Osiris is the Egyptian Lord of the Underworld, and is a recurring character in Jaden's Adventures. In Egyptian mythology, his evil brother Set the God of Chaos killed him so that he could rule the land. But Isis, Osiris' wife and sister brought him back to life long enough so that she can concieve a baby and thus, Osiris' son Horus was born. He fought Set, and ruled the land of the living while Osiris became lord of the Underworld.
