The Imperial Federation of Gran River is a mammoth, socially progressive nation, ruled by Emperor Arthur with a fair hand, and remarkable for its museums and concert halls, multi-spousal wedding ceremonies, and devotion to social welfare. The compassionate, democratic, cheerful population of 9.279 billion Ipeonics 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, outspoken government juggles the competing demands of Education, Administration, and Industry. It meets to discuss matters of state in the capital city of Arthuropolis. The average income tax rate is 99.4%.

The frighteningly efficient Gaucho economy, worth a remarkable 2,355 trillion pilas 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 significant contributions from Tourism and Book Publishing. Average income is an amazing 253,865 pilas, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Preservative manufacturers are told to put a lid on it, the government is trying to clean up all the rubbish that has washed up on the shores of Bigtopia and Marche Noire, earthquake sirens are a leading cause of hearing loss, and the nation is known abroad mostly for its Parliamentary antics. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Gran River's national animal is the harpy eagle, which soars majestically through the nation's famously clear skies, and its national religion is Ipeonic imperial cult.

Gran River is ranked 5,973^rd in the world and 2^nd in Sky Haven for Highest Average Incomes, with 253,865.95 Standard Monetary Units.
