Portal:Dungeons & Dragons/Selected rulebook/8
Tomb of Horrors is a 1978 adventure module for the Dungeons & Dragons role-playing game, written by Gary Gygax. It was the original tournament dungeon used at the Origins 1 convention. The Tomb of Horrors is a 2002 novelization of the adventure written by Keith Strohm.
Numbered "S1," the module was the first in the "S" (for "Special") series of modules. It was followed by S2: White Plume Mountain, S3: Expedition to the Barrier Peaks and S4: Lost Caverns of Tsojcanth. Although part of a series for the World of Greyhawk campaign setting, the four modules had no connecting plot or theme. Tomb of Horrors is one of the most famous Dungeons & Dragons modules. It was also the first module to include a numbered series of drawings, each of which would be shown to the players upon entering a certain area or encountering a certain fate.
