The United Kingdom of Isselmere is a gargantuan, socially progressive nation, ruled by King Henry V with an even hand, and renowned for its complete lack of prisons, national health service, and keen interest in outer space. The compassionate, democratic, cheerful population of 49.992 billion Isselmerian-Nielanders are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The relatively small, socially-minded government prioritizes Education, with Defense, Social Policy, and Healthcare also on the agenda, while Spirituality and International Aid receive no funds. It meets to discuss matters of state in the capital city of Daurmont. The average income tax rate is 75.8%, and even higher for the wealthy.

The frighteningly efficient Isselmeric-Nielandic economy, worth an astonishing 13,885 trillion crowns a year, is fairly diversified and led by the Book Publishing industry, with major contributions from Information Technology, Tourism, and Arms Manufacturing. State-owned companies are common. Average income is an amazing 277,748 crowns, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Nuclear physics is the most popular course at university, internet moderator is one of the most popular jobs among the nation's more socially awkward citizens, lifelong celibates are surprised to receive government-issue condoms in the post, and excessive wheelchair ramps on government buildings have been compared to theme park attractions. Crime is totally unknown. Isselmere's national animal is the blue-backed erne, which frolics freely in the nation's many lush forests.

Isselmere is ranked 2,560^th in the world and 2^nd in Haven for Most Scientifically Advanced, scoring 747.98 on the Kurzweil Singularity Index.
