"Oh, do not be so concerned. You should have realized it by now: it is like a blot, a stain. It is ... diluted in your Blood, in your body. And while it is only in small amounts, it hardly troubles you. In fact, it only triggers your Bloodline to work a little harder. And that is beneficial to you, no? But be careful, the Taint grows if you persist, and soon, you will no longer be able to contain it, or deny it. Most seek help before that happens."
