By accident my thief stumbled upon a secret door in the Round Table room on the first level (past the Ettins) of Dorn's Deep. Inside is a floor puzzle, which I solve and get a message saying "You hear a noise coming from the Round Table room." I go back to the table room, but see nothing different about it.
Does it really do something, or is it just faking it?
