The Dominion of Tyrrhenian Sea Islands is a gargantuan, socially progressive nation, notable for its rum-swilling pirates, frequent executions, and vat-grown people. The hard-nosed, hard-working, democratic, humorless, devout population of 16.31 billion Tyrrhenian Sea Islanders have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized, corrupt government juggles the competing demands of Defense, Education, and Public Transport. It meets to discuss matters of state in the capital city of Sassari. The average income tax rate is 41.4%, but much higher for the wealthy.

The thriving Tyrrhenianese economy, worth a remarkable 1,238 trillion Lire a year, is quite specialized and led by the Gambling industry, with major contributions from Uranium Mining, Furniture Restoration, and Retail. Black market activity is rampant. Average income is 75,945 Lire, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Drunk drivers are sent to rehabilitation paid for by the government, the regional delicacy of chocolate bombes is deadlier than an unexploded bomb, employers are gradually adapting to the alien premise of paying wages to their workers, and former slave-owners hope there are no hard feelings when they apply for jobs from their erstwhile charges. Crime is a serious problem, probably because of the absence of a police force. Tyrrhenian Sea Islands's national animal is the Sardinian Tree Frog, which teeters on the brink of extinction due to widespread deforestation.

Tyrrhenian Sea Islands is ranked 282,626^th in the world and 5^th in Non Aligned Movement for Highest Food Quality, scoring 5.42 on the Meeshlin-Starr Index.
