The #pitch was: Sometime in the #farfuture, five #Starsystems were #colonized by #JapaneseNationalists; people who #Romanticized #Shogunate #Japan and were swept up in a movement to reclaim their perceived golden age.
Flash forward an unspecified amount of time, and the five systems are unified into a #hightech shogunate. Each system is ruled by a #Daimyo, who answered to the #Shogun of the #Fuji system.
At least they used to, until just before the game starts, when Fuji's Star went #Novae.
