Dior Eluchíl (First Age 470 – 506, aged 36 years) was the son of Beren and Lúthien, and the heir to the throne of Elu Thingol, King of Doriath. Dior was one of the Half-elven. He was also called Eluchíl ("Heir of Elu"), Ausir ("The Wealthy"), and Aranel ("Noble Elf").
Dior was born on the island of Tol Galen in East Beleriand. When he was 27 he married Nimloth of Doriath1 and took her back to live by the Lanthir Lamath waterfall at the base of the Blue Mountains. There they had three children: Elwing, Eluréd, and Elurín. After Thingol was slain by the Dwarves who coveted the Nauglamír, Dior went to Menegroth and became King of Doriath.
Four years later Dior and Nimloth were themselves slain, during the Sack of Doriath by the Sons of Fëanor. The Elf lords and their servants had been consumed by the Oath of Fëanor and killed anyone preventing them from gaining the Silmaril. Dior managed to kill Celegorm, and Caranthir and Curufin were also slain, but the Kingdom of Doriath was destroyed.
After the attack, the servants of Celegorm left Eluréd and Elurín in the forest to die. Elwing, however, escaped with the remnant of the Elves of Doriath to the Havens of Sirion. Years later she would wed Eärendil the Mariner and together they would aid from Valinor.
