Marhari, descendant of Vidumarh was the leader of a Northman army in the Battle of the Plains (T.A. 1856), where he was slain by Wainriders. A Warrior of the Éothraim of Rhovanion, and the Prince (Rh. "Hauhthiu") of the Gadraughts tribe, he was the most influential Horse-lord of his day. His son, Marhwini, led the Northman refugees out of eastern Rhovanion and into the Vales of the Anduin.
