Julian Craft explains in the Craft of Enchanting Escalation...

“Within the mystical populous, 

there are five different cultures into which a wizard’s affinity may theoretically fit...

There are the Sorcery whom possess an instinctual spiritual affinity, and 

there are the Magis whom harnesses elemental connections. 

There are the Geni that develop intellectual mastery over the material. 

There are the Elven that have herbal relationships, and 

the Wherdier that have animalistic capabilities.
