European Union

The European Union (EU for short) is a politico-economic union consisting of various countries in Europe.

Background
For some time prior to the events of the British Halloween, the Roman Catholic Church manipulated the member countries of the EU council, into making "attacks" on the United Kingdom, starting with a treaty that banned the UK's nuclear weapons and required them to give up their nuclear arsenal to France, with the official reason being so that France would be the sole possessor of nuclear weapons in the EU and therefore have the technology to safely disassemble them. With Queen Elizard's reasoning that they need not react to such clear provocation, the other countries continued to take them lightly and act as they pleased, which contributed to Carissa's decision to carry out a coup d'état.

During the Crowley's Hazard invasion of the United Kingdom, Aleister Crowley remarked that if he gathered all of the assets he had hidden around the world, he could probably buy up the entire EU after it had declined following the back-to-back conflicts of the British Halloween, World War III and the Magic God Siege in Denmark.
