Maglor's Gap was guarded against the forces of Morgoth in the early First Age by Maglor, second son of Fëanor. During the Dagor Bragollach (Battle of Sudden Flame), they were defeated; Maglor fled to Himring, along with most survivors of the battle in that region. After the War of Wrath, Maglor's Gap was destroyed and was lost under the waves along with the rest of the Beleriand.
