Long ago, Aether was in danger of being destroyed in the near future due to its supply of planetary energy having reached a critical stage. The peaceful Luminoth prevented this energy from expiring by constructing a Main Energy Controller and three sub-controllers that would collect, regulate, preserve and radiate the planetary energy all across Aether through a global network. Since then, the Light of Aether is used by the Luminoth to stabilize the planet, sustain their settlements and power their technology in Agon, Torvus, and Sanctuary.
