The Isolated Kingdom of ArkdunhAm is a gargantuan, cultured nation, ruled by King Hastur IV with an iron fist, and remarkable for its closed borders, pith helmet sales, and punitive income tax rates. The hard-nosed, cynical, humorless, devout population of 10.395 billion Arkians 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 medium-sized, corrupt, moralistic, well-organized government is primarily concerned with Defense, although Spirituality, Administration, and Industry are also considered important, while Welfare and Social Policy aren't funded at all. It meets to discuss matters of state in the capital city of Relyeh. The average income tax rate is 67.5%.

The all-consuming Arkian economy, worth a remarkable 1,525 trillion florins 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 Arms Manufacturing, Uranium Mining, and Gambling. 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 146,730 florins, and evenly distributed, with the richest citizens earning only 3.3 times as much as the poorest.

Loss of the ability to speak is a common affliction of the elderly, grade school teachers mark homework with red "CITATION NEEDED" stamps, all industry is owned and run by the government, and nobody ever seems to enter or leave the armour-plated flying castle that serves as the seat of government. Crime is a serious problem, with the police force struggling against a lack of funding and a high mortality rate. ArkdunhAm's national animal is the bat, which teeters on the brink of extinction due to toxic air pollution, and its national religion is The Esoteric Cult of Dagon.

ArkdunhAm is ranked 246,357^th in the world and 10^th in Cinderia for Largest Pizza Delivery Sector, scoring -11.77 on the Pepperoni Propulsion Productivity Index.
