The April Fool's Fan of Imperio de Castilho is a mammoth, genial nation, ruled by General Anhanguera with an even hand, and remarkable for its aversion to nipples, pith helmet sales, and ubiquitous missile silos. The compassionate, devout population of 8.445 billion Castilhians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The large, corrupt government juggles the competing demands of Administration, Defense, and Education. It meets to discuss matters of state in the capital city of Guaricana. The average income tax rate is 91.9%, and even higher for the wealthy.

The frighteningly efficient Castilhian economy, worth a remarkable 1,548 trillion dollars a year, is led by the Tourism industry, with major contributions from Arms Manufacturing, Information Technology, and Book Publishing. State-owned companies are reasonably common. Average income is an impressive 183,387 dollars, and evenly distributed, with the richest citizens earning only 2.1 times as much as the poorest.

Fraternities are rejoicing at government-subsidized partying, triple black diamond is the only ski difficulty, buses are widely regarded as the safest way to travel, and all facts are created equal. 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 16,673^rd in the world and 178^th in The North Pacific for Largest Arms Manufacturing Sector, scoring 27,915.89 on the Charon Conveyancy Index.
