Ancient South America (Aztec, Inacn, etc): Aztecs were big astronomers. A chance for KI to give astral schools a bigger role. Ancient South Americans studied stars a lot, so they could use this world to give the star school more spells, hopefully STAR DRAGON!! :D
Ancient Greece: Big on astronomy too and KI could use the legends to give astral schools new spells (ie moon spell based of Selena goddess of the Moon)
I'd love to hear other ideas on new worlds and comment on what I posted. Also please try to base your ideas off ancient cultures.
