Lenwë

The leader of the Elves from the host of Teleri who refused to cross the Misty Mountains on the westward journey from Cuiviénen (the Nandor). Father of Denethor.

He forsook the westward march, and led away a numerous people, southwards down the great river, and they passed out of the knowledge of their kin until long years were past. -- The Silmarillion
