I did find a link on the Kojiki, and it was a good place to start. It's also very old and says little about how different temples work but focuses on the emperor and his solar mother cult, and that's good to know. I just keep finding anime references to a lunar spirit but almost nothing on his place in spirit worship. I feel like I'm trying to read a book on pagan tradition that someone ripped half the pages out of, and it bothers me. Since Kami are often described as nature spirits, I was hoping someone here had more information.
