I am Alpharius. Or, perhaps, I am my twin brother Omegon. We wouldn't give you the luxury of knowing. Or would we? As you can tell, I am a master of lies, manipulation, obfuscation, deception, and psychological warfare. My sons in the Alpha Legion follow suit; Hydra Dominatus. We were loyal to my father, the Emperor, but I discovered that Chaos could be destroyed by allowing Horus to win... thus, I sided with Horus "for the Emperor." Despite being a traitor, I am perhaps his most loyal son.
