I can see the use of a Q10 L3 Techniques tome already...
It is a bad book, but instant basics for all your apprentices
(that is when using divide evenly)
Q8 elements
Q6 mind and body
Q6 herbam and animal
Or of course, more colourful books:
Vim and Magic theory
Mentem and Animal
Ignem and mentem (Of anger and passion)
The list goes on, I have quite a few ideas...
