The Most Serene Republic of Roisin Dubh is a titanic, efficient nation, ruled by His Most Serene Mark with an iron fist, and renowned for its complete lack of prisons, national health service, and stringent health and safety legislation. The compassionate, cynical, cheerful population of 13.423 billion Roisin Dubhians are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The enormous, socially-minded government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of Tír na nÓg. The average income tax rate is 99.8%.

The frighteningly efficient Roisin Dubhian economy, worth a remarkable 2,442 trillion Florins a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Tourism industry, with significant contributions from Information Technology, Book Publishing, and Basket Weaving. Average income is an impressive 181,994 Florins, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Vaccinations are mandatory, billions of Florins are spent to take high-quality photos of the Wolf Nebula, surrogate mothers are encouraged to refer to their wombs as 'rental space', and the consent form for routine blood pressure measurement has been nominated for the 'Novel Of The Year' award. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Roisin Dubh's national animal is the Wolf, which frolics freely in the nation's many lush forests.

Roisin Dubh is ranked 328,774^th in the world and 362^nd in 10000 Islands for Largest Insurance Industry, scoring -20.33 on the Risk Expulsion Effectiveness Rating.
