You died in a bar-room brawl. A day later, you were brought back to life by Alliance necro-scientists, only it wasn't just you that came back. You are now part undead, part nanobot. You have no regrets over killing the scientists who did this to you. The Union of Mandated Peace once found you passed out after a night of heavy drinking and, thinking you were dead, decided to bury you in a shallow grave.
