The Commonwealth of Zylderia is a gargantuan, efficient nation, ruled by Zylander Reeves with an even hand, and remarkable for its museums and concert halls, vat-grown people, and national health service. The compassionate, hard-working, humorless, devout population of 13.297 billion Zylderians 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 government juggles the competing demands of Defense, Industry, and Law & Order. It meets to discuss matters of state in the capital city of Zylea. The average income tax rate is 62.5%.

The all-consuming Zylderian economy, worth a remarkable 1,472 trillion Zylds a year, is broadly diversified and dominated by the Tourism industry, with significant contributions from Arms Manufacturing, Automobile Manufacturing, and Information Technology. State-owned companies are common. Average income is an impressive 110,757 Zylds, with the richest citizens earning 5.2 times as much as the poorest.

Emojis are the soul of wit, cassocked priests and choirboys believe that what happens behind closed doors stays behind closed doors, the nation's reputation for treachery has left it sidelined on the international stage, and whenever pilots have to bail out the government bails out their company. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Zylderia's national animal is the Golden Eagle, which soars majestically through the nation's famously clear skies, and its national religion is Zyldeism.

Zylderia is ranked 48,216^th in the world and 4^th in Jyzeria for Largest Governments, scoring 22.76 on the Bureaucratic Comprehensiveness Rating Scale Index.
