Well, not quite like that.
I'm reluctant to start messing with a sandbox set-up before getting a sounding on the idea itself. Apologies; I'm not as brief as I could be. I'd link to my draft in google docs, but I'm not sure how that would go over, here. Here's the gist:
Stage 1. SCP appears as a mole on the surface of the skin— usually in some place obscured from the host's view (without a mirror and some craning around). It is not irregularly shaped or colored, and there is no initial feeling of discomfort. After a few days, the host will start exhibiting tics— nothing abnormal, for a stressful environment. There will be a compulsion to touch the skin, especially the neck; the subject might imagine impending cuts or insects stings, and swat or protectively cover exposed areas.
Stage 2. Around nine days after infection, pores start widening; initially symptoms are similar to any number of common skin conditions. Eventually, especially in places where skin is stretches tight (over the back, when you hunch— over the sides of the neck, when you stretch), fissures would start splitting and eventually spreading to every epidermal area. A person’s own motions and movements would perpetuate the deterioration, essentially, the way itching inflames a sore. The skin all over the body seems to be shedding/falling apart.
Notes. This degeneration would not be accompanied by the same kind of intense pain you’d expect, from losing skin tissue, at all. I’d like to convey the sensation in interviews, mostly— and the final stage I’ll withhold, as I think it will hinge most on the experimental log and how it’s written. That bit is intended to be more psychological, and to separate the SCP from just being a particularly horrific twist from mother nature.
The “bacteria” itself (only visible in the “mole” manifestation, not as an anomaly in the blood or anything microscopic) would be transmitted from person to person in a pneumonic plague kind of way— but instead of saliva/ any kind of biological matter, experimentation leads to the theory that it’s spread by certain spoken words.
Decidedly grey experimentation, yadda yadda…. conclusions withheld. After reading SCP's for hours, I'm starting to think that the creepiest are really determined less by idea, and more how they are written— especially the experiment logs. So this is just the surface of the balance I'd like to strike between said/unsaid, described/imagined.
Thoughts and/or merciless criticism would be greatly appreciated.
