Worldbuilding!
Everybody knew that the Carnivores had its blades pointed outwards these days, and that it now only sheathed them in the flesh of actual foes to the Empire. There was still a certain space given them in camp. There was no need to be antagonistic, was there? There were plenty of real enemies to fight, these days.
Liza still felt surprisingly relaxed when the two of them ducked into the set of linked tents that was serving the Carnivores as a command center. It helped that she had a truly guiltless conscience — Well, guiltless with regard to my loyalties, she admitted to herself. Mother Mary knows that I have plenty of sins to remember. It helped a bit more that she was on a mission for the Emperor himself. She might have lingering reservations about the secret police, but she recognized their commitment to the well-being of the Imperium Orci.
That didn’t mean that working with them was safe, but then: Liza had never been really safe once in her life. Why start now?
