Location from enders-game by Orson Scott Card
Humanity's homeworld — scarred by Formic invasions, united by the Hegemony, torn apart by post-war politics, and the planet Ender could never return to.
Earth in the Enderverse is defined by what happens after the Formics are gone. The existential threat that united humanity disappears, and immediately the old conflicts resume — intensified by Battle School graduates who are now the most capable military commanders on the planet. Alai unifies the Muslim nations. Han Tzu leads China. Virlomi leads India. Bean and Peter play chess with continents. Ender can never go back. His xenocide made him either a hero or a monster depending on who you ask, and both designations make Earth unsafe for a boy who just wants to be left alone. He leaves with Valentine. He doesn't return for 3,000 years.
A blue-white marble viewed from Battle School's viewport. ~12 billion people. The political landscape shifted from unified resistance against the Formics to factional warfare the moment the alien threat disappeared.
