The Key of Undo is a mammoth, cultured nation, ruled by ɹ̵n̷S̷ǝ̷ʇ̷x̵ᴉ̷W̸ǝ̸┴ ƃ̵u̶ᴉ̶s̷s̸ with an iron fist, and notable for its rum-swilling pirates, soft-spoken computers, and absence of drug laws. The compassionate, cynical population of 6.219 billion Undones are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The medium-sized, socially-minded government prioritizes Defense, although Administration, Industry, and Law & Order are also considered important, while International Aid is ignored. It meets to discuss matters of state in the capital city of The Undone Capital. The average income tax rate is 41.2%, but much higher for the wealthy.

The powerhouse Undoan economy, worth 545 trillion Undoes a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a slick, highly efficient black market in Tourism, Information Technology, Arms Manufacturing, and Cheese Exports. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is 87,788 Undoes, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The nation's police officers are famously miserable-looking, fancy dress parties are raided by military police for new recruits, tech-mad citizens think that the laser-powered bread-slicer uPhone App is the coolest thing since sliced bread, and mechanics are often exhausted by their work. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Undo's national animal is the Undo, which frolics freely in the nation's many lush forests.

Undo is ranked 269,665^th in the world and 14,529^th in Osiris for Largest Trout Fishing Sector, scoring -5.29 on the Nemo Depletion Efficiency Index.
