Remember these questions: Would "magic" still be called "magic" in a modern era? and What is the best way to introduce Superpowers into a world that previously never had them... WITHOUT destabilizing society? Well I have another question regarding these two.
How could I explain a Mage's (or Superhumans) ability to draw energy from the environment In order to cast a spell (or use their powers). For example... Let's say our Mage/Superhuman wants to shoot a baseball sized fireball from their hands, however they don't have enough metabolic energy to cast the spell...
So what they do is that they draw the remaining amount of energy from the environment (the more power you draw from the environment the more your body is damaged and your mind is strained).
So my question is... Is it possible for a magician/superhuman to draw the remaining amount of energy from the environment?
