Tuor was a great hero of the Third House of Men, the only son of Huor and Rían. When his father died in the Nirnaeth Arnoediad, Tuor was first fostered by Elves, then captured by Easterlings. He later escaped and lived the life of an outlaw. He was ordered by the Vala Ulmo to go to Gondolin, in order to warn the King Turgon. He then remained in Gondolin and married Turgon's daughter, the Elf Idril. This was the second union between an Elf and a Man. Their only child was Eärendil the mariner. Tuor sailed eventually to the West with Idril, and it was a tradition under the Eldar and Edain that he alone of Men was counted as Elven kindred.
