4th Founding (ca. Late-500s or Early-600's.M32)

This Founding occurred several standard decades after the climax of the catastrophic events of the War of the Beast - the massive Ork WAAAGH! Warlord known only as The Beast - which laid waste to much of the known galaxy and threatened to destroy Terra itself. Following the successful eradication of the massive greenskin invasion force and the defeat of its Warlord, the Lord Commander of the Imperium Maximus Thane, decreed that the Imperium would raise as many new Chapters as they had gene-seed in the great vaults of Terra to sustain. All Chapters of the Adeptus Astartes were ordered to release a portion of their Veterans to provide the initial basis for this Founding, the greatest since the First Founding. Gene-seed tithing would be doubled for the next standard century to replenish the vaults. When it was done, there would be hundreds of Chapters to ring the Imperium in adamantium and ceramite instead of dozens.

After enough gene-seed had been collected in the vaults on Terra, the High Lords of Terra authorised the 4th Founding of the Adeptus Astartes, sometime in the latter fifth century or early sixth century of M32, to help bring order to an Imperium rife with civil strife and insurrection, and to help restore Imperial law.

Blood Vultures
Blood Vultures SP
Blood Angels Regark Supposedly created during the 'Dark' Founding, this Chapter has garnered a dark reputation for being savage and unrelenting fighters. It is even believed by some that this powerful and robust Chapter is as mighty as their Progenitors.

Brotherhood of Man
SKULL LOGO SHIELD
Imperial Fists N/A (Fleet-Based) A rather insignificant Successor Chapter of the Imperial Fists, the Brotherhood of Man quickly found themselves in campaigns in the far reaches of the Eastern Fringe, operating with outdated equipment and little support.

Unknown (Chimeric Gene-Seed, primarily Imperial Fists gene-stock) N/A (Fleet-Based) The Abyss Gazers were founded to police the edges of the Eye of Terror and have only just managed to survive bad luck, mutation, and a section of the Chapter breaking away and turning to Chaos. After nearly twice being declared Excemmunicate Tratoris the chapter is now somewhat closely monitored by the Inquisition, much to their ire.
Ashen Drakes
Ashen Drakes SP
Salamanders (Allegedly) Inikar An alleged Salamanders' Successor Chapter, the Ashen Drakes are isolationist due to their being a part of the 'Cursed' Founding and are often shunned. They are one of the most human Chapters in existence, and often seek out the foes of Mankind to help protect Humanity.
Bullfrogs
Bullfrogs SP
Salamanders (Allegedly) Brazili Another alleged Salamanders' Successor Chapter, the Bullfrogs are afflicted by a unique mutation that causes their Betcher's Gland to overproduce toxins that secrete through their skin, creating a film of acidic mucous, and causing these Astates to reek of death and decay. They must wear specially modified power armour to counteract the acidic affects of this mutation.
Caustic Reach
Caustic Reach SP
Unknown (Presumably Raven Guard, unconfirmed) Tyran This mysterious Chapter operates along the extreme borders of the Eastern Fringe. The Caustic Reach are unusual, as they are somehow able to counteract the high potency of tyranid poisons. However, this has resulted in several of their specialty organs to overreact, producing excessive toxins to secrete uncontrollably via an Astartes' mouth.
Crusade Eternal
Pict-File Unavailable
Unknown N/A (Fleet-Based) A formerly loyalist Space Marine Chapter that were created to take the light of the Emperor to the enemies of Mankind. Unfortunately, due to their tainted gene-seed, and the corruption of their intended purpose, they have become a marauding warband that is a plague across the stars. (Excommunicate Traitoris)
Dread Echoes
Dread Eachoes SP
Raven Guard Chiroptera Created as they were during the Cursed Founding, like all of the Chapters from this Founding, the Dread Echoes suffered from the Mechanicus' attempts to improve their gene-seed stock. The Chapter's main gene-seed flaw is that it rends it's host completely blind, while increasing their hearing far beyond even the Astartes norm. The Chapter has adapted around these flaws, such as removing any image displays from their armour and equipment in favour of noise-based ones. The marines use echolocation to navigate, and have even developed a method of communication called Echo-Speak, based on noise pitches and differing sounds.
Eternal Legion
Eternal Legion SP
Unknown (Imperial Fists or Iron Hands, unconfirmed) Bethsaida Prime Supposedly created during the 'Dark' Founding, records indicate they use tactics similar to the Imperial Fists, but also exhibit a technological affinity as seen by the Iron Hands. As to which lineage the Eternal Legion truly belong to, none can say.
Imperial Hounds

Unknown Dongar This Chapter was created with experimental gene-seed of unknown origin that was heavily modified, and may have had more gene-seed organs implanted that were crafted by the Mechanicus' Magos. Their exact linage is unknown, though most sources point to Iron Hands progenitors. They are a fanatically devoted Chapter, their loyalty to the Imperium's people and the Adeptus Mechanicus is absolute.
Manticores
Manticores SP 2
Dark Angels N/A (Fleet-Based) The Manticores are a Renegade Chapter, originally part of the 'Cursed' 21st Founding and successors of the Dark Angels. Despite being deemed 'traitors', this is far from the truth. Near the ending of the M40, the Chapter was in pursuit of the infamous Fallen Angel, Cypher, which lead to the Manticores coming into conflict with the Inquisition. Rather than revealing the dark secret of the Fallen, the Manticores took the blame and were thus declared traitors. Now they roam the galaxy, chased by their former comrades, with only their fellow Unforgiven knowing the truth. (Excommunicate Traitoris)

Like their progenitors, the Raven Guard, these Scions of Corax have become worthy successors as masters in the arts of stealth and speed.
Obsidian Blades

Raven Guard N/A (Fleet-Based
Crastus Sigma (Formerly)
This Chapter's 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.
Phoenix Brethren
Phoenix Brethren SP
Raven Guard Zode I This Chapter hails from the surviving members of Flame Falcons, whose home world of Lethe was destroyed by the Grey Knights due to their unexpected mutation of their bodies spontaneously bursting into flame. Unharmed by this fire, they were deemed impure and set upon by the Ordo Malleus. Fleeing for their lives they took refuge on the dead world of Zode I. Like the proverbial mythical creature, the phoenix, this Chapter has risen from the ashes of their near destruction.
Quantum Marines
Quantum Marines SP
Iron Hands Enlightenment Alpha The Quantum Marines were one of the newly created Chapters that were recalled by the Imperium to be disbanded, due to severe genetic idiosyncrasies found within many 'Cursed' Founding Chapters. Like their progenitors, the Quantum Marines have developed a near insatiable fixation on cybernetic improvements and enhancement, which has led them to become more machine than flesh.
Silver Chimeras
Pict-File Unavailable
Unknown Unknown (Record Sealed by Inquisitorial Bull) Two millennia after their creation, a horrifying curse befell and overwhelmed this Chapter, threatening to destroy them. A genetic mutation caused the skin of their Astartes to seemingly transmogrify into molten metal, which eventually melted, causing weapons to meld with flesh, or killing the unfortunate battle-brother. They were wiped out by the Grey Knights. (Destroyed)
Sons Sanguine
Sons Sanguine SP
Blood Angels Sanggraal A Blood Angels' Successor Chatper that was established on Sanggraal to share with the Night Walkers the duty of supporting the Imperial Navy and Guard forces manning the Hadronian Wall located in the Aliris Sector against encroaching Forces of Chaos.

Gulf Hawks
Gulf Hawks SP
Ultramarines New Merica Hailing from the proud heritage of the Ultramarines, the Gulf Hawks were created to fulfill the needs of a specialist armoured/air-to-ground assault Space Marine Chapter, to counter the myriad threats of the Eastern Fringe that terrorize the Ultima Segmentum.
Imperial Sentinels

Dark Angels Purgatory (Destroyed) The Imperial Sentinels are known for having close ties with the Inquisition, more specifically the Ordo Hereticus. The Imperial Sentinels focus around defensive tactics, as they wish not to attack until a strong defence is built up.
Iron Sons
Iron Sons SP
Imperial Fists N/A (Fleet-Based) The Iron Sons are known for being a Codex Astartes-compliant Chapter in terms of combat doctrine and organisation, but are flexible enough to utilise ad-hoc formations or change tactics on the fly, when the situation dictates the need.
Knights of the Falcon
KoF Armorial
Dark Angels Faidor The Knights of the Falcon are a Successor Chapter of the vaunted Dark Angels. A very proud and conceited Chapter, they are nevertheless, faithful to the principles of chivalry and nobility. In battle they prefer close-combat, and due to the small size of their Chapter, they defeat their enemies through cunning tactics and the quality of their Knights. Settled on the Feudal World of Faidor, the Falcon Knights follow this planet's ancient feudal laws, and each knight of the Chapter is elevated to the title of aristocrat, as they clearly follow the Code of Chivalry, but have almost a complete disregard for the Codex Astartes.
Maverick Lords

White Scars Tempesuto The Maverick Lords are a Chapter known for their wily ways and reckless bravery on the field of war. Hailing from the churning seas and perilous mountains archipelagos of the Feudal World of Tempesuto, the Maverick Lords are often esoteric in their ways, mirroring the bottomless seas of their homeworld, fickle and inscrutable to outsiders.
Prophetic Forgiven
IconPropheticForgiven
Unknown (Successors of the formerly loyalist Prophets of Destiny) N/A (Fleet-Based) During the brutal civil war between the Loyalist Prophets of Redemption and their Renegade brothers, the newly renamed Prophetic Forgiven were sent on a 100 year Penance Crusade in order to atone for the crimes that their renegade brothers committed during their Chapter's internal strife. They are reputed as being a Chapter of harsh-minded Astartes who have adopted the same mentality as their Inquisitorial allies.
Swamp Dragons
Swamp Dragons SP 2
Ultramarines Ghagahtia Hailing from the feral world of Ghagahtia, which is covered in toxic swamps, this Chapter specialises in siegecraft, trench warfare and operating in contaminated or hazardous environments.

23rd 'Sentinel' Founding (ca. M37)

The 23rd Founding, known also as the 'Sentinel Founding', occurred during a period when the Imperium was hurting for some Marine firepower. They had lost a lot of Chapters in the time previous due to the Age of Apostasy, the Cursed 21st Founding and many other tragedies. The Imperium was being pressured by its enemies and they desperately needed a new generation of battle hungry Marines to replenish the deplete ranks of the Astartes and push back the rising tide. Thus the Sentinel Founding occurred. Sentinel Chapters tend to be restless, and possessed of a strong crusaders zeal. The Founding is filled with Crusade Chapters that plunged into the battlefields of the far future almost as soon as they were created, and never stopped fighting.

Laughing Skull
LS SP
White Scars Morozhko The Laughing Skulls are a Chapter born from shame, hate and vengeance, and are considered somewhat of an oddity to their peers. In combat, they are perceived as brutal savages, for their unforgiving and merciless approach to warfare. Outside combat, they are humorous and familial Astartes with questionable traditions.
Marines Ardent
Pict-File Unavailable
Iron Champions (Iron Hands Lineage) Jahan Created in the wake of the Third Navarine Crusade, the Marines Ardent specialises in rapid response, crushing threats to the region before they have a chance to grow. The native culture of their homeworld has deeply influenced the chapter although in terms of organisation they are mostly Codex-adherent.
Myrmidons
Pict-File Unavailable
Ultramarines Salona Though descended from the vaunted Ultramarines, this Chapter bears little in common with their legendary founders. Often seen as dangerous and unpredictable, the Myrmidons carry the savage culture of their homeworld with pride, forming bands of unruly warriors who flank tempered veterans.
Onyx Knights
Pict-File Unavailable
Unknown Trax The Onyx Knights are the lone Chapter based within the volatile Malitox Sector. Despite an impressive battle record and an altruistic nature, the reputation of the chapter varies between Imperial organisations. They are popular with the Imperial guard but unpopular with the Inquisition and the Adeptus Mechanicus.
Ordinators
Ordinators SP
Unknown (Classified by Ordo Malleus Directive) Azuran This Chapter is believed to have been founded on orders of the Ordo Malleus, in order to build upon the successful practice of daemonic possession therapy to create a specialized anti-Chaos Astartes Chapter in a besieged corner of the Imperium.
Phantoms Chapter
Pict-File Unavailable
Unknown (Rumoured to be Dark Angels, Raven Guard or White Scars) Fleet-Based (Currently) / Kambolas (Destroyed) The Phantoms Chapter are a Space Marine Chapter originally named the Nether Host, and as such are known to be battle-hardened warriors. The Phantoms were named in homage to the destruction of the Nether Marines, especially those murdered at the hands of the Scourge Knights. The Chapter's doctrine are largely based around close-combat, utilising a large number of Assault Marines, Assault Terminators and Dreadnaughts. The Nether Host were nearly destroyed shortly after their founding after the Chief Librarian Sa'vael Ra fell to the corruption of the Chaos God Tzeentch, resulting in a civil war within the chapter that split them into two separate forces - the loyalist Phantoms Chapter who were saved due to the timely aid of the Storm Crusaders, and the Chaos Warband dubbed "Scourge Knights", the latter of which are still lead by the surviving Sa'vael who seeks bitter vengeance against Chapter Master Malevos.
Space Naga
Space Naga SP
Ultramarines Indravari II This Chapter was created in order to fulfill the additional defence of the Eastern Fringe against the various threats that assail it.

Storm Zealot SP
Imperial Fists Jeras This Chapter was created in order to fulfill the additional defence of the Eastern Fringe against the various threats that assail it.

The Purifiers
The Purifiers Pauldron
Unknown (Imperial Fists - Suspected) Puris Alpha A highly conservative Space Marine Chapter of unknown origins, the Purifiers believe that every human in the Imperium has the taint of Chaos in them, they also have a tiny amount of redemption, a sliver of purity. The Purifiers seek to nurture this purity of others and destroy those they deem beyond redemption.

24rd Founding (ca. M39)

This Founding occurred in M39, when the Age of Waning began.

Notes
Blood Buzzards
Pict-File Unavailable
Unknown N/A (Fleet-Based) A relatively small Chapter rarely able to maintain the 1,000 battle brothers mandated by the Codex Astartes. This is due in part to the fact that they don't have a specific planet or route were they recruit new Battle brothers. Instead they have a system where other chapters will allow them to recruit from their home worlds often in exchange for artifacts of theirs that the Buzzards have recovered in their travels
Bone Reapers
Bone Reapers SP
Blood Angels N/A (Fleet-Based)
Mantho (Destroyed)
The Bone Reapers are a secretive and aloof Chapter, and due to this nature, their heroic acts and valorous deeds have been mostly unseen by the majority of the Imperium. They only recently discovered their lineage as Blood Angels Successors.
Scorched Spartoi
IMG 3710
Imperial Fists Inseriah With the collapse of the Jericho System, the Scorched Spartoi were initially created, along with several other Chapters, to help prepare to defend against the encroaching darkness that had already been well under way since M37. They are a Codex-compliant Chapter that does its best to conform the tenets of the Codex, but often stray from it to conduct their personalised tactics of blitz warfare.
Thunder Lances
Thunder Lances SP
White Scars Inankata A White Scars Successor Chapter, the Thunder Lances are masters of close quarters combat, lighting fast assaults, space battles, and bloody ambushes. They are well known throughout the Galactic East as savage and bloodthirsty warriors, but benevolent and quick to put civilian populations above all other tactical gains.

25th Founding (ca. M40)

The 25th Founding occurred at an auspicious time, as the Imperium had begun to face more dangers than ever before. Chaos had begun to gain momentum, the Tyranids were smashing into the galaxy, and aliens that would have never dared defy the Imperium before were now brazenly striking out against the Imperium. Having their work cut out for them, these young Chapters were most likely forced to be flexible and less set in their ways in regards to following the tenets of the Codex Astates, unlike their older, more rigorous brethren, who had long since put their trust in their time-tested methods of warfare and adherence to the Codex.

Crimson Dragoons
Dragoon Chapter Master
Imperial Fists Augustine A resolute and stalwart Chapter, the Crimson Dragoons are highly capable in all forms of ranged weaponry, which can only be matched by their faith in the God-Emperor. Shielded by faith and armed with zeal, they strike down anyone who would dare oppose the Holiness of the one true ruler of Mankind.
Desert Griffons
Desertgriifon
Ultramarines Yeth Originally, this Chapter was created to combat the ever-growing Chaos threat gathering near the Eye of Terror - specifically to combat the Chaos Warband known as the Berserkers of Arnkorn. However, in 878.M41, when Zoragon forces began to be amassed by T'eyucion the Older, they were reassigned near Zoragon-held space. They now fulfill the role previously filled by the now-extinct Bronze Vipers.
Dusk Ravens
Dusk Ravens Armorial
Raven Guard None (Currently) / Jorvac (Formerly) The Dusk Ravens were originally a loyalist Successor Chapter of Raven Guard lineage, created during the 25th Founding. They are best known for their skills in stealth and recon, as well as their specialty in Infantry-based aerial assaults and ambushes. Due to genetic deficiencies within their gene-seed, over several centuries, the Chapter's numbers rapidly dwindled, and they were considered a doomed Chapter. With the advent of the 13th Black Crusade and the subsequent Ultima Founding in 999.M41, the Chapter was saved by the influx of newly created Primaris Space Marines, though the older members of the Chapter remain divided.
Iron Bulls
Iron Bulls SP
Ultramarines Toranus III The Iron Bulls are a Loyalist Codex-compliant Successor Chapter of the Ultramarines. A relatively young chapter, they are notable in their determination to document in detail their history, an effort undertaken by their Master Librarian Ikos Yurin, who regards it as his duty to ensure the deeds and sacrifices of his brothers are not forgotten. They maintain their fortress-monastery on the world of Toranus III, a world they reshaped to their own purposes after overthrowing the planets former, corrupt Imperial ruler. They regard anyone who is not faithful to the Emperor as in violation of his will, and as such they maintain an unusually positive relationship with the Inquisition, willingly working with the Ordos Xenos and Hereticus during several campaigns without any hesitation.
March Wardens
March Wardens Icon
Imperial Fists N/A (Fleet-Based) This Chapter has had a mixed history of terrible downfalls and profound blessings. Their homeworld is Jogorran Prime and their current Chapter Master is Aximond the Unyielding.
Solar Wardens
Solar Wardens SP 4
Unknown (Successor of Hammer Guard) Mhuir The sole Successor Chapter of the Hammer Guard, the Solar Wardens follow a unique organization, casting aside the Codex Astartes. This divergence, combined with their Chapter cult and dubious gene-seed, had all created conflict with the Inquisition.
Tokaen Secrets Chapter
Tokaen Secrets SP
Dark Angels Tokea Unlike their Progenitors, the Dark Angels, and their fellow Unforgiven Chapters, Tokaen Secrets deviate from the set up from the elite formations of the 1st and 2nd Companies and do not follow the orthodoxy of the Codex Astartes.
Warriors of Fortuity
WoF SP 2
Unknown Felix Mundus This Chapter was created from unknown lineage, their sole purpose, - to add to the defences of the Ultima Segmentum. Most notably the area of many xenos incursions. Their homeworld of Felix Mundus is in the epicenter of various ork infested planets, the Tau empire, and the Alaitoc craftworld. This also places them near the Realm of Ultramar and Tyranid Hive Fleets' paths.
White Paladins
Pict-File Unavailable
Astral Knights Deregeus The White Paladins are a Successor Chapter of the Astral Knights and a one of two splinter groups of the disbanded Divine Paladins. Their gene-seed is cursed by the mysterious Dark Slumber that tempts them into sleep to be plagued by horrifying visions of countless possible futures. To counter these urges the White Paladin focus on discipline and purity above all else, avoiding glory and scrapping much of their history to avoid being remembered.

26th Founding (738.M41)

Before recent events, the 26th Founding of Space Marine Chapters was the most recent one, which occurred in 738.M41. There are only two known Chapters that were Founded at this time -- the Mentors and the Storm Giants.

Astral Crusaders
Pict-File Unavailable
Imperial Fists Barboda (The Grindstone) The Astral Crusaders are a loyalist Successor Chapter of the dour Imperial Fists. While their founding was no detriment to the Imperial Fists or any other chapter, it still remains somewhat controversial. Founded as an experimental idea for rapid response there are those detractors who consider this particular Founding as not necessary, though alternative reasons are few and far in between. Originally this led to a level of distrust from other Astartes chapters, concerned that the Astral Crusaders were puppets of some political shadow who wormed their way into obtaining a chapter to do their bidding.
Burning Lords
Burning Lords SP
Salamanders (Suspected) N/A (Fleet-Based) A suspected Salamanders Successor Chapter, the Burning Lords are a fleet-based Crusading Chapter that patrols the sectors of the Segmentum Pacificus, including the Sertarian Sector.
Dream Stalkers
Dream Stalkers SP
Doom Eagles Tindalos The Dream Stalkers are a loyalist Successor Chapter of the Doom Eagles, with close ties to the Adeptus Arbites. While they do share their progenitor's morbid nature, the Dream Stalker Astartes do not accept their eventual death with grim fatalism. Instead, they strive to become nightmares incarnate that relentlessly haunt the existence of those who would dare oppose the Imperium. The Astartes of the Chapter do not adhere closely to the Codex Astartes, however, they do respect and honour the Codex as the work of their Primarch.
Feudal Vindicators

Salamanders (Allegedly) Apello A formerly loyalist Space Marine Chapter that was supposedly created from Salamanders' lineage.

Sinopia Mongoose SP
Unknown Barstar A young Chapter created from unknown lineage, considers its mysterious origins to be a blessing of sorts. They are unburdened by the lingering scars of the Horus Heresy, the implementation of the Codex Astartes and the break-up of the Legiones Astartes. They don't concern themselves with the identity of their Primarch or their Progenitors, instead dedicating themselves to their home system and the Imperium at large.
Sons of Iron
SoI SP
Iron Hands Suami A cold and unforgiving Iron Hands Successor Chapter, the Sons of Iron hail from the perilous world of Suami. They are unique in their beliefs amongst the Chapters of Ferrus Manus, as they follow the tenets of the Parchment of Neimerel - a controversial document supposedly written by the hand of the Gorgon expressing his wish to strip his hands that were encased in the strange silver substance, and to help his sons resist the urge to replace the organic with the bionic. Though the Sons of Iron share the same compulsion to use bionic replacements, they try to resist it.
Steel Wardens

Unknown N/A (Fleet-Based)
Thantia (Destroyed)
Created from unknown lineage, the Steel Wardens were initially created to act as a first line of defence against marauding Chaos bandits.

27th Founding ('Primaris Founding', ca. 999.M41)

As the end of M41 draws to a close, Abaddon the Despoiler, Warmaster of Chaos, led his 13th Black Crusade, the largest Chaos incursion from the Eye of Terror since the Horus Heresy. They immediately attacked the fortress world of Cadia, and despite the Imperial defenders valiant defence and after much sacrifice, Cadia has fallen to the Archenemy. Fortunately, a handful of survivors escaped the destruction of Cadia with the help of the Eldar faction known as the Ynnari through the Webway and fled towards the Realm of Ultramar - to resurrect the Ultramarines Primarch Roboute Guilliman from his deathless slumber!

After successfully resurrecting the Avenging Son, Guilliman immediately set out on his Terran Crusade, to seek and audience with his father, the Emperor of Mankind. After he succeeded in this endevour, he immediately assumed command of the High Lords of Terra, and acting as the Lord Commander of the Imperium, assumed command of all of the Imperium's military forces. As the terrible encroaching darkness descended upon the galaxy, the Primarch enacted his ultimate contingency plan, which had long been put into motion by Guilliman 100 standard centuries past. Utilising the sagacity of the Adeptus Mechanicus, combined with the long forgotten technology from the Dark Age of Technology, a new legion of transhuman warriors had been created beneath the surface of Mars - the Primaris Space Marines.

These gene-crafted warriors are superior to an average Astartes warrior - larger, tougher and arrayed with the finest arms and equipment forged by the Adeptus Mechanicus to date. By order of Roboute Guilliman, a new Founding has taken place, and many newly Founded Chapters were comprised entirely of Primaris Space Marines. Launching his Indomitus Crusade, Guilliman gifted thousands of Primaris Space Marines to help alleviate the losses suffered by several existing Chapters.

Arbiter Knights
Pouldring
Dark Angels Iuris The Arbiter Knights are a newly founded, loyalist Chapter of Primaris Space Marines. Created from the lineage of the venerable Dark Angels, the Arbiter Knights are a chapter whose sole purpose is to purge early signs of Chaos and xenos corruption. Many other factions, not just the parts of the Imperium, have come to see the actions of the Arbiter Knights as preemptive and of an agenda, which is not helped by the rumored secretive links to the inquisition. Although claiming loyalty to the Emperor of Mankind, their ability to make swift judgment and quick action against their fellow man has made many question that loyalty. Others, however, see it as a necessity to keep the spread of chaos corruption at bay.
Charnel Warhawks
Charnel Warhawks SP 2
Dark Hunters Graveshead (Destroyed) The Charnel Warhawks are a newly founded fleet-based loyalist chapter of Primaris Space Marines. Their specialty is rooting out cults, be them Chaos, Genestealer or some other variant. This has led to close ties with the Ordo Hereticus, who value their ability to protect mankind from itself. Given the urban locale of many cults, the Charnel Warhawks have become brutally efficient at urban warfare.
Corpse Wolves

Space Wolves Ragnarok The Corpse Wolves are a newly founded Successor Chapter created from the proud lineage of the feral Space Wolves. Comprised entirely of Primaris Space Marines, the Corpse Wolves were tasked to help stem the tide of the influx of the Forces of Chaos, in the wake of Abaddon the Despoiler's 13th Black Crusade.

Space Wolves N/A (Fleet-Based) The Crimson Prowlers are a loyalist Successor Chapter of Primaris Space Marines, created from the lineage of the mighty and powerful Space Wolves. They were created as one of the first of many Successors, a whole line of descendant Fenrisian Chapters - the 'Sons of Russ' - capable of carving out a star empire the size of Ultramar. This was the vision: to be powerful enough to encircle the Eye of Terror completely, to prevent the Traitor Legions from daring to leave it ever again. The Crimson Prowlers, along with several other Primaris Successor Chapters, were created to help protect the Imperial sectors surrounding the Eye, and supporting Imperial worlds and the Inquisition as needed.
Dawn's Wolves
Dawn&#039;s Wolves SP
Space Wolves N/A (Fleet-Based) The Dawn's Wolves are a loyalist Successor Chapter of Primaris Space Marines, created from the feral lineage of the mighty Space Wolves. They only came together as a Chapter, following the end of the Indomitus Crusade, from the ranks of the Unnumbered Sons. Since that time, the errant Chapter has made is best to defend the borders of the Imperium and bring the wrath of Leman Russ upon the enemies of Mankind. This origin explains why they are far less independent and more prone to cooperation with other Space Marines. This Chapter is also known to make up part of the 'Sons of Russ', an unofficial collective comprised of several Space Wolves Successor Chapters.
Dusk Howlers
Dusk Howlers SP 1
Space Wolves Hrímgard The Dusk Howlers, known as the Vlka Hrímherjar (translated as the 'Wolves of Hrímgard'), are a loyalist Successor Chapter created from proud lineage of the feral Primarch Leman Russ. Comprised entirely of Primaris Space Marines, the Dusk Howlers were created as a shock-assault force, to take back those worlds lost to the Traitor Legions in the wake of the formation of the galaxy-wide tear in reality known as the Great Rift. This Chapter is also known to make up part of the 'Sons of Russ', an unofficial collective comprised of several Space Wolves Successor Chapters.
Lycan Guard
Lycan Guard SP
Space Wolves Helgas (Ramillies-class Starfort) The Lycan Guard are a loyalist Successor Chapter of Primaris Space Marines, created from the feral lineage of the mighty Space Wolves. The Lycan Guard chapter was created after the end of the Indomitus Crusade from the ranks of the Unnumbered Sons. The Lycan Guard settled upon the battered and abandoned Ramilies-class Starfort Helgas, orbiting the feral world of Ayal, in the northeast part of the Ultima Segmentum.
Macragge's Guardians

Ultramarines Unknown The Macragge's Guardians are a loyalist Successor Chapter created from the proud lineage of the vaunted Ultramarines, and are comprised entirely of Primaris Space Marines.

Night Griffons
Night Griffons SP
Salamanders Alteros Prime The Night Griffons are a loyalist Codex-deviant chapter founded in the wake of the 13th Black Crusade as a part of the Ultima Founding to help bolster the front lines. Assigned the planet of Alteros Prime, in the Alteros system of the Segmentum Obscurus, the Night Griffons were tasked with being amongst the first Primaris Space Marine chapters to maintain a permanent presence within the Segmentum Obscurus to combat the Forces of Chaos. The Night Griffons Astartes are exceptionally resilient and are resolute to a fault but this has already cost the chapter dearly with the chapter currently maintaining a below nominal force of space marines.

Unknown Foundings

The establishment of new Foundings has been occurring for more than ten millennia, since the First Founding of the 20 original Space Marine Legions of the Legiones Astartes. There have been 25 subsequent Foundings of new Chapters of the Adeptus Astartes, with the most recent, the 27th Founding, occurring in the year 999.M41. But in all that time, records become lost or history becomes convoluted, an inevitably, the details of some Foundings have become obscured by the long march of time. This results in many Chapters being listed as 'Unknown', as there are no accurate historical records indicating when some Chapters were created or from whose lineage they sprang.

Black Raptors
Black Raptors SP
Imperial Fists Espada-Delta (Current)
Fleet-Based (Formerly)
This Chapter was created from the stoic Imperial Fists during an unnamed Founding in M33. They were created as part of a prognostication to liberate the Death World of Espada-Delta against Tau Forces.

Charnel Brethren
Charnel Brethren SP
Flesh Tearers (Blood Angels' Lineage) Sanguinius' Light This brutal and blood-handed Chapter was created from the bellicose Flesh Tearers Chapter during an Unknown Founding. Ancient Imperial records indicate that they might have been a part of the 3rd Founding that took place in 001.M32. This Chapter is slowly dying due to the ravages of the Black Rage, which has reduced their numbers to only 300 Astartes.
Chronal Guardians
Chronal Guardians SP 2
Unknown Uknown A strange and technologically superior Chapter, the Chronal Guardians' origins have been sealed away under the sigil of the Ordo Chronos. Therefore, it is not known if they were created in the past or the far-flung future. It is believed that they fight against temporal threats to humanity. Their weapons are never above those from the current time line they are in, apart from a few exceptions.
Corvus Legion
Corvus Legion SP
Raven Guard Coraxium A cunning and strategically brilliant Chapter, the Corvus Legion were created from Raven Guard lineage during an Unknown Founding, but some believe that they might have been created as early as M32. Like their Progenitors, they are both superlative guerilla fighters and patient hunters, which they utilise for infiltration missions deep behind enemy lines.
Crimson Scorpions
Crimson Scorpions SP
Royal Scorpions (Blood Angels' Lineage) Calet This Chapter was created during an Unknown Founding from the lineage of the brutal and bloody-handed Royal Scorpions Chapter, although they are not acknowledged by their Progenitors. This is mainly due to the Chapter's unique belief that the machine is stronger than the flesh, and often replace much of their organic bodies with bionics. They believe this has help them stem the tide of their Chapter's twin genetic-curses inherited from their Blood Angels forefathers.
Crimson Thunder
Crimson Thunder SP

Death Ravens
Death Ravens SP
Unknown Unknown The Death Ravens are an infamous and blood-handed Chapter created during an Unknown Founding and from uncertain lineage. Although some Imperial scholars suspect they might have been created as far back as the 3rd Founding in M32. Though they are extremely loyal to the Emperor, their conduct, brutality and genetic flaws has often led to investigations by the Inquisition.
Death Scythes
Death Scythes SP
Unknown Sacrata Regionis An obscure and little known Chapter, the Death Scythes were created during an Unknown Founding sometime during M36. Little trace of their Founding remains, but some evidence points that they are perhaps of Iron Hands lineage. They prefer a brutal form of mechanised combat.

Draconite Lords
Draconite Lords SP
Unknown N/A (Fleet-Based) This Chapter was founded in early M38 as a Successor Chapter of the Rogue Angels Chapter, but due to an Administratum error, the origins of their gene-seed is unknown as it can only be traced back two Foundings before gaps in the records appear. They were subsequently lost in a Warp Storm in late M39.
Drake Bloods
Drake Bloods SP
Salamanders (Unconfirmed) Pachiea The Drake Bloods are a newly created, Codex-compliant Chapter. It is said the High Lords of Terra created the chapter to aid the embattled worlds after the destruction of no less than three Space Marine chapters following the disastrous Abruptia Crusade. Rumours abound that the Drake Bloods were created from the gene-seed of the Salamanders Chapter and that they were founded with the aid of their kin. This Chapter is known for their deep respect of the Imperial Guard and all those who fight for the Imperium.
Dust Lords
Dust Lords SP
Raven Guard Unknown (Destroyed) The Dust Lords are a Space Marine Chapter created during an Unknown Founding created from Raven Guard lineage. They are simultaneously a renegade chapter of Space Marines and Chaos Space Marine warband. During their time serving the Emperor they were known, much like their parent chapter, for their ambush tactics and proficiency in the use of Jump Packs. Now they have been declared Excommunicate Traitoris by order of the Ordo Hereticus for reasons the Inquisition are not willing to openly disclose. (Excommunicate Traitoris)
Emperor's Basilisks
EB SP
Unknown Zalimos (Destroyed) A formerly loyalist Chapter of Unknown Founding and lineage, though some believe they were created during the 13th 'Dark' Founding. While at first the chapter had a rather heroic history, their fate was ultimately sealed within their own flesh and blood, as the chapter was known to be prone to psychic mutations within their ranks. The only known survivors of the now purged chapter are Amanu Ensis and Captain Levigan of the Second Company alongside less than forty of battle-brothers under Levigan's command.

Golden Lions
Golden Lions SP
Imperial Fists Terralba Majoris The Golden Lions are a Loyalist Codex-divergent Chapter from an Unknown Founding that have lost almost all of their past history, with only around 500 years worth of records from the point of the Konor Campaign. What was once a proud Codex Chapter has now allowed the two philosophical viewpoints of their Homeworld, Terralba Majoris, to almost split the Chapter.
Grave Bearers
Grave Bearer imagery
Black Templars Gryphonne IV The Grave Bearers are a Successor Chapter of the zealous Black Templars. They derive their name from the ritual practice of engraving the names of their fallen battle-brothers on the inside of their armor. The armor then becomes the grave of their fallen brother. The armour is eventually passed on to the next battle-brother after the initial bearer's death, thus, the new recipient bears the grave of the last owner, which will inevitably he his own. For this reason, the Grave Bearers will go to great lengths to recover a fallen brother's armor.
Gulf Knights
