Ripley and Zoe are survivors in a world burned to ashes by the spacefaring Dragoon Swarm. Together with an alien child they rescued, they fight tooth and claw to secure food and water, and evade the toxic fumes that begin to fill the sky.
A Dragoon Hunter named Braxe Axel has come to the aide of Ripley and her crew. Besides giving the alien girl a new name, he invites them all to barter at a fortified haven known as "Oasis".
