Well, everyone started with their own introductory posts and I've been replying to them relatively individually. If you you're interested in interacting with a certain character, you can PM them. You can PM me if you have an idea but want help brainstorming. This story is really run by the players and is generally sandboxy. 
But you could start by describing where she is and what she's doing/planning in the immediate future and will go from there. Just a post to get a feel for the character and the setting.
