Description: SCP-2377 is an audiovisual phenomenon localized 
within a single house, designated SCP-2377-1, in , .ltis not 
yet understood how SCP-2377 manifests but research into primary 
memetic, esoteric, and technological theories is ongoing. The 
phenomenon consists of the appearance of two individuals who are 
intangible to those within SCP-2377-1 but are fully tangible to one 
another. SCP-2377 scenarios occur at irregular intervals’ but all 
scenarios depict cases of homicide with specific shared attributes: 


The perpetrator of the homicide and the victim, designated 
SCP-2377-a and SCP-2377-b respectively, are the only 
individuals to appear within SCP-2377-1 at a given time. The 
appearance of one or both signifies the beginning of an 
SCP-2377 scenario.2 Clear homicidal intent in SCP-2377-a is 
always present, as assessed by Foundation personnel who 
have witnessed a scenario. Instances of SCP-2377-a and 
SCP-2377-b are unique to each scenario.3 

Since the beginning of SCP-2377's monitoring, 95 of the 178 
victims displayed in SCP-2377 scenarios have later been 
confirmed as deceased? within the same time window as their 
associated scenario; the remaining 83 victims have not as of 
yet been identified but are presumed deceased. In the cases 
of confirmed deceased SCP-2377-b instances, SCP-2377-a 
instances have been identified and suspected or arrested of 
the homicide. It is currently theorized that all SCP-2377 
scenarios are happening simultaneously within SCP-2377-1 
and at their origin locations. 

Depicted scenarios have thus far only been confirmed as 
occurring in similarly freestanding housing structures to that of 
SCP-2377-1; apartment buildings, condominiums, duplexes, 
and other multi-residential constructs do not seem to facilitate 
SCP-2377 scenarios. 

SCP-2377 scenarios which have been identified have all 
occurred within approximately 1,200 kilometers of 
SCP-2377-1. 

While SCP-2377 scenarios are visible to all within 
SCP-2377-1, looking into SCP-2377-1 from outside produces 
no result. To date, instances of SCP-2377 have not been 


successfully recorded by any format except human 
observation. 

* To date, SCP-2377-b has been killed in every recorded 
scenario with no deviation. In addition, only 6 scenarios have 
included SCP-2377-b succeeding in killing SCP-2377-a in 
their attempts at self-defense. 


Certain patterns seem apparent but not requisite of SCP-2377 
instances; at least 152 of the recorded instances have been 
classified as home invasion or domestic disturbance scenarios, and 
nearly 90% of perpetrators have been identified as male. SCP-2377 
scenarios where the origin location's floorplan differs significantly 
from that of SCP-2377-1 in size or style seem to account for the 
discrepancy. If either SCP-2377-a or SCP-2377-b would move to a 
room that SCP-2377-1 doesn't contain a direct analogue of, one or 
both will fade from visibility briefly before reappearing in the room of 
closest possible correspondence within SCP-2377-1. Audio is not 
interrupted during these periods although volume levels have been 
documented to experience shifts. 


Residential history of SCP-2377-1 shows no connections to any 
previously known GOI or POI in Foundation records. SCP-2377-1 
came to the attention of Foundation personnel after reports were 
picked up in a monitored regional IRC chatroom frequented by 
nursing industry professionals. These reports described a transient 
individual who had been illegally residing within SCP-2377-1 making 
asceneat ' Memorial Hospital regarding three homicides he 
had claimed to witness. The transient individual was not remanded 
on scene by local authorities and has not yet been recovered; he 
has since been classified POI-2377-01. Procurement of SCP-2377-1 
was completed on 10/14/199 via Shinjuku Complex Properties, a 
Foundation front company. It is unknown when SCP-2377 first 
manifested or the number of instances that may have occurred 
before official documentation began but public record shows that 
SCP-2377-1 had been officially vacant for approximately three years 
before acquisition by the Foundation.® 


Due to an inability to independently verify the events that occur 
during each SCP-2377 scenario, the Foundation has chosen not to 
disclose information regarding SCP-2377-a instances to local 


authorities in cases where an SCP-2377-b instance's identity has 
been confirmed. 


Addendum 06/21/200 : Comparative analysis of multiple witnesses’ 
physical descriptions of SCP-2377-a instances has lead to the 
designation of POI-2377-02, an individual determined to be 
responsible for the homicide event in at least SCP-2377 scenarios; 
the SCP-2377-a instances in these scenarios have uniformly not 
been identified. 


Incident Report 2377-01: 
+ Level 3 Security Clearance Required 


On the evening of 08/05/200 , four civilians attempted a 
breach of Containment Site 2377. While not sufficiently 
trained or armed to pose a significant threat to the lives 
of the MTF B-19 members dispatched to neutralize the 
situation, the civilians were markedly aggressive and 
organized in their operation. Suppression was 
successful; three of the four civilians, however, were able 
to commit suicide by means of firearm before being 
neutralized. The surviving intruder, identified as a W 

M and hereafter classified as POI-2377-03, was 
detained and sedated before being moved off-site. 
Interrogation was conducted at Area on 08/06/200 by 
Researcher . Falconer. 


<Begin Log, [08/06/200 17:35:06]> 


Researcher Falconer: State your name for 
the record. 


POI-2377-03: Fuck you. 


Researcher Falconer: You had your wallet on 
you when you attempted to break into our 
facility. You're W M , correct? 


POI-2377-03: (inaudible) 


Researcher Falconer: Come again? 


POI-2377-03: | said we weren't trying to break 
into your stupid fucking building. 


Researcher Falconer: Ah, fair point. You 
wanted the house. 


POI-2377-03: Close enough. 


Researcher Falconer: If it wasn't the house, 
then what Mr. M ? 


POI-2377-03: (laughs) You wouldn't 
understand. And don't call me that. 


Researcher Falconer: What wouldn't we 
understand? What do you think you know 
about what happens in that house? 


POI-2377-03: (increasingly agitated) What do 
you know, asshole? You think what happens in 
there is some shadowplay, that we're here to 
get spooked or get our rocks off? Does it 
matter to you, what you see happen in there? 


Researcher Falconer: Of course it matters to 
us. Why do you think we watch - 


POI-2377-03: Bullshit. You watch because you 
don't have the slightest goddamned clue why 
you can see them. See him. 


Researcher Falconer: The man that keeps 
showing up? You know who he is? 


POI-2377-03: Not yet, but we will. We'll find 
him. He understands. He belongs with us. Not 
out there by himself, like the rest of you. 


Researcher Falconer: He understands what? 
Who do you mean by “we”? 


POI-2377-03: Alone is alone. 


Money Entered: 1,993 yen 

SCP-261 Powered or Unpowered: Unpowered 

Item Description: "Mighty Morphin Power Ranchers; Megazord 
Size!" - a 48 oz bag of the previously produced hard candy (see 
above). The phrase "One Dinozord in every pack! Collect them all 
and form the legendary Megazord!" is printed directly below the 
label. Contents were as expected, and included a small plastic 
replica of the "Sabertooth Dinozord". All contents were determined 
to be non-anomalous. 

Researcher's Note: "Didn't entering '1999' yen produce a similarly 
date-specific item? What is it with this machine and the 90's?" -Dr. 
/ 


Money Entered: 500 Yen 

SCP-261 Powered or Unpowered: Powered 

Item Description: Sassparilla - A bottle of root beer. Its label is 
typical of modern reproductions of root beer-type soft drinks. No 
unusual taste reported. Upon consumption, subject became irritable 
and cocky, making snide remarks to researchers with little 
provocation. Subject terminated following an especially rude remark 
regarding Dr. _'s mother. Afterwards, researchers became 
confused when asked the reason for their aggression towards the 
late subject. Object classified as a cognitohazard. Further tests 
pending. 

"Son ofab had it coming. " -Dr. 


Dr. Allok engaged in testing to determine if allowing SCP-261 time to 
“cool down” would help keep more dangerous or unpleasant 
foodstuffs from appearing. Testing followed a fifteen minute cycle, 
each test utilizing 500 yen. This cycle was repeated until anomalous 
items were produced, then testing was suspended for two hours 
before resuming. During testing suspension, SCP-261 remained 
unused by any other parties. 


Dr. Allok's notes: It seems to overheat, let's be honest. Push it 
hard and long enough, and it's going to drop something dangerous. 
Plus, dumping too much money in it seems to confuse it, for lack of 
a better term. So we take it slow and steady. 


Researcher Falconer: What? 
POI-2377-03: Fuck it. I'm done here. 


Researcher Falconer: Why did your 
compatriots kill themselves? 


(POI-2377-03 refuses to answer any more 
questions from this point forward.) 


<End Log, [08/06/200 17:39:38]> 


Closing Statement: Following this interview, 
POI-2377-03 has been designated for 
permanent detainment at Area. Continued 
attempts at questioning him have so far proven 
useless. After a failed suicide attempt, 
containment procedures for POI-2377-03 are 
being reevaluated. 


Following Incident 2377-01, on-site personnel 
requirements have been adjusted to account for potential 
future attempts at containment breach by groups of 
equitable or slightly increased power. Designation for a 
currently unidentified GOI is pending review. 


Scenario Report 2377- 
+ Level 4 Security Clearance Required 


Routine surveillance of SCP-2377-1 on 11/28/200 was 
in progress when an SCP-2377 scenario began. The 
SCP-2377-a instance was quickly identified as 
POI-2377-02 by multiple personnel who had witnessed 
previous scenarios. The scenario lasted sixteen hours, 
constituting the longest such occurrence involving 
POI-2377-02. Shortly before the SCP-2377-b instance's 
expiration, POI-2377-02 wrote the following message 
across SCP-2377-b's back with a black marker: 


ALONE IS A LOAN. 


Following the end of this scenario, a more intensive 
investigation into the backgrounds of all former residents, 
instances of SCP-2377-a and SCP-2377-b, the civilians 
who attempted to breach containment, and all familial 
and social connections for each of these has begun. 
Classification of a new Group Of Interest, hereafter 
GOI-19177, has been approved. All POI-2377 subjects 
have been designated as Presumed Involved; 
SCP-2377-a subjects excluding POI-2377-02 are to be 
designated Potential Candidates. Priority Level for 
GOI-19177 is classified Low at the time of this writing. 


Footnotes 

1. Recorded intervals have ranged between nine hours and fourteen 
days. 

2. The durations of SCP-2377 scenarios have ranged between three 
minutes and six days. 

3. See Addendum 06/21/200 . 

4. Cause of death as determined by local authorities has in almost 
every case been considered unnatural. While a majority have also 
been labeled as homicides, infrequent determinations of accident or 
suicide do occur. 

5. If initial manifestation is hypothesized to be the cause for the 
extended vacancy and SCP-2377 instances have not increased or 
decreased significantly in frequency over time, it is estimated that 
approximately 32 instances occurred before the Foundation took 
control of SCP-2377-1. This number currently cannot be 
substantiated but has been approved as a baseline variable for 
supplemental demographic computations by Foundation research 
personnel. 

6. Foundation resources have not been allocated to confirm or 
elaborate on the forensic analysis of crime scenes performed by 
those within the local jurisdiction of confirmed cases.

SCP-2378: Tissue Dome 


Item #: SCP-2378 
Object Class: Euclid 


Special Containment Procedures: SCP-2378 is to be contained in 
an outdoor enclosure with a 5 km radius between the structure and 
the edge of the containment enclosure. The enclosure area is to be 
designated a no-fly zone. Containment barriers should be 
constructed of durable metal coated in Teflon polymer. CCTV 
monitoring cameras are to be implanted in concealed locations 
along the fenceline at intervals of 50 meters. Civilians attempting or 
successfully entering the containment enclosure are to be 
apprehended and administered class A amnestics as required. 
Satellite imagery should be modified such that SCP-2378 resembles 
weathered rock layers. 


Exploration and Research teams entering SCP-2378 must have at 
least BSL-2 safety training. Individuals entering A regions are not to 
have consumed more than 36 mg of glucose for at least 3 hours. 
Physical contact with SCP-2378-1 instances should be avoided, 
especially if entering SCP-2378-B or C regions. Exploration of B or 
C regions require BSL-3 and 4 safety protocols, respectively, and 
use of appropriate liquid immersion equipment. Physical interaction 
with SCP-2378-4 should be avoided by personnel at all costs. 


Entry into SCP-2378-D is restricted to aerial corrosion-proof drones. 


Irritation of the interior elements of SCP-2378 should be avoided. In 
the event of a Class 1 event, research and exploration crews within 
A regions are instructed to secure themselves to tunnel or cavern 
walls via provided equipment. Personnel in B or C regions are 
instructed to evacuate to A regions immediately. If SCP-2378 enters 
a Class 2 event, all personnel are to be evacuated and the 
surrounding area placed under lock down. 


At the end of every designated 8 month period, personnel are to be 
barred from entering SCP-2378 until the transition point has 
elapsed. Genomic analysis is to take place following this transition, 
at which time the new link is to be identified and tracked for 
observation. 


Use of SCP-3536-1 instances have been approved for testing within 
SCP-2378 on a case by case basis. 


Description: SCP-2378 is a large domed structure located 15 km 
from Site-234 in , Alabama. SCP-2378 is circular at its base, 
with a diameter of 3 km and a maximum height of 200 meters. The 
structure's exterior is grey in pigmentation and composed of large 
interlocking amorphous structures morphologically similar to human 
epidermis tissue, which resemble weathered limestone from a 
distance. Between these structures are holes, 5-10 cm in diameter, 
from which .5 meter long keratin fibers, ranging from dark blue to 
black in pigment, protrude. All attempts to drill or cut portions of the 
exterior have failed, usually inducing small seismic events. All 
components of SCP-2378 defy normal biophysical evolution to some 
degree, notably, the gravity defying flow of nutrient processing in the 
upwards direction and violation of biological principles derived from 
the Square Cube Law. 


All interior and exterior structural components of SCP-2378 are 
composed of cells, tissues, and organs similar to those of human 
origin at approximately 10,000 times their normal size. These 
components correspond, genetically, to a single real world 
individual, and often display physiological signs congruent with the 
current health of said individual. Linked individuals appear to be 
spatially connected to SCP-2378 in some unknown manner, 
however; individuals remain unaware of said spatial connection 
throughout its duration.
