A sinister mage has unleashed the power of an ancient artefact on the land, an artefact that drains the world of magic. Worse yet, the evil armies that pour through the artefact may bring about the end of the Castle of the Three Suns. In a final desperate gambit to turn back the tide of doom, the Penhaligon knights ride far and wide to defend all of Mystara from this magic menace. Meanwhile, Johauna Menhir sets out on an impossible quest to foil the malevolent mage. She seeks to enter artefact and, with her immortal forged sword Pearce, slay the wizard Auroch. The Penhaligon Trilogy is the first set of novels to explore the Known World, the most famous campaign setting for the Dungeons and Dragons role playing game.
