The Most Serene Republic of Yeseul is a massive, socially progressive nation, ruled by Aliyah Iseul with an even hand, and notable for its multi-spousal wedding ceremonies, free-roaming dinosaurs, and devotion to social welfare. The compassionate population of 3.35 billion Iseulians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous, socially-minded government juggles the competing demands of Education, Administration, and Law & Order. It meets to discuss matters of state in the capital city of Iseul City. The average income tax rate is 82.0%, and even higher for the wealthy.

The frighteningly efficient Yeseulian economy, worth 374 trillion Pearls a year, is quite specialized and led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Basket Weaving. State-owned companies are common. Average income is an impressive 111,919 Pearls, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Employers are keenest on employees who lack family values, heavy industry must go to expensive lengths to dispose of waste, the arms industry is strictly regulated, and blind dates reemerge as a necessary evil in the quest for love. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Yeseul's national animal is the Black Swan, which frolics freely in the nation's many lush forests.

Yeseul is ranked 19,675^th in the world and 137^th in Europeia for Most Scientifically Advanced, scoring 282.43 on the Kurzweil Singularity Index.
