Southwest of Winterhold, in Bleakcoast Cave, there is a part of the cave guarded by frost trolls where you will find parts of a skeleton hanging from the icy ceiling. On the ground below it is a Steel Greatsword of Weariness. This is a reference to Star Wars: The Empire Strikes Back in which there is a scene where Luke Skywalker is stuck to the ceiling of an icy wampa cave and must use the Force to retrieve his lightsaber to cut himself free.
