In 1982, TSR published the module named “Against the Cult of the Reptile God” with the module code “N1”. It was written by Douglas Niles and published as a 28-page booklet. The module provides a town as a home base for adventure as had been previously seen in a number of other modules but for the first time introduces a threat within the town itself. In addition it provides a challenging underground adventure and a number of plot suggestions for further adventures in the area should the player characters prove successful.
This conversion guide allows DMs to run the original module with 5th Edition rules and provides a reference sheet for encounters.
