Hello, it's me again! Sorry for overposting in this part of the forum, but I again need your help to find something that I don't know if it exists.

I have the idea to create a map of an underworld, because my next campaign will be in a cavern, where there are towns, and active lives, just like in Matrix, but in medieval times... Is there a tuto for this style of maps?

Thank you very much if you can help for this!
