The April Fool's Fan of Imperio de Castilho is a massive, environmentally stunning nation, ruled by General Anhanguera with an even hand, and renowned for its daily referendums, infamous sell-swords, and stringent health and safety legislation. The compassionate, hard-working, devout population of 3.403 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 86.6%.

The frighteningly efficient Castilhian economy, worth 537 trillion dollars a year, is led by the Arms Manufacturing industry, with significant contributions from Tourism, Information Technology, and Book Publishing. Average income is an impressive 157,973 dollars, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

Authorities are looking for a stool pigeon to rat out who is stealing food from pigeon toilets, interviewees for teaching jobs are waterboarded to "reveal undesirable histories", military minds worry that 'the blue screen of death' on brand new operating systems may be a literal description, and when shaking hands with foreign leaders General Anhanguera wears an armoured gauntlet. Crime, especially youth-related, is totally unknown, thanks to a very 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 38,957^th in the world and 1,273^rd in The North Pacific for Safest, scoring 106.06 on the Bubble-Rapp Safety Rating.
