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 over 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.
Mordenkainen is a fictional wizard from the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game. He was created by Gary Gygax as a player character, only months after the start of Gygax's Greyhawk campaign, and is therefore one of the oldest characters continuously associated with Dungeons & Dragons.
Castle Greyhawk is one of the central dungeon settings in the fictional World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game.

In 2005, Gygax announced the release of "Castle Zagyg," his new treatment of the dungeon.

The Free City of Greyhawk, also known as Greyhawk City and the "Gem of the Flanaess," is a fictional city-state in the World of Greyhawk campaign setting for the Dungeons & Dragons fantasy roleplaying game. Since the setting was originally published in a folio and then again in a boxed set that were both titled World of Greyhawk, the word "Greyhawk" is often used to describe the entire campaign world setting, although the proper name for that part of the world is the Flanaess. Sometimes the lands controlled by the Free City are also referred to as Greyhawk, though the proper term for the region is the Domain of Greyhawk.
