Angband

[dawn_felagund]

The army from the West at last destroys the lair of Morgoth and, under the tumults of war, the shape of the land begins to change.

Thus an end was made of the power of Angband in the North, and the evil realm was brought to naught; and out of the deep prisons a multitude of slaves came forth beyond all hope into the light of day, and they looked upon a world that was changed. For so great was the fury of those adversaries that the northern regions of the western world were rent asunder, and the sea roared in through many chasms, and there was confusion and great noise; and rivers perished or found new paths, and the valleys were upheaved and the hills trod down; and Sirion was no more.
