In a kingdom far, far away lived three mages. The eldest mage the smartest, the youngest the strongest, and the middle mage was the fastest. The mages lived in one house in the forest. One day they stumbled upon a child who seemed gifted in magic. The youngest and eldest mage voted to keep the child and train it in magic, but the middle mage voted to find the child's parents in the nearby kingdom. So they choose to keep the child. When the child awoke from their slumber, he followed the mages when told to do so.
That is when they began his magical training; They started with teaching the child simple spells, but when they saw his ability they were amazed with his destructive power and began to teach him more powerful spells that the child took only mere days to master. In only a few weeks the child had surpassed all three mages in turns of power knowledge and speed. It was all going wonderfully until an army of demons sensed the presence of a new high power magic source and knew one way or another it had to be destroyed or brought to their side.
So in the middle of the night, the army approached the house and set it ablaze. The mages and the child rushed out the burning house, but little did they know what would happen next. A dragon swooped down, blowing the mages away with its wings before the grabbing the child in its claws and flying off. Once the dragon reached the demon's territory, it threw the child into the demon king's throne room. The spiritual pressure of the demon king forced the child to the ground when he tried to stand there, the demon king tried to use his powers to convert the child to a demon but due to the child's pure heart he failed. This was the child's chance to fight back, but he was too scared to cast any spells, but even if he could, it was already too late. The demon king who was enraged by the fact that he couldn't convert the child used a blade of pure flame to stab the child through the heart.
