After the despatch of the Nine Valar for the governance of the world Morgoth (Demon of Dark) rebels against the overlordship of Manwë, overthrows the lamps set up to illumine the world, and floods the isle of Almaren where the Valar (or Gods) dwelt. He fortifies a palace of dungeons in the North. The Valar remove to the uttermost West, bordered by the Outer Seas and the final Wall, and eastward by the towering Mountains of Valinor which the Gods built.
