Avathar

[dawn_felagund]

In the deep shadows of Avathar, Melkor and Ungoliant plot the destruction of Valinor.

Thus unseen he came at last to the dark region of Avathar. That narrow land lay south of the Bay of Eldamar, beneath the eastern feet of the Pelóri, and its long and mournful shores stretched away into the south, lightless and unexplored. There, beneath the sheer walls of the mountains and the cold dark sea, the shadows were deepest and thickest in the world; and there in Avathar, secret and unknown, Ungoliant had made her abode.
