I am trapped in Durlag' Tower LVL 2 in the bedroom. I have killed the doppleganger of the big bad dwarf, but all of the doors have closed and
locked on me. For some reason the runestone from illane is not working on
the southwest door like I have been told it is supposed to. All of my
people are trapped, and Imoen has close to 90 pick locks but not working?
What can I try next???

The way I understand it, if you remove and replace the red wardstone in the southern part of the bedroom, it should open up the doors in the north and south of the room. I hope this helps.

Did you leave the building or rest on that level? There seem to be several bugs there that lock up the doors so you can't pass...

I have tried to put each wardstone in every place. I have Kiel(green), Fuernebol(orange), and Islanne(red). After reading last post, I tried to put the red wardstone in the table, and nothing happened. The only other place I can place it without recieving a fireball for my efforts is the bureau against the north wall. The two table to the northeast get me the fireballs. I have saved the game, and rested on that level. It is not possible to leave the building because I can't get out of the bedroom at all. All three doors are locked magically as they resist lock picks.
