The Earth Nations are a council of five major human powers that originate from and maintain territories on earth and have expanded to inhabit many galaxies and star systems. The council is made up of different empires, but they try to maintain close relations and advance the cause of humanity against that of its enemies in the universe. It is the only international union between nations of the same species, making it unique and giving it a somewhat larger voice at the Universal Federation. They share a very large administrative district centered around the Sol System and a federal colony on Ceres, which helps to avoid conflicts and issues among themselves.
