So I was reading my WH codex the other day and in the bit about Karamazov it tells the story of him arresting, torturing and executing a popular preacher while ignoring repeated demands from the Ecclesiarch to stop. Supposedly the ecclesiarchy now seriously has it in for the little man in the big angry chair.
This got me thinking, what would have happened if Karamazov had requested some sisters to fulfill their oath as the chamber militant, and the preacher had also called them to his aid? Or what happens any time a Hereticus Inquisitor calls on his or her chamber militant when they want to, you know, arrest well-armed heretics within the ecclesiarchy? The sisters have sworn an oath to the Ordo Hereticus, but they are also the defenders of the faith and I'm pretty sure it's been established in fluff that they serve as bodyguards for Cardinals and pilgrims and guards for cathedrals. Fluff seems to be full of corrupt priests, they seem to be a major target for the OH. Does this mean sisters fighting sisters happens a lot?
Seems to me these responsibilities would quite often put the sisters in a bit of a pickle...
