It was written by game designer Mike Carr and was first published in 1979 by TSR, Inc. The module details a hidden complex known as the Caverns of Quasqueton. Reviewers considered it a good quality introduction to the game that was written in the so-called dungeon crawl style, where the primary goal of the players is the exploration of a dangerous labyrinth to battle monsters and obtain treasure.
