Denethor (First Age)

Denethor is a fictional character from J.R.R. Tolkien's Middle-earth. He was the son of the Nandor Elf leader Lenwë (or Dan), who lived during the Years of the Trees. Hearing of the power of Thingol, he led many of his people over the Ered Luin to Beleriand. They settled in Ossiriand, renaming it Lindon, in the east of Beleriand, and Denethor became their king. They were called the Laiquendi, or Green-elves. Some time later, Morgoth loosed an army on Beleriand. The lightly-armed Laiquendi were driven back to the great hill of Amon Ereb, where Denethor was slain. The Laiquendi became a reclusive people, seldom taking up arms, and never again naming a king.

A much later Denethor was a Steward of Gondor during the War of the Ring and is a prominent character in The Lord of the Rings.
