The Kingdom of Radiation Demon 7 is a titanic, orderly nation, renowned for its barren, inhospitable landscape, compulsory military service, and spontaneously combusting cars. The hard-nosed, hard-working, cynical, devout population of 10.86 billion Radiation Demon 7ians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The tiny, pro-business, well-organized government juggles the competing demands of Spirituality, Defense, and Law & Order. Citizens pay a flat income tax of 6.7%.

The strong Radiation Demon 7ian economy, worth 593 trillion Souls a year, is driven almost entirely by the private sector, which is broadly diversified and led by the Woodchip Exports industry, with major contributions from Arms Manufacturing, Uranium Mining, and Furniture Restoration. Average income is 54,677 Souls, but there is a vast disparity between incomes, with the richest 10% of citizens earning 352,398 per year while the poor average 3,427, a ratio of 102 to 1.

Crime is a serious problem, with the police force struggling against a lack of funding and a high mortality rate. Radiation Demon 7's national animal is the Hell Hound, which teeters on the brink of extinction due to widespread deforestation.

Radiation Demon 7 is ranked 57,560^th in the world and 65^th in Underworld for Largest Populations, with 10.9 billion capita.
