In Terra's land, natural disasters of unknown origin have been happening in various regions at irregular intervals. As a result, many individuals migrated to mobile cities that were developed over time to avoid these calamities. The Originium left behind by such catastrophes has accelerated the growth of civilization due to its immense energy. However, it also brought an illness called Oripathy with it, which is incurable and causes the bodies of those affected to gradually crystallize and become a new source of infection at death. In many countries, people with Oripathy are subjected to persecution under regimes of segregation and forced labor. Those who were oppressed by governments are beginning to rebel. Rhodes Island, a pharmaceutical company researching a cure for Oripathy, is taking up arms and launching a conquest in an attempt to save all those affected from the disease.
