Andvardi, a.k.a. Alberich is the ruler of the Dwarfs, who mine the earth for gold. The great treasure they make from it is a source of conflict in both the Volsunga Saga and the Nibelungenlied. The gods trick Andvardi out of his golden horde to pay off a a debt. He curses procession of the gold, and all those who 'own' it will die miserably. The curse of the gold is central to many versions of the Norse sagas and legends.
