They're all gone. We remember them like yesterday: pieces of our stolen heritage. Things like NASA. Football. Parades and pies. Good things, comfortable things. We remember a time when we were alone in the universe, safe and oblivious. But it's all gone now. We called them the Telestines, and in the face of their ruthless invasion we were powerless. By 2040, all the world's governments and militaries had fallen, and the remnants of humanity exiled to the solar system. We looked down on our blue planet, so close to our birthplace, so close to our home.
