Another quick question, is there any way to protect people with magic potential that you have invited to your court when playing in the Empire? Expelling the witch hunters doesnt seem to work. As the top liege, i should be able to forbid action against an individual, or atleast be notified when someone wants to kill that person instead of only recieving the "was executed" message.
No. If you have magic in the empire, you're going to have a bad time.
