Celtaya is a large dessert former tropical forest that resides somewhere in the Red Line. It is largely desertic now and scattered with ruins of the former Celtaya Civilization, that lived in the region. The large city of the Celtaya Civilization still stands today as a small remain of the formerly great civilization, but because of the formerly cave dwelling Sanshu the entire region has become a dessert that regularly turns into tropical jungle, back and forth all year long.
