The Kingdom of Lengo is a gargantuan, socially progressive nation, ruled by King Richard IV with an even hand, and remarkable for its complete lack of prisons, digital currency, and zero percent divorce rate. The compassionate population of 15.462 billion Yorkshiremen have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The large government prioritizes Education, with Healthcare, Environment, and Industry also on the agenda, while Spirituality is ignored. It meets to discuss matters of state in the capital city of York. The average income tax rate is 70.8%, and even higher for the wealthy.

The frighteningly efficient Northern economy, worth a remarkable 1,732 trillion Caps a year, is led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Trout Farming. State-owned companies are common. Average income is an impressive 112,066 Caps, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Government-funded marriage counseling is showing very limited success, political speeches always take place at sunset to a background of patriotic power ballads, collisions between bicycles and carnival floats are on the rise, and it's normal to start working life with crippling financial debt. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Lengo's national animal is the Lion, which is also the nation's favorite main course, and its national religion is Church of York.

Lengo is ranked 15,446^th in the world and 8^th in The Fallout Wasteland for Most Scientifically Advanced, scoring 323.97 on the Kurzweil Singularity Index.
