Rivendell, or Imladris, is an Elven outpost in the Misty Mountains on the eastern edge of Eriador. It was established by Elrond in S.A. 1697 as a refuge from Sauron after the Fall of Eregion. It remained Elrond's seat throughout the remainder of the Second Age and through the entirety of the Third Age. Rivendell had a strong alliance with the Kings of Arnor, and after the fall of Arthedain, it became a refuge for the Rangers of the North and the Heir of Isildur.
