TO SAVE THE GALAXY, A DEAD HERO MUST RISE AGAIN!
Jonathan Bland is a Decider, empowered by the Emperor himself to deal with the inevitable crises of an empire. In the service of the Empire, he has killed more people than anyone in the history of Humanity, to save a hundred times as many. He died centuries ago, but they reactivate his recorded personality whenever a new threat appears. When the crisis is over, they expect he will meekly return to oblivion.
He has other ideas.
