The Domain Expansion of Cools is a colossal, cultured nation, ruled by Cools with an iron fist, and remarkable for its zero percent divorce rate, compulsory military service, and triple-decker prams. The hard-nosed, hard-working, cynical population of 4.589 billion Coolsians 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 relatively small, moralistic, well-organized government juggles the competing demands of Defense, Administration, and Law & Order. It meets to discuss matters of state in the capital city of The Infinite Void. Citizens pay a flat income tax of 15.4%.

The powerhouse Coolsian economy, worth 376 trillion Cools a year, is broadly diversified and led by the Uranium Mining industry, with major contributions from Arms Manufacturing, Trout Farming, and Furniture Restoration. State-owned companies are common. Average income is 82,094 Cools, but there is a significant disparity between incomes, with the richest 10% of citizens earning 249,499 per year while the poor average 20,983, a ratio of 11.9 to 1.

Merchant ships always travel line astern in Coolsian waters, neon signs promoting safe driving often distract drivers, troublemakers boast about how many times they have to visit their therapist, and Cools has taken to wearing medal-adorned military uniform in all public appearances. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Cools's national animal is the Silly Cats, which can occasionally be seen sifting through garbage in the nation's cities, and its national religion is Coolsism.

Cools is ranked 90,376^th in the world and 3^rd in Cools Established Barrier for Highest Food Quality, scoring 27.61 on the Meeshlin-Starr Index.
