Seven Cities Story: Arctic Front - S01

In 2099, Earth has tilted off its axis and starts rotating at an angle of 90% to the 20th-century equator. Three years of natural disasters follow, and when things settle down, Earth's ten billion population has died and only two million moon colonists remain. Some return to begin repopulating the world in seven new cities, and the remaining colonists on the moon fear that their former neighbors might pose a threat, so they build a ring of defensive satellites to trap them on the newly repopulated homeworld.
