The Imperium Aeternum of The Tiber is a gargantuan, environmentally stunning nation, ruled by Emperor Tiberius with a fair hand, and renowned for its museums and concert halls, anti-smoking policies, and punitive income tax rates. The compassionate, hard-working, democratic population of 27.79 billion Romans hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The enormous, outspoken government juggles the competing demands of Education, Defense, and Industry. It meets to discuss matters of state in the capital city of Rome. The average income tax rate is 73.7%.

The all-consuming Roman economy, worth a remarkable 2,589 trillion denarii a year, is dominated by the Tourism industry, with significant contributions from Book Publishing, Information Technology, and Automobile Manufacturing. Average income is 93,188 denarii, and evenly distributed, with the richest citizens earning only 3.5 times as much as the poorest.

Waste is frequently shipped to other countries, same-sex marriages are increasingly common, the poor are often seen pale and dizzy after selling their blood to make ends meet, 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. The Tiber's national animal is the eagle, which soars majestically through the nation's famously clear skies, and its national religion is Religio Romana.

The Tiber is ranked 73,709^th in the world and 3^rd in Roman Empire for Most Scientifically Advanced, scoring 130.61 on the Kurzweil Singularity Index.
