Lore, skill, but light on reason
he toiled where others knew not to tread
Following folly he followed
until beneath the stars he was dead
Feanor
Fëanor was the second High King of the Noldor, eldest and most beloved son of Finwë. He had the greatest skill of word and hand, a renowned craftsman, gem-smith, and warrior. His most famous deed was the creation of the Silmarils, but he also created the palantíri, and may also have wrought the Fëanorian lamps. (Source: The Silmarillion)
