In J. R. R. Tolkien's fictional world of Middle-earth, The Endless Stair rose from the lowest dungeon of Moria to Durin's Tower at the summit of Celebdil. The Endless Stair was of such legendary status among Dwarves that some considered that it had never existed, but Gandalf confirmed its existence to Gimli when he recounts his battle with Durin's Bane (a balrog).
