The History of Middle-earth V: The Lost Road
Thus spake
Mandos in prophecy, when the Gods sat in judgement in
Valinor, and the rumour of his words was whispered among all the
Elves of the West. When the world is old and the Powers grow weary, then
Morgoth, seeing that the guard sleepeth, shall come back through the Door of Night out of the Timeless Void; and he shall destroy the Sun and Moon. But Earendel shall descend upon him as a white and searing flame and drive him from the airs. Then shall the Last Battle be gathered on the
fields of Valinor. In that day
Tulkas shall strive with Morgoth, and on his right hand shall be Fionwe, and on his left
Turin Turambar, son of
Hurin, coming from the
halls of Mandos; and the black
sword of
Turin shall deal unto Morgoth his death and final end; and so shall
the children of Hurin and all
Men be avenged.
Thereafter shall Earth be broken and re-made, and
the Silmarils shall be recovered out of Air and Earth and Sea; for Earendel shall descend and surrender that flame which he hath had in keeping. Then
Feanor shall take
the Three Jewels and bear them to
Yavanna Palurien; and she will break them and with their fire rekindle the Two
Trees, and a great light shall come forth. And the
Mountains of Valinor shall be levelled, so that the Light shall go out over all the world. In that light the Gods will grow young again, and the Elves awake and all their dead arise, and the purpose of
Iluvatar be fulfilled concerning them. But of Men in that day the prophecy of Mandos doth not speak, and no Man it names, save Turin only, and to him a place is given among the sons of the
Valar.
