Also known as: Tinuviel, Nightingale
Luthien Tinuviel, daughter of King Thingol of Doriath and Melian the Maia, was the fairest of all the Children of Iluvatar that ever were or shall be, and in her the beauty of the Eldar was joined to the grace of the divine. In the woods of Neldoreth she met and loved the mortal man Beren son of Barahir; and when her father set Beren the impossible bride-price of a Silmaril from Morgoth's crown, Luthien would not be left behind. Imprisoned by Thingol to keep her from the quest, she wove a cloak of shadow and her own grown hair, escaped, and went to find her love.
Her power was greater than any sword or army of that age. She cast down Sauron and broke his tower of Tol-in-Gaurhoth to free Beren from its pits; and she walked into the deeps of Angband itself and laid Morgoth and all his court asleep with her enchanted song, so that Beren cut a Silmaril from the Iron Crown. When Beren was slain in the hunting of the wolf Carcharoth, Luthien's own spirit failed and went to the Halls of Mandos; and there she sang before the Doomsman a song of such interwoven beauty and sorrow that he was moved to pity for the only time in the history of the world. She was granted a choice without precedent -- to dwell deathless in Valinor without Beren, or to become mortal and share his fate -- and she chose mortality. So she and Beren returned to life and dwelt a while upon the green isle of Tol Galen; and through their son Dior her blood passed to Elwing, to Earendil, and so to Elrond and Elros, and down to Arwen and Aragorn, mingling the kindreds for ever.
