Alright, how about the Mecannis region? There's one. Cause mechanics and stuff

Gira region, cause they're all gears in a big machine? There's another.

Ravroth region? No specific inspiration, just sounds kind of gritty and solid.

Those are a few suggestions.

Also, in regards to the world, it kind of sounds like it'll be a bit samey. I know I didn't get the whole picture, but surely there'll be a few places that don't treat pokemon badly? I mean, dude's gotta have a holiday sometimes. There should be at least one or two places where you can get away from it all, maybe in the mountains or something.
