The Elves were the first and eldest of the Children of Lluvatar and are considered to be the fairest and wisest race of Arda given sapience by him. Elves do not physically age or are subject to illness, however they can be slain by violence or extreme negative emotion. The Firstborn, Elder Children of Lluvatar, were conceived by Eru alone in the third theme of Ainulindale, they are the oldest and noblest of speaking races of Middle-Earth. Elves are tall beings with long light colored hair, some have darker colored but most are lighter. At first elves sang with grace and merriment without speech but later developed speech and spoke with words. The Elves lived in the forests of Middle-Earth, eating no meats and only ate plants. The Old Forest and Fangorn were the only two that Elves weren't found in. Rivendell and Lothlorien were both mentioned and visited in The Lord of the Rings, Mirkwood, or Greenwood the Great, before it was corrupt, was also mentioned and visited in The Hobbit. These three locations were the three main houses of Elves. Elves tended to stay in the northern parts of Middle-Earth unless war called them elsewhere. After the War of the Ring, Elves left Middle-Earth to the race of Men and went to the Grey Havens, a passage way to the Undying lands, heaven pretty much. Most Elves left Middle-Earth but some stayed at the Grey Havens, no history shows how long they were there in the fourth age but most believe the rest died of grief or sailed to the Undying lands themselves.
