This is a map I will be using for my D&D 4E group. It's The Mortuary from the old 2nd Edition D&D setting Planescape module called "The Eternal Boundary". It's not perfect but I think it will work. There are 2 more levels that I am working on but I wanted to share what I had so far. The glowing stones are portals that the dustmen place the bodies in to send to different planes. The other two levels will have less empty space.

Looks pretty good to me. I like those portals.
Very original design... would be cool to see the building from thee outside.
