Arwen

Arwen Undómiel, often called Arwen Evenstar, was the Half-Elven, half-human daughter of Lord Elrond and his wife, Celebrían, granddaughter of Galadriel and Celeborn, and the sister of Elladon and Elrohir. Arwen was also the love of Aragorn's life. She rescued Frodo  by taking him to Rivendell to be healed by her father. She later gave Aragorn her Elven necklace to remember her by. Arwen later was sent to go to the Grey Havens, but she stayed behind as she saw a vision of her son. The future may have fallen because Arwen's health started to decline because the ring was still in effect. After the Ring was destroyed, Arwen returned to her normal self and went to Gondor where she reunited and married Aragorn. They had a son named Eldarion and several daughters.
