I hadn't read anything about the jail in markarth until after I tried this. I used flames to provoke the people outside the locked door. They started attacking. The stuff mentioned in the trivia or glitches or whatever don't just disappear. I had miraaks staff, the corrupted skull, and other stuff. They wielded it all when they attacked me. They. wielded. my. stuff. I'm going to kill them when I load the last save.
