Any ideas about stating up a Garabonciás. They are Hungarian wizards from folklore that are made, not born. Typically 13 people studied together for 13 years. One died at the culmination of their studying and the rest gained magic powers. Their powers were carried around in spell books. They were incapable of casting magic without their books.

Things Garabonciás are capable of:
Flight
Invisibility
Can see buried treasure
make people fall ill or heal heal them
Able to cause plant life to grow or wither
Curses or blessings of luck
Shapeshifting
Ability to summon and control storms

Most of that is easy enough. The big kicker is that they were able to tame and control dragons, usually using them as mounts. Hungarian mythology has two types of dragons. The Sárkány who are capital D dragons more closely related to the Oriental concept of dragons. The also had the more common animal like dragons. These are the dragons that the Garabonciás are able to control.

For the first bit I am thinking of tying everything to an IoP.

Book of the Garabonciás [?]
Description: The book is an ornate, leather bound book covered in magic symbols
Musts: You must have an aspect related to your possession of this item.
Skills Affected:
Effects:
[-0] Purpose: The book grants a Garabonciás access to his magic. Without it he is incapable of
[-0] It Is What It Is: A magic book of spells
[-0] Unbreakable: The Book can not be destroyed save by a ritual designed to subvert it's nature and purpose
[+1] One-Time Discount: It is a large book but is still just a book so it is not particularly visible
[-1] Wings (allows the Garabonciás to fly. He does not grow actual wings)
[-1] Beast change
[-?] Magic. I am not sure if this is best handled by giving them a flavored version of evocation and thaumaturgy or sponsored magic.

I have no idea how much to charge for the ability to ride dragons. Any suggestions? How about any ideas on their magic?

Thanks
