I'll go first to sort of, kick things off.
1. Scarlett Duffy, Ilvermorny student
2. She knows how to get letters out because she did it on accident once, but she's kind of awful so she may not share right away.
3. Honestly, she could probably be convinced to work with Gwen and Julian, provided her father (Augustus) doesn't show up or something. She doesn't know he's her dad, so that definitely depends. If not, she's just sort of there and will end up transferring to Hoggies next year for her last year - probably as a Slytherin
1. Declan Arryn, former professor
2. He's on the ground. Rofl.
3. I'm not sure if I want him to be 100%, which can be decided later. But he won't be able to get word back to Oliver, who asked him and Dom to go over there, so they won't realize that the train was found. Maybe this leads to Oliver contacting people about it or someone deciding to just check it out themselves? Dec will also help as much as he can from the other side of the shield re: food and cooking and growing things.
1. Katherine Avery
2. She's just sort of there right now.
3. I'd really like there to be something that requires her to use a great deal of her magic. Since her body rejects it, that will leave her on the edge of death and that opens up personal plotting stuff for me through her brother/family in general. I can make something up whenever, though, if it doesn't fit.
Note: potentially, another portkey would work better than a ferry if Gideon's trapped it there and Domlan continue to be useless. Which they probably will, given their lack of real ability.
1. If the plot continues through the school year, Keiran might go over once they find out the kids are there, to help teach since their profs are gone. But this depends on if the adults find a way to get the kids out.
1. Christian Zabini
2. He's working with Ace Longbottom to find the kids who didn't make it on the train, or who took a floo or portkey home. They want to build the PA so they can go over like they're students to stay or something (plan not yet formed, really) but instead act as spies or help somehow. Either way, they're working on the PA stuff though, and doing so inside Hogwarts because Ace has the map.
Oh. And there's Simon. He's getting out of Azkaban and has just had his memory obscured on accident by Millie. He's working for Khaat's bad guy but doesn't know he is. He does a lot of illegal potions trading and acts as the go-between for people doing sneaky trades. After being accused of murdering a child and spending time in Azkaban previously for that, he hasn't found another job yet. So he may be helpful somewhere, because now his memory is messed up, he can't remember if he did it or not. Even if people tell him they know he's innocent. He could also find out who he works for and want to quit. I'm open to Imperious curses and stuff, though, for him.
