Warhammer: the Emperor's Chosen I Became the Leader of the Heresy

In the forty-second millennium of the Empire. Virgil is just an ordinary time traveler. He became a Primaris Space Marine for the sake of his home, his family, and his less-than-loyal beliefs. He never imagined that he would be corrupted by the Evil God of Chaos, yet be blessed by the Emperor. Nurgle's plague took root in his very bones. The Emperor's golden flames burned from his spine. His flesh alternates between decay and regeneration. Every breath is pain, every heartbeat is betrayal. Every time he uses the power of chaos, he pushes his soul away an inch. But he never stopped. Years later, Virgil stood on the pedestal of the empire. His whole body was filled with the evil aura of chaos, but he was named a living saint. "You know, although I lead heretics, collude with foreigners, and murder my own people." "But I have always been the Emperor's most loyal follower!"
