The Principality of Leff Impirester is a massive, orderly nation, ruled by His Royal Highness the Prince with an iron fist, and renowned for its frequent executions, free-roaming dinosaurs, and enslaved workforce. The hard-nosed, cynical, humorless population of 3.155 billion Leff Impiresterians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government prioritizes Defense, although Law & Order, Industry, and Healthcare are also considered important, while Welfare and Social Policy aren't funded at all. It meets to discuss matters of state in the capital city of Impirester City. The average income tax rate is 35.5%, but much higher for the wealthy.

The all-consuming Leff Impiresterian economy, worth 454 trillion deniers a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Arms Manufacturing, Retail, and Uranium Mining. Black market activity is rampant. State-owned companies are common. Average income is an impressive 143,978 deniers, and evenly distributed, with the richest citizens earning only 2.7 times as much as the poorest.

Actively encouraging climate change is helping reduce winter fuel costs, former gun owners are finding that brandishing paintball guns isn't as satisfying as the real thing, directors of low-budget sci-fi films are flocking to use Impirester City as a backdrop, and children grow up believing the sun to be a myth. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Leff Impirester's national animal is the giraffe, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Church of the God-Prince.

Leff Impirester is ranked 89,174^th in the world and 4,561^st in Lazarus for Most Cultured, scoring 67 on the Snufflebottom-Wiggendum Pentatonic Scale.
