Elladan and Elrohir are twin brothers, so alike that many cannot tell them apart. They are the sons of Elrond, born early in the Third Age and are therefore nearly three thousand years old.
Elladan's name means "Elf-Man" – a fitting name, for he and his brother are descended both of Elves and Men. As Peredhil, or Halfelven, these twin brothers could choose to remain on Middle-earth as a mortals or cross the sea to the Undying Lands as Elves.
The brothers are skilled hunters and trackers who have ranged far across the lands of Middle-earth, often alongside the Rangers. They have a close friendship with Aragorn and often travel with him. They have been sent by Elrond to assist those who might help hold Agandaûr and his forces at bay.
