The year is 2172 and the world is dying. A small fraction of the Earth's former biosphere remains. The world is running out of food. During these hard times part of the human population has gone sterile. There has been massive inbreeding and genetic distortions. However, teams of scientists and military personnel tasked with finding a way to save humanity from extinction are confronted with a possible opportunity: an exoplanet near the Proxima Centauri system is discovered.

Over the course of 73 years, this discovery of the exoplanet sparks a series of probe and AI missions--all leading to the realization that a new branch of humanity has arisen on Arca-45672. Now, as the Earth's biosphere collapses, governments and military organizations scramble as they see potential salvation for their dying species in this exoplanet. But should humanity be content to merely survive?
