The Republic of Castlenburg is a massive, genial nation, ruled by Professor Koutaless Jumbalya Maxwell with an even hand, and notable for its avant-garde cinema, punitive income tax rates, and stringent health and safety legislation. The compassionate, democratic population of 2.505 billion Castlenburgers enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The large, socially-minded government prioritizes Education, with Administration, Environment, and Healthcare also on the agenda. It meets to discuss matters of state in the capital city of Castlice. The average income tax rate is 68.3%, and even higher for the wealthy.

The Castlenburgan economy, worth 178 trillion Prosperas a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Tourism industry, with major contributions from Information Technology, Book Publishing, and Cheese Exports. Average income is 71,431 Prosperas, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

School plays were recently banned due to concerns of child endangerment, commuters are denied boarding for attempting to bring packed lunches onto trains, Castlenburg's soft-touch approach to diplomacy has made it known as the 'push-over' of the region, and incarcerated crime lords manage their empires from massage tables. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Castlenburg's national animal is the Owl, which is also the nation's favorite main course, and its national religion is Protestantism.

Castlenburg is ranked 108,251^st in the world and 573^rd in Europe for Largest Cheese Export Sector, scoring 2,324.76 on the Mozzarella Productivity Index.
