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.
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 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. Angel's Litany is created following the liberation of Ragrin System from the Forces of Chaos led by House Moghal, and the Chaos Cult known as the Blooded Fist of Maurha. 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.
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. (Note:This Chapter falls under the Expanded Universe category.)
The Angels of Damnation are an ancient Chapter believed to hearken back to the Second Founding, whose origins has been lost to time and bureaucracy. Even the Chapter themselves can't remember the origins of their gene-seed. But the Angels of Damnation are more well known for their violent behaviour and traditions, giving them a reputation as psychopaths and careless killers. This bellicose Chapter has vowed to always, and until the end of the Imperium, to crusade against the Forces of Chaos, hunting down the heretic and burning out the corruption without care for the innocent lives in their way or the material damages. (Note:This Chapter falls under the Expanded Universe category.)
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.
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.
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 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.
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.
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.
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.
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)
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.
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.
The Astral Warriors are a 23rd 'Sentinel' Founding Successor Chapter of the infamous Astral Claws Chapter, created after the Taninim Crusades where their Progenitor retrieved an Adeptus Mechanicus Ark ship. The battle-brothers of the newly fledged Chapter swelled with pride from their noble origins, but that would not last for long. After the heresy committed by their progenitors during the infamous Badab War, the Astral Warriors strode to prove both their purity and their loyalty to the Imperium of Man, no matter the cost to themselves. Many times have the Warriors struggled against the suspicions of both the High Lords of Terra and the Inquisition for their heritage, but despite it, have served admirably and faithfully as any true soldiers of the Emperor could.
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.
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.
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)
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.
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.
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.
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.
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.
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'.
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.
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. (Ecommunicate Traitoris)
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.
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.
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.
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.
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.
The Bloodmoon Legion is a Chapter of Loyalist Space Marines created during the 21st 'Cursed' Founding, whos lineage originates from the venerable Dark Angels. The Bloodmoon Legion maintains very close ties with the radical wings of the Emperor's Holy Inquisition and shares many of the radical views their allies have. As a crusading Chapter, the Bloodmoon Legion lives to serve the Imperium of Man and the God-Emperor of Mankind by any means possible, no matter how unsavory.
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.
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.
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.
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.
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. This Chapter was created to stand sentinel over the vitally important Gudan Sector, located in the Ultima Segmentum, from the various enemies of Mankind. As a fleet-based Chapter, they constantly patrol their assigned region of the galaxy, ever-vigilant against the threats of invasion by the various xenos within the region or the vile Forces of Chaos. Their primary recruitment world is the world of Gudan Prime. The Chapter maintains a massive Chapter Keep, built atop the tallest spire of Hive Vaxilian. It is here, that the Bulls maintain their Chapter's vitally important gene-seed banks, reliquary and recruitment and training facilities.
The Burning Fate are an Ultima Founding Successor Chapter of the vaunted Blood Angels comprised entirely of newly revealed Primaris Space Marines. This chapter, like some of their fellow successors, have garnered an infamous reputation across the Segmentum Tempestus due to their extensive use of fire weaponry and brutality on the battlefield.
The Carbon Fists are Loyalist Successor Chapter created from ancient and proud lineage of the vaunted Ultramarines. They were created 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. This Chapter came to epitomise themselves as a force that specialises in medium-ranged combat and a hunter-killer force. They also became well known for their sense of honour and their propensity for conducting the martial tradition of honour duels, which were inherited from the ancient feudal customs of their Chapter homeworld of Goldavos Prime.
The Castigators are a rare Successor Chapter of the Black Consuls Chapter. Created during the 14th Founding sometime between 975-991.M31, the Castigators have earned a reputation as staunch and stalwart guardians of the Imperium in the millennia since their inception. The Castigators are a zealous and unforgiving Chapter who have garnered a reputation for their fervent desire to purge the enemies of the Emperor for their transgressions.
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.
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.
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. Created during the 23rd 'Sentinel' Founding, this Chapter hails from the harsh desert world of Atum. 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.
The Corpse Kings are a notorious Renegade Space Marine Chapter that were originally known as the Star Hunters, a Successor Chapter of the Ultramarines that was created during the mysterious 13th 'Dark' Founding. Due to the destruction they brought upon both friend and foe alike in their obsessive search to recover forbidden artefacts of Chaotic origin, the newly renamed Corpse Kings were eventually declared Renegade and were excommunicated by the High Lords of Terra on the advice of the Inquisition. Despite their outcast status, the Corpse Kings still consider themselves loyal to the God-Emperor, if not to His Imperium. (Excommunicate Traitoris)
The Corpse Wolves are an Ultima Founding Successor Chapter created from the proud lineage of the feral Space Wolves. The Corpse Wolves were one of several new Successor Chapters comprised entirely of Primaris Marines, created to help defend the Imperium of Man from the various enemies of Mankind, that currently assailed the Emperor's realm on all sides. 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 Astromican, and the light Imperium.
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.
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.
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.
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.
The Crimson Sentinels are an ancient and laudible Successor Chapter created during the 2nd Founding shortly after the events of the Horus Heresy from the lineage of the noble Blood Angels. 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.
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'.
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.
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.
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 a excommunicate Rogue Trader.
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.
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.
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. (Excommunicate Traitoris)
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.
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.
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.
The Emperor's Liberators, known formally as the 'Imperatoris Liberatae', are a 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. This would shape the chapter's fate for years to come.
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.
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 trace their lineage back to the Second Founding, though 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.
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. Citizens of Parvat Obscurum refer to themselves as the Gurukhali, which roughly translates to "Main Tribe" in the native tongue.
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.
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.
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.
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.
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.
The Feral Sons is a Codex-Divergent Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the venerable lineage of the Imperial Fists and raised during the recent Ultima Founding of 999.M41. The Feral Sons' self-appointed task is to patrol the Cicatrix Maledictum, as many foul abominations emerge out of that great rent in reality. In addition to slaying the Emperor's enemies, the Feral Sons diligently seek a method of reconnecting with the hundreds of thousands of worlds cut off in the galactic north of the Imperium Nihilus.
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.
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.
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.
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.
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.
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.
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. (Exommunicate Traitoris)
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.
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.
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.
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.
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.
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.
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.
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.
The Imperial Sentinels are a 6th Founding Successor Chapter of Imperial Fists' lineage that have been waging war across the stars in the name of the God-Emperor for seven thousand years. A serious, dour and subdued lot off the battlefield and an inexorable, unstoppable line of black and gold on it the Sentinels have earned the respect, even reluctantly and begrudgingly, of many they have fought beside. They are highly disciplined, fearless, and know not the meaning of the words hubris or arrogance. The warriors of the chapter do not break formation to pursue an apparently routing foe unless ordered to. Some chapters of Astartes deem them cowardly and/or dishonorable for not seeking personal glory, but an Imperial Sentinel desires not fame nor reward, only victory at any cost.
Known also as the 'Headsmen of Charopós', the Imperius Ravagers are a bloody-handed and bellicose Chapter created from the honourable Ultramarines. Created in the wake of the War of the Beast, the Imperius Ravagers 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.
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.
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.
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)
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'.
The Iron Dragons are one of the Loyalist Space Marine Chapters created during the 5th Founding , which occurred sometime in the second century in M33. 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. They are also well known for their similar humane treatment and concern for the lives of innocent citizens of the Imperium as their supposed Progenitors. Almost nothing else is known about this Chapter in official Imperial records other than that they have continuously stood firm in their beliefs, as paragons of strength, honour and resolution in accordance to the legacy of their Primarch.
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.
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").
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.
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.
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.
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.
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. (Note:This Chapter falls under the Expanded Universe category.)
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. (Note:This Chapter falls under the Alternate Universe category.)
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.
The Knights of Sol are a Loyalist Space Marine Chapter from the 19th Founding, descended from the PrimarchRogal 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.
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.
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.
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.
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.
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.
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. In the five millennia since their founding, the Guard have become characterized for their concern of civilian casualties by putting their duty as protectors of the Imperium’s people as their primary objective during their operations.
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.
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.
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.
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.
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.
The Mourning Wardens are a 26th Founding Successor Chapter of the stoic and venerable Imperial Fists. 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The Ordo Angelus, which translates to the 'Order of the Angel' in High Gothic, is a Successor Chapter of the proud and noble lineage of the angelic Primarch Sanguinius. Created during the 3rd Founding in 001.M32. Despite the unsavoury reputation of their fellow cousin-Chapters created during this Founding, the Ordo Angelus somehow maintained the nobler aspects of their Progenitors, winning the approbation of other Chapter Masters, Planetary Governors and even the High Lords of Terra themselves. But like many of their fellow Scions of Sanguinius, it was darkly whispered amongst some of the Chapter's detractors that the Ordo Angelus' sense of cause and purpose manifested as unflinching, unreasoning fanaticism bordering on madness.
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.
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.
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. (Excommunicate Traitoris)
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.
The Polar Flares are a 4th Founding and rare Successor Chapter created from the lineage of the shadowy Raven Guard. This Chapter was formerly located in the Polaris Sector, but have turned renegade and accompanied the 'Crusade of Renegades' trek to the Solarain Sector, which they meet with the abhumans known as the Elementi. (Excommunicate Traitoris)
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.
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.
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 (Excommunicate Traitoris)
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.
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. (Excommunicate Traitoris)
The Sanguinary Blades 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.
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.
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.
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.
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.
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.
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.
The Silver Dominators are a Semi-Codex Compliant Astartes Chapter of Marines Malevolent descent. Originating from the 13th "Dark" Founding, the Silver Dominators are deeply loyal to the God Emperor of Mankind and the eradication of His enemies. However, much like their parent Chapter, the Silver Dominators have at times shown a disturbing and callous disregard for the lives of the civilians of the Imperium as long as their mission objectives are achieved. This has brought them into conflict with many Imperial organizations, including the God Emperor's Holy Inquisition.
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.
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.
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.
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.
The Sons of Galastram are a 25th Founding Successor Chapter of the honored Penitent Knights Chapter. Created during M40, the Sons of Galastram proudly adhere to the near chivalric culture of their forebear Chapter, adopting many of the customs, strategies, and beliefs. Like the Knights, the Sons fervently believe in the value of civilian life and will gladly endure many hardships to secure their safety. Because of this, or perhaps the reason for it, being that the Chapters have maintained a very close relationship, the Sons seeing the Knights as their noble fathers. However, differing from their parent Chapter, the Sons of Galastram are mostly a crusading Chapter, roaming the Imperium for foes to slay, though sometimes taking periods of time to defend their parent Chapter's system to rebuild their ranks.
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.
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.
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.
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.
The Spartiate Marines are an Ultramarines Successor Chapter created during the 4th Founding sometime during the late fifth century or early sixth century of M32. They act as a designated offensive force, and paired with those defensive experts the Gatekeepers, are a part of the Hell Warders Chapters - a quintumvirate of five Space Marine Chapters - tasked to defend the Imperium against Chaos incursions from the dual warp rifts known as the 'Hellgates' of Sector Occident Prime, located in the Segmentum Solar uncomfortably close to Holy Terra.
The Spearheads are a formerly Loyalist Space Marine Chapter created during the lamentable 21st 'Cursed' Founding from the vaunted lineage of the Ultramarines. They were created by a group of Tech-Priests to created an Ultramarines Successor Chapter with a lower mutation rate than even their genetic forebears. Initially deemed successful, the Spearheads were considered one of the few successful Cursed Founding results and inherited the planet of Kastarsuz IV as their homeworld. However, this purity came at a cost. Although the Chapter was freed of physical mutations, their minds had become significantly weaker than the minds of other Astartes. The Astartes of the Chapter were more likely to develop mental disorders and were still corruptable by Chaos even when they were under the protection of their Brother Librarians. Eventually, they fell from grace, becoming the notorious Chaos Warband known as the Ashen Exiles. (Excommunicate Traitoris)
The Spectral Wolves are non-Codex adherent Chapter that was created from unknown lineage. 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. Due to their unknown Founding and origins, the Spectral Wolves are sometimes viewed suspiciously by most other Space Marine Chapters, despite the Inquisition finding them free of Chaotic-taint or mutation. This Chapter is known for possessing an inordinate amount of power weapons compared to most other Adeptus Astartes Chapters.
The Star Hunters are a Renegade Space Marine Chapter of Unknown Founding and uncertain origins. They are infamous for their acts of piracy, which involve attacking spacecrafts of various races, as well as worlds, and salvaging abandoned facilities, bases, Space Hulks and even battlefields. They also attack the bases of various races, primarily humans, Orks, Eldar and Tau. Despite that, the chapter has also been known to sometimes engage battle with Chaos Forces, attacking them until there is nothing left.
The Star Knights are a 4th Founding Chapter, descended from the Ultramarines. Well known for the skills of adapting to any combat situation, 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 adapt and change their tactics on a whim when facing the foes of man.
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.
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.
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.
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. As proud inheritors of Dorn, like their genetic forebears, the Storm Sentinels are also specialists in siege warfare as well as ranged combat. 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.
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.
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.
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 both the Forces of Chaos from the Warp anomaly known as the Maelstorm, the emergent Tau Empire, the tendrils of encroaching Hive Fleets and 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.
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)
The Tempest Knights are a Codex Astartes-compliant Loyalist Chapter of Space Marines who are a 4th Founding Successor Chapter of the Imperial Fists.The newly created Chapters of this Founding were created to help restore order to to an Imperium rife with civil upheaval and insurrection. Since their inception, the Tempest Knights have continued to maintain order and bring swift justice to those who would dare sow discord or preach rebellion.
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.
The Templarii Scientae, or Templars of Knowledge in Low Gothic, are a strange and esoteric Loyalist Space MarineChapter. Their exact origins and circumstances surrounding their creation is shrouded in mystery, as are their constant whereabouts. The chapter is known to be in possession of an incredible amount of exotic and finely made wargear, likely scavenged from ancient battlefield and restored to war-capable status. What few extant accounts that exist, the only thing that can be ascertained for certain is that this ancient Chapter officially appeared sometime during the 32nd Millennium. Officially, they are listed as hailing from the genetic lineage of the venerable First FoundingDark Angels. But the truth of their heritage is a far more complicated and complex issue - one that could see them fall under the scrutiny of outside Imperial authorities and see them yet declared as renegades.
The Templars of Iron are a Successor Chapter of the Iron Hands. These scions of Ferrus Manus are noted for their stern demeanour and ruthless persecution of their foes. This Chapter, along with the Iron Gorgons and the Iron Harbingers, make up a triumvirate of 2nd Founding Iron Hands' Successors, collectively known as the Frateris Firmitatis ("The Ironclad Brotherhood"). Since their inception, the Templars of Iron have amassed a substantial tally of glorious victories down the millennia. Like their Progenitors, they too, have a hatred of the flesh and share their predilection for replacing parts of their bodies with bionics and cybernetic enhancements. In battle, the Templars are noted for their stoic resolve and stubborn determination to succeed in the face of overwhelming odds, as they fight on without remorse for their foes, or even their own lives.
Terra's Cockroaches are an ancient Loyalist Space Marine Chapter known throughout the Imperium as being from proud lineage of the heroic Ultramarines.

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.
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. The Thunder Lords, though once a very isolationist Chapter and only staying in their system and defending it, have recently began to spread themselves out and help the sub-sector, and even to the Segmentum that they reside in, the Segmentum Pacificus.
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.
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.
The Void Wyverns are loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created during the recent Ultima Founding in 999.M41, from the lineage of the great Salamanders.

All members of this Chapter are solely recruited from Drukar Prime, a feral world filled with swamps, toxic bogs, and crannog tribes that constantly war among each other. The Chapter is known for its close assault tactics, armoured assault, and close-range combat, possessing a large quantity of assault flamers and melta incinerator wielding Inceptor Squads that is unique amongst many other Primaris Space Marine Chapters.

They rarely, if ever, leave witnesses behind.
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.
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.
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.

In order to accomplish this, the chapter has specialised in strong defensive warfare with the help of it's unusually large force of dreadnoughts.
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.
The Wild Hunt is an Ultima Founding Space Marine Chapter comprised entirely of Primaris Space Marines created from the gene-stock of the feral Space Wolves. This Chapter is based in the Segmentum Tempestus on the first moon of planet Skadi known as Utgard. Known for their tactics resembling a pack of wolves hunting, with deep-strike and infiltration units bleeding their prey dry while the bulk of their forces circles and moves in for the kill, the Wild Hunt carries forth a peculiar variation of Fenrisian folklore, where the cult of Morkai has a prominent place.
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.
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.
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.
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.
