In the aftermath of the Leviathan Seed's collision with Aether, the Luminoth first discovered the Ing when they began to possess local creatures. With their enemy revealed, the Luminoth created portals to travel to Dark Aether, where volunteer scouts discovered their enemies and that their missing planetary energy was housed in the Sky Temple, only to find the atmosphere of Dark Aether too toxic to survive for long. With that, the Luminoth built Light Crystals and Light Beacons in order for their warriors to travel to Dark Aether in order to explore Dark Aether and battle the Ing.
