The Fiefdom of Ueaio is a gargantuan, orderly nation, ruled by Arthur Jackson Adamson with an iron fist, and remarkable for its barren, inhospitable landscape, irreverence towards religion, and complete absence of social welfare. The hard-nosed, hard-working, cynical population of 10.906 billion Ueaioans 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 tiny, well-organized government juggles the competing demands of Defense, Law & Order, and Public Transport. It meets to discuss matters of state in the capital city of New Vegas. The average income tax rate is 9.1%.

The strong Ueaioan economy, worth 605 trillion lire a year, is fairly diversified and led by the Arms Manufacturing industry, with major contributions from Uranium Mining, Door-to-door Insurance Sales, and Furniture Restoration. Average income is 55,559 lire, and evenly distributed, with the richest citizens earning only 4.9 times as much as the poorest.

TV shows must meet strict ethnicity quotas, the government has adopted a more thrifty attitude to administrating the country's needs, Arthur Jackson Adamson has been self-declared as the Most Supreme Magnificent Overlord of Everything You Ever Saw, and Zoroastrianism has been named as Ueaio's national religion. Crime is moderate. Ueaio's national animal is the wolf, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Zoroastrianism.

Ueaio is ranked 245,738^th in the world and 3^rd in Uoiea for Lowest Crime Rates, with 53.3 law-abiding acts per hour.
