Disciples of Caliban - Chapter History: A great deal of mystery surrounds the foundation of any Chapter created using the gene-seed of the Dark Angels, for while their genetic line is held to be pure and free from mutation, it is very rarely used to sire new successors.The creation of the Disciples of Caliban was unusual, in that then-Chapter Master Anaziel of the Dark Angels specifically requested the creation of a new Space Marine Chapter from Dark Angels gene-seed of the High Lords of Terra sometime during the 37th Millennium.Such a request by one Chapter for the creation of another was, and remains, unheard of in the Imperium of Man, and much debate followed among the members of the Senatorum Imperialis on Terra before Anaziel's request was granted. The stored Dark Angels gene-seed used was examined using standards even more strict than was normal when the Adeptus Mechanicus moved to create a new Chapter of Astartes because of the Inquisition's continuous suspicions concerning the Dark Angels and the other Unforgiven Chapters' motives. As a result, even today, the gene-seed of the Disciples of Caliban is constantly being monitored for corruption by the Genetors of the Mechanicus.It appears there was a specific mission in mind for the new Chapter, though as ever, the Unforgiven never committed any details to the annals of the Imperium's history. The fact that the Dark Angels could bring such influence to bear on the Senatorum Imperialis as to bring about the creation of a new Chapter has not gone unnoticed, and is cause for great concern in some quarters.Despite the shrouded circumstances of their Chapter's Founding, the battle-brothers of the Disciples of Caliban are generally held to be noble and virtuous. As they should be, for they are subject to a regime of genetic assessment far more rigorous than many other Chapters maintain. What happens should a battle-brother fall short of the incredibly high genetic purity threshold he is required to meet is not known.The Disciples of Caliban are a fleet-based Chapter, and an exceptionally active one at that. In the comparatively short term of its existence, the Chapter's forces have been witnessed fighting in numerous war zones the length and breadth of the Imperium.Many of the wars the Chapter has become involved in appear to have been instigated by the Fallen Angel known as Cypher, though the causes of some are simply inexplicable. It is known that Cypher is a master at fomenting anarchy and discord wherever he passes and able to inspire apocalyptic planetary insurrections with but a single cryptic transmission.In turn, the Disciples of Caliban have become adept in tracking down the activities of the Fallen, especially those of Cypher, and of acting upon the slightest scrap of evidence. How many Fallen the Disciples of Caliban have captured to be dragged back to the excoriation chambers of the Dark Angels is not known, but surely the number must rival those of other Dark Angels successors much older than themselves. It is even said that the Disciples of Caliban have on several occasions engaged Cypher directly, their enemy eluding them by the smallest of margins.Despite the Inquisition's suspicions, the Disciples of Caliban never turn from their duties to the Imperium, though like all the Unforgiven, they can be sidetracked in their hunt for the Fallen, particularly for Cypher.The Chapter is noted for carrying relics into battle. The most important of these relics is the Lionus Censum, a scroll which has the names and deeds of the Chapter's most famous brethren recorded upon it.
