The Stellar Ancient Domain of Regnum Castellae is a colossal, safe nation, ruled by King Fernando Magno with an even hand, and notable for its barren, inhospitable landscape, compulsory military service, and compulsory gun ownership. The hard-working, devout population of 3.529 billion Andarian Stellar Castillian Warriors 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 medium-sized government juggles the competing demands of Defense, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Burgos. The average income tax rate is 32.3%.

The strong Andarian Stellar Castillian Warrior economy, worth 231 trillion Maravedis a year, is fairly diversified and led by the Arms Manufacturing industry, with major contributions from Automobile Manufacturing, Uranium Mining, and Gambling. Black market activity is notable. State-owned companies are common. Average income is 65,617 Maravedis, and evenly distributed, with the richest citizens earning only 4.7 times as much as the poorest.

The government is hounded to provide tissues whenever the feelings of the Dàguó people are hurt, children are brainwashed at a young age to accept "love and peace!" as a way of life, war memorials have been modified to include hammocks for napping, and the government baselessly accuses foreign dignitaries of being assassins. Crime, especially youth-related, is almost non-existent, thanks to a capable police force and progressive social policies in education and welfare. Regnum Castellae's national animal is the Bear, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Pantheism.

Regnum Castellae is ranked 111,663^rd in the world and 3^rd in The Sagittarius Constellation for Highest Average Incomes, with 65,617.74 Standard Monetary Units.
