Casperin

Casperin is a small ghost who haunts the ruins of old Magincia in during the time of Ultima IV. It spoke briefly to the Stranger of all the haunting in the destroyed towne, asking if the hero knew why. When the Stranger responded "Pride," Casperin agreed, saying that pride is the surest measure of unattained goals, and directing the hero to seek out Heywood for the mantra for Humility.
