As a writer of fantasy, one must learn to understand how magic works and the different theories of its use. If you let the characters in your book or short story run around inventing magic out of thin air, their power will be completely boundless and it will become incredibly unrealistic, because, as we all know; people have unlimited wants but limited resources. If this economic rule does not apply to magic, then… I don’t even want to think about life if economic rules didn’t apply.
Here are a few theories of magic that I have created or heard of from various sources.
I’m naming this theory of magic off of the element of magic used in my own novel, The Fantastical Journey of Gavryn Wickert. In this version of magic, it is an element in the air that can be taken in by the user. Anyone can use it; there is no special blood or ancestry required, but it takes practice. Once someone is used to letting in the element, they then practice expending it by fire and ice and whatnot. So, I guess you could say the enzonic theory of magic acts as if enzone is a blank element that can be turned into something. However, it cannot only be turned into elements but can also be used to look into someone’s mind or lift objects without touching hem.
This idea of magic is demonstrated in the Eragon books, where magic comes from within and uses up inner strength. This is how the author keeps it from going out of control while giving his characters extra abilities.
In many books, the theory of magic is simply the idea that magical things can be attained via scientific intel. Instead of it being an unexplainable mystery, it is a thought-out process.
If you have another theory you’re thinking of, please comment and share it!
