Jason Wolfe awakes in a strange bed in a strange apartment, and finds photographs on the walls appearing to show himself over time as a different person, a Slayer to the Emperor of Albion. He finds a code-locked chamber full of grotesque trophies, his winnings from the tournaments he has been engaged in, and realises that he has somehow switched worlds, into an alternate universe.
