Acnologia stood at the mouth of a mountain pass in his human form, overlooking the valley of smoldering ashes below him. He had felt the presence of dragons in the area, but had arrived at the village too late to find the dragons. So, to relieve himself of his anger and frustration, he obliterated the village with a single attack.
As he was turning to leave the village, he heard the cry of a small child to the side of him. When he looked over, he saw a child no older than 6 looking at him with shock and fear. Deciding not to waste his time looking at the human, he pointed his finger at the child and shot a blast of magical power strong enough to destroy a building at the kid.
The boy cried out in shock, unable to move away from the blast, and took the shot to his forehead. When the explosion caused by the blast cleared, Acnologia was curious when he saw the boy laying on the ground, still in one peace, and breathing with just a few scratches covering his face.
Taking a better look at the child, he was even further surprised. It was not the fact that the boy had taken so little damage from his attack, any person with enough resistance to magic could have done the same, not was it the fact that he had salmon hair instead of a normal color. It was the fact that the boy had an extremely underwhelming magical aura that nobody should be able to survive with, whether they be a mage or common folk.
Intrigued by his discovery, he walked up to the boy, grabbed him by the collar of his, now tattered, shirt, and held him up to examine his sleeping face closer. Upon closer inspection, he did not find a way for the boy to nullify his magic aura while he slept.
"Interesting," he said. "Yes, very interesting indeed. Perhaps, if I were to teach you magic, that time spent with you will show me how you are able to live without any magic output."
After saying that, Acnologia turned to face the mountain pass and started walking, dragging the boy behind him.
