The Republic of Dark Arin is a colossal, efficient nation, notable for its state-planned economy, frequent executions, and irreverence towards religion. The hard-nosed, hard-working, cynical population of 3.371 billion Dark Arinians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The relatively small, pro-business, well-organized government juggles the competing demands of Healthcare, Industry, and Law & Order. It meets to discuss matters of state in the capital city of Merged Realms. Citizens pay a flat income tax of 7.5%.

The all-consuming Dark Arinian economy, worth 331 trillion Broken Dollars a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is broadly diversified, is led by the Arms Manufacturing industry, with major contributions from Information Technology, Woodchip Exports, and Door-to-door Insurance Sales. Average income is 98,479 Broken Dollars, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 544,483 per year while the poor average 8,982, a ratio of 60.6 to 1.

Tombstones are ten feet high to accommodate the names of inhabitants, people are often woken up by rubbish music, parents often leave their kids in the car while they attend mindfulness meditation sessions, and physics lessons mostly involve talking about emotional management techniques. Crime, especially youth-related, is pervasive. Dark Arin's national animal is the Evil Dragon, which teeters on the brink of extinction due to toxic air pollution.

Dark Arin is ranked 315,101^st in the world and 75^th in Shin Godzilla for Nicest Citizens, with 0.56 average smiles per day.
