After avenging his parents' deaths by murdering the police officer who shot them, he locates the Himalayan city of Shambhala, inhabited by a sect of monks that worshiped the concept of evil. Prometheus discovers the monastery has been built on an alien spaceship, and the leader of the sect is one of the creatures from the vessel. He kills the alien and obtains the "Ghost Key", which opens a portal to the "Ghost Zone".
