Thanks. I was unable to get back to sleep after she got up, so I took her to work early with a few books. Thought I'd give this a crack before bed.
I came to the conclusion that I kind of only need a stub of an interaction - I didn't need the dwarves to *do* anything with it (unless I could think up something suitably creepy to add to the atmosphere of what I'm trying to do), just produce the message. I was wrong, apparently. I wound up adapting a fragment of a Luck spell from Dwarf Chocolate, turning it instead into a curse that would produce minor bad luck for a little while:
[INTERACTION:CURSE]

[IT_LOCATION:CONTEXT_CREATURE]
[IT_MANUAL_INPUT:target]

[IE_IMMEDIATE]
[SYNDROME]
[SYN_NAME:unlucky]
[CE_SKILL_ROLL_ADJUST:PERC:95:PERC_ON:20:START:0:END:10000]
Since it's not attached to the messages (of which I have several sets for maximum creep-out factor) I can just use the same interaction for different messages.
The syndrome in full as it currently stands (bleeding changed to necrosis in order to not insta-kill the dwarves - will change to bruising. Although I want blood spurting to unnerve the player a little, it wouldn't really do that much to most players of DF.):

I put it right after the USE_MATERIAL_TEMPLATE defining plump helmet wine and it works.

Thanks for the help - I think I've got what I need for the moment. I've only got a couple things left for my project, including creating a devious boss (the aforementioned Exile, who needs to be something *killable* but dangerous to an entire fort's military). If you'd like to suggest any particularly dangerous monsters that you think would be a good jumping-off point, I'm all ears - in about eight hours. Going back to bed and then going off to work when I get up.
