The Republic of Centurionis is a gargantuan, efficient nation, ruled by Praetorian Prefect with an iron fist, and renowned for its free-roaming dinosaurs, sprawling nuclear power plants, and flagrant waste-dumping. The hard-nosed, hard-working, cynical, humorless population of 17.239 billion Centurionisians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The relatively small, corrupt, pro-business, well-organized government prioritizes Defense, although Law & Order and Industry are also considered important, while Welfare and Environment receive no funds. It meets to discuss matters of state in the capital city of Villa Agrippa. Citizens pay a flat income tax of 4.9%.

The frighteningly efficient Centurionisian economy, worth a remarkable 5,129 trillion Dinariis a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Retail, Information Technology, and Uranium Mining. Black market activity is frequent. Average income is an amazing 297,547 Dinariis, but there is a vast disparity between incomes, with the richest 10% of citizens earning 2,320,035 per year while the poor average 9,770, a ratio of 237 to 1.

Pocket dialling is a criminal offence, the military perceives nations hit by natural disasters as "easy pickings", urban high-volume mailers now receive their mail via chauffeur-driven limousines, and replacement organs are grown in vats. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Centurionis's national animal is the Otter, which teeters on the brink of extinction due to heavy metals seepage into national waterways.

Centurionis is ranked 331,905^th in the world and 4,906^th in the Rejected Realms for Most Advanced Public Transport, scoring -7.75 on the Societal Mobility Rating.
