Map (currently only for the Griffin Empire).

I made a map, but I'm having trouble with the underground world. I can't figure out the lighting. I place castles and heroes in the darkness, and when you look closely, you can barely see them. Also, the landscape is invisible. Can you help me? And also, where should I place the capital of Eagle-Shale – in the underground world or the regular world? :confused: I also built all the cities, but I named them after the capitals in Heroes 5.
