Does anybody happen to know where I can find information on these babies?

I dunno - but you should pay for it with a spell check.

P.S. I know, I know - but I'm really tired.

It's probably the same deal as weapon/armor permits -- you basically have to prove you need to have it to do your job, or you need to bribe someone alot of money, or hire a decent forger. Except that with spell permits, I'm sure your astral signiture needs to be 'known.'
