First, while it's fine to be inspired by something in the real world, or to incorporate pseudo-historical/real world ties to a skip; making an actual group of real-world people into a magic sex cult is incredibly tacky.
Second, this meanders on for far, far too long- covering a ton of points that are already well-worn by now for this GOI- with nothing ultimately to show for it. I feel like I've read most of this already in other Sarkick articles, and what isn't already tired repetition is simply introduced and forgotten just as fast.
Agent ██████ is to infiltrate SCP-XXXX via initiating a romantic relationship with an instance of SCP-XXXX-1
This struck me as a bit unnecessary at first, which was confirmed when absolutely nothing comes of this procedure. It's just thrown out there for squick, with no baring on the narrative proper.
On further reading, this does seem to come into play, so maybe fix that blackbox to give Balogh's name? At any rate, nothing special happens here (first collapsible) that I'm not already expecting, just…more of the same.
MTF Sigma-3 “Bibliographers”…are prohibited from accessing this file.
Here as well. Introduced and then….nothing. This seems name-droppy, as there doesn't seem to be a point to their inclusion, as they never show up again and any made-up MTF would fit in its place. Why would they be prohibited from the file? I couldn't tell, and that's a problem.
A quick footnote or link here would have been nice. Not everyone knows what this is.
Description is well written, if entirely ho-hum due to being overly typical. Nothing here stood out as particularly interesting, and it was pretty standard-fare Sarkick shtick. I lost interest quite early, but decided to press on, hoping for a payoff.
Note: There's some areas where it seems like you're trying to establish this outside of typical Sarkickism, but they rest if the description reinforces that they're about as Sarkick as blood-apple-pie, so its a waste of words in the end. Telling us they're different isn't enough when you show them to functionally be the same.
The exploration log is similarly well-crafted (structurally, that is, though you could use linebreaks between the dialogue), but just…ends. I don't feel like I learned anything, I certainly didn't feel anything…it just felt directionless.
Despite all this, I feel like this has a chance to survive (it may struggle due to the aforementioned points), though I'd definitely have to downvote as-is.
