The Purity Heart is an item created by Merlimbis. The Purity Heart was made to counter-act the Dark Prognosticus. The Purity Heart is created to be the embodiment of love, the only thing believed to stop the Chaos Heart. Once the Pixl Rebellion left the Tribe of Ancients declining, Merlimbis decided that the Purity Heart has to be guarded by someone else. So, Merlimbis divided the Purity Heart into eight Pure Hearts and they were taken to different parts of the meta-universe. Once all eight Pure Hearts unite, they restore the Purity Heart form. The Purity Heart is never seen in the game, because when it restores, it is covered by a blinding light.
