There's this forlorn rundown prison area in what I think is Oblivion, but I don't recall the name or where it is. It's like the section in the Imperial city prison that has no lighting, adjacent to the one that is in use. However, this one is more like a cave, and very distinctive.

It's got several cells in it, and plenty of corpses etc. It's not the abandoned prison in Skyrim somewhere in the southeast between Whiterun and Riften. It's something else. I don't want to spend hours looking for it, so I thought I'd ask here. I've got a feeling it's in the southwest part of the map, but can't confirm this.

Anyone got any ideas what this place could be?

Thanks in advance.

MT3269: There are several places in Shivering Isles that would fit that description.
