The Sewers of Rat Empire is a massive, safe nation, ruled by Rat King with an even hand, and remarkable for its state-planned economy, irreverence towards religion, and stringent health and safety legislation. The hard-nosed population of 1.321 billion Rats are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The medium-sized, socially-minded government juggles the competing demands of Education, Defense, and Industry. It meets to discuss matters of state in the capital city of Protogen city. The average income tax rate is 59.2%, and even higher for the wealthy.

The powerhouse Ratty economy, worth 154 trillion Scraps a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a slick, highly efficient, broadly diversified black market in Information Technology, Tourism, Arms Manufacturing, and Beef-Based Agriculture. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 117,092 Scraps, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

'Coloniser-in-Chief' has become Rat King's new moniker, Brasilistanis face layers of paperwork in a different language just to visit a doctor, 50% of adverts on children's television are for clothes made of cotton wool, and patriotic citizens chant "there's only one Rat Empire" at foreigners. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Rat Empire's national animal is the Rat, which frolics freely in the nation's many lush forests, and its national religion is None.

Rat Empire is ranked 78,337^th in the world and 1,008^th in the South Pacific for Largest Insurance Industry, scoring 2,750.37 on the Risk Expulsion Effectiveness Rating.
