Grave Error

From the introduction: An adventure for Knave or Maze Rats Publisher's blurb: This is a low-level adventure, but do not be fooled by that. It is certainly no push over! In this adventure, the heroes need to find and investigate a lost shrine, recently rediscovered by a local fisherman. What lies in this mud-filled, stinking and half-submerged religious site [is] for your players [to] discover.
