You appeal to the dark powers in your own way, demanding a proper audience instead of having them sneak around and eat your people like barbaric night creatures.

And while it does take you a bit to try and persuade the darkness, something does take notice! Specifically, the two operatives you lost, who return bearing their now-extinguished lanterns, and also the familiar livery-clad shape of one of the castle servants.
Of course, all three of them look far worse for wear. In fact, they look barely humanoid, all broken bones and shattered spines and twisted faces with blank white eyes, grinning evilly at you and your compatriots as they brandish menacing claws.
You have sssuch deliciousss fleeeesssssh, one of your former operatives gurgles, sssso muchhh potential... sssurely there isss no problem, it grins a little wider with a mouth full of sharp and terrible teeth, its skin seemingly melted by proximity to whatever horrible force is powering their bodies.
You have their... attention, the servant's mutilated shape says in a clearly mocking tone. What is it that the mortal could possibly hope to offer, more valuable than her body? It ssshould be noted, another says with a shit-eating grin, that your posssition is... tenuous.
A) An operative or three will offer their will to resist, and they can have them without a fight and walk out of here to wreak their narratives upon the world at large.
B) Promise to carry all three of them within yourself, to provide a favor each at a time of their choosing.
C) Offer all three of them lucrative positions in Ortfast's premier spying operation. The pay's very good and you could definitely see yourself finding a lot of productive work for them.
D) Distract them with a more puzzling proposal while you position your operatives to strike at them.
