I see... how interesting. And; as I am sure Combeferre would prod me wish such a look, should I fail to ask; is there any quantifying of magic? That is to say, any idea what makes blood magical, or non-magical?

[A smile, encouraging.]

You make perfect sense, yes! Do only certain things have a magical property that can be boosted, or all things? And... on the more dour note, you are right, Proesseur. Dark Magic sounds a horrific thing; surely, it is not taught?
