One of the most spectacular items, this is the key to Erethun’s laboratory, the fifth floor of his tower, now missing. The key can be placed in the keyhole of any normal-sized door. Once the key is turned, the door opens into The Lost Tower. Leaving this room, the bearer of the key can open the door to any other doorway in existence he or she can picture. Without a clear picture of where the bearer wishes to go, the door will open on a random doorway usually within a mile or so of the desired location.
Current whereabouts and owner unknown.
