Elrond is Lord of Rivendell, the scenic “valley of the elves” that plays an important role in both The Hobbit and The Lord of the Rings.
He is one of the “great” figures of Middle Earth, those of the mighty Elves of old that yet dwell in Middle Earth.
He is also the keeper of Vilya, one of the Three Rings of the Elves, which he was given by Gil-galad.
We discover, through the indices included with The Lord of the Rings – and more specifically through The Silmarillion – that he is the son of Earendil and Elwing, two momentous figures in the history of Middle Earth. He is also the great grandson of Beren and Luthien, who comprise another of the central tales of Tolkien’s mythology. He has, one might say, an impeccable pedigree.
His nickname “half-elven” is not entirely accurate. His father was “half-elven” – offspring of the elven Idril and the human Tuor – and his mother was an elf with some remnants of human and Maiar ancestry (granddaughter of Beren and Luthien).
He and his brother Elros were granted by the Valar the ability to choose their race, either human or elvish. Elrond chose that of the elves, Elros that of men. Elros went on to found the line of the kings of Numenor.
Elrond, being an elf and therefore immortal, at the time of the events which take place in The Lord of the Rings is more than 6000 years old.
He is represented as tall – in the manner of the Elf Lords of old – wise, noble, and good. His appearance is of an ageless countenance, fair skinned, grey-eyed, dark-haired. His description bears a marked resemblance to that of King Thingol, his great-great-grandfather and King of the elves of Doriath in times long past.
Elrond was portrayed by Hugo Weaving (see above picture) in the Lord of the Rings movie trilogy directed by Peter Jackson.
