This is why only humans can be high-level Magic Users, and why all Magic Users are Chaotic.
(I think this is now canon for the Desolate North.)
Not all humans are like this. I want a slightly more serious game than that. But despite the fact that they're all squirreled away in towers doing research and pretending to be hermetic and wise, this is how magic works. Which explains why not everyone of a certain IQ can grasp magic - you have to be born with the particular reality-bending "Fuck it, maybe this'll work" twist in your soul - and it explains how so many ill-adjusted magical nerds end up in adventuring parties. You certainly don't see the more well-adjusted and academically-grounded sages bumming across the world with murder-hobos.
