The April Fool's Fan of Imperio de Castilho is a massive, genial nation, ruled by General Anhanguera with an even hand, and notable for its avowedly heterosexual populace, public floggings, and infamous sell-swords. The compassionate, devout population of 4.615 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, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Guaricana. The average income tax rate is 92.0%.

The frighteningly efficient Castilhian economy, worth 784 trillion dollars a year, is quite specialized and led by the Arms Manufacturing industry, with major contributions from Tourism, Information Technology, and Book Publishing. State-owned companies are common. Average income is an impressive 169,948 dollars, and evenly distributed, with the richest citizens earning only 3.3 times as much as the poorest.

Tourists are forbidden to enter Native Castilhian lands, literature classes frequently go on field trips to rock concerts, the song 'They Got an Awful Lot of Coffee in Imperio de Castilho' is a smash hit, and fifteen-year-olds cannot walk younger siblings to school without a professional Childcare and Education Certificate. 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 280,158^th in the world and 5,085^th in The North Pacific for Highest Disposable Incomes, with 13,595.84 Standard Monetary Units.
