The Holy Empire of Mare B Fiore is a very large, cultured nation, notable for its burgeoning Mouse population. The compassionate, hard-working, cynical, devout population of 425 million Mare B Fioreans are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, well-organized government juggles the competing demands of Spirituality, Administration, and Law & Order. The average income tax rate is 32.4%.

The Mare B Fiorean economy, worth 21.4 trillion Golds a year, is fairly diversified and led by the Tourism industry, with major contributions from Basket Weaving, Trout Farming, and Beef-Based Agriculture. State-owned companies are reasonably common. Average income is 50,269 Golds, and evenly distributed, with the richest citizens earning only 3.3 times as much as the poorest.

Bicyclists are banned from major roads, the airship business has been driven out of the country by strict regulations and high fines, the flight attendant who draws the short straw is on "cockpit bucket duty", and bridge salesmen line up for blocks to make their cases at Leader's office. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mare B Fiore's national animal is the Mouse, which frolics freely in the nation's many lush forests.

Mare B Fiore is ranked 160,603^rd in the world and 1^st in Fantasy Zone for Most Developed, scoring 54.83 on the Human Development Index.
