War of Wrath
Between the years 545–583 the War of Wrath was fought between Morgoth and the host of the Valar. As the result of the cataclysmic destruction from the war, Beleriand sank into the sea, except for a part of Ossiriand later known as Lindon, and a few isles. The defeat of Morgoth marked the end of the First Age and the start of the Second, and most of the Noldor would return to Aman, though some like Galadriel or Celebrimbor, grandson of Fëanor, refused the pardon of the Valar and remained in Middle-earth.
