Elladan and Elrohir were the twin sons of Elrond the Half-elven and Celebrían of Rivendell, and were noted for their close friendship and cooperation with the Dúnedain of the North, Rangers of the North, and Men in general, and for their deeds during the War of the Ring.
In TA 2509, the brothers rescued their mother from her imprisonment with the Orcs. Although she was physically healed by Elrond, after fear and torment from the Orcs she lost all joy in Middle-earth, and so she departed for the Grey Havens the next year. Due to this, the twins harbored great hatred for Orcs.
By the year TA 2933, Elladan and Elrohir went riding against Orcs with Arathorn II, the father of Aragorn. There Arathorn was slain and his wife and son went to dwell in Imladris, where Elrond received Aragorn as his foster-son, naming him "Estel".
