I watched a world die. Eight thousand years of defiance, gone in an eyeblink. With it, went some of the finest soldiers I had the honour to serve alongside. Not for glory. Not for victory. Not even for defiance. But because sooner or later the void swallows everything. I learned something that day: no world, no bastion - maybe no faith - is impregnable. The agents of the enemy are everywhere. Watching. Plotting. Waiting. Only thing to be done with heresy is to root it out with fire and steel.
