The Empire of Imperium Sempiternum is a colossal, environmentally stunning nation, notable for its compulsory military service, pith helmet sales, and devotion to social welfare. The hard-nosed, cynical, devout population of 6.566 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, 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 82.3%, and even higher for the wealthy.

The frighteningly efficient Imperium Sempiternumian economy, worth a remarkable 1,074 trillion Golds a year, is broadly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Book Publishing, and Tourism. Average income is an impressive 163,683 Golds, and evenly distributed, with the richest citizens earning only 2.1 times as much as the poorest.

Nobody expected the fruit inquisition, forgetting to pay your annual passport bill is a leading cause of deportations, endangered bison are herded across the border to prevent them from trampling on native prairie grass, and the nation grinds to a halt for afternoon tea. 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 Cow, which is also the nation's favorite main course.

Imperium Sempiternum is ranked 12,315^th in the world and 288^th in the South Pacific for Most Scientifically Advanced, scoring 366.37 on the Kurzweil Singularity Index.
