Harrith sighs, shaking his head. He turns to the Lord of War first.
"Unfortunately, I doubt that the threat is fabricated. Why would the Inquisition do so? They would have to expect that the Emperor would carry out his own investigations before sanctioning any overt action, and any such fabrication would be quite easily exposed, especially if His Holy Highness has any agents or contacts of his own with access to the organisation. No, while it is possible that they have exaggerated the threat, either purposefully or through bias, I doubt that they have simply invented the situation out of thin air. It would gain them little to nothing, and cost them much."
Following this, he turns to the Shadow of the Emperor.
"I do not dispute that the Emperor's goodwill has been the reason for their continued survival, but I also doubt the Inquisition were particularly careful about verifying whether any given non-human they found was a member of Samael, and it would not be entirely surprising to learn that some of the more... independent... members of the Inquisition took their own clandestine action on the matter. That they survived any such threats with an intact organisation indicates both that they have experience dealing with being hunted by Imperial forces, and that they are capable of applying that experience practically."
"Given the situation, and the seriousness of the possibility of an escalating threat from the supernatural, I for one will be ensuring that the lands in my charge are assigned increased numbers of troops trained to hunt and eliminate the supernatural, as well as thoroughly vetting their command structure; While I would not presume to tell either of you how to govern your own charges, I would suggest that you take great caution in doing the same;" an amused tone enters his voice here, "After all, the old powers can be insidious, and the Principalities do love their little games of power and independence."
"On that note, I will be doing what I can to... discourage the usual politicking, or at least turn it to more productive ends; I would ask that you do the same where possible, particularly on the border regions; When a potential threat of this magnitude arises, requiring a personal command from the Emperor to all four Lords, it behooves the Empire to stand together and... set the usual jockying for influence aside."
He accompanies his last words with what would probably be a measured, meaningful look at each of the other Lords of War, if he wasn't wearing a full helmet with a mask.
"Well. Anything else to cover, Lords?"
