Kuu

Kuu is the term for the religion and the goddess of the moon that supernaturals believe in and worship. Supernaturals have long since decided that the cause of their condition is the moon, due to them all being connected to it in some way. It is unknown if this is true or not; it's as good a guess as any, as there seems to be an innate, inexplicable magic inherent in all supernatural beings that normal creatures like humans and animals don't seem to share.

Supernatural society used to worship Kuu much more strongly, but after the attempted genocide of supernaturals in the early 1800s, their culture and, therefore, their beliefs were nearly wiped out. This renders Kuu a reconstructed religion- many of the old texts from secret supernatural societies were destroyed, but through what remained and what was passed down through the legends of old supernatural families, much of Kuu and it's superstitions and beliefs have been pieced together.
