The Maria's Apostles of Santiago AU is a gargantuan, safe nation, ruled by Mother Superior Madelyn with an even hand, and notable for its triple-decker prams, sprawling nuclear power plants, and compulsory gun ownership. The hard-nosed, hard-working, humorless, devout population of 13.699 billion Apsotles have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The relatively small, corrupt government juggles the competing demands of Industry, Defense, and Education. It meets to discuss matters of state in the capital city of Vault-Tec HQ. The average income tax rate is 39.7%.

The frighteningly efficient Apostolic economy, worth a remarkable 3,358 trillion Bottlecaps a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Arms Manufacturing, Book Publishing, and Tourism. Average income is an amazing 245,144 Bottlecaps, and evenly distributed, with the richest citizens earning only 3.1 times as much as the poorest.

Terrorist videos start by thanking their sponsors, there's no representation without taxation, military equipment stores have a tendency to go up in flames, and hiding wrinkles with make-up is illegal. Crime is totally unknown. Santiago AU's national animal is the Eagle, which teeters on the brink of extinction due to toxic air pollution, and its national religion is Roman Catholicism.

Santiago AU is ranked 279,131^st in the world and 51^st in The Fallout Wasteland for Highest Foreign Aid Spending, scoring -13.04 on the Clooney Contribution Index.
