Tired of the constant fighting and bloodshed of the Crusades, the young duke Alcedor returns to his homeland of Upel. However, the ancient tome known as the Necronomicon, a book written by a madman rumored to hold great power, has been brought to Upel around a year before Alcedor's return. As a result, hordes of monsters have been ravaging the duchy, with Alcedor having to help defend the town of Darsov from an attack upon his return. Alcedor and the town's defenders successfully drive off the attackers, though one of the monsters manages to flee.
