Rary the Traitor is a Dungeons & Dragons sourcebook and module for the World of Greyhawk campaign setting written by Anthony Pryor and published by TSR in 1992 as the third Greyhawk "reference" module (WGR3). The work details the empire of the renegade archmage Rary, known as the Empire of the Bright Lands. The work includes historical background on the Bright Desert, and introduces the ancient Flan nations of Sulm and Itar to the setting. Information on Robilar, Rary's co-conspiritor, is also provided.
The information in the sourcebook section of the publication can be used in campaigns involving characters of all levels. However, the adventures contained in the module are designed for characters of levels eight or higher.
