((Grandmother, see this post. And I'm sadly Dresden Files ignorant.))
"Ahh, you wish to bargain with me? You ask me what I would trade to know what drives you. Unfortunately for you, that is not how I bargain. You need to tell me what you need, and I will get it for you and name your price. But do not seek to turn this into a tedious legalistic endeavor. That happened here and I gave the magi here exactly what they asked for and no more. Oh, I knew what they wished for, to be sure. But they sought to bargain with me meanly, and so it became a mean bargain. No, my question of you, child, was what drives you. You may be a maga, but you are in my domain, and do not forget that I am lord here. I have kept many powerful magi here against their will, and even Somnifer, with his power to penetrate your Order's most vaunted protections is unable to stand against me." Candidus appears to stare, as much as someone without eyes can stare, intently into Viscaria when he speaks of Somnifer and his ability to penetrate protections.
