Syd Chambers grew up on Earth with his human mother and barely remembers his alien father from Denza, who left on a mission when Syd was very young. After leaving Earth, Syd learned the truth of his father₂s disappearance on the planet Ashfall, his father had died protecting a devastating secret about the history between humans and Denzans. Syd is now faced with a choice, free humanity from imprisonment on Earth, which will allow them to come into physical power beyond their wildest dreams; or destroy Earth so that humans never have a chance to enslave, torment, and kill other species again. It has been prophesied that Syd is destined to become a world-killer, but Syd is determined to choose his own fate, and knows there must be another path forward that will honor his father₂s sacrifice.
