The Circle of Eight (formed from the earlier Citadel of Eight) is a fictional group of wizards in the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game. The Circle was originally created by Gary Gygax around 1975 as an alliance of most of his own personal Dungeons & Dragons characters. In 1988, the concept of the Circle was redeveloped by TSR as part of a new storyline for the World of Greyhawk campaign. This new Circle of Eight became a powerful cabal of wizards based in the Flanaess, the easternmost portion of Oerik. Its chief purpose seemed to be the preservation of the balance of power between the forces of Good, Evil, Law, and Chaos in the Flanaess.
