Caranthir
In J. R. R. Tolkien's legendarium, Caranthir (IPA: [kaˈranθir]) is a fictional character, the fourth or, in some versions, fifth of the sons of Fëanor, was also the harshest, and the quickest to anger; he was also called "Caranthir the Dark". His Quenya name was Morifinwë "The Dark Finwë", because "he was black-haired as
his grandfather". Nerdanel gave him the mother name Carnistir, which means "red face", for the reason that "he was dark (brown) haired, but had the ruddy complexion of his mother".
As the other Sons of Fëanor, Caranthir was bound by an oath to recover his father's Silmarils, which had been stolen by the Dark Lord Morgoth. This oath took the seven brothers to Middle-earth during the First Age where they established realms in exile, waged war against the armies of Morgoth, fought their own Elvish kind, and eventually brought ruin upon themselves.
Caranthir was present at Alqualondë, and also at the burning of the ships at Losgar. In the council of Noldorin princes at Mithrim after the abdication of Maedhros, he spoke out harshly against Angrod, and was rebuked by Maedhros. He had little love for his cousins, the sons of Finarfin. Caranthir accompanied his brother to East Beleriand, and build forts on the western slopes of mount Rerir. Caranthir's realm was in Thargelion, and was sometimes called Dor Caranthir (Caranthir's land); his abode was on the shores of Lake Helevorn. After the Dagor Bragollach he fled south to Amon Ereb with his brother Amras.
