Ryūishi (りゅういし, lit. Dragonstone) is a powerful City-state situated in the southern reaches of the Soul Society, approximately two days away by carriage from Seireitei and the surrounding Rukongai area. While very similar culturally to Seireitei, Ryūishi is more advanced technologically, and more importantly, the standard of living is higher for all classes as typical souls are not simply relegated to outlying districts and upward mobility is a reality. Its' military is one of exceptional might, with a large emphasis put on the mastery of kidō.
