13th Black Crusade (Original) - Dark Angels: Caliban was the site of many bitter battles throughout the war, and the Dark Angels Chapter was forced to defend the ruins of their former homeworld against the blasphemous hordes of the Abaddon the Despoiler, who were intent upon desecrating the holy ground. But, despite the vindictive campaign of lies and profanity conducted by the heretic known to his followers as the "Voice of the Emperor," which were seemingly designed to draw the Dark Angels into pointless battles away from the main fronts, they did in fact prove invaluable in many conflicts across the region - despite the generally held view that the Dark Angels and their Successors (collectively known as the Unforgiven) fought exclusively and selfishly for the ruins of Caliban while Cadia burned.At the close of the war, Caliban was firmly in the hands of the Dark Angels, its secrets safe for the time being. The Dark Angels had not only held Caliban against continuous attack, but were able to counter the activities of a number of the Fallen Angels, better known as the Fallen -- the rogue brethren who the Chapter and its UnforgivenSuccessors have relentlessly hunted to the exclusion of all other considerations for ten millennia. The so-called "Voice of the Emperor" put much effort into sewing disunity amongst the defenders of the Cadian Gate, seeding doubt as to just what the Chapter was hiding amongst the frozen ruins of its homeworld. Rumours abound that the Dark Angels have since captured the "Voice of the Emperor" himself, only for this mysterious Heretic to escape his prison en route to the Tower of Angels. Other rumours suggests that Lord Castellan Ursarkar Creed now harbours a deep resentment towards the Chapter, whose presence, he feels, might have proved critical in the defence of Cadia in the most desperate phases of the war, were the Chapter not focusing its efforts upon Caliban. Having suffered the presence of the servants of the Ruinous Powers, the holy places of the Caliban System have now been reconsecrated by the most senior Interrogator-Chaplainsofthe Chapter, and it is clear that, whatever the result of the larger war, no devotee of Chaos shall ever again approach within a light year of the Caliban System again.The mysterious leader of the Fallen, Cypher has been hunted by the Dark Angels and their Successor Chapters for ten thousand years. Though it is not known whether Cypher was encountered directly during the war, unconfirmed reports suggest the Chapter's Interrogator-Chaplains captured as many as 8 Fallen during the battles around the Caliban System, more than have been captured in such a short period in many thousands of standard years. Further reports link Cypher to the mysterious "Voice of the Emperor" on the world of Lelithar, who, it is rumoured, was captured by the Dark Angels during the fighting, but whose cell was found empty upon the prison ship's return to the Tower of Angels aboard the Dark Angels vast, mobile Fortress-Monastery known as The Rock.Azrael, the Supreme Grand Master of the Dark Angels, was a notable absentee at the council of Chapter Masters that elected Logan Grimnar their head at the start of the 13th Black Crusade. Azrael led the Dark Angels, and the so-called Unforgiven Chapters, according to his own, inscrutable strategy. The only time he is known to have stood beside other Imperial forces was when he led a company of Dark Angels upon Xersia, where he joined with Lord Castellan Creed and his 8th Cadian Regiment to repel a force of Black Legionaries from the world's High Basilica, though Abaddon succeeded in his sacrilegious mission to desecrate the high altar as part of some dedication to the Ruinous Powers that would guarantee the success of the 13th Black Crusade. Azrael was instrumental in repelling the invaders, for a time at least.
