Pearl Magic

Pearl Magic were special pearls created by Naga.

The imperfections of a soul that joined the Akasha were cast out from it, to purify the Akasha.

The imperfection was placed in one naga oysters to be forever sealed away from naga race. The oyster imprisoned the impurity in a pearl, thus from impurity comes purity, and the pearl is itself part of the purity of the Akasha.

There were more powerful and secreted pearls, the Black Pearl.
