The Kingdom of Radicaster is a titanic, orderly nation, ruled by Regent Hyong Sung-Jin with an iron fist, and remarkable for its soft-spoken computers, frequent executions, and pith helmet sales. The hard-nosed, cynical, humorless population of 20.778 billion Kasterians are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, moralistic, well-organized government is effectively ruled by the Department of Defense, although Law & Order is also considered important, while International Aid and Environment receive no funds. It meets to discuss matters of state in the capital city of Gwangseong. The average income tax rate is 95.9%.

The frighteningly efficient Kasterian economy, worth an astonishing 12,712 trillion Kasterian won a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, broadly diversified black market in Arms Manufacturing and Information Technology. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is a breathtaking 611,843 Kasterian won, with the richest citizens earning 7.1 times as much as the poorest.

When flight control tells pilots to alter course the usual reply is "No, YOU move!", soldiers on first dates introduce themselves only by their ranks and serial numbers, citizens are deployed to barren deserts to protect small territorial claims, and organisations with 800 in their phone number are often raided by special forces. Crime, especially youth-related, is totally unknown, despite the fact that it is difficult to make it through a day without breaking one of the country's many laws. Radicaster's national animal is the 152 mm shell, which is also the nation's favorite main course, and its national religion is atheism.

Radicaster is ranked 16,911^th in the world and 579^th in The North Pacific for Longest Average Lifespans, with 90.82 years.
