Elric of Melniboné
Stormbringer was a fantasy tabletop role-playing game published under license by Chaosium. Based on the Elric of Melniboné books by Michael Moorcock, the game takes its name from Elric's sword, Stormbringer (though one edition was published as "Elric!"). The rules are based on Chaosium's percentile-dice-based "Basic Role-Playing" system.
