With the Horns of War calling troops both dead and alive to battle, Keera and Merick must return to where their adventures first began, where veiled behind a mask of dark magic and driven by an unquenchable thirst for revenge, the blackest of mages plots their demise. Weaving a deadly web of tricks and traps he draws them ever closer to his lair, and like a motionless spider he sits and waits for the moment when they have to face their worst nightmare. The Nemesis of the Valkari.
