The Department of Marne is a massive, efficient nation, renowned for its barren, inhospitable landscape, compulsory military service, and restrictive gun laws. The compassionate, hard-working, democratic, devout population of 3.458 billion Marnaises are known throughout the region for their efficiency and work ethic, as well as their general suspicion of leisure.

The relatively small, moralistic government prioritizes Spirituality, with Law & Order, Welfare, and Education also on the agenda. It meets to discuss matters of state in the capital city of Châlons-en-Champagne. The average income tax rate is 12.8%.

The very strong Marnais economy, worth 257 trillion francs a year, is broadly diversified and led by the Furniture Restoration industry, with major contributions from Trout Farming, Pizza Delivery, and Uranium Mining. Average income is 74,432 francs, with the richest citizens earning 5.3 times as much as the poorest.

Teachers prefer to give 'Maybe, Maybe Not' tests when dealing with sensitive subjects, frustrated teenage boys are told that if they like it then they should have put a ring on it, CEOs can't hear the term 'Fire Sale' without bursting into tears, and citizens are forced to donate blood once every three months. Crime, especially youth-related, is totally unknown, despite the fact that it is difficult to make it through a day without breaking one of the country's many laws. Marne's national animal is the lion, which can occasionally be seen sifting through garbage in the nation's cities.

Marne is ranked 26,101^st in the world and 6^th in Department Store for Highest Disposable Incomes, with 64,905.18 Standard Monetary Units.
