Unforgiven - Notable Unforgiven Chapters: When the Space Marine Legions split into Chapters after the Horus Heresy as recounted above, the Dark Angels Legion sired at least three new Chapters, but more are rumoured to exist.Although frequently passed over in subsequent Space Marine Foundings, the Dark Angels have periodically been requested to give gene-seed to found new Chapters of the Adeptus Astartes.The Dark Angels' Successor Chapters collectively call themselves the Unforgiven, for their own Inner Circles are fully aware of the ancient Ist Legion's checkered history and they, too, seek to absolve themselves of their ancient failure.As noted, each of the Unforgiven Chapters follows the Dark Angels tactical organisation almost exactly, and maintain formations identical to the Deathwing and the Ravenwing, though they are not always named as such. The Unforgiven coordinate their actions, and it is not unknown for the Supreme Grand Masters of all the Chapters to gather for regular summit meetings on The Rock, often to discuss their progress in the hunt for the Fallen.Although duty-bound to run their Chapters autonomously, it is strongly suspected by some within the Imperium, especially the Inquisition, that the Dark Angels' Successor Chapters show too much deference to the Supreme Grand Master of their originating Chapter.It is, at least partially, this rumour of forbidden "Legion-building" that often persuades the High Lords of Terra to overlook the Dark Angels gene-seed when seeking to create new Foundings.Dark Angels - The Dark Angels were the inheritors of the Ist Legion's name, iconography, mantle and traditions. As the custodians of The Rock, the last remnant of lost Caliban in the universe, the Dark Angels are automatically looked upon as the leaders of the Unforgiven. The wishes of the Supreme Grand Master of the Dark Angels can sometimes be decisive in determining the course of action undertaken by the other Unforgiven, especially in the hunt for the Fallen Angels.Angels of Absolution - The Angels of Absolution have fought throughout the known galaxy, most often alongside the Dark Angels Chapter, in joint operations such as the Crusade against the Ork empire of Charadon, the Battle at Archangel VII or the bloody suppression of the Rasputin Uprisings. In doctrine and temperament, the Angels of Absolution are very close to the Dark Angels. The two Chapters' teachings are largely consistent -- the only divergence lies in the emphasis placed on the Chapter's guilt concerning the Fallen. Though it is a subtle distinction, the Angels of Absolution consider their own sins expunged by their forefathers' actions in the Fall of Caliban. Though the Angels of Absolution fear no damnation from the consequences of that Fall, they still consider themselves responsible for meting out the punishment upon the Traitors. Currently, the Angels of Absolution are wholly committed to stopping the 13th Black Crusade, and all ten companies are deployed in some fashion on those battlefields around the Eye of Terror as they seek to contain the aftereffects of Abaddon the Despoiler's latest assault upon the realm of Mankind. The Angels of Absolution have reported back to The Rock the confirmed presence of several members of the Fallen amongst the forces of Chaos that emerged from the Eye with the Despoiler.Angels of Defiance - The Angels of Defiance is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines and raised during the Ultima Founding of ca. 999.M41.Angels of Redemption - Nothing can dissuade the Angels of Redemption from their mission to hunt down the Fallen, and it has been noted that the Chapter has, on occasion, withdrawn from a campaign in order to pursue their own undisclosed ends. It was at the height of the Defence of Gaitlinghive that the Angels of Redemption redeployed at the moment of the Orks' final assault, leaving seven brigades of Gaitlinghive militia alone to face an Orkish horde three million Greenskins strong. The Angels of Redemption were never called to account for this act, as there were no survivors to press any formal inquiry. The Angels themselves embarked upon a hunt that led them to capture a Fallen Dark Angel -- a victory, to them, worth the lives of the Gaitlinghive militia, and the population of the hive city they fought to protect. Perhaps due to this incident, and other similar events, Imperial forces have actually declined the aid of the Angels of Redemption. The consequences of their reputation have yet to emerge, but could range from Inquisitorial censure to outright excommunication, depending upon the Chapter's actions in the coming years.Angels of Vengeance - The deeds of the Angels of Vengeance are even less well-known than those of the other Unforgiven Chapters, for they shun fame and laurels, instead concentrating on their duties to the exclusion of all else. They are a grim and dour organisation, with all of their companies wearing power armour of jet black. This is a tribute to the panopoly worn by the original Dark Angels Legion, when they first set out from Terra on the Great Crusade in ca. 800.M30.Angels of Vigilance (Suspected) - The Angels of Vigilance are a monastic Chapter of Space Marines whose mysterious origins may go back to the bygone days of the Second Founding during the 31st Millennium. It is unknown from which Space Marine Legion their gene-seed was drawn, though the Angels of Vigilance themselves believe they are descended from the Dark Angels. They have stood silent vigil over the Eye of Terror as sentinels against the encroaching forces of Chaos for nearly ten millennia if the rumours about their origins are true.Blades of Vengeance -  The Blades of Vengeance is an Unforgiven Chapter comprised entirely of Primaris Space Marines and raised during the Ultima Founding of ca. 999.M41. It participated in the Indomitus Crusade and the War of Beasts.Angels of Wrath - Though its Founding is unknown, the Angels of Wrath may have been created during the 10th Founding in the mid-35th Millennium, as by the 36th Millennium, they were still considered a young Chapter. During the Age of Apostasy, the seeds of the Angels of Wrath's destruction were sown due to the machinations of the insane High Lord Goge Vandire, during the Age of Apostasy. It is unknown if this Chapter still exists in the 41st Millennium.Bringers of Judgement - The Bringers of Judgment are possessed of a fanatical zeal that gives the other Unforgiven Chapters pause. When they encounter rebellion, they deem the entire world guilty. In their view, weakness in even one citizen indicates weakness in the entire population, and the punishment for weakness is death. The many atrocities they have committed have drawn the ire of the Inquisition, though this has not dissuaded them from their genocidal course of conduct.Consecrators - The Consecrators Chapter is a mystery. No record of their existence is to be found prior to the third century of the 40th Millennium. The Chapter's first appearance is in the works of the field notary Corwen Quilp, in his account of the Second Kuppukin Schism. At the height of this terrible war, Loyalist forces were surrounded by the foe when the entire Consecrators Chapter deployed in their support. Though never answering friendly transmissions, the Consecrators launched an immediate attack upon the enemy and, within six hours, the Consecrators had wiped out the schismatists' entire high command structure, breaking the back of the rebellion, and essentially winning the war. Their task complete, the Chapter withdrew, not to be seen for another three decades, when its 4th Company fought alongside the Dark Angels at the Arrulas Intervention. Though his descriptions are vague, Quilp is very specific about one element of the Consecrators' appearance -- he noted that the brethren of this Chapter bore all manner of sacred relics, and used the most ancient patterns of Imperial armour, weaponry and vehicles. It was as if, Quilp commented, the Consecrators had inherited the most revered arms of the ancient Ist Legion, preserving them lovingly, and bearing them down the ages against the foes of the Lion and the Emperor.Cowled Wardens - The Cowled Wardens' base of operations lies within the Sirikoid Belt, a part of the region known as the Tears of Piruz. Rather than a single fortress-monastery, the Chapter operates out of several hollowed-out asteroids. Nominally tasked with the purging of the savage Jehangir xenos that terrorise the region, the Chapter's secret purpose is the investigation of what the Unforgiven believe to be a large network of the Fallen in the area. Those Fallen Angels that are captured by the Cowled Wardens are consigned as prisoners to icy catacombs they have carved within a nameless asteroid of the Sirikoid Belt.Disciples of Caliban - The Founding of the Disciples of Caliban is shrouded in controversy. It is believed that Dark Angels Supreme Grand Master Anaziel made a strong request of the High Lords of Terra for a Chapter to be raised late in the 37th Millennium. Much debate followed, for it is highly unusual for a Chapter Master to make such a request, though it was eventually granted and the Disciples of Caliban were founded. Some have suggested that Anaziel must have had some sort of leverage over at least one High Lord to achieve such a thing. The Disciples' Founding gene-seed was of the highest pedigree held by the Dark Angels at the time, and scrutinised to a standard far beyond even that required by the Adeptus Terra. To this day, the purity of the Chapter's gene-seed is constantly monitored for the slightest sign of corruption or genetic degradation, and it has the most exacting standards of recruitment of any of the Unforgiven Chapters. There have been whispers that Anaziel had the Disciples of Caliban created to fulfill a specific purpose, often rumoured amongst the other Unforgiven to be for the single-minded pursuit and capture of the Renegade known as Cypher. The Disciples of Caliban are a fleet-based Chapter, which has greatly aided the rapidity with which they can traverse the Imperium. Their flagship houses great reliquaries celebrating the success of their forebears. Each company has several Relic Bearers who carry the Chapter's most sacred artefacts to war to inspire the brethren. The most precious of these relics is the Lionus Censum, an immense scroll that details the names and deeds of the Chapter's most decorated battle-brothers.Guardians of the Covenant - It is not known from what Founding the Guardians of the Covenant came, only that they too are part of the Unforgiven. Their adopted homeworld, Mortikah VII, lies near the western rim of the Imperium, and their mountain-top fortress-monastery takes the form of a mighty Imperial cathedral, its great spire piercing the clouds. The Guardians of the Covenant have fought most of their battles within Segmentum Pacificus. They are known to have spearheaded a number of Imperial Crusades into the Halo Stars and the Veiled Region. The Guardians of the Covenant gained special honours for their deeds during the Lelith Incursion, when they saved an entire Sub-sector from a particularly appalling brand of xenos subjugation. The Chapter is known for its exceptionally monastic character. True warrior-monks of the Emperor, they are assiduous in studying the teachings of the Emperor and of their primarch. Their banners, armour and the flanks of their vehicles are covered in spidery, handwritten and illuminated High Gothic text extracted from the pages of the Codex Astartes, the Requiem Angelis and many other tomes held sacred by the Adeptus Astartes.Knights of Abhorrence - In the first eight standard centuries after their Founding, the Knights of Abhorrence fought solely in the Ghoul Stars, blooding their swords with the viscera of some of the most dangerous xenos the Imperium has ever encountered. In the years since, they have patrolled the outer reaches of the Imperium, slaughtering alien horrors whilst acquiring information on the Fallen. It was they who first alerted Supreme Grand Master Azrael to the events in the Warp rift near the Somnium Stars after the escape of Luther from The Rock. Rumours grow of a dire threat mounting. Reports from this isolated region of space suggest that the Fallen are amassing there in unprecedented numbers. This mustering is a grave threat that the Chapters of the Unforgiven will not ignore. The Chapter also maintains the secret 57th Protocol with the Deathwatch, which sends its battle-brothers to serve with the Chamber Militant of the Alien Hunters.Knights of the Crimson Order - Almost nothing is known about the Knights of the Crimson Order in Imperial records save that they exist and that they too are numbered amongst the ranks of the Unforgiven.Lions Sable (Destroyed) - The ill-fated Lions Sable Chapter was the last of the Second Founding Successor Chapters of the Dark Angels. During the unspoken period of history known as the Forgotten Wars (580.M31-632.M32), the Lions Sable were completely annihilated during a disastrous campaign into the Eye of Terror whilst in pursuit of the notorious Fallen known as Cypher. Their subsequent fate and entire Chapter history was deliberately destroyed by the Dark Angels. Ironically, by the 33rd Millennium, when the great and holy document known as the Apocrypha of Davio was written in an attempt to list all of the known Second Founding Chapters, the name Lions Sable had already been lost.Penitent Blades - The Penitent Blades hail from a world with a landmass made up of thousands of small landmasses suspended kilometres in the air above acidic oceans. How this phenomenon occurs is a mystery, but it has ensured the Penitent Blades are aerial combat experts. The Penitent Blades' 2nd Company has four oversized squads providing gunship pilots, rather than the two in most other Unforgiven Chapters.Persecutors of Darkness - Almost nothing is known about the Persecutors of Darkness in Imperial records save that they exist and that they too are numbered amongst the Unforgiven.Prime Absolvers - Chapter Master Dagiel Harn of the Prime Absolvers, a Chapter comprised entirely of Primaris Marines raised during the Ultima Founding, first learned of the existence of the Fallen from Supreme Grand Master Azrael himself. A headstrong warrior, he saw no reason for his Chapter brethren to feel the responsibility borne by many of the other Unforgiven successors. To Dagiel Harn the Fallen are no different than other Traitors. Though he established an Inner Circle for his Chapter and specialised companies (reminiscent of the Dark Angels' Deathwing and Ravenwing), he sees his Chapter's mission as hunting all the Emperor's foes equally.Star Phantoms (Suspected) - The Star Phantoms is a Chapter of the 23rd Founding created in the early 38th Millennium from an unknown genetic origin. It took part in the final days of the Badab War and the final assault upon the Astral Claws' homeworld of Badab Primaris, helping bring the war to a successful conclusion. Some Imperial scholars of the Adeptus Astartes suspect that the Star Phantoms were created from the gene-seed of the Dark Angels, which, if true, would be unusual, not only because the Astartes of the Chapter do not suffer from any known mutations, but because the Dark Angels' gene stock is rarely utilised by the Mechanicus for new Foundings. The Dark Angels themselves deny the lineage, while the Star Phantoms regard any such enquiries as impertinent.The Unnamed - The Unnamed are a successor of the Dark Angels created solely from Primaris Space Marines during the Ultima Founding of ca. 999.M41.
