The Department of Ille-et-Vilaine is a gargantuan, efficient nation, ruled by Hoël Kerprigent with an even hand, and remarkable for its frequent executions, compulsory military service, and suspicion of poets. The hard-nosed, hard-working, devout population of 21.907 billion Brétilliens 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, moralistic government juggles the competing demands of Law & Order, Defense, and Spirituality. It meets to discuss matters of state in the capital city of Rennes. Citizens pay a flat income tax of 40.8%.

The very strong Brétillien economy, worth a remarkable 1,315 trillion francs a year, is broadly diversified and led by the Arms Manufacturing industry, with significant contributions from Woodchip Exports, Information Technology, and Trout Farming. State-owned companies are common. Average income is 60,052 francs, with the richest citizens earning 5.6 times as much as the poorest.

Sullen teenagers in bright orange 'community payback' onesies can be seen picking litter at the roadside, five-year-olds chanting "Little Miss Muffet" are accused of bullying arachnophobes, students abandon classrooms for online education, and cyclists spend more time unlocking their bicycles than they do cycling. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Ille-et-Vilaine's national animal is the ermine, which frolics freely in the nation's many lush forests, and its national religion is Roman Catholicism.

Ille-et-Vilaine is ranked 139,264^th in the world and 27^th in Department Store for Most Extensive Public Healthcare, scoring 1,327.83 on the Theresa-Nightingale Rating.
