The Diocese of Castres is a gargantuan, efficient nation, remarkable for its compulsory military service and complete absence of social welfare. The hard-nosed, hard-working, devout population of 13.519 billion Castresians are free to succeed or fail in life on their own merits; the successful tend to enjoy an opulent (but moralistic) lifestyle, while the failures can be seen crowding out most jails.

The relatively small, moralistic, pro-business government juggles the competing demands of Spirituality, Defense, and Administration. It meets to discuss matters of state in the capital city of Castres. Citizens pay a flat income tax of 9.0%.

The very strong Castresian economy, worth 889 trillion francs a year, is broadly diversified and led by the Book Publishing industry, with major contributions from Gambling, Furniture Restoration, and Cheese Exports. Average income is 65,799 francs, but there is a significant disparity between incomes, with the richest 10% of citizens earning 219,003 per year while the poor average 14,731, a ratio of 14.9 to 1.

Castres has designated Castres as its capital city, conscripts often volunteer for a second tour of duty so they can get a ticket to next year's Army Revue, Leader has just been declared ruler of Castres in an international press conference, and Roman Catholicism has been named as Castres's national religion. Crime is moderate, with the police force struggling against a lack of funding and a high mortality rate. Castres's national animal is the raven and its national religion is Roman Catholicism.

Castres is ranked 157,348^th in the world and 32^nd in Cities for Largest Black Market, with 990 billion Standard Monetary Units.
