The Mages Guild is a joinable faction in The Elder Scrolls Online. Players may join the Mages Guild regardless of their Alliance, much like the Fighters Guild, as they have not taken sides in the Alliance War in Cyrodiil. Reputation with the Mages Guild can be increased by collecting special lore books in Alliance territory and in Cyrodiil. The Mages Guild questline revolves around the Daedric Prince of Madness, Sheogorath. The Mages Guild has headquarters in the region of Rivenspire in High Rock, and The Rift in Skyrim.
