The Immortal Realm of Sirius Zenith is a colossal, cultured nation, ruled by The Emperor with an iron fist, and renowned for its frequent executions, prohibition of alcohol, and zero percent divorce rate. The hard-nosed, cynical, humorless, devout population of 3.776 billion Zenithians 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 prioritizes Defense, with Education, Law & Order, and Administration also on the agenda, while International Aid is ignored. It meets to discuss matters of state in the capital city of Sanctum Imperialis Palatine. The average income tax rate is 91.8%, and even higher for the wealthy.

The frighteningly efficient Zenithian economy, worth 833 trillion Imperial Credits a year, is fairly diversified and led by the Arms Manufacturing industry, with major contributions from Information Technology, Tourism, and Beef-Based Agriculture. Black market activity is frequent. Average income is an amazing 220,866 Imperial Credits, and evenly distributed, with the richest citizens earning only 2.6 times as much as the poorest.

Going on a diet invalidates your passport, the nation's museums are real penny-pinchers, the military has adopted a weird double-fisted salute, and military minds worry that 'the blue screen of death' on brand new operating systems may be a literal description. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Sirius Zenith's national animal is the Aquila, which frolics freely in the nation's many lush forests, and its national religion is Imperial Truth.

Sirius Zenith is ranked 3,391^st in the world and 10^th in Wintreath for Most Scientifically Advanced, scoring 667.69 on the Kurzweil Singularity Index.
