The Grand Duchy of Cardisdia25 is a massive, efficient nation, renowned for its enslaved workforce, keen interest in outer space, and aversion to nipples. The hard-nosed, cynical, humorless, devout population of 2.223 billion Cardisdia25ians are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The large, corrupt government juggles the competing demands of Law & Order, Defense, and Administration. The average income tax rate is 52.2%, and even higher for the wealthy.

The very strong Cardisdia25ian economy, worth 164 trillion Cards a year, is led by the Tourism industry, with major contributions from Retail, Basket Weaving, and Arms Manufacturing. Black market activity is rampant. State-owned companies are reasonably common. Average income is 74,077 Cards, and evenly distributed, with the richest citizens earning only 2.9 times as much as the poorest.

Diplomatic fallout tends to be much more dangerous than radioactive fallout, 'Mountain Doobie' is widely regarded as the nation's favourite drink, the government is deliberately installing bloatware onto computers, and immigrants who don't like the taste of Cardisdia25ian Turnip Chips are immediately deported. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Cardisdia25's national animal is the Bat or the Cow.

Cardisdia25 is ranked 167,658^th in the world and 32^nd in Cardisdia for Largest Automobile Manufacturing Sector, scoring 324.41 on the Henry Ford Productivity Index.
