The Kingdom of Chuiban was one of the two nation states on the planet Silvestria.
It was settled by the Pechili Consortium colonists, its capital being Royal City. King Bira was the monarch around 1900 PD.
An ambitious, dictatorial aristocrat from Chuiban was assisted by the People's Republic of Haven in his expansionist and aggressive war against the Canmore Republic. (HHA2.5: DLS)
