SCP Involved (Y/N): Y 


* Designation: SCP-2401-Alpha 
¢ Containment Breached (Y/N): Y 


Details: SCP-2401-Alpha, prior to incident, 
exhibited agitated behaviors for a period of ten 
days. SCP-2401-Alpha had difficulty 
expressing the source of its agitation, often 
deploying cryptic statements and referring to 
itself in the first person plural by its actual 
name prior to symbiosis. Dr. Kenneth Lamb, 
the acting supervisor of SCP-2401, postulated 
that SCP-2401-Alpha was delirious. 


72 hours prior to incident, SCP-2401-Alpha 
suffered from an apparent seizure and 
collapsed onto the floor. Time was noted and 


logged. The body was kept under watch as 
standard in the operating procedures for 
human subject quarantine. After 48 hours, the 
site director extended quarantine to Cell-22 for 
another 24 hours. No activity was observed 
from the host or the colony. The cell floor was 
littered with dead instances of SCP-2401 at 
this time. 


Personnel and security entered Cell-22 after 
the quarantine period expired in order to 
retrieve the body for examination and autopsy. 
While decontaminating and preparing the body 
for transfer, SCP-2401-Alpha suddenly 
awakened and physically attacked security. 
Both guards suffered concussions from the 
altercation. 


Dr. Lamb was then tackled to the floor outside 
of containment and stripped of his clothes by 
SCP-2401-Alpha. On video, Dr. Lamb was 
held down on his back with SCP-2401-Alpha 
atop of him for a period of 90 seconds. From 
the video's limited vantage point, it was difficult 
to ascertain what was happening to Dr. Lamb 
as he showed limited signs of struggle. 


Afterwards the majority of security forces 
subdued SCP-2401-Alpha with electroshock 
weaponry to force it off of Dr. Lamb and back 
into containment. Dr. Lamb suffered only a 
dislocated shoulder and minor abrasions. 
SCP-2401-Alpha has since replenished the 
SCP-2401 colony to a fully restored population 
and has been observed to be more docile as 
compared to before the incident. 


Addendum-2401-001: Due to SCP-2401-Alpha's recent 
containment breach, staff and security teams are prohibited from 
entering Cell-22 or conversing with SCP-2401-Alpha without direct 
authorization from the Site Director. Further research into SCP-2401 


or SCP-2401-Alpha has been put on hold indefinitely.

Agent Foster: Alright. Recorder is on. How 
are you holding up? 


Dr. Lamb: I'm... still in shock over the whole 
thing | guess. 


Agent Foster: Well let me just ask, why do 
you think you were chosen? 


Dr. Lamb: | don't know. 


Agent Foster: Well, you were assigned to her 


Dr. Lamb: It. 


Agent Foster: Right, /t, for three months. You 
interviewed with it every other day it looks like. 


Dr. Lamb: | monitor other humanoids in that 
wing too. 


Agent Foster: So back to my original 
question. 


Dr. Lamb: P-perhaps... maybe the human 
inside her— | mean it made a connection? 


Either way, it— (sigh) it got what it wanted 
from me. Oh God. 


Agent Foster: You feel like you can continue? 


Dr. Lamb: | suppose. Sorry, I'm still just... 
rattled over the whole thing. 


Agent Foster: Well medically you checked out 
fine. Just bumps and scratches. So there's 
that. 


Dr. Lamb: ... 


Agent Foster: Look, | don't want to push you 
after something traumatic like that. Anything 
you want to say on the record? 


Dr. Lamb: | want the injection. Give me the 
injection and give me a transfer. P-please. 


Agent Foster: (scribbling) | gotcha. I'll see 
what | can do.

SCP-2401-Alpha: Mary. 
Agent Foster: E-excuse me? 


SCP-2401-Alpha: We liked to be called Mary. 
(buzzing) 


Agent Foster: Fine. Mary. What was your 
relationship to Doctor Lamb? 


SCP-2401-Alpha: Relationship? Is that what 
he called it? Him and us? (/ight buzzing) 


Agent Foster: Nevermind. Can you explain 
then what you did to him the last time you two 
were together back in February? 


SCP-2401-Alpha: We remember him being 
quiet and rather content about it. 


Agent Foster: Well. He was adamant about 
not wanting to see you ever again. 


SCP-2401-Alpha: (buzzing stops) Hmmm, we 
don't believe you. We are happy with the 
outcome still. 


(SCP-2401-Alpha slowly rubs her hands over 
her swollen abdomen.) 


Agent Foster: This... part of the cycle? 


SCP-2401-Alpha: (buzzing resumes) |t is and 


it is not. We need sterner hosts. The females 
are fragile yet willful. Strong queens for strong 
colonies. 


Agent Foster: ... 


SCP-2401-Alpha: Our sweet Kenny. Tell him 
for us that his progeny grows stronger with 
each passing day. Tell him we all await his 
return.

SCP-2402: That Takes Me Back 


Item #: SCP-2402 
Object Class: Euclid 


Special Containment Procedures: SCP-2402-1 through 3 2 are to 
be kept in a locked standard storage drawer at Site-17. All requests 
for testing or other purposes must be logged, with digital copies of 
the date, time, person requesting access, and reason for requisition 
kept at three separate facilities. Logs must be cross-referenced at 
least once monthly for discrepancies. 


All testing with SCP-2402 instances must take place in soundproof 
testing chambers constructed no later than 1996. If soundproofing 
foam is found to be worn or decaying, testing may be allowed to 
continue with specific permission and increased protection from the 
principal researcher or site director. Care must be taken to use 
speakers with enough age to survive testing. 


Description: SCP-2402 is a chord progression in the normal range 
of hearing for humans. The specific frequencies for each note 
involved and the length of each note in succession are listed in 
Document 2402-KS [REQUIRES 4/2402 CLEARANCE]. 


The chord progression causes an anomalous harmonic vibration 
within subatomic particles, causing a reversion of particles to a prior 
oscillation with lower entropy. Rapid shifting of subatomic 
oscillations to previously exhibited states effect a temporal reversal 
in the exposed materials. In organic materials this reduction in 
entropy is generally observed to consist of the recomposition of cells 
and tissues. For example, a rotting fruit will return to an edible state. 
Living plants and animals will appear to become younger, with no 
corresponding temporal shift in the environment outside the listening 
area. 


The rate and intensity of temporal reversal is dependent on the 


strength of exposure. Sound pressure levels of at least 40 dB are 
necessary for the anomalous nature of the progression to become 
clear. The anti-entropic effects of the progression cease for any item 
moved to a range where the amplitude of SCP-2402 is less than 
40aB, but accumulated temporal reversions remain in place 
afterwards. Test subjects and test materials have been observed to 
become younger at a rate of 6 months per minute of exposure at 

70 cB. 


Analysis of brain scans and interviews of subjects after testing have 
demonstrated that the mind also reverts to an earlier time, removing 
all memories accumulated over the "rewound" period. Researchers 
are advised that extreme fear and confusion are common reactions 
to test subjects immediately after testing, as they will not remember 
why they were in the testing chamber, remembering only events up 
to their new, previous chronological age. Should subjects revert 
back to earlier than the adult state, the subject will decrease in 
mass, with the balance expelled as undifferentiated viable tissue. 


Test materials also experience entropy removal, resulting in 
reduction of wear and fractures. Recent construction of buildings 
can potentially result in disassembly of exposed rooms upon 
reversion to the date of construction, via the refilling of nail holes in 
wood, reversal of welds, and re-separation of concrete binding 
materials. Ensure that testing chambers are never exposed to a 
cumulative level of regression past their date of construction. 
Because of this property, older facilities in need of repair can be 
used as testing chambers, as long as the principal researcher has 
determined limited propagation of acoustic properties beyond the 
confines of the chamber. 


SCP-2402-1, -2, and -3 are the objects in containment which carry 
recorded forms of SCP-2402. SCP-2402-1 is a musical manuscript 
using Byzantine notation. SCP-2402-2 is the file pureyouth.mkv, 
kept on a single 64GB thumb drive. SCP-2402-3 is [DATA 
EXPUNGED] Testing with SCP-2402-1 is restricted until Foundation 
musicians who have memorized the score have aged sufficiently to 
remember the score upon conclusion of play. Please refer to 
Personnel Roster 2402-1-09X for a list of Level 2/2402 clearance 
musicians, and date of memorization of SCP-2402-1. During testing,

copies of SCP-2402-1 can be made available to musicians only if 
they are properly aged for a minimum of 7.5 years via SCP-119 
before play. Regular testing of SCP-2402's effects is to be 
performed with SCP-2402-2, which can be played to speakers 
physically separated from the computer hosting the file. 


Addendum: Recovery Log, SCP-2402-1: 


MTF Eta-11 ("Savage Beasts") was dispatched to the village of : 
Bulgaria, to investigate rumors of the locals offering "a song that 
restores youth and virginity" for a considerable price. A number of 
musicians in the village were identified as persons of interest and 
surveillance was established. MTF members posed as paying 
clients and were able to infiltrate operations, and asked to join the 
musicians in a nearby cave in the Balkan Mountains. Average age of 
the musicians was approximated as 45-50, although the youngest 
(POI-2402-4, approximately 25 years of age) informed Agent Zhao 
that he has played the song longer than anyone else, and soon he 
would not be able to play it anymore. Zhao effected payment for "3 
years of youth" and allowed to remain in the cave while the 
musicians played. The remaining members of MTF Eta-11 carried 
out a tactical assault [DATA EXPUNGED]. 


MTF confirmed the anomalous effects of the music through an 
examination of the regression of mole development on Zhao's skin 
and comparing them to medical records. SCP-2402-1 was 
recovered in the cave, along with 5 traditional Bulgarian instruments 
of recent make (gaida, kaval, tupan, 2 tamburas) and a recently 
made forgery of a Stradivarius violin. 


POI-2402-4 was the sole survivor of the encounter among the 
musicians, but was determined to no longer be a threat and left at 
the nearby monastery with a forged note claiming to be from his 
mother. 


Addendum: Recovery Log, SCP-2402-2 


The file pureyouth.mkv was located on a cloud server, having been 
uploaded by , a musician in New York City. It was 
sequestered and transferred to thumb drive and wiped from the 
internet, and Mr. was brought in for questioning. Upon 


interrogation, he revealed that he had no recollection regarding 
writing the music, and appeared to be suffering from retrograde 
amnesia, believing that the current date was six months earlier. 
Subject was given a Class B amnestic and released. 


| think what's going on is that you've got musicians who 
come up with this chord from time to time, but then while 
they're tinkering with it, they play it, they back up, and 
they can't remember ever having played it before. In 
many ways, it's self-containing, but now in the world of 
digital music, where something can be written out ina 
playable form without ever listening to it, first, there are 
more and more ways for files like this to end up in the 
public.
