Creation Energy is a type of energy system that was discovered in the second half of the 4th century SD on Milokeenia. It didn't achieve any practical use until the first half of the 8th Century. The premise of Creation Energy is that energy in the imaginary number space can now be tapped for use in three-dimensional space. This results, in theory, an infinite amount of energy that can be produced. Engines and cannons using Creation Energy were developed by the Pangalactic Federation.
