If i may make a suggestion? the map looks really cool btw, nice work on that!
You have the village where people would have the open vantage point, with the coaster tracks in the distance that makes an impressive vista.
Behind it, basically where it says "the congo" on your map, there is a cliff and trees. I think, and it could maybe be an expansion for later, that cliff-spot is your drawpoint.
It's the prime spot, so to speak. I imagine some whiteish, chalky cliffs, similar to the Dover area in England. Topped with some sort of experimental hut/temple combination.
Just some thoughts. Keep up the good work!
Edit: Maybe a diamond mine, and remains of an Empire built upon it.
