Sons of Fëanor
- Maedhros the Tall, who ruled over the "March of Maedhros", from his base on the hill of Himring
- Maglor the Mighty Singer, who ruled over Maglor's Gap
- Celegorm the Fair, who ruled over Himlad with Curufin
- Caranthir the Dark, who ruled over Thargelion
- Curufin the Crafty, who ruled over Himlad with Celegorm
- Amrod and Amras, also known as the Hunters.
They and their father led the Noldor from Valinor to Beleriand in pursuit of Morgoth, who stole Fëanor's greatest work, the Silmarils. Since Fëanor died in an early battle, his sons were the driving force behind the ensuing wars. Their heroism was great and they were mighty leaders and foes of Morgoth, but because of the Oath of Fëanor (which they all swore) their actions were also sometimes evil.
Only one survived the First Age. Because of the nature of their Oath—that they would not permit anyone else to have the Silmarils, not even other Elves—their deaths were generally not in battle with Morgoth but rather in desperate, Oath-driven assaults on other Elves. The only three not killed in such a manner were Maedhros, who killed himself at the very end of the First Age, and Maglor, who survived only to wander despondently alone along the shores of Middle-earth, and – in The Peoples of Middle-earth – Amras, who perished at Losgar by a terrible accident. In The Silmarillion, though, Amras is killed along with Amrod when they, along with Maedhros and Maglor, attack the refugee camp near the Mouths of Sirion.
The House of Fëanor
Fëanor's only grandson, Celebrimbor, collaborated with Annatar (Sauron in disguise) to create the Rings of Power. However, the Three Rings, which were the greatest Rings except for Sauron's One, Celebrimbor forged alone in secret. But the Three were nonetheless subject to the authority of the One, which Sauron in his turn had forged alone in secret.
- "...In the morning [after the burning of the ships] the host was mustered, but of Fëanor’s seven sons only six were to be found. Then Ambarussa went pale with fear. ‘Did you not then rouse Ambarussa my brother (whom you called Ambarto)?’ he said. ‘He would not come ashore to sleep (he said) in discomfort.’ But it is thought (and no doubt Fëanor guessed this also) that it was in the mind of Ambarto to sail his ship back [afterwards] and rejoin Nerdanel; for he had been much [shocked] by the deed of his father."
