The Kingdom of Pe-Ne-Dumo is a huge, safe nation, remarkable for its barren, inhospitable landscape, public floggings, and feral children. The hard-nosed, cynical population of 790 million Pe-Ne-Dumoans are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, corrupt, well-organized government juggles the competing demands of Defense, Law & Order, and Education. The average income tax rate is 38.7%, but much higher for the wealthy.

The thriving Pe-Ne-Dumoan economy, worth 76.2 trillion Reais a year, is broadly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Soda Sales, and Uranium Mining. Black market activity is notable. Average income is 96,428 Reais, and distributed extremely evenly, with little difference between the richest and poorest citizens.

This year's hottest fashion trend is the Lese Majeste collection, blind students are at a disadvantage now that test papers printed in braille have been discontinued, when flight control tells pilots to alter course the usual reply is "No, YOU move!", and warfare increasingly resembles a video game. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Pe-Ne-Dumo's national animal is the Great Skua, which is also the nation's favorite main course.

Pe-Ne-Dumo is ranked 237,844^th in the world and 96^th in Eientei Gensokyo for Most Beautiful Environments, with 347.43 pounds of wildlife per square mile.
