I don't see it either, but it should exist. hermetic magic would work for say, the cult of Pythagora, but there should be a different tradition for the priests and what not. Here is a short version I'm making, you can use or change it as you see fit
Dodekatheonhttp://en.wikipedia.org/wiki/Greek_mythology(Yes I'm that lazy)
Drain Attribute: Willpower + Intuition
(There are god arguments for Charisma, but there are not enough Intuition based traditions, and the Greek tradition greatly extoles the virtues of person knowledge, strength, and power, so it does fit, but feel free to change it if you desire)
Associated Spirits
Combat: Fire
Heath: Water
Detection: Earth
Illusion: Air
Manipulation: Guidance
And thats pretty much it, in the end a tradition is just a drain attribute, spirit types, and flavor text, I just don't have time for flavor text half an hour before work.
