Really it's a fantasy realm with an approximately medieval atmosphere - I'm sure you've played the type before! Pokemon don't change all THAT much. If you have any questions, I'll be glad to answer~

Feel free to use the real world as a frame of reference. That's one of the nice things about using an alternate-earth.

Also, Kalos/France is to the west. The area around Geosenge is a wasteland, but it's a small region in an otherwise very large part of the world~
