This Cold War was a series of small-scale confontations and proxy wars between the Confederate Systems and the Ashellian Empire, mainly fought along their mutual border. The Cold War began after the Bration War repulsed an attempted Ashellian invasion of the region and continued for the next three hundred years until 2015 when the Empire attacked the world of Natal Prime pushing the Confederate Systems to join the Ashellian War on the side of Colonia.
