Chap 1

Callum was taught about dark magic since young as it was the only magic he could do. He hates that he has to kill beings to get his power so he wishes to learn Prime magic, the pure right way of magic. He knows he's got the heart so he'll try everything in his power to obtain it.

Oh and he's trying to stop a war from the beginning.
