Roll the Bones: Role Call 28: Unusual settings

What’s the most unusual setting in which your game has been set, and what makes it so unusual?

I’ve sat and thought about this for as long or longer than any online meme warrants, and the bottom line is that I don’t think I’ve ever done a really weird setting.
Nothing underwater, nothing airborne, nothing in the land of dreams, or London Below (which wouldn’t be unusual even if I had).
Nope. Weirdest stuff I’ve ever come up with is probably no worse than walking around on the World Tree in Nobilis (which doesn’t count, because it’s part of a ‘standard’ setting).
Interesting observation, but there you have it.
