Lenwë
In J. R. R. Tolkien's fictional universe of Middle-earth, Lenwë was a leader of a group of Elves.
Lenwë was leader of that group of the Teleri who became the Nandor, when he refused to follow the host of the Eldar over the Hithaeglir during the Great Journey and instead remained in the vale of Anduin.
Lenwë was called Dan in his own language.
His son Denethor later led a group of Nandor west to Beleriand.
