Fangyr,
Have a question for you, who would you tell if you had magic? I do not think I would trust to many people with this secret, and would feel like the Salem witch hunt would show up and burn me at the stake. Unless you could get the protection from a king/queen/duke/duchess, I would be worried who to trust with this information and would my family be in danger?
I heard them mention fireballs from the sky in a Q&A, but nothing on how strong that would be.
