Not sure where to post this really, or if anybody here would actually know, but one day I was strolling through Mist checking out houses and ran across one that had black interior with faux elevators. It was a medium [FC] house, if that helps. Sorry I can't be more descriptive, but if you know it, you know it.

I can't remember where it was so I'm hoping somebody here might know what I'm talking about.

Currently going through each ward to find it myself.
