The Federated Principality of Fluvannia is a colossal, efficient nation, ruled by Crown Prince Michael with a fair hand, and notable for its barren, inhospitable landscape, deadly medical pandemics, and pith helmet sales. The hard-nosed, hard-working, democratic, devout population of 5.382 billion Fluvannians enjoy some of the most opulent lifestyles in the region, unless they are unemployed or working-class, in which case they are variously starving to death or crippled by easily preventable diseases.

The relatively small, pro-business government juggles the competing demands of Education, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Oshkosh. Citizens pay a flat income tax of 34.0%.

The frighteningly efficient Fluvannian economy, worth 883 trillion Marks a year, is broadly diversified and led by the Retail industry, with major contributions from Arms Manufacturing, Information Technology, and Book Publishing. Average income is an impressive 164,109 Marks, but there is a large disparity between incomes, with the richest 10% of citizens earning 733,557 per year while the poor average 22,770, a ratio of 32.2 to 1.

Politicians stage photo ops featuring barely functional fighter jets, wheelchair users complain it is nearly impossible for them to cross the road in Oshkosh, crime is on the rise as DNA sampling has been all but outlawed, and the meaning of life was recently discovered in the patch notes for Version 1.42. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Fluvannia's national animal is the Bear, which teeters on the brink of extinction due to widespread deforestation.

Fluvannia is ranked 27,130^th in the world and 7^th in Republic of Conservative Nations for Most Pro-Market, scoring 74.11 on the Rand Index.
