The Dominion of River of September is a massive, safe nation, ruled by Emperor Arthur with an even hand, and renowned for its museums and concert halls, smutty television, and pith helmet sales. The compassionate, hard-working, democratic population of 3.635 billion Jubatians enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized, liberal government juggles the competing demands of Defense, Industry, and Administration. It meets to discuss matters of state in the capital city of Eldória. The average income tax rate is 90.3%, and even higher for the wealthy.

The frighteningly efficient Jubatian economy, worth 646 trillion pilas a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Tourism, Arms Manufacturing, and Book Publishing. Average income is an impressive 177,856 pilas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Inter-species marriages are ignored by the government, television executives are interested in turning Emperor Arthur's zany home life into a sitcom, the Museum of Blackacrean War Crimes is located on "Blackacre Did Nothing Wrong Avenue", and all Jubatians live like kings. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. River of September's national animal is the Pardian leopard, which frolics freely in the nation's many lush forests, and its national religion is alfarism.

River of September is ranked 285,705^th in the world and 9^th in Imperial Federation for Most Primitive, scoring -446.52 on the Scary Big Number Scale.
