The Emotional Electromagnetic Spectrum is an energy field that is fueled by the emotions of all sentient beings. Inadvertently, sentient beings channeled and created seven unique forms of energy based on their emotions, with a certain color unique to the emotion. The Maltusians, the oldest known race in existence, were the first to discover and harness this field. Krona was known to have once wielded the entire power of the Emotional Spectrum for a moment though it was believed since he was an immortal he was capable of such a feat. The successor races eventually chose to harness the emotions of several different colors. They also discovered that the farther one is away from the center of The Spectrum, the more control the energy has on the wielder. According to a prophecy in the Book of Oa, the seven colors of the emotional spectrum would be harnessed by seven different Lantern Corps, which would go to war with each other in a conflict called the War of Light and fulfilling The Blackest Night Prophecy.
