Magic
There was a time when magic was the the specialty of humans and all humans could use magic, back before the bloods of the tribes were mixed. Now magical ability appears rarely among the people of Abeth. It is not any more common among humans than among those who display traits from the other tribes. It's common for magical abilities to remain dormant for years before manifesting suddenly in a moment of stress.
Many people who have a magical ability are self taught, but formal training is the quickest way to achieve mastery. There are two organizations that offer formal magical training, The Church and the Royal Academy.
The Church
The Church of the Ancestor is the most prestigious educational institution in The Empire. While there are several convents and seminaries throughout the empire where the rich can send their children for a general education, only Saint Olaf's Monastery and The Convent of Sweet Mercy are permitted to teach magical arts. The emperor doesn't trust any institution further from his seat of power to teach such dangerous skills.
The Church is best known for magics dealing with healing, light, shadow, death, and knowledge. Even so, any magical talent can be cultivated by the initiates and novices.
It's mostly nobles and rich merchants who can afford the cost of a religious education, but exceptions are frequently made for children who demonstrate enough potential and occasionally for orphans who have no other recourse.
The Royal Academy
The Academy in Verity studies and teaches elemental magic and magic with military applications. Because tuition at the Academy is more affordable, the halls of the academy are filled with the children of artisans and middle class citizens of the empire. Scholarships are extended to those who don't have the ability to pay, but they must agree to repay the school with a period of indenture equal in duration to their education.
Folk Traditions
For someoneThose living outside of cities are frequently apprenticed to thea village witch doctor or some other elder who can guide them. These people frequently use spells in ways that surprise mages with a traditional education.
