8Sergeant Davida Uri is the only volunteer willing to locate a missing group of people simply called the Survivors by the lethargic group of World Leaders that run Shamayim, a city designed to shelter civilians that have already been rescued. As Sergeant Uri journeys through this new wasteland, she runs into a reluctant and hostile academy, a group of beings known as the "Caretakers," who have taken on the task of restoring the Earth, as well as a being Uri simply refers to as the Shadow, when she is unable to make out its features throughout most of her journey.
