GalleryImages of Dior

He appeared as the fairest of all the children of the world, of threefold race: of the Edain, and of the Eldar, and of the Maiar of the Blessed Realm.

Dior was the son of Beren and Lúthien, and the grandson and heir to the throne of Elu Thingol, King of Doriath. Dior was the first of the Peredhil.[2][3]


Dior was born on the island of Tol Galen in East Beleriand.[4] When he was 27, he married Nimloth of Doriath,[note 1] 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 with his father and a host of Green-elves of Ossiriand journeyed swiftly north to the river Ascar and fought the Dwarves of Nogrod in the Battle of Sarn Athrad.[5]

In F.A. 503, he and his family went to Menegroth and restored the realm of Doriath. After the death of his parents, a lord of the Laiquendi came to Doriath bringing the Nauglamír, which was worn by his mother. After mourning, he decided to wear it himself. When he placed the Nauglamír on himself, it sat lightly and he appeared as the fairest of three living races: Maiar, Elves, and Men. This news came to the Sons of Fëanor, who came to Doriath with their followers, consumed by the Oath of Fëanor.[5]

Dior managed to kill Celegorm, and Caranthir and Curufin were also slain, but the kingdom of Doriath was destroyed. Dior and Nimloth were slain during the Second Kinslaying, along with anyone trying to prevent the Sons of Fëanor from gaining the Silmaril.[5]

After the attack, the servants of Celegorm left Eluréd and Elurín in the forest to die. Elwing, however, carrying the Nauglamír, escaped with the remnant of the Elves of Doriath to the Havens of Sirion.[5] Years later, she would wed Eärendil and together they would seek aid from Valinor.[6]


In the Etymologies, the name Dior is said to mean "successor" in Doriathrin. The name derives from Primitive Quendian ndeuro ("follower, successor"), from root NDEW.[7]

Other names

Dior was first called Aranel,[4] probably Sindarin for ("Elf King"). [8] Later he was called Eluchíl ("Heir of Elu") and the Fair.[4]

The Book of Lost Tales

In The Book of Lost Tales, a name of Dior was Ausir (Gn. "The Wealthy").[9][10]

Dior's Fate

In an older version of the Quenta Silmarillion, Manwë spoke this judgment to Eärendil:

To Eärendel I remit the ban, and the peril that he took upon himself out of love for the Two Kindreds shall not fall on him; neither shall it fall upon Elwing who entered into peril for love of Eärendel: save only in this: they shall not ever walk again among Elves or Men in the Outer Lands. Now all those who have the blood of mortal Men, in whatever part, great or small, are mortal, unless other doom be granted to them; but in this matter the power of doom is given to me.

Christopher Tolkien interprets it as that Dior would inherit his father's mortality, irrespective of his mother's nature and choice:[11]

§9 It is to be observed that according to the judgement of Manwë Dior Thingol’s Heir, son of Beren, was mortal irrespective of the choice of his mother.


  1. Nimloth's parentage is uncertain. She may have been the daughter of Galathil, grandson of Elmo, younger brother of Elu Thingol. This would make Nimloth and Dior second cousins once removed.
