House of Finarfin

In J. R. R. Tolkien’s legendarium, the House of Finwë was the royal house of the Noldor. The house was founded by Finwë, the first High King of the Noldor, who led his people from Middle-earth to the realm of Valinor within the continent of Aman in Y.T. 1105. In Valinor, he ruled in the city of Tirion. His first marriage with Míriel was short-lived: the birth of their son Fëanor left her so exhausted that she chose to leave life for the halls of Mandos. By his second wife Indis, who was of the Vanyar, Finwë had two more sons, Fingolfin and Finarfin, and two daughters, Findis and Írimë (Lalwen). Finarfin's daughter, Galadriel, is an important supporting character in The Lord of the Rings.

Early in Fëanor’s youth, he wedded Nerdanel, daughter of Mahtan, and had seven sons - the Sons of Fëanor: Maedhros, Maglor, Celegorm, Curufin, Caranthir and the twins Amras and Amrod. In Y.T. 1450 Fëanor completed his creation of the three Silmarils, which held the light from the Two Trees of Valinor. In Y.T. 1490, he was banished from Tirion for twelve years because he had threatened the life of his half-brother, Fingolfin. However, it was due to Melkor’s lies and deceits that bitterness was further sowed between the son of Míriel and the sons of Indis. Finwë followed his eldest son and his family in Formenos. They lived in Formenos for five years until news of the murder of Finwë and theft of the Silmarilli reached Fëanor. Angered, Fëanor came back to Tirion with his seven sons and spoke angry, proud words that convinced the Noldor to move into Middle-earth, far from the Valar, and claimed High Kingship. His words also led him and his sons to swear the terrible Oath of Fëanor that swore to pursue vengeance on anyone who would keep the Silmarilli from their possession. It would be this oath that would bring ruin to the House of Fëanor, and all those who were entwined.
