I haven't been able to find it in the main hall and I didn't see any mention of it's location in the walkthrough. Is it on that level and I missed it or is it someplace else?
I'm puzzled! Your walkthrough must be different than mine as I don't have a "Puzzling Room" ?? Is yours the Game Banshee Walkthrough? If it is please tell me the room number. If not please try to describe the location of this room....
Ok, room 55, in the walkthrough is actually titled "Stairs to Upper Halls" which is why I couldn't find it. And the problem is with the wording as it leads you to believe the key is in the Main Halls, right? But you will only find it after you come down from the Halls of Light! Wierd, ay? so just pass by 55 for now....
