Elrond

Elrond is the ruler of Rivendell and a supporting character in Lord of the Rings and The Hobbit. He is a Half Elf from Beleriand.

After the Sons of Feanor destroyed Beleriand, Elrond was moved to Lindon along with his brother. Like all half-elves, he is given a choice to be immortal or living among men. Elrond chose to live among his brethren and become immortal unlike his brother Elros. Gil-galad recruited Elrond as his herald during the Second Age. Gil-galad and Elrond were attacked by Sauron and his forces. Elven reinforcements arrive to drive the Dark Lord's army into Moria. Elrond retreated to a valley that he established a settlement that would later be called Rivendell.

Elrond was later a commander of the Last Alliance between Men and Elves. Gil-galad and Elendil led the Alliance into Barad-dur. Sauron was defeated in the battle but Elendil and Gil-galad were killed as well. Elrond got married in the beginning of the Third Age and had a daughter named Arwen. During the Third Age, he was a major ally of Arnor in their battle against the Witch-King. Despite the kingdom's fall, Elrond drove the Witch-King's armies back and help hide the remnants of Dunedain.
