The Republic of Great Yin is a very large, socially progressive nation, remarkable for its irreverence towards religion. The hard-working, democratic population of 150 million Great Yinians are effectively ruled by a group of massive corporations, who run for political office and provide their well-off citizens with world-class goods and services. Their poorer citizens, however, are mostly starving to death while being urged to go out and get real jobs. The populace has reasonably extensive civil rights, although these are mostly aimed at allowing them to buy whatever they like.

The tiny government juggles the competing demands of Healthcare, Education, and Defense. Citizens pay a flat income tax of 7.4%.

The thriving Great Yinian economy, worth 11.7 trillion LMDS a year, is broadly diversified and led by the Uranium Mining industry, with major contributions from Furniture Restoration, Beef-Based Agriculture, and Information Technology. Average income is 77,982 LMDS, but there is a large disparity between incomes, with the richest 10% of citizens earning 302,436 per year while the poor average 13,773, a ratio of 22.0 to 1.

Traumatised refugees have a full bedpan shoved into their hands along with their immigration papers, the only thing that can pin down a "superhero" is red tape, companies have begun running campaigns to stop people from remembering their brand name, and selling your granddad's clothes requires an incredible amount of paperwork. Crime is moderate, with the police force struggling against a lack of funding and a high mortality rate. Great Yin's national animal is the fox, which frolics freely in the nation's many lush forests.

Great Yin is ranked 41,342^nd in the world and 23^rd in Audinesca for Highest Food Quality, scoring 39.4 on the Meeshlin-Starr Index.
