Many of the lands are controlled by two violent leaders: Warlord and Druglord. When unable to find a way safely through their territories, Prince forms an alliance with Ash, the last synthetic to survive the holocaust and an assassin robot forced to serve Warlord. Ash discovers that her purpose was once more than slavery and that she might be the only person who can save humanity from itself.
