The Principality of Haeduedeu is a titanic, efficient nation, ruled by Queen Ljubica Fenn with an iron fist, and renowned for its barren, inhospitable landscape, deadly medical pandemics, and state-planned economy. The hard-nosed, cynical, humorless population of 21.676 billion Haeduedeuans are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The enormous, corrupt, moralistic government juggles the competing demands of Law & Order, Defense, and Administration. The average income tax rate is 91.1%, and even higher for the wealthy.

The frighteningly efficient Haeduedeuan economy, worth a remarkable 2,713 trillion Sepis a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, quite specialized black market in Uranium Mining, Arms Manufacturing, Woodchip Exports, and Furniture Restoration. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 125,183 Sepis, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Harry Potter books are banned, internet moderator is one of the most popular jobs among the nation's more socially awkward citizens, bridge salesmen line up for blocks to make their cases at Queen Ljubica Fenn's office, and the sun rises an hour later on border communities. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Haeduedeu's national animal is the worm, which is also the nation's favorite main course.

Haeduedeu is ranked 69,932^nd in the world and 2^nd in Eruditio for Most Developed, scoring 70.67 on the Human Development Index.
