This post is about the celestial spirits from the show Fairy Tail. The celestial spirits are beings that reside in the celestial spirit world. They are very powerful, and can be summoned by a celestial spirit wizard. The spirits can go to the human world for a limited time, but they have to return to the spirit world when they run low on magic energy. If they are in the human world for too long, they will disappear. They can also be banished from the spirit world by the Celestial Spirit King if they break the rules and kill a wizard they have a contract with, even if it's accidental. Celestial spirits can be summoned by a celestial spirit wizard, and they have to agree on a contract with them after the first time they are summoned.
