I can actually. If the magics of that era were so dangerous, why would the Elements ever allow mortals to have access to it again? They grant power over White Magic to the Padjals, the aforementioned, 'Privileged Caste,' they created to rule over Gridania. It's entirely cult-like behavior and brainwashing. It's only viewed as acceptable because the Elements are seen as something greater than mortals, rather than just a different kind of lifeform.
