Legolas Greenleaf was a Sindarin Elf who became a part of the Fellowship of the Ring. With his keen eyesight, sensitive hearing, and excellent bowmanship, Legolas was a valuable resource to the other eight members of the Fellowship.
Legolas was Prince of Mirkwood, the son of King Thranduil, descendants from the royal line of Sindarin elves. Legolas was considered young by Elven standards, but was at least five centuries old. He first came to prominence at the council of Elrond, where he came as a messenger from his father to discuss the escape of Gollum. Elrond picked Legolas to become one of the members of the Fellowship that set out to destroy the One Ring.
