Dior
Dior, also known as Dior Eluchîl, was the son of Beren Erchamion of the House of Bëor and the princess Lúthien Tinúviel, daughter of King Thingol and Melian.
Dior, also known as Dior Eluchîl, was the son of Beren Erchamion of the House of Bëor and the princess Lúthien Tinúviel, daughter of King Thingol and Melian. He later became the second (and last) King of Doriath as the only heir of Thingol, and thereby the High King of the Sindar also. Dior was called the Fair and was the first Half-elf in Middle-earth's history, for his father was of the race of Men, and his mother inherited Elven blood.
Biography
Dior was born in the First Age on Tol Galen in East Beleriand. He later moved to Lanthir Lamath, where he married princess Nimloth of Doriath. Nimloth was the daughter of prince Galathil of Doriath, who was the brother of Celeborn. Dior and Nimloth had three children: two sons, Eluréd and Elurín, and one daughter named Elwing.
After Thingol was slain by the Dwarves who coveted the Nauglamír, Dior became King of Doriath as Thingol's only heir apparent. In Doriath, King Dior and his wife Queen Nimloth lived peacefully for three years until the Sons of Fëanor learned he inherited the Silmaril that was previously kept by his parents. After Dior rejected their claim to the Silmaril, the Sons of Fëanor declared war on Doriath.
He and Nimloth were slain in the Sack of Menegroth, as were Celegorm, Curufin, and Caranthir. In revenge, the servants of Celegorm captured Eluréd and Elurín, and abandoned the young children to die in the woods of Doriath. Elwing, however, escaped with the Silmaril and a remnant of the Elves of Doriath to the Havens of Sirion, where she wedded Eärendil the Mariner, and they together sought pardon and aid from the Valar.
Dior was one of the fairest beings to ever live, a product of three different heritages (races): Ainur (Maiar), Men, and Elves. His paternal grandparents were Barahir (a great chieftain of the Edain) and Emeldir the Man-hearted. His maternal grandparents were King Thingol and Melian the Maia.
Etymology
Dior probably means "successor". He was also called Eluchíl which means "Heir of Elu", Ausir which means "the Wealthy", and Aranel which means "Noble Elf" or "King of Elves".
