Let's say someone self-inserted me into her position, as a level 10-12 Sorceress or Beguiler in a noble house I don't get along with, about to be sold off and raped by a stranger.
I would almost certainly enchant people too. There's absolutely no way I wouldn't. I'd probably commit theft too.
But there's also no way I would stay there, controlling more and more people as the masquerade got harder and harder to keep together.
Just like her, I would be utterly unable to provide for myself, to travel alone, or even to cook for myself without modern ovens and shops.
However unlike her, I find the idea of actually mind-controlling people forever to be unpalatable. Better to travel and use mind control on many people in small amounts than to stay in one place and effectively enslave people.
- This difference is why I'm wary of her doing something similar again.
All I need to do is get far away, and I'll be safe from this family which will hunt me down and sell me to be raped. Once I get far away, I'll be a stranger in a strange land... But I'll be a stranger with fucking magical powers, which makes me the exact opposite of a beggar. Assuming she's a Sorcerer with terrible spells known, she can still sell her services as a truth-teller (she can make people tell the truth, etc), she can likely disguise herself to evade pursuers and make rumors confusing (Polymorph, Alter Self, Disguise Self, whatever), and she may even have fast travel or self-defense spells.
This whole place is established as inhospitable and terrible, so despite the risks I'd probably travel elsewhere. I have divination spells too, AFAIK, so I'd probably pick a destination based on that.
