He could hear voices whispering and screaming inside his skull, a babble of madness that would have swamped a lesser man's mind. But the mind of a Grey Knight was built around a hard core of pure, depthless faith. Where other men had fear, the Grey Knights had resolve. Where others had doubt, Mandulis had faith.

"The only man?" scoffed Proton. "What about all the other lazy sods? There are six and a half billion people on this planet!"
