The child Horatio was born on the eastern coast of Italy, under good star-signs and prosperous seasons. The people in his village did not like the child; but they respected him, and more importantly, they respected the wise-woman who took him in to raise him after his mother died in childbirth. Horatio grew up not understanding why everyone avoided him, but he loved his 'grandmother' and he helped her around the village whenever he could. He tended her garden, and helped her gather herbs in the nearby forest.
Despite being born frail and weak, Horatio was bright and interested in Grandomther's work, and begun learning from Grandmother, and the soft-hearted old woman could not say no to her adopted child. She was a member of a circle of wise-women in the nearby villages, folk-healers who brought prosperity to their communities; Many of the folk healers did not like a man being shown some of their womanly secrets, but Horatio's grandmother did not care, and when she discovered that when Horatio aided her in the tending of wounds, the people came healthier faster, she was more insistent on the child learning some of the trade, and he earned some measure of appreciation from the wise-women who spoke with his grandmother - until a Magus of the Order heard about the gifted child.
Horatio is a weak and fragile boy, raised by a kindly old woman who loved him very much. She begun to teach him a few aspects of her healing arts, which helped shape his gift into what it is. His Lesser Purifying Touch can banish infections from wounds, and in his brief time as a folk-healer apprentice, he earned some respect from his grandmother's circle of wisewomen. He can never be one of them, but he's proven he is worth their attention, if not their secrets.
Inspiration came from an Anime. There are lots of ways to go here, I probably would take a second Weak Characteristics, and might take Plagued by Supernatural Entity (angel of mercy), have an angel who distrusts the Order of Hermes trying to turn him to the Church to be a holy magus healer. ANd maybe Noncombatant. He's so gentle....
Would make a good Jerbiton if he was Gently Gifted, but he can't be - Still could be a good Jerbiton though. A Bonisagus, Trianoma maybe. He's pretty much designed to become an Ex Misc healer.
