Okay, take a look at the level "Shiver" in Myth II.
I just noticed this while I was muckying about in it's scripts. Look over near Shiver's camp (way up in the North West). First off there's a little cave there (mb for a ghol assault originally), but that's not my point. What's really interesting is what's behind the tents and krids. There's a big wall reminiscent of Muirthenme or some other ruined fortress. Behind it is a section of scorched earth (you'll have to turn off bounded observer to see this). Its got a slight spiral pattern and six little "pockets" in the ground (only four are really visible because the mesh edges are raised and the other two are on the mesh "wall"). They seem sort of like the pockets that you put crystals into in "Murder of Crows," however that didn't have a spiral.
The spiral reminded me of where Alric was trapped in TfL's the "Five Champions" level. I chacked and it indeed does bear a resemblance! Perhaps this level was originally meant to be in the desert, not south of silvermines? But I don't remember those walls in the Five Champions....
What do y'all think?
