The U.E. stands for Universe Eraser. U.E. is commonly used as the common name so rival empires will not know its real name. It was a super weapon developed by the Hunre Empire to destroy all of the Universe, but the warlord actions of The Mrox Empire stopped this by near-obliterating the world that was storing it. Another one was built but could only destroy a small part of a galaxy. It was for the first time in Galactic Empires it destroyed The Hunre Empire and The Karnasaur Empire.
