Beasts are variations of angels, demons or ghosts. Angels and demons are
souls without a body in a corporeal form, so the souls usually take the
appearance of their former bodies. A beast is simply any soul that does
not have a humanoid appearance.
Beasts can be anything from a humanoid with horns and a tail to a nine
tailed fox. One who is a beast is still an angel, demon, or ghost. Most
beasts can shape-shift to appear more human and usually have two forms-
their actually beast form and thier humanoid form.
