Interesting. So what happens in the classic Warlock example, where some low-level mortal bargains with a demon for Power?
Just because it doesn't technically break the metaphysical law doesn't mean the Wardens aren't going to come lop your head off.
I hardly expect Luccio or Morgan or even Harry to go, "Okay, so technically it was the
demon's magic he used when he murdered that guy, so I guess our hands are tied. Darn."
