Necessarius
The secret magical branch of the Anglican Church. Officially named the "Church of Necessary Evil", the organization was started by Puritans who despise the use of magic in England and sought to destroy it by using magic themselves before abandoning their anti-magic stance and supporting magic. Officially, Necessarius is under the authority of the Archbishop of Canterbury but the current leader of Necessarius is also the Archbishop who now controls the Anglican Church. As one of the three magic powers of Britain, Necessarius represent the religious magic community. Necessarius is currently led by the Archbishop of the Anglican Church herself Laura Stuart.
Amakusa Catholic Church
The Amakusa Catholics are a secret order of Japanese warriors. The order was formed during the Edo period when Japan banned Christianity. In order to escape persecution, they merge Shintoism and Buddhism into their Catholic beliefs to hide their religion which led the Amakusas creating a unique fusion of magic. While skilled sorcerers, the Amakusas are also skilled with martial arts and fighting in groups.

Ten years prior to the events of the novels, Queen Elizard had Parliament disbanded after a faction within Parliament tried to sacrifice her daughter Villain for a spell to destroy all of France's military forces. Since that incident, Britain has become an Absolute monarchy under her rule.
Knights of England
An order of magic knights in England. Led by the Knight Commander, the knights have served England since the Crusades and have become the basis of all magic knights over Europe, including the 13th Knights of the Catholic Church and the France's Orléans Knights. As one of the three magic powers of Britain, the Knights represent the magic community within the country's military. The organization has a grudge against Necessarius, whose power has grown equal to the Knights of England, as the Knights find the foundation of Necessarius to be unacceptable.
