that wouldn't really matter, now would it? I mean, sure it would terrify him, but as soon as he got killed he'd be right back. Oh also, you'd have to convince him to go to Solstheim, since the Books only work there
"Do you get to Solstheim very much? Oh, what am I saying -- of course you don't." --- Please assume the position.
Run him through with my sword, go with his corpse to the Cloud District, crucify him in the name of Caesar and then (for good measure) stuff him in the Jarl's backside where he can usually be found these days.
