Various schools exist that educate young mages. The goal of these schools is to:
1: Install a code of ethics into future mages.
2: Teach how to safely use magic.
3: Share knowledge on magic.
4: Create connections and bonds between the future mages.
5: To keep track of potential troublemakers.
Vatican and the Catholic Church: The Catholic Church is the biggest magical organisation in the world. Long active for hundreds of years, it is a religious hub for mages and non-mages alike. The Catholic Church has two goals:
1: To find solid proof of the Holy Trinity and Heaven.
2:To install morals into humanity, and protect the greater good.
Private Organisations: Many private organisations exist for atheistic mages to safely learn the magic arts. Perhaps a government or company. These organisations usually have a hidden agenda, whether it be good or bad.
Cults: Religions other than Christianity that teach their followers magic and the way of their gods. Many cults exist that worship the Demons.
Familial Schools: Private families will sometimes not allow their young mages to attend magical schools, and instead teach them everything they know privately.
