Mana

About
Mana is what allows humans to use magic and is the essence of every single element. Mana is not infinite and running out of it will lead to certain death. This happens due to the human body having adapted and essentially relying on mana to sustain a healthy life style. Another danger is having too much mana. Just like every other need, too much of it can be a bad thing.

Unlike humans, animals, demons, etc. have been noted to not need mana to preform magic. The scientists of the nations are still trying to figure this mystery out, but don't have much of a starting place.
