The April Fool's Fan of Imperio de Castilho is a massive, safe nation, ruled by General Anhanguera with an even hand, and remarkable for its museums and concert halls, keen interest in outer space, and frequent executions. The compassionate, hard-working, devout population of 3.319 billion Castilhians 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 large, corrupt government juggles the competing demands of Defense, Law & Order, and Administration. It meets to discuss matters of state in the capital city of Guaricana. The average income tax rate is 84.2%.

The frighteningly efficient Castilhian economy, worth 523 trillion dollars a year, is led by the Arms Manufacturing industry, with major contributions from Tourism, Information Technology, and Book Publishing. Average income is an impressive 157,625 dollars, and evenly distributed, with the richest citizens earning only 3.1 times as much as the poorest.

The derisively named "Morlocks of Moria" futilely demand time in the sun, the country's population is reported with a margin of error of several billions, most barbers are also surgeons, and mantis shrimp studies is academia's fastest-growing field. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Imperio de Castilho's national animal is the fragata, which frolics freely in the nation's many lush forests, and its national religion is Christianity.

Imperio de Castilho is ranked 8,971^st in the world and 398^th in The North Pacific for Lowest Crime Rates, with 103.28 law-abiding acts per hour.
