A long time ago, satellite cities such as City Hell were supposed to provide the industrial support and slave labor to keep the mother cities like Heaven functioning. They were a home to the underprivileged, the sick, the dying, and anyone else that might be a threat to the new way of life. Eventually, the mother cities became self-sufficient and no longer needed their workers, who began to dream of making it big and somehow getting into the good life. Even in Hell, people had dreams and sometimes, when someone bigger would mess with their lives, they needed someone to help them. That’s when they call Mosaic.
