The Swamp Forest of Overgrown Tomb is a titanic, environmentally stunning nation, ruled by Mark Rosewater with an even hand, and renowned for its ubiquitous missile silos, parental licensing program, and disturbing lack of elderly people. The compassionate, humorless population of 10.338 billion Overgrown Tombians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized, corrupt government juggles the competing demands of Defense, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Shockland. Citizens pay a flat income tax of 45.0%.

The frighteningly efficient Overgrown Tombian economy, worth a remarkable 1,370 trillion lands a year, is fairly diversified and led by the Arms Manufacturing industry, with significant contributions from Information Technology, Woodchip Exports, and Basket Weaving. Black market activity is rampant. State-owned companies are common. Average income is an impressive 132,537 lands, with the richest citizens earning 8.8 times as much as the poorest.

Weather forecasts are accurate but nobody has the bandwidth to view them, jaw strain is an increasingly common ailment, Shockland consists only of government buildings and the mansions of government janitors, and there are increasing complaints that male AI assistants have aggressive voices. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Overgrown Tomb's national animal is the shock, which frolics freely in the nation's many lush forests, and its national religion is shocking.

Overgrown Tomb is ranked 211,547^th in the world and 2^nd in Yoyleland for Most Eco-Friendly Governments, scoring 273.49 on the Dolphin Recycling Awareness Index.
