The Mage's Association (魔術協会, Majutsu Kyōkai?) is an international, self-preservative and self-defense organization formed by practitioners of magecraft for the purpose of controlling, concealing, and developing Magecraft. It is said to transcend nationality and genre of magecraft, but that is in name only. After having existed for many years, it was decided around the Middle Ages by those who foresaw the decline of Magecraft that in order to preserve their power Thaumaturgy should drift apart from society and become a secret known only by a necessary minimum number of people.
