Unions are the five factions lead by the Five Foretellers. The Five Foretellers are Keyblade Masters, apprenticed to the same Master and each bestowed with a copy of the Book of Prophecy. Each Foreteller has an associated animal, and hides their identity behind a mask representing that animal. In addition the Foretellers represent one of the deadly sins, as hinted by their names. The two sins not represented in the Foretellers are "Luxuria" (Lust) and "Superbia" (Pride).
