Luther - Luther: Luther, also known as the "Arch-betrayer," was once the second-highest-ranking officer of the ancient Dark Angels Space Marine Legion. Through a combination of arrogance and jealousy he would fall to Chaos during the Great Crusade and eventually become the leader of the Fallen, those Dark Angels who were corrupted by the Dark Gods and betrayed the Emperor.The conflict between Luther and Lion El'Jonson, the primarch of the Dark Angels, would precipitate the destruction of the Legion's homeworld of Caliban and the disppearance of El'Jonson for over ten standard millennia. Luther's actions became the heart of the terrible secret that would define the Dark Angels and all of their Unforgiven successors for millennia to come.Luther began his life as an acclaimed knight of a monastic brotherhood of techno-medieval knights known simply as The Order, who discovered the young and wild Primarch Lion El'Jonson living in the forests upon the Death World of Caliban in the late 30th Millennium. He became the primarch's saviour and took the man born of the forest with him back to civilisation.He raised the young Lion as his son within The Order, becoming a mentor, friend, and eventually a brother to the remarkable young man.When the Emperor of Mankind came to the world of Caliban and reunited with His long lost son, he gave Lion El'Jonson control of the Ist Legion of Space Marines, the Dark Angels, and charged him with leading them in the Imperium of Man's Great Crusade to reunite the human-settled galaxy.Luther, though too old to become a true Astartes, received certain genetic and biochemical enhancements through the use of advanced Imperial technology so that he might follow his great friend and brother to the stars alongside the other Astartes of the Dark Angels.In the end Luther would betray the Lion after allowing himself to be seduced by the offers of Chaos, rallying many of his fellow Dark Angels to his cause who had been left behind by their brethren to garrison the Legion's homeworld. They attacked the Lion's fleet as the primarch returned to Caliban following the end of the Horus Heresy on Terra.The titanic struggle between the two former friends resulted in the destruction of Caliban and the loss of the Dark Angels' primarch, as well as the escape of Luther's allies who had sided with the Ruinous Powers. Known as the Fallen Angels amongst their former battle-brothers of the Ist Legion, it became the overriding goal of the Dark Angels and all of their Successor Chapters after the Second Founding to hunt down every one of the Fallen and get them to repent their betrayal of the Emperor and of the Lion.Unknown to all but the supreme grand master of the Dark Angels Chapter, Luther was captured alive after the Fall of Caliban and was kept prisoner for over nine thousand standard years in the deepest dungeon of the Dark Angels' mobile fortress-monastery, The Rock, where he rambled insanely about the future for over 10,000 Terran years.However, these ramblings sometimes contain the hint of prophecy or the location of some of the Fallen, and every Dark Angels supreme grand master for many millennia consulted the maddened Luther, known only as the "Dark Oracle," in the Chapter's times of greatest need.Luther was recently freed from his prison during an unexpected attack of Daemons on The Rock after the birth of the Great Rift and the end of the Noctis Aeterna that was led by the Fallen Angel Daemon Prince Marbas.The Dark Angels believed the attack to have little purpose other than mayhem and destruction, but Supreme Grand Master Azrael knows the truth. The attack was intended to provide a diversion so Luther could be freed from his millennia-long captivity. Luther's current whereabouts are unknown.
