Brütal Legend follows the story of Eddie Riggs (voiced by Jack Black and named after Eddie the Head, the mascot of Iron Maiden, and Derek Riggs, the artist who created Eddie), who is the world's best roadie for the world's worst heavy metal band. The game begins one night before a gig. As Riggs is tuning a guitar, an accident happens and he starts to bleed. His blood drips onto his cursed belt buckle, which is really an amulet for Ormagöden, "The Fire Beast, Cremator of the Sky, and Destroyer of the Ancient World." Ormagöden awakens and transports Eddie into a heavy metal and Nordic fantasy inspired alternate history where demons have enslaved humanity. Eddie comes to learn that the fantasy world was created by a race of ancient Titans who left behind numerous relics and instructions for the following generations to use, but neither humans nor demons could decipher their meanings. Only Eddie, due to his roadie skills, is able to make sense of their meanings and can put the Titans' wisdom to use.
