The Commonwealth of Periclasea is a gargantuan, efficient nation, remarkable for its closed borders, compulsory military service, and stringent health and safety legislation. The hard-nosed, hard-working, devout population of 26.278 billion Periclaseans are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized government prioritizes Law & Order, with Industry, Administration, and Defense also on the agenda, while Welfare isn't funded at all. Citizens pay a flat income tax of 41.7%.

The powerhouse Periclasean economy, worth a remarkable 1,783 trillion sterlings a year, is fairly diversified and dominated by the Arms Manufacturing industry, with significant contributions from Book Publishing, Door-to-door Insurance Sales, and Retail. Average income is 67,858 sterlings, with the richest citizens earning 6.3 times as much as the poorest.

The might of the entire Periclasean Navy is focused on fifty bemused spear-throwing islanders, street crime is on the rise as police officers spend most of their time in prisons, soldiers with colourful mohawks make themselves perfect targets for snipers, and victims of crime are viewed as less trustworthy than politicians. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force. Periclasea's national animal is the raven, which soars majestically through the nation's famously clear skies.

Periclasea is ranked 11,363^rd in the world and 9^th in Auretania for Largest Populations, with 26.3 billion capita.
