The United Socialist States of Sentinopolis is a massive, environmentally stunning nation, ruled by Ntmítri Petrén'ko with an iron fist, and remarkable for its compulsory military service, free-roaming dinosaurs, and punitive income tax rates. The compassionate, cynical population of 1.46 billion Sentonians are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The enormous, socially-minded, well-organized government juggles the competing demands of Administration, Defense, and Education. It meets to discuss matters of state in the capital city of Artemkogrod. The average income tax rate is 76.7%, and even higher for the wealthy.

The strong Sentonian economy, worth 119 trillion Drachmas a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is dominated by the Tourism industry, with significant contributions from Arms Manufacturing, Beef-Based Agriculture, and Book Publishing. Average income is 81,799 Drachmas, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Uprooting flowers for religious ceremonies is a felony, conductors wield diamond-encrusted batons to fit in with their freshly gilded surroundings, pre-takeoff checks last longer than the flights themselves, and a video of Ntmítri Petrén'ko wearing shock-blue face paint and smashing an electric guitar in front of a frenzied crowd is on endless repeat on the nightly news. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Sentinopolis's national animal is the Bear, which frolics freely in the nation's many lush forests.

Sentinopolis is ranked 257,579^th in the world and 1,283^rd in the Plains of Perdition for Largest Insurance Industry, scoring -6.32 on the Risk Expulsion Effectiveness Rating.
