Each type of Magic Spells has to fall under one of the Eight Magic Arcane Schools. A Mage that wishes to learn a specific magic must learn it from the school it fall under. Abjuration, Conjuration, Evocation, Illusion, Necromancy, Divination, Enchantment, and Descriptor. There is a Ninth School of Magic that if a magic does not fall under one of the Eight, then it is said that they fall to the "Universal School" in which only "special people" can learn.
The Nine Schools of Magic
- Some say there is a Tenth School of Magic that houses "Arcane Magic" itself but it is said only one mage knows of it.
