Hey! Let's make Lovecraftian fantasy setting with Dwarves that went literally insane from some eldritch horror! And Humanoid Fae/Elves being corrupted by dark magics and worshiping Chutulhu style monsters... Now that would be fun Dark Fantasy setting...
Well, according to the story line, the local civilization exploited it after arriving in the area and extirpating the vicious, savage, skin-wearing natives who had been living in the ruins of a giantish civilization.
The perspective is kind of awkward and dizzying to look at, but I honestly can't think of any good way of doing a map like that so not going to say much about it. Great work on the details, can tare at this for quite some time.
Now that's seems to be one really interesting town. Sure, the perspective adds even more, but the town itself does already look like a super-fun place to be. --> Great work. (And also it's nice to see we've still got some nice river's around, being extra considerate not to flood the pit with people in it, even though passing so sharp ^^)
