The Saiya-Jin are a small race and live together in several ‘large’ cities. These cities aren’t too advanced, they’d look to be a village plucked out of the Middle Ages. The insides, however, are pretty advanced technology. In every town there are at least ten gyms for the Saiya-Jin to work out. If the gyms are occupied, they can fight and train outside of the city in the large and open wastelands. There are probably three cities and several smaller settlements scattered across the Northern Hemisphere.
