The Community of Yvelines is a gargantuan, cultured nation, remarkable for its state-planned economy, compulsory military service, and stringent health and safety legislation. The hard-nosed, devout population of 14.244 billion Yvelinesians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized government juggles the competing demands of Defense, Law & Order, and Education. The average income tax rate is 42.9%, but much higher for the wealthy.

The strong Yvelinesian economy, worth 985 trillion denars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a slick, highly efficient, broadly diversified black market in Arms Manufacturing, Trout Farming, Book Publishing, and Basket Weaving. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is 69,170 denars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Orphans would rather live their life of luxury than be adopted by prospective parents, nature reserves often contain artificial waterfalls and concrete paths, smoking is banned in public areas, and 200 mph car chases are a frequent sight on the otherwise empty motorways. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Yvelines's national animal is the dragon, which soars majestically through the nation's famously clear skies.

Yvelines is ranked 65,687^th in the world and 18^th in Lennart for Safest, scoring 97.83 on the Bubble-Rapp Safety Rating.
