The Main Energy Controller is, as the name indicates, the main energy controller that maintains the planet Aether. The device, guarded by U-Mos, contains a portion of the light of Aether, a form of energy responsible for keeping the planet stable and habitable. This machine receives and regulates the light beams broadcast from the other three sectors of Aether, and serves as a central nexus for the planetary energy supply and light-based teleportation system.
