The Domínio of Invictum caeli is a mammoth, cultured nation, ruled by Calisto Mercurius with an even hand, and notable for its unlimited-speed roads, daily referendums, and national health service. The hard-nosed, hard-working, devout population of 5.197 billion Invictum caelians 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 relatively small government juggles the competing demands of Law & Order, Industry, and Education. It meets to discuss matters of state in the capital city of Eclipsis Solis. Citizens pay a flat income tax of 38.1%.

The frighteningly efficient Invictum caelian economy, worth a remarkable 1,262 trillion Lira invictas a year, is broadly diversified and led by the Tourism industry, with significant contributions from Retail, Information Technology, and Book Publishing. Average income is an amazing 242,935 Lira invictas, with the richest citizens earning 8.1 times as much as the poorest.

Government statisticians explain census inaccuracies by declaring that "Sith happens", mathematics majors learn about new ways to model their crushing debt, doomscrolling is all the rage amongst the nation's teenagers, and counselors have to sign pledges supporting gay rights before they can speak to any patients. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Invictum caeli's national animal is the Shark, which frolics freely in the nation's sparkling oceans.
