The match between two master level mages, Patricia was victorious. It's simply because she has slight advantage in magic control. She learned it earlier than other master level mages.
Magic control is also something that everyone needs to learn. So instead of writing it down on paper, we will send some people to other countries and teach mages over there in how to use magic control.
It's easier than just giving them some notes about it. After all, there are many questions to be asked.
But this is only for later. We still have many things to discuss after this. And I don't think anyone will be able to focus on learning magic control when they have so many questions about the alliance.
And for this mission, Wendy and some agents who taught in universities or introductory school will do it. They will go to other countries and teach mages over there about magic control.
