Descent into the Depths of the Earth
Descent Into the Depths of the Earth is an adventure module for the Dungeons & Dragons (D&D) fantasy roleplaying game coded D1–2. It was written by Gary Gygax, and combines two previously published modules from 1978, the original Descent into the Depths of the Earth and Shrine of the Kuo-Toa. A sequel to the first two modules, Vault of the Drow, was also published in 1978. All of these D-series modules were produced for use with the 1st edition Advanced Dungeons & Dragons (AD&D) rules.

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 to 2008.
Supplement I: Greyhawk, written by Gary Gygax and Rob Kuntz, was an expansion of the Dungeon & Dragons rules that contained no material about the Greyhawk campaign world other than two brief references.
