The Kingdom of Sedunn is a gargantuan, environmentally stunning nation, ruled by Vimmru II with a fair hand, and remarkable for its daily referendums, sprawling nuclear power plants, and anti-smoking policies. The compassionate, democratic population of 14.484 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, outspoken government juggles the competing demands of Education, Healthcare, and Defense. It meets to discuss matters of state in the capital city of Grovne. The average income tax rate is 76.8%, and even higher for the wealthy.

The all-consuming Sedunnic economy, worth a remarkable 1,358 trillion tenns a year, is quite specialized and dominated by the Tourism industry, with significant contributions from Book Publishing, Information Technology, and Automobile Manufacturing. State-owned companies are common. Average income is 93,762 tenns, and evenly distributed, with the richest citizens earning only 2.5 times as much as the poorest.

NationStates staff are easily recognizable by their gold-plated mansions, small children are learning a lot of new words from a teacher with Tourette Syndrome, criminals and college students are taking an interest in the government's new weed-killing program, and planes can be grounded for months simply because an inspector "didn't like the color". 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 195,785^th in the world and 7,850^th in the South Pacific for Largest Basket Weaving Sector, scoring -8.37 on the Hickory Productivity Index.
