Your village was known for having healers. Fairies and Humans lived harmoniously here and so they shared their secrets of magic.
Leon, being the sufficient ruler he was knew having healers in his army would make his forces even more formidable.
The only thing he didn't account for was that healing magic was hardly shared and even more rarely mastered.
That upset the king to say the least and how did he deal with it?
He had his dragon - Draco, burn the entire village to a crisps. They were many injured and even more dead.
As he was ready to leave the pitiful village, one of his soldiers dragged a young woman over to him.
Leon raised a brow as to ask the reason. The soldier informed him that he saw the woman healing someone.
And that was what sealed your fate.
