Sobriquet: the Dark.

A Noldorin Elf, son of Fëanor and Nerdanel, fourth-born of the Sons of Fëanor. Born in Valinor in the Years of the Trees, died in Doriath in the First Age.

Along with his father and brothers, Caranthir took the Oath of Fëanor, took part in the First Kinslaying, and arrived in Middle-earth in the stolen ships of the Teleri.

In Beleriand, he ruled the land Thargelion (also known as Dor Caranthir) west of the Blue Mountains. He is known for his harsh temper and haughtiness, and for insulting some of his half-cousins and Thingol at the Council of Mithrim. However, he also negotiated a trade agreement with Dwarves of the Blue Mountains (despite a measure of mutual resentment), and saved the people of Haleth from Orcs.

Along with his brothers, Caranthir took part in four of the great battles of Beleriand (Dagor-nuin-Giliath, Dagor Aglareb, Dagor Bragollach, Nirnaeth Arnoediad). He lost his land in the Dagor Bragollach, and joined his twin brothers Amrod and Amras in the wilderness in the South. In the Nirnaeth Arnoediad, his Easterling allies (Ulfang the Black and his sons and people) proved treacherous, and contributed to the defeat of the Noldor in the battle. Caranthir's exact residence after the defeat is unknown- he could have resided on Amon Ereb with his eldest brother Maedhros for a time, or taken refuge in the woodlands of Ossiriand.

Caranthir was killed in the assault on Doriath (Second Kinslaying) , as the Sons of Fëanor were attempting to fulfill their Oath and wrestle a Silmaril from Dior.

History of Middle-earth based information:

The Quenya version of Caranthir's mother-name -Carnistir- means 'Red Face', referring to the ruddy skin complexion inherited from his mother Nerdanel. His father-name was Morifinwë - 'Dark Finwë', referring to his dark brown hair. - Caranthir is also said to have had a wife (unnamed).

According to one account of the Second Kinslaying, Caranthir was killed by a volley of arrows along with his brother Celegorm, supposedly in year 506 of the First Age.
