In my first post, I showed screenshots of an area that I created by modifying an existing area from Mask of the Betrayer. Yesterday, I created an area from scratch. Here are screenshots of what I have so far.
The flying bats in the background are from Nihlar's A Cloud of Bats visual effect files. (Nihlar is also known as Amraphael at other forums.)
I'll be posting more screenshots as I add areas to the module.
