From publisher blurb:
Deep in the fetid swamp lies abandoned Nekemte, ancient serpent man city of the Jade Empire and home to the royal house of Nekemte - cruel, tyrannical sorcerers and practitioners of necromancy, corrupted cultists of Yul. The great swamp consumed Nekemte following the fall of the Jade Empire, its buildings crumbling and falling into decay. Throughout the centures, terror of the sepent man sorcery hung over the ruins, and shadowy creatures stalked the crumbling edifices at night, feeding on the warmth of the living. A party of looters recently dared the ruins and stole into the lower tombs where they unearthed the Arimax Stone, an artifact of great power, in the process unwittingly awakening an ancient, slumbering menace...
