The Black Cowl in The Enemy Within
Pretty interesting. Definitely looks like there will be some tzeentch flavor to this adventure. Can't wait to get my hands on it.
With extensive improvisation and rewriting, the GM can name the Black Cowl from a much larger cast of suspects

That really is an unfortunate choice of words (or, to put it bluntly, no sh*t sherlock!). 
Hey, if anybody can do "extensive rewriting", it's us rpg'ers. Can you imagine that being laid on the heads of card gamers? 
..and hopefully the artwork is better than that crap they put into Lure of Power -
