Elrond is a half-elven. Both of his parents, Eärendil and Elwing, were half-elven, having both Men and Elves as ancestors. He is the bearer of the elven-ring Vilya, the Ring of Air, and master of Rivendell, where he has lived for thousands of years through the Second and Third Ages of Middle-earth. He was the Elf-king Gil-galad's herald at the end of the Second Age, saw Gil-galad and king Elendil fight the dark lord Sauron for the One Ring, and Elendil's son Isildur take it rather than destroy it.
