The Imperial Dominion of Osieana is a gargantuan, environmentally stunning nation, ruled by Emperor Joseph Krueger with an iron fist, and remarkable for its sprawling nuclear power plants, compulsory military service, and national health service. The hard-nosed, cynical, humorless, devout population of 18.374 billion Osieanans are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government is primarily concerned with Defense, although Law & Order, Education, and Administration are also considered important, while Spirituality and International Aid aren't funded at all. It meets to discuss matters of state in the capital city of Kruegaria. The average income tax rate is 50.3%.

The frighteningly efficient Osieanan economy, worth a remarkable 3,570 trillion Imperial Credits a year, is quite specialized and dominated by the Arms Manufacturing industry, with significant contributions from Information Technology, Tourism, and Book Publishing. Black market activity is rampant. State-owned companies are common. Average income is an impressive 194,346 Imperial Credits, and evenly distributed, with the richest citizens earning only 4.4 times as much as the poorest.

A traveller who once stubbed a toe on an Air Brancaland flight has been offered asylum, the nation's police officers are famously miserable-looking, record sales of 'child-whacking sticks' have been reported, and scientists are researching the best way to kill off humanity to prevent catastrophic war. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Osieana's national animal is the Dragon Hawk, which soars majestically through the nation's famously clear skies, and its national religion is Oconaism.

Osieana is ranked 26,382^nd in the world and 1^st in Stellaris Imperium for Most Beautiful Environments, with 856.98 pounds of wildlife per square mile.
