Need help finding locations

I've long known that key terms never bring you what you need to find in-world, but I didn't think I'd have this hard of a time finding a location for inspiration on a project. So, I come to you all to pick your brains.

I am looking for a place that inspires dark, evil, insane, scary, spooky, creepy... well, I think you get the idea here. I would like the whole atmosphere, but would happily work around the "whole" concept if I can just land somewhere that immediately says, "This is the creepiest/darkest place you have ever been in SL."

Any ideas? TIA

hiya,
try obscurum .. amazing light there )

Depends how inured you are to 'creepy' and 'dark.'

Try Bentham Forest.
