There is a wide variety of different magical traditions ranging from tattooed barbarian wizards to hermetic wizards studying in dusty libraries to bardic wizards casting magic through music. While the methods of casting magic differ, the basic principle remains the same. Wizards wield arcane magic by learning and mastering metaphysical laws of the universe using techniques taught from mentor to apprentice for centuries. The majority of wizards in the Third Age are trained by independent solo mentors in one-on-one apprenticships. Most wizards learn their craft via years of study under a mentor and most wizard mentors, regardless of their magical tradition, chooses to train one apprentice at a time, or in rare cases two. Wizards may nobly seek out apprentices they think can strengthen their magical tradition and use their powers wisely or they can select apprentices that they think they can easily manipulate and exploit. A lot of wizards are purely mercenary taking on apprentices with rich parents willing to pay lots of gold to train their sons and daughters in magic. Others are trained by a wizard in a formally recognized feudal covens. In most cases it still boils down to a single wizard apprenticing a single student. The difference is that the apprentice is occasionally tested by her mentors peers and not just her mentor. Covens do this to make sure their would-be members meet minimum standards of excellence in order to preserve the coven's power and reputation. The least common means of a wizard learning his craft is via magic schools. This rare means of magic is becoming more common as many princes have taken to bankrolling magic schools in the hope of leveraging their patronage to gain the loyalty of many wizards at once. Magic schools in Scarterra are not like Hogwartz which averaging eight hundred students at any given time. A typical Scarterran magic school has at most five or six instructors and at most two dozen students at any one time.
