A brave, 15-year-old girl, Ellie has grown up in this harsh world and it is all she has ever known. She’s an orphan who was raised in a boarding school run by the military within the bounds of the quarantine zone. Naïve and curious about the outside world, she is wise beyond her years and highly capable of taking care of herself and those around her. Obsessed with comic books, CDs, and other pop culture, her knowledge base is filled by the remnants of a world that no longer exists.
