I wasn't sure how you were going to revive your villain so I left it at that. I guessed Void was going to push a lot of strong negative emotions into him and he would feed off that? So I left him trapped in the school but explained why he couldn't get out.
Sorry for the really short contribution I had an outline then it went poof in my head and I forgot where I was going. I left it open as to whether Dangerous was or wasn't affected by Tempest's powers. The Death Eater could have been real or a result of her unintentional program stemmed by her fear of killing others.

"On a day like today
I looked at you and I
Saw something in the way
You stared into the sky


But I saw you were sick
And tired of my wrong turns
If you only knew the way I feel
I'd really love to tell you"
