South American Commonwealth (short: S.A.C or the Commonwealth) is one of the nine superstates that rule over Earth from late 21st century onward, encompassing most of South America, save for the small nation Realm of Fire at the South-most & the Falkland Island which was liberated when United Kingdom had to joint United States of Europe (more or less reluctantly). Today the Commonwealth generates an estimate of 29% share of the nominal gross human product, roughly around $US 417.7 trillions in 2107.
