Lord Dust

Lord Dust is a lich in the service of Orcus. After failing to stop the Challengers of the Unspeakable from defeating Zirithian, Orcus gave his phylactery to Tephra, who exposed it to the energies of the Far Realm, transforming Lord Dust into a creature knonw as a void lich. With these new powers at his command, he was sent to the lair of the silver dragon, Orantis, where he was once again defeated by the Challengers.
