The island kingdoms of the Plenn Archipelagoes have been ravaged by wars lasting more than a hundred years. The final battles were fought by wizards of prodigious power . . . and no restraint. Entire islands turned into volcanoes and on others even worse catastrophes befell the inhabitants . . .

Itinerant warrior-wizard Durril and his stodgy apprentice Arpad Zen arrive on the island of Loke-Bor looking for work. Durril is a specialist in exorcism and the castle of Lord Northdell is a fitting challenge. The castle and grounds are infested with the menacing spirits of the dead legions that once occupied it. Seeing a quick profit Durril agrees to rid Loke-Bor of all remnants of the Spell Wars . . . not realizing the deal also includes doing battle with the evil and reclusive wizard Rahman'dur.
