The Mages' Guild, or Mages' Union,[citation needed] was one of three factions within Dalaran, including the Kirin Tor and Sorcerer's League, which tried to hold back the forces of the Scourge during Arthas' siege of the city during the Third War.[1] These three factions were also the ones trying to prevent Kel'thuzad from summoning Archimonde outside Dalaran (or simply trying to destroy the Scourge, unaware of the summoning).[2]
