The Sword and the Sorcerer (1982)

In a dark epoch of sorcery, the murderous megalomaniac King Titus Cromwell awakens a demonic necromancer, Xusia of Delos, to usurp the throne of the benevolent King Richard of Ehdan, enslaving his daughter, and forcing his youngest son Talon into exile. One violent decade later, Talon--now a great warrior wielding a magnificent triple-bladed sword--returns hell-bent on revenge. Unbeknownst to him, however, the evil sorcerer is alive, gathering his strength for the ultimate battle. Will the dauntless adventurer restore peace to the long-suffering kingdom? Is this the return of the lost prince?—Nick Riganas
