Humanity, a tiny race born in the solar system. Carrying the seeds of hatred, Fang Yuan descended upon the Wandering Earth. Using this as a hub, he connected countless civilizations and protected Earth's civilization. Since then, led by Holy Terra, humanity has journeyed across the myriad realms, conquering the heavens. When the banners of the Star Legions soared across the universe. When power armor crushed the skulls of omnics. When the Iron Titans awed countless alien races. Dignity lies only on the edge of a chainsaw, truth within the range of a blaster. ............
