The Commonwealth of Tranquility Antioch is a titanic, efficient nation, ruled by Sovereign with an iron fist, and remarkable for its public floggings, compulsory military service, and unlimited-speed roads. The hard-nosed, hard-working, cynical, humorless, devout population of 15.386 billion Tranquility Antiochians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The enormous, corrupt, well-organized government juggles the competing demands of Industry, Law & Order, and Defense. It meets to discuss matters of state in the capital city of Mesopotamia. Citizens pay a flat income tax of 82.8%.

The frighteningly efficient Tranquility Antiochian economy, worth a remarkable 2,151 trillion Gold coins a year, is led by the Arms Manufacturing industry, with major contributions from Retail, Uranium Mining, and Furniture Restoration. Black market activity is rampant. State-owned companies are reasonably common. Average income is an impressive 139,818 Gold coins, but there is a significant disparity between incomes, with the richest 10% of citizens earning 445,421 per year while the poor average 33,389, a ratio of 13.3 to 1.

An enormous health awareness programme is underway, waste collection professionals have been canned, most people think algebra is something a mermaid wears, and toothpaste is a mealtime delicacy. Crime, especially youth-related, is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Tranquility Antioch's national animal is the falcon, which is also the nation's favorite main course, and its national religion is Melchizedek.

Tranquility Antioch is ranked 7,077^th in the world and 10^th in Ancient for Largest Black Market, with 997 trillion Standard Monetary Units.
