Lesser Gods — Adrian Howell

Despite his newfound standing in the Guardian faction, psionic destroyer Adrian Howell never imagined himself joining the Knights for actual combat missions. He would have preferred to live in peace, but the psionic war takes no one's preferences into account. And much to his own surprise, Adrian finds himself beginning to enjoy the thrill of the chase - until something goes drastically wrong. Now, even as the Guardians prepare for a major showdown against their primary enemy faction, Adrian finds himself trapped in a world of darkness that is slowly poisoning his heart and mind... drawing him ever closer to becoming the very monster he had set out to kill.
