During the testserver that implented the Pits of Inferno quest Aeldene Stonebridge was rewarded by Knightmare for solving big parts of the questline. He teleported together with her to an area that can not be reached. However it is implented in the game and tracable on the map. In the room north of this area are different rooms with switches for "lag", "kicks" and more. Screenshots of this room got lost over the years. As far as known no one has entered this room ever since.
