fleeing from the north she went down into
Beleriand, and dwelt beneath Ered
Gorgoroth, in that dark valley that was after called
Nan Dungortheb, the Valley of Dreadful Death, because of the horror that she bred there. For other foul
creatures of spider form had dwelt there since the days of the delving of
Angband, and she mated with them, and devoured them; and even after
Ungoliant herself departed, and went whither she would into the forgotten south of the world, her offspring abode there and wove their hideous webs. Of the fate of Ungoliant no tale tells. Yet some have said that she ended long ago, when in her uttermost famine she devoured herself at last.
