On a tip from Ivor, Jesse and friends head to an abandoned temple holding mysterious treasures. Ambushed by former Ocelot Aiden and his crew, our heroes find themselves in an entirely new world: Sky City! As they explore, the Order finds that resources are at a premium, and nothing but 'The Void' exists below the known world. When Aiden convinces Sky City's ruler that the New Order of the Stone are up to no good, you'll need to make some tough choices to clear your name, and keep Aiden from destroying an innocent world.
