Not much is known about Melissa, but she works for the bio corp Graceland for a decade, at least. She might be in her late 30s or early 40s, but she doesn’t talk about it. Although she is qualified to work as a scientist, she manages the first two levels of the secret bunker, that is controlled by Graceland. She has a medical education that allows her to do regular check ups with the personnel. That’s why most people consider her as a nurse. She likes to be in control and is very playful, when she act out her feelings.
