Hail Columbia: The Second Renaissance

God proclaimed that one day the world would end in chaos in the Book of Revelation. And that day came. As the world crumbled in the ashes of the apocalypse, the United States of America somehow miraculously survived. When the dust settled, the now sole surviving country of the Old World re-established the rule of law in its land, taking forth toward the stars, discovering new worlds, and took in many survivors of the apocalypse. As new continents rose across the Earth, four kingdoms were established. Kingdoms that forgot about the Old World. Now alone with new worlds, species, and allies, the US is left a choice: remain isolated or reveal themselves to the outside world?
