Continents and remarkable islands in the natural world.
In no particular order, Aibun is the corpse of a god that landed and became an island; Noress is a feral land of trees and faeries and monsters; Elsee is a mountainous continent with a lot of competition amongst the locals pretty much no matter where you go; not-nearly-fleshed-out-enough Saban and Nocwen (though both are developing a rich prehistory and I even have a couple of other places without articles because they're that unimportant, like Jupiter, which was a wasteland that ended up being a god's trashcan and produced Halfmen and therefore Humans and Halflings .
Noress and Elsee both have categories with more articles with more trees, as well. I'm getting there with others.
