They have forgotten the light of the sun and now are blindly following the New God — The Great Hand. Once every few years, The Hand comes down to the people of the Central Station and takes away the chosen newborns to the world hidden behind the gates of the Sanctuary. The Hero embarks on a dangerous journey through this hostile world to find a way to open the gates and bring his child back.
