I'm guessing you meant to include the Chinese Zodiac critters?
Probably. I just remember there are multiple pantheons and just posted the first three to show up on their wiki. It's really the same problem I have with Marvel and DC comics. There's multiple pantheons, with "equal" leaders, but only the Asgardians/Olympians (Marvel/DC
) are discussed in any meaningful way. At least in OOTS it's one storyline and one writer so it isn't as annoying.
