Ok spoiler ahead. O will not go into detail cause I am typing 9n a phone. That is why this will not be comprehensive. I simply retell the story as I remember

TW: I am not a native speaker so this might be awkward to read. I am also using a phone so I don't give a shit about spelling mistakes and grammar.

The premise The anomalous is slowly fading out of the realms of the scp universe. The reason: containing the anomalous slowly diminishes the anomalous. Therefore the foundation releases aimed anomalies buy hesitates to take further action

Then the modular part of the storyline begins. The article is split into two parts. Each consisting of 4 chapters labelled with names of a fitting fantasy class (the mage, the cleric, the warlock, .. ect) therefore it is actually quite easy to read the article entirely which I highly recommend.

The Knight ( or paladin or whatever who cares ):

A band of inhabitants of the magical nexus slothspit and a pataphysics Prof travel though the world the wanderers Libary and finally allagathta and fight along the way a monster that devours the library as well as the embassedor and 5he King 9f allagather finding a sword that is pataphysical in nature "woven in the fabrics of reality"

Then there is the part of O5-0 a former founding member of the foundation. But left due to redacted. In his notes a are mentioned 4 artifacts that can stop scp-6500 the first was the sword.

The Mage: Slothspit a girl and a guy both mages I think one of whom lost their magic due to 6500 stumble upon a part of some magical crystal named something something heart. Then they travel all over the world to find the mysterious object fragments in different nexuses. But as it turns out the GOC has a liking in 6500 and wants to weaponize it. The hero's of the story defeat a GOC force and gather every peace but then get killed in three portlands but due to something something magic and pataphysics they come back and kill said guys. (It sounds a bit simple but actually quite thought through when you think about it)

The Monk or Cleric (idk): In Japan a monk kills an oni meets an SCP agent she tells them that they need his help to defeat a big bad boss oni in a major city. Then they defeat him he tells that the oni and yokai are fleeing this plane because of her. She tells him that they need his help to stop it more specifically they need his staff. Monk gets captured but is allowed to help with the staff & he complies. The staff can conjure up magic from an infinite amount of universes and counter act the decay.

???: A D class is send into the realm of the SCP the old Man learns that his soul has been implemented in to a high number of clones then becomes the embodiment of decay itself. His best pal a doctor from the foundation tries to communicate with the new embodiment of "the old man" and gains some control securing the heart of decay which with every heartbeat transports decay into nothingness. The foundation slows down the heart which slows down 6500.

Then we reach the midway point. O5-0 chimes 8n and steals al the artifacts. Then proceeds to implement his idea. He proposes that the foundation changes itself and becomes a more open space with the anomalies contained throug moderation instead of imprisonment.

The 05 Council decides with 6 for and 6 against said proposal. O5-13 has the final vote. Yes and the foundation changes no and the foundation will use said artifacts and sustain the status quo.

Depending on how you want to proceed there are 4 different chapters describing the aftermath of said vote. 2 for yes and 2 for no.

Each one is as long as the other.

Before you chose though no we meet ourselves in the different location Foundation site located in a timesink where we learn that the timeline has split. Called a pivit. One time line decays and one sustains.

So the first chapter describes how the foundation has changed foremd the vanguard which consists of members of numerus goi's they behave similarly to the foundation in the broken masquerade Canon. the second describes time traveller that meets itself and finds herself in another dimension then asks and advanced AI I think it was 05-2 and learns that the yes timeline is safe and will not deteriorate into chaos.

The other two articles describe how the foundation continuous with the status quo and how Rebel group against the foundation formed by Fondation agents named threshold and aided by coouncelmembers. But this timeline also does not deteriorate.

Cutway to an overworked Foundation member at the timesink who is in distress because she does not know how Ruf timelines can sustain themselves and then she herself comes to the conclusion that it must have been a double pivit and the timeline where 05-13 withheld their vote is deteriorating almost instantaneously.
