Greyhawk, also known as the World of Greyhawk, is a fictional world designed as a campaign setting for the Dungeons & Dragons fantasy roleplaying game. Although not the first campaign world developed for Dungeons & Dragons—Dave Arneson's Blackmoor campaign predated it by about a year—the world of Greyhawk closely identified with early development of the game beginning in 1972, and after being published it remained associated with Dungeons & Dragons publications until 2008. The world itself started as a simple dungeon under a castle designed by Gary Gygax for the amusement of his children and friends, but it was rapidly expanded to include not only a complex multi-layered dungeon environment, but also the nearby city of Greyhawk, and eventually an entire world. In addition to the campaign world, which was published in several editions over twenty years, Greyhawk was also used as the setting for many adventures published in support of the game, as well as for RPGA's massively shared Living Greyhawk campaign from 2000–2008.
Tomb of Horrors is an adventure module written by Gary Gygax for the Dungeons & Dragons (D&D) role-playing game. It was originally written for and used at the 1975 Origins 1 convention. Gygax designed the adventure both to challenge the skill of expert players in his own campaign and to test players who boasted of having mighty player characters able to best any challenge. The module, coded S1, was the first in the S-series, or special series of modules. Several versions of the adventure have been published, the first in 1978, and the most recent, for the fifth edition of D&D, in 2017 as one of the included adventures in Tales from the Yawning Portal. The module also served as the basis for a novel published in 2002.
