The Shattering Of Magick

Without any other word, Nasiah activated his ability to see the threads of the world. He dashed towards her and made sure to analyze and inspect her carefully. 

What he found was quite shocking. The threads of Magick were all by her; it was wrapping around her body, tearing it apart. This was something Musa talked about with him a while back. It was known as Evirah, or otherwise: The Shattering.

It was when Magick started to tear apart people when they started to overuse it. Usually, this would happen if the Magick used was under too much strain. 

One's body is akin to a musical instrument; playing the right notes induces music, much like doing the right actions would induce Magick. And like playing music on an instrument, if you strained yourself while inducing Magick, you might break yourself.
