The Desian Human Ranches are places where humans get Exspheres implanted in them in order for the exspheres to become more powerful. This cause the host to grow weak and maybe even turn into a monster. The humans are kept in cages within the ranch and are treated like prisoners in a jail. When they are let out of their cells they are forced to do labor or will face punishment. Each human ranch is controlled by a Desian Cardinal who oversees the production of exspheres. In the quest for world regeneration, Refill Sage makes all of the ranches they go to self-destruct when they have saved all the humans and killed the Desian Cardinal.
