The Celestial Keep is a location accessible by activating the Cursed Skull from Murgo in the Fable II DLC See the Future. Upon activating the Cursed Skull the hero is transported into the ruins of a large stone cathedral. Here the Hero encounters a stone skull-shaped tomb which asks the Hero for help. Nearby is a Cullis Gate that will become active once the Hero has removed the curse. The Cullis Gate will allow the player to leave the area, and will return them to the location they were when they activated the skull.
