So the new character I am coming up with (we'll talk later...) may be someone you'd consider. If she's freeborn, possibly an estranged relationship where he keeps an eye on her and such, if she's a helot maybe he even owns her and sorta lets her do her own thing because he knows she can't focus.
My guy will be a friend of Mads & Ladera, he works for the gov and does fang removal (legally) and only occasionally dabbles in darker means.
