So I have a couple of characters I could potentially throw at either of yours.
Hella, my Fae-touched ex-necromancer could work with either Natasha or Tomas. She's interested in reacquiring some of her magic, but is generally disinterested in learning it at the school. She doesn't care for the structured setting and kind of wants to learn magic on her own terms, in her own way.
Likewise, she has a magic tattoo that mimics the effect of the Fae magic that turned her into a girl (she's mtf transgender), and had to take out a loan with someone because that was an expensive thing to get. I'm not 100% sold on the idea of her owing money to a predatory loan shark, but I'd be willing to talk it out at least. At the very least she would defimdefin be careful about reading a contract with him if she did do that.
My other character would really work better with Tomas. Fitz is a conman who is looking to get into the smuggling business. More organized crime. And to that end, he's trying to build up a network of contacts. A safety net, as it were. Fitz isn't actually magical at all, but he pretends as such and he's hoping that if he surrounds himself with enough magical people he can compensate for that.
Let me know what you think. I'm easier to contact on Discord than the forum, but I can do either.
