The Colony of Planet Arcadia UNSC is a colossal, socially progressive nation, notable for its ban on automobiles, compulsory military service, and complete absence of social welfare. The hard-nosed, hard-working, democratic population of 2.526 billion Arcadians enjoy a sensible mix of personal and economic freedoms, while the political process is open and the people's right to vote held sacrosanct.

The tiny government juggles the competing demands of Industry, Law & Order, and Environment. It meets to discuss matters of state in the capital city of Abaskun. Citizens pay a flat income tax of 6.1%.

The thriving Arcadian economy, worth 191 trillion Credits a year, is driven almost entirely by the private sector, which is led by the Tourism industry, with major contributions from Gambling, Beef-Based Agriculture, and Woodchip Exports. Average income is 75,785 Credits, with the richest citizens earning 9.6 times as much as the poorest.

'A is for Annulment' is a popular children's song, the nation's infamous rickshaw ambulances often double as hearses, photos of picturesque coastal buildings are set against a backdrop of smokestacks and ship hulls, and Planet Arcadia UNSC's children are widely acknowledged as the most foul-mouthed in the region. Crime is a problem, with the police force struggling against a lack of funding and a high mortality rate. Planet Arcadia UNSC's national animal is the Arcadian Zyrd, which frolics freely in the nation's many lush forests.

Planet Arcadia UNSC is ranked 320,964^th in the world and 5^th in Alliance of Nations and Planets for Largest Manufacturing Sector, scoring zero on the Gooback-Jerbs Productivity Index.
