Susan McKenzie, an odd part of the History of Hollow Falls. Her histories of the Basin Falls region would eventually become invaluable to the efforts to stop the destruction of earth. Little did we expect that the author of these histories would take a role in this story. It is unclear how her interaction will affect the mission.
She is an upbeat, relatively normal person. She can't handle too much liquor, she doesn't like to spend the night without her fiancé, and she has a little more anxiety than she may need, but more important than all of this is one simple thing. She is one of the few true coincidental variables in the universe, this gives her a power beyond anything she knows. This gives her the slightest sliver of agency.
