@fetusdeletus erm, more like a accidental freak of nature tbh, like the chapter covered, vampires are beings born from a magic source
and it just so happens that cyril (probably) casted a huge spell and the residue from that formed into a magic source
this is too sweet I'm puking rainbows.
I give 867 on the Werner-Thompkins-Hong saccharin scale, just a few points shy of 'not fit for human consumption'
