Alright I have the a rough idea that I am considering here and checking it against GM. I want to make a CIA Analyst who is at her core a science fiction/fantasy geek. She reads too many sci-fi novels home alone and [i]thinks[/i] it would be awesome if monsters really did exist. In her spare time she uses CIA resources to collect data on "sightings" and "encounters" much like a conspiracy theorist. No real connection to the occult or real things that go bump in the night. I am torn on what might make her a seemingly ideal recruit, are the PC's going to be together as a group? I don't precisely believe in photographic memory so I rule that out immediately but I do want to present her as naive yet very intelligent. 

Her particular decay naturally, via what I am gathering from the game mechanic, will be that she either becomes truly enamored of the dark places and be a useful character. Or she will be pushed to the breaking point. 

I bought a novel and downloaded the game setting in order to get a fuller understanding of the feel so my apologies if I am not grasping the concept completely yet.
