The Plebeian Republic of Aeternabilis is a gargantuan, environmentally stunning nation, ruled by Tribune Danica with a fair hand, and notable for its anti-smoking policies, sprawling nuclear power plants, and state-planned economy. The compassionate, democratic, cheerful population of 27.176 billion Aeternals are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The large, liberal, socially-minded, outspoken government prioritizes Education, although Healthcare, Environment, and Industry are also considered important, while Spirituality and Defense receive no funds. It meets to discuss matters of state in the capital city of Sinu Quiescis. The income tax rate is 100%.

The frighteningly efficient Aeternal economy, worth a remarkable 7,863 trillion denarii a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector is led by the Information Technology industry, with major contributions from Tourism and Book Publishing. Average income is an amazing 289,351 denarii, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

National park visitors are reporting a rash of poison ivy sightings, worship days have replaced sick days, the saying "when pigs fly" has been changed to "when the lights work", and the number of eyes rolled per maths lesson is increasing exponentially. Crime is totally unknown. Aeternabilis's national animal is the eagle, which soars majestically through the nation's famously clear skies.

Aeternabilis is ranked 332,478^th in the world and 2^nd in Aeternal Realm for Highest Unexpected Death Rate, scoring 15.09 on the Bus Surprisal Index.
