Elrond Peredhel, or Elrond Half-elven, is a fictional character in J. R. R. Tolkien's Middle-earth world, appearing in The Lord of the Rings and other works.
Elrond is one of the Half-elven, son of Eärendil and Elwing, born at the end of the First Age of the Sun. He chose a life as an Elf, whereas his brother Elros chose life as a mortal Man. Elrond founded the Elven settlement Rivendell in the Second Age, and became its Lord and Master. He fought in the War of the Last Alliance under the command of Gil-galad, who gave him the Ring Vilya for safekeeping. Elrond married Galadriel's daughter Celebrían at the beginning of the Third Age, with whom he fathered the twin sons Elladan and Elrohir, and the daughter Arwen.
Toward the end of the Third Age, he became foster-father to Aragorn. Aragorn later fell in love with, and many years later was betrothed to, Elrond's daughter Arwen. Elrond presided over the Council which decided the fate of the One Ring, and chose the Fellowship of the Ring to accompany Frodo Baggins on his quest to Mount Doom. At the end of the Third Age, Elrond left Middle-earth for Valinor.
