Magic and casting is reserved to upper classes in high society as a means of keeping the peasants down. Many nobles are strong enchanters. And ships frequently pay for abjurers to help protect their ship while it is at sea. there is only one major school for the learning and teaching of magics within the capitol. Some pirates have taken up to learning magic on their own and can be equally powerful to stand up to the government wizards.

Abjuration and Divination are the only schools with easy access to their supplies/knowledge.
