The Royaume of Leblancroux is a massive, environmentally stunning nation, ruled by Louis Alphonse de Bourbon with an even hand, and notable for its vat-grown people, keen interest in outer space, and punitive income tax rates. The compassionate, democratic population of 1.303 billion Leblancrouxians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large government prioritizes Education, although Healthcare, Industry, and Administration are also considered important, while Spirituality and International Aid aren't funded at all. It meets to discuss matters of state in the capital city of Paris. The average income tax rate is 71.6%, and even higher for the wealthy.

The frighteningly efficient Leblancrouxian economy, worth 137 trillion Royal Francs a year, is led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Cheese Exports. State-owned companies are common. Average income is an impressive 105,369 Royal Francs, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Grannies get pulled over for knitting pullovers while driving, a child's only Trickster Night scare is the sight of their parents dancing, Scoutmasters debate whether luxury log cabins defeat the purpose of camping, and the nation's atlases tend to go out of date every few weeks. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Leblancroux's national animal is the Rooster, which is also the nation's favorite main course.

Leblancroux is ranked 15,203^rd in the world and 244^th in Europe for Most Scientifically Advanced, scoring 326.97 on the Kurzweil Singularity Index.
