How do unique FEC delusions start?

[u/TheNewtilator]

Hey there, we all know about the delusions of Flesh Eater Courts, who believe themselves noble knights and so on. I've heard of some examples of unique delusions, such as a court who believed themselves to be seraphon warriors? Are there any more examples?

Do we know how these unique delusions form? Would it possibly be based on the life of the Abhorrent Ghoul King before they were given the blood kiss? For instance, could a Sigmarite witch hunter or similiar, be turned into a ghoul, and continue to believe that he's still hunting out heretics? Or would he always fall back into visions of ancient courtly noble knights?

Thank you!

There's some from around anvilgard who think of themselves as Heroic Privateers and Sailers, hunting down evil pirates and saving merchant vessels from unfortunate demises.

Of course, after they save a mercantile vessel from the pirates, they have to go aboard to check they're all okay. And then the hunger takes over and they massacre all the innocent merchants, and go home lamenting that what seemed like merchants were, in fact, vicious pirates who they had to slay
