In the metal city of Shosa the people live of Viko, a source of power that comes from the planet. They use it for their army, for their power, for their buildings. It seems to be a wonderful exchange. The planet supplies for them and they can live. Most people are naive or turn a blind eye to the true matter of the situation. Viko is the source of all life, and they are draining it from the planet for their own personal gain.
