Map (currently only for the Griffin Empire).

I made a map, but I'm having problems with the underworld. I can't get the lighting right. I place castles and heroes in the darkness, and when you look closely, you can only see them. And the landscape isn't visible; help me. Also, where should I place the capital of Eagle-Shayl – in the underworld or the regular world?:confused: I also built all the cities, but I named them after the capitals in Heroes 5.
