The Kingdom of Sedunn is a gargantuan, socially progressive nation, ruled by Vimmru II with a fair hand, and remarkable for its keen interest in outer space, compulsory military service, and devotion to social welfare. The compassionate, democratic population of 11.978 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 large, outspoken government juggles the competing demands of Education, Defense, and Healthcare. It meets to discuss matters of state in the capital city of Grovne. The average income tax rate is 74.4%, and even higher for the wealthy.

The all-consuming Sedunnic economy, worth a remarkable 1,114 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 93,030 tenns, and evenly distributed, with the richest citizens earning only 2.6 times as much as the poorest.

Public incontinence is a growing problem amongst the nation's women, kindergarten teachers with ankle-bracelets are closely supervised by their parole officers, foreigners must sell an arm and a leg to afford surgery in Sedunn, and NationStates staff are easily recognizable by their gold-plated mansions. 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 147,291^st in the world and 6,776^th in the South Pacific for Fattest Citizens, with 7.37 Obesity Rate.
