Lil note to myself:
Finished up the mythical creatures guidebook page today. I may revise the definitions of some of them later but for now this is good.
“Kimaira” and “Kamaileo” are not-Greek as I already explained.
“Umao” is from umay/homaio, the somewhat griffin-like bird of Turkic/Persian mythology. I was looking for a traditional mythology about griffins beyond the heraldic use that I might find a name in and it was kinda hard to find one but then I remembered about those and it’s a reasonably good fit.
