No one in the Ark thought that people who lived on the surface would survive long enough since the world fought against the machines called, Raptures. It has been decades since the Rapture war, and there never is a calling of another human from the surface ever again. The Nikkes, female war-machines that fight against the Raptures, and Commanders are in question to a certain individual. Not the Pilgrims, wandering Nikkes, but a wandering human. The ARK said that the chance of surviving on the surface is below one percent. Whoever this person is, might be below the one percent.
