The Diabolical Imperium of Gehenna Primus is a colossal, cultured nation, ruled by The Malificar with an iron fist, and notable for its complete lack of prisons, public floggings, and free-roaming dinosaurs. The hard-nosed, hard-working, cynical, humorless population of 5.018 billion Gehennans are ruled with an iron fist by the corrupt, dictatorship government, which oppresses anyone who isn't on the board of a Fortune 500 company. Large corporations tend to be above the law, and use their financial clout to gain ever-increasing government benefits at the expense of the poor and unemployed.

The relatively small, corrupt, pro-business, well-organized government is primarily concerned with Defense, although Law & Order, Education, and Industry are also considered important, while Social Policy and Welfare are ignored. It meets to discuss matters of state in the capital city of Chernograd. Citizens pay a flat income tax of 49.8%.

The frighteningly efficient Gehennan economy, worth a remarkable 2,042 trillion Imperial Credits a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Information Technology, Retail, and Uranium Mining. Black market activity is rampant. Average income is an amazing 407,055 Imperial Credits, but there is a large disparity between incomes, with the richest 10% of citizens earning 2,012,215 per year while the poor average 46,803, a ratio of 43.0 to 1.

The optimally efficient parking strategy for business commuters is referred to as the "traveling salesman problem", breast milk lattes are the newest fad among hip urbanites, companies have begun running campaigns to stop people from remembering their brand name, and drunk drivers are sentenced to death. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Gehenna Primus's national animal is the Dragon, which is also the nation's favorite main course, and its national religion is nonexistent.

Gehenna Primus is ranked 1,363^rd in the world and 2^nd in Hell for Most Scientifically Advanced, scoring 910.68 on the Kurzweil Singularity Index.
