The Yellow City of Yunkai is a mammoth, safe nation, ruled by Octarch Hoknak mo Gadhiz with an iron fist, and remarkable for its barren, inhospitable landscape, compulsory military service, and complete absence of social welfare. The hard-nosed, hard-working, cynical, devout population of 7.986 billion Yunkaians are ruled with an iron fist by the corrupt, dictatorship government, which oppresses anyone who isn't on the board of a Fortune 500 company. Large corporations tend to be above the law, and use their financial clout to gain ever-increasing government benefits at the expense of the poor and unemployed.

The medium-sized, pro-business, well-organized government juggles the competing demands of Spirituality, Law & Order, and Defense. It meets to discuss matters of state in the capital city of Yunkai. Citizens pay a flat income tax of 25.5%.

The very strong Yunkaian economy, worth 467 trillion honors a year, is broadly diversified and led by the Pizza Delivery industry, with major contributions from Arms Manufacturing, Furniture Restoration, and Uranium Mining. Average income is 58,540 honors, but there is a significant disparity between incomes, with the richest 10% of citizens earning 181,944 per year while the poor average 14,489, a ratio of 12.6 to 1.

Yunkai has designated Yunkai as its capital city, there is a disproportionate number of poor people in prison, every new toxic waste dump comes with a seal of approval from the government's science advisor, and competing private ambulances racing to be the first to traffic accidents are a major cause of road accidents. Crime, especially youth-related, is almost non-existent, thanks to a well-funded police force. Yunkai's national animal is the harpy, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Pantheon of Old Ghis.

Yunkai is ranked 84,652^nd in the world and 149^th in The League for Most Cultured, scoring 67 on the Snufflebottom-Wiggendum Pentatonic Scale.
