The Interuniversal Imperium of The Great Imperator Jeffrey is a gargantuan, environmentally stunning nation, ruled by God-Imperator Jeffrey with an iron fist, and remarkable for its closed borders, enslaved workforce, and sprawling nuclear power plants. The hard-nosed, cynical, humorless, devout population of 12.812 billion Jeffrians are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The medium-sized, corrupt, moralistic, well-organized government prioritizes Defense, with Law & Order, Industry, and Education also on the agenda, while Social Policy and International Aid receive no funds. It meets to discuss matters of state in the capital city of Jeffopolis. The average income tax rate is 99.5%.

The frighteningly efficient Jeffrian economy, worth a remarkable 6,307 trillion Jeffrian Credits 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 an enormous, deeply entrenched, broadly diversified black market in Arms Manufacturing, Information Technology, Uranium Mining, 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 amazing 492,338 Jeffrian Credits, and evenly distributed, with the richest citizens earning only 2.0 times as much as the poorest.

Endangered bison are herded across the border to prevent them from trampling on native prairie grass, political activists are routinely executed, the government is a proud sponsor of the National Gaming Association, and stealing from a clothesline is a serious offence. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. The Great Imperator Jeffrey's national animal is the Jeffrian Serpent, which frolics freely in the nation's many lush forests, and its national religion is Jeffrey's Personality Cult.

The Great Imperator Jeffrey is ranked 2,064^th in the world and 3^rd in The United Federations for Most Scientifically Advanced, scoring 802.64 on the Kurzweil Singularity Index.
