From the introduction:
The year is DR (Dominarch's Reckoning) 777, and the Dominarchy is in chaos. Land-dwellers war with the sea-dwelling sahuagin. Monstrous wyrm are attacking farms and mines from their home in the bottomless rift that tore the Dominions in half thirty years ago. Famine and shortages weaken the land, and civil war threatens to tear it apart. Worst of all, a frightening, incurable new disease runs rampant through the Dominions, a magical sickness known as The Hierodule Plague, which twists flesh and mind to create monsters out of normal beings.
For characters 7th - 9th level. This adventure adapts some concepts from the Warhammer Realm of Chaos and is presented with a "splatterpunk" feel. The adventure map is not provided but is referenced as the "House of Cards" map from Dungeon (Issue 19 - Sep 1989).
