Also known as: Curufinwe, Spirit Of Fire
Feanor -- Curufinwe, the Spirit of Fire -- was the eldest son of Finwe, first High King of the Noldor, and of Miriel Serinde, who spent her life-strength in his bearing and afterward died. Mightiest in skill of hand and mind of all the Children of Iluvatar, he wrought the Tengwar letters, devised the palantiri, and in his greatest work captured the light of the Two Trees of Valinor in the three Silmarils -- jewels so hallowed and so fair that not even the Valar could remake them. But his spirit burned as hot in pride and possessiveness as in genius, and the lies of Melkor poured poison between him and his half-brothers.
When Melkor slew Finwe and stole the Silmarils, Feanor named him Morgoth, the Black Foe of the World, and swore with his seven sons a dreadful and unbreakable Oath: to pursue with vengeance any -- Vala, Elf, or Man -- who should withhold a Silmaril from them. That Oath drew the Noldor into rebellion against the Valar and to the first Kinslaying at Alqualonde, where they shed the blood of their Telerin kin to seize their white ships. Feanor led his people back to Middle-earth in defiance and burned the ships at Losgar; but in the first battle thereafter, pressing recklessly ahead of his host, he was surrounded by Balrogs and dealt his death-wound by Gothmog, and his fiery spirit consumed his body to ash as he died within sight of Thangorodrim. His Oath outlived him, and drove his sons to ruin and atrocity through all the long Wars of the Jewels.
