A thousand years ago a great war between the Dharzi and Melnibone eliminated the ancient race of sorcerers from the Young Kingdoms, and established the Dragon lords as masters of the world. Far to the north of Melnibone, the family of a lesser lord took the caverns of a tall, black island as their home, transforming the former laboratory of a Dharzi sorcerer into a magnificent abode.
Then, the Bright Empire began its inexorable decline, and the caverns were abandoned. Four hundred and fifty years have past, and something dark and vile now inhabits this isle, warping the natural order of living things and twisting their very beings into hideous monsters.
Lord Straasha summons the adventurers to the coast of Tarkesh, bordering the frigid Pale Sea and the unholy domain of forbidden Pan Tang. Visions of bloody waves ceaselessly haunt their dreams, presaging a doom to come should the heroes fail to heed Straasha's urgent call.
