Nehemoth

“Therefore in the autumn of the Year of Lamentation Morwen sent Túrin forth over the mountains with two aged servants, bidding them find entry, if they could, into the kingdom of Doriath. Thus was the fate of Túrin woven, which is full told in that lay that is called Narn i Hîn Húrin, the Tale of the Children of Húrin, and is the longest of all the lays that speak of those days. Here that tale is told in brief, for it is woven with the fate of the Silmarils and of the Elves; and it is called the Tale of Grief, for it is sorrowful, and in it are revealed most evil works of Morgoth Bauglir.”
