Eneadurians

The Men of Eneadur are a lonely people on the Belegaer or western sea.They are the inhabitants of a forsaken Island close to the archipelagos known as Enchanted Isles, Twilit Isles and Magic Isles.

They are rarely visited by passing elven ships and are isolated from other mortals.

speculations
The Eneadurians are most likely survivors of the Númenoreans who explorred the western oceans before the cataclysm, or after the cataclysm when Explorers of the Dúnedain and Black númenóreans tried to find remnants of Númenór as the legendary Isle of Meneltarma.
