The Community of Casterbrious is a very large, cultured nation, notable for its ban on automobiles, national health service, and irreverence towards religion. The compassionate, democratic population of 360 million Casterbrions are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The government — a sprawling, bureaucracy-choked, socially-minded, outspoken morass — juggles the competing demands of Healthcare, Administration, and Education. It meets to discuss matters of state in the capital city of Arcadia. The average income tax rate is 85.7%, and even higher for the wealthy.

The sizeable but underdeveloped Casterbrion economy, worth 12.9 trillion Pandaks a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is extremely specialized, is mostly made up of the Information Technology industry, with significant contributions from Furniture Restoration. Average income is 35,869 Pandaks, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Country folk are sent to obligatory boarding schools to learn how to be civilized, getting an autograph has become harder than ever, military equipment stores have a tendency to go up in flames, and there's an aura of pseudoscience around academia. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Casterbrious's national animal is the Tafelshrew, which frolics freely in the nation's many lush forests.

Casterbrious is ranked 33,213^th in the world and 115^th in Refugia for Most Secular, with 31.14 Atheism Rate.
