The Principality of Leff Impirester is a massive, efficient nation, ruled by His Royal Highness the Prince with an iron fist, and notable for its smutty television, suspicion of poets, and stringent health and safety legislation. The hard-nosed, cynical, humorless population of 3.248 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, moralistic, well-organized government prioritizes Defense, although Law & Order, Industry, and Education are also considered important, while Welfare and Social Policy are ignored. It meets to discuss matters of state in the capital city of Impirester City. The average income tax rate is 46.2%, but much higher for the wealthy.

The frighteningly efficient Leff Impiresterian economy, worth 498 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 153,523 deniers, and evenly distributed, with the richest citizens earning only 2.2 times as much as the poorest.

New pilots are regularly reminded that they are more expendable than their planes, citizens seem fixated on 105m x 45m rectangles, pareidolic SETI scientists swear there's a message from aliens hidden within pi, and no one believes anything until it has been strenuously tested and peer-reviewed. 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 211,481^st in the world and 8,342^nd in Lazarus for Safest, scoring 32.83 on the Bubble-Rapp Safety Rating.
