In the World of Greyhawk campaign setting for the Dungeons & Dragons roleplaying game, Rary of Ket is an archmage and political leader.
He is also called Rary the Traitor, a former member of the Circle of Eight. He was responsible for the deaths of Circle members Otiluke and Tenser at the end of the Greyhawk Wars. After his betrayal, Rary fled with his ally Sir Robilar, to the Bright Desert, where he established the Empire of the Bright Lands.
His younger brother, the renowned sage Arkalan Sammal, who resides in the Free City of Greyhawk, has renounced Rary, as have most of his former allies.
However, during the Living Greyhawk campaign, many adventures set in Rary's home region of Ket referred to him as Rary the Patriot, and Ketite NPCs often insisted that he was not evil, merely misunderstood.
