Anton Mordrid is a Wizard (fantasy) sent to Earth by a being called the Monitor, to stop the evil wizard Kabal from opening the gate to Hell. Kabal needs the Philosopher's Stone and several alchemical elements to complete the spell and open the gate, unleashing his minions from the Four-dimensional space upon the Earth. Mordrid watches for signs of Kabal's presence for 150 years; as the time of their epic battle approaches, Mordrid assumes the role of a criminal psychologist, and becomes the mysterious landlord to Samantha Hunt, a research consultant to the police.
