From the back of the book: Within the near impenetrable inner circle of the Corsair Mists, the White Ship has been called to its once proud dock by the dark sorcery of Molo of the 13 Wives. The final conflagration is at hand as the adventurers assail the towering boarding stair, fight their way through the ship's countless enemies, and finally enter the grand worship hall of the two greater sea gods, all in an attempt to thwart Molo before he can bring on an end of days.
