From the initial exploration of the solar system in the "Era of Enlightenment", to the iron-blooded expansion of the "Glory Expedition", to the transformation of the planet and the confrontation between civilizations in the "Age of Sinking", the Human Federation has spent three thousand years carving the bloody mark of "extreme humanism" on the Milky Way - today, the Federation's starships shuttle between the transformed colonial planets, the slogan "Humanity First" is painted on the bulkhead of every space station, and the surveillance signals of the Galactic Convention Alliance are lingering around the borders of the Federation like ghosts.
