An extreme environment
It's cool, and I like the fact that you can make a map for its own sake, that your worldbuilding can arise from the visual concept alone. Nice
This is fun. How do the people get provisions? Do they have farms and animals for food? Is this an island or a continent? Why do they need outposts?
It was just an idea on an extreme environment. They have greenhouses and underground farms, it's a continent with hostile neighbours.
Cool! Any more info on the crimson city?
Neat! Is this supposed to be in some extraplanar area?
