The Sea of Helcar (also spelt Helkar) was a great inland sea existing during the First Age. In the beginning of Arda, the Valar created the Two Lamps. Due to Melkor's deceit these were destroyed, and where Helcar, the northern Lamp stood a great inland sea was formed, which was named the Sea of Helcar after the tower on which the northern lamp had stood. The Awakening of the Elves was at Cuiviénen, a gulf in the Sea of Helcar, and during the Great Journey they passed to the north of it through Wilderland on their way to Beleriand.
