The Holy Empire of Yeffin is a mammoth, cultured nation, ruled by King Barb IV with an even hand, and remarkable for its museums and concert halls, daily referendums, and absence of drug laws. The hard-nosed, hard-working, democratic, devout population of 7.626 billion Yeffinish 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 relatively small government juggles the competing demands of Industry, Education, and Environment. It meets to discuss matters of state in the capital city of Colhei. Citizens pay a flat income tax of 15.9%.

The frighteningly efficient Yeffinish economy, worth a remarkable 1,091 trillion dollarbucks a year, is fairly diversified and led by the Tourism industry, with significant contributions from Retail, Book Publishing, and Arms Manufacturing. Average income is an impressive 143,177 dollarbucks, but there is a large disparity between incomes, with the richest 10% of citizens earning 602,426 per year while the poor average 22,082, a ratio of 27.3 to 1.

It is said that the captain goes down with the ship but ecological protection goes up, ex-cons are paid to remain law-abidingly dull, men who wear pink are seen as dangerously unmanly, and modesty is treated with the side-eye. Crime is totally unknown. Yeffin's national animal is the jackalope, which frolics freely in the nation's many lush forests, and its national religion is Christianity.

Yeffin is ranked 152,298^th in the world and 6,447^th in Lazarus for Most Accessible, scoring 262.4 on the Keller-Reeve Index.
