Okay, so I looked through the Thread Reference and didn't find a thread for this. And I think this deserves it's own thread.
God Enel and the People of the Moon. Which refers to to the three races that came from the Moon: Skypieans, Shandians and Birkans.
The three races used to live on the Moon in a city named "Birka". Some time ago (over a 1000 years) they ran out resources and left for the Earth. The Skypieans and Birkans settled on sky islands and the Shandians on the island of Jaya.
And a related subject: Enel. He now lives on the Moon and controls an army of robots. When will we see him again? Also, what's the deal with the drum thing on his back? My guess is that he ripped off his wings and inserted that thing in their place. (Hopefully Oda draws him as a child so we can get that cleared up.)
