They came back from the stars and found their world had gone. No cities, no roads, no ships, nothing except a planet covered in vast forests and oceans teeming with life - but not human life.Thousands of years had passed unknown to them.

They learn how they can begin again - but the price is heavy. The earth is still rich but we cannot make the same mistakes again.
