Prologue: 
In the year 2036 an asteroid collides with the moon. The moon was destroyed. The lunar dust rained down on the earth for years blocking out the sun and contaminating the oceans. The earth is now uninhabitable and squalid. 
The richest and smartest people on the planet knew about the asteroid 20 years in advance. They started building a space station the size of the moon to live on. Three other space stations were built too. The Russians also build a space station on the Moon Europa orbiting Jupiter. The military lived on a barrack on the red planet Mars. The last space station housed the humans and e-humans, located at the edge of the solar system.
