There are eight avatars, known as the Sleeping Gods (or the player-given name "celestial avatars"), represented on a stellar map. Each of them is tied to one of the eight elements of Vana'diel and has a constellation in the night sky. The Avatars themselves sleep within Protocrystals hidden across the world, and if an Summoner defeats them in battle they may form a pact with the creature and are allowed to summon a part of their power (in the form of an avatar) within the normal world. It is said when the sleeping Avatars awaken they will return the world to its true state. However, this does not apply to Alexander and Odin, who are the subjects of a separate myth.
