Caves of Chaos.JPG
I'm still tinkering with it slightly, but I've started running the game using this map. It's a 50px:5f grid scale, so the detail isn't super sharp, but it's also a 6900x4500 image, and I just didn't want to go any bigger. I saved it as a 30% quality JPG though, so I'm actually pretty pleased with how legible it is, all things considered.
As the game progresses, I might cut out 100px:5f battlemaps of the individual lairs for each of the tribes.
