So an extremely, extremely, EXTREMELY important character has just been introduced. Let me detail how I'd like this scene to go out.
I'd like everyone to reply about their character's reaction to this character, because I think it's a very important moment. I can see two ways to do this; you can have your reactions be private, and not have your character directly interact with her. That's totally fine. However, if you would like to talk to this character, actually have a conversation with her, then please let me know and we'll collab it up. In that case, it'll be a first come first serve basis. If someone will be posting ahead of you I'll let you know that before we start working on the collab, and when the person (or people) before you do post you can see to make sure no one is stepping on any toes.
If you have any questions about this character, be it to get more details about her so that your own characters can have thoughts about her, feel free to ask. I did my best to describe her, but I always feel that with more "fantastic" things I'm afraid I get too vague, even if I think being vague has its own benefit when it comes to the difficult to comprehend.
