You're very welcome, I've always appreciated the people who've recorded Jim and Brandon Sanderson's Q&As and I figured it was my turn to contribute as he came to my town :)
My pleasure, by the way, it looks like someone filmed his Q&A at Lexington, KY. Here's a link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Df_3c02lelg.html
I I think if I were to have been able to ask a question I would have asked if Harry were to end up as the next Merlin of the white counsel of wizards in the future
I disagree with Jim about Harry's second choice. He'd give himself to the fallen before he sacrificed a good chunk of Chicago's population for necromantic power.
Jason Brough I'm pretty sure that Harry would find a way to pull off a Dark Hallow without killing anyone living. The people dieing near one is the result of a the ritual, not the source of it's power. The power bestowed on the caster of the ritual comes from the spirits of the dead it consumes. I can see Harry going back to Chicken Pizza (spelling intended) and gathering up the spirits there or to some ancient burial ground in the middle of nowhere. Remember that he already used necromancy once while managing not to break one of the laws when he raised Sue the T-Rex, I can totally see him trying to follow the spirit while breaking the word of the law if he felt he had to, to save his daughter.
Matt Cannon The Halloween thing was so that Cowl could take the Erlking's power. Halloween guaranteed that he'd be present, as well as mortal. Halloween isn't necessary to perform the ritual however.
