This province contains Ryoko Owari Toshi, perhaps the most famous city in the Empire after the capital itself. The roads of the province are busy with travelers coming to and from the city, while the fields are given over almost entirely to the cultivation of opium. Ryoko province supplies almost three quarters of the Empire’s medicinal opium, and most of the outlying villages center around its production and processing.
