I'm willing to accept "World of the Blind" and "Evil Dead". But for "Fear and self-loathing"... I don't think being able to control the emotions of others fall within the context of Demonic Magic. 

As for "Invocation of Heavy Metal"... Rock and Roll doesn't really fit in (despite how wacko the world already is, and how badass that would be, it just doesn't in my view). I was thinking that we turn it into a Classical symphony instead. Watch Demonic Knights suddenly summon an Undead orchestra to play music that buffs up the summoner and their allies. They could play music [url=http://www.youtube.com/watch?v=DtKCNJmARF0]like this[/url]. Plus, an Orchestra would fit better with your Nobleman character :)

I'd like to hear what everyone else thinks, though.
