Rían, wife of Huor, dwelt with the people of the house of Hador; but when rumour came to Dor-lómin of the Nirnaeth Arnoediad [the Battle of Unnumbered Tears], and yet she could hear no news of her lord, she became distraught and wandered forth into the wild alone. There she would have perished, but the Grey-elves came to her aid. For there was a dwelling of this people in the mountains westward of Lake Mithrim; and thither they led her, and she was there delivered of a son before the end of the Year of Lamentation.
