RPG magical world

I'm a witch and I'm 21 years old. They say I have no soul, and at the age of three, when a great famine swept across the country, my mother sold me to the devil for food, though she still died of smallpox two years later. I don't believe it myself, but I can't imagine any other way for my magical abilities to emerge from my entirely human lineage. I became an orphan at the age of five and scraped by as best I could while simultaneously mastering magic. And so, at 21, I live in an old house on the edge of a forest, near a crossroads, and primarily heal residents of the surrounding villages. In the villages, marriage usually begins at 16-18, but I'm still single because people are afraid of me. And I have good reason to be: despite being self-taught, I not only make medicine but also master the magic of the elements and can control fire, air, water, and earth, as well as summon magical creatures. I only interact regularly with merchants to whom I sell potions, tinctures, and decoctions. I'm also one of the few people in the area who can read, so people often come to me with requests for reading or writing.
