Thanks Jay. That's by Infernal. Its a freebie set of parts you can mix, match, and move around to make castle interiors. The linked pic was made with Caleb's Dark Ages sets (marketplace)--those are great for fantasy settings too and work the same way. I really like these modular "building kit" sets because they are so flexible and you can use them over and over again and not have them look the same in every pic.
