The Commonwealth of Jarilon is a titanic, cultured nation, ruled by Zanon Dance with an iron fist, and remarkable for its frequent executions, daily referendums, and keen interest in outer space. The hard-nosed, hard-working, cynical population of 17.186 billion Jarilonians 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 large, corrupt government juggles the competing demands of Education, Administration, and Environment. It meets to discuss matters of state in the capital city of Sate. The average income tax rate is 94.2%.

The frighteningly efficient Jarilonian economy, worth a remarkable 2,835 trillion Marks a year, is quite specialized and led by the Information Technology industry, with major contributions from Book Publishing, Tourism, and Beef-Based Agriculture. Average income is an impressive 164,985 Marks, and evenly distributed, with the richest citizens earning only 3.5 times as much as the poorest.

People with hippopotomonstrosesquippedaliophobia faint upon diagnosis, the government loves seeing the little people fight, aid workers deliver life-saving supplies with a devious gleam in their eyes, and cultural heritage is measured in Scoville Heat Units. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Jarilon's national animal is the Barn Owl, which is also the nation's favorite main course, and its national religion is Thelema.

Jarilon is ranked 10,793^rd in the world and 240^th in the South Pacific for Most Scientifically Advanced, scoring 411.8 on the Kurzweil Singularity Index.
