The Sovereign State of Prosperoi is a mammoth, environmentally stunning nation, ruled by Lucius Severus Pertinax with a fair hand, and notable for its museums and concert halls, ritual sacrifices, and daily referendums. The compassionate, hard-working, democratic population of 9.713 billion Prosperoans hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The medium-sized, liberal government juggles the competing demands of Industry, Education, and Administration. It meets to discuss matters of state in the capital city of Civitas Cataegis. The average income tax rate is 74.8%, and even higher for the wealthy.

The frighteningly efficient Prosperoian economy, worth a remarkable 1,437 trillion Aquilas a year, is fairly diversified and led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Retail. Average income is an impressive 147,985 Aquilas, and evenly distributed, with the richest citizens earning only 2.0 times as much as the poorest.

Dictators have dubbed Prosperoi the land of lunatics, a third of Prosperoans are e-certified CEOs, the government spends more on chasing distant comets than on basic infrastructure, and tech companies are playing whack-a-mole with one-post accounts. Crime, especially youth-related, is totally unknown. Prosperoi's national animal is the Thundergrunter, which frolics freely in the nation's many lush forests.

Prosperoi is ranked 9,630^th in the world and 18^th in The Order of the Grey Wardens for Largest Welfare Programs, scoring 4,662.87 on the Safety Net Mesh Density Rating.
