The Kingdom of Sedunn is a gargantuan, socially progressive nation, ruled by Vimmru II with a fair hand, and notable for its anti-smoking policies, compulsory military service, and stringent health and safety legislation. The compassionate, democratic population of 22.687 billion Sedunners are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The enormous government juggles the competing demands of Healthcare, Education, and Environment. It meets to discuss matters of state in the capital city of Grovne. The average income tax rate is 89.1%, and even higher for the wealthy.

The frighteningly efficient Sedunnic economy, worth a remarkable 2,133 trillion tenns a year, is highly specialized and mostly made up of the Tourism industry, with major contributions from Book Publishing and Automobile Manufacturing. State-owned companies are common. Average income is 94,060 tenns, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Films are funded in accordance with the volume of tears shed when reading the screenplay, government theft from poor artists to give to rich allies has been dubbed the "reverse Robin Hood" policy, a primitive society is being eroded as its youth flock to the modern world, and Sedunnic novella fans become unusually flustered when thinking about Vimmru II. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Sedunn's national animal is the blackbird, which soars majestically through the nation's famously clear skies.

Sedunn is ranked 9,580^th in the world and 226^th in the South Pacific for Most Advanced Public Education, scoring 11,402.49 on the Edu-tellignce® Test Score.
