A relic sacred to the Rat God lies protected beneath a temple in Ilthmar. When Lankhmar’s Overlord learns of this plot, he dispatches a selected party of cut-throats, sorcerers, and alley-fighters to recover the relic before the scheme of the Rat God comes to fruition. But to succeed in their mission, the party will have to infiltrate the deepest depths of the Rat Sect and overcome a multitude of unexpected and dangerous guardians. Do they have what it takes to fulfill the Overlord’s request-or willthey each end up another rat-gnawed corpse in the shark-infested waters of Ilthmar?
