Proxima Terra

It was year 2016 when future of the planet Earth was almost destroyed because of alien invasion for our resources. They introduced them selves as Collectors of natural resources but we never met them. Human race was on the edge of extinction when they started building us three stations on which we can renew our life. New societies were created each on their own without interfering with each other. Our old habits are coming back and we're putting our societies in jeopardy.
