Fëanor was a prince of the Noldor, the eldest son of Finwë and his first wife Míriel. He had the greatest skill of word and hand, and was a renowned craftsman, gem-smith, and warrior. Fëanor created the Silmarils, which was his most famous deed, and also wrought the palantíri and the Fëanorian lamps. In addition, he invented the widely-used Tengwar script. His passionate hatred of Morgoth and the terrible oath and his sons swore led directly to the great triumphs and tragedies of the First Age.
