Sauron returns to Mordor after the Downfall of Númenor
Event Type: General
Age: Akallabêth/Last Alliance
An event in aftermath of the Downfall of Númenor; see that entry for an overview:
[Sauron] was taken in the midst of his mirth, and his seat and his temple fell into the abyss. But Sauron was not of mortal flesh, and though he was robbed now of that shape in which he had wrought so great an evil, so that he could never again appear fair to the eyes of Men, yet his spirit arose out of the deep and passed as a shadow and a black wind over the sea, and came back to Middle-earth and to Mordor that was his home. There he took up again his great Ring in Barad-dûr, and dwelt there, dark and silent, until he wrought himself a new guise, an image of malice and hatred made visible; and the Eye of Sauron the Terrible few could endure.
The Silmarillion, Akallabêth
Sauron... fled back to Middle-earth, a spirit of hatred borne upon the dark wind. He was unable ever again to assume a form that seemed fair to men, but became black and hideous, and his power thereafter was through terror alone. He re-entered Mordor, and hid there for a time in silence. But his anger was great when he learned that Elendil whom be most hated, had escaped him, and was now ordering a realm upon his borders.
Therefore, after a time he made war upon the Exiles, before they should take root.
