Chapter 5.13
Magic, or magic spells is a supernatural power to bend the laws of nature. It could be cast by converting the source, which is mana, and performing either one of the 'three keys', which are the catalyst for it.
Before talking about the 'three keys', let's talk about mana.
To begin with, what is mana?
It's a form of energy that could be converted into magic spells— but only by performing either one of the 'three keys' could convert mana into magic.
Mana was stored inside your body— the mana core. Like how unique it was in everybody's Deoxyribonucleic acid (DNA), fingerprints, and even their genetic and cultural traits, everyone was born with a different mana capacity, density and wavelength from each other; there may be similarities, but not the same. Just the mana capacity itself is rather distinct when you compare human's mana capacity (the lowest) with the elves (one of the highest).
