The Constitutional Monarchy of Kingdom of Castille is a massive, safe nation, renowned for its irreverence towards religion, punitive income tax rates, and stringent health and safety legislation. The compassionate, democratic population of 1.495 billion Castillians 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 government juggles the competing demands of Healthcare, Education, and Law & Order. It meets to discuss matters of state in the capital city of Jaén. The average income tax rate is 50.7%, and even higher for the wealthy.

The Castillian economy, worth 73.5 trillion Castillian Pesetas a year, is quite specialized and led by the Information Technology industry, with major contributions from Book Publishing, Woodchip Exports, and Trout Farming. State-owned companies are common. Average income is 49,188 Castillian Pesetas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

A policy of plausible deniability helps protect the government from athletic doping scandals, defense lawyers suggestively note to juries how flagrantly happy victims were, elections have become procedural nightmares due to voters persistently rejecting candidates, and Kingdom of Castille has designated Jaén as its capital city. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Kingdom of Castille's national animal is the Castillan Lion, which frolics freely in the nation's many lush forests.

Kingdom of Castille is ranked 235,578^th in the world and 17^th in NationVision Official for Highest Wealthy Incomes, with 58,833 Standard Monetary Units.
