This explanation is in no way coined as fact, rather an assumption based on given information regarding yet another set of labels.
Im speaking of the four schools, or classes of magic, which self-classify as follows;
Star: Utilizes planetary energies for works. This ranges from Horoscopes, to Solomons key, (which also use the next school)
The rune associated with this class is Perthro.
Mancy: Works are supplemented and/or geared to commune with beings which lack physical counterpart. This includes mediumship and some higher magics. The rune for this class is Sowilo.
Namer: This class must be careful to think before they speak, in order to keep adverse things from being spoken into being. They also can tell truth from falses, and tend to have a knack for math/logic or numerology. This class is associated with the rune Ansuz.
Elementer: One of this class often enjoys, and their energies thrive, in nature. They may use raw energies from any element, to help power their spells, or heal living things. They are also usually versed in herb knowledge. Rune = Hagalaz
These schools are not be all end all. It is normal for one to pass through each class(at different rates), throughout ones life. Whats more, it is also common for one to be versed in many schools. It is also common for one to be well versed or even adept at one or two. Yet and still, there is always a balance.
In my studies, i often use runes, tarot, and the chakra to describe energetic associations. If ever you feel i have misplsced a description, please let me know.
