hi! this sounds cool, so might as well throw in a few locations that could be cool
Pyramids of Unida
(based on the Pyramids of Giza)
This spot would probably be somewhere in the middle of the beginning of the story and the end. In this area, there is stuff, like a Pokemon Center and Shop, a few homes, and possibly a Souvenir Shop. Inside the Pyramids, there's a small lobby area, and then you can delve into the Pyramids.
Inside the Pyramids, there would be a lot of rooms containing puzzles, increasing in difficulty. At the end of each room, there would be an item, ranging from stuff like Nuggets to more expensive things like a Pharaoh's Crown (or something) and at the end of the last puzzle is a very rare Pokemon.
That pokemon would be Dehinx (desert sphinx in yoruba)
It would be based on the Great Sphinx of Giza, with the head being (of course) the Sphinx, while the bottom being 4 small pyramids (basically acting like legs) being held up by small, black creatures.
Here are some of the stats.
When you encounter it:
