The Republic of Mysterium is a massive, genial nation, renowned for its lack of airports, suspicion of poets, and devotion to social welfare. The compassionate, devout population of 1.322 billion Mysteriumians 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 large government juggles the competing demands of Law & Order, Welfare, and Spirituality. The average income tax rate is 46.0%, but much higher for the wealthy.

The strong Mysteriumian economy, worth 74.6 trillion Coppers a year, is led by the Trout Farming industry, with major contributions from Tourism, Uranium Mining, and Information Technology. State-owned companies are common. Average income is 56,402 Coppers, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

The transit system is throwing poor people under the bus, returning vacationers often find that their property is now a construction site, the nation threatens sanctions on islands only visible at low tide, and the new national mascot has to be wheeled onto the field of play. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Mysterium's national animal is the Swan, which is also the nation's favorite main course.

Mysterium is ranked 112,876^th in the world and 1,427^th in the South Pacific for Most Developed, scoring 59.29 on the Human Development Index.
