Nacht und Nebel was a directive issued by Adolf Hitler to, essentialy, target persons of interest and anyone even suspected of not having Germany's "best interests" at heart, and make them disappear. The aim was to instill a sense of fear and mystery in the populace by never revealing the true fates of those they had taken to their families and friends, whether they had been killed or were still alive, so as to keep the oppressed subservient. German for "Night and Fog", taken from Richard Wagner's work Das Rheingold, the directive was responsible for the complete and utter disappearances of countless detractors and innocent people, who were never found even after WW2 ended and concentration camps were liberated. The Nazis even coined a new term for those who "vanished" in accordance with this decree; they were vernebelt—"transformed into mist" (seriosuly). Wilhelm Keitel, who issues the directive, later testified that out of all the illegal orders he had carried out, Nacht und Nebel "was the worst".

Now, Keitel's Baton has summoned spectres of mist, and the sheer amount has created a thick cloud of fog around the Warehouse... and that's about all I've got. How it activated, or why the fog is specifically outside the Warehouse, I'm not solidly sure of yet. I've considered the idea that, as they're (I imagine) the spectres of people the directive disappeared, they're bound to manifest just outside of inhabited areas, out of view in limbo as they were in life. To deactivate the baton, I imagine someone may need to somehow give them identity, some sort of acknowledgement?

I considered the idea that the baton specifically manifests foggy apparitions of those who died in the vicinity it was activated in (which in this case would be quite a number of Warehouse agents), but since those people were known in life and for the most part identified in death/had their bodies found, I'm not sure that would work with the baton's origins, unless that effect was deamed satisfactory. In the latter case, simply figuring out who each spectre is, with or without an artifact, could suffice (and could be made into a log).
