The Empire of Amestris-Britannia is a gargantuan, genial nation, ruled by Kitsune with an even hand, and remarkable for its frequent executions, digital currency, and infamous sell-swords. The quiet, industrious population of 13.68 billion Amestris-Britannians 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 government — a sprawling, bureaucracy-choked morass — juggles the competing demands of Healthcare, Education, and Environment. It meets to discuss matters of state in the capital city of Amestris. The average income tax rate is 82.6%, and even higher for the wealthy.

The frighteningly efficient Amestris-Britannian economy, worth a remarkable 1,034 trillion Sekkis a year, is highly specialized and led by the Book Publishing industry, with major contributions from Information Technology, Uranium Mining, and Basket Weaving. State-owned companies are reasonably common. Average income is 75,632 Sekkis, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Bemused citizens are encouraged to sing foreign-language hymns of religions they have never heard of, couples kissing on the street are detained for 'unlawful exchange of genetic material', Amestris has restaurants serving every meat from aardvark to zebra, and a ban on unsolicited cold calling in all forms is in effect. Crime is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Amestris-Britannia's national animal is the Fox, which frolics freely in the nation's many lush forests, and its national religion is Freedom of worship.

Amestris-Britannia is ranked 131,580^th in the world and 2,787^th in The North Pacific for Largest Gambling Industry, scoring 797.6 on the Kelly Criterion Productivity Index.
