Xavor'Khrazak

The Chaos Space Marine known once as Xavor'Khrazak is no more. All that is left now is the Kaos-Bringer, the Abyssal Destroyer, the Living Tide. A hulking abomination of uncontrollable mutation and mindless destruction, Xavor is seen as an avatar of Chaos itself, and in comparison to the truth, the most easily comprehensible and most sane infinitesimal of what will replace Falsespace as 'reality' in time...

History
Very little is known of Xavor's backstory. His name and reports of only ever speaking in either Colchisian or the language of the Gods themselves, implies that he is Colchis-born. Whatever the case, the story goes that in one cataclysmic battle, the Son of Lorgar was broken beyond repair and on the edge of final release into the Empyrean. However, rather than die, the brother demanded internment in a Dreadknought sarcophagus, one tailored to his particular desires, one that would bring him closer to his Gods and allow him to continue to serve in their armies. His final wish was fulfilled, and Xavor became the abomination he so desired to be.
