Energy Controller

The Energy Controllers are devices created by the Luminoth during their Golden Age on Aether. Their main purpose is to regulate energy-related phenomena (such as weather) on the unstable planet. There are 4 Energy Controllers on Aether, each stored within the depths of a Luminoth Temple. Energy Controllers have a reservoir of stored energy above the control unit, which appears as a large sphere of light. 3 of the Energy Controllers in the lesser Luminoth Temples direct a portion of this energy to the Controller in the Great Temple.

When a Phazon-bearing asteroid crashed into the planet, creating Dark Aether, the energy was split between the two worlds, and both became unstable. During the war between the Luminoth and the Ing, most of it was stolen by the Ing in an attempt to destroy Aether. However, when Samus became bonded with the Energy Transfer Module, she successfully returned all the energy to Aether, resulting in the dark planet's destruction.
