I'm curious: In the first room for the initation (the one with the weights) there is a closed door with a small room in the north. How can I get in there? I tried to 'bug' my way through with teleport, but no luck. The room doesn't open when you finish the dungeon, either. I checked several walkthroughs but I don't see the room mentioned anywhere.
Interesting. I never noticed that and from what I can remember all the rooms are accessible. You've finished the entire dungeon/quest without opening it?
