Thor: The Dark World2013

Odin:
Long before the birth of light, there was darkness...and from that darkness came the Dark Elves. Millennia ago, the most ruthless of their kind, Malekith, sought to transform our universe back into one of eternal night. Such evil was possible through the power of the Aether, an ancient force of infinite destruction. The noble armies of Asgard, led by my father King Bor, waged a mighty war against these creatures. As the Nine Worlds converged above him, Malekith could at last unleash the Aether...but Asgard ripped the weapon from his grasp; without it, the Dark Elves fell. With the battle all but lost, Malekith sacrificed his own people in a desperate attempt to lay waste to Asgard's army. Malekith was vanquished and the Aether was no more. Or so we were led to believe.
