OK, so, to explain why the hell I like this so much, I'm gonna do a crit of it. Note that this will involve spoilers, so I would not advise reading it until you realise what's going on.

This also isn't even remotely canon, so yeah.

SPECIAL CONTAINMENT PROCEDURES

[Radiohead's I/O]

Niiiiice. The black and white of the cover is both a) reminiscent of the actual cover for A Moon Shaped Pool and also b) fitting given the repeated mentions of black and white throughout the rest of the piece.

Also: Fractals! Self-repeating imagery will feature a lot, as will the imagery of light trying to reach the darkness but failing.

Controlled observation of SCP-2747 will take place using local computing resources to procedurally generate narratives at varying levels of complexity and nestedness.

Any set of SCPs that involves something like this has to be worth an upvote. Playing with narrative like it's a physical object is a damn intriguing premise, as is the idea that the Foundation is running http://shittyplotgenerator.com with a supercomputer.

In order to increase the observable resolution and range of deeply-nested metafictional manifestations, this watchlist should consist mainly of individuals, groups and organisations whose works tend toward containing metafictional content, such as mise-en-abymes and stories-within-stories.

This is a pretty good bit of buildup and continues the theme of metafiction, as well as continuing the intriguing idea of the Foundation using creative arts as a screen into this fictional dimension.

DESCRIPTION

Description: SCP-2747 is a phenomenon appearing in print and online media whereby platforms dedicated to the discussion of works of fiction begin to mention a nonexistent instance of fictional media.

Foreshadowing. It's also a nice and simple introduction to a great high concept.

however, when questioned under duress, said individuals invariably deny having written the affected material, and deny all existence of the fictitious media mentioned within.

We're getting a sense of this thing's malevolence, although it's pretty understated – imagine having written an entire series about something that doesn't exist and not knowing a single thing about it.

The reason for this is unknown. conforms to pataphysical observations documented in full in Appendix B.

It is the current hypothesis of the SCP-2747 research team that SCP-2747 represents evidence of a naturally-occuring anafabula, or anti-narrative:

inb4 introductory antinarrativics

Seriously, we need more pataphysics skips. While antimemetics explored the destruction of memory, antinarrativics (if that's actually a term now) explores the destruction of creative work, which is an interesting take on the whole concept.

a cluster of interdependent signs, iconography and narremes that, when included to a sufficient extent within a fictional construct, leads to mutual annihilation.

Foreshadowing.

It can effect through layers of metafictional narrative, i.e. a metanarrative containing the anafabula will cease to exist within the narrative, followed by the narrative itself disappearing from our reality.

The use of meta-narratives to watch narratives getting annihilated from existence is actually pretty genius both on the part of the author and the Foundation.

The key identifier of the anafabula is that it invariably represents an in-universe antagonist or anathema in all manifestations of SCP-2747

Makes sense. You'd think that you'd attribute the entire annihilation of your reality to an antagonist.

Due to the metaphysical implications and inherent uncontainability of SCP-2747 as detailed in Appendix B

Foooooreshadowing. Let it never be said you didn't drop hints throughout the piece.

APPENDIX A

Here, I've selected bits and pieces I thought were pretty blatantly foreshadowing – minmin can correct me at any time.

Punta de la espira

a desolate, "black, horned" mountain

The motif of black is used throughout the entire thing as an admittedly rather anvilicious way of symbolising 2747's presence. It makes sense, really: things just falling out of existence, leaving black holes…

Taitaru

one scene features the protagonist physically grappling with the shadows in her apartment

The use of shadows again, symbolising something bad happening to the narrative.

described under the trope entry for "Your Mind Makes It Real" as the manifestation of her creative block

Something bad happened to the narrative alright – she's completely unable to complete it. Again, returning to the theme of narrative within narrative and an inability to complete a narrative.

No Sister of Mine

The game's non-playable characters continuously mention a "coalblack thornbound tome" that, when read from, would enable one to either obtain great power, or unleash a dreadful curse

Again, the symbol of a black book. A cursed narrative…

The Scolipendra Wiki

The Scolipendra Wiki is deduced to be an online collaborative fictional universe belonging to the horror, speculative fiction, and weird fiction genres.

GOOD GOD COULD YOU DROP THAT ANVIL ANY HARDER

This is one of the less subtle pieces of foreshadowing throughout the piece, and it's something I'm not too happy about, but if you didn't get it before, you probably will now.

I/O

"spirals of isolation and inspiration… of feedback loops that resonate into the level of the deeply personal, the trembling core of creative psyche"

Take close note to the "trembling core" that's mentioned here. That's gonna become important later.

Mavigne, Or: A Treatise On The Metaphysics Of Inner Space Travel, And The Kingdom Of Erikaar, Whose Name Is Darkness Made Light, And Further Theological Expositions Thereof

At the beginning of the novel, Maas dreams of a supernatural being that is aware of its nature as a dream-entity and is highly indebted to Maas for bringing it into existence.

A dream-entity, an entity within a fantasy… a narrative, you might say…

It speaks of 6 realms demarcated by thresholds, ranging from the realm of treasure and minerals to an intangible plane of light and sound.

Going from the material to the fictional (light and sound presumably being the light from a video game/book and sound being the Radiohead album).

Beyond these 6 realms lies another threshold, this time one of cold and silence, which is described to be the Earth's core

The core comes up again. It's a "trembling core" alright, and considering how the closer you get to this core, the more "fictional" we're getting, it seems like that this is another mention to whatever the hell 2747 is.

ex lux

From here, the resultant narrative structure cannot adequately be described as simple framing devices or stories-within-stories, as the inner tales eventually begin to intertwine such that later tales shed new light on ones recounted earlier, or themselves link to segments of text earlier on in the narrative after lengthy detours.

YOU MOTHER FUCK

If that isn't a shot of meta to the face, I don't know what is.

At several points, characters attempt to consult the testimony of an absent individual, referred to as the Stranger.

A more subtle bit of foreshadowing, and one that really works for the story.

APPENDIX B

[DATA LOST]

Big spoiler time:

What's the first thing you learn when you sign up as a new member to this site?

THE FOUNDATION ISN'T REAL.

It's 2747 at work again. The narrative within the narrative that got erased was Appendix B, and the narrative that's gonna be erased next?

The SCP file, and with it, the SCP Foundation's universe itself.

Apologies if this got all ramble-y. This is a really, really great piece of fiction and anything that forces me to fridge logic about it to this degree is something I can get behind. A +1 with sprinkles and chocolate sauce.
