That name is already taken by a school in Pigswig. It is the equivalent of Myth school and unless, for some reason, they (KI) forget they made it this wont happen. Also we kinda have what I would imagine this school doing already in shadow magic and Storm.
Shadow with its backlash Storm with its spells like healing current, wildbolt and insane bolt
Interesting idea but already taken in a number of ways unfortunately
