The Empire of Ultraworld is a gargantuan, efficient nation, ruled by Roboute Guilliman with an iron fist, and notable for its ubiquitous missile silos, punitive income tax rates, and complete absence of social welfare. The hard-nosed, cynical, humorless population of 13.396 billion Ultraworldians 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, moralistic, well-organized government juggles the competing demands of Defense, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Ultrabass. The average income tax rate is 66.2%, and even higher for the wealthy.

The frighteningly efficient Ultraworldian economy, worth a remarkable 2,279 trillion Tras a year, is broadly diversified and led by the Arms Manufacturing industry, with significant contributions from Information Technology, Tourism, and Beef-Based Agriculture. Black market activity is rampant. State-owned companies are common. Average income is an impressive 170,142 Tras, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Nocturnal light pollution is mostly blue, children are terrified that the 'flying police monster' will come to take them away in the night, you can't put down the nation's attitude to pet health, and diminutive Ultraworldian generals are feared for their aggressiveness. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Ultraworld's national animal is the Wolverine, which frolics freely in the nation's many lush forests.

Ultraworld is ranked 162,799^th in the world and 6,781^st in Balder for Largest Publishing Industry, scoring 1,226.98 on the Bella Potter Productivity e-Index.
