Lake Helevorn, by Ted Nasmith

Lake Helevorn surrounded by the Blue Mountains, as depicted by Ted Nasmith

Lake Helevorn was a deep, dark lake in Thargelion just south of Mount Rerir in the northeastern Beleriand.[1]

According to The Atlas of Middle-earth, it appeared to span around twenty miles from its west to east shoreline.[2]


After the return of the Ñoldor to Middle-earth, Caranthir, the fourth son of Fëanor, took up residence along Lake Helevorn's shorelines.[3] During the Dagor Bragollach, Glaurung the dragon polluted and defiled its waters. The lake, along with Caranthir's domain, was destroyed at the conclusion of the War of Wrath.[4]


Helevorn is a Sindarin word meaning 'Black-Glass'.[5]
