In any case, this easily explains many of Magnostadt's actions; they don't care what happens to non-magicians anywhere, as long as magicians will get stronger and get to the top. So, spreading magical tools around indiscriminately is sensible as it gives powerful means of fighting to magic sensitive people even if they don't have the formal arcane knowledge and skills to defend themselves otherwise. Of course shaking the regimes of the normal people is another benefit.
I'll be really pissed off if this wasn't true history but only something cooked up by al Thamen.
