After forcibly injecting a Class-X mnestic booster with serious side effects, Dr. Marness finally touched the distant past.

- the "real history" that he, no, was forgotten by everyone.

As far back as he can remember, before he joined the Foundation, the first antimemetics unit was a project of the U.S. military.

It ran parallel to the Manhattan Project during World War II, and the people who came into contact with the outside world called themselves "The Wonderful."

Their initial goal was to experiment with advanced propaganda methods, to go beyond physical conflicts, to find a way to break the ideological apparatus, and to completely eliminate the idea of Na (Harmony) Populism itself.

The "Incredible Ones" spent four years tackling theoretical and engineering problems to create an incredible bomb called the antimemetic bomb.

Naturally, they tried out a weapon that was not yet fully understood.

The bomb worked perfectly.

"The bomb wiped itself out, wiped out our successful test explosion, and scattered all the knowledge that had been put together. We simply forgot that we had built this bomb and started all over again. "This is Marness's memory.

Unfortunately, at that time, they did not have the means of mnestic, and they were unable to find the information that was consumed by antimemes.

The Wonders are stuck in a loop, repeating the process of researching theories, making bombs, weapons working, forgetting everything, and then restarting research again.

But these researchers, who are at the forefront of the world, have finally discovered the problem.

- There was a four-year gap in their research process, and they were unable to find any memories or records related to it.

So is there any other explanation?

However, by the time they had put together the bombs again from scratch, the war had come to an end.

Na (Harmony) was defeated by traditional means, and RB fell to the atomic bomb produced by the Manhattan Project.

Antimemetic bombs are no longer useful.

They sealed the second bomb and began to refine the design in preparation for the third.

Fast forward to 1951, when an anomalous memetic cult with an unforgettable nature appeared in the United States, and the Incredible immediately understood its essence, but no response was received to the requests sent to the higher overseers.

- This cult was later named the "Fifth Church" by the Foundation, and the anomaly that caused the nationwide memetic disaster was the most famous work in the "Fifth Church"-related work: SCP-1425-Star Signal.

Eight days after the cult crisis erupted, the secret laboratory of the U.S. military was forcibly expropriated by the Foundation, and they officially became members of the Foundation and reorganized into the Antimemetics Department.

Twenty hours after it was expropriated, a second antimemetic bomb was detonated.

This time the antimemes devoured all the information of that cult.

– including its existence, its philosophy, everything about it.

With a complete explosion, the cult disappeared.

Nobody remembers, no one remembers being involved in this, zero casualties.

Since then, the study of antimemes has been completely launched, with a steady stream of new theories and new results, and new SCPs can be discovered with every technological advance.

Until one day, they found "that".

- The antimemeic that could not be contained by the department: "The Fugitives".

A malicious entity that cannot be observed or remembered.

Coming from outside of human cognition, the moment it is observed, this transcendent being finally turns its attention to the insignificant human beings living on the material plane.

In an attempt to slow its arrival, the Incredible have blown themselves up with antimemetic bombs.

Marness was the only one left to have all memories erased and survived.

No, to put it another way, maybe those who were consumed by antimemes never died.

They were simply "forgotten".

They have always existed, but no one else can see them, remember them, or perceive them.

They became part of the antimeme.

Like an infinite spiral, survivor Marness suddenly came up with the "new" concept of antimemes one day.

Yes, a completely new realm that has not yet been discovered by humans.

Looks wonderful, doesn't it?

Foundation Creation ...... No, the Antimemetics Division has been rebuilt.

The technology of the new era is constantly evolving, and the effectiveness of mnestic enhancement drugs is also improving.

Then one day, Dr. Marness decided to use X-class potions to evoke all the memories he had forgotten.

He finally remembered everything.

At the same time, the "fugitives" returned.

- "The only way to destroy it is to destroy all knowledge associated with it." The easy way to get it back on again is to recover my memory!"

He also remembered this.

Dr. Marness, the founder of the Foundation's Antimemetics Division, eventually followed in the footsteps of his companions.

He made himself one of the Forsaken, as a way to briefly erase the world from the "fugitives".

And then what?

When Marion Wheeler, the last head of the Antimemetics Division, walked into SCP-3125's containment chamber, the most incredible truth was revealed to her again.

SCP-3125 - "The Fugitive", has a critically dangerous Keter rating on file, however its containment chamber is a normal room filled with information, devoid of any anomalies, and devoid of SCPs.

The auto-sensing sensor follows the program to turn on the laptop, and a video starts playing automatically.

The minister sees himself in the video, a woman with a tired, desperate face that does not exist in his memory.

It was her past, the memories she had made in this containment chamber in the past.

Every time you walk out of this room, all memories of the room are erased.

So she doesn't have any impression of it.

"You've guessed that SCP-3125 isn't in this room," she says in the video, "in fact, it's the only room in the world that doesn't have SCP-3125." This is called 'reverse containment'. SCP-3125 has spread throughout reality, except for the areas that are particularly defended against its effects.

"Every effective antimemetic research project will find traces of SCP-3125 sooner or later. It manifests all over the world in more than thousands of forms. Most of them aren't even anomalous. Some have been listed separately in the main database table. Even a small number have been contained.

"Impossible virus cults, destructive arithmetic, invisible spiders as tall as skyscrapers, people born with invisible organs, these are unprocessed data. Dealing with these manifestations is troublesome enough......

"But as you dig further down the road, you see some patterns in the data. You need to be trained in mnestic technology, but once you have the training and the data, it only takes a little effort to place the data points in the conceptual space and draw an outline within them.

"These data points are dotted onto SCP-3125's outer shell; You put four or five different SCPs together in a shape, and you see ...... It sees you, too......

"When that happens, when you have 'visual contact,' it kills you. It will kill you, and then kill everyone it feels like you. Not physically, psychologically. Anyone who thinks the same way, people who have the same state of mind.

"It's going to kill your collaborators, it's going to kill your whole research team, it's going to kill your whole family, it's going to kill your parents and children. You will become a non-existent human being, an empty humanoid shell that surrounds the emptiness of reality. Once completed, your plan will become a hole in the ground, and no one will ever know about SCP-3125 again.

"It's a black hole in antimemetic science, devouring careless researchers, with no information to release, only from indirect observations. A direct description of what SCP-3125 is, or even just an allusion to what it is, will result in a containment breach and a lethal indirect cognitohazard.

"You see? It's a defense mechanism. The act of devouring these messages is just a shell, a toxic coating. It protects that entity from detection when it invades our reality.

"As the years passed, the manifestations continued, becoming more dense and interconnected...... Eventually, the whole world was overwhelmed by them, and everyone could only shout, 'Why didn't anyone find out?' and no one would answer, because all the people who found out were dead and were wiped out by this mechanism......

"Did you see that, Marion?

"Seven years ago, there were more than 400 antimemetic research teams around the world. Government agencies, military branches, private groups, university programs, many are GOIs or GOIs.

"We've had alliances with most of them, and we've been the vanguard of the Antimemetics Alliance, with thousands of people all over the world. Now none of these groups existed, and the last one disappeared within 72 hours.

"Three years ago, there were over four thousand people in the Foundation's Antimemetics Division. Now, there are only ninety people.

"There is no war, we have lost, it's over, it's a post-facto cleanup. The only reason we can still exist is because we are world-leading in amnestic biochemistry.

"Because that's the only thing we can do when we see SCP-3125: run for our lives and forget what you're seeing...... Find forgetfulness in chemical, alcohol, or head trauma. And it doesn't work every time, it's on patrol.

"We saw it again and again without noticing it. There's no way we're not going to find it again! We're so smart!

"We can build a machine. It would take eight years, a lab as big as West Virginia, and all the money in the world. The O5 Council won't blink at our requests. But how can we build it without noticing what it's for? It's like building Apollo 11 and no engineer knew the moon existed. The logistical demands can be insanely large, and it's impossible to keep secrets. There's always someone to ask. And then it all ended.

"So what can we do?"

We are the last in the world, and we will not come again.

The "fugitives" are slipping into known reality, and humanity has nowhere to run.

There have been many antimemetic institutions in the world, and they have all ended up in the realm of "fugitives".

They were all consumed by SCP-3125.

This is the Foundation's last antimemetics unit, where the threat of 3125 will be confronted, and this is the only place where the truth can be known.

Then she suddenly remembered.

The entire department is left alone.

At the lowest level of Site-41, two hundred meters underground, no one cares, no one knows about its existence, and it has to fight against an immortal idea.

Pursued by 3125, she injected herself with a Z-class mnestic potion.

Class-Z mnestics are the ultimate trump card in biochemical memory defense.

Class-Z mnestics permanently destroy the user's ability to forget.

The result is a memory with perfect clarity and perfect immunity to antimemetic effects of all intensities.

She knew everything that was going to happen to her.

She could feel mental reinforcement like steel, and extreme sensory overload was in progress.

She remembered everything.

She could see everything.

Is the idea to kill to death?

Yes, ideas are to kill.

She said to no one alone, "With a better idea." ”

If something can move from conceptual space into reality and take on a physical form, then the reverse is possible.

It is certainly possible to find a physical entity, physically extract the idea it symbolizes, and then expand that idea and broadcast it into the conceptual space.

A bigger idea, a better idea, a concept designed to fight SCP-3125.

An ideal.

One action.

A hero.

The machine she's going to build is an Olympic stadium-caliber machine, and she has no experience with heavy memetic engineering, let alone materials and time.

But she knew—someone had taught her that, she couldn't remember who—that the Antimemetics Department agent was just as good on the first day as he was on a regular day.

The same is true for the sector as a whole.

She said to herself: we won on the day the war began. When we first encountered SCP-3125, we built this bunker.

Bart Hughes, who built Containment Chamber 3125, faked his own death and isolated himself from working here undisturbed, while the rest of the department remained as manpower as possible to buy time for this moment.

She couldn't remember much anymore, and she knew it was what she did because it was what she had to do then.

She is the last part.

But where the bunker should have existed, she found nothing.

Almost nothing.

In the middle of the space is a small outpost, scattered around with a stack of tools and toolboxes.

There is no "right machine" in design.

There is only one hydrogen bomb-level antimemetic bomb, the Antimemetic Department's site nuclear weapon.

Once activated, it will contaminate Site-41 and all people and objects within its antimemetic radiation.

There will be no Site-41 or an Antimemetics Department after that, and the escaped infected will have no real-world effect on what they do.

It is incapable of destroying or containing SCP-3125, or even injuring a single hair.

It can only calm the outbreak for the day, and other symptoms will continue.

Fifty years, ten years, five years, or maybe just a year from now, maybe tomorrow, SCP-3125 will make a comeback with its MK-class apocalyptic scenario.

Human civilization will be erased as an abstract concept and replaced with something unimaginably evil.

Then no one will be able to fight it.

So what?

There is no choice.

This may be the only way to go.

She had lived so long that she had almost forgotten what this universe was......

"For a while, I actually thought, maybe...... It's a universe we can win a few times. ”

Marion Wheeler set off the bomb.

Marion Wheeler saved the world.

Since then, the Foundation has no Site-41, and the Foundation has no Antimemetics Department.
