Wow, that is phenomenal! Great blend of Victorian-esque elegance and the macabre! I especially love the entrance, the graveyard with bioluminescent flora and then grand marble entrance with a coach out front, felt like the beginning of a classic horror movie. The main hall is amazing too — love the arches, all the bookcases and cobwebs, the grand statues!
