The Duchy of Talouse of Great Marsinia is a colossal, efficient nation, ruled by Duchess Lionne with an even hand, and remarkable for its compulsory military service, infamous sell-swords, and otherworldly petting zoo. The hard-working, humorless population of 6.171 billion Talousians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The enormous, corrupt government juggles the competing demands of Defense, Industry, and Education. It meets to discuss matters of state in the capital city of Talononte. The average income tax rate is 95.4%.

The frighteningly efficient Talousian economy, worth 930 trillion Francs a year, is quite specialized and led by the Information Technology industry, with major contributions from Arms Manufacturing and Furniture Restoration. Black market activity is frequent. Average income is an impressive 150,795 Francs, with the richest citizens earning 5.1 times as much as the poorest.

Cutting-edge missile systems are being retrofitted to twin-prop air force biplanes, it's rare to find an unchewed pencil, sales of disinfectant wipes have skyrocketed, and a life spent suffering in silence is considered noble. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Great Marsinia's national animal is the inexistant, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Secular.

Great Marsinia is ranked 99,740^th in the world and 17^th in Equestria at War for Safest, scoring 58.31 on the Bubble-Rapp Safety Rating.
