SCP-3984
rating: +159+x

The library is warm and dark. Outside, it is a summer night — warmth and humidity lingers in the air from earlier in the day. A storm is predicted for the week ahead, but the sky is clear for now. The library has been closed for several hours, and there shouldn’t be anyone around until morning.

You shut the front door quietly behind you and make your way out of the foyer. The floor is a carpet, soft and thick, muffling each of your footsteps for you. Security cameras, their gaze trained upon the door through which you just entered, are blind. You cut their power half an hour ago. You can never be too safe.

A wooden door leads from the foyer into the library proper. You know that it won’t creak when you open it because one of the maintenance workers oiled it a week ago. That maintenance worker was you. You don’t work here. The door swings open smoothly without so much as a groan.

The carpet continues into the library’s main room, blue in most places, but a yellow path weaving its way between shelves of books towards the librarians’ desk. You start to follow it.

A stray book lies on the floor, shrouded in the darkness. Your foot hits it. You trip — not enough to fall, but enough to throw you off your balance. You reach out and grab a bookshelf. Your hand, searching for a place to grasp, hits another book and sends it falling to the floor where it hits the carpet with a thud that echoes all around the room.

You freeze. The echo fades. The library returns to silence. If someone were here, they definitely would have noticed that. Hopefully, they would have come out to say hello. You decide that you are alone, and continue walking.

You arrive at the librarians’ desk and, somewhat awkwardly, climb over the counter. Behind, you take a seat at one of the two computers and boot it up. The fans of the machine turn on, blowing their cacophony into the silent room. After twenty seconds — this is outdated technology, after all — you are presented with a login screen. You withdraw a notebook from your pocket and enter the details on the first page. The login is successful.

The next page of the notebook is a list of instructions written weeks ago. Combinations of buttons to press, commands to enter. You open two different terminals, enter a series of commands, watch lines of text you don’t understand flicker past your eyes. Eventually, when prompted by your instructions, you take a USB drive from your pocket and gently push it into the slot in the machine.

The screen goes black as the computer thinks about what it needs to do. A long, tense moment passes.

The file for SCP-3984 lights up the room as the page loads, dark red header contrasting against the bright white background, burning your eyes that have grown used to the darkness. You wince, and blink, and wait for your eyes to adjust.

You breathe a sigh of relief, relief that the instructions you were given worked, but it’s a feeling that you cut short. You’re here to solve a mystery that you’ve lived with your entire life, a mystery that no-one else seems to want to solve or even acknowledge, a mystery that’s been around for twenty-four years. And you hope — you have to hope — that this file will hold at least some answers. It’s the only place left to look.

The file begins with a note from one of the researchers. Reading from the top seems like a good way to start.

You don’t need to rush. You have all the time in the world.

Notice to all personnel

ΩK is a thing. It’s happened. We all have to live with it now.

Despite speculation — no matter how prevalent said speculation is — we do not know for sure whether or not we caused ΩK, whether any of our SCPs caused it, or whether any of them can fix it. We do not know whether it is related to the Foundation at all.

What we do know is that it now defines our lives.

The SCP Foundation does not destroy anomalies, it contains them. That is our purpose. ΩK is an anomaly and we will contain it. We will not end it, we will not "put things back" as certain individuals are asking. That is not our purpose, this is not our battle. However, we will contain it, or at least try to.

So if any of you are expecting my research team to come up with some magical solution to end ΩK, stop expecting that. We will treat the symptoms, but not cure the disease.

ΩK is here and it’s not going away, so grow up and move on. You are professionals — act like it. It’s not like this is going to kill you.

— Dr. Emily Young

Dr. Emily Young. A name you know very well, a name you've been trying to avoid for the past twenty years, a name that you completely expected to see.

And here, it's a name who's telling her researchers not to look into the origin of the crisis. Instead, she wants to focus on the symptoms?

You met Young last year, and suffice it to say that she is of very little use for research purposes. You'll get no benefit from talking to her. This document really is the last place you can look.

SCP-3984

End of Death Hub » SCP-3984

Item #: SCP-3984

Object Class: Keter

Special Containment Procedures: Containment of SCP-3984 revolves around inducing death in affected animals. As this is not currently possible, SCP-3984 can be considered uncontained. Research efforts must be directed into the development of alternative methods of inducing death.

Research into reversing the effects of ΩK, or its origin, is prohibited.

Prohibited? That doesn’t make sense. Why would the Foundation want to actively restrict research?

It must have been Young who enforced this rule. But why?

Description: SCP-3984 refers to a phenomenon in which any living organisms in the kingdom Animalia under Cavalier-Smith taxonomy1, including humans, are unable to die.

Currently, all known lifeforms in the kingdom Animalia are under the effects of SCP-3984. This satisfies the criterion for an ΩK "End of Death" scenario.

The source or origin of the prevalence of SCP-3984 as such is referred to as "ΩK". The exact nature of ΩK is currently under debate. This document pertains only to SCP-3984 and its effects, not its origin.

ΩK occurred on 2020-09-12 at approximately 14:02 GMT, a time which has been derived from the last globally recorded human death. Since that time, SCP-3984 has been present in every living creature thus tested. As a result, mortality rates have dropped to zero.

SCP-3984 appears to only extend to the ability to die. SCP-3984 does not grant a healing effect, does not prevent aging, does not prevent conception or pregnancy, and does not prevent subjects from sustaining injury.

In the long term, SCP-3984 presents a major threat to societal structure as the population is expected to expand exponentially. Current models estimate that overpopulation would begin to lead to excessive scarcity to the point of widespread starvation in the early 2040s. Additionally, while population growth is a considerable concern for humans in the long term, a much larger short-term concern is presented by animals with r-selected evolutionary strategies2.

Worldwide efforts should be focused on generating sufficient resources for the planet to be able to cope with the increased population. Talks with governments around the world to determine strategies for managing population growth, for both humans and animals, is underway. Foundation efforts should be focused on the development of alternative and/or artificial solutions to replace death.

The extent to which SCP-3984 constitutes 'conventional' immortality3 is the subject of ongoing research, which is led by Dr. Young as per request. Experimental logs and a theory on the mechanism of SCP-3984 is presented below.

Experiment Log 01

Date: 2020-09-14
Experimenter: Dr. Emily Young
Subject: D-1190

Procedure: D-1190 was asphyxiated by manual strangulation from D-9981.

Results: D-1190 struggled initially but stopped resisting after several minutes of strangulation. D-9981 was told to maintain grip for a further ten minutes. D-1190 recovered shortly afterwards with no lasting damage.

Experiment Log 02

Date: 2020-09-14
Experimenter: Dr. Emily Young
Subject: D-6812

Procedure: D-6812 was asphyxiated by D-9981 tying a belt around his neck.

Results: D-6812 initially resisted asphyxiation despite instructions otherwise, but stopped after several minutes of strangulation. D-9981 was told to keep the belt in position for a further ten minutes. D-6812 recovered with mild but permanent damage to several muscular ligaments in his neck.

D-6812 was admitted to the Site-06 medical ward but did not make any further recovery.

Experiment Log 03

Date: 2020-09-15
Experimenter: Dr. Emily Young
Subject: D-1190

Procedure: D-1190 was placed in a vacuum-sealed chamber from which the air was ventilated.

Results: D-1190 began to asphyxiate several minutes into the test, visibly struggling for air, and collapsed against the wall of the chamber after less than a minute, remaining conscious. Subject was left overnight, after which air was released back into the chamber. D-1190 was admitted to the Site-06 medical ward with acute cerebral hypoxia and burst blood vessels in the eyes. Subject physically recovered within three days but remained in a vegetative state for several weeks. Upon awakening, D-1190 displayed symptoms of permanently-impaired motor and speech skills as well as widespread paralysis.

2020-11-02: One month after waking up, D-1190 has not shown any signs of further recovery. It appears that the anomalous nature of the healing effect extends only to fatal injuries or ailments. D-1190 remains effectively useless as D-Class. Under usual circumstances, I’d recommend termination. - Dr. Emily Young

Experiment Log 04

Date: 2020-09-17
Experimenter: Dr. Emily Young
Subject: D-8833

Procedure: D-8833 had cuts made on her wrists and ankles and over the course of 6 hours was drained of an estimated 80% of her blood. Removed blood was retained and re-introduced to the body the following day via intravenous drip.

Results: In much the same manner as the previous experiment, D-8833 was successfully 'resurrected' but has suffered injuries consistent with prolonged loss of oxygen to the brain. In this instance, symptoms included loss of sensation in the left half of the body and loss of understanding of any subject more complex than naming animals. Note that D-8833 remained conscious despite not having a significant volume of blood.

The logs continue in much the same fashion, with some unfortunate D-Class being exposed to something that would normally kill them. Poison, starvation, explosion, whatever. You scroll down, looking for one in particular. The old scrollwheel clicks loudly, twenty times with each movement of your finger, a series of loud clicks that echo through the silence of the library. You stop at Experiment 10.

Experiment Log 10

Date: 2020-10-11
Experimenter: Dr. Emily Young
Subject: D-11424

Procedure: D-11424 was decapitated with a steel-bladed guillotine.

Results: Head was cleanly removed. D-11424 remained conscious during and after the operation. Efforts were made to breathe, which failed, and D-11424 began to show signs of suffocation and significant blood loss. Although D-11424 was admitted to the Site-06 medical ward, the injury was deemed "irreparable". Both head and body were placed into cold storage.

You smile, lifting your hand to touch the raised scar that forms a ring around your neck and the tiny bumps from age-old stitches. Irreparable.

You keep scrolling.

Experiment Log 20

Date: 2025-11-05
Experimenter: Dr. Emily Young
Subject: D-10273

Procedure: One round from a standard-issue security handgun was fired into the forehead of D-10273 by Dr. Young.

Results: Subject sustained major head injury was admitted to Site-06 medical ward with severe brain damage and blood loss.

2025-12-28: After almost two months under medical care, D-10273 has made a full recovery, albeit with major memory loss of both recent and earlier history. Subject remembers basic skills such as how to eat and speak but does not recall any personal details.

Experiment Log 21

Date: 2025-12-31
Experimenter: Dr. Emily Young (stand-in: Dr. Joyce Michaels)
Subject: Dr. Emily Young

Procedure: Dr. Young self-administered a single bullet to the head from a security handgun in much the same manner as the previous test.

Results: Subject sustained major head injury and was admitted to Site-06 medical ward. Bullet had pierced the temporal lobe, frontal lobe and brainstem, the latter of which appears to have disconnected Dr. Young's brain from her body. She is unable to communicate or perform any motor functions.

Note: As Dr. Young is incapable of performing further research, she has been removed from the SCP-3984 research team. She will undergo a psychological review pending on her recovery. In the meantime, I will be assuming control of research. - Dr. Joyce Michaels

Note: Dr. Young has neglected to maintain a log of specific research intentions for each experiment. Despite this, we have been able to narrow down the source of the immortality to the brain. Subsequent experiments should focus on this — we can consider the rest of the body to be mortal. - Dr. Michaels

Michaels isn't wrong. You’ve seen someone in a car crash, their body mangled beyond recognition, limbs in places they shouldn’t be and blood everywhere that they should, but that should-be corpse still found the energy to call for help, to scream in pain. You don’t imagine they ever stopped.

You remember meeting Young last year. She hasn't changed much since this experiment. You couldn't tell whether or not she was happy to see you.

Experiment Log 22

Date: 2026-02-02
Experimenter: Dr. Joyce Michaels
Subject: D-373A, a male Macaca mulatta or Rhesus macaque

Purpose: To confirm or deny the above assumption.

Procedure: D-373A was given a standard lethal injection dose4.

Results: Primary injection was unable to cause D-373A to become unconscious; however its vocalisations became slower and panic-like symptoms were noted. Secondary injection saw widespread muscular relaxation and induced breathing difficulty. Tertiary injection quickly induced cardiac arrest, through which D-373A remained conscious and visibly panicked throughout despite severe muscular relaxation.

After 12 hours, when the administered drugs were declared to be no longer actively causing symptoms in the subject, D-373A was admitted to the Site-06 medical ward with acute cerebral hypoxia from the lack of blood flow. Note that D-373A remained conscious throughout the experiment.

2026-02-25: With medical attention from Site-06, D-373A has made a full recovery with no permanent side effects.

Note: It is interesting to observe that sedation was unable to induce unconsciousness in the subject. It might be not that the brain is immortal, but that it is impossible to cause one to become unconscious. - Dr. Joyce Michaels

Experiment Log 23

Date: 2026-02-07
Experimenter: Dr. Joyce Michaels
Subject: D-374A, a female Macaca mulatta or Rhesus macaque

Purpose: To confirm or deny the above assumption: that it is not possible to cause the brain to become unconscious.

Procedure: Over the course of 5 days, D-374A was injected with:

  • A mild sedative
  • A strong sedative
  • A mild local anaesthetic
  • A mild general anaesthetic
  • Class C amnestics

Results: D-374A responded positively to the mild sedative (dosage was insufficient to cause sleep), local and general anaesthetic and amnestics. D-374A had no response to the strong sedative — in fact no effect of the sedative was observed, despite the weak sedative showing a positive drowsiness response.

Note: Sedation, at least to the point of unconsciousness, is not an option for future experiments. This supports the above assumption. - Dr. Joyce Michaels

Experiment Log 24

Date: 2026-02-19
Experimenter: Dr. Joyce Michaels
Subject: D-390A, a female Macaca mulatta or Rhesus macaque

Purpose: To establish if the effects of SCP-3984 hold even when the brain no longer conventionally exists.

Procedure: After being restrained, the skull of D-390A was surgically opened from the top down to the neck. Connection to the spinal column was severed and the brain was removed. As damage to neurons and other brain cells are not at risk, the brain was separated into individual cells through a combination of chemical disaggregation and mechanical trituration (with a blender). Individual brain cells were then suspended in a saline solution.

The resulting mixture, referred to as Solution-3984-24, was placed through a series of tests to determine its electrical activity.

Results: Electrical signals persisted throughout the brain cells suspended in solution as would be expected for a healthy human brain, leading to the conclusion that D-390A affects the individual cells of the brain itself. Despite this, it was not possible to determine whether or not D-390A remained "conscious", as an MRI scan was inconclusive on account of the not-brain-shaped nature of the solution and randomisation of cell locations. Samples of Solution-3984-24 are available upon request.

You've seen enough test logs. None of them contain the information you're looking for. You know that at some point there'll be one where they reconnect D-11424's severed head, but beyond that, none of them interest you.

You scroll right down to the bottom of the page.

Summary of research: Through research orchestrated by Dr. Young and Dr. Michaels, overall, SCP-3984 can be characterised by an inability for the brain to become unconscious. The current theory proposes that SCP-3984 does not represent immortality as such, but rather an inability for the brain to lose function. The amount of function is not retained so long as the brain itself remains operable (see Experiment 03).
