The Kaiserreich of Caverniss is a colossal, socially progressive nation, ruled by King Ainsley Roland with an even hand, and remarkable for its museums and concert halls, daily referendums, and parental licensing program. The compassionate, democratic population of 2.551 billion Cavernissans are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous, socially-minded government juggles the competing demands of Administration, Environment, and Education. It meets to discuss matters of state in the capital city of Grahamencracker. The average income tax rate is 74.8%, and even higher for the wealthy.

The thriving Cavernissan economy, worth 204 trillion Cogs a year, is fairly diversified and led by the Tourism industry, with major contributions from Book Publishing, Woodchip Exports, and Trout Farming. State-owned companies are common. Average income is 80,138 Cogs, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

The nation has opened its arms to an influx of refugees, police officers often conceal their identities to safeguard against public complaints, it is illegal to distribute Girl Guide Cookies without an advanced food hygiene diploma, and earthquake sirens are a leading cause of hearing loss. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Caverniss's national animal is the Grey Eagle, which soars majestically through the nation's famously clear skies, and its national religion is Santaism.

Caverniss is ranked 188,461^st in the world and 820^th in Europe for Largest Populations, with 2.55 billion capita.
