Battle of the Peak
- " ...Those that looked up from afar thought that the mountain was crowned with storm. Thunder they heard, and lightning, they said, smote upon Celebdil, and leaped back broken into tongues of fire."
- ― The Two Towers, "The White Rider"
Gandalf pursued the Balrog from the depths of Moria. On the peak they fought for three days and two nights from 23 to 25 January T.A. 3019. During the battle, Durin's Tower was destroyed and the entrance to the Endless Stair was blocked. In the end, the Balrog was cast down and it broke the mountain-side as it fell. Gandalf himself died following this ordeal, but was later sent back to Middle-earth with even greater powers as Gandalf the White.
