rd Founding Chapter. Their origins unknown, but some say they show resemblance in terms of beliefs to that of the burning righteous Salamanders. Furthermore, the Golden Torches are well known for their master-crafted weapons and armour, and high number of vehicles, just like the sons of Vulkan, further pushing the idea of their origins.
Gorgons of Extinction
Gorgon intercessor background2.png
The Gorgons of Extinction are a Loyalist Successor chapter created during the 4th Founding sometime in the mid 500s.M32, descended from the gene-seed stock of the stoic and unforgiving Iron Hands' Primarch Ferrus Manus.
Graven Skulls
Graven Skulls Tactical Marine 2.png
The Graven Skulls are recognized as a Loyalist Space Marine Chapter of unknown Founding and origin. These frightful and cryptic marines are a more horrifying, nightmarish force of power armour-clad spectres, rather than the mythic figures that the Imperium idolises as the Emperor's Angels of Death. Mystery and suspicion attach themselves to these dour and macabre warriors regardless of their true loyalties or intentions, and while they nominally serve on behalf of the Imperium, they prefer to operate independently, shunning all brotherhood of their fellow Adeptus Astartes Chapters. The reason for such insular tendencies is unknown, though some believe they are attempting to atone for some great sin committed in their past, and therefore, hide their shame until they can redeem themselves in the eyes of the Emperor.
Graven Souls
Graven Souls Ka Tact Marine.png
The Graven Soul are bellicose Space Marine Chapter whose terror tactics has earned these notorious Astartes a fell reputation across the width and breadth of the Imperium. They were created during the mysterious 13th Founding, the so-called 'Dark Founding', due to the scarcity of any information on this particular Founding or how many Chapters were created at that time. To add to this Chapter's mystery, it is unknown from which genetic lineage they are descended from though they claim to be from the White Scars. Of all the Chapters of the Adeptus Astartes, none exemplifies the virtues of strict self-control more than the Graven Soul. The Graven Soul Chapter culture is one that is very wary of the idea of martial glory or honour, and prefers instead to emphasise pragmatism, adaptability and completion of the mission over all other concerns.
Gray Hussars
Grey Hussars Armiger-Brother.png
The Gray Hussars is a Loyalist, Codex-divergent Space Marine Chapter from the 26th Founding. They descend from the gene-line of Rogal Dorn, Primarch of the stoic Imperial Fists. This Chapter unlike other Imperial Fists successors, doesn't associate themselves with the parent chapter, most of the founding officers being drawn from the zealous Black Templars Chapter and inherited many traditions from their Progenitors. The Gray Hussars prefer mobility, operating a large Astartes Fleet that is continuously enlarged which it operates from without a homeworld.
Great Bears
Great Bears Tact Marine.png
A Successor Chapter of the heroic Blood Angels the Great Bears was created during the 8th Founding, which allegedly occurred during the mid-M34. This Founding was undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. This Chapter has wandered far from the blood-theme of their Progenitors and their fellow Successor Chapters of the Blood. Taking on the symbol of the savage bears of their home planet, the Great Bears hail from a frigid, freezing planet near the Twin Stars of Ursa Major and Minor. Hardy and strong, they will weather any blizzard while unleashing a torrent of firepower against their enemies as they close in for the kill.
Grey Gorgons
Grey Gorgons Pre-Heresy.png
The Grey Gorgons are a formerly Loyalist Success Chapter created from the genetic heritage of the stoic and unforgiving Iron Hands. Created sometime late-M40 during the 25th Founding. For over thousand years, the Grey Gorgons carved their own legends in the annals of the Imperium's history, winning several notable victories and taken part in numerous campaigns and Imperial Crusades. Unfortunately, their meteoric rise of this once-heroic Chapter came to a crashing halt when they became corrupted by the insidious influence of Chaos sometime in the early 900s-M41, during their participation in the Centurion War. As a result the Grey Gorgons Chapter, now renamed the Bringers of Change, found themselves declared Renegades by the High Lords of Terra.

Grey Hounds
GH Captain 1st.png
The Grey Hounds are a Loyalist successor chapter created from the gene-seed of the White Scars during the 21st 'Cursed' Founding. Like many Chapters created during this ill-fated Founding, the Grey Hounds have also suffered unforeseen genetic idiosyncrasies. Almost nothing is known about this Chapter in official Imperial records, save that they share their forefather's battle lust and aggressive style of lightning warfare. Isolationist in their tendencies, the Grey Hounds will fight readily enough alongside other Imperial forces, however they remain aloof, preferring to keep their own counsel, and exchange only what battlefield intelligence they deem worthy of sharing in order to prosecute their campaigns.
Grey Orphans
Grey Orphans Marine Mk VII Variant.png
The Grey Orphans are a Loyalist, non-Codex compliant Space Marine Chapter of unknown lineage, founded in 945.M36 during the 21st Founding, also known as the "Cursed Founding". They were explicitly created to protect the Segmentum Tempestus from the continuous raids and uprising of Chaos Cultists. They are a Chapter of Space Marines that differs completely from the precepts of the Codex Astartes.
Greymanes
Greymanes Primaris Intercessor.png
The Greymanes are a loyalist Ultima Founding Successor Chapter comprised entirely of Primaris Space Marines, descended from the lineage of the Vlkya Fenryka - the feral Space Wolves. Proud and noble, they place a great emphasis on individual skill at arms and valor in battle. They are, in turn, highly individualistic. As with their parent chapter, this sometimes leads to tension with Imperial authorities. Nonetheless, the chapter remains steadfast in its loyalty to the Imperial cause.
Guardians of Osiris
Guardians Osiris Astartes.png
The Guardians of Osiris is a Loyalist Space Marine Chapter created during the 21st "Cursed" Founding; the Chapter was censored by the Inquisition not long after their Founding, as the Adeptus Mechanicus had attempted to create Astartes with incredible resistance and durability. The skin of the Astartes from the Guardians of Osiris have a incredible endurance, making them perfect for battles were they are in the front lines, but the Chapter was affected by an unforeseen genetic idiosyncrasy, a genetic curse they called the 'Vali Rage'. The Guardians of Osiris are also notable for their specialisation in fortifications and defensive tactics, and are normally seen patrolling the Dunes sub-sector located in the Ultima Segmentum.
Gulf Hawks
Gulf Hawks Primaris Intercessor.png
The Gulf Hawks are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the vaunted Ultramarines during the 22nd Founding that occurred in M37. They proudly maintain their stoic heritage of the long lost Terran civilization of Merica. The Gulf Hawks were created to fulfill the needs of a specialist armoured/air-to-ground assault Space Marine Chapter, to counter the myriad threats of the Eastern Fringe - from the malevolent Forces of Chaos that reside within the warp anomaly known as the Maelstorm, to the deadly encroaching Tyranid Hive Fleets and endless Ork fleets that terrorize the Ultima Segmentum. Being successors of the well-organized and highly venerated Scions of Guilliman, the Gulf Hawks are experts in ranged warfare, armoured assault, and air-to-ground strikes. Gulf Hawks Astartes are known for their extensive use of highly accurate boltguns - the Mark VIII 'Colt' Pattern Bolter, as well as possessing a large quantity of Predator Annihilator and Horus Heresy-era Storm Eagle gunships.

Hammer Guard
Hammer Guard Astartes.png
The Hammer Guard are a Codex-divergent chapter of Adeptus Astartes. Their recent discovery of their progenitors, the revered Imperial Fists, has inspired feats of glory in the chapter, and they have started to regain the respect of many chapters who previously thought them tainted. As they pursue their quest for redemption, the Hammer Guard hunt their treasonous brothers across the stars, unwavering in their quest for redemption.
Heralds of the Storm
The Heralds of the Storm, or Storm Heralds, are a 25th 'Bastion' Founding Successor Chapter of the honored Penitent Knights Chapter. Created during M40, the Heralds are a stalwart Crusading Chapter, almost always bringing the Emperor's benedictions to the uncountable battlezones across the Imperium. No battle is too humble nor too indomitable for the Heralds to hesitate in deploying an appropriate response to an enemy of mankind. Being descendants of the Penitent Knights, the Heralds have inherited an incredibly monastic culture, looking to the omens of the God-Emperor to guide them in times of struggle or sorrow, but they also share in the shame of the existence of the Crow's Children Chaos Warband and the mystery of the origin of their gene-seed. But where the Penitent Knights focus on the defense of their demesne of the Asteria Sub-sector, the Heralds of the Storm believe in earning their atonement with relentless victory in the Emperor's name.
Hochmeister

Pict-File Unavailable

The Hochmeister are a semi-Codex adherent Space Marine Chapter. Founded during the 7th Founding with success. They possess even for an Astartes a exceptional robust body and defense against the Chaos. Rumors surround them being not a classic Space Marines. During an investigation the Inquisition and the Ordo Theoreticus found reasons to believe in a very mixed gene-seed. That would explain a quit high mutation rate. Most are just minor or can be prevented. But the transformation of somebody in a Space Marine of this chapter need even more experienced hands as in another chapter. Regardless of the rumors they are for their treatment of civilians and character quite popular.
Holy Hospitallers
Holy Hospitaller Brother.png
The Holy Hospitallers are an ancient Crusading Chapter descended from the zealous Black Templars. They are extremely religious and fervently worship the God-Emperor with their every act. They also are firm believers in protecting the weak and aiding the less fortunate. All Battle-Brothers are expected to receive apothecary training and must be a certified apothecary before advancing to the rank of Preceptor or higher. Their holy mission is to provide aid and protection to Imperial pilgrims on their way to Terra through dangerous space. Typically the Hospitallers handle the escorting of the pilgrim fleets themselves and allow the Commanderies (crusading Battle Companies), usually with a Preceptory or Bailiwick attached, to bring medical aid to any planets in need that they come across on their trek.
Hounds Mortalis
Hounds Mortalis Battleline Marine V2.png
The Hounds Mortalis are a ferocious and bellicose Loyalist Space Marine Chapter created during an Unknown Founding sometime before M36 from unknown lineage. They are notable for their preference for melee combat and ferocity in battle, charging their foes in an unrelenting and unstoppable charge, rending them limb-from-limb in a hail of blood and gore. Little is known of the history of this obscure Chapter, save at some point they destroyed much of their Chapter history and took a vow of silence. Their home world was destroyed and the Hounds became a fleet-based Chapter, forever after plying the space lanes of Ultima Segmentum and protecting Imperial worlds from various threats that might assail them.
Hounds of Kerberos
Hounds Kerebos Assault Marine.png
The Hounds of Kerberos are a Space Marine Chapter whose name has long been a byword for carnage and devastation. Their dichotomous nature manifests in the form of their savage tactics and brutal efficiency which is counteracted by their iron-bound discipline. Their namesake is derived from the creature of ancient Grecian mythology - the gigantic, three-headed hound of Haides, which guarded the gates of the underworld and prevented the escape of the shades of the dead - an apt appellation, as this Chapter continuously guards the Imperium of Man from the myriad of enemies that threaten Mankind.
Howling Wolves
Howling Wolves Astartes.png
The Howling Wolves are a Loyalist Space Marine Chapter who were formed during the 11th Founding in 975.M35, with the purpose of stabilising the Imperium's borders during the Nova Terra Interregnum. They are currently deployed wherever they are needed most. It is unknown from whom they drew their gene-seed from.
Hunters Vigilant
Hunt Vigilant Tact Marine.png
The Hunters Vigilant are a successor of the venerable Dark angels created in the 9th founding.They are a dark and mysterious chapter keen to keep their secrets away from all. The Hunters Vigilant are expert trackers and are able to survive for years alone without backup or help.The Hunt vigilant have a deep burning hatred for chaos as their 5th company was once devastated by a Plague Marine ambush while pacifying a planet into Imperial compliance.This lead to the Hunters Vigilant having a deep mistrust for those they saw as being susceptible to the ruinous powers of chaos.
Hyenas of Caliban

The Hyenas of Caliban are a Dark Angels Successor Chapter based within the Ultima Segmentum. Created during the mysterious 13th Founding, the so-called 'Dark Founding' sometime during M35, this chapter has continued the martial tradition of honour, cunning, and chivalry as well as displaying a strong desire to hunt the Fallen, the traitorous Dark Angels that stain the honour of their beloved primarch. This Chapter is known to utilise more Deathwing Knights and Primaris Hellblasters more than any of their fellow Unforgiven Chapters.

The Ice Dragons are an unconfirmed and unacknowledged Salamanders' Successor Chapter created during the tragic 21st Founding, also known as the 'Cursed Founding', which occurred in 991.M35, on the cusp of M36, shortly before the start of the Age of Apostasy. Initially, the Astartes of this Chapter only suffered cosmetic, physical changes such as distinct albinism. But soon they developed other unexpected, and much more serious, genetic idiosyncrasies - especially the peculiar mutation which necessitated the use of specially-modified power armour due to the Ice Dragons' inability to survive temperatures exceeding sub-zero.
Icebound Sons

The Icebound Sons are a ferocious Loyalist Successor Chapter created from the lineage of the heroic Ultramarines. This Chapter was created during the mysterious 13th Founding, the so-called 'Dark Founding', which occurred in M36. There is very little information about the Chapters created during this time. The Icebound Sons were created as a permanent standing force in the Rivia System, located in the Calixis Sector in the Segmentum Obscurus. Stationed upon the ice world of Sylence, the Icebound Sons stand guard as permanent sentinels against invading Forces of Chaos within the sector. This has earned them the eternal gratitude of the local populace and the moniker, 'The Sons of Sylence'.
Ignitors
Ignitors Tact Marine.png
The Ignitors are an ancient Loyalist Successor Chapter created during the 3rd Founding, claiming lineage from the proud and heroic Salamanders. The Ignitors are known for taking to the battlefield bearing a plethora of flamer weapons. Preceding their fiery assaults with barrages of incendiary missiles, they hurl themselves at the charred, bewildered foe even before the flames have had a chance to gutter out. The Ignitors make their home upon the volcanic world of Accatrix, a planet located in the Ultima Segmentum, not far from the notable Imperial world of Elysia in the Segmentum Solar.
Illuminators
Illuminators Astartes.png
The Illuminators are an 8th Founding Successor Chapter of the Raven Guard. Following a unique structure of 100 Deployments instead of traditional companies, the Illuminators can be found all across the Imperium's myriad battlefields in small teams, supporting other Imperial forces. Their Fortress-Monastery is a captured asteroid in orbit around the Death World Nullepart, fashioned into the shape of a giant head. As the oldest chapter in the Caedis Sector, The Illuminators have guarded its people for millennia alongside their allies in the Blue Flames, Steel Tempests and Jade Paladins chapers and have welcomed the Primaris Marines with open arms. Recently though, it was discovered that the Chapter was hiding a Slaaneshi cult, one which even spread to their own Chapter Master. While the cult was successfully destroyed, the Illuminators now work to atone for the damage dealt by their heretical brethren.
Impalers
Impalers Vyreling.png
The Impalers are a notorious Successor Chapter created from the lineage of the proud and noble Blood Angels during an Unknown Founding. However, extant records indicate, based on eye-witness accounts and circumstantial evidence, that this Chapter was perhaps one of the many ill-fated Chapters created during the lamentable 21st Founding, the so-called 'Cursed' Founding. This Chapter has displayed the worrying traits of an unnatural craving for blood and an insatiable drive to enact retribution against those that dared turn from the light of the Emperor - often in ways both horrifying and extremely more barbaric, as time went on. The preferred method of punishment utilised by these unforgiving Astartes against those that transgressed against the rightful rule of the Emperor was impalement, thus earning this bellicose and savage Chapter the appropriate moniker they would forever after be known and judged by - 'Impalers'. The resulting brutality often enacted during one of their campaigns has led to their being investigated on a number of occasions on charges of heresy and corruption by the Inquisition, but they have been cleared of suspicion, for the time being.

Imperators Veteran Marine.png
The Imperators are a Codex-compliant Space Marine Chapter in the 41st Millennium. They were created during the Third Founding when the Space Marine Legions were broken down into smaller formations, known as Chapters. The newly incepted Imperators Chapter was created from the Ultramarines Legion. The Chapters of this Founding were created in order to replenish the power and might of the Imperium during uncertain times. The Imperators are masters at assault warfare, specializing in breaking down enemy positions via force and wit. They are loyal to the Imperium, but are often dismissive of outside interference in Chapter's affairs, at the dismay of Inquisitors and Imperial allies alike.
Imperial Brothers of the Sword
Imp Bro Sword Knight-Errant.png
The Imperial Brothers of the Sword are a loyalist Adeptus Astartes Chapter, coming from the 23rd 'Sentinel' Founding. Most unusual for a Chapter of this particular Founding is that this Chapter's gene-seed appears to be 'chimeric' - that is, somehow mixed - as it possesses genetic markers from both the the venerable and honoured Ultramarines and the stalwart Imperial Fists. The reasons for why, and whom, had a hand in the Chapter's creation, as well as their intent when they decided to mix the gene-seed of these two dedicated and heroic Loyalist First Chapters, has been lost to the ages. Although somewhat Codex-divergent, the Imperial Brothers of the Sword still abide by many of the rules and guidelines of the Codex Astartes. Though once a very isolationist Chapter that only stayed within their system to defend it, the Chapter has recently began to spread themselves out and help the surrounding sub-sector, and even to the sector that they reside in, within the Segmentum Pacificus.
Imperial Ravens
IR mk6.png
The Imperial Ravens are a Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. They are known for being conservative in nature and most unusual for a Chapter of Adeptus Astartes, are zealous adherents of the Imperial Creed, believing in the Emperor's divinity and Mankind's manifest destiny to rule over the known galaxy. Wherever their assignments take them, the Astartes of this Chapter are known for their ostentatious display of devotion through extensive use of purity seals, Imperial Aquila pendants and prayer scrolls attached to their battle-plate, chanting songs of devotion and prayer, even in the heart of the most fiercest battles.
Imperial Sentinels
Imperial Sentinels Tactical Marine.png
The Imperials Sentinels are 3rd Founding successors of the formerly Seventh Legion, the Imperial Fists, and their Primarch Rogal Dorn. For ten millennia this fleet-based chapter has sailed the dark void of space, watching and waiting for the foes of the Imperium to show their faces. They remember the Imperium as the Emperor had intended, and who is responsible for the death of that dream. They are black armored avengers that stand between the Imperium and those who would see it destroyed.
Imperius Ravagers
Imp Ravagers Tact Marine Bolter 2.png
Known also as the 'Headsmen of Charopós', the Imperius Ravagers are a bloody-handed and bellicose Chapter created from the honourable Ultramarines. Created at the dawn of M32, this Chapter is most unusual for a Successor Chapter created from the lineage of Roboute Guilliman, as the initial cadre was made up of particularly hate-filled, bellicose Astartes - many of which survived the horrors of the Calth Atrocity and the subsequent Underworld War fought beneath the surface of Calth for over a decade after the end of the initial battle. Following their inception this Chapter quickly garnered a fell reputation as both ferocious and unforgiving, wreaking terrible slaughter on those who dared oppose Imperial rule. Since that time, this bellicose Chapter has continued to defend the sovereign realm of the Emperor, and bring swift death to those who dare oppose His will.
Imperius Wardens
Ordo Polis Vigiles Urbanus.png
The Imperius Wardens are a Loyalist Space Marine Chapter of the Adeptus Astartes comprised entirely of the next generation of transhuman warriors - the Primaris Space Marines. They were created from pure lineage of the valiant and much lauded Ultramarines. The stalwart and highly dedicated Space Marines of this Chapter act as the Chamber Militant for the Inquisition's Ordo Aequitas, to serve as enforcers of the Emperor's will and to ensure civil obedience and moral purity of the populace of the worlds of the wider Imperium. They act as judge, jury and executioner to any Imperial citizen they discover having broken Imperial law, as the concept of due process is not one that generally applies in the Imperium. Those who transgress against the Emperor's laws or commit truly egregious crimes, are marked for summary execution, their sentence to be carried out immediately.
Incursors
Incursors Astartes.png
The Incursors are a Loyalist, Codex-compliant Space Marine Chapter of unknown origins created during the 23rd 'Sentinel' Founding. This fleet-based Chapter is an isolated and often reclusive Chapter that rarely works alongside other Imperial military forces or fellow Adeptus Astartes Chapters, and are often accused of being accused of being haughty or lacking in brotherhood. This is mainly due to their neverending Crusade to bring to light of the Emperor to the darkest corner of the galaxy, and despite their isolationist tendencies, this Chapter has continuously defended the realm of the Emperor of Mankind, earning a proud and enviable record of valour and service, comparable to other more senior Chapters.
Inheritors of Caliban
IOC Battle Brother.png
The Inheritors of Caliban are a Codex Compliant Chapter created in the Ultima Founding descended from the venerable Dark Angels. Though a noble and pious Chapter, their name hides a dark secret few of them are privy to. The Inheritors of Caliban did not just inherit the genetic legacy of Lion El'Jonson, but the dark secrets hidden by the Dark Angels. As part of the Unforgiven, the Inheritors of Caliban are a shadowy and reclusive force indeed; seeking to redeem the First Legion's honour at any cost. In battle they favour strong fire lines and lightning assaults to slay a foe as quickly as possible before moving on to the next.
Invictors of Mars
Invictors Mars Astartes.png
The Invictors of Mars are a Loyalist Space Marine Chapter created during the 4th Founding from the lineage of the stoic and unforgiving Iron Hands Chapter. This Chapter has unusually strong ties to the Adeptus Mechanicus, even for a Chapter descended from the lineage of the Gorgon. The Invictors of Mars has a long history of putting itself at the service of the Tech-Priests of Mars and the entire Chapter has often served alongside the forces of Mars' Skitarii Legions. This Chapter specialises in mine warfare, slaying daemonic constructs and assaulting Hell-Forges.
Invokers
Invokers Astartes.png
The Invokers were a partially Codex-compliant Successor Chapter created from the lineage of the venerable Dark Angels during the 18th Founding. They deviated significantly from the credos of the Codex Astartes due to their heritage and training as one of the Unforgiven, employing a Ravenwing and Deathwing formations as well as two additional scout companies due to an unprecedented close relationship to the Exorcists chapter prior to their fall from grace. The Invokers chosen path was one of daemon hunters and masters of the arcane, dealing with the Inquisition to a greater degree than most chapters and most certainly to a greater degree than their fellow Unforgiven. Since their fall from grace, they bolster their lessened numbers with fratricidal daemons and fanatical auxiliary forces of Malladictios now militant populace.
(Excommunicate Traitoris)
Iron Angels
Iron Angels Tact Marine.png
The Iron Angels is a loyalist Codex-compliant Space Marine Chapter created during the 8th Founding from the gene-seed of the Blood Angels Chapter. They hail from the death world of Shool, a planet-sized jungle filled with super-predators and where Humans are forced to live in huge fortresses to protect themselves. Most unusual for a Chapter of The Blood, the Iron Angels are unlike their fellow Successor Chapters, in that they have a tendency to replace lost or severed limbs with bionics. It is unknown if this is somehow ingrained into their psyche or is a result of some form of as-yet determined genetic idiosyncrasy that has yet to be discovered in their Chapter's gene-seed. This Chapter is also known for their close ties with the Adeptus Mechanicus, and as result, their excellent relations with the Omnissian Priesthood has garnered them with expedited delivery of new arms and equipment whenever the need arises.
Iron Beasts
Iron Beasts Drengr.png
The Iron Beasts are a recently created Ultima Founding Chapter consisting solely of Primaris Space Marines. Successors of the ruthless Space Wolves and carriers of Leman Russ's legacy, the Iron Beasts have shown excellent mastery of armoured and mechanized warfare, backed up by their quick moving attacks and ferocious talents in close combat.
Iron Bison
Iron Bisons Tact Marine.png
The Iron Bison are a semi-Codex compliant loyalist Space Marine Chapter of an Unknown Founding created from the lineage of the White Scars. They are currently engaged in a conflict with the Withered Hands Chaos Space Marines to reclaim several conquered worlds under the Iron Bison's protection. The Iron Bison Chapter primarily engage in hit and run and fast attack tactics, but a mutation in their gene-seed gives them a unique empathetic awareness of their environment, allowing them to sense enemies hidden behind cover or by unnatural means. This trait makes excellent for scouting and hunting parties and it is not unheard of for a company of Iron Bisons to be sent out to find hidden enemy bases for other chapters or to stalk an enemy who has escaped the watchful eyes of the Imperium.
Iron Blood
Iron Bloods Astartes.png
The Iron Blood are a Loyalist Successor Chapter descended from the lineage of the stoic Iron Hands, one of the few bits of information still available to them about their past after near crippling defeats that nearly destroyed their Chapter. Created during an Unknown Founding, the Iron Bloods are not even certain if they are direct successors or spawned from another Successor Chapter, though evidence points to the latter. At present the chapter has recently returned to full strength and is eager to prove themselves and erase past shames of defeat. They are commonly called the 'Iron Blooded'.
Iron Dragons
ID Tactical Marine.png
The Iron Dragons are an ancient and honourable Loyalist Space Marine Chapter that was created during the 3rd Founding in 001.M32. Due to their similar heraldry, chthonic traditions, beliefs and practices, the Iron Dragons are suspected to have been created from the lineage of the venerable Salamanders of Nocturne. Like their supposed forebears, the Iron Dragons are also well known for their similar humane treatment and concern for the lives of innocent citizens of the Imperium as their supposed Progenitors. However, their divergent beliefs in the Promethean Cult and reverence for their Primarch Vulkan above all else, whose Chapter cult is centered around his worship, is considered unseemly by the Salamanders and not in keeping with their Primarch's original teachings.
Iron Drakes
Iron Drakes Intercessor.png
The Iron Drakes are a Loyalist Successor Chapter, which are known for their selflessness and for their absolute fearlessness in battle. The were allegedly derived from the heroic and brave lineage of the ancient Salamanders Chapter. They have a strong connection with humans and protect those that can't defend themselves. The Iron Drakes excel at the use of fire-based weaponry and close combat. In battle, they feel no fear and never run from the enemy until every innocent person is safe. The Chapter has a good connection with their Progenitors and proudly call themselves "Sons of Vulkan".
Iron Gorgons
Iron Gorgons Mk IV 2.png
The Iron Gorgons are a Successor Chapter of the stoic and unforgiving Iron Hands. This Chapter, along with the Sanctors of Manus and the Templars of Iron, make up a triumvirate of 2nd Founding Iron Hands' Successors, collectively known as the Frateris Firmitatis ("The Ironclad Brotherhood"). The Iron Gorgons were Founded from a portion of the Iron Hands Chapter's Voraag Clan - survivors from the infamous Dropsite Massacre of Isstvan V. This clan was comprised of aggressive, brutal and willfully petulant elements of the original X Legion, who refused to recognise the authority of the newly appointed Iron Council following the aftermath of the Horus Heresy. When the High Lords of Terra decreed the 2nd Founding in 021.M31, the Iron Hands Chapter used this opportunity to purge themselves of this troublesome clan. Since that time, the Iron Gorgons Chapter have proven themselves as true Scions of Ferrus Manus, garnering a reputation as an unassailable and resolute Chapter of Space Marines.
Iron Guard
Iron Guard Mk VII.png
The Iron Guard is a Loyalist Successor Chapter of Adeptus Astartes created from the lineage of the stoic Imperial Fists during the 23rd Founding, to so-called 'Sentinel Founding'. These Scions of Dorn are known for their extensive use of both regular and heavy bolter weaponry as well as their distinct lack of Assault Marines.
Iron Harbingers
Iron Harbingers Clan-Brother.png
The Iron Harbingers are a particularly grim and ruthless Successor Chapter that hails from the tragic legacy of the unforgiving Iron Hands. They were created in the wake of the tragic events of the Horus Heresy and the subsequent Great Scouring that ended in 021.M31, during the 2nd Founding. The Iron Harbingers were founded from a portion of the Iron Hands' Clan Kadoran, one of the oldest Clan Companies of the Iron Hands Legion during the Great Crusade and Horus Heresy eras, which incorporated many of the Legion's Terrans. This clan was also notable for being masters of scientific and technical pursuits as well as being cunning practitioners of siege warfare and the oft-misunderstood arcana of Cybertheurgy. Following their inception the Iron Harbingers, along with the Iron Gorgons, Templars of Iron and the Iron Invictors, formed an unofficial quadrumvirate of other Iron Hands Successor Chapters created during this Founding, known as the Frateris Firmitatis ("Ironclad Brotherhood").
Iron Myrmidons
Iron Myrmidons Mk VII&III.png
The Iron Myrmidons are a mostly Codex-compliant Imperial Fists Successor Chapter from the 4th Founding, after the disastrous War of the Beast, with a focus on Zone Mortalis combat & siege warfare. They are a proud and tenacious chapter, rarely devolving into savage or overly brutal conduct but instead are an unrelenting tide of adamantium & ceramite sending precise volleys of bolter fire into their foes while vehicles and heavy specialists move ahead.
Iron Purity
Schema de Couleur Iron Purity Primaris.png
The Iron Purity are an ancient and stalwart Loyalist Successor Chapter created from the proud lineage of the Ultramarines, supposedly created as early as the 2nd Founding, following the bloody civil war of the Horus Heresy and the subsequent Great Scouring. An honourable and dedicated Chapter, the Iron Purity have continuously fought the enemies of Mankind for ten millennia, standing as a bulwark between realm of the Emperor and the encroaching darkness of the Ruinous Powers.
Iron Retributors
Iron Retributors Astartes.png
The Iron Retributors are a loyalist Successor Chapter created from the lineage of the grim and unforgiving Iron Hands during the 10th Founding sometime during mid-M35, created amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. Posted just over the borders of the Segmentum Pacificus, the newly formed Chapter claimed the backwater feudal world of Geyron Prime. The Iron Retributors were created following the success of a single squad from Clan Raukaan Iron Hands led by Sergeant Flavius Byzantum following the successful purged of a massive space hulk from unknown xenos. The Chapter embraced the Codex Astartes without losing their long lost tradition as Sons of the Gorgon.
Iron Revenants
Iron Revenants Primaris Intercessor.png
The Iron Revenants is a Loyalist Codex Astartes-compliant Space Marine Chapter. The Iron Revenants is a Successor Chapter of the stoic and unforgiving Iron Hands considered part of the Ultima Founding, although their original chapter records extend back to the troubled 36th Milleniun, a time of great upheaval.
Iron Seraphs
Iron Seraphs Intercessor.png
The Iron Seraphs are a fleet-based Successor Chapter descended from the venerable Angels of Absolution, whom themselves are descended from the ancient and mysterious Dark Angels Chapter. This Chapter is comprised entirely of Primaris Space Marines, created during the most recent Ultima Founding. As a fleet-based Chapter, the Iron Seraphs are highly active at prosecuting the wars of the Imperium against the myriad of enemies of Mankind. Like their fellow Unforgiven Chapters, the Iron Seraphs are driven to prosecute the Dark Angels' secret war against The Fallen, and are more than willing to answer their progenitors' call to war in order to achieve their objectives.
Iron Spears
Iron Spears BattleBrother.png
Hailing from the feudal world of Ailinne, the Iron Spears (Hastae Ferrum in High Gothic) are a 22nd Founding Successor Chapter of the Blood Angels. Operating from their fortress-monastery of Dunbairrche, the Iron Spears are deployed across the Segmentum Obscurus and Segmentum Ultima. The Chapter has been led by High Chieftain Fionn Cathair for nearly five centuries since his predecessors passing in 634.M41.
Iron Templars
Iron Templars Tact Marine.png
The Iron Templars are an ancient Chapter descended from the lineage of the venerable Dark Angels. Believed to have been created in 021.M31 during the Second Founding, the Iron Templars have continued to follow in the footsteps of their genetic forbears, to relentlessly hunt down every single Fallen Angel and force them to repent. Despite their secretive nature and dedication to seeking out the Fallen, the Iron Templars have garnered a reputation as an honourable and dedicated Chapter who fiercely protect their planetary system of Aquitaine against the gathering darkness from Chaos, xenos and the myriad threats that threaten the Imperium on all sides. As a Chapter steeped in the feudal traditions of its Chapter home world, the Iron Templars' doctrines, traditions, and organisation reflect their particular approach to prosecuting the Imperium's wars.
Iron Wardens
Iron Warden Wearing Mk III.png
The Iron Wardens are Founded in late M35, partly due to the events of the Moirae Schism, which caused them to split from their progenitors - the stoic and unforgiving Iron Hands. While these outcasts would go on to prove themselves loyal as the Sons of Medusa, the Iron Wardens themselves would go to prove themselves as tactically brutal Space Marines. Like their forebears the Wardens have close a relationship with the Adeptus Mechanicus. This not only allows the chapter to use and maintain advanced weapons and vehicles but often the chapter will march alongside the Skitarii and other forces of Mars. This however leads the chapter to accept numerous missions from the Mechanicus often without questioning the orders given. This has lead to clashes with other parties - both chaos and xenos alike.
Ironclad Templars
Ironclad Templars Tact Marine.png
The Ironclad Templars are a Loyalist 3rd Founding Space Marines Chapter derived from the lineage of the stoic Imperial Fists but are more alike their sword brothers of the zealous Black Templars. The history of the chapter was lost during the First Defense of Aevis, where part of the chapters vaults was burned down by Drukhari Kabalite Warriors. The number of crusades the chapter have been on is unknown as the records where lost in the vault fire, but what is known is that somewhere fought alongside the Black Templars. The chapter is Codex Astartes-compliant, unlike their Black Templar brothers. The chapter has just under 1,000 Astartes.

Jackal Claws
Jackal Claws Marine.png
The Jackal Claws are a semi-Codex compliant, rare Successor Chapter created during an Unknown Founding from the lineage of the stealthy and foreboding Raven Guard. This Chapter is notorious for their isolation and tendency to scavenge battlefields. They are also known for being respectable snipers and masters of stealth. Furthermore, they are noted for being incredibly distant from their progenitors and fellow successors, not due to circumstances of distance or duty, but out of distrust and resentment towards Corvus Corax for banishing their ancestors long ago.
Jade Knives
Jade Knives Tact Marine.png
The Jades Knives are a Loyalist Successor Chapter created from the lineage of the proud and noble warrior, Primarch Jaghatai Khan of the wild and savage First Founding White Scars. This Chapter was created as one of several newly incepted Chapters during the 26th Founding in 738.M41. The Jade Knives were created to stand as a bulwark against the new xenos presence in the Eastern Fringe of the Ultima Segmentum - the ever-expanding Tau Empire. Following the death of their first chapter master, the Chapter was torn in two, which resulted in an internecine conflict that nearly saw the Chapter destroyed before it had barely been able to make its mark in the annals of Imperial history. This destructive conflict resulted in the Chapter being torn in two, due to their divergent believes and differences in overall beliefs. This resulted in the formation of a Successor Chapter - the Jade Paladins. Despite this troubled era, the Jade Knives rose from the ashes of their near-destruction, and have continued to prove themselves as stalwart and dedicated defenders of the Imperium.
Jade Wyverns
Jade Wyverns Primaris Intercessor.png
The Jade Wyverns is a Salamanders Successor Chapter created during the recent Ultima Founding and comprised entirely of Primaris Space Marines. Formed from the ranks of the Unnumbered Sons, or "Greyshields", during the Indomitus Crusade led by the re-born Ultramarines Primarch Roboute Guilliman, they have been tasked with bolstering the defenses of the Imperium Sanctus against the forces of the Ruinous Powers, various xenos threats and any other enemies of the Imperium.
Jiangshi Riders
Jiangshi Riders Astartes.png
The Jiangshi Riders are a loyalist Chapter who, due to their mutations and behavior, are highly suspected as originating during the 21st 'Cursed' Founding. Contrary to the nature of others from the Cursed Founding, the Jiangshi Riders have been known to work with the Inquisition, utilising their select tactics and culture to aid them when called. While still untrusted by the Imperium at large, this tie to the Inquisition has spared the Jiangshi from being declared renegades for their violent ways and reputation, although their gene-seed, only 70% of which is of White Scars origin, has been demanded numerous times for investigation. Uncaring of this, they act as the judge, jury, and executioner of the traitor, and entire worlds will descend into a hellscape of fear, created by them as they weed out those unworthy of the mercy of the Emperor.
Jonmarines
Jonmarines Tact Marine.png
The Jonmarines are a Loyalist semi-Codex compliant Successor Chapter of the noble and accursed Lamenters Chapter, which hails from the lineage of the angelic Primarch Sanguinius, and, whilst partially understood by the Jonmarines themselves, the Praetors of Orpheus Chapter. Created in 927.M41 during an unstated Founding, the Jonmarines were the former protectors of the Lawsunda Majoris system, until disaster befell them during the disastrous events known in Chapter annals as the Howling Dark. Forced to enact Exterminatus upon their own Chapter home world, the Jonmarines henceforth became a fleet-based Chapter, and now bring both bolter and blade to the enemies of Mankind on their own terms, wherever citizens of the Imperium cry out for aid.

Keepers of the Accord
Keepers of the Accord(redesigned).png
The Keepers of the Accord are a Loyalist Chapter of the Adeptus Astartes shrouded in mystery and symbolism, thus worthy successors of the Dark Angels and their Primarch Lion El'Jonson. Presumably - like their forebears and brother Chapters, the Keepers are part of the Unforgiven - the brotherhood of Chapters that hunt the Fallen Angels. However, they are distant from their fellow Unforgiven, not because of a grudge or spite, but because of their creation. Despite the tactic approval of the High Lords of Terra the Chapter's creation, their inception is mired in classification and mystery. What is known is that the Keepers have always stood vigil over a wandering planetoid named "Thessalon" from a great space station acting as their Fortress Monastery of Caelestis Castellum. The Keepers of the Accord maintains a rather high number of Techmarines among their ranks, and thus have an impressive quantity of Land Raider patterns in their armory.
Kings Fangs
Kings Fangs Veteran Marine.png
The Kings Fangs are a Loyalist Space Marine Chapter that was discovered in 800.M36. There is very little information on this enigmatic Chapter, including when they were exactly created and from whom. However, Imperial scholars believe this Chapter's inception could coincide with the infamous and little-known 13th Founding, to so-called 'Dark Founding'. The Kings Fangs do not share a common genome with the rest of the Chapters of the Adeptus Astartes and their origins have long since been forgotten. Only a few rare people still alive in the modern era, possess this knowledge locked in their memory.
Knight Paragons
Knight Paragons Primaris Intercessor.png
The Knight Paragons are a loyalist semi-Codex compliant Space Marine Successor Chapter created from the lineage of the proud and glorious Salamanders during the late M41 and the Ultima Founding. They are a honorable and compassionate Chapter and believe that to protect the lives of the Emperor of Mankind's innocent subjects is one of their most important duties.
Knights Celestial
Knights Celestial Tact Marine.png
The Knights Celestial are an ancient and proud Loyalist Space Marine Chapter created during the 2nd Founding. Officially, they are listed in official Imperial records as a Successor Chapter of the venerable and Honourable Ultramarines. They are notable for being a zealous and highly religious force and believe the Emperor to be a God And that they are his angels. Unbeknownst to any outsiders, the Chapter also believes they hail from the lineage of the traitorous Emperor's Children.
Knights Despoilers

Pict-File Unavailable

Created during the 26th Founding, the Knights Despoilers were created as a Successor Chapter of the Red Crusaders, whose lineage is unknown. Striking from the void relentlessly and eager to punish the unworthy, the Knights Despoilers embody the fervent zeal of their foster chapter, the Red Crusaders. The Knights exploit these terror tactics to quickly disencourage most opposition, being specialists in dealing with planetary rebellions and cultist uprisings.
Knights of Aryith
Knight of Aryith Astartes.png
The Knights of Ayrith is a Loyalist Space Marine Chapter created during the ill-fated 21st Founding, the so-called "Cursed Founding". They were supposedly created from the lineage of the heroic Blood Angels, characterised by their brutality and their radical vision of the Imperium. Despite several investigations into the Chapter's true lineage, their origins have never been definitively verified.
Knights of Guilliman
KoG Mk VII Variant Armor.png
The Knights of Guilliman are a Loyalist Successor Chapter of Novamarines descent and through them the Ultramarines. As expected from those of the Roboute Guilliman's blood, they are staunch adherents to the Codex Astartes and are often at odds with those that scorn it. Their homeworld is a feudal world very similar to the ancient Dark Angels' homeworld of Caliban. They are currently on a penitent crusade for siding with the Secessionists during the war known as the Centurion War. The Centurion War was fought in late M41 between the forces of the Imperium and Adeptus Mechanicus Secessionist forces under the rule of Magos Atilla who seized control over several Forge Worlds and led an attempt to secede from the Imperium.
Knights of Iscariot
Knights Iscariot Tact Marine.png
The Knights of Iscariot are a 3rd Founding Successor Chapter of the Dark Angels. Unlike most Astartes Chapters, the Knights of Iscariot worship the Emperor of Mankind as a genuine god. They are also known to be specialists in hunting down traitors, heretics, and daemons. The Chapter's faith and specialty has led them to forming good relations with the Ecclesiarchy, the Ordo Malleus and the Ordo Hereticus. Despite their good reputation among the Ecclesiarchy and the Inquisition, the Knights of Iscariot are not immune to the dark and foreboding nature of their forebears. In spite of their spectacular service record and abundance of religious zeal in the present, their past remains shrouded in mystery and contains many a dark secret.
Knights of Sol
Knights Sol Tactical Marine.png
The Knights of Sol are a Loyalist Space Marine Chapter from the 19th Founding, descended from the Primarch Rogal Dorn and successor to the Black Templars Chapter, a proud heritage they strive to uphold with honor and courage, the Chapter constantly struggles against the forces of Traitor Legions and Chaos Daemons, and zealously defend their homeworld of Valium from the foul taint of Chaos. They are known for their proud Knightly culture and the great importance they give to honour, brotherhood and chivalry, as well as their disregard for combat vehicles and their preference for melee combat. Their pride works against them in many cases, specially when they refuse to hide their Chapter's Heraldry with camouflage.
Knights of the Anvil
Knight Anvilar Tact Marine.png
The Knights of the Anvil, also known as the Anvilars, are a Loyalist Space Marine Chapter created during an Unknown Founding and are of uncertain lineage. Though their exact origins are unknown, they first appear in Imperial records as far back as M34. The Anvilars serves as one of the Hell Warders Chapters - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the 'Hellgates', the dual warp storms located in the Segmentum Solar which are located uncomfortably close to Holy Terra. The Anvilars are the only Chapter out of the five whose presence in Sector Occident Prime predates the First Hell Crusade.
Knights of the Throne
Knights Throne Tact Marine.png
The Knights of the Throne, known in High Gothic as the 'Thronus Equites', were once a noble if somewhat young Successor Chapter created from the lineage of the heroic and stalwart Blood Angels. Cursed with an even higher decree of their angelic gene-sire's prognosticative abilities, the Chapter suffered from horrific visions of their fall, which showed them succumbing to one of their gene-line's twin genetic curses - the Red Thirst. However, through these prophetic visions they also saw the promise of their deliverance, which unfortunately proved false and led to the downfall of the doomed Chapter, as half of them fell to the unnatural rage and blood-seeking madness of those who follow the Chaos Blood God Khorne, and led to half the Chapter becoming the notorious Chaos Warband, the Angels of the Voracious Chalice.
(Traitoris Perdita)
Knights of the Watch
Knights Watch Astartes.png
The Knights of the Watch are not a standard Chapter but a fellowship of veteran Astartes who, inspired by the example of the loyalist Death Guard Battle-Captain Nathaniel Garro - Agentia Primus of Malcador the Sigillite - have left their Chapters to follow the path of Errantry, to seek out and destroy the enemies of the Emperor wherever they might be found.
Knights of War
Knights War Battle-Brother.png
The Knights of War are a Loyalist 23rd 'Sentinel' Founding and rare Successor Chapter of the highly venerated White Scars. The Knights of War are notable for their duality of character - being a highly aggressive and bellicose Chapter which are brutal to their foes almost to the point of savagery - but are also known for their nobility of character.
Kraken Sons
Kraken Sons Primaris Intercessor.png
The Kraken Sons are specialised force, much like the Wolfspear, they were created to contain the servants of the Ruinous Powers, in the case of this Ultima Founding Primaris chapter, they were created to try and annihilate the notorious Chaos Lord Huron Blackheart and his marauder empire. Unlike the Wolfspear however, the Kraken Sons were practically gleeful at this posting. Ever since they've made their home on the world of Miðgarðsormr the starlanes about Badab have been alight with the fires of combat; the Kraken Sons and the imperial navy taskforce assigned to aid them have relentlessly chased the Red Corsairs. Though they have not managed to completely obliterate Huron and his empire the Kraken Sons have managed to curb the Tyrant of Badab's raids into their former sector.

Lightning
Lightning Astartes.png
The Lightning are a White Scars Successor Chapter created during an Unknown Founding, although many Imperial savants believe they were possibly created during the 21st Founding, the so-called 'Cursed' Founding. The Lightning are based upon the planet Saka located in the Thermopylae sub-sector of Sector Occident Prime. They currently serve as one of the Hell Warders - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the 'Hellgates', the dual warp storms in the Segmentum Solar which are uncomfortably close to Holy Terra.
Lightning Sons
Lightning Sons-1.png
The Lightning Sons are a loyalist Adeptus Astartes Chapter of unknown founding and origin; their recorded history prior to the Burning of Veritan has all but been lost to the wider Imperium. Chapter belief dictates that they are the descendants of one of the Imperium's lost sons, however these beliefs have come under scrutiny from the Lord Regent's own Logos Historica Vertia. Since the opening of the Cicatrix Maledictum in ca. 999.M41, and the launch of the Lord Regent's Indomitus Crusade, the Lightning Sons have continued the bitter fight for humanity's survival across a hundred worlds.
Lightning Wraiths
Lighting Wraiths Tact Marine.png
The Lightning Wraiths are a Loyalist Space Marine Chapter founded in M37 as a Successor Chapter to the White Scars. As such, the Lightning Wraiths retained some of the White Scars' traditions and combat doctrine. They were created in response to an increase in Chaos activity in the Segmentum Obscurus. A chapter born from shame, hate, and vengeance, the Lightning Wraiths are a reclusive chapter with traditions that derive from various death and warrior cults of their home planet. Marines hailing from the chapter are taciturn individuals, speaking only when the situation requires clear and concise communication. Even then, they speak very little to those who are not of the Lightning Wraiths. The only exception to their introverted attitudes are the White Scars, as the Lightning Wraiths are fanatically loyal to their forefathers. However, in the fields of battle, the normally introverted marines turn into savages fuelled by their undying rage.
Lions Malevolent
LM Tactical Marine.png
The Lions Malevolent are a Successor Chapter of the line of Primarch Lion El'Jonson, supposedly created during the 5th Founding sometime during M33, as they were counted amongst the many Adeptus Astartes Chapters deployed during the Lagomort War fought in 238.M33. As descendants of the Lion they are a part of the Dark Angels Successor Chapters collectively known as the Unforgiven. Like the Dark Angels, they too, formed their own Inner Circle to guard the knowledge of their progenitor's secret shame. This Dark Angels Successor Chapter displays a particular zeal in prosecuting their quest against the Fallen Angels. Nothing can dissuade them from this most sacred of quests, to right the ancient wrongs of their progenitors. Even though the Chapter has proven itself in battle, their help is sometimes refused due to their reputation for acting against orders and on occasion withdrawing from a campaign in order to pursue their own, undisclosed ends.
Lions of Babylon
Lions Babylon Tact Marine.png
The Lions of Babylon are a ferocious and bellicose Successor Chapter of the unforgiving Sable Lions, who themselves hail from the lineage of the stoic Primarch Rogal Dorn. The Lions of Babylon were created sometime during mid-M35, amid the dark times of the Nova Terra Interregnum, when the Imperium of Man was split into seperate interstellar empires. Since their inception, this unforgiving and bellicose Chapter have continued to stand sentinel along the furthest reaches of the Imperium's domain, standing eternal vigil against invading Forces of Chaos and xenos raiders that would dare assail their both their home system and those nearby Imperial worlds loyal to the Imperium of Man. Most unusual, the Lions of Babylon adheres closely to the dictates of the Imperial Creed, sharing many of its teaching and beliefs. The Lions see themselves as superior to the average human, for they believe they are the chosen people of Anu (the God-Emperor), and try to show it at every given opportunity. This attitude often causes friction between the Lions and other Imperial organisations.
Lorekeepers
Pict-File Unavailable
The Lorekeepers are a Loyalist Successor Chapter created from the lineage of the ancient Dark Angels during the 7th Founding. This specialist Chapter was created for the sole purpose of seeking out and acquiring lost archeotech technology and missing Standard Template Construct (STC) fragments from the Dark Age of Technology. As true warrior-monks of the Emperor, the Lorekeepers are assiduous in the acquisition of ancient lore and missing technology as well as the detailed documentation of their findings for their Chapter's extensive collection of archaic lore.
Luna Berserkers
Luna Berserker Astartes.png
The Luna Berserkers are a Codex-divergent Blood Angels Successor Chapter created during the ill-fated 21st Founding, to so-called 'Cursed Founding'. Several Chapters created during this particular founding suffered from rampant mutations or aberrent gene-seed. The result of various genetic meddling resulted in the Luna Berserkers to possess an odd quirk in their gene-seed - the twin-flaws of both the Black Rage and Red Thirst possessed by the Blood Angels and those of their bloodline, is near-constant within them, however, it fluxes with the phases of the moon.
Lunar Guard
Lunar Guard Astartes 2.png
The Lunar Guard are a Loyalist Space Marine Chapter of unknown lineage created during the 9th Founding. Once engaged in the tasks of the Ecclesiarchy, to ensure the farthest corners of the Imperium were brought the Emperor's light. after sustaining huge losses they decided to gain a foothold in the Boras Minor sector, which they could then call their home. For their entire existence, the Lunar Guard have been distinguished by their successful notable campaigns and maintaining the Emperor's order within the Boras Minor sector. Under eternal siege by marauding Orks and plundering fleets of Drukhari, the Chapter has gained vast amounts of experience when countering these xenos threats.
Lycanthropes
Lycanthropes Astartes.png
The Lycanthropes are a savage and mysterious Space Marine Chapter created during the 21st 'Cursed' Founding from unknown lineage. This chapter of Adeptus Astartes teeters on the edge of the Ordo Astartes' tolerance. Brutal and mindlessly violent on the battlefield, they have garnered a grim reputation of carnage and bloody retribution. With no planet to call their own the Lycanthropes are an insular chapter, their offerings of the enemies blood made both to their unknown Primarch (many theorising it to be Leman Russ) and the God-Emperor.
Lyran Guard
Lyran Guard Veteran.png
The Lyran Guard is a 12th Founding Loyalist Successor Chapter of the Imperial Fists created in M35 during the time period of the Nova Terra Interregnum. Given the duty by the High Lords of Terra to protect the Gierland Sector from xeno and chaos incursion.

Maelstrom Fists
Maelstrom Fists Primaris Intercessor.png
The Maelstrom Fists is a solely Primaris Space Marine Chapter created during the Ultima Founding, formed from the lineage of the Indomitable Imperial Fists. A rather unique chapter, the Maelstrom Fists were formed to specialize in void warfare, to compensate for the losses that the Imperial Navy suffered during the 13th Black Crusade and the formation of the Great Rift. Thus, the newly formed Chapter chose the ocean world of Pontus as their homeworld.
Mandators
Mandators Intercessor.png
The Mandators are a Loyalist Codex-compliant Space Marine Chapter created during the recent Ultima Founding from the proud and heroic lineage of the Ultramarines. They are comprised entirely of newly revealed Primaris Space Marines, the next stage of evolution of the transhuman warriors of the Adeptus Astartes. This Chapter has close ties to the Inquisition in the Aurum Sector.
Manticores
Manticores Tact Marine.png
The Manticores are a Renegade Chapter, originally part of the 'Cursed' 21st Founding and successors of the Dark Angels, thus making them a part of the Unforgiven. Despite being titled as traitors, that is far from the truth. Near the ending of the 40th Millennium, the Chapter was in pursuit of the infamous Fallen Angel, Cypher, that lead to the Manticores coming into conflict with the Inquisition. Rather than revealing the dark secret of the Fallen, the Manticores took the blame and were thus declared traitors. Now they roam the galaxy, chased by their former comrades, with only their fellow Unforgiven knowing the truth. The Manticores continue to protect the Imperium, while at the same time hunting down the Fallen, in hopes of one day redeeming themselves in the eyes of the God-Emperor.
Maroon Hunters
Maroon Hunters Astartes.png
The Maroon Hunters are a loyalist, 26th Founding chapter that descends from the gene-seed of the Great Khan, Jaghatai. Founded to patrol the fringes of Segmentum Pacificus and protect it from xenos assaults, the Maroon Hunters have stood compliant to the Codex Astartes and have developed a rather unique culture compared to their primogenitor. A noble and fearsome chapter, they specialize in combating xenos and have adopted expeditionary as well as submissive tactics in order to quickly pacify or conquer a planet. An aggressive chapter when it comes to pacifying xenos, the Maroon Hunters are notorious warriors, fierce combatants and soldiers unwilling to retreat.
Marauding Eagles
Marauding Eagles Astartes.png
Created around mid-M34, during the 8th Founding, the sole known successor Chapter of the Destroyers, and through them the White Scars, the Marauding Eagles are the members of an infamous Chapter, whose berserk frenzy has caught the gaze of the Inquisition and the Adeptus Mechanicus. Like their forefather, their bloody conduct in war is marring their otherwise little but effective known records of engagements. However, the many dangers of the Halo Stars against which they stand ever vigilant have always allowed them to evade sanctions.
Martyrs Vindicant
Martyrs Vindicant Tact Marine.png
The Martyrs Vindicant were a semi-Codex compliant Blood Angels Successor Chapter established during the 15th Founding sometime in M35, upon the death world Helis in the Segmentum Ultima. The Chapter would become famed for its fanatical hatred of Orks, often abandoning battlefield objectives and even dooming entire campaigns in an attempt to slaughter any greenskin presence the chapter became aware of. Helis would remain the Chapters' home world until the late years of M38, when an apocalyptic Ork WAAAGH! drove the Martyrs from the planet, forcing them to roam the stars as a fleet-based chapter. The Martyrs would roam the stars of the galaxy until 999.M41, when during the fleets speedy journey to Baal during the Third Tyrannic War, the Cicatrix Maledictim - a massive tear in reality that stretched across the width of the galaxy - flinging the entire Chapter fleet into the depths of Warp space.
Masonic Marines
Masonic Marines Tact Marine.png
The Masonic Marines are a semi-loyalist, non-Codex compliant Space Marine Successor Chapter created from the lineage of the stoic and brave Imperial Fists. Some Imperial records state that the Chapter was created during the 3rd Founding in early M32, while other records do not mention the Chapter until late 41st Millennium during the recent Ultima Founding. There are also diffrent views on the allegiance of the Chapter. Some sources puts the Masonic Marines as a true loyalist Chapter, while other describe them as renegades.
Mastodons
Mastadons Primaris Intercessor.png
The Mastodons are a Loyalist Space Marine Chapter created during the most recent Ultima Founding from unknown lineage. Their Chapter Master, Aldrick Thunderborn, and his council alone knows the Chapter's original genetic material, not wanting the gene-seed to direct the Mastodons in how they fight, keeping this knowledge as a tightly held secret. As siege warfare specialists, the Mastodons utilise slow, methodical, precision warfare followed by crushing armoured assaults with overwhelming firepower. Due to their preferred fighting style, the entirety of the Chapter is comprised entirely of Primaris Marines. In battle, the Chapter's planetary assaults are spearheaded by a mobile fortress, a massive city-sized land crawler that is transported by an ancient Ark Mechanicus, gifted to the Chapter following a campaign where they helped destroy a series of Dark Mechanicus fortresses.
Maws of Fenris
Maws of Fenris BattleBrother.png
The Maws of Fenris is a Loyalist Codex Astartes-compliant Space Marine Chapter born of the recent Ultima Founding, and a Successor Chapter of the Space Wolves, composed entirely of Primaris Space Marines. The Maws of Fenris were amongst the first of the Primaris Chapters created in the Ultima Founding. The Maws of Fenris' homeworld is Tûndar, located in the Ultima Segmentum. Though their battle record is still growing, they have already established themselves, having fought against the Orks and the Forces of Chaos.
Megalodons
Megalodons Void-Brother Mk III.png
The Megalodons are a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage. This savage and merciless Chapter were reputedly created in antiquity, but their exact origins are difficult to pinpoint by Imperial scholars, remaining shrouded in the midsts of long-lost antiquity, thousands of years in the past. An isolationist and aloof Chapter, the Megalodons have continuously prosecuted their solitary crusade for millennia, bringing the light of 'Monatoa', 'The Void Shark that Devourers' (God-Emperor), to the darkest corners of the galaxy. Like hungry apex predators, they stalk through the cold, dark depths of the void, striking their foes unexpectedly and tearing them apart, then slip back into the Outer Dark. The Megalodons' ruthless reputation has writ a bloody legacy across the pages of Imperial history, their very name having become synonymous with merciless butchery of those who would dare assail the realm of Mankind.
Midnight Claws
Midnight Claws-2.png
The Midnight Claws are a Loyalist Space Marine Chapter created during the ill-fated 21st Founding, the so-called 'Cursed' Founding, from chimeric gene-stock from the dual lineages of the Raven Guard and White Scars Chapters. The Chapter has combined both sides of heritage into their belief system and speciality - opting for fast attacks during cover operations.
Molten Fists
Molten Fist Primaris Intercessor.png
The Molten Fists are a semi-Codex compliant Space Marine chapter founded during the ill-fated 21st 'Cursed' Founding. They are sons of Primarch Rogal Dorn through the Crimson Fists. Although they have an official homeworld that the chapter returns to at least once every decade, they act mostly in a fleet-based capacity due to its location in the Segmentum Obscurus. Due to their inception during the Cursed Founding, the chapter suffers from a gene-flaw named the 'Internal Flame'. In essence, the marines of the chapter suffer a constant burning pain which they have to manage. However, this does come at the bonus of having a resistance to heat and flame that rivals that of the Salamanders. A marine's worth in the Chapter is frequently based upon his control of this pain. The Chapter's gene-flaw means that they make heavy use of melta weaponry, to the extent of outfitting their new Hellblaster squads with modified melta guns.
Moonlight Stalkers
Moonlight Stalkers Primaris Intercessor.png
The Moonlight Stalkers are a Loyalist Successor Chapter whose lineage was derived from the wild and fearless Space Wolves. The were founded pretty early in the Ultima Founding, which means they're comprised entirely of Primaris Space Marines. They strike from the shadows, surprising and overwhelming the enemy forces. The Moonlight Stalkers don't like open battle and they prefer more dense terrain, were the enemy is forced to face them in close-combat. They stalk their enemies and are tireless in the pursuit of their prey. As the name suggests they prefer hunting their prey at night, were they can move unseen and surround the enemy without them noticing until the last second.
Mordekaisers
Mordekaiser Mk VII Armour.png
The Mordekaisers (translated to High-Gothic as 'Murder Lords') are a Successor Chapter created as a 24th Founding of the Imperial Fists. Upon their creation, the Mordekaisers were sent to the far reaches of the Galaxy into the Ghoul Stars. Their destination was the Imperial Starport Morgen Schwach ('Morrow Dim'), located near Lunaphage before the Malefactus Warp Rift. They specialise in lightning fast assaults that take out multiple enemy targets in rapid succession as well as void operations. Their tendency to wear battle damage is a symbol of the Chapter's years of enduring hardship that would've wiped out countless other Chapters; a testament to the endurance of the Mordekaisers.
Mortarchs Serpentia
Vipers Mortis Astartes.png
The Mortarchs Serpentia are a Loyalist Space Marine Chapter of Unknown Founding and origin. These frightful and cryptic marines are not the proud, mythic figures that the Imperium idolises as the Adeptus Astartes, but rather a more horrifying, nightmarish force of power armour-clad spectres. Clad in midnight black and polished bone, they stalk from the darkness and the obscure, their death-rattle cry the only warning the enemy will receive before they are cut down by bolt and blade. Wounds that would lay even the mightiest ogryn low are shrugged off and ignored, the only reaction the enemy receives will be the hollow rattle of the wounded marine, as he continues to crunch forward despite grievous injury.
Mourning Wardens
Mourning Wardens Astartes.png
The Mourning Wardens were created during the 26th Founding as a rare Successor Chapter of the Crimson Fists, who themselves herald from the lineage of the stoic and proud Primarch Rogal Dorn. Even amongst the Scions of Dorn, the Wardens are especially stoic and grim. Their pride expresses itself not in the swing of the blade or cold arrogance but in the calm satisfaction of a unbreakable defense being pierced by their efforts or an indefensible outpost holding out thanks to their presence. However, their stubbornness sometimes costs them to endure unnecessary sacrifices in the course of their duties.
Murdering Sons
Murdering Sons Astartes.png
The 'Homicidialis Filios', more commonly known in the Low-Gothic dialect as the Murdering Sons, are a darkly-famed Space Marine Chapter created with a specific purpose in mind - retribution. This bellicose Chapter was created during the 11th Founding sometime during the dark times of the Nova Terra Interregnum, a period of extreme unrest and civil strife, when the Imperium of Man was split in half, during the early-to-mid M35. When crimes such as insurrection, rebellion or heresy require not simply crushing the guilty, but to exact retribution, the High Lords of Terra deploy the Murdering Sons. These grim warriors are well-suited for the task at hand, displaying a propensity for moral absolution and a drive to enact retribution. The Murdering Sons have utilised the same brutal tactics throughout their millennia of existence, for unexpected violence is their calling card. When they conduct a campaign it is both an unsubtle and bloody affair, but brutally swift.
Myrmidons
Myrmidon Principes Tactical 2.png
The Myrmidons are a Loyalist Successor Chapter created during the 6th Founding from the proud lineage of the heroic Ultramarines. However, unlike their fellow Successor Chapters descended from the lineage of Primarch Roboute Guilliman, known for their noble nature and adherence to the Codex Astartes, the Myrmidons were cut from the same cloth as their progenitors, the darkly-famed Imperius Ravagers. Unlike other Scions of Guilliman, this ancient 3rd Founding Ultramarines Successor Chapter possesses a bellicose nature and brutal mien, and are known for only nominally adhering to the Codex. Inheriting their progenitor's ferocious nature and thirst for war, the Myrmidons have garnered their own brutal reputation for ruthlessly prosecuting the enemies of Mankind, granting them no quarter - only death for their perfidy.

Nemean Lions
Nemean Lions Tact Marine.png
The Nemean Lions are a Loyalist Successor Chapter of the stoic Imperial Fists, raised in M38 during the 23rd 'Sentinel' Founding. Since their inception, the Nemean Lions have steadfastly prosecuted the enemies of Mankind across the width and breadth of the known Galaxy, taking part in many notable conflicts down the millennia. Despite their relative youth, the Nemean Lions have garnered a reputation as highly dedicated and stalwart defenders of the Emperor's domain, and are always eager to answer the call-to-arms should an Imperial world be assailed by heretics, xenos or the malefic. The Nemean Lions always look forward, carving their own legends in the annals of the Imperium's history. Though only a few millennia old, the Chapter has already won many notable victories and earned the approbation of other Adeptus Astartes Chapters and even the High Lords of Terra themselves.
New Dawn
New Dawn Tactical.png
The New Dawn are a Loyalist Successor Chapter created during an Unknown Founding, sometime in late M37, from the proud lineage of the heroic and venerable Blood Angels. Like many of their fellow Chapters of the Blood, the New Dawn have a predilection for close-combat and shock assault tactics. The blood of Sanguinius burns like fire in their veins, and the New Dawn have garnered a reputation as being savage and bloodthirsty in nature. As they are greatly affected by the twin genetic-flaws inherent in their gene-seed, instead of fearing it, the New Dawn embraces these 'flaws' as blessings from the Red Angel.
Night Guard
Night Guard Primaris Intercessor.png
The Night Guard is a Loyalist Chapter, that is shrouded in mystery. Created during the mysterious 13th Founding, the mysterious 'Dark Founding'. Little is known about this obscure Chapter, only when they were created and that they are formidable void warfare specialists and are almost unbeaten in this realm of conflict. They tend to go out in the void in special hardened armour and drift towards an unsuspecting enemy vessel. In this was they can infiltrate the enemy vessel undetected. Other Chapters might find this suicidal, but the Night Guard are masters at doing so. Going out in space without a vessel is their way of war.
Night Ravens
Night Ravens Tact Marine.png
The Night Ravens are a mysterious, if not oft-maligned, Chapter of the Adeptus Astartes, who, despite being labelled as one of the 'sullied' Chapters of the 21st 'Cursed' Founding, has managed to forge a reputation for melding stealth and guile with vigilance, swiftness and perseverance. Like their progenitors, the Raven Guard, these Scions of Corax have become worthy successors as masters in the arts of stealth and speed, raising these skills to near preternatural levels. Developing their expertise over several millennia, the Night Ravens have carved a swathe of blood and ash across the void against the multitude of enemies that have assailed Mankind.
Night Sentinels
Night Sentinels Primaris Intercessor.png
The Night Sentinels is a Loyalist Space Marine Chapter of the Adeptus Astartes and a suspected Successor Chapter of the Salamanders, formed during the Ultima Founding. The chapter is composed of a mix of Primaris (Greyshields and newer recruits) and Firstborn (just under a hundred from different companies of the Salamanders) Space Marines. Their tasking is to protect Imperial interests and, more importantly, Imperial citizens in the Imperium Nihilus, the area of space opposite of Terra of the Great Rift.
Night Terrors
Night Terrors Astartes.png
The Night Terrors are a mysterious and aloof Loyalist Space Marine Chapter created from uncertain lineage and founded during the turmoil of mid-M35. During these times, such as the events of the Nova Terra Interregnum, the Imperium was in a time of disorder and chaos. The Night Terrors were born of such chaos, moulded from the very fabric of disorder and hatred that had torn the Imperium in two. The Astartes of the Night Terrors are more vengeful murderers then soldiers, walking the line between necessary evil and unchained horror. The Chapter quickly gained a reputation as bringers of terror and death, not from every dark corner, but any dark corner.
Night Walkers
Night Walkers Astartes.png
The Night Walkers are a Codex-compliant Space Marine Chapter of Unknown Founding and uncertain lineage. They are based on Morrowdim, a world of the Hadronian Wall in the Aliris Sector. This Chapter has garnered a fearful reputation for their use of terror tactics and psychological warfare against their enemies and have often been the subject of numerous Inquisitorial investigations for committing several massacres.
Nightscream
Nightscream Tactical Marine.png
The Nightscream are a mysterious Successor Chapter created from the lineage of the Raven Guard during the ill-fated and oft-maligned 21st Founding, the so-called 'Cursed Founding', sometime during M36. Like many Chapters created during this Founding, the Nightscream were one of these Chapters affected by the Adeptus Mechanicus' failed attempts at genetic manipulation, which resulted in the Chapter suffering from a debilitating flaw that affects their vision, which rapidly worsens until the affected battle-brother is rent completely blind. However, this unnatural blindness has resulted in them developing far superior senses than even a standard Astartes - superior hearing, an enhanced sense of smell, tastes and acute sensitive touch. Utilising these innate abilities, down the millennia the Nightscream have developed superb expertise in stealth, infiltration and deep strike tactics deep behind enemy lines, committing acts of sabotage, assassination of enemy commanders, and the sowing of destruction and chaos behind the lines mid-battle.
Nova Wolves
Nova Wolves Tact Marine Updated.png
The Nova Wolves Chapter was formed in the 26th Founding from unknown genetic lineage in 739.M41, with the purpose of defending the Imperium from the threats of both xenos and heretics alike. They specialize in void warfare and ship-to-ship boarding actions, but are no slouches on the ground, as they are masters of ranged assaults against the enemies of Mankind.
Night Wyverns
Night Wyverns Intercessor.png
Not a Chapter per se, the Night Wyverns are a Black Dragons kill-team, split from their home Chapter due to their mutations in their Primaris gene-seed. They are officially on record as the first corruption of the Ultima Founding. They display the mutations typical of their predecessors. The Inquisition is want to take offence at the corruption of the gene-seed yet this didn't dissuade the Black Dragon Apothecaries from "improving" the Primaris stock.
Nova Scions
Nova Scions Marine.png
The Nova Scions are an Ultima Founding chapter made entirely of Primaris Space Marines specializing in urban warfare as well as daring Overlord dropship assaults. Although they have often been deployed against traitor Imperial elements and have acquitted themselves loyally and honorably, some of their actions have led the more religious, callous, and fanatical elements of the Imperium, especially the Ecclesiarchy and the Inquisition, to raise questions about the chapter's loyalty, particularly as their background is unclear at best.
Novus Krakens
Novus Krakens Tactical Marine1.png
The Novus Krakens are a Codex-divergent Chapter of Loyalist Space Marines with an unknown progenitor and Founding. Records that were once in the Librarium of the Chapter's Fortress Monastery once contained a wealth of information about the Chapter's actions that suggested it was founded in the 26th Founding. However, the specifics of their founding were lost after the destruction of their Fortress Monastery during 'The Fall of Mobidium', and such knowledge has been permanently lost.

Obsidian Blades
Obsidian Blades Tactical Marine.png
The Obsidian Blades are a Codex-deviant Space Marine Chapter created during the 21st 'Cursed' Founding from Raven Guard gene-stock. Their heritage and gene-seed lineage already leans them towards a more reserved, practical and cunning approach to war, which has only been exacerbated in recent centuries as the Chapter has faced many hardships and near extinctions. The Obsidian Blades believe in ensuring the battle is won before a single shot is fired, sabotaging key structures and poisoning enemy supplies so that when the Obsidian Blades do emerge from the shadows like ghosts, the enemy is already weakened and debilitated. They creep forward under the cover of darkness and stealth, eviscerating lookouts and watchmen silently, utilising combat knives the use of which the Obsidian Blades have perfected.
Obsidian Talons
Mk VII OT Marine With Thunder Hammer.png
The Obsidian Talons are a Loyalist Chapter who - unknown to the vast majority of the Imperium for millennia - were Founded during the 21st (the so-called 'Cursed') Founding. They are often characterised by their aggressiveness, secretiveness, mistrustful nature and their employment bionics on a massive scale. Known for their abilities in exterminating xenos breeds, they predominantly operate on the Eastern Fringe in the untamed areas of space where xenos still run rampant. They are also known to successfully campaign against Tyranid Hive Fleets and splinter fleets thereof.
Omega Knights
OK Mk VII Variant Chest 2.png
The Omega Knights Chapter are a Loyalist, Codex-Compliant Space Marine Chapter that deviates little from it's tenants with the exception to markings on their battle-plate. This Chapter was formed during the 26th Founding in 738.M41, with the purpose of defending the Imperium from the threats of both xenos and heretics alike. It is unknown from whom they first drew gene-seed from.
Omni Legion
Omni Legion Astartes2.png
The Omni Legion is a mysterious Space Marine Chapter created during the 7th Founding sometime in M34 from unknown genetic lineage. Primarily active in the Segmentum Ultima, despite their undying loyalty to the Imperium and its people, the Chapter's history has made the Inquisition suspicious of their very existence. They are primarily known for searching countless systems for traces of technology lost over the millennia. Kept at bay thanks to the influence of the High Lords of Terra and watched closely by an allied Adepta Sororitas Order, this Chapter's gene-seed is strutinised more frequently than normal. But despite this rigorous examination for imperfection or genetic deviancy, they have always passed without fail.
Omniscions
Omniscion Tactical Marine.png
The Omniscions are a Loyalist Codex-compliant Successor Chapter created sometime during M36, during an Unknown Founding, from the lineage of the stoic and unforgiving Iron Hands. Like their genetic forebears, the Omniscions are well known for their fanaticism of the Cult Mechanicus.
Onyx Executioners
Onyx Executioners Colour Scheme Revised.png
The Onyx Executioners are a foreboding and mysterious fleet-based Chapter, supposedly created during the 23rd Founding, the so-called 'Sentinel Founding', from unknown genetic lineage. Originally known as the Crusaders of Glory, this Chapter garnered a reputation as being a humane and pacivistic Chapter that had a reputation for sparing their enemies instead of outright destroying them, often turning them over for interrogation to agents of the Inquisition. However, their merciful nature would prove to be their undoing. In the early decades of M41, a good portion of the Chapter become wholly corrupted by the malefic powers of the Dark Gods, following the capture of a powerful daemonhost. This caused an internecine conflict between the remaining loyalists and Chaos-corrupted brethren, resulting in a full-blown Chapter civil war. After defeating their traitorous brethren, those few loyalist that survived were eventually pardoned and granted the Emperor's forgiveness. To further distance themselves from their treacherous former kin, they changed their heraldry, iconography and Chapter name to the Onyx Executioners.
Ordinators
Ordinators Primaris Intercessor.png
The Ordinators are a 23rd Founding, semi-Codex compliant Space Marine Chapter thought to have been founded by order of the Ordo Malleus to build on the successful practice of Daemonic Possession Therapy to create a specialized anti-Chaos Astartes chapter in a besieged corner of the Imperium. The Ordinators were first mentioned in Administratum records as one of very few Space Marine Chapters with a permanent homeworld within the Segmentum Pacificus in late M38, and are considered by those who know of their presence to have been one of the "Sentinel Chapters" formed to protect the frayed borders of the Imperium In a region which is subject to frequent infiltration by the forces of Chaos.

Paladins of Thunder
Paladin Thunder Primaris.png
The Paladins of Thunder are a semi-Codex compliant chapter created during the Ultima Founding born from the gene-seed of the loyalist Primarch Rogal Dorn of the Imperial Fists. This chapter gained some notoriety during the Indomitus Crusade helping their brothers, the Crimson Fists in their darkest hour alongside them against the daemon incursion of the Daemon Prince Rhaxor and, later, helped a Salamanders Successor Chapter; the Drake Bloods in the desert world of Nimrod. One of the peculiarities of the chapter is that most of their high ranking officials are members of the Apothecarion of the chapter. This is particularly notable with the title that the leader of the chapter bears: Magister Medicae.
Penitent Knights
Penitent Knight CS-Marine.png
The Penitent Knights Chapter is an ancient and fabled Codex-Divergent Chapter with an unknown origination from the 3rd Founding during the early years of M32 bearing an extremely chivalric culture and attitude. The most obvious difference from most other Astartes Chapters is that the Penitent Knights fiercely and zealously believe in defending the citizens of the Imperium, which is backed with a learned ferocity and determination. Often have the honorable Penitent Knights contested with other Imperial forces that civilian life is indeed worthy of protecting, as they point out, was their purpose: to safeguard humanity. To die fighting the abhorrent enemies of Mankind so that defenseless humans may escape death is held in the highest respect among the Knights, second only to do the same and live. Standing defiantly against the forces of Chaos in Segmentum Obscurus for many long millennia has provided them with many opportunities to earn these respects. In possession of the Aegimius System, of the Asteria Sub-sector, very close to the Great Rift created early in M42, the Knights defended their home from frequent Chaos threats, as well as the revelation of their homeworld being a Necron Tomb World. With all of the adversity thrown at them, the Penitent Knights have become nearly depleted, spared destruction thus far by alliances with other Astartes Chapters, and by their own renowned fury.
Penumbral Hydras

The Penumbral Hydras are a Renegade Space Marine Chapter believed to have been born from the conflict known as the Fall of Mobidium. Born from the same genetic template as the Novus Krakens and Leviathans Eclipse Loyalist and Heretic Astartes respectively, the Penumbral Hydras are an extremely secretive Astartes Chapter whom evade catalog by the greater Imperium as much as possible.

Phoenix Brethren
Phoenix Brethren Astartes.png
The Phoenix Brethren are a mysterious Loyalist Space Marine Chapter of unknown origin and uncertain lineage, though rumours abound that they are the remnants of the mysterious Flame Falcons, one of the many Chapters created during the 21st 'Cursed' Founding that were afflicted with rampant mutations. After they began showing signs of a disturbing mutation that caused their bodies to spontaneously burst into flames that did not burn their own flesh, their Chapter homeworld of Lethe was assaulted by the Grey Knights. A small number of Flame Falcons miraculously escaped this dire fate and fled for parts unknown. These surviving Astartes now operate secretly in the thinly-settled Podomos Reach with the tactic support of a few merchant chartists, frontier governors and an equally secretive Adeptus Mechanicus sect.
Pilgrims of Sanctus Penitents

The Pilgrims of Sanctus Penitents are a very small and unique non-Codex compliant Chapter composing of Space Marines from several different Chapters. The Chapter are on a eternal crusade, following the rare Pilgrim-Pattern, traveling to all known Shrine Worlds in the galaxy. Spreading the Imperial Cult throughout the territory of the Imperium.

Thousands of sinners and heretics together with hundreds of fanatic preachers, devoted missionaries and redemptionists follows the Chapter on its crusade through the void.
Platinum Souls
Platinum Souls Primaris Marine.png
The Platinum Souls are a Successor Chapter of the stoic and much vaunted Imperial Fists, created during the notable 23rd 'Sentinel' Founding during the latter part of M37. This Founding was one of a series of linked Foundings that took place during this tumultuous period in Imperial history. They were intended to repair the power and reach of the Adeptus Astartes that had suffered considerable losses in the preceding millennia. Like their forebearers, the Imperial Fists, the Souls are masters of offensive and defensive siegecraft. Unlike the Fists however, they choose to actively seek out siege opportunities and prefer the wars of attrition that come with dense urban fighting.
Polar Flares

Purge Marines Tact Marine.png
The Purge Marines are an elusive and paranoid Chapter of (seemingly loyal) Space Marines created during an Unknown Founding and from uncertain lineage. They are noted for the fact that the Imperium has an astounding lack of information on the Chapter. It is for this reason the wider Imperium remains suspicious of this Chapter. This feeling of suspicion appears to be mutual as the Purge Marines seem to see everyone as a potential Heretic waiting to reveal their treasonous nature. This mutual suspicion has lead to numerous inter-Imperial conflicts. It is suspected that the Chapter's battle doctrine is incredibly violent, viewing the butchering of their enemies as the highest form of religious worship. The Purge Marines display an odd fixation with death and appear to be obsessed with memento mori - artistic or symbolic reminders of the inevitability of death.
The Pure
The Pure Tact Marine.png
The Pure are a semi-Codex compliant loyalist Space Marine Chapter of ancient provenance, created during the 3rd Founding in 001.M32. They are rumored to be a Successor Chapter created from the lineage of the heroic Salamanders. They are known for their selfless attitude on the battlefield, always aiming to save as many civilian lives as possible and to ensure there is no unnecessary collateral damage to a planet's infrastructure, if at all possible.

Quandom Falcons
Quandrom Falcons Vet Marine.png
The Quandom Falcons are a Codex-Divergent Chapter created as a part of the 26th Founding to halt the rising threats to the Imperium that mounted to greater and greater prominence. They are defenders at heart, but will not bow away when called to bring death to the foe. Still appreciative of the effectiveness of a well-planned lightning assault, they make use of plenty of highly mobile units to strike at the weakpoints in the foe's formations. However, more emphasis is focused on the individual melee and martial skill of their Astartes. Prominent in their operations are numerous flocks of cyber-familiars in the shape of the Senshiran Falcon of their homeworld, which they use to gather information before an assault, and intake tactical data mid-battle.

Rebutors
Rebutor Astartes.png
The Rebutors are an ancient, steadfast semi-Codex compliant Space Marine Chapter created during the 4th Founding, following the aftermath of the infamous War of the Beast in the mid 500's.M32. The Chapter is extremely honorbound, devoted heavily to carrying out tasks and enacting campaigns in honorable manners. Unlike most other Astartes Chapters, the Rebutors value the lives of Imperial citizens, frequently defending them against various threats. This system of belief has earned the Chapter many a disapproval from other Space Marine Chapters of the Imperium, those being more heartless. Similar to that of the Black Templars Chapter, the Rebutors are currently in a Crusade that demands the demise of all aliens and heretics that seek to disturb the might of the Imperium. However, unlike their Black Templars gene-brethren, they are far less extreme and zealous.
Reclaimers of Dorn
ReclaimersOfDornIntercessor.png
The Reclaimers of Dorn are a successor chapter of the Imperial Fists. They were among the Primaris Space Marine Chapters created during the Ultima Founding, at the direct order of Roboute Guilliman, and were created during the Indomitus Crusade. Unlike their progenitors, the Reclaimers have a predilection for engaging the foe at close quarters rather than long, drawn-out sieges. This Chapter has taken to the stars to seek out their long lost gene-sire, believing the Imperium can only be truly saved through the strength and leadership of Dorn. Though the Chapter's primary objective is to locate their own progenitor, the Reclaimers will pursue any lead that leads them to any missing Primarch, both loyalist and traitor.
Red Crusaders
Red Crusaders Astartes.png
The Red Crusaders are a loyalist Space Marine Chapter created during the 4th Founding during the middle centuries of M32 from unknown lineage. This Chapter hails from the Sanctus System, a star system currently lost to the Imperium Nihilus due to the destruction of Cadia and the Cicatrix Maledictum. Like the Black Templars, the Red Crusaders also believe in the divinity of the Emperor, though the question of if its really the Emperor they worship has been brought up many times by Inquisitors.
Redeemers
VW Intercessor.png
The Redeemers is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the rare lineage of the Raven Guard and raised during the Ultima Founding of ca. 999.M41. Created as a chapter to watch potential new threats coming from outside the Milkyway Galaxy, the Void Watchers keep their eyes in any events enveloping the Eastern Fringe. Their actions usually take them against both Ork forces and Tyranids.
Retributors
Retributors Impulsor Marine.png
The Retributors are a Successor Chapter of the Imperial Fists of an unknown Founding. Described as distant, relentless and efficient by those fighting alongside them, the Retributors are a stern and austere Chapter, more interested in tactical success than battlefield glory. Despite playing vital roles in several campaigns, these endeavors tended to be drowned out in Imperial archives due to their lack of self-promotion. Despite this, the High Lords of Terra and astute Imperial commanders were well aware of the Retributors capabilities and their assistance was always in demand. Of particular note is their significant cooperation with Inquisitorial lead operations throughout their history.
Reverent Crusaders
Mk III Reverent Crusaders Marine.png
The Reverent Crusaders are a Loyalist Successor Chapter of the ancient and mysterious Dark Angels, and are thus, one of many Successor Chapters that hail from the lineage of Lion El'Jonson, collectively known as the Unforgiven. This Chapter was created during the 4th Founding in the wake of the near disastrous War of the Beast, which left the Chapters of the Adeptus Astartes devastated. Since that time, they've continued to serve as stalwart defenders of the Imperium of Man.
Ruby Sabres

Pict-File Unavailable

The Ruby Sabres are a formerly Loyalist Space Marine Chapter created during the 15th Founding from unknown lineage. The Chapter was known for its close adherence to the Codex Astartes. They defended the Imperium from the countless enemies of Mankind for centuries. Yet one battle-brother would soon make a grave mistake on the world of Thesulia Prime. Now they fight against the Imperium, against those they once swore to protect. They were eventually cast out of the Imperium and declared as renegades and became the notorious Chaos Warband known as the Bloody Hands. A large number of Alpha Legion have found their way into the warband, which the Bloody Hands have accepted with excitement, for any opportunity to sabotage the Imperium that the Alpha Legion uses, the Bloody Hands are glad to assist in

The Ruiners are a semi-Codex compliant Space Marine Chapter of the Adeptus Astartes comprised entirely of newly revealed Primaris Space Marines created during the Ultima Founding. They bear the gene-seed of Primarch Ferrus Manus of the grim and unforgiving Iron Hands. While this Chapter does maintain their parent Chapter's close ties with the Adeptus Mechanicus, they do not share in their beliefs in the weakness of the flesh.

Sable Lions
Sable Lions Rafiq.png
The Sable Lions are a Successor Chapter from the line of Rogal Dorn, supposedly created during the 8th Founding, which allegedly occurred during mid-M34. This Founding was undertaken amid the dark times of the Nova Terra Interregnum, when the Imperium of Man had been split into twin interstellar empires. The Sable Lions quickly garnered a noble if aloof reputation, even for the warriors of the Adeptus Astartes. For their role during this conflict, they were given the primitive world of Persepolis, located in the galactic north near the Pelegron Cluster, which lies near the edges of the Segmentum Ultima and the Segmuntum Obscurus. They serve as protectors, guarding the Imperial routes to the Forge World of Mezoa, located in the nearby Gothic Sector, while their Chapter starships tirelessly ply the borders of the Pelegron Cluster, hunting down and slaughtering xenos corsairs and potential Chaos incursions that have long made this trackless region their lair.
Sanctors of Lightrim
Sanctors of Lightrim 2.png
The Sanctors of Lightrim were a formerly Loyalist Space Marine Chapter created during an Unknown Founding and of uncertain lineage. They were founded to guard against the threat of the Traitor Legions attacking the Nosgothica Sector from the nearby Eye of Terror. The Sanctors were once counted amongst the most stalwart defenders of mankind. But the insidious threat of Chaos wrapped its corrupting tendrils around the very soul of the Chapter, instilling within the Sanctors' lore-seeking brethren, an unnatural craving for forbidden knowledge. Believing they could defeat Chaos by utilising the power of the Ruinous Power against itself, they were eventually declared renegade and driven into the Eye of Terror, becoming the Chaos Warband known as the Sons of Damnation.

Sanguine Berzerkers
Sanguine Berzerker Oxrekkr Tactical.png
The Sanguine Berzerkers are a Loyalist Successor Chapter created from the lineage of Sanguinius and his noble Blood Angels. An ancient and laudable Chapter, the Sanguine Berzekers claim to one of several Chapter created during the Second Founding in 021.M31, following the successful conclusion of the Great Scouring. However, due to the paucity of records, human error and the passage of time, these claims cannot be accurately verified. Following their inception, the Sanguine Berzekers quickly established themselves as a bellicose and savager Chapter, forever prosecuting their neverending war against the enemies of Mankind. But the Sanguine Berzerkers have also garnered a reputation as one of the more savage Chapters of Blood Angels' lineage, for like their Progenitors, the Chapter has a penchant for close-quarters combat and makes heavy use of assault units within their Chapter formations.
Sanguine Chalice
Sanguine Chalice Primaris Intercessor.png
The Sanguine Chalice are a Loyalist Successor Chapter of the vaunted and heroic Blood Angels. Created during an unknown Founding, despite being unable to pinpoint exactly when they were created, it is well known that they possess a long and glorious history, having been pivotal in many victories against the Chaotic horrors that have emerged from the infamous warp rift known as the Eye of Terror. During the recent Devastation of Baal, the Chapter valiantly faced the ravenous hordes of the Great Devourer and were wiped out to a man. However, with the advent of the Ultima Founding and revelation of the new Primaris Space Marines, this Chapter was re-constituted with this next generation of Astartes. They continue to honour both their Progenitors and their namesake through their heroic deeds.
Sanguine Spectres
Sanguine Spectres Tact Marine.png
The Sanguine Spectres are a Successor Chapter of the noble Blood Angels, created during the 25th 'Bastion' Founding, which occurred during the latter half of M40. They suffered heavy losses during the Devastation of Baal campaign against the Tyranids of Hive Fleet Leviathan, losing their Chapter Master and several companies, including the 1st, 5th and 6th and companies.
Sanguine Templars
Sanguine Templars Tactical Marine.png
The Sanguine Templars are a venerable and ancient Successors Chapter of the sacred bloodline of the angelic Primarch Sanguinius, gene-sire of the the heroic Blood Angels, created during the Second Founding in 021.M31. Formerly, they were known as the 7th Company of the original IX Legion. The warriors of this company were known to revere the Great Angel above all else, which bordered on worship. Despite the tenants of the non-secular Imperial Truth that was enforced upon newly conquered worlds. However, their resolve was sorely tested during the dark days of the Horus Heresy, when the galaxy was torn asunder, following the subsequent betrayal of the Emperor's most favoured son. Following the end of the Horus Heresy and the subsequent Great Scouring, the Space Marine Legions were sundered into separate Chapters. Recognised for their stalwart and dedicated service, the 7th were granted the honour of forming their own Chapter - the Sanguine Templars. Following their inception, they immediately departed Terra, vowing to undertake a perpetual Crusade, in order to bring the light of the Emperor to the darkest corners of the galaxy.
Sea Serpents
Sea Serpent Tactical Marine.png
The Sea Serpents are a non-Codex compliant Chapter of Space Marines whose exact Founding and lineage are unknown, although some Imperial scholars hypothesize their origins harken back to the dark days of the Horus Heresy to a similarly named Loyalist Blackshield force. Known for their use of terror tactics, infiltration and asymmetrical combat strategies, they've made a name for themselves as a fearsome and elusive tool of the Imperium that swiftly destroys their enemies before they can even mount a defense.
Seraphim of the Abyss
GK MK VII Armor With Bolter Wolf Pelt.png
The Seraphim of the Abyss are a mysterious and ancient semi-Codex Compliant Dark Angels Successor Chapter from the 2nd Founding, and thus members of the Unforgiven, Scions of the Lion that hunt the Fallen Angels. Once, the Chapter was named the "Seraphim of the Gryphon" until tragedy struck these sons of the Lion when their beloved home-world was destroyed, like Caliban of old, and now restlessly engage in the Hunt for the Fallen. They also have developed their own distinct culture and beliefs over the millennia inhabiting the planet that was once heralded as a "New Caliban." Due to the specialties of the Boletarian recruits uplifted to the Chapter, the Seraphim have developed either a love or a deep appreciation for hunting, whether it be the traitorous Fallen or a particularly deadly xenos species. However, their own separate cultural traditions have created a chasm of animosity between them and their fellow Unforgiven Chapters.
Seraphs Sanguine
Seraphs Sanguine Sergeant.png
The Seraphs Sanguine are a Loyalist Successor Chapter of the Adeptus Astartes that were created during the 20th Founding from the heroic lineage of the First Founding Blood Angels. Their fortress-monastery 'The Shard' is located on the glassy desert death world of Agrito.
Sermo Invictus
Sermo Invictous Mk VII Variant Armour.png
The Sermo Invictous Chapter is a Loyalist, non-Codex compliant Space Marine Chapter drawn from unknown lineage and created during an unknown Founding, though their Founding could have been no later than the 3rd Founding due to their appearance in the War of the Beast in 544.M32. Many believe the Chapter is a fervent offshoot of the already zealous Black Templars, while others believe there is a darker past to this Chapter's origins, possibly making them related to the hated Word Bearers Traitor Legion.
Shadow Phantoms
Shadow Phantoms Astartes.png
The Shadow Phantoms are a Loyalist Space Marine Chapter created during the mysterious 13th Founding, to so-called 'Dark Founding'. Their origins are unknown, though there is reason to believe that they are descendants of the mysterious chapter, Zero Legion. Once they were known as the Shadow Knights, but following the near destruction of the chapter, they've changed their Chapter name and ways. The Chapter is also known to offer their services to Inquisitor Alexander Zackery, and have been well respected by the various Imperial Guard Regiments they have worked alongside with.
Shadow Talons
Shadow Talons Tact Marine.png
The Shadow Talons are a 4th Founding Successor Chapter of the heroic Raven Guard, created sometime in the fifth century of M32. Little is known about this Chapter in official Imperial records save that the Shadow Talons are known to be a reclusive and suspicious Chapter, who no longer trust other Space Marine Chapters or the Imperial government, preferring to work alone and unobserved by all, save the foes of Mankind and the Emperor.
Shadow Warriors
Shadow Warriors Tactical Marine.png
The Shadow Warriors are a brutal Raven Guard Successor Chapter that was created during the 24th Founding, sometime in early M38. Hailing from the verdant jungle world of Rehua I, located in the Ultima Segmentum, the Shadow Warriors have been ranked among the most brutal and fearsome of the Raven Guard Successors. Inheriting their strategic prowess from the Raven Guard, the Shadow Warriors combine vicious assaults with cunning tactics and guerrilla warfare, exploiting the enemy's weak spots with lightning fast deployment and finishing them off with brutal efficiency. While these marines inherit the logistical aspect of their battlefield doctrine from the Raven Guard, they carry on the violent and cunning traditions of the tribes of their home world. Many observers often remark on the terrible suffering they bring to their enemies, utilizing close combat brutality to tear apart xenos and heretic alike.
Shadow Wolves
SW Intercessor.png
The Shadow Wolves are a newly reconstituted Successor Chapter, comprised entirely of Primaris Space Marines. This Chapter was created from various gene-seed of Primaris Space Marines that made up the ranks of the Unnumbered Sons, which were derived from various Chapters whose genetic lineage hailed from the stoic and proud Imperial Fists. In their original iteration, the Shadow Wolves were a proud Successor Chapter, created during an Unknown Founding, that were also created from the lineage of the Imperial Fists' Primarch Rogal Dorn. Unfortunately, their long and glorious history would end in tragedy in 987.M41, when their Chapter homeworld of Varadon was overrun by the foul xenos bioforms of the ravenous Tyranids.
Shattered Star
Shattered Star Astartes.png
The Shattered Star are a Loyalist Space Marine Chapter believed to have been created from unknown lineage during the 21st Founding, the so-called 'Cursed' Founding sometime during M36. Despite the rampant mutations or various idiosyncrasies that inevitably affected most of the Chapters created during this Founding, the Shattered Star's gene-seed remains relatively unaffected by these genetic curses that plague their 'Cursed' Founding brother Chapters.
Shields of the Void
SoV Aquila Battle-Dmg.png
The Shields of the Void are a loyalist semi Codex-compliant Successor Chapter created from the lineage of the proud but brutal Iron Hands Space Marine Chapter during the 4th Founding. This Founding occurred following the events of the near-disastrous War of the Beast which laid waste to the galaxy and had even threatened the security of Terra itself.
Silver Centurions
Silver Centurion Astartes.png
The Silver Centurions are a loyalist Codex-compliant Successor Chapter that hails from the proud lineage of the honorable Ultramarines. This Chapter was supposedly created during the mysterious 13th Founding (known also as the 'Dark' Founding), under commendation of the High Lords of Terra and Chapter Master Ollonius of the Ultramarines, following a successful campaign to restore the Euridite Sector at the edge of Segmentum Tempestus. This highly organised Chapter is known to recruit their members on both Penal and Hive Worlds across the Segmentum Tempestus, picking troubled youths and young hive scum gangers to become Angels of Death. The Silver Centurions are a fleet-based Chapter who continuously patrol across the width and breadth of the galaxy, to take the fight to the enemies of mankind before they become a dire threat.
Silver Fists
Silver Fists Primaris.png
The Silver Fists are a Chapter formed of Primaris Space Marines created from Rogal Dorn's gene-seed, who served as part of Roboute Guilliman's Unnumbered Sons during the Indomitus Crusade. After the Avenging Sons's Crusade ended, the Silver Fists were formed and relocated to Sebastus VI, were they began recruiting and strengthening their numbers. Having studied the tactics of the Imperial Fists, the Crimson Fists and even the Black Templars chapters that were available, they began to develop their own strategies to intervene in both xenos and traitor attacks on populated worlds and valuable locations.
Silver Shards
Silver Shard Battleline Marine.png
The Silver Shards are a Loyalist Space Marine Chapter descended from the Primarch Rogal Dorn and successors to the honourable and proud Imperial Fists Chapter, with their founding being held during the 4th Founding in the 500s.M32. Currently, the Silver Shards are a fleet-based Chapter, with its main operation being in northern Segmentum Ultima, however, several crusades have been declared prior and presently that took the Chapter into the Eastern Fringe and Segmentum Obscurus, where the ruins of their homeworld reside.
Silverbacks
Silverbacks Ghekrunanse.png
The Silverbacks are a Loyalist Space Marine Chapter of unknown Founding and lineage. It is believed that they were created during the 9th Founding. Their fortress-monastery is located on the jungle Death World of Wazari II between the borders of the Segmentum Obscurus and Segmentum Pacificus. The Astartes of this Chapter are notable for being unusually large and robust physical specimens, even amongst their kind, and they are capable of surviving wounds and physical injuries that would kill even other Space Marines. Very little information is recorded about this Chapter in official Imperial records.
Sin Eaters
Sin eater marine.jpg
The Sin Eaters are a non-Codex complient chapter of Successor Chapter of the ancient and honourable Blood Angels, created during an Unknown Founding. They are noted as a highly superstitious chapter, holding the curses of Sanguinius's gene-seed with religious reverence. It is their belief that, by interpreting the mad ravings of those afflicted with the Black Rage, the chapter can glean insights into the lingering grace and wisdom of their primarch.
Sin Seekers
Sin Seekers Tactical Marine.png
The Sin Seekers are a Loyalist Space Marine Chapter of unknown lineage, produced somewhere around the 19th Founding. They are highly proficient hunters of Heretic Astartes within the ranks of the Adeptus Astartes, tracking their fallen cousins across the galaxy and ending them justly. Their unending-crusade of seeking their quarry far outweighs assisting their fellow Loyalist Chapters, making them disliked by most Chapters aware of their existence.
Skull Reapers
Skull Reapers Astartes.png
The Skull Reapers are an Astartes Chapter of suspected Iron Hands descent created during an unknown Founding, but are suspected to be a Chapter of the mysterious 21st Founding, the so-called 'Cursed Founding', as they are extremely similar in appearance to the mysterious Sons of Antaeus Chapter. The Astartes of the Skull Reapers Chapter are unusually large and robust physical specimens, even among their kind, and they are capable of surviving wounds and physical injuries that would kill even other Space Marines. The Chapter's detractors point out that the Skull Reapers appear every bit as resilient as the Death Guard Traitor Legion and some have even opinioned that they are somehow connected to them, but this is an impossibility as the Skull Reapers were created thousands of years after the Horus Heresy and have, on many occasions, willingly submitted themselves to the mandatory purity tests of their gene-seed which has seemingly confirmed their status as an Iron Hands Successor Chapter.
Smilodons
Smilodons Tact Marine.png
The Smilodons are a loyalist non-Codex compliant Space Marine Successor Chapter created from the lineage of the proud and feared White Scars of a Unstated Founding in M36. The Chapter was created during the appalling period called the Reign of Blood, when the Renegade High Lord of Terra Goge Vandire gained control over the Adeptus Ministorum, Adeptus Administratum and became the Ecclesiarch. This resulted in massive purges and assassinations of countless of innocent Imperial citizens. In the end, Goge Vandire was executed for his crimes against the Emperor and the Mankind, by the Daughters of the Emperor Matriarch Alicia Dominica.
Soaring Chalice
Soaring Challice.png
The Soaring Chalice are a former Loyalist Space Marine Chapter, originating from the Blood Angels and currently known as the Foetid Seraphim Chaos Warband after turning to Chaos during late M37. The Foetid Seraphim worship the Chaos God Nurgle and thus most of the members are hideiously deformed and riddled with disease. Currently they mainly utilise shock tactics in order to win battles, deploying their infamous Blight Bringers and Butchers of Atrophy in order to break their enemies morale. Currently, they roam the galaxy almost aimlessly, leaving rotting husks of the planets they visit.

Solar Falcons
Solar Falcons Veteran Marine.png
The Solar Falcons are a venerable Successor Chapter created from the lineage of the wild and unforgiving White Scars during the Third Founding in 001.M32. The initial members were drawn from the few surviving Terran-born Astartes. To this day they still recruit from the continent of Europa but keep there Fortress-Monastery elsewhere on a small planet in the Segmentum Solar. This Chapter is mostly utilised to explore and subjugate unexplored parts of space, bringing any human empires into Imperial compliance and wiping out all xenos found. They are known for having an overly savage nature for warfare and for there strict adherence to the Imperial Creed compared to most other Adeptus Astartes Chapters. Both were born from being deployed alongside the crusading Black Templars during an early chapter-wide assault on an unnamed Chaos-held world.
Solar Phoenixes
Solar Phoenixes Firstborn.png
The Solar Phoenixes are a Space Marine Chapter of unknown origin. Records indicate they were likely created during the 21st Founding , or the 'Cursed Founding'. While only being slightly larger than the average Firstborn Space Marine, they are somewhat stronger and are able to match their Primaris counterparts under certain circumstances due to mutations in various organs. They largely act as defensive force in the Segementum Tempestus, operating out of the their Chapter home-world of Argentus Tempest. They frequently aid Imperial planets against xenos and chaotic incursions, burning the invaders to ashes. In battle, they are known for their Skyfire and Infernus doctrines, where they use flame and melta weaponry alongside aerial superiority and drop-pod assaults to deadly effect.
Solar Spectres
Solar Spectres Primaris Intercessor.png
The Solar Spectres are a mysterious and merciless Space Marine Chapter created during the recent Ultima Founding. Created from the lineage of the wild and untamed White Scars, this Chapter is comprised entirely of newly revealed Primaris Space Marines. Like their progenitors, the Solar Spectres continuously roam the galaxy, stalking the various battlefields across various warzones, delivering swift and brutal death to those that would dare assail the worlds of the Emperor.
Solar Titans
Solar Titans Intercessor.png
The Solar Titans are a Codex Astartes-compliant Chapter created during the recent Ultima Founding at the ending of the Indomitus Crusade. They descend from the lineage of the stoic Primarch Rogal Dorn and, as such, are not particularly known to withdraw from battle, due to their stubbornness. These noble soldiers are settled in the feral world of Palyphomas, the fifth planet of the Centurion System, located in the Ultima Segmentum. The mostly jungle world borders the far end of the T'au Empire, a fact that, coupled with its rich mineral and biochemical resources, make its defense highly desirable.
Solar Wardens
Solar Wardens Astartes.png
The Solar Wardens are a 25th Founding loyalist chapter of the Adeptus Astartes, and the sole Successor Chapter of the Hammer Guard. They follow a unique organisation, casting aside the Codex Astartes. Originating from the planet Mhuir, the chapter has been given the Mhuir system to recruit from, as their homeworld is uninhabited. Instead they recruit from Mhuir II, known as Coille by the inhabitants. The chapter's progenitor, their chapter cult and gene-seed have all created conflict with the Inquisition. Despite being bloody and savage warriors, the Solar Wardens have an artist's side, constantly modifying their armour and creating fine works of art to honour their chapter cult.
Solar Wolves
Solar Wolves Tact Marine.png
The Solar Wolves are an Astartes Chapter of Unknown Founding and descent but speculation is that they are one of the unrecorded Second Founding Chapters, as they are noted to have fought during the Teclis Campaign during M32. They are a semi-Codex chapter in that they follow many of the tenets laid down by the Primarch Roboute Guilliman but are not bound to it as many are, rather it is a guide to be added to or ignored as the situation warrants. They do not follow any one particular combat doctrine but rather strive to excel at any battle they are called upon to fight.
Sons of Iron
SoI Astartes.png
The Sons of Iron Chapter is a 26th Founding Successor Chapter of the Iron Hands. Hailing from the perilous world of Suami, the Sons have begun to gain a reputation, among the kin of Ferrus Manus, as an effective Chapter, whose sole and yet infamous stain is their beliefs tantamount to heresy in the eyes of the Iron Hands and many of their successors, while the Imperium at large consider them as a cold and unforgiving gathering of devoted Space Marines, exemplifying the better traits from their Progenitor without the strained relationships which are often the lot of Ferrus Manus lineage. Like all those who bear the Seed of Manus, they feel the drive to replace their flesh with bionics, but try to resist it, a strain which adds to their already grim demeanour.
Sons of Neptune
Sons Neptune Tact Marine.png
The Sons of Neptune are a Succesor Chapter of the White Scars, created during the 23rd 'Sentinel' Founding. A Chapter that feels as at home in the vastness of the Void, as they do on the waves, they are known for their swift assaults, crashing against enemy forces like an unrelenting tsunami, pushing until their mission is complete and washing all aside to complete their objectives.
Sons of Odin
Sons Odin Tactical Marine Mk IV.png
The Sons of Odin are a Loyalist Successor Chapter believed to have been created during the 3rd Founding in 001.M32. The Astartes of this Chapter are the proud scions of Roboute Guilliman, the Primarch of the Ultramarines. Though they share little in common with their forebears' culture and traditions, they have garnered a reputation for their unbreakable sense of honour and a history of unparalleled skill at arms. In battle, their ferocious mien has often seen them carry the day, when all odds have been stacked against them. The Sons of Odin are unafraid of battles of attrition or mutual destruction, relying on the abilities of their Battle-Brothers to overcome and endure anything the enemy can throw at them. At times this has proven to be a flaw, as the Chapter has a predilection to fight on once engaged where its better strategic judgment might have otherwise prevailed before its bloodlust was roused.
Sons Sanguine
Sons Sanguine Astartes.png
The Sons Sanguine are a Codex-compliant Successor Chapter of the Angels Sanguine created during the ill-fated 21st 'Cursed' Founding. As inheritors of the lineage of the angelic Primarch Sanguinius, the Sons Sanguine have also inherited the twin genetic flaws which linger over their Chapter like a shadow. Though they possess a enviable history of heroism and valour, rumours and unease surround them. Like their genetic forbears, the Angels Sanguine, the Sons Sanguine also shield their faces from those they fight alongside. They also possess a higher number of Librarians than normal.
Sons of the Creed
SoC Mk VII Tactical Marine Final.png
The Sons of the Creed are a Codex-compliant Chapter created during an Unknown Founding from the lineage of what is usually assumed to be that of the vaunted Ultramarines. This assumption is due to both their astrographical closeness to Ultramar as well as the numerous occasions down the millennia they have fought alongside the Scions of Guilliman. A lauded and honorable Chapter, the Sons of the Creed have fought the foes of Mankind since at least M33, standing as a bulwark against the myriad of threats that assail the Imperium, both from without and within.
Sons of the Emperor
Sons of the Emperor Mk VI Tact Marine.png
The Sons of The Emperor are a Codex Astartes-compliant Chapter that is currently engaging in a 100 year-long Penitent Crusade to pay for their past sins. They are followed vigilantly by the Crystal Dragons Chapter, responsible for supervising these golden Astartes. Although the crusade is almost over, the Sons' numbers are rapidly decaying and, without the coming of new recruits, this proud chapter may not see their reputation cleansed.
Soul Flayers

Pict-File Unavailable

The Soul Flayers Chapter is a loyalist Successor Chapter created from the heroic lineage of the ancient Blood Angels - founded during the ill-fated 21st 'Cursed' Founding. Like many Chapters born from the largest Founding of Space Marine Chapters since the Second Founding, the Soul Flayers are plauged with identified deficiencies in their gene-seed. Like their forebears, the Chapter is heavily fundamental in their beliefs of their Primarch, however, the Chapter views the "Flaw of Sanguinius" as a gift from the Emperor himself and sees it as a way to enter into the Imperium's Pantheon as an ordained saint. This has made the Chapter renowned for shock troop tactics, with their reliance of brute force and terror tactics by the hands of their Black Enraged Brethren.
Soul Wardens
Soul Wardens.png
The Soul Wardens are a Loyalist Successor Chapter of the brutal and merciless Executioners Chapter, themselves a descendant of the vaunted Imperial Fists, created during the 22nd Founding to help prosecute the Great Cull. After their admirable and zealous conduct in the Great Cull, the High Lords of Terra gifted them a mighty war fleet, and the Soul Wardens promptly set sail amongst the stars as a Crusading Chapter. The Soul Wardens have long venerated the time of the Great Crusade, and the original beliefs and mission of the Emperor. They have taken it upon themselves to uphold those tenets and to never cease in fighting to restore the Imperium to its former glory. Although they are successors of the Executioners Chapter and long maintained close contacts with their primogenitors, after the events of the Badab War, the Soul Wardens have largely broken off contact with their genetic forebears. Instead, they have pledged new oaths of brotherhood to the Imperial Fists as sons of Rogal Dorn.
Space Naga
Space Naga Astartes.png
The Space Naga are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the vaunted Ultramarines during the 23rd Founding, known as the 'Sentinel Founding'. They were created under the dispensation of the High Lords of Terra as a Successor Chapter of the well-organized and highly venerated Scions of Guilliman in order to fulfill the additional defence of the Eastern Fringe against both the Forces of Chaos from the Warp anomaly known as the Maelstorm, the emergent Tau Empire, the tendrils of encroaching Hive Fleets, and marauding Ork WAAAGH! fleets. Under commendation from the Ultramarines' Chapter Master Marneus Augustus Calgar, the Space Naga was given control of the system known as the Indravari System, a system consisting of three planets. The Chapter has become widely known for their formidable psychic defence veil, known as the 'Gautam Veil', that protects the Indravari System from invading xenos or Chaos alike. The Space Naga are also known for their extensive use of psyker-infused melee weaponry which is capable of absorbing souls of daemonic entities, as well as possessing a large quantity of grav weaponry - from the simple grav pistol to the long lost Horus Heresy technology of the mobile platform, Rapier grav cannon.
Spartiate Marines
Spartiate Marine Astartes.png

Spectral Wolves
Spectral Wolves Astartes.png
The Spectral Wolves are non-Codex adherent Chapter that was created from the lineage of the sons of Russ Unlike other Chapters, the Spectral Wolves do not possess the usual number of 1,000 battle-brothers, instead numbering around 300. Despite their smaller size, the Chapter's ferocity and stubbornness in the face of overwhelming odds, more than makes up for what they lack in numbers. The Chapter, referred to as the Shadow Company by their Chapter Master, Wolf Commander Tyr Hjalmar, are known for one of the earliest discoveries of the Tyranids beyond the borders of the Eastern Fringe, and were one of the first Chapters to warn the Imperium about the coming of an extra-galactic composite species of hideous xenos, that was in actually, a space-faring ecosystem comprised of innumerable different bioforms comprised of innumerable variations on the same genetic theme - the Tyranids. This Chapter is known for possessing an inordinate amount of power weapons compared to most other Adeptus Astartes Chapters.
Star Angels
Star Angels Astartes.png
The Star Angels are a Loyalist chapter of Space Marines that are suspected to have been created in the 23rd 'Sentinel' Founding, of an unknown lineage. Their fortress-monastery 'The Hallowed Star' is located on the arid desert Feral World of Indeius. They are unusual in that a Chaplain may rise to the rank of Chapter Master (referred to as High Chaplains), most notably being Morterus, who led the chapter in their ill-fated crusade across the Caligari Sector.
Star Crusaders
Star Crusaders Tact Marine.png
The Star Crusaders are a relative young Loyalist Space Marine Chapter founded in M39 during the 24th Founding as a fleet-based Chapter to conduct space warfare, low/zero-g combat as well as a rapid response against enemy fleets who were able to penetrate deep into the Imperium.

Such an attack was the example why the Chapter had been formed and currently is engaged with the remaining part of this hive fleet.
Star Golems
Star Golems Primaris Intercessor.png
The Star Golems are a Loyalist Space Marine Chapter of the Adeptus Astartes and rare Successor Chapter of the ancient and proud Salamanders. Since their very founding, many of these former Salamanders have held the high opinion of the Adeptus Mechanicus and their feats, believing like most of the Imperium that the Omnissiah and the Emperor are the same entity. They seek to recover the God-Emperor's holy machines, spending much of their time scouring ancient battlefields and wreckage for a shred of relic archeotech.
Star Knights
Star Knights Astartes.png
The Star Knights are a 4th Founding Chapter, descended from the Ultramarines. Well known for being masters of tracking and ambushes, the Star Knights were originally a Codex-compliant Chapter until the Age of Apostasy, when their original homeworld, Artemis, was destroyed by both Chaos incursions and Imperial forces loyal to Goge Vandire, which left the chapter very undermanned to the point of extinction. After the tyrant’s death and the coming of Sebastian Thor, the chapter was cleared of all charges and made another world, the largely populated planet of Garo, their new home. Now the Star Knights have been hailed as some of the greatest hunter and trappers - Space Marines able to hunt down and perfectly counter the foes of man.
Star Reapers
Star Reapers Tact Marine 2.png
The Star Reapers are a foreboding Space Marine Chapter founded at an unknown date and are suspected successors of the venerable Raven Guard. They are a highly controversial and isolationist chapter, with a history of ruthless brutality. This Adeptus Astartes are experts of lightning fast manoeuvres planned with a detailed complexity unseen in most Space Marine doctrine. Cloaked in a shroud of deliberate mystery and concealment likely created by agents of the Star Reapers themselves, the Chapter hides itself from the prying eyes of institutes such as the Inquisition and even other Chapters considered allies. Indeed, the only beings that know every secret of the Chapter are it's master and the Emperor Himself.
Star Wardens
Star Wardens Bolter Updated.png
The Star Wardens are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, that was originally created during the 4th Founding in mid-M32. In the final dark days of M41, the Star Wardens were trapped when the Cicatrix Maledictum, otherwise known as the Great Rift, opened while the chapter was undertaking a defense of the Hydraxa System from Hive Fleet Basilisk. Locked into a desperate struggle to save both the human inhabitants of the system and the legacy of the chapter, they were reduced to a mere handful of marines before the timely arrival of Roboute Guilliman and the Indomitus Crusade.
Steel Crusaders
Steel Crusaders Astartes.png
The Steel Crusaders are an 8th Founding Successor Chapter of the stoic Iron Hands. Like their progenitors, the Steel Crusaders heavily augment themselves with numerous bionics.

With their mighty war-machines the Steel Crusaders bring utter ruin upon the enemies of Mankind.
Steel Harbingers
Steel Harbinger Mk VII Variant Armour.png
The Steel Harbingers are an ancient and venerable Space Marine Chapter created during the 3rd Founding at the dawning of M32. This Founding took place following the tragic era of the Age of Darkness during the Horus Heresy, the subsequent Great Scouring and the sundering of the Legiones Astartes into separate Chapters. It is unknown with any certainty from whom this Chapter is descended from, but many of their cultural beliefs and propensity for utilizing bionics mirrors that of the the stoic and unforgiving Iron Hands, though these Sons of the Gorgon refuse to acknowledge the Steel Harbingers as one of their own.
Steel Hart
Steel Hart Astartes.png
The Steel Hart are a strictly Codex-compliant Astartes Chapter, officially of Ultramarines descent. However, in reality, they are actually descended from Iron Warriors' stock. Originating from the 3rd Founding, the Steel Hart are deeply loyal to the God-Emperor of Mankind and the eradication of His enemies, and have amassed an exemplary record in this regard. However, the Steel Hart have at times shown a disturbing and callous disregard for their own lives as long as their mission objectives are achieved. This cavalier attitude has often carried over to their auxiliaries or allies, each burdening heavy casualties alongside the Astartes Chapter.
Steel Kindred
SK Brother.png
The Steel Kindred are a semi-Codex Compliant Chapter created in the Ultima Founding descended from the stoic Iron Hands. They are bound by their pragmatic logic that sees them carry out well calculated plans with efficient zeal and augment their weapons, armour and bodies with cybernetic augmentations.

Steel Sentinels
Steel Sentinels Cutout.png
The Steel Sentinels are a Successor Chapter of the heroic Ultramarines, created during the recent Ultima Founding, after the Unnumbered Sons were broken up into separate chapters.

Steel Tempests
Steel Tempest Mk VII Variant Armour.png
The Steel Tempests are a 25th 'Bastion' Founding successor chapter hailing from the lineage of the Iron Hands. Well known for their discipline and professionalism, as well as their characteristic scathing wit and remarkably casual Chapter culture (most unusual for a Chapter descended from Ferrus Manus), the Steel Tempests have been led by Chapter Master Rainald for almost two centuries
Steel Tigers
Steel Tigers Tact Marine.png
The Steel Tigers are a Successor Chapter of the Adeptus Astartes, with their lineage drawn from the White Scars and founded in the year 862.M37 as part of the 23rd Founding. The Chapter finds its home in the Kassari System, with its homeworld being the Hive World of Kassari Primus although its Fortress-Monastery is on the moon of Sannoris. Due to the varied ecosystems found across the Kassari System, the Steel Tigers are experts at fighting and tracking in any terrain and prefer hit and run tactics to whittle down an enemy before breaking them with a charge.
Storm Angels
Storm Angels Champion.png
The Storm Angels are a 26th Founding Chapter hailing from the prestigious genome of Primarch Sanguinius, by way of their progenitors the Wings of Salvaxes. Like their predecessors, they stand aloof from the rest of the scions of Sanguinius and even from the Chapter from which they were spawned. Ritually cannibalistic and especially savages in their wars, this Chapter has recently underwent the Rubicon Primaris in full force, willing to risk annihilation to better fight against the enemies of the Imperium without sacrificing the lineage they are highly proud of.
Storm Dragons
Storm Dragons Tact Marine.png
The Storm Dragons are a Loyalist Space Marine Chapter created during the ill-fated 21st Founding, the so-called "Cursed Founding", from unknown gene-seed. Hailing from the storm-wracked world of Sturmwelt, located in the middle of the Segmentum Obscurus, their world is consumed by continuous electrical storms. This chapter is noted for it's prowess in swordmanship and melee combat. They have fought valiantly against Chaos and xenos alike as they seek the truth behind their origins even to this day. The Chapter is currently led by Tempest Lord Raihan, who leads the chapter in memory of his fallen twin Raikor. Always striving to do right by his dead brother, his Chapter, and the Imperium as a whole, Raihan is considered by his battle-brothers to be the most noble of the chapter.
Storm Fists
Storm Fists Firstborn.png
The Storm Fists are a loyalist successor chapter of the Imperial Fists created during the 15th Founding in late M35. Like their progenitors, the Storm Fists are extremely disciplined and unyielding, both when attacking or defending, often resulting in casualties beyond what the Codex Astartes would consider acceptable losses. The chapter was devastated fighting in the Dark Imperium is currently reconstituting losses from Primaris Marines that share the blood of Rogal Dorn.
Storm Griffons
Storm Griffon in mkvii.png
The Storm Griffons are a Loyalist Chapter of the Adeptus Astartes and supposed successor of the ever-venerable Dark Angels. There is no record of which Founding created these sons of the Lion, but the consensus amongst the Inquisition is that the Chapter was founded in mid M35, at the height of the Nova Terra Interregnum. Thrown into the fires of combat from the very beginning of their sigil to the throne, the Storm Griffons have faced against a myriad of mankind's foes. From the dark and claustrophobic walkways of floating space hulks to the wide-open expanses of tundra and death world plains, the chapter has been hardened and tempered in the fires of conflict. The chapter is fleet-based after the events that led to the annihilation of their homeworld Nyota IV in late M41.
Storm Heralds
Storm Heralds Tact Marine.png
The Storm Heralds are a rare Codex-compliant Successor Chapter created from the lineage of the wild and fierce White Scars during the latter half of M40 during the 25th 'Bastion' Founding . This Chapter hails from a planet with two suns, the storms heralds a time of great violence as lightning and thunder crash above, while torrential downpours of rain create flash floods. But this violence is followed by a time of peace, as the light of the suns is obscured by dark storm clouds, allowing the inhabitants a time of respite from the hot glaring suns. The chapter takes its namesake from this phenomena.
Storm Knights
Stom Knight Mk VII.png
The Storm Knights are a Loyalist Space Marine Chapter created during the 19th Founding in mid-M36 from unknown genetic lineage, however, Imperial savants believe they were created from the lineage of the mysterious and enigmatic Dark Angels. The Chapter continuously served the Emperor's will for nearly a millennium until they faced near extinction on the world of Sengor II to an unknown race of xenos. In the current millennium the Storm Knights have faced heavy combat in the Carrobract System, crusading against a never ending horde of cultists, Traitor Astartes and daemons.
Storm Marchers
Storm Marcher Intercessor.png
The Storm Marchers are a Codex-compliant Loyalist Space Marine Chapter comprised entirely of newly revealed Primaris Space Marines, created during the recent Ultima Founding of 999.M41. Their lineage descends from the gene-seed of the stoic Imperial Fists.

Although the chapter is Codex-compliant, there are a few minor alterations that the Storm Marchers have done to their equipment to better suit their style of warfare.
Storm Riders
BoK Mk VII Aquila Armour.png
The Storm Riders are a Loyalist Fourth Founding and rare Successor Chapter of the highly venerated White Scars. Created during the latter years of M32, almost nothing is known about this Chapter in official Imperial records other than that they share their forefather's battle-lust and aggressive style of lighting warfare. The Storm Riders are notable for their duality of character - being a highly aggressive and bellicose Chapter which are uncompromisingly brutal to their foes almost to the point of savagery - but are also known for their nobility of character. This Chapter is stoic and fiercely loyal in their duties of protecting the weak and the innocent, embodying all that is best in the sons of the Great Khan.
Storm Sentinels
Storm Sentinels Tact Marine.png
The Storm Sentinels are a proud and noble Loyalist Successor Chapter created from the stoic and venerable gene-seed of the great Rogal Dorn during the 25th Founding.

Making their demesne within the borders of the Segmentum Tempestus, the Storm Sentinels often combat the Ork menace that often assails this volatile region, and often conduct xenocidal campaigns to halt the greenskin menace.
Storm Sons
Storm Sons Astartes.png
The Storm Sons are a rare Successor Chapter of the venerable, highly mobile and feared White Scars Chapter. Created sometime during the 24th Founding in M39, the Storm Sons, like their forebears, enact swift and brutal justice against those who transgress against the Emperor and his Imperium of Man. Born in the turmoil of apostasy, for over two thousand years the mystic warriors of the Storm Sons have exacted swift and relentless vengeance against the enemies of the Emperor over the entire breadth of the known galaxy.
Storm Wraiths
Storm Spectres Astartes.png
The Storm Wraiths are a Chapter, that until just recently, was of both an Unknown Founding and an unknown lineage amongst the Loyalist Chapters. With a history now nearly as old as the Imperium itself, they can now verifiably trace their heritage all the way back to the ancient 2nd Founding that occurred at the end of the Great Scouring in 021.M31. Hailing from the Amerikon Sector of the Segmentum Tempestus, the Storm Wraiths have been known by many as an influential buffer for the many systems of the inner Imperium against the various foes of Mankind that constantly invade from the Galactic South. Known for their strong forward assaults from both land and sky, protected by ancient and rare wargear and support by vehicles of ancient provenance, their famed-usage of Heresy-era armour and armaments has led to a legacy of being a "ghost chapter" - a remnant of a bygone era.
Storm Zealots
Storm Zealots Primaris Intercessor.png
The Storm Zealots are Space Marine Chapter created during the 23rd ('Sentinel') Founding. They were created under commendation of the High Lords of Terra as a Successor Chapter of the highly vaunted Imperial Fists as an additional defence to the Eastern Fringe against the emerging Tau Empire, the Forces of Chaos and the encroaching Hive Fleets as well as to preserve the lives of Imperial citizens on the rich desert world of Jeras. All members of this Chapter are solely recruited from Jeras, a civilized world known for its religious citizens who are devoted to the love of their planet and the Emperor. Unlike most Space Marines that follow the Imperial Cult, the Storm Zealots and their people, the Jerasians as a whole, are also defined by their adherence to a variation of the Imperial Cult called the Jerasian Ark whose teachings espouse the veneration of the Emperor as both God and Lawgiver to them. After the famous Zerubavel Reform, the chapter is known for its innovation, possessing their own Jeras Pattern Aggressor, and Las Incinerator wielding Hellblaster Squad as well as the Shieldkiller technology.
Stormbreakers
Stormbreakers Astartes.png
The Stormbreakers are a recently created Space Marine Chapter from an unknown founding comprised mostly of the next stage of evolution of transhuman warriors - the Primaris Space Marines. It is believed that the Stormbreakers were around for longer than it is thought, since before the Ultima Founding, which would explain their inclusion of 'regular' space marines. Officially, their genetic lineage is descended from the stoic and taciturn heritage of Rogal Dorn, Primarch of the venerable Imperial Fists. However, rumours abound that the stalwart physicality displayed by these hardy battle-brothers serving in the harshest of environments and 'Zone Mortalis' warzones, is nearly on par with the XIV Legion of old - the dreaded and maligned Death Guard Legion. Although some of the Chapter's detractors believe that the Stormbreakers' gene-seed was somehow tampered with or adulterated with a different genetic stock, these rumours remain, thus far, unsubstantiated and unfounded.
Sworn of Guilliman
SoG Tact Marine.png
The Sworn of Guilliman are a formerly Loyalist Space Marine Chapter and sole known Successor Chapter of the Metamarines, created during the 26th Founding. Following the near-annihilation of the Chapter, during the events the now-rebellious Astartes call 'The Betrayal', the renamed Chaos warband, known as The Betrayed, are slowly drifting towards pure Chaotic corruption - even if its members are still far from true believers - instead favouring the use of minor daemons as auxiliaries in their raids. (Excommunicate Traitoris)
Swords of Guilliman
Swords Guilliman Tact Marine Mk IV.png
The Swords of Guilliman are an ancient Second Founding Successor Chapter of the vaunted and much lauded Ultramarines. They were initially created from the surviving members of the XIII Legioon's 19th Company that fought in the devastating Underworld War beneath the surface of Calth during the Horus Heresy, led by their famour Praetor Steloc Aethon. It was from these heroic elements that Aethon would go on to form the Swords of Guilliman Chapter, following the dissolution of the Legiones Astartes. Since those dark days of despair and shattered hopes, the Swords of Guilliman have stood against the void, never withdrawing or retreating from a threat, no matter the size or the cost to their own. Striking from their homeworld of Nova Macragge from their powerful Chapter fleet, the Swords have continued to protect the northewestern region of the Imperium, taking any mission given, as long as there is glory, vengeance or innoncent lives at stake.

Tempest Wolves
Tempest Wolves Primaris.png
The Tempest Wolves are a recently-created Primaris Space Marine Successor Chapter made from the lineage of the feral and unforgiving Space Wolves. This Chapter was formed due to the need for more guns on the front for the Indomitus Crusade and the spread of the massive warp rift, known as the Great Rift, across the length of the galaxy. Created with a new generation of the Space Wolves' geen-seed to try and lessen the effects of the 'Curse of Wulfen', they were sent to the world of Tyrheim, a relatively new planet discovered by the Imperium. They immediately assumed command of the planet and began to turn it into a bastion against the enemies of the Imperium and deployed hundreds of their warriors to fight on the front, especially Armageddon.
Templars Moline
Templars Moline Tact Marine.png
The Templars Moline are a now-extinct Loyalist Successor Chapter created from the zealous and dedicated Black Templars, whom themselves hail from the proud lineage of the stoic Primarch Rogal Dorn. Presumably created during the 14th Founding, sometime between 975-991.M35 as a part of several linked Foundings, the Templars Moline carried on the proud traditions of their Crusading progenitors and took to the stars in a massive warfleet. Later on, they would become a part of the Hell Warders - a quintumvirate of five Space Marine Chapters tasked to defend the Imperium against Chaos incursions from the Hellgates - dual warp storms located in the Segmentum Solar which are uncomfortably close to Holy Terra. Tragically, the Chapter would meet a dire end when the entirety of their Chapter fleet disappeared into the warp rifts during the Castigation Crusade of 742.M41. They were officially declared lost two years later after careful search by their fellow Warders found no survivors.

Their notable campaigns are many, such as the Hundred Years Purge in the aftermath of the War of the Beast, the Phrygian Campaign, the Galmor Chase in M34, the Extermination of Serdaex in M37, and the Battle for Korengal in M42, to name a few.
Temporal Lords
Temporal Lords Astartes.png
The Temporal Lords are a mysterious Chapter with a long and dark history. Created during an Unknown Founding and of uncertain lineage, the Chapter annals of the Temporal Lords contains a secret so dangerous that it's discovery would spell doom for the Chapter. Whatever they may have done was terrible enough that much of their early history has been completely erased and remains known only to the Temporal Lords themselves, who work tirelessly to keep this knowledge to themselves alone. Despite their melancholic exterior, the Temporal Lords are some of the Emperor's most zealous warriors, desperately seeking redemption for their past sins.
Terra's Hammers

Thunder Guardians
Thunder Guardians Tact Marine.png
The Thunder Guardians are semi-Codex compliant Loyalist Successor Chapter of the stoic Imperial Fists. Created during the 8th Founding, the Thunder Guardians have garnered a reputation as ever-vigilant, sworn defenders of the Orlrava Sector located on the southern side of the galaxy. Besieged by various xenos races, including Tyranids, Orks, Genestealers, Eldar, the Forces of Chaos and much more, their hope lies in unity with other factions of the Imperium. Their system being in a besieged state for much of its history, at the moment it is facing its worst yet. Aided by the forces of the Astra Militarum, Sisters of Battle and the Crimson Fists, they may yet stand against the tide.
Thunder Lords
Thunder Lords Tact Marine.png
The Thunder Lords are a loyalist Adeptus Astartes Chapter, coming from the 12th Founding, being successors of the XIII Legion, the venerable and honoured Ultramarines. Although somewhat Codex-divergent, they still abide by many of the Codex Astartes rules and guidelines, including sticking to the 10 Company limit.

Undertakers
Undertakers Tact Marine.png
The Undertakers are a loyalist Chapter of Space Marines that arose during the 21st 'Cursed' Founding, claiming lineage from the Salamanders Primarch Vulkan. Before the formation of their chapter, the Undertaker's home world, the Cemetery World of Creole, spent nearly a millennia as an Ork "Toof Mine", shaping the populace by influencing their culture. In addition, Drukhari experimentation during this period lead to an unusual amount of psykers appearing amongst the normal population. These factors would ultimately mold the chapter’s belief about the nature of death, the human soul, and the warp. This would ultimately draw them to the ideal of safeguarding the souls of humanity to their final rest free from the corruption of the Forces of Chaos.
Umbral Spectres
Umbral Spectres Primaris Battle Brother.png
The Umbral Spectres are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines during the most recent Ultima Founding from the lineage of the stalwart and heroic Ultramarines.

The Venerus Fathers are a small understrength Adeptus Astartes Chapter that numbers around 300-400 strong with only 10 Dreadnoughts. The chapter was founded around M40, created during an Unknown Founding, but there is no exact date. The Venerus Fathers used to be strong, numbering the authorised 1,000 battle-brothers, but after many battles and unfortunate events their numbers decreased, and with it, their strength. Despite their misfortunes the Venerus Fathers continue to valiantly take the fight the myriad of foes of the Mankind, determined to decide their fate, on their own terms.
Verum Illuminate
Verrum Illuminate Tactical Marine.png
The Verum Illuminate is a Renegade Chapter that recruits as a Loyalist Chapter created during the 8th Founding. The recruit from the Cadian Sector and planets in close proximity to the Eye of Terror, including their home world of Stygian. They teach the recruits to believe in the divinity of the God-Emperor and are steadfast in their search for the truth by the light of the Emperor's truth. However, this Chapter hides a dark truth - many of their senior officiers, including their Chapter Master, secretly follow the Chaos God Tzeentch. Though they appear to outsiders as a stalwart and trustworthy Chapter, the seeds of corruption have begun to germinate and continues to slowly erode the Chapter's loyalty.
Vindicator Lords
Vindicator Lords Tact Marine.png
The Vindicator Lords are a noble yet unforgiving Chapter of the Adeptus Astartes. As a chapter that has stood tall since M35, the Founding that occurred during this time however, is unknown, and no date has been found providing that information due to data being lost over the millennia that has passed. They're are also the few chapters that denied Primaris Space Marines, but were forced into accepting them. However, they managed to keep the Primaris numbers below 100, so the Chapter possesses only a small number of Primaris.
Void Basilisks
Void Basilisk.png
The Void Basilisks are a secretive Loyalist Space Marine chapter descended from the Raven Guard, created during the 23rd 'Sentinel' Founding during the late 38th Millennium. This Chapter is mostly trusted by other chapters of the Adeptus Astartes due to their intense religious standing, however, some factions are uneasy due to the secrecy on the Void Basilisks' homeworld Caverna Reguli Primus. The Basilisks are always sure to attack before attacked and will not falter in the face of any sign of even the slightest heresy or betrayal. The extreme and unfaltering belief in the God-Emperor of Mankind leads to the Astartes of this Chapter being ruthless and empowered, if necessary, cutting down anything unessential in their path. Due to these tendencies and their secrets, they have made enemies with both the Dark Angels and Salamanders. The Void Basilisks also dislike and distrust these two First Founding chapters as in their view, they are seen as not entirely loyal to the Emperor.
Void Paladins
Void Paladins Tact Marine.png
The Void Paladins are a formerly Loyalist Ultramarines Successor Chapter created during the 4th Founding, that was declared a Renegade Chapter, as of M36. They are mostly a fleet-based crusading Chapter but have several planetary fortress outposts for recruiting and resupply.

Void Ravens
Void Ravens Bolter.png
The Void Ravens form an ancient and nefarious Crusading Chapter, whose history is plagued by bloodshed and atrocities. Born from the ashes and death of the Horus Heresy and delivered during the 3rd Founding, they have carved for themselves a reputation of bloodthirsty and sadistic Space Marines, which has led to downfall with their Progenitor, the revered Raven Guard. Operating in the depth of space, isolated from most of the Imperium during long decades, or even centuries, those Space Marines have come several times under scrutiny from the Inquisition for their malevolent behaviour and blatant disregard of human lives and sufferings. However, their dedication to the Emperor was always deemed sufficient to avoid the harshest of punishment that could have awaited them, keeping them among the forces loyal to the Imperium.
Void Reapers
Void Reaper Mk III.png
The Void Reapers are a savage and bellicose Space Marine Chapter created during an Unknown Founding and from uncertain origin. Many Imperial savants have come to the conclusion that the Reapers are, in fact, an alleged Successor Chapter of the venerable and mysterious Raven Guard due to their similar tactics and genetic idiosyncrasies displayed by the Astartes of this Chapter, however, this remains inconclusive.
Void Walkers
Void Walkers Intercessor.png
The Void Walkers are an Ultima Founding Successor Chapter of the famed Raven Guard, comprised entirely of newly revealed Primaris Space Marines.

Though through their fierce loyalty to the God-Emperor and his Imperium even when held in persecution and exile, with ripe opportunity to turn from His light; They were granted a chance to prove they undying loyalty via penance and oath of servitude.

For a time their true Primarch and origin Legion was unknown to them, known only to those at the very pinnacle of the Adeptus Terra and the Ordo Astartes of the Inquisition, as official records state them to be Sons of Lion El'Johnson, while such a claim holds many discrepancies and is not represented in the Chapter, along with them having no significant relations with the Dark Angels chapter and it's Successors.

Their true origins remained mystified for millennia, that was until the now traitor Kasbiel Cordaras, know as the 'Black Kraken' revealed it to be -REDACTED-.

War Angels
War Angels Tact Marine.png
The War Angels are an Adeptus Astartes Chapter founded in the Illuviam System, working throughout the Ultima Segmentum as a standing force in order in better defend the the Illuviam sub-sector from hostile incursions that may threaten the territory in the foreseeable future. The Chapter is relatively young in the history of the Imperium, being founded in M37 during the 23rd 'Sentinel' Founding, resulting in relying more on more common types of equipment and wargear. The War Angels' gene-sire is that of Roboute Guilliman, informing the Chapter's demeanor of honor and loyalty as well as showing affinity for the common citizenry within their realm of influence.
War Ravens
War Ravens Astartes.png
The War Ravens are a notoriously bellicose and unforgiving Successor Chapter created directly from the genestock of the Iron Ravens, a little-known Second Founding Successor Chapter of the Raven Guard. It is unknown exactly when they were created, but many Imperial scholars believe this Chapter was created during the little-known 16th Founding, which was a part of a series of linked Foundings that occurred between 975-991.M35. Since their inception, the War Ravens have writ a legacy of death and destruction in the annals of Imperial history, carving a swathe of blood and ash across the void, their legend growing with each bloody deed and unexpected strike. Their very name has become synonymous with merciless and bloody-handed retribution, meted out on behalf of the Emperor as His harbingers of vengeance.
Warmachines
Warmachine Devastator.png
The Warmachines are a partially Codex-compliant Chapter specialising in siege warfare and heavy artillery. Clad in old Mark III 'Iron' pattern marks of armour, the Warmachines are ever pragmatic and utilitarian, utilising heavy bombardment, ordnance and overwhelming firepower to crush their foes under an unrelenting hail of munitions and shells. Their chapter warcry "Grind them to Dust" is an example of the manner in which they make war, pounding their opponents over and over until nothing remains but crumbled stone and shattered steel. To the Warmachines, war is nothing more than a series of equations solved by the application of brutal logic and determination. It is not a matter of whether they will win a battle, it is a matter of when.
Warstalkers
Warstalker Astartes.jpg
The Warstalkers are a Loyalist Space Marine Chapter of the Adeptus Astartes located on the farthest edge of the Segmentum Pacificus. The Chapter is one shrouded in mystery and can supposedly trace its origins to the bygone era of the Great Crusade, however, the chapter itself considers its Founding to have occurred in the middle centuries of M32 during the 4th Founding. The chapter has made it their purpose to stay secluded from the greater Imperium out of shame; their shame being known only to those in the inner circle of the chapter.
Wardens Metallicus
Wardens Metallicus Intercessor.png

Wardens of Orask
WO Tact Marine Revised.png
The Wardens of Orask are a Codex Astartes-compliant Loyalist Space Marine Chapter of Ultramarines lineage, created during the 7th Founding sometime during the first few centuries of M34. They were one of several Adeptus Astartes Chapters created to help quell an unknown xenos threat from beyond the Imperium's borders in the Eastern Fringe, known as the Ghoul Stars, which threatened the security of that region of the galaxy. Due to their valiant efforts, they were recognised and fêted by the High Lords of Terra, and were granted the honour of garrisoning the sentinel world of Orask, a battlefront and bastion that has guarded the Imperium from the terrors beyond. A fleet-based Crusading Chapter, since their Founding, this stoic Chapter has willingly answered the call to fight against the myriad foes that have threatened the sanctity of the Imperium of Man across the width and breadth of the galaxy, and as such, have earned the respect and admiration of both the High Lords of Terra and several of their fellow Space Marine Chapters.
White Lions
White Lion Primaris Intercessor.png
The White Lions are a fully Codex-compliant loyalist Chapter, derived from the ancient Dark Angels. They are very honourable and noble, but are without mercy in battle. In combat they can fight within every range, but they're especially feared in close combat. Their duelling and sword-fighting skills are almost unmatched and they mainly use power-swords to fight their enemies. This Chapter's speciality are sieges and large-scaled battles, where their marshal prowess and tactical minds are at their best. They are a Chapter that, like their founding Progenitors, is very knight-like and resembles these ancient warriors in a lot of ways - from their ships, all the way to their ranking and armour - they are the Knights of the 41st Millennium. Brave and honourable, the White Lions never flee and see retreat as cowardly and shameful. Unique amongst the Chapters of the Unforgiven, they have little to no connection with their founding Chapter, and try to distance themselves from them. They have much better connection with other Chapters, like the Emperor's Legion, with which they share a lot of similarities.
White Kestrels
White Kestrels Primaris Intercessor.png
The White Kestrels are a recently formed Primaris Chapter, successors of the stealthy Raven Guard. Hailing from the planet of Illyria, the surface of which is made up of thousands of floating cloud-islands, every Battle-Brother is a proficient climber and acrobat. This leads them to specialise in Infiltration, delighting in an unassailable fortress or remote bunker. Hot-headed and proud, they have clashed with more experienced chapters on many occasions.
Wild Wolves
Wild Wolves Wolf-Brother.png
Hailing from the icy death world of Fjörgyn the Wild Wolves are a particularly savage and bellicose chapter of Astartes, created during the Ultima Founding, descended from the venerable and potent lineage of the feral Space Wolves. The Astartes of this Chapter believe they are deeply touched by the Wild Wolf, the Fjörgynian God of the Hunt. Like their namesake, the Wild Wolves are savage and fiercely aggressive, their blood burning hot with the potent genetic legacy of the Canis Helix within their veins. These warriors prefer to fight at close quarters and are armed with a variety of melee weapons such as chain weapons, power axes and bolt pistols. Notoriously violent and short of temper, they eagerly rush into the fray, slaying their foes in a hail of blood and gore, battering through the deadliest foes and the direst situations to emerge triumphant, time and again.
Wind Runners
Wind Runners Tact Marine.png
The Wind Runners are a Loyalist 10th Founding Chapter of the Adeptus Astartes who are descended from the lineage of the savage and proud White Scars Chapter. The Chapter is most well known for their precision execution of the various forms of combat listed in the Codex Astartes. Their most prevalent form of combat is their bike or mobile forces, which are known to zoom into the battlefield, ready for a fight. The Chapter has known hardships and loss over the span of a millennia, with many of their victories being in defense of their home planet, Hinduja Velo, and in service of the Emperor when humanity requires defending.
Winds of Fury
Winds Fury Astartes.png
The Winds of Fury are a loyalist Codex-compliant Successor Chapter created from the proud lineage of the revered Raven Guard during the 23rd Founding, the so-called 'Sentinel Founding'. This near mysterious chapter was created following the liberation of Ryunkai against the Orks of Klan FaceChoppa by the famous Shadow Captain Alerin of the Raven Guard's 3rd Company. The chapter continues to practice the art of stealth, guerrilla warfare and close-combat using the combined teachings of their ancestors while fighting the "Green Oni", aka the greenskins, and the wisdom of the Raven Guard Chapter. The chapter is known to operate independently and never depends on any other chapters aside from those that earn their respect.
Winged Knights
Winged Knights Tactical Marine.png
The Winged Knights are a Loyalist, non-Codex-compliant Space Marine Chapter drawn from the lineage of the vaunted Blood Angels during the 4th Founding. Though their lineage is clear, the exact Chapter from which they can claim to be the successors of is not. It has long been suspected that they are a Successor Chapter of the Angels Sanguine, the truth of that suspicion has yet to be confirmed. Though they were a Chapter of great honour for approximately two millennia, the stain of heresy has marred their reputation and they have never been able to escape the its legacy.
Wings of Salvaxes
WoS Astartes.png
The Wings of Salvaxes, in their brief existence as a Space Marine Chapter have carved for themselves a vicious and brutal reputation for wanton slaughter and savage violence. Alone they stand amongst the noble Sons of Sanguinius as dark pariahs of all that the Blood Angels lineage seek to avoid. Eschewing the jump pack assaults of their Primogenitors and sister chapters, the Wings of Salvaxes instead make use of massed mounted charges, spewing forth death from their guns unhindered by their savage recoil, before crashing into their foes like an avalanche - chainswords hacking and wheels crushing all that stand in their way. Their momentum expended, they will peel away from the assault as their psychotic Death Company terminators join the fray in a bloodbath of blasting stormbolters and crackling power fists. They will then either roar off to find more foes, or circle around and join their terminator brethren in the slaughter of the Emperor's foes.
Wolf's-Head Marines
Wolf's-Head Astartes.png
The Wolf's-Head Marines are a non-Codex compliant Space Marine Chapter created during an Unknown Founding and of uncertain lineage. Despite their liberal use of the wolf iconography in their heraldry, there seems to be no connection to the ancient and feral Space Wolves.
Wolves of Redemption
Primaris Moonlit Hunter.png
The Wolves of Redemption is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the lineage of the Space Wolves and raised during the Ultima Founding of 999.M41. After the disbanding of the Unnumbered Sons, the Primaris Space Marines of Leman Russ's lineage became members of either the Wolves of Redemption or other successor of Leman Russ. Like their brother-chapter, the Wolfspear, the Astartes of the Wolves of Redemption fear that the Space Wolves will not see them as 'true inheritors of the legacy of the Wolf King. Though they know that some Space Wolves have accepted Primaris Space Marines like them into the ranks of their Chapter, they that some of the Space Wolves have denied the Primaris Astartes and their right as 'true inheritors' of the legacy of the Wolf King.
Wolves of Retribution
WoR Marine.png
The Wolves of Retribution are an infamous Chaos Warband that was formerly a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage. There are many tales of loyal Chapters falling to the temptations of Chaos. Some falls are obvious, such as the infamous Crimson Sabers, while others are surprising. The fall of the Wolves of Retribution falls into the latter category. Once, they were proud heralds of the God Emperor but now they are heralds of damnation. It is perhaps the greatest misfortune that the Wolves of Retribution cannot see what they have become. They still see themselves as the loyal warriors of the Emperor, blind to the chaotic corruption that warps their armour, twists their flesh and perverts their scripture. The angels they fight alongside are daemons of the Octed. Even the fire they hold sacred has been turned by the warp, damning the souls they claim to save.
(Excommunicate Traitoris)
Wolves of Terra
Wolves Terra Astartes.png
The Wolves of Terra are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 4th Founding in the middle centuries of M32. Created from unknown lineage, the origins of their gene-seed has been classified at the highest levels. Savage, highly aggressive and relentless are words that best describe the Wolves of Terra in combat as well as their independent nature, as they are only a semi-Codex compliant Chapter. Since their inception, the Wolves of Terra have garnered a reputation as a bellicose and savage Chapter, ruthlessly slaughtering the enemies of Mankind with the chapter's prefered weapons of chain-axes and chainblades.
World Marauders
WM Mk VII Battle-Dmg.png
The World Marauders are a Loyalist Space Marine Chapter of the noble White Scars formed during 23rd Founding, also known as the 'Sentinel Founding'. A fleet-based Chapter, the World Marauders move as a singular powerful force, striking planet after planet filled with the enemies of mankind. Space fairing, they do not adhere to the authority of the Imperial higher-ups, seeing them as weak-minded and corrupt. They have garnered a reputation of attacking human pirates, recruiting from their ranks or forcing others to become their serfs.

Yearning Ruin

Pict-File Unavailable

The Yearning Ruin are a non-Codex Compliant Chapter of Space Marines taken from the gene-stock of the Raven Guard Chapter. They were created during the ill-fated 21st Founding, the so-called 'Cursed' Founding, due to the massive flaws and unforeseen genetic idiosyncrasies and mutations that affected most of the Chapters of this particular founding. The Yearning Ruin are a dour and life-dismissing Chapter whose Astartes are doomed to die in either glory or great nigh-eternal personal shame.

Zero Legion
Zero Legion Lieutenant.png
The Zero Legion is a mysterious Space Marine Chapter of Unknown Founding and of uncertain lineage. There is very little information on them, and what little exists, is sealed away in the deepest vaults by the Inquisition. This unusual chapter has shown to possess numerous technologies and weaponry of the early days of the Imperium, thought loss during the Horus Heresy, as well as relic archaeotech from the Dark Age of Technology including incredible Warp Technology too. How they came to obtain such powerful and forbidden technology is unknown. These Astartes have shown to possess high resistance to the warp, as well as strong regenerative healing factors, able to reattach severed limbs. They have also shown a deep grudge against not just the Chaos Space Marines of the Traitor Legion, but also the Ecclesiarchy, viewing the former as a threat to mankind, and the latter as a disease.
