I've been doing some dabbling in worldbuilding lately, and gained an interest in mythologies NOT related to the Greek, Roman, Arthurian, and Norse. I watched an episode of Halfworlds. It was crap, but talked a lot about Indonesian mythology, which I thought was pretty damn interesting.
Do you have any favorite characters, concepts, creation stories, etiology, or folktales, from little-known mythologies around the world?
What about your favorite literary mythologies? And please don't go the Lovecraft route, I'm interested in something new.
