<Snipped quote by Legend>

We tend to be concerned if there's activity at all. But it can, and usually is, dangerous and needs to be managed before someone incapable of manipulating them gets themselves or others hurt. And that can happen at the smallest level... That said, a number of things could. A highly concentrated presence of an aspect of nature in a place where it isn't natural or forced can spawn elemental energy that then continues to grow as a self perpetuating feedback effect, for example.

The natural elements certainly aren’t rare by any means. And several disciplines channel those forces.
