Fleet-Based Chapters

This article, Fleet-Based Chapters, is a community project. While you are free to edit, please do not edit or delete anything written by another user without their permission. This page was last edited on 3/4/2024 by Algrim Whitefang.

This article is comprised of a complete list of all the fanon Fleet-Based Chapters listed here on the WH40K Homebrew Wiki. Fleet-Based refers to Space Marine Chapters not based on a Chapter homeworld. They possess only a fleet with one of the fleet ships usually serving as their Chapter's mobile Fortress-Monastery. They are naturally among the most mobile Chapters. Some fleet-based Chapters are also called Crusade Chapters. Many Chapters who rebelled at some point but were later granted the Emperor's forgiveness are often fleet-based, crusading Chapters because they were forced to forfeit their homeworld. Included in this list are Expanded Universe Chapters as well as those fleet-based Space Marine Chapters that have been declared Excommunicate Traitoris by the High Lords of Terra, regardless if they serve the Dark Gods or not. This list does not include Space Marine Chapters that fall into the humour category. This is an ongoing project, and as such, additional Chapters will be added or removed accordingly. For those Chapters that are missing from the list, please feel free to edit this article and add it, or if the Chapter article has been deleted, feel free to remove it.

List of Fleet-Based Chapters[]

A[]

Name	Symbol	Allegiance	Flagship	Notes
Aardwolves		Imperium of Man (Fidelitas Totalis)	Howl of Darkness	The Aardwolves are a fleet-based, loyalist non-Codex compliant Space Marine Successor Chapter created from an unstated lineage and comprised entirely of newly revealed Primaris Space Marines. The Chapter keeps to themselves, preferring to wage their own war against the enemies of Mankind. They choose to never fight alongside other forces of the Imperium or join a battle on the orders of others than themselves.
Abyss Gazers		Imperium of Man (Fidelitas Totalis)	Unchanging Fortress (Space Station)	The Abyss Gazers are one of the Chapters created during the ill-fated 21^st Founding, the so-called 'Cursed Founding'. The Abyss Gazers were founded to police the edges of the Eye of Terror and have only just managed to survive due to both bad luck, mutation, and a section of the chapter breaking away and turning to Chaos. After nearly twice being declared Excommunicate Tratoris, the chapter is now somewhat closely monitored by the Inquisition, much to their ire.
Angels Mortis		Imperium of Man (Fidelitas Pietas)	Angelus' Fury	The Angels Mortis are a devoutly religious 23^rd 'Sentinel' Founding chapter who claim the lineage of the First Legion and the bloodline of the holy Primaris Angelus Mortis. The chapter has its own unique view of the Imperial Creed leading them to view the Lion as the first Imperial saint and the Emperor's Angel of Death who will guide them to the Emperor's side. For most of their history the chapter focused on the gathering of holy artefacts linked to the Primaris Angelus Mortis and bringing the word of the God-Emperor to all across the galaxy, whilst mercilessly purging those who refused it. However, their legacy of dedicated and stalwart service has been tarnished by accusing their fellow Unforgiven chapters, the Silver Lions and Ebon Angels, of heresy and collaborating with the Fallen leading to the War of the False Traitor. The Angels Mortis would be defeated in this war and for their ignorance were excommunicated from the Unforgiven and left as a broken chapter. The Angels now seek to repent for their past sins and seek to regain their former grace amongst their fellow Unforgiven.
Angels of Anguish		Imperium of Man (Fidelitas Totalis)	Eternal Prince	The Angels of Anguish is a semi-Codex Astartes-compliant Loyalist fleet-based Successor Chapter created from the gene-seed of the ancient and heroic Blood Angels Chapter during the 2^nd Founding. Created as they were from the Blood Angels' gene-seed, the Angels of Anguish also carry the genetic Flaw inherited from their Father Sanguinius. The Angels of Anguish, a most peculiar Chapter of the Blood, stand apart from their fellow Successors due to their unique devotion and practice of martial arts. They are renowned for their exceptional skill in unarmed combat, and the Chapter has a strong culture of competition when it comes to dueling and hand-to-hand fighting.
Angels of Twilight		Imperium of Man (Fidelitas Tenebrae)	Second Penance	The Angels of Twilight is a loyalist Space Marine Chapter created during the 4^th Founding from the lineage of the ancient and aloof Dark Angels. This Chapter is known for rapidly deploying Fire Support Squads deep into enemy lines with Drop Pod assaults; delivering the maximum amount of damage to key enemy personnel and structures as quickly as possible. Like most Chapters of the Unforgiven, the Angels of Twilight are a fleet-based chapter ever on the hunt and tend to steer clear of others - focusing on their own shadowed agendas.
Angels Vampiric	Pict-File Unavailable	Imperium of Man (Fedelitis Scindere)	Fang of the Cherubim	The Angels Vampiric are a non-Codex compliant, fleet-based Successor Chapter of the heroic Blood Angels Space Marine Chapter. Founded around M34 as the result of a failed secretive experiment. The experiment in question was meant to cure the Blood Angels of the dreaded 'Twin-Flaws' known as the Red Thirst and the Black Rage, however, it went horribly wrong and instead amplified these genetic flaws. After the experiment was declared a failure, it was decided that instead of purging the subjects of the experiment, a new chapter would be created from the surviving test-subjects. The highest ranking of these test-subjects, a sergeant by the name Count Orlok took up the position of chapter master of the new chapter. The Angels Vampiric are loyal to the God-Emperor of Mankind, however, they have been known to worship their Primarch Sanguinius more so than they worship the Emperor. They hold the belief that eventually, Sanguinius will return and restore the Emperor to his original power, and together the two of them will lead the Imperium to greatness once again.
Arachnid Warriors		Imperium of Man (Fedelitas Totalis)	Venom	The Arachnid Warriors are a Codex-compliant Chapter formed during the 23^rd 'Sentinel' Founding during the 37^th Millennium. Formerly declared Renegade (Excommunicate Traitoris) from 345.M41 to 013.M42, the Chapter has since been brought back into the Imperial fold after an investigation by Inquisitorial forces determined the original charges of Heresy against the Chapter proved to be unfounded, as well as the Chapter proving it's loyalty and lack of corruption in the Hyperion War that lasted from 999.M41 to 013.M42.
Archangels of Manasseh		Imperium of Man (Fidelitas ad Mortem)	Jirah	The Archangels of Manasseh is an ancient and highly respected Loyalist Successor Chapter that hails from the lineage of the heroic and stalwart Ultramarines. Created in the wake of the tragic events of the Horus Heresy and the subsequent dissolution of the Legiones Astartes, the Archangels were created during the 2^nd Founding. The Archangels of Manasseh were one of several 'Primogenitor Chapters' created during this time. The Ultramarines maintained the XIII^th Legion's original name, badge and colours, while the remaining created Chapters took new names and heraldry. Shorn of their past history and livery, the Archangels were free to forge their own path. However, due to the destruction of their planet, they have become a fleet-based chapter.
Armageddon Sons		Imperium of Man (Fidelitas Scindere)	Avenging Will	The Armageddon Sons are an ancient Loyalist Space Marine Chapter created from the vaunted heritage of the honourable Ultramarines. Officially, this Chapter was listed as being created during the 3^rd Founding, however, scant evidence indicates that this Chapter might have been created much earlier as there are scattered reports of them first appearing in the early years of M32. The truth of the matter is much darker, and is no known outside the Chapter. The origins of the Armageddon Sons actually harkens back much earlier, to a bygone age when the Imperium first took the stars and conquered the known galaxy. Unknown to anyone, save the Emperor Himself, is that the Armageddon Sons were in fact descended from a small loyalist element from the Sons of Horus that managed to hide their allegiance and escape before the events of the Isstvan III Atrocity.
Ashborne Drakes		Imperium of Man (Fidelitas Totalis)	The Foundry	The Ashborne Drakes are a Loyalist Successor Chapter of the Adeptus Astartes created from the lineage of the heroic Salamanders Chapter. They were created during the 19^th Founding in M36, to help defend the realm of the Emperor of Mankind from the threat of both heretics and xenos.
Ashen Apostles		Imperium of Man (Fedelitas Totalis)	Iron Library	The Ashen Apostles are a Loyalist non-Codex compliant Space Marine chapter descended from an unknown parent Chapter founding during the 21^st 'Cursed' Founding. The chapter earns the distrust of other chapters simply being born during the time of the Cursed founding, however, is not the only thing that earns them the distrust of other Astartes. The Apostles' preference for diplomacy rather than all-out war which has made war-loving chapters such as the Space Wolves and Black Templars dislike the Apostles even more. When in and out of battle the Apostles are some of the most fanatical worshipers to the God-Emperor of all Astartes, because of this many of the worlds the Chapter has conquered are now highly religious due to the Apostles' influences.
Ashen Heralds		Imperium of Man (Fedelitas Totalis)	Vengeance Reborn	The Ashen Heralds are an ancient Chapter of Space Marines of unclear origin and descent. Through the chapter’s long history of service, it has earned a reputation for fielding pragmatic, stoic marines, intent on waging war on the foes of the Imperium with a cold fury. The earliest history of the Ashen Heralds is largely unknown, much information on them was lost in the wake of catastrophic losses against the forces of Chaos that left the chapter on the verge of extinction. Through the grace of the Salamanders chapter, which loaned veterans and officers to guide the few surviving Heralds in raising the next generation of neophytes, the chapter survived, and has gone on to wage war in the name of the Emperor for millennia.
Ashen Thanes		Imeprium of Man (Fedelitas Sine Recursu)	Star Keeper	The Ashen Thanes are one of the oldest, non-founding chapters in the Imperium. Created sometime during the 4^th or 5^th Founding, and from uncertain lineage, they were formerly known as the Iron-Bound Thanes, and are the parent chapter of the Exalted Paladins. Unfortunately most of the early records of the Iron-Bound Thanes were lost in the destruction of the Chapter's original fortress-monastery, Tol Elmoth, in M37 when the Blood God-worshipping World Eaters Traitor Legion attacked their homeworld, Taur-Hithlum. Rebuilding in the aftermath of this devastating attack, the Chapter reforged their sorely depleted ranks and renamed themselves the Ashen Thanes. Since that tragic era, the Ashen Thanes have gone on to become a well-respected Chapter. Following the fall of Cadia and the formation of the Great Rift, the Ashen Thanes' entire home system has seemingly vanished. The current whereabouts of the Chapter is unknown.
Astra Romana		Imperium of Man (Fidelitas Totalis)	Imperium Invictus	The Astra Romana or in Low Gothic, the 'Sentinels of Ultramar', is a Loyalist Successor Chapter created from the lineage of the venerable Ultramarines. They were created during the 23^rd Founding, otherwise known as the 'Sentinel Founding', in order to strengthen the Imperium's defenses during the late 37^th Millennium. Early in the Chapter's history, they found fragments of records that were written by the Ancient Terran Romanii on one of their voyages. In order to pay homage to this civilization that was unfortunately extinct, they decided to adopt their culture into their own Chapter.
Astral Canids		Imperium of Man (Fedelitas Totalis)	The Kennel	Many have been the possible origins proposed for the Astral Canids, though none can have been ascertained. Though the Astral Canids are officially registered as part of the Fourth Founding, right after the conflict knowns as 'the War of the Beast' and in the context of the coup known as 'the Beheading', these records are contradictory with the battle records of that conflict, for they shown that a Chapter with the same name and livery answered to Lord Commander Koorland's summoning to enact the 'Last Wall' protocol. The Astral Canids answered to that call as all the descendants of Dorn did. However, they denied belonging to that gene-lineage. (Note: This Chapter falls under the Expanded Universe category.)
Astral Carbines		Imperium of Man (Fedelitas Totalis)	Unwavering Bolt	The Astral Carbines are an Ultramarines Successor chapter founded during 27^th 'Ultima' Founding, composed primarily of Primaris Space Marines. The Astral Carbines were hailed for numerous victories, overcoming hardships which would've broken most people. However, their strength and virtue did not last forever; the Astral Carbines were fractured, as the Warband Arcane Reavers was borne from the Astral Carbines' traumatizing experience in the Warp. The loyalist Astral Carbines gave their all to defeat their fallen brothers, with the final battle being on the planet of Casimus. The Astral Carbines slowly but surely rebuilt after a 25 year Penitent Crusade, with Casimus officially became the home-world of the Astral Carbines.
Astral Reapers		Imperium of Man (Fedelitas Tenebrae)	Pit of Death	When the xenos, daemons, and heretics feel themselves victorious against mankind, then come the black hooded enforcers of the Emperor's will, as silent as the dead of night, to break both the enemy's morale and bodies, and they shall gloat nevermore. They are the Astral Reapers, sons of the Primarch Corvus Corax, born during the 3^rd Founding. Having no home world to call their own and being a crusading chapter, these descendants of the Raven Guard wage stealth and guerrilla warfare against the enemies of mankind as the shadow-draped dagger of the Emperor's justice.
Atomic Gladiators		Imperium of Man (Fedelitas Totalis)	Atomic Fury	The Atomic Gladiators are a 2^nd Founding Iron Hands fleet-based Space Marine Chapter that are rumoured to posses Astartes far above the Codex Astartes-proscribed 1,000 battle-brothers.
Avengers of Tyran		Imperium of Man (Fedelitas Totalis)	Behemoth's Bane	The Avengers of Tyran are a semi-Codex compliant Ultramarines Successor Chapter comprised entirely of Primaris Space Marines - created during the recent Ultima Founding from the remnants of the survivors of the Tyranid-ravaged planet of Tyran. A highly mobile force, this newly created Chapter combatx the many Splinter Fleets of Hive Fleet Behemoth.

Baleful Boars		Imperium of Man (Fedelitas Atrox Extremis)	The Butcher	The Baleful Boars is a very small and endangered Loyalist non-Codex compliant Space Marine Successor Chapter created from the lineage of the Blood Angels Space Marine Chapter during a unstated founding at the end of M37. It was created to counter the threat of the 7^th Black Crusade in 811.M37, when Abaddon the Despoiler and his forces assaulted the Segmentum Obscurus. Since their inception, the Baleful Boars have writ a blood-soaked saga of fell deeds and numerous atrocities down the long millennia of their existence. Walking a precarious path between purity and damnation, only time will tell whether or not the numerous excesses committed by the Baleful Boars in the Emperor's name will be their downfall, and eventually they are declared renegades by the High Lords of Terra.
Bears of the Claw		Imperium of Man (Fidelitas Sine Recursu)	Ferrus Ursus	A feral and Chapter created during the 20^th Founding from uncertain lineage, this Chapter only numbers 700 Astartes. Despite their smaller size, their ferocity and stubbornness in the face of overwhelming odds, more than makes up for their lack of numbers.
The Betrayed		Ruinous Powers (Traitoris Perdita)	Might of Santiro	The Betrayed is a relatively new Chaos Warband whose pirating ways are proving to become more dangerous for the Imperium with each passing year. Until 950.M41, The Betrayed was known as the Sworn of Guilliman, the sole known successor Chapter of the Metamarines. Since the near annihilation of the Chapter in the events the now-rebellious Astartes call the Betrayal, The Betrayed is slowly drifting toward 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.
Black Knights		Imperium of Man (Fedelitas Tenebrae)	Wrath of Caliban	The Black Knights are an ancient and proud Loyalist Space Marine Chapter created from the lineage of the secretive and mighty Dark Angels Legion of old. They were created during the Second Founding following the dissolution of the Space Marine Legions after the events of the Horus Heresy. A fleet-based crusading Chapter, 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, interrogated, and granted extreme unction. As a crusading Chapter, their doctrines, traditions, and organisation reflect their particular approach to prosecuting the Imperium's wars. The Black Knights are wont to become embroiled in battles that other forces would have little hope of winning. They are unrelenting in their persecution of the Emperor's foes, reserving a particular loathing for the Traitor Legions and those who make truck with the Ruinous Powers. The Black Knights absolutely refuse to retreat in the face of any foe, however, this stubbornness has often come at a high price. The Astartes of this Chapter are grim and dour, with all their warriors wearing battle-plate of jet-black and deep red. Extant reports, however, indicate that this Chapter wields all manner of ancient relics and holy patterns of armour, weapons, and vehicles not commonly seen on the battlefields of the modern era.Imperium's wars.
Black Reapers		Imperium of Man (Fedelitas Scindere)	Bastion of Hope	The Black Reapers are a semi-Codex compliant Loyalist Space Marine Chapter of an unknown gene-seed, having much of their ancient history having been lost. They heavily favour the usage of terminators in combat, and as such, they have become venerated items in the chapter's armoury, alongside their dreadnoughts. They roam the stars in their massive star fortress the Bastion of Hope, forging a reputation for helping individuals in strife, even going against orders of authority to help those in strife, and many people who fight for the imperium look to the skies in times of trouble, awaiting the time when drop pods should rain down, delivering the Emperor's justice.
Blade Spectres		Imperium of Man (Fidelitas Tenebrae)	Ever Shade	The Blade Spectres are a Loyalist Space Marine Successor Chapter descended from the lineage of the shadowy Raven Guard. They are a newer Chapter comprised entirely of newly-revealed Primaris Space Marines. They were created as a part of the recent Ultima Founding to take part in the Indomitus Crusade and to stand as a bulwark against the enemies of Mankind.
Bladehounds		Imperium of Man (Fedelitas Scindere)	Sword of Conquest	The Bladehounds are a loyalist Space Marine Chapter founded during the Ultima Founding as a fleet-based chapter. Offically they are descended from the venerable First Founding White Scars, but studies of their gene-seed and tactics have left unfortunate rumours to circulate about them. The Bladehounds are known for their martial skill in close-combat, with most battle-brothers of the chapter being reputable chain-sword duelists, and are noted members of the Tempestus Wardens, a coalition of chapters founded in the aftermath of the Ruinous Crusade.
Blades of Onyx		Flexible as they are mercenaries for hire. Will not take contracts that bring them into conflict with the Imperium of Man. (Fedelitas Tenebrae)	Anabasis	The Blades of Onyx are a mysterious band of mercenary Astartes that have exiled themselves from the Imperium and sell their services to Rogue Traders and various xenos races. Their origins are unknown to the modern-era Imperium, however some Imperial scholars point to extant records and various eye-witness accounts, placing them throughout various events that have occurred throughout Imperial history for the last ten millennia. This would mean that their true origins more than likely harken back to the dark days of the Horus Heresy during the Age of Darkness.
Blades of Resurgence		Imperium of Man (Fidelitas Totalis)	Loyalty Unbound	The Blades of Resurgence are one of the many loyalist and Codex-compliant space marine chapters created from the gene-seed of Rogal Dorn, primarch of the Imperial Fists. Born from the much-neglected 17^th Founding, the Blades of Resurgence are perhaps one of the most noble and valiant space marine chapters to have ever existed. However, they do have a hatred of the also prideful Reclaimers of Dorn, creating a little rift between various factions and organisations of the Imperium.
Blades of the Lion		Imperium of Man (Fedelitas Scindere)	Chimaera	The Blades of the Lion are a 3^rd 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.
Blood Bearers		Imperium of Man (Fedelitas Totalis)	Crimson Death	A venerable 3^rd Founding Blood Angels Successor Chapter, the Blood Bearers are an extremely reclusive Chapter, but are stoutly bound to their Progenitors. Unusually, they do not deny their blood-lust, and in turn have learned to embrace, it, thus, achieving an unparalleled level of restraint of their genetic curse.
Blood Guard		Imperium of Man (Fedelitas Constantus)	Emergency	The Blood Guard are a 11^th Founding Successor Chapter created from the lineage of the stoic and unforgiving Iron Hands. Upon their inception this Chapter was assigned the task of searching out and eliminating the heretic, the traitor, and the xenos. They have a high success rate with less collateral damage. Seeking out and purgation of these threats is not all that they are capable of, and often, the Blood Guard is called upon to intervene in various Imperial crusades and conflicts.
Blood Hunters		Imperium of Man (Fedelitas Constantus)	Red Howl	The Blood Hunters are a loyalist Space Marine Chapter formed during an unknown founding. While it is known they are descended from the Sanguinius, due to lost history, it is unknown which chapter they are successors of directly. Originating from the death world of Nionus, the Blood Hunters Chapter has trained their new recruits in the aggressive way of their people trained to hunt and eliminate their enemies with extreme brutality. Using aggressive stealth tactics to break down the enemy's defenses before fast striking waves of marines charge the enemy. They tend to favor close-quarters combat but are known to use ranged attacks to harass the enemy as well.
Blood Scorpions		Imperium of Man (Fedelitas Totalis)	Kargatane	A 6^th Founding Successor Chapter of the noble Blood Angels, the Blood Scorpions are a brutal and savage Chapter that adamantly believe in Mankind's manifest destiny to vanquish all the vile and wicked alien races and claim their rightful place as the true inheritors of the galaxy.
Blood Wyverns		Chaos Undivided (Traitoris Maximus)	Ancalagon	The Blood Wyverns are a notorious Chaos Warband in the service of Chaos Undivided. They were formerly a Loyalist Chapter of the ill-fated 21st 'Cursed' Founding going by the same name. They presumably come from the gene-stock of Roboute Guilliman, though this remains unconfirmed. Despite the fact there were no physical or mental defects with this Chapter, the fear and suspicion of the Imperium had caused them to go rouge when the Blood Wyverns had come to blows with an Inquisitorial Task Force. For the sin of daring to attack representatives of the Inquisition, they were declared renegades. Making their retreat to the farthest edges of Segmentum Pacificus, the Blood Wyverns soon turned to Chaos, however the Warband prefers to keep Chaos at arm's length.
Bloodsworn	Pict-File Unavailable	Themselves (Traitoris Perdita)	Fiery Massacre	The Bloodsworn are a formerly Loyalist Space Marine Chapter created from unknown lineage during the 4^th Founding in the middle-centuries of M32, following the near-disastrous War of the Beast. Tragically, this Chapter's service to the Emperor of Mankind was very brief, as after only a few decades, there were reports of this Chapter's overzealous prosecution in their duties, leaving formerly rebellious worlds as bloody abattoirs in the wake of their planetary assaults. After being declared renegades, this Chapter has embraced their status as outcast, launching periodic raids against Imperial merchant vessels and isolated worlds. They also work as mercenaries for hire for unscrupulous heretics. (Traitoris Perdita)
Blue Hand		Tzeentch (Traitoris Maximus)	Purity of Knowledge	The Blue Hand Chaos Space Marine Warband are a small force of Traitor Astartes born of the former Loyalist Chapter of the same name. Being few in number, the Blue Hand have sought to raise heretical cults on worlds across the Ultima Segmentum. Such cults are known as The Cult of the Blue Hand of Tzeentch. They are dedicated to the Chaos God of change, as are the Blue Hand Marines, and incorporate the Warband’s eponymous sigil into their iconography. The Blue Hand Space Marine Chapter was a respected loyalist force for millenia, before their fall to Chaos. Now, those few Imperials who know of their existence speak their name with the deepest scorn and the fiercest hatred.
Bolts of Dorn		Imperium of Man (Fedelitas Totalis)	Fist of Koorland	The Bolts of Dorn are semi Codex-compliant Successor Chapter created from the proud stoic and stalwart Imperial Fistss during the 4^th Founding in the mid-500s.M32, following the end of the infamous War of the Beast. The Chapter was created as an expansion to rebuild many lost chapters of Imperial Fists lineage and other 2^nd and 3^rd Founding Successor Chapters. The Bolts of Dorn was also created to counter myriad threats from the Segmentum Ultima, be it the Forces of Chaos from the Maelstorm or the marauding Orks and the newly emerged Necrons and T'au Empire.
Bone Reapers		Imperium of Man (Fedelitas Scindere Recurso)	Ossus Damnatio	The Bone Reapers are a Loyalist Successor Chapter created from unknown genetic lineage in late M40, during the 25^th 'Bastion' Founding. Formerly known as the Revenant Lords, this young and bellicose Chapter soon garnered an infamous reputation for savage displays of barbarity and unsubstantiated rumours of bloody rituals. After several centuries of such behaviour, they were formally censured by the High Lords of Terra. It wasn't until 910.M41, that the Chapter's true nature was brought to light, revealing them as inheritors of Sanguinius. Slowly accepting their progenitor's traditions and customs, the Chapter still struggle to curb the worst excesses of the Chapter's inherited warrior culture and blood practices.
Brazen Bulls		Imperium of Man (Fedelitas Totalis)	Concord of Steel	The Brazen Bulls were a 21^st 'Cursed' Founding, Codex-compliant chapter founded right before the Age of Apostasy from the lineage of the merciless and unforgiving Iron Hands. Originally meant to patrol an area of space north of the Eye of Terror, the Bulls arrived along with another Cursed Founding chapter, the Fell Hands. The two fleet-based chapters cut down on raiding activity in the region for centuries, even managing to skirmish with forces on the edge of the Eye of Terror itself. However, even the resources of two Astartes chapters were spread thin in several sectors, and with the Age of Apostasy in full force the Fell Hands and Brazen Bulls were largely left on their own. After the Fell Hands eventually turned renegade, the Brazen Bulls fought against their former allies and battle-brothers, eventually scattering them into the Eye of Terror at the cost of their own chapter.
Brazen Lions		Imperium of Man (Fedelitas Totalis)	Lion's Pride	A mysterious 13^th 'Dark' Founding Successor Chapter created from the genetic lineage of the formerly loyalist Astral Claws Chapter. The Brazen Lions have operated as a fleet-based Chapter since the destruction of their Chapter homeworld during the Age of Apostasy. Despite the aspersions and acrimony often displayed towards them, the Brazen Lions continue to stoically carry on, determined to raise themselves above the sins of their genetic forebears.
Brethren of Hel		Chaos Undivided (Excommunicate Traitoris)	Malleus Infernum	A formerly loyalist 2^nd Founding Chapter known as the Iron Invictors, their obsession with certain forbidden mysteries and nightmarish sciences of the Dark Age of Technology saw them being declared Excommunicate Traitoris and cast out of the Imperium. Renaming themselves the Brethren of Hel, this fleet-bound Chaos warband now periodically raids Imperial forge world and far-flung Adeptus Mechanicus outposts near the Eye of Terror- obsessed with obtaining rare STCs and the secrets of archaeo-technology.
Bringers of Change		Tzeentch (Excommunicate Traitoris)	Enlightenment	This notorious Chaos was a formerly loyalist Chapter known as the Grey Gorgons, created during the 25^th Founding from the lineage of the unforgiving Iron Hands. They were led into damnation by the Chapter's former Chief Librarians, which resulted in a Chapter-wide schism. Now they ply the space lanes near the Eye of Terror, bringing misery and death to those the followers of the 'Corpse Emperor'.
Broken Wings		Imperium of Man (Fedelitas Constantus)	Momento Sanguinius (Destroyed)	The Broken Wings were a semi Codex-compliant Chapter descended from the lineage of the heroic Blood Angels. They were an ancient and venerable Chapter who has valiantly served the Emperor of Mankind throughout the existence of the Imperium. Although officially their Founding is Unknown, they supposedly dated back to the Great Crusade and Horus Heresy eras. Alas, after millennia of faithful service, the Broken Wings fell on Baal Secundus where they sacrificed themselves to bring down a vast number of a massive Tyranid swarm of Hive Fleet Leviathan in 999.M41.
Bulls of Retribution		Imperium of Man (Fedelitas Totalis)	Minotaur's Fist	The Bulls of Retribution are a Loyalist Successor Chapter descended from the lineage of the stoic and proud Imperial Fists, raised in 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.

Name	Allegiance	Flagship	Notes
Cadian Wall	Imperium of Man (Fedelitas Totalis)	Kraf Bastion	The Cadian Wall are an Imperial Fists Successor Chapter formed during the Ultima Founding at the behest of Rouboute Guilliman so that they may take part in the Indomitus Crusade. As steadfast and as hardy as their namesake, the Cadian Wall Chapter are true sons of Dorn.
Caustic Reach	Imperium of Man (Fedelitas Constantus)	The Maw	The Caustic Reach are a small Adeptus Astartes Chapter created during the 21^st Founding, the so-called 'Cursed Founding', from existing (presumably Raven Guard) gene-seed which was modified to counteract the high potency of Tyranid poisons and toxins these foul xenos commonly employed. Given the gene-seed the scientists managed to create a genetic resistance to the Tyranid poisons and toxins via unprecedented mutation which causes an overproduction of toxins and poisons within these Astartes bodies, which are then transferred to the Betcher's Glands within their mouths, causing them to 'drool' these poisons uncontrollably. This Chapter currently stands at approximately 350 Astartes, their forces severely depleted at the hands of Hive Fleet Kraken, though their exact numbers remain uncertain.
Celestial Stars	Imperium of Man (Fidelitas Totalis)	Sons of Penance	The Celestial Stars is a Space Marine Successor Chapter known for its adherence to the Codex Astartes. They trace their origins back to the Shield Bearers, a previous Chapter whose members were sent on a hundred-year penitent crusade. Upon completing their penance, these veterans formed the initial command cadre of the Celestial Stars. The exact time of the Chapter's founding remains uncertain. Throughout its history, the Chapter has gained recognition for its courageous deeds and selfless sacrifices among its fellow Chapters. The past experiences have instilled in the Celestial Stars an unwavering determination to atone for the actions of their brethren, which fuels their zealous pursuit of redemption. The support of like-minded chapters has bolstered their resolve as they continue their battle across the vast expanse of the cosmos, confronting both familiar and unfamiliar adversaries.
Cerberus Chapter	Imperium of Man (Fedelitas Constantus)	Hesperos Theos	The Cerberus Chapter are a loyalist non-Codex compliant Chapter created during the recent Ultima Founding and comprised entirely of newly revealed Primaris Space Marines - the stage of evolution of the Adeptus Astartes. Primarily fleet-based, this aloof and mysterious Chapter keeps to themselves, preferring to wage their own private war against the enemies of Mankind. Rarely, does this Chapter fight alongside other forces of the Imperium, and on the rare occasions that they do, they prefer to keep their own counsel and wage their campaigns as they see fit, only reporting to Imperial command to inform them of their progress.
Champions of Mortis	Imperium of Man (Fedelitas Constantus)	The Indomitable Spirit	The Champions of Mortis are an ancient, semi-Codex compliant Successor Chapter of Adeptus Astartes created during the 3^rd Founding from an unknown sire. This Chapter is currently located in the southern fringe of the Imperium of Man, and they have devoted themselves to fanatically target and purge Heretic Astartes emerging from the Scourge Stars, especially those of the hated Death Guard Traitor Legion.
Chiroptera Legion	Imperium of Man (Fedelitas Tenebrae)	Tenebraxis	The Chiroptera Legion are a mysterious and enigmatic Loyalist Adeptus Astartes Chapter created during an Unknown Founding and from uncertain descent, but it is believed to early. Imperial scholars speculate this Chapter to have possibly been created as early as the 2nd Founding, following the end of Great Scouring in 021.M31. They are inhuman monsters, vicious and violent beyond what is expected even of Astartes, their armour covered in macabre images of death and terror. These vicious Astartes have even been compared to the murderous Night Lords Traitor Legion, and the similarities between them have led many to claim that it is more than just coincidence, for unlike other Chapters that bring hope to worlds, the Chiroptera Legion does not come to liberate, they do not come to save - they come to bring judgement and to punish.
Chogorian Outriders	Imperium of Man (Fedelitas Sine Recursu)	Gaera	The Chogorian Outriders are an Ultima Founding Successor Chapter of the elusive White Scars, comprised entirely of newly revealed Primaris Space Marines.

Claws of Arktos	Imperium of Man (Fidelitas Sine Recursu)	Ferus Unguis (Star Fortress)	The Claws of Arktos are a Loyalist Space Marine Chapter created from the ferocious Bears of the Claw. These bellicose and fierce Astartes were created during the 23^rd Founding, the so-called 'Sentinel' Founding, as a part of a series of linked Foundings that took place during the latter part of M37. The Claws of Arktos are one of several Chapters tasked to take and hold the Aliris Sector, located to the galactic south of Cadia in a star rich part of the Segmentum Obscurus, to stand sentinel against attacks by the Forces of Chaos from the Eye of Terror. Claiming the isolated death world of Arktos as their own, the Chapter garrisons the planet from above in their ancient star fortress Ferus Unguis.
The Condemned	Imperium of Man (Fidelitas Totalis)	The Clink (Flagship)	The Condemned are an ancient and venerable Chapter supposedly created during the Second Founding as a rare Successor Chapter of the Raven Guard following the end of the Horus Heresy and subsequent Great Scouring. In an effort to make better use of incorrigible youth whom were often toughened, resilient children, a progressive amongst the High Lords of Terra decreed that he would demonstrate that enforcing the Pax Imperialis could provide an even greater benefit to the Imperium. He did this by creating a specialist Chapter with recruits drawn from the Imperium's criminal youth. Named the Condemned, this newly formed Chapter was expected by many not to last a single generation, however, this chapter of child thieves, gangers and murderers has instead prevailed through the annals of time in obscurity and against adversity, proving that reformation and redemption can be found in service of the Emperor in glorious battle and, ultimately, in death.
Crimson Prowlers	Imperium of Man (Fidelitas Sine Recursu)	Red Shroud	The Crimson Prowlers are an Ultima Founding Successor Chapter of the mighty and powerful Space Wolves, comprised entirely of Primaris Space Marine. They are a part of a whole line of descendant Fenrisian Chapters - the 'Sons of Russ' - to help stand sentinel over the Eye of Terror and stand as a bulwark against the Forces of Chaos.
Crimson Robes	Imperium of Man (Fedelitas Totalis)	Coeptis Sapientiae	The Crimson Robes were a Loyalist Successor Chapter of the stoic Imperial Fists, raised at the beginning of M32 during the 3^rd Founding. Highly regarded for their siege capabilities and the arbiters of a number of impressive victories, this promising young Chapter was seemingly wiped out just over a millennia after its inception, but later returned to the Imperial fold, temporarily, nearly three millennia later. However, the Chapter's bad luck continued to dog them, as they had the misfortune to cross paths with a massive Ork WAAAGH!, only to be utterly annihilated.
Crimson Vanguard	Imperium of Man (Fidelitas Totalis)	Swordhaven Bastion	The Crimson Vanguard are a Loyalist Chapter that was created in the Ultima Founding as one of the Successor Chapters of the White Scars. Early in the chapter's history, the Chapter found records that were written by the Ancient Terran samurai and in order to pay homage to these warriors, the Crimson Vanguard decided to adopt their culture.
Crusaders Inexorable	Imperium of Man (Fidelitas Totalis)	Vigil Eternal	Founded during the 8^th Founding, the Crusaders Inexorable have over the millennia gained a reputation for being inexhaustible, never ceasing in their hunt against the enemies of The Imperium. They have proven in the past to be rather isolationist when it comes to their fighting, often refusing aid, always opting to fight on their own rather than trust any other force when possible. Originally as a chapter their propensity for fighting alone was likely through some strange form of pride or repentance, perhaps for their first Chapter Master's failure in their first independent battle, but over time this disposition has been strengthened by repeated betrayals from close allies.
Crystal Dragons	Imperium of Man (Fedelitas Constantus)	Gaping Maw	The Crystal Dragons are a Loyalist Space Marine Chapter of the Adeptus Astartes created during the 25^th 'Bastion' Founding, specifically for the purpose of supervising other chapters' penitent crusades. The Iron Hands lineage was chosen for their strong adherence to logical thought and reason over passion and feelings. In their short story, the Crystal Dragons have already accompanied over 20 of such crusades, treating those under their surveillance with cordiality yet cold severity to make sure that those Astartes atone for their past sins against the trust of the Emperor.

Dark Hosts		Imperium of Man (Fidelitas Tenebrae)	The High Halls	The Dark Hosts are a Loyalist Successor Chapter of the Dark Angels. Created during an Unknown Founding, they were made up of particularly revanchist members of the Dark Angels Legion who sought to maintain the traditions of the Hexagrammaton and the duty of their Primarch Lion El'Jonson to scour the darkest corners of the galaxy of the most dangerous threats to the Imperium. The Dark Hosts are a calculating and relentless force that have been on crusade across the galaxy since their founding, highly trained and exceptionally equipped for all styles of warfare to meet the challenge of their endless vigil. They wander from campaign to campaign across the stars as a grim reminder to the galaxy of the time when the Dark Angels were the Emperor's Exterminators.
Dawn Lords		Imperium of Man (Fedelitas Sine Recursu)	Gloriae Illustrata	The Dawn Lords are a Loyalist Successor Chapter created during an unknown founding from the lineage of Primarch Jaghatai Khan. This Chapter has a short history due to their recent founding by the Imperium's acting Lord Commander. Their Firstborn brothers, on the other hand, have a long battle record extending back to M34. Much of the original Dawn Lords' story has been forgotten, although incomplete records indicate that they are an offshoot of the Destroyers Successor Chapter. What is known is that they were assigned to patrol the northern reaches of the Segmentum Obscurus and were last heard to be operating at full strength prior to the advent of the event known as the Noctis Aeterna. Their subsequent fate is unknown, but the Primaris brothers of the refounding hope to find word of their lost brothers' status. The search will have to wait. Since assuming their duties, the Dawn Lords have endured terrible losses to the rising tide of the alien, the heretic, and darkness within the Imperium Nihilus.
Dawn's Wolves		Imperium of Man (Fedelitas Constantus)	Fenrisian Dawn	The Dawn's Wolves are a rare Successor Chapter of the Space Wolves comprised entirely of Primaris Space Marines. 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.
Death Flowers		Imperium of Man (Fedelitas Sine Recurso)	Northern Dragon	The Death Flowers are a Loyalist Successor Chapter of the Black Lotus Chapter which was created during the ill-fated 13^th Founding, the so-called 'Cursed' Founding.

This Chapter was assigned with searching and destroying Necron tomb worlds.
Diamond Knights		Imperium of Man (Fedelitas Totalis)	Diamond Keep (Star Fort)	The Diamond Knights are an 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.
Doom Hunters	Pict-File Unavailable	Traitoris Perdiat (Officially) Imperium of Man (Actuality)	Fury of the Damned (Space Hulk)	The Doom Hunters are a Loyalist Space Marine Chapter of unfortunate and mysterious origin, and very few outside of the chapter know it and live for very long after learning their secrets. Officially, this Chapter are well-hated traitors within the Imperium, classified as a renegade chapter who sided with the traitors by pure necessity for survival. In a "clever scheme" by the Inquisition, the Doom Hunters "feigned" betrayal at the behest of certain Inquisitorial parties in order to destroy the heretics from the inside. These parties remained the Chapter's only contacts and connection to the Imperium that they still secretly served. Mostly. However, now that their secret is revealed, there is no need for subterfuge.
Dragons Sanguine		Imperium of Man (Fedelitas Totalis)	Bleeding Hand	The Dragons Sanguine were a Successor Chapter of the vaunted and noble Blood Angels.

Drakes of Deathfire		Imperium of Man (Fedelitas Totalis)	Breath Of Deathfire	The Drakes Of Deathfire are an ancient and honourable Loyalist Successor Chapter of the Salamanders whose exact founding is unknown. However, the Chapter maintains they are one of the original Successor Chapters created in 021.M31, following the dissolution of the original Space Marine Legions, which were broken down into smaller formations known as Chapters, consisting of only 1,000 Astartes each. Despite the Drakes claims, Imperial savants have been unable to determine the veracity of such claims, though they have been mention in several extent accounts down the long millennia of the Imperium's historical archives. The Drakes of Deathfire are a crusading, non-Codex compliant chapter, meaning they do not follow the dictates of the Codex Astartes. The Drakes Of Deathfire believe heavily in the Promethean Cult and center themselves around bringing Nocturne's light and warmth to the imperiums citisens and those in it unable to defend themselves, and its, the God-Emperor's and Vulkan's rage, fury, and flame upon the alien, mutant and the heretic.
Dread Hands		Imperium of Man (Fedelitas Constantus)	Black Leviathan	The Dread Hands are a Loyalist chapter of Space Marines that were created in the 4^th Founding, - following the War of the Beast - this Chapter is descended from the stoic and unforgiving Iron Hands.

Ebon Host	Imperium of Man (Fedelitas Tenebrae)	The Ebon Blade	The Ebon Host is a Successor Chapter of the venerated Angels of Absolution, a chapter from the lineage of the I^st Legion - the Dark Angels. The Ebon Host can root its creation during the 13^th Dark Founding, a founding from which few chapters can definitively trace their inception to. Like their forebears, they do not consider themselves amongst the Unforgiven, believing they have done more than enough to repent in the eyes of the Emperor, and the Lion. The Ebon Host adopted many ways from their forebears however refused to incorporate the unique 1^st and 2^nd Companies, instead staying Codex-compliant, for a time. It was not three centuries after their founding that their entire chapter seemed to change, traditions stripped away and replaced, seemingly changing their organization for little reason, and the abandonment of any hope to settle their chapter, instead using a newly acquired vessel as their Fortress Monastery. However, the most drastic of changes was their abandonment of their fellow Sons of the Lion, as if they had done wrong by the Ebon Host.
Ember Sharks	Imperium of Man (Fedelitas Sine Recursu)	Ark of the Furance	The Ember Sharks are a Loyalist Space Marine Chapter created during an Unknown Founding, hailing from the lineage of the Primarch Corvus Corax. Since at least the middle centuries of M31, this bellicose Chapter has sailed the Outer Dark in the Segmentum Obscurus, silently watching for any threats that may come. In their mobile fortress-monastery, the Ark of the Furnace, a Chapter Barque, the Chapter continues their eternal vigil, silently watching and waiting for any threats that dare assails the realm of Mankind. That the Ember Sharks come from the gene-line of Corax is unquestioned, yet they are of brooding countenance, and utilize brutal terror tactics in order to cripple the foes of the Imperium before they are slaughtered by the vengeful marines of this Chapter.
Emperor's Legion	Imperium of Man (Fedelitas Totalis)	Colossus	The Emperor's Legion are an ancient and proud Loyalist Successor Chapter created from the lineage of the Primarch Roboute Guilliman, created during an unknown founding. Steeped in deep traditions and ancient practices, this Chapter resembles the culture of Old Earth's Romanii in a lot of similar ways. They are very organised and strict in their ways of war and have earned a reputation as merciless and fearless warriors in battle. Despite being a Successor Chapter of the Ultramarines, the Astartes of this Chapter are strict adherents of the worship of the Imperator as a God, but are not officially a part of the Ecclesiarchy.
Emperor's Reapers	Imperium of Man (Fedelitas Scindere)	Tombstone	The Emperor's Reapers are an ancient whom can supposedly trace their inception to the Second Founding, however, verifying such claims is all but impossible due to the passage of millennia and human error. Their exact lineage is unknown. Extant reports indicate that the Emperor's Reapers excel in close-quarters actions, utilising a wide variety of close-range weapons, especially the bygone (and often shunned) power scythe.
Epsilon Tempests	Imperium of Man (Fedelitas Totalis)	Resolution	The Epsilon Tempests are a Successor Chapter of the vaunted Ultramarines. Founded during the recent Ultima Founding with the introduction of the Primaris Space Marines.

Eternity Invictors	Imperium of Man (Fedelitas Totalis)	Indefatigable	The Eternity Invictors are a Loyalist Successor Chapter descended from the proud lineage of the stoic Imperial Fists, created during the 25^th Founding, the so-called 'Bastion Founding'.

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 the 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.
Ferrus' Children	Imperium of Man (Fedelitas Totalis)	Ferrus' Head	Ferrus' Children are a Codex Astartes-compliant Loyalist Successor Chapter of the unforgiving Red Talons, who themselves are descended from the lineage of their unforgiving and stoic Primarch Ferrus Manus.

Due to unforeseen circumstances, the First Captain of the Fists Exemplar was forced to align with an Iron Warriors Battalion to survive an attack by a massive greenskin fleet. Choosing to align themselves with their Iron Warriors allies, these Fists Exemplar Astartes further damned themselves when their commander killed a fellow Scion of Dorn the High Marshall of the Black Templars. This decision forced Zerberyn and his followers to walk the path of the traitor forevermore. Some but few of the Fists Exemplar disagreed with Zerberyn, most notably Captain Arcos of the 4^th Company. Captain Arcos and what remained of his company left knowing they could not simply go back to the Imperium. These former Fists Exemplar eventually became the Fists Revenant.
Flesh Rippers	Imperium of Man (Fedelitas Sine Recursu)	Death's Herald	The Flesh Rippers are an infamous and savage Chapter of unknown origin or Founding, though many believe their origins hearkens back as far as the 2^nd Founding.

Due to several incidences of massacres being committed by this Chapter, there have been calls to have them excommunicated, but thus far, they have managed to avoid this fate,for now...

Very little is known in the way structure of the chapter as they have no particular homeworld on record, making them officially a crusading chapter. However there have been a multitude of records of these Astartes engagements as interestingly their fleets arrive when an Imperial Crusade is collapsing or when Imperial Hive Worlds are under siege. This leads some to speculate them to be a successor chapter of the Salamanders due to the selfless nature in defending Imperial lives. However upon examination of some of their fallen there were no visible mutations in their gene seed commonly seen within the sons of Vulkan. Afterwards upon questioning to an Apothecary of the chapter as he collected the gene seed of the fallen, demanding to know of who they were. The Apothecary only responded with the words 'Pulvis et umbra sumus' meaning "We are but dust and shadow," in High Gothic.

Gold Knights	Imperium of Man (Fidelitas Totalis)	Beacon Of Light	The Gold Knights is a Loyalist Successor Chapter of the Adeptus Astartes created during an unknown Founding and from an uncertain genetic lineage. There is little information in official Imperial records regarding this mysterious Chapter's origins or when they were created.

Gorgons of Extinction	Imperium of Man (Fidelitas Constantus)	Krataios	The Gorgons of Extinction is an ancient, storied Loyalist Successor chapter created during the 4th Founding sometime in the mid-500s.M32, descended from the gene-seed stock of the stoic and unforgiving Iron Hands' Primarch Ferrus Manus in the decades following the disastrous events of the War of the Beast, against the largest Ork WAAAGH! seen since the time of the Great Crusade led by the mysterious Greenskin Warlord known only as The Beast.
Graven Skulls	Imperium of Man (Fedelitas Tenebrae)	(To be added)	The Graven Skulls are a mysterious and horrifying, nightmarish force of power-armour clad spectres, whose lineage and exact Founding remains unknown, though many suspect their origins harken back to the ancient 2^nd Founding. Mystery and suspicion attach themselves to these dour and macabre warriors who often shun fighting alongside other Imperial forces, that, and their reputation for using deadly and forbidden weaponry long-thought to have been destroyed millennia earlier, has earned them a frightful reputation amongst both enemies and allies.
Gray Hussars	Imperium of Man (Fedelitas Totalis)	The Emperor's Sabre	The Gray Hussars is a Loyalist, Codex-divergent Space Marine Chapter from the 26^th Founding. They descend from the gene-line of Rogal Dorn, Primarch of the stoic Imperial Fists.

Grey Wolves	Imperium of Man (Fedelitas Sine Recursu)	Torngasak	The Grey Wolves are a Successor Chapter of the Space Wolves created during the Ultima Founding, consisting entirely of Primaris Space Marines.

Honour Mauls	Imperium of Man (Fidelitas Constantus)	The Bolt of Censure	The Honour Mauls are a fleet-based Successor Chapter of the Excoriators. They were originally created as an experiment during the ill-fated 21^st 'Cursed' Founding to study the effects of genetic modifications made on another Primarch's gene-line, in an effort to cure the Excoriators' mutation.

Host of Aiakides	Imperium of Man (Fedelitas Totalis)	Unknown	The Host of Aiakides is a Fourth Founding Space Marine Chapter of Rogal Dorn's lineage, created when another Imperial Fist Successor Chapter, the Phrygian Knights, as with all chapters that were alive by then, was ordered to supply a portion of their veterans to found a new Chapter in the aftermath of the War of the Beast.

Hounds of Kerberos	Imperium of Man (Fedelitas Scindere)	(To be added)	The Hounds of Kerberos are an ancient and bellicose Chapter whose legendary savagery has earned these notorious Astartes a fell reputation across the width and breadth of the Imperium.

Imperial Wardens	Imperium of Man (Fedelitas Totalis)	Unknown	The Imperial Wardens is a Loyalist, semi-Codex compliant, Space Marine Chapter alleged to be ancient born from either the Second or Third Founding. The Imperial Wardens is a fleet-based chapter that follows a rare fusion between Crusade and Pilgrim patrol patterns across the Imperium. As they believe themselves to be the "Red Right Hand" of the Emperor, it's their right to patrol the galaxy in search for enemies, often boasting to have been at every corner of the Emperor's domain. The Chapter is known for its almost monastic behavior, from their recognizance of the Imperial cult to their adherent of the Imperial Creed, characterized for their intense reflection and study of the teachings of the Emperor and their Primarch Rogal Dorn. This by itself compels the Wardens to fanatically hunt and burn down any trace of heresy or betrayal against the Imperium, especially against the Forces of Chaos.
Incursors	Imperium of Man (Fedelitas Constantus)	The Faltriesh	The Incursors are a Loyalist, Codex-compliant Space Marine Chapter of unknown origins created during the 23^rd 'Sentinel' Founding. This fleet-based Chapter is an isolated and often reclusive Chapter that rarely works alongside other Imperial military forces or fellow Adeptus Astartes Chapters, and are often accused of being accused of being haughty or lacking in brotherhood. This is mainly due to their neverending Crusade to bring to light of the Emperor to the darkest corner of the galaxy, and despite their isolationist tendencies, this Chapter has continuously defended the realm of the Emperor of Mankind, earning a proud and enviable record of valour and service, comparable to other more senior Chapters.
Inheritors of Caliban	Imperium of Man (Fedelitas Tenebrae)	Lion's Will	The Inheritors of Caliban are a Codex Compliant Chapter created in the Ultima Founding descended from the venerable Dark Angels. Though a noble and pious Chapter, their name hides a dark secret few of them are privy to. The Inheritors of Caliban did not just inherit the genetic legacy of Lion El'Jonson, but the dark secrets hidden by the Dark Angels. As part of the Unforgiven, the Inheritors of Caliban are a shadowy and reclusive force indeed; seeking to redeem the First Legion's honour at any cost. In battle they favour strong fire lines and lightning assaults to slay a foe as quickly as possible before moving on to the next.
Iron Gorgons	Imperium of Man (Fedelitas Totalis)	Hammer of Medusa	The Iron Gorgons are a Second Founding Successor Chapter of the stoic and unforgiving Iron Hands. An unassailable and resolute Chapter, they are a notoriously bellicose Chapter whose battle tactics are almost entirely concerned with the application of overwhelming force to bring about the total and immediate destruction of their foes. They serve as a part of a triumvirate of Second Founding Iron Hands Successors known as the Frateris Firmitatis.
Iron Myrmidons	Imperium of Man (Fedelitas Totalis)	Determinatio Machinis	The Iron Myrmidons are a mostly Codex-compliant Imperial Fists Successor Chapter from the 4^th Founding, after the disastrous War of the Beast, with a focus on Zone Mortalis combat & siege warfare. They are a proud and tenacious chapter, rarely devolving into savage or overly brutal conduct but instead are an unrelenting tide of adamantium & ceramite sending precise volleys of bolter fire into their foes while vehicles and heavy specialists move ahead.
Iron Purity	Imperium of Man (Fedelitas Constantus)	Redemption's Stars	The Iron Purity are an ancient and stalwart Loyalist Successor Chapter created from the proud lineage of the Ultramarines, supposedly created as early as the 2^nd Founding, following the bloody civil war of the Horus Heresy and the subsequent Great Scouring.

This Chapter is comprised entirely of Primaris Space Marines, created during the most recent Ultima Founding. As a fleet-based Chapter, the Iron Seraphs are highly active at prosecuting the wars of the Imperium against the myriad of enemies of Mankind. Like their fellow Unforgiven Chapters, the Iron Seraphs are driven to prosecute the Dark Angels' secret war against The Fallen, and are more than willing to answer their progenitors' call to war in order to achieve their objectives.
Iron Sights	Imperium of Man (Fedelitas Totalis)	Legacy of Iron	The Iron Sights are a Successor Chapter of the stoic and unforgiving Iron Hands. Created during the 9^th Founding, they are renowned throughout the Imperium for their extreme marksmanship and heavy firepower. Unlike many Space Marine Chapters they tend to eschew hand-to-hand combat, choosing instead to annihilate their enemies with devastating hails of bolts, plasma, and lascannon fire. While their lack of hand-to-hand combat estranges them from some chapters, such as the zealous Black Templars, it has allowed them to forge some mutually beneficial alliances with close combat oriented chapters such as the Angels of Rebirth.
Iron Strategoi	Imperium of Man (Fedelitas Totalis)	Unknown	The Iron Strategoi are a non-Codex compliant Ultima Founding Chapter, released from the stasis vaults of Archmagos Dominus Belisarius Cawl. Who led the Lord Regent Roboute Guilliman to believe this Chapter were sons of Ferrus Manus 'The Gorgon'. However, these staunch defenders of the Imperium know their real heritage, and keep the secret close to their chests, doing much to prevent those who have prying eyes like those of the Inquisition from discovering these truths until the time is right. Though supposedly successors of the Gorgon they are siege and heavy weapons specialists, as well as capable architects. These Marines are no strangers to fortifying locations and assisting destroyed worlds to rebuild their homes. Many of the Iron Strategoi have augmentations though not as many as their respected Iron Hands counterparts, they as well rely on a higher number of Techmarines and large amounts of heavy tanks such as the Astraeus Super-Heavy Tank.

Juggernauts		Imperium of Man (Fidelitas Constantus)	Unstoppable Chariot)	Born during the 21^st 'Cursed' Founding, the Juggernauts are often referred to as the 'Inviolable Tide' and, true to both their nickname and the name of their Chapter, the warriors of the Endless Crusade are a terrifying and seemingly numberless foe. Obstinate in the extreme, it is near impossible to dissuade a Juggernaut from their chosen course, come death or come the Emperor's personal command, they will never retreat, no sacrifice too great in their quest to eradicate the Master of Mankind's enemies.

Keepers of the Accord		Imperium of Man (Fedelitas Tenebrae)	Unknown	The Keepers of the Accord are a Loyalist Chapter of the Adeptus Astartes shrouded in mystery and symbolism, thus worthy successors of the Dark Angels and their Primarch Lion El'Jonson. Presumably - like their forebears and brother Chapters, the Keepers are part of the Unforgiven - the brotherhood of Chapters that hunt the Fallen Angels. However, they are distant from their fellow Unforgiven, not because of a grudge or spite, but because of their creation. Despite the tactic approval of the High Lords of Terra the Chapter's creation, their inception is mired in classification and mystery. What is known is that the Keepers have always stood vigil over a wandering planetoid named "Thessalon" from a great space station acting as their Fortress Monastery of Caelestis Castellum. The Keepers of the Accord maintains a rather high number of Techmarines among their ranks, and thus have an impressive quantity of Land Raider patterns in their armory.
Kharonean Martyrs		Imperium of Man (Fidelitas Tenebrae)	Psychopompós	The Kharonean Martyrs is a loyalist Chapter of the Adeptus Astartes, created during the 18^th Founding, though the exact date of their inception has been lost to the shifting tides of time. They belong to the gene-line of Lion El'Jonson, which makes them a part of the Unforgiven successors of the Dark Angels Legion. They are, for the most part, adherent to the structures of the Codex Astartes, though many of their methods are somewhat unorthodox when stood beside other Space Marine Chapters. Whenever the Chapter comes to the aid of a beleaguered system or fights alongside other Imperial forces, they will demand compensation for the blood they shed. To replenish the high numbers of men, equipment, and other resources they expend, the officers of the Kharonean Martyrs will name a steep price to whoever possesses the means to pay them. It is merely their due reward, for a debt incurred through the sacrifice of Astartes lives, and so they feel little shame about taking what is rightfully theirs.
Knights Angelicus		Imperium of Man (Fedelitas Totalis)	Shield of the Morning Star	The Knights Angelicus are a venerable chapter of the ancient Second Founding coming forth from the remains of the 50th Chapter of the noble Blood Angels. They are a proud and noble chapter that value the honor of brotherhood while also valuing the lives of their brothers as dictated by the Stygian Oath all members of the chapter take when they join the chapters ranks. It is upon these ideals and beliefs as written down in the oath that dictates the actions and choices taken by chapter members when it comes to their brothers.
Knights Celestial		Imperium of Man (Fedelitas Constantus)	Tears of Joan	Created during the mysterious 13^th 'Dark' Founding, this stalwart Dark Angels Successor Chapter is based in the Ultima Segmentum near the infamous warp anomaly known as the Maelstrom. They have continued to uphold their martial traditions of honour and chivalry despite the destruction of their Chapter homeworld, displaying a strong desire to slay the heretic forces of the Ruinous Powers.
Knights Despoilers	Pict-File Unavailable	Imperium of Man (Fedelitas Obscurus)	Zealous Rampant	Created during the 26^th Founding, the Knights Despoilers were created as a Successor Chapter of the Red Crusaders, whose lineage is unknown. Striking from the void relentlessly and eager to punish the unworthy, the Knights Despoilers embody the fervent zeal of their foster chapter, the Red Crusaders. The Knights exploit these terror tactics to quickly disencourage most opposition, being specialists in dealing with planetary rebellions and cultist uprisings.
Knights Seraphic		Imperium of Man (Fidelis ad Mortem)	The Black Seraph	The Knights Seraphic are a Successor Chapter of the heroic Blood Angels, created during the 9^th Founding. This vexatious and mysterious Chapter were formally sanctioned by the High Lords of Terra for dabbling in dark rituals and having a penchant for tech-heresy. To atone for their crimes they were forced to embark upon a penitent crusade by Imperial authorities. Steeped in secrecy and accused of anti-Imperial sentiment, this Chapter of monastic esotericists wander the stars trying to piece together the history of their order.
Knights of the Fist		Imperium of Man (Fedelitas Scindere)	Dorn's Graal	The Knights of the Fist are a crusading Successor Chapter descended from the proud lineage of the stoic Imperial Fists. Once known as the Knights of Caledon upon their inception, they formerly derived much of their doctrine from the example of the Black Templars, however, they have since developed their own direction, especially in the post-Tenebris era. The Chapter stands on the precipice of loyalty and apostasy. Following the resurrection of Guilliman, his appointment as Lord Regent, and the subsquent Indomitus Crusade, the Chapter's formerly Codex-skeptical outlook has become more extreme. The Chapter is now openly hostile to Guilliman and Ultramarines successors, but nonetheless professes its loyalty to the Emperor.
Kraken Reavers		Imperium of Man (Fidelitas Sine Recursu)	Kraken's Rorar	The Kraken Reavers, known as the 'Víkankrak' in their tongue, are an Ultima Founding Successor Chapter created from the lineage of the savage Space Wolves. This brutal Chapter is comprised entirely of Primaris Space Marines, the next stage of evolution of the Space Marines. Their inception took place in the wake of Abaddon the Despoiler's 13^th Black Crusade in 999.M41. The Kraken Reavers were created as a void shock-assault force, to patrol around the Eye of Terror and the Great Rift to keep in check the Traitor Legions who use it to launch raids across the imperium. As well as any other enemies of mankind who sail within imperial space.
Kraken Scythes		Imperium of Man (Fidelitas Sine Recursu)	The Reaper's Tendril	The Kraken Scythes are an eccentric and reserved chapter of the Adeptus Astartes descended from the lineage of Roboute Guilliman's Ultramarines through the 3^rd Founding Scythes of the Emperor. They were created during an unknown founding after the assault on Miral Prime in order to get revenge on the Tyranids in the Eastern Fringe. They are adamant believers in the Imperial Truth and are highly isolated from other chapters. The Kraken Scythes perceive themselves as having the singular purpose of revenge against the Tyranids for the attack on Dantris III and to hunt down and root out Genestealer Cults. The Chapter bears a loose alliance with their presumed parent Chapter, the Scythes of the Emperor.

Lions Malevolent	Imperium of Man (Fedelitas Tenebrae)	Undying Vengeance	The Lions Malevolent are a Successor Chapter of the line of Primarch Lion El'Jonson, supposedly created during the 5^th Founding sometime during M33. 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.
Lion's Praetorians	Imperium of Man (Fedelitas Tenebrae)	Angel's Wings	The Lion's Praetorians are an ancient 3^rd Founding Successor Chapter created from the lineage of the venerable and mysterious Dark Angels. Both in doctrine and temperament, the Lion's Praetorians are very similar to their Progenitors, and the two Chapter's teachings are largely consistent. Shunning fame and laurels, the deeds of the Lion's Praetorians are even less well-known than those of the other Unforgiven Chapters, however, they are incredibly zealous and honorable and are devoted members of the Unforgiven (the collective of Dark Angels Successor Chapters), concentrating on their duties to the exclusion of all else.
Lion's Regents	Imperium of Man (Fedelitas Tenebris)	Banshee of Caliban	The Lion's Regents, also known as the Kings of the Lion & the Leo Astra or Space Lions, are a fleet-based loyalist Space Marines chapter created during the 3^rd Founding using geneseed taken from the secretive Dark Angels and are part of the Unforgiven. As their name implies the chapter sees itself as carrying on the will of Lion El'Jonson, sometimes causing friction with other members of the Unforgiven who are seen as acting in their own interests over what the Lion would do. Even their primogenitor chapter is not above being accused of acting out of character for their shared father, currently Azrael & Colm have an understanding though historically they tend to get at each other's throats easily, as such they are not a very popular member of the Unforgiven.
Lycaean Liberators	Imperium of Man (Nominally) (Traitoris Perdita)	Shattered Chain	The Lycaean Liberators were originally a fleet-based Raven Guard Successor Chapter created during an unknown founding. They were declared heretical for their actions against local governmental assets, but they consider themselves to be still loyal, though they are increasingly distressed by the discrepancy between the state of the Imperium and the ideals of their Primarch Corvus Corax.
Lycanthropes	Imperium of Man (Fedelitas Totalis)	Jürgensburg	The Lycanthropes are a savage and mysterious Space Marine Chapter created during the 21^st 'Cursed' Founding from unknown lineage. This chapter of Adeptus Astartes teeters on the edge of the Ordo Astartes' tolerance. Brutal and mindlessly violent on the battlefield, they have garnered a grim reputation of carnage and bloody retribution. With no planet to call their own the Lycanthropes are an insular chapter, their offerings of the enemies blood made both to their unknown Primarch (many theorising it to be Leman Russ) and the God-Emperor.

Mandators	Imperium of Man (Fedelitas Totalis)	Unknown	The Mandators are a Loyalist Codex-compliant Space Marine Chapter created during the recent Ultima Founding from the proud and heroic lineage of the Ultramarines. They are comprised entirely of newly revealed Primaris Space Marines, the next stage of evolution of the transhuman warriors of the Adeptus Astartes. This Chapter has close ties to the Inquisition in the Aurum Sector.
Manticores	Imperium of Man (Fidelitas Scindere)	Relentless Fury (Ramillies-class Star Fortress)	The Manticores are a supposed Renegade Chapter created during the ill-fated 21^st Founding, the so-called 'Cursed' Founding. They were created from the lineage of the ancient and mysterious Dark Angels. Near the end of M40, this Chapter was declared 'Renegade' by the High Lords of Terra for unknown reasons. It is believed they had come into conflict with the Inquisition. Rather than reveal the secrets of the Unforgiven, they willing accepted their discommendation, though they still loyally serve God-Emperor and the people of His Imperium.
Marines Baleful	Imperium of Man (Fedelitas Tenebrae)	Umbra Vigilemus	The Marines Baleful are a 15^th Founding Dark Angels Successor Chapter, one with a dark and shrouded history. Originally known as the Angels of Valiance, a proud and arrogant chapter obsessed with their own superiority. However, after their arrogance nearly became their downfall, the chapter underwent drastic changes to its structure, livery, and and culture, renaming themselves the Marines Baleful. They have since become a mysterious and potent force against the enemies of the Imperium, striking fear into the hearts of their foes.
Martyrs Vindicant	Imperium of Man (Fedelitas Scindere)	Angel's Wrath	The Martyrs Vindicant were a semi-Codex compliant Blood Angels Successor Chapter established during the 15^th Founding sometime in M35, upon the death world Helis in the Segmentum Ultima. The Chapter would become famed for its fanatical hatred of Orks, often abandoning battlefield objectives and even dooming entire campaigns in an attempt to slaughter any greenskin presence the chapter became aware of. Helis would remain the Chapters' home world until the late years of M38, when an apocalyptic Ork WAAAGH! drove the Martyrs from the planet, forcing them to roam the stars as a fleet-based chapter. The Martyrs would roam the stars of the galaxy until 999.M41, when during the fleets speedy journey to Baal during the Third Tyrannic War, the Cicatrix Maledictim - a massive tear in reality that stretched across the width of the galaxy - flinging the entire Chapter fleet into the depths of Warp space.
Megalodons	Imperium of Man (Fedelitas Sine Recurso)	Navka	The Megalodons are a Loyalist Space Marine Chapter created during an Unknown Founding and from uncertain lineage. This savage and merciless Chapter were reputedly created in antiquity, but their exact origins are difficult to pinpoint by Imperial scholars, remaining shrouded in the midsts of long-lost antiquity, thousands of years in the past. An isolationist and aloof Chapter, the Megalodons have continuously prosecuted their solitary crusade for millennia, bringing the light of 'Monatoa', 'The Void Shark that Devourers' (God-Emperor), to the darkest corners of the galaxy. Like hungry apex predators, they stalk through the cold, dark depths of the void, striking their foes unexpectedly and tearing them apart, then slip back into the Outer Dark. The Megalodons' ruthless reputation has writ a bloody legacy across the pages of Imperial history, their very name having become synonymous with merciless butchery of those who would dare assail the realm of Mankind.
Mordekaisers	Imperium of Man (Fedelitas Totalis)	Morgen Schwach (Imperial Star Port)	The Mordekaisers (translated to High-Gothic as 'Murder Lords') are a Successor Chapter created as a 24th Founding of the Imperial Fists. The Mordekaisers' duty is the guarding of the Ghoul Stars where they reside in the Imperial Starport Morgen Schwach ('Morrow Dim'), located near the Malefactus Rift. They specialise in lightning fast assaults that take out multiple enemy targets in rapid succession as well as void operations. Their tendency to wear battle damage is a symbol of the Chapter's years of enduring hardship that would've wiped out countless other Chapters; a testament to the endurance of the Mordekaisers.
Mortarchs Serpentia	Imperium of Man (Fedelitas Tenebrae)	Jormugundr	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.

Nameless Stalkers	Unknown	Mercenary's Reward	The Nameless Stalkers are a non-Codex compliant Space Marine Successor Chapter created from an unstated lineage. It is believed that the Chapter was originated from an altered stock ("Chimeric") composed of gene-seed from both the Raven Guard and the Iron Hands, during the 12^th Founding in mid-M35. However, this hasn't been definitively proven, and due to the Chapter's nomadic nature, has been extraordinarily difficult for the Magos Biologis to obtain adequate gene-seed samples for study.
Night Guard	Imperium of Man (Fedelitas Totalis)	Black Caiman	The Night Guard is a Loyalist Chapter, that is shrouded in mystery. Created during the mysterious 13^th Founding, the mysterious 'Dark Founding'. Little is known about this obscure Chapter, only when they were created and that they are formidable void warfare specialists and are almost unbeaten in this realm of conflict. They tend to go out in the void in special hardened armour and drift towards an unsuspecting enemy vessel.
Night Ghosts	Imperium of Man (Fedelitas Terribilis)	Navis Horribilis	The Night Ghosts are a Loyalist Space Marine Chapter of the ill-fated 21^st 'Cursed' Founding. They are one of the most feared chapters of the noble warriors of the Adeptus Astartes. But what most people do not know if they read the many reports of the satanic tortures of the Night Ghosts are that the Chapter follows the honourable regulations of the Cult Prometheus from the noble Salamanders with the same fanaticism. And even less know the second face of the Night Ghosts - a friendly albeit very reserved mind. Whatever imperial organisations think about the Night Ghosts, one thing no one can deny - wherever the Night Ghosts fight in a war the losses to civilians number close to zero. If a tyrant enslaves innocents or criminals who rob the population, no wrong can survive against the Night Ghosts.
Night Ravens	Imperium of Man (Fedelitas Tenebrae)	Raven Song	The Night Ravens are a Raven Guard Successor Chapter created during the 21^st 'Cursed' Founding. Despite their genetic idiosyncrasies, the Night Ravens have managed to forge a reputation for melding stealth and guile with vigilance, swiftness and perseverance. But despite their loyal and faithful service, they are often shunned by many of their fellow Adeptus Astartes.
Nightscream	Imperium of Man (Fedelitas Tenebrae)	Shadowfall	The Nightscream are a mysterious Successor Chapter created from the lineage of the Raven Guard during the ill-fated and oft-maligned 21^st Founding, the so-called 'Cursed Founding'. The Chapter ended up suffering from a debilitating flaw that affected their vision, which rapidly worsened until the affected battle-brother was rendered completely blind. However, this unnatural blindness has resulted in them developing far superior senses than even a standard Astartes - superior hearing, an enhanced sense of smell, tastes and acute sensitive touch.

Obsidian Blades	Imperium of Man (Fedelitas Tenebrae)	Lament of Crastus	The Obsidian Blades are a Codex-deviant Successor Chapter created from Raven Guard gene-stock during the often ill-maligned 21^st 'Cursed' Founding. Their genetic 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.
Obsidian Shadows	Imperium of Man (Fidelitas Constantus	Stygian Eclipse	The Obsidian Shadows is an all-Primaris Raven Guard Successor Chapter that was created in the Ultima Founding for the sole purpose of ruthlessly destroying Chaos Cults that are hidden within Imperial planets. Due to their skills and expertise in dismantling these cults when they arise, this chapter created an alliance with the Ordo Hereticus as this Inquisitorial Faction is dedicated to the same goals as this chapter.
Omniscions	Imperium of Man (Fedelitas Constantus)	Omni-Temple	The Omniscions is a Loyalist Codex-compliant Successor Chapter created sometime during M36 during an Unknown Founding from the lineage of the stoic and unforgiving Iron Hands. Like their genetic forebears, the Omniscions are well known for their fanaticism of the Cult Mechanicus.
Onyx Blades	Imperium of Man (Fedelitas Tenebrae)	Triumph of the Void	The Onyx Blades are a Loyalist Space Marine Successor Chapter created from the lineage of the ancient and aloof Fist Founding Dark Angels. However, despite their claim as being created during the mysterious 13^th Founding, the so-called 'Dark Founding', official records are incomplete and fragmentary. Debate still rages into the modern era, whether or not the Onyx Blades were created during this mysterious Founding.
Onyx Executioners	Imperium of Man (Fedelitas Sine Recursu)	Ashen Cross	The Onyx Executioners are a foreboding and mysterious fleet-based Chapter, supposedly created during the 23^rd Founding, the so-called 'Sentinel Founding', from unknown genetic lineage. Originally known as the Crusaders of Glory, this Chapter garnered a reputation as being a humane and pacivistic Chapter that had a reputation for sparing their enemies instead of outright destroying them, often turning them over for interrogation to agents of the Inquisition. However, their merciful nature would prove to be their undoing. In the early decades of M41, the majority of the Chapter become corrupted by the Ruinous Powers, and the Chapter fell into internecine conflict. However, in the end, the loyalist faction emerged triumphant. To further distance themselves from their treacherous former kin, they changed their heraldry, iconography and Chapter name to the Onyx Executioners.
Owls of Judgement	Imperium of Man (Fedelitas Tenebrae)	Judgement of Corax	The Owls of Judgement are a loyalist, semi-Codex compliant Space Marine Chapter, comprised entirely of Primaris Space Marines. They were created to fight the myriad of Chaos uprisings springing up throughout Imperium Nihilus the in the wake of the formation of the Cicatrix Maledictum. Unlike most sons of Corax, the Owls are myopic, bellicose, paranoid, and obsessed with enacting their own sense of justice on each planet they pacify. These trials can last months, or even years, as the Astartes attempt to narrow down who is responsible for the uprising, and punish them accordingly. Since the beginning of the Fourth Tyrannic War, they have also begun to persecute Genestealer Cults.

Paladins of Caliban	Imperium of Man (Fidelitas Constantus)	Vengeance of Caliban	The Paladins of Caliban are a Successor Chapter created from the lineage of the ancient and mysterious Dark Angels. As they're an Ultima Founding Chapter, they're composed entirely of Primaris Space Marines. As a member of the Unforgiven, they've learned their progenitor chapter's secrecy and, as such, have been known for being extremely secretive towards their allies during battles or campaigns.
Panthers of Kiavahr	Imperium of Man (Fidelitas Tenebrae)	Shadow Claw	The Panthers of Kiavahr are a Successor Chapter of the Raven Guard, sons of the great Primarch Corvus Corax. They have been created during the Ultima Founding, composed entirely of the newly unveiled Primaris Marines. The Panthers of Kiavahr are a fleet-based Chapter and their flagship is called the Shadow Claw. Like Raven Guard they are masters of stealth and hit-and-run attack, however they are considerably more aggressive and brutal than their progenitors.
Patriarchs of Iron	Imperium of Man (Fidelitas Totalis)	Unknown	The Patriarchs of Iron are a Loyalist Space Marine Successor Chapter descended from the lineage of the stoic and unforgiving Iron Hands. They are a newer Chapter comprised entirely of newly-revealed Primaris Space Marines. They were created as a part of the recent Ultima Founding to take part in the Indomitus Crusade and to stand as a bulwark against the enemies of Mankind.
Penitent Gates	Imperium of Man (Fidelitas Tenebrae)	The Walls of Caliban	The Penitent Gates are a loyalist non-Codex compliant chapter founded during the 21^st 'Cursed' Founding from the gene-seed of the Dark Angels at the end of M35. The Gates are part of the Unforgiven, the collection of Dark Angels successors dedicated to hiding the heretical past of the I^st Legion. The Penitent Gates consider themselves cursed from the fall of Caliban, and as such take a vow of anonymity and silence upon progression to the ranks of their chapter. A Penitent Gate battle-brother (Knight) will never show their face or speak out loud even to another brother of the Unforgiven until the fateful day they see their penance complete.
Phantom Knights	Imperium of Man (Fedelitas Totalis)	Constantius	The Phantom Knights are a now-extinct loyalist Codex-compliant Space Marine Successor Chapter created from the lineage of the legendary and feared Dark Angels during an unstated founding in 831.M33. They were founded as a fleet-based Chapter with the task of patrolling and securing the utmost border areas of Segmentum Obscurus, the region of Imperial space to the galactic north of Terra.
Pilgrims of Sanctus Penitents	Imperium of Man (Fedelitas Totalis)	The Ancient of Days	The Pilgrims of Sanctus Penitents is a very small and unique non-Codex compliant Chapter composed of Space Marines from several different Chapters. The Chapter is on an eternal crusade, following the rare Pilgrim-Pattern, traveling to all known Shrine Worlds in the galaxy. Spreading the Imperial Cult throughout the territory of the Imperium. And smite all heretics and traitors along the routs, in the name and with the fury of the Emperor. Thousands of sinners and heretics together with hundreds of fanatic preachers, devoted missionaries and redemptionists follow the Chapter on its crusade through the void.
Polar Flares	Elementi World Fleet (Traitoris Perdita)	The Apocalypse Carrier	The Polar Flares are a 4^th Founding and rare Successor Chapter created from the lineage of the shadowy Raven Guard. This Chapter was formerly located in the Polaris Sector, but has turned renegade and accompanied the 'Crusade of Renegades' trek to the Solarain Sector, where they meet with the abhumans known as the Elementi.
Protean Vipers	Imperium of Man (Fedelitas Totalis)	Unknown	The Protean Vipers are a Loyalist fleet-based Space Marine Chapter of uncertain founding and origin. It has been involved in numerous campaigns across the Imperium with notable, heavy involvement in the Indomitus Crusade. The culture of the Protean Vipers is one of self-reliance and independent thought to the point that commanders will often consider the opinions and carry out strategies devised by their subordinates. However, this is only possible due to the strict, efficient command structure that is then used to carry out the battleplan once decided on. The Vipers are well known for maintaining good relations between many chapters and have been documented in helping ease relations between rival chapters.
Praetorian Guard	Imperium of Man (Fidelitas Totalis)	Intrepidus	Founded at the onset of the Indomitus Crusade, the Praetorian Guard is a Successor Chapter of the venerable Ultramarines. The Intrepidus, their fortress-monastery, stands as a mighty Ramilies-class Starfort. Little do the Praetorian Guard know that this grand structure, shrouded in the mists of history, once belonged to a loyalist splinter faction of the hated Emperor's Children. It was during the tumultuous era of M32 that this enigmatic faction vanished, leaving behind a legacy of mystery and unanswered questions. Unbeknownst to the present-day Praetorian Guard, the Intrepidus carries the hidden remnants of its loyalist Emperor's Children origins, serving as a silent testament to the obscured history of their chapter.
Prædicators	Imperium of Man (Fedelitas Totalis)	Cetus (Ramillies-class Starfort)	The Prædicators Chapter was created around the time of the mysterious event known as the Year of Ghosts from their genetic forebears – the Silver Skulls – whom themselves were descended from the proud and heroic lineage of the ancient Ultramarines Legion. Sharing as they do the genetic inheritance and many of the traditions of the Ultramarines, the Prædicators are above reproach. In many ways, however, the Prædicators are very different to the other inheritors of Guilliman's legacy. The Astartes of the Prædicators are overtly maudlin in demeanour, with many brethren appearing to be consumed by morose thoughts of nihilistic tendencies. However, they have learned to channel this darkness via their rites and traditions into a formidable weapon with which to engage the enemies of Mankind.
Purifiers	Excommunicate Traitoris	Cleansing Wrath	Of all the horrific enigmas spawned by the 21^st 'Cursed' Founding, the Purifiers are perhaps the most terrifying. Like most born during that dark time, these Astartes did not last long. Though others such as the Blood Gorgons succumbed to either corruption in their minds, bodies or both, the madness of the Purifiers was something deeper, something the Imperium at large could little understand. Exemplary even by the nightmarishly high standards of the Adeptus Astartes, the mystery of the Purifiers' extermination will eternally puzzle those few who know of them. (Excommunicate Traitoris)

Rampart Boars	Imperium of Man (Fedelitas Scindo), Imperial tithe territory "Realm Ikrell" (Fidelitas Sine Recurso)	Cataegian Conviction	The Rampart Boars, known as the 'Xargha'Khai-ne' in their own language, is a Loyalist Chapter of the Adeptus Astartes created during the 3^rd Founding in the year 003.M32, a few short years after the start of the noted founding of the early 32^nd Millenium from the lineage of Jaghatai Khan. The Ordo Astartes consider the Rampart Boars to be a valuable asset in the destruction of xenos threats, particularly the prevention of and even removal of Orks from planets and the destruction of Genestealer Cult threats from Hive Fleet Orthrus. The initiates of the chapter are known for being tall, with abnormally thick bones and a large oddly proportioned musculature from genetic inclusions they refer to inaccurately as "atavisms". Their physical strength is covered with only a thin veneer of nobility over their savage, and often unstable minds.
Raven Sons	Imperium of Man (Fidelitas Scindere)	Unknown	The Raven Sons are a Codex-compliant fleet-based Successor Chapter of the Raven Guard created during the Ultima Founding, ca.999 M41. They were created to serve as a buffer force to the Astra Militarum, often being deployed onto the same battlefields to "eliminate" enemy leaders and supply lines. They also support the overall firepower of the forces of the Astra Militarum. The chapter is known for its non-standard recruitment system, often taking young Aspirants from saved imperial worlds, calling them the "warborn", believing these children were born to fight. This often raises disputes within singular squads as it's hard to get people of different worlds and cultures to adapt to the same strategies and views of warfare quickly.
Redeemers	Imperium of Man (Fedelitas Totalis)	Unknown	The Redeemers are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the rare lineage of the Raven Guard and raised during the Ultima Founding of ca. 999.M41. Created as a chapter to watch potential new threats coming from outside the Milkyway Galaxy, the Redeemers keep their eyes in any events enveloping the Eastern Fringe. Their actions usually take them against both Ork forces and Tyranids.
Retributors	Imperium of Man (Fedelitas Totalis)	Unknown	The Retributors are a Loyalist Successor Chapter of the stoic Imperial Fists, created during an unknown Founding. Since their inception they have continuously stood stalwart in the face of myriad threats to the Imperium of Man, including hordes of foes, cunning witchcraft and terrifying unknown technologies. The Chapter primarily operates along the borders of the Eastern Fringe. This Chapter has been described as distant, relentless and efficient by those fighting alongside them as the Retributors are a stern and austere Chapter, more interested in battlefield success than glory and accolades.
Ruiners	Imperium of Man (Fedelitas Totalis)	The Fortress of Decimation	The Ruiners are a semi-Codex compliant Space Marine Chapter of the Adeptus Astartes comprised entirely of newly revealed Primaris Space Marines created during the Ultima Founding. They bear the gene-seed of Primarch Ferrus Manus of the grim and unforgiving Iron Hands. While this Chapter does maintain their parent Chapter's close ties with the Adeptus Mechanicus, they do not share in their beliefs in the weakness of the flesh.

Sable Pride		Imperium of Man (Fedelitas Tenebrae)	Supreme Judgement	The Sable Pride is a semi-Codex compliant successor of the venerable and ancient Dark Angels Chapter, that was founded in order to hunt down a specific Fallen during M37. The Prides' history has been fraught with misfortune and treachery as they have sought to complete their duty to the Emperor and the Lion. The chapter even suffered its own civil war known as the War of the Two Prides, which damaged the psyche of the chapter and caused a slow turn away from the Unforgiven, who they now hold a tenuous relationship with, completely ignoring the word of the Supreme Grand Master and even firing upon fellow chapters. Despite this, the Pride still hunts the Fallen, but places far more importance on capturing their own traitors from the warband, Dothanes Pride.
Sanguine Templars		Imperium of Man (Fedelitas Constantus)	The Cleansing Spear	The Sanguine Templars are a venerable and ancient Successors Chapter of the sacred bloodline of the angelic Primarch Sanguinius, gene-sire of the heroic Blood Angels, created during the Second Founding in 021.M31. Formerly, they were known as the 7^th Company of the original IX Legion. Rather obsessed with cleansing themselves of the old Legion's sins, taking every moment they weren't on the battlefield or training, to meditate on their misdeeds. To study in-depth the teachings of Sanguinius and to harness their bloodlust into a weapon. To be the noble angels their father desired.
Scarred		Imperium of Man (Fedelitas Sine Recursu)	Kini'je	Known amongst the Imperium of Man as the 'Wolves of Jochi', the Scarred are a wild and frenzied 3^rd Founding Successor Chapter of the White Scars. Infamous for the almost elemental devastation their presence brings to the battle, having embraced their ancestral war-frenzy driving, the brooding Scarred allow it to propel them ever onward like the bone-chilling storms of the tundral Jochi. Like their progenitors, the Scarred are masters of lightning-fast assaults, appearing suddenly in bellows of fury, their coming heralded by the skies darkened and unnatural blizzards beginning to lash the battlefields.
Sea Serpents		Imperium of Man (Fedelitas Constantus)	The Leviathan	The Sea Serpents are a non-Codex compliant Chapter of Space Marines whose exact Founding and lineage are unknown, although some Imperial scholars hypothesize their origins harken back to the dark days of the Horus Heresy to a similarly named Loyalist Blackshield force. Known for their use of terror tactics, infiltration and asymmetrical combat strategies, they've made a name for themselves as a fearsome and elusive tool of the Imperium that swiftly destroys their enemies before they can even mount a defense.
Seraphim of the Abyss		Imperium of Man (Fedelitas Scindere)	Shadow of Loyalty	The Seraphim of the Abyss are a mysterious and ancient semi-Codex Compliant Dark Angels Successor Chapter from the 2^nd 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.
Shades of Cog		Imperium of Man (Fedelitas Constantus)	Unknown	The Shades of Cog are a semi Codex-compliant Space Marine Chapter believed to have been raised as part of the 11^th Founding in 900.M35 in response to the extreme civil conflict and unrest in the Imperium. The chapter was created to assist their White Scars ancestors in countering the threats in the Segmentum Ultima.
Shattered Star		Imperium of Man (Fedelitas Sine Recursu)	The Storm Queen	The Shattered Star are a Loyalist Space Marine Chapter believed to have been created from unknown lineage during the 21^st 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.
Shenandoah Knights		Imperium of Man (Fedelitas Totalis)	Sea King	The Shenandoah Knights is a Loyalist Successor Chapter created from the lineage of the vaunted and stoic Imperial Fists during the 25^th Founding, the so-called 'Bastion Founding'. A fleet-based Chapter, the Shenandoah Knights lay no claim to any one world. However, they have appointed themselves as guardians of the Shenandoah sub-sector located in the Segmentum Obscurus. Maintaining a network of chapter keeps throughout the sector, these stalwart defenders have stood silent vigil over their chosen demesne for millennia protecting it from threats both within and without. Like their progenitors, the Shenandoah Knights are also believers in the divinity of the God-Emperor, and as such, they maintain strong ties with the Ecclesiarchy as well as a close relationship with the Adepta Sororitas, most notably, the Order of the Emerald Rose. However, due to their adherence to the Imperial Creed, they often clash with other Chapters of the Adeptus Astartes who do not share their beliefs.
Silver Centurions		Imperium of Man (Fedelitas Totalis)	Pride of Brigandium	The Silver Centurions are a loyalist, Codex-compliant Successor Chapter that hails from the proud lineage of the honourable Ultramarines. Created during the mysterious 13^th 'Dark' Founding, this fleet-based, crusading Chapter travels in a vast armada that ventures throughout the Imperium to fight the foes of Mankind.
Silver Fists		Imperium of Man (Fedelitas Totalis)	Arx Argentum	The Silver Fists are a Chapter formed of Primaris Space Marines created from Rogal Dorn's gene-seed. Having studied the tactics of the Imperial Fists, the Crimson Fists and even the Black Templars chapters that were available, they began to develop their own strategies to intervene in both xenos and traitor attacks on populated worlds and valuable locations.
Silver Hands		Imperium of Man (Fidelitas Scindere)	Dauntless Shroud	The Silver Hands ('Manus Argenti' in High Gothic) are Chapter from unknown lineage, founded during the 13^th Founding as a fleet based chapter, following a nomadic pattern, their role is to reinforce other imperial forces in time of need on the battlefield. Stoic and proud, they are also known for being merciless and sometimes excessively violent.
Silver Shards		Imperium of Man (Fedelitas Totalis)	The Hallowed Choir	The Silver Shards are a Loyalist Space Marine Chapter descended from the Primarch Rogal Dorn and successors to the honourable and proud Imperial Fists Chapter, with their founding being held during the 4^th Founding in the 500s.M32. Currently, the Silver Shards are a fleet-based Chapter, with its main operation being in northern Segmentum Ultima, however, several crusades have been declared prior and presently that took the Chapter into the Eastern Fringe and Segmentum Obscurus, where the ruins of their homeworld reside.
Sin Eaters		Imperium of Man (Fedelitas Totalis)	Unknown	The Sin Eaters are a non-Codex complient chapter of Successor Chapter of the ancient and honourable Blood Angels, created during an Unknown Founding. They are noted as a highly superstitious chapter, holding the curses of Sanguinius's gene-seed with religious reverence. It is their belief that, by interpreting the mad ravings of those afflicted with the Black Rage, the chapter can glean insights into the lingering grace and wisdom of their primarch.
Snow Lions		Imperium of Man (Fedelitas Totalis)	Prae Vistor Omnis	The Snow Lions are a Loyalist Space Marine Chapter of the Adeptus Astartes and a Successor Chapter of the proud and stubborn Imperial Fists. Created during the 25^th Founding, or 'Bastion Founding', in 501.M41. The Snow Lions have a short (comparatively) but violent history. A fleet-based chapter created for the purpose of safeguarding an endangered Imperium, the Snow Lions have faced off against a myriad of Mankind's enemies. Their heavy use of armoured vehicles has helped to keep losses to a minimum in a time period where safety was never assured. A fleet-based Chapter, the Snow Lions are highly active in prosecuting their wars against the Forces of Chaos.
Soaring Angels		Imperium of Man (Fidelitas Totalis)	Luna Sangre	The Soaring Angels are a Loyalist Successor Chapter of the noble Blood Angels that were created during the 25^th 'Bastion Founding' in M40. A fleet-based Chapter, they strive to embody the aspect of flight and virtue of freedom that their liege-father Sanguinius set as an example to strive for. Like any other son of the Angel, flight whether by aircraft or upon roaring jump pack is a sign of devotion to their Primarch as it lets them feel as he would've felt upon the battlefield, soaring across the sky to bring down destruction upon mankind's enemies.
Sons of the Emperor		Imperium of Man (Fedelitas Totalis)	The Pious Spear	The Sons of The Emperor are a Codex Astartes-compliant Chapter that is currently engaging in a 100 year-long Penitent Crusade to pay for their past sins. They are followed vigilantly by the Crystal Dragons Chapter, responsible for supervising these golden Astartes. Although the crusade is almost over, the Sons' numbers are rapidly decaying and, without the coming of new recruits, this proud chapter may not see their reputation cleansed.
Sons of the Void		Imperium of Man (Fedelitas Constantus)	Void Reaper	The Sons of the Void are a Loyalist Space Marine Chapter created during the 23^rd 'Sentinel' Founding during the latter centuries of M37. Imperial scholars believe they were created from the proud lineage of the honorable Salamanders Chapter. They were one of several newly incepted Chapters created to help form a bulwark against encroaching xenos, especially along the frontiers of the Segmentum Pacificus against raiding Orks and the newly awakened Necron menace.
Sons of Zeus		Imperium of Man (Fidelitas Totalis)	The Silver Citadel	The Sons of Zeus are a loyalist Space Marine Successor Chapter of the stalwart and stoic Imperial Fists created during the 7^th Founding. However, some of their gene-seed share some other qualities from another unknown Primarch. These other genetic traits are suspected to have been inherited from the Ultramarines Primarch Roboute Guilliman, but inconsistencies recently with the newly received Primaris gene-seed has proven otherwise. It is now generally believed that some of their genetic heritage is shared with the White Scars Primarch, Jaghatai Khan. With this mixture of gene-seed, the Chapter is known to favour both stalwart defensive and rapid offensive tactics, often making it seem like a wave forcing sand to crash into an immovable wall. So this chapter specializes in mounted warfare, aerial and naval warfare, defensive warfare, and siege warfare as well as supporting a series of specialized combat teams similar to the Kill-Teams utilised by the xenos-hunting Deathwatch. Even sometimes donating its members to the Deathwatch and further studying them to see how they might improve against the foe.
Soul Flayers	Pict-File Unavailable	Imperium of Man (Fedelitas Tenebrae)	Blood Court	The Soul Flayers Chapter is a loyalist Successor Chapter created from the heroic lineage of the ancient Blood Angels - founded during the ill-fated 21^st 'Cursed' Founding. Like many Chapters born from the largest Founding of Space Marine Chapters since the Second Founding, the Soul Flayers are plauged with identified deficiencies in their gene-seed. Like their forebears, the Chapter is heavily fundamental in their beliefs of their Primarch, however, the Chapter views the "Flaw of Sanguinius" as a gift from the Emperor himself and sees it as a way to enter into the Imperium's Pantheon as an ordained saint. This has made the Chapter renowned for shock troop tactics, with their reliance of brute force and terror tactics by the hands of their Black Enraged Brethren.
Spectral Wolves		Imperium of Man (Fedelitas Constantus)	Naglfar	The Spectral Wolves are non-Codex adherent Chapter that was created during an Unknown Founding and from uncertain lineage. Unlike other Chapters, the Spectral Wolves do not possess the usual number of 1,000 battle-brothers, instead numbering around 700. 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. This Chapter is known for possessing an inordinate amount frost weapons compared to most other Adeptus Astartes Chapters.
Spider Lords		Renegades	Unknown	The Spider Lords are a formerly Loyalist Chapter of the Adeptus Astartes created during the ill-fated 21^st Founding, the so-called 'Cursed Founding', which was notable for a number of Chapters falling into uncontrollable and often spontaneous mutations, aberrant behavior or a susceptibility to falling to the Ruinous Powers. It is believed by Imperial scholars that the Spider Lords genetic lineage hails from the Masters of the Night Chapter, however, it is unknow from which First Founding Chapter their progenitors hail from themselves. The Spider Lords would later be declared Excommunicate Traitoris for severe mutation aberrations and barbaric practices they carried out. (Excommunicate Traitoris)
Star Crusaders		Imperium of Man (Fedelitas Sine Recursu)	Glorious Crusader	The Star Crusaders are a relative young Loyalist Space Marine Chapter founded in M39 during the 24^th Founding as a fleet-based Chapter to conduct space warfare, low/zero-g combat as well as a rapid response against enemy fleets who were able to penetrate deep into the Imperium. The Chapter's most notable battles were against the Tyranid Hive Fleet Leviathan which attacked the galaxy in two directions from below. Such an attack was the example why the Chapter had been formed and currently is engaged with the remaining part of this hive fleet.
Star Reapers		Imperium of Man (Fedelitas Tenebrae)	Axalyra	The Star Reapers are a foreboding Space Marine Chapter founded at an unknown date and are suspected successors of the venerable Raven Guard. They are a highly controversial and isolationist chapter, with a history of ruthless brutality. This Adeptus Astartes are experts of lightning-fast manoeuvres planned with a detailed complexity unseen in most Space Marine doctrine. Cloaked in a shroud of deliberate mystery and concealment likely created by agents of the Star Reapers themselves, the Chapter hides itself from the prying eyes of institutes such as the Inquisition and even other Chapters considered allies. Indeed, the only beings that know every secret of the Chapter are it's master and the Emperor Himself.
Starborn Giants		Imperium of Man (Fedelitas Tenebrae)	Unknown	Raised during the recent 24^th Founding, the Starborn Giants is a fleet-based Chapter infamous for zealously enforcing conformity throughout mankind's domains. The Chapter's belief in the Imperial Creed and the divinity of the Emperor sets it apart from other Successor Chapters of the Salamanders. The Starborn Giants' strange interpretation of the Promethean Cult causes many Salamanders successors to avoid or disown the younger Chapter. The Starborn Giants, therefore, have few allies within the Adeptus Astartes, and their austere adherence to dogma combined with their grave genetic flaws repulses much of the wider Imperium, driving the Chapter deeper into the arms of the Ordo Hereticus.
Steel Crusaders		Imperium of Man (Fedelitas Constantus)	Teigfestung	The Steel Crusaders are an 8^th Founding Successor Chapter of the stoic Iron Hands. Like their progenitors, the Steel Crusaders heavily augment themselves with numerous bionics. The Steel Crusaders are known for using heavy weapons and mechanized warfare to swiftly and efficiently sweep away enemy forces. Operating from the Star-Fortress Teigfestung, this fleet-based Chapter patrols isolated areas of the Imperium. With their mighty war-machines the Steel Crusaders bring utter ruin upon the enemies of Mankind.
Steel Scions		Imperium of Man (Fedelitas Constantus)	(To be added)	The Steel Scions are a Semi-Codex Compliant Successor Chapter of Adeptus Astartes created from the lineage of the stoic and unforgiving Iron Hands. This Chapter is located in the southern fringe of the Imperium of Man, and were created in order to specifically patrol that stretch of space and target Tyranid threats. These Sons of Gorgon are a fleet-based Chapter whose mobile Chapter fleet patrols the fringes of the Imperium, ever-vigilant for encroaching threats from the Great Devourer, and ready to meet any threat at a moment's notice.
Steel Sentinels		Imperium of Man (Fedelitas Totalis)	Frostwarden	The Steel Sentinels are a Successor Chapter of the heroic Ultramarines, created during the recent Ultima Founding, after the Unnumbered Sons were broken up into separate chapters. Preferring a full frontal assault with little finesse, the Steel Sentinels march into battle in full force, reminiscent of the pre-heresy Death Guard before the outbreak of the Horus Heresy.
Storm Griffons		Imperium of Man (Fedelitas Totalis)	Unknown	The Storm Griffons are a Loyalist Chapter of the Adeptus Astartes and supposed successor of the ever-venerable Dark Angels. There is no record of which Founding created these sons of the Lion, but the consensus amongst the Inquisition is that the Chapter was founded in mid M35, at the height of the Nova Terra Interregnum. Thrown into the fires of combat from the very beginning of their sigil to the throne, the Storm Griffons have faced against a myriad of mankind's foes. From the dark and claustrophobic walkways of floating space hulks to the wide-open expanses of tundra and death world plains, the chapter has been hardened and tempered in the fires of conflict. The chapter is fleet-based after the events that led to the annihilation of their homeworld Nyota IV in late M41.
Storm Riders		Imperium of Man (Fedelitas Scindere)	Stormsong	The Storm Riders are a Loyalist 4^th Founding and rare Successor Chapter of the highly venerated White Scars. Created during the latter years of M32, 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 Khagan.
Storm Sentinels		Imperium of Man (Fedelitas Totalis)	Hammerfall	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 25^th 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.
Stormbreakers		Imperium of Man (Fedelitas Totalis)	The Hogar	The Stormbreakers are an officially listed Successor Chapter of the stoic Imperial Fists, created during Unknown Founding. They are believed to possess chimeric gene-seed - which was somehow tampered with or somehow spliced with that of the Death Guard legion of old. The chapter sees this as a curse, and fight all the harder to redeem themselves. Secretly, there is a minor Nurgle cult within the chapter, known as the "Gifters", who are rumoured to be linked to their flawed gene-seed. The Stormbreakers are not at all Codex-compliant, possessing only 500 marines and utilising their own, unique, Chapter organisation and methods.
Stygian Krakens		Imperium of Man (Fedelitas Tenebrae)	Wrath of Kharybdos	The Stygian Krakens are a mysterious and foreboding Loyalist Chapter of the Adeptus Astartes. The origins of this aloof Chapter are as shadowy and mysterious as their dark blue battle-plate that reflects no light - just like the fathomless depths of the oceans of their former aquatic death world of Kharybdos. Imperial scholars have been unable to determine exactly when this Chapter was created, as extant records are often fractious or contradictory. A grim and morose Chapter, the Stygian Krakens prowl the starless void of the Halo Stars, emerging back into the known galaxy seemingly at random - their aid unheralded and unasked for - aiding various void-faring colonies and vessels as well as any Imperial worlds and forces they come upon. They hunt down and slaughter those that would dare encroach upon the Emperor's domain - be they xenos, heretic or daemonic.
Swarm Stalkers		Imperium of Man (Fidelitas Constantus)	Mi-Na-Wa-Tu	The Swarm Stalkers are a Loyalist semi-Codex-compliant Space Marine Chapter of the Ultima Founding. Their ranks are populated exclusively by Primaris Space Marines. The chapter was created from the gene-seed of the Novamarines with the purpose of protecting the Imperium of Man from the Great Devourer.

Teeth of the Storm		Imperium of Man (Fedelitas Totalis)	Pride of Scoanerth	The chapter of the Adeptus Astartes known as the Teeth of the Storm are a 4^th Founding Chapter created in 615.M32, following the near-disastrous War of the Beast. The Teeth of the Storm were one of several newly created Chapters created to help bring order to an Imperium rife with civil strife and insurrection, and to help restore Imperial law. Following their inception, they were charged with standing sentinel against xenos and Chaos threats in the Maelstrom Zone, the region of Imperial space surrounding the notorious Maelstrom warp rift.
Templars of Iron		Imperium of Man (Fedelitas Totalis)	Iron Will	The Templars of Iron are an ancient and bellicose 2^nd Founding Successor Chapter of the stoic and unforgiving Iron Hands. Like their genetic forebears, they too, possess an extreme hatred of the flesh and share their predilection for replacing parts of their bodies with cybernetics. They serve as a part of the ancient triumvirate of Second Founding Iron Hands Successors, known as the Frateris Firmitatis.
Templars Moline		Imperium of Man (Fedelitas Totalis)	Indomitable Will	The Templars Moline are a now-extinct Loyalist Successor Chapter created from the zealous and dedicated Black Templars, whom themselves hail from the proud lineage of the stoic Primarch Rogal Dorn. Presumably created during the 14^th Founding, sometime between 975-991.M35 as a part of several linked Foundings. Later on, they would become a part of the Hell Warders - a quintumvirate of five Space Marine Chapters tasked to defend the Imperium against Chaos incursions from the Hellgates - dual warp storms located in the Segmentum Solar which are uncomfortably close to Holy Terra. Tragically, the Chapter would meet a dire end when the entirety of their Chapter fleet disappeared into the warp rifts during the Castigation Crusade of 742.M41.
Tenebris Shades		Imperium of Man (Fedelitas Tenebrae)	The Darkness'	The Tenebris Shades are a fleet-based Loyalist Astartes chapter of an unknown Founding that hails from Dark Angels lineage, the first sign to their secretive nature, as a successor of the Angels of the Blade who supplied their initial command structure and several warships and relics to them. They are masters of covert operations as well as stealth assaults, often their allies never even know that they helped or intervened in any way.
Toxic Reapers		Imperium of Man (Fedelitas Tenebrae)	Unknown	The Toxic Reapers are a non-Codex compliant Space Marine Chapter of the ill-fated 21^st Founding, the so-called 'Cursed Founding'. Officially this Chapter was created from uncertain lineage but is suspected to be derived from Raven Guard gene-stock. They are a fleet-based chapter, their de facto fortress-monastery is the fleet known as the Reaper's Hand. This Chapter has garnered a distasteful reputation for their heavy use of stealth tactics and biological and chemical warfare involving poisons and toxins against their enemies.
Trench Walkers	Pict-File Unavailable	Imperium of Man (Fidelitas Tenebrae)	Amara Nerva	The Trench Walkers Space Marine Chapter are a loyalist non-Codex compliant Successor Chapter that was created from the lineage of the proud and secretive Dark Angels. The Chapter was founded during the recent Ultima Founding and comprised entirely of Primaris Space Marines and is a known Successor Chapter of the Dead Bells. The Battle-Brothers are recognized for their knowledge and use of biological and chemical warfare agents on battlefields across the galaxy.

Umbral Spectres	Imperium of Man (Fedelitas Totalis)	Terra's Legacy	The Umbral Spectres are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines during the most recent Ultima Founding from the lineage of the stalwart and heroic Ultramarines. Despite the tactic approval , the Chapter's inception is mired in classification and mystery.
Ultra Invictus	Imperium of Man (Fedelitas Totalis)	Gladius of Becrum	The Ultra Invictus are a lauded and seasoned Successor Chapter of the noble Ultramarines and the Avenging Son, Roboute Guilliman. Created during the venerable 3^rd Founding, the Ultra Invictus have striven to be, and upheld, the ideals of questing crusaders. Having sailed the void across the width and breadth of the Ultima Segmentum, the Chapter's brothers are regarded as laudible heroes, particularly during the 13^th Black Crusade. Being gratefully bolstered by the Ultima Founding and the induction of the Primaris Space Marines, the Ultra Invictus have sent portions of their respectable Chapter fleet to aid in the direst of wars, such as the faltering border worlds at the edge of the galaxy-wide tear in reality known as the Cicatrix Maledictum.
Umbral Wraiths	Imperium of Man (Fedelitas Scindere)	The Dark Cathedral	Created during the mysterious 13^th 'Dark' Founding, there is very little extant evidence about this mysterious and highly aloof Chapter. Initially, the Umbral Wraiths were created as a powerful and versatile xenos hunting Astartes Chapter. Their purpose was to lend to aid various wings of the Imperium, and to a lesser extent, be the sword the Imperium so desperately needed. The Chapter was to be made of Dark Angels and Raven Guard gene-seed. However, the Raven Guard's genetic material was too unstable and too precious for such an experiment, especially with the Death Spectres produced within the same Founding. As a result, the Umbral Wraiths were given; --- ##REDACTED – ORDER OF THE INQUISITION## ---

Vigil Raptors	Imperium of Man (Fedelitas Totalis)	The Cincordelum Raptorwatch	The Vigil Raptors are a Loyalist Chapter of the Adeptus Astartes and successors of the Raven Guard through the direct lineage of members of the Raptors seconded to the Deathwatch. The Chapter has been heavily involved in many of the most recent campaigns of the Fratres in Augmentationem, an alliance of Space Marine Chapters who see themselves as bearing superiority to other Astartes. As a Chapter, the Vigil Raptors have been rendered to less than twenty five percent of their chapter size twice without succumbing to extinction, but thanks to their calculating nature and a number of oddities to their gene-seed they have learned to adapt to these crises so well that they have come to flourish where others Chapters of their kind would simply fade from the histories of Imperial record.
Void Lions	Imperium of Man (Fedelitas TConstantus)	Unknown	The Void Lions Chapter-Tribe, also known as "The Great Pride", "Leonicine Inatrii" or the "Leonicines" are a loyalist chapter of Adeptus Astartes created during the 23^rd 'Sentinel' Founding in the latter half of M37 under the name of the Lion Guards Chapter. The Lion Guards homeworld was the jungle-covered Death World of Zulup IX, located deep within the Eastern Fringe. The Lion Guard chapter would lose its homeworld when the Zulup star would unexpectedly supernova, destroying the entire system. It was believed that the chapter was annihilated along with the system and were registered as a Lost Chapter. However, a chapter would emerge from the Eastern Fringe during the 41st Millennium claiming to be the survivors of the Zulup supernova incident. This chapter would be at full strength, bear different heraldry, and have a different name than the original Lion Guards chapter.
Void Paladins	To the Imperial Truth (Traitoris Perdita)	Laeraethus	The Void Paladins are a formerly Loyalist Ultramarines Successor Chapter created during the 4^th Founding, that was declared a Renegade Chapter as of M36. They are mostly a fleet-based crusading Chapter but have several planetary fortress outposts for recruiting and resupply. This Chapter follows the tenants of the Emperor's Imperial Truth and endeavours to spread this philosophy throughout the galaxy, despite their renegade status by the Imperium at large.
Void Templars	Imperium of Man (Fedelitas Totalis)	The Void's Fury	The Void Templars are a semi-Codex compliant Loyalist Successor Chapter of Imperial Fists' descent. Astartes of this Chapter are masters of void warfare, boarding actions and siege warfare. They were Founded during the 10^th Founding and are followers of the Imperial Creed, fully believing in the Emperor's divinity. They were heavily depleted from a traitor siege of their homeworld until the resurrected Ultramarines Primarch Roboute Guiliman arrived with his Indomitus Crusade and granted the sorely depleted Void Templars with newly revealed Primaris Space Marines and some additional vessels. Currently, they are participating in the Indomitus Crusade. Although they follow the Codex Astartes, they also possess their own unique ranks and Chapter traditions. They are also known for their willingness to help Astra Militarum Regiments and Imperial Navy fleets against any enemy.
Void Walkers	Imperium of Man (Fedelitas Tenebrae)	Shrouded Blade	The Void Walkers are an Ultima Founding Successor Chapter of the famed Raven Guard, comprised entirely of newly revealed Primaris Space Marines. The Void Walkers Chapter was founded in response to the creation of the Great Rift in 999.M41, serving within the legions of the Unnumbered Sons. They began their first combat action, as a Chapter, in 111.M42 in the Kaladin System to relieve the besieged capital world of Ardialan. There they continue to fight an ongoing action against a Chaos invasion of an Iron Warriors Grand Company under Warsmith Khazor.
Void Wardens	Imperium of Man (Fedelitas Totalis)	Tyrian Fury	The Void Wardens are a Loyalist Raven Guard Successor Chapter founded during the 10^th Founding in the M35.

The chapter would be nearly destroyed in its first century of existence and its current status is unknown.
Voidborne	Imperium of Man (Fedelitas Totalis)	The Tempest Eye	The Voidborne are a Successor Chapter to the White Scars. Founded during the 19^th Founding in mid-M36, their designated purpose and charge was, and still remains, to crusade on the very borders of the Imperium, deep in the cold of interstellar space where they engage the fleets of heretics, xenos, and mutants alike and bring them to ruin. A fleet-based chapter by design and choice as opposed to circumstance, the Voidborne operate almost exclusively in space and specializes in its many tactical intricacies. Void combat, boarding actions, and rapid assaults are their passion and they lean into it with all the fury and joy of their Primarch.

Wardens of Annihilation	Imperium of Man (Fidelitas Totalis)	Purgator	The Wardens of Annihilation is a Loyalist Space Marine Chapter of the Adeptus Astartes. They possess a storied history characterized by resilience and tenacity. Their origins trace back to M31, during the Great Scouring when they were created from the gene-seed of Rogal Dorn's Imperial Fists. Create during the 3^rd Founding, the newly incepted Chapter was named the "Wardens of Vigilance" due to their dedication to maintaining Imperial vigilance over the Segmentum Solar. This name has changed, however, after the disaster at the Fall of Cadia and their Chapter's threatened extinction; the aftermath of which saw the chapter's remnants rename themselves the "Wardens of Annihilation".
Wardens of Orask	Imperium of Man (Fedelitas Totalis)	Sol Invitus	The Wardens of Orask are a 7^th Founding Successor Chapter of the honourable Ultramarines. The Wardens 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.
Warstalkers	Imperium of Man (Fedelitas Totalis)	Kastea	The Warstalkers (High Gothic: Bellum Venatorii) is a loyalist, Codex Astartes compliant Adeptus Astartes Chapter raised sometime during the Age of Apostasy (ca. M36). As the only known successors of the Royal Herculeans, they bear gene-stocks of the Ultramarines and their progenitor, Primarch Roboute Guilliman. From the advantage a fleet-based Chapter provides, the Warstalkers shouldered their duty to protect the Imperium's people in the spinward regions of Segmentum Pacificus from xenos, heretics, and traitor Astartes alike. They share the same goals as all Astartes chapters do and do their best to maintain friendly relations, especially with other Scion-Chapters of the War-Born such as the Swords of Guilliman. Though they are not as old as the Swords of Guilliman, they do their best to attain such glories and honors as the 2^nd Founding Chapter. The Warstalkers adhere to the tenets of the Codex with a religious ferver that is difficult to match, praising the God-Emperor of Mankind at every opportunity.
Winged Knights	Imperium of Man (Fedelitas Totalis)	(To be added)	The Winged Knights are a Loyalist, non-Codex-compliant Space Marine Chapter drawn from the lineage of the vaunted Blood Angels during the 4^th Founding. Though their lineage is clear, the exact Chapter from which they can claim to be the successors of is not. It has long been suspected that they are a Successor Chapter of the Angels Sanguine, the truth of that suspicion has yet to be confirmed. Though they were a Chapter of great honour for approximately two millennia, the stain of heresy has marred their reputation and they have never been able to escape the its legacy.
World Marauders	Renegade (Traitoris Perdita)	The Taker	The World Marauders are a Renegade Space Marine Chapter of an unknown origins formed during 23^rd Founding, also known as the 'Sentinel Founding'. Claiming to have lost faith in the Imperium, the World Marauders have survived through piracy, raiding ships, stations, outposts and worlds for supplies, weapons and even recruits. While not aligned with Chaos, they are neither allies of the Imperium of Man, though they have been known to work alongside the latter in certain circumstances.
