Angels come from Celestia, also known as the Angel Plane, or Sacred World. The first angels chose to reveal themselves to a Priest named Diale, who gave her coronet to Tamarin, the first guardian angel. From then on, it became customary for Priests to receive guardian angels.
Although they resemble humans in shape, angels are otherwise unique in their appearance. Their bodies shine with points of sparkling light; instead of walking or flying, they float softly from place to place.
