A Peredhil, one of the Half-elven born cFA532, son of Eärendil and Elwing, twin brother of Elros. Master of the Last Homely House at Rivendell. Sailed West over Sea TA 3021.

In The Hobbit Elrond gave sanctuary and advice to Thorin and Company. He identified the swords from the Troll-hoard, Glamdring, and Orcrist and the long knife that Bilbo later named Sting, as being made in Gondolin.

Elrond knew about runes of every sort and read the ones on Thror’s Map, including the secret Moon-letters that told how to find the keyhole in the side-door of the Lonely Mountain.

Elrond thought at that time that Moria was deserted, but warned that goblins (orcs) infested the Misty Mountains. He advised a way over the high pass.

The Hobbit was Elrond’s first published appearance, although Tolkien had been writing of him for some years. In later works he was revealed as a character of great importance. NOTE: Information from The Hobbit added by Cirdaneth

His name has been translated in several ways to give very different manners, e.g. 'Star-dome' and 'Elf of the Cave'. He belonged to both the Noldor and the Sindar branches of elves, because his father had Noldorin blood, and his mother had Sindarin.

He was born at the Havens of Sirion, and when the sons of Fëanor attacked, he and his brother were taken captive. However, Maglor took pity on them, and released them. They were found near a waterfall, with Elrond in the cave behind the falls. That is how he got the name 'Elf of the Cave'.

As both his parents were Half-elves, he was given the choice of whether he wanted to be counted with the Elves, or with Men. He chose to be with the Elves (his brother chose the race of Men). At this time he went to live in Lindon with Gil-Galad.

When Sauron invaded Eriador, Gil-Galad sent Elrond to Eregion to help. When Eregion was laid to waste, Elrond retreated into a deep valley with some of the surviving elves. Here he founded Imladris in SA 1697. Rivendell prospered partly because Gil-Galad had given him Vilya, the Ring of Air. He remained Lord of Rivendell until he passed over the Sea.

He fought with Gil-Galad and Elendil in the War of the Last Alliance in SA 3429-3441.

He was wedded to Celebrían in TA 109, but stayed in Middle-earth when she passed over the Sea in TA 2510. She bore him the twins Elladan and Elrohir in TA 130 and Arwen in TA 241.

In the Third Age he was a leader of the White Council, and he advised what was to become the Fellowship of the Ring at the Council of Elrond.

He passed over the Sea with the other Ringbearers on September 29th, TA 3021.
