The Republic of Castiana 16 is a huge, environmentally stunning nation, remarkable for its irreverence towards religion. The hard-nosed population of 328 million Castiana 16ians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government juggles the competing demands of Law & Order, Defense, and Healthcare. The average income tax rate is 24.2%, but much higher for the wealthy.

The sizeable but inefficient Castiana 16ian economy, worth 11.9 trillion New Dollars a year, is fairly diversified and led by the Tourism industry, with significant contributions from Information Technology, Furniture Restoration, and Cheese Exports. State-owned companies are common. Average income is 36,294 New Dollars, and evenly distributed, with the richest citizens earning only 2.2 times as much as the poorest.

Crime is well under control, thanks to a capable police force and progressive social policies in education and welfare. Castiana 16's national animal is the Wild Bunny, which frolics freely in the nation's many lush forests.

Castiana 16 is ranked 237,697^th in the world and 4,945^th in the Rejected Realms for Largest Populations, with 328 million capita.
