Rivendell was founded in the Second Age after the dark lord Sauron's destruction of the Elvish land of Eregion. Rivendell remained as the only Elven settlement in eastern Eriador; Gil-galad gave Elrond the Ring Vilya, providing him with the power to protect Rivendell and slow the passage of time in its hidden valley: indeed, Rivendell kept its own calendar. Rivendell survived repeated attacks in the Third Age by the armies of the Witch-king of Angmar. Rivendell held the heirlooms of the Rangers of the North from the lost kingdom of Arnor, including the shards of Elendil's sword Narsil, the Sceptre of Annúminas, and the Star of Elendil. Elrond fostered the children of the heirs to Arnor's throne, the last being Aragorn. While in Rivendell, Aragorn met and fell in love with Elrond's daughter, Arwen. They were married after he was crowned king of both Gondor and Arnor. Sauron's enemies including Elrond formed the White Council, which met in Rivendell, as when the Council decided to eject the Necromancer from his fortress in Dol Guldur. The protagonists of The Hobbit take advice from Elrond in Rivendell. The protagonists of The Lord of the Rings meet in Rivendell, attend the Council of Elrond, and decide on the quest to destroy the One Ring. The hero Aragorn's sword is reforged as Andúril by Rivendell's smiths. When the One Ring is destroyed, Elrond's ring loses its power, and he leaves to sail for Valinor.
