The Empire of Imperium Sempiternum is a titanic, cultured nation, notable for its frequent executions, digital currency, and complete lack of prisons. The hard-nosed, cynical, devout population of 11.568 billion Imperium Sempiternumians 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 juggles the competing demands of Defense, Education, and Healthcare. It meets to discuss matters of state in the capital city of Imperium. The average income tax rate is 82.8%, and even higher for the wealthy.

The frighteningly efficient Imperium Sempiternumian economy, worth a remarkable 1,941 trillion Pound Sterlings a year, is broadly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Tourism, and Book Publishing. State-owned companies are common. Average income is an impressive 167,820 Pound Sterlings, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The face of Leader is a permanent feature of the Imperium skyline, Brancaland has gifted over nine thousand putrid moose carcasses to Imperium Sempiternum as a reminder of their "special relationship", etiquette guides advise visitors to 'grovel gracefully', and public buses smell like litter boxes. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Imperium Sempiternum's national animal is the Lion, which is also the nation's favorite main course.

Imperium Sempiternum is ranked 294,941^st in the world and 3,963^rd in the South Pacific for Fattest Citizens, with 5.29 Obesity Rate.
