<The SCPS-lago’s pressure chamber floods 
with water. Gamma-6 is submerged. The 
diving chamber opens approximately 40m 
above SCP-3391. Gamma-6 swims toward the 
outside of SCP-3391, a short distance from the 
fissure. Several instances of SCP-3391-1 are 
present in the water.> 


Delta: Jesus. Never got to see the thing up 
close before. 


Alpha: Command, we’re approaching 
SCP-3391-2. How do you copy? 


Command: We're reading you, loud and clear. 
No electromagnetic disturbances. 


locked 38 L (10 gal) Type-G containment unit with connected 
oxygen supply. Specimen is to be fed through Feeding Tube 16a 
with Approved Nutritive Substance X-F. Handling is available to 
Level 2 personnel and higher. 


Description: SCP-489 is an insect of unknown origin, somewhat 
resembling a greyish, semitranslucent Forficula auricularia (common 
earwig), approximately 2.5 cm in length. Originally located/obtained 
in mainland China in the province. No other specimen has 
been found, as of yet. 


SCP-439 is relatively harmless when encountered on safe terms, 
aside from the ability to deliver a firm, painful pinch with its 
abdominal forceps. The true hazard this creature poses lies in its 
habitat construction and reproduction, which is initiated when the 
specimen enters the mouth of a sleeping human. This will on/y occur 
with humans; other lifeforms have been presented to SCP-439 and 
have been uniformly rejected. Upon location of a suitable host, the 
specimen will hide itself in the immediate vicinity and wait until the 
victim has fallen asleep. How it is able to determine the state of 
sleep is unknown, but it has shown to be accurate in [DATA 
EXPUNGED] times out of [DATA EXPUNGED]. Upon entering the 
mouth of the new host, SCP-439 will travel down the trachea and 
take up residence in one of the victim's lungs. 


In approximately 4-8 hours, after awakening, the host will complain 
of chest pains and shortness of breath, followed shortly by 
abdominal cramping. The tightness in the chest will increase as well 
as a fever until the host is incapacitated. It is around this time that 
the onset of Fibrodysplasia Ossificans Progressiva (FOP) occurs, a 
disorder that is normally genetic in nature that promotes growth of 
bone into muscle tissue. Since the production of new bone growth is 
so rapid, the procedure is also quite painful for the subject, with new 
bone spurs occasionally protruding through the flesh. While this is 
happening, the host will become compelled to seek shelter ina 
darkened, enclosed space, such as inside household cabinetry, 
closets, or heating ductwork. 


Within the first three days without treatment, the host will become 
completely withdrawn and immobile due to the extreme pain of new 
bone growth coupled with difficulty breathing. At this point, the 


Epsilon: Hey, do we know what those yellow 
streaks above us are? We shouldn't be 
worried about those, right? 


Delta: As far as we can tell, it’s just jumbled 
organic lipids and proteins. It should be inert, 
but keep an eye on it anyways. Alpha, how are 
the readings? 


Alpha: Same as the probes they sent down 
here. Kant Counter is reading a steady 92. 
Pressure’s at 47 bar. Nothing unusual. 


<MTF Gamma-é6 reaches the opening in 
SCP-3391, known as “the fissure” by the team, 
and identified as such for the rest of this 
document. SCP-3391-1 instances are 
observed to approach, but never interact with 
personnel. Extraneous dialogue removed for 
brevity. Upon arrival at the fissure, visibility 
noticeably degrades, due to the presence of 
the organic yellow substance in the water.> 


Delta: Command, we’re at the fissure. 


Beta: Looks to be about twenty metres wide 
and a couple hundred long. | can’t see the 
bottom, there’s too much of that protein crap. 
You sure the yellow stuffs harmless? 


Command: You should be fine in your suits. 
It’s not caustic or reactive. 


Epsilon: Alright. Sonar maps measure this 
thing to be around two hundred metres deep. 
Delta, you’re the one with the most experience 
with this kind of stuff. How do you want to 
handle this? 


Delta: Prep your gear and keep a close watch 
on your periphery. There’s no telling what 


could be in that fog. Beta, fix the harnesses at 
the mouth of the fissure. We’re going in. 
Command, keep an eye on the lago and the 
extraction zone. 


Beta: Roger that. 
Command: Roger. 


<Beta sets up stakes at buried within 
SCP-3391-2, which was considered firm 
enough to provide adequate leverage. MTF 
Gamma-6 attaches their harnesses to the 
stakes.> 


Alpha: We're entering the fissure now. 


Command: Copy that, team. Try to avoid 
confrontation if at all possible. 


Delta: Got it. We're diving. 


<The team enters the fissure, drifting through 
the water. The walls of the structure are not 
visible. After two minutes, they land at the 
bottom of the fissure.> 


Alpha: Okay. We’ve landed. Collecting a 
water sample. Ugh, the ground’s all sticky. 
Looks like... fresh meat. It’s red and healthy, 
not like the brown stuff on the surface. 


Delta: It feels like the fissure's shaking. 
Command are you reading seismic 
disturbances on your end? SCP-3391 seems 
to be... thumping, at around 50 bpm. 


Command: No readings up here. It’s localized 
to the inside of the anomaly. 


Alpha: Alright then. Let’s find a wall, see if we 
can't find something interesting. 


<MTF Gamma-6 walks to the northeast for 
approximately four minutes. They come across 
a sheer cliff that extends into the yellow fog 
above. At this point, they are well outside of 
the surface-boundaries of the fissure. There is 
a large vertical slit in the wall, with several 
lengthy folds of striated tissue surrounding it. It 
appears to be pulsing rhythmically. During this 
time, radio contact is lost with the team due to 
their distance from Command. All further 
dialogue and footage is recovered post- 
mission from the squad’s personal recording 
devices.> 


Alpha: Command's out. We’re on our own 
from here. 


Beta: Are we going to talk about, you know, 
the big vag on the wall? 


Epsilon: It’s a portal, or a door. I’ve seen this 
kind of organic engineering in Hungary. Looks 
like we’re dealing with something manmade. 


Alpha: Is there a chance we might meet 
resistance in there? 


Epsilon: We're equipped to deal with the -1s 
but there's no telling what we'll find behind this 
door. Just keep your gun close to you. 


Delta: Hang on. I’m interacting with the 
anomaly. Have my tether ready. 


<Delta touches the edge of the growth. After 
several seconds of this motion, he reaches 
into the centre of the slit. As he does so he is 
forcefully pulled into the opening. His bodycam 
records approximately fifteen seconds of rapid 
motion through a thin passage of intestinal 
tissue, apparently propelled forward through a 


motion similar to peristalsis. Delta is ejected 
from an opening; emerging into a large 
hemispherical room with a domed roof largely 
composed of organic calcites, and a floor 
constructed from a mixture of adipose and 
cartilage. Several items of furniture are 
present, as well as three large sphincter-like 
folds of skin placed on the other end of the 
room. The room is devoid of water.> 


Delta: Jesus! | just got pulled through the 
anomaly. Think it bruised my ribs. I'm in some 
kind of circular room. There’s a large chamber 
here, round. It’s made up of more the meaty 
stuff we saw outside, but it looks a lot fresher. 
Healthier, for lack of a better word. 


Epsilon: I’m going in with you. 
Beta: Following. 


<Alpha, Beta and Epsilon enter the anomaly, 
and are united with Delta. All three agents are 
ejected from the cavity.> 


Alpha: Oh, god, the floor’s all sticky. Going to 
take another sample, hang on. 


Beta: This place kinda looks like a house or a 
tent. Mattresses and tables. People must have 
been living here for a long time. Looks like 
they’ve been gone a while though. Damn, I’m 
glad | can’t smell anything in this suit. 


Epsilon: There’s a load of thaumic equipment 
too. Bolines, chalices, blocks of salt... 


Alpha: And a solid Hume signature behind 
that ‘anal flap’. 


Beta: Why is everything here so gross? First a 


clit, now a butthole. 


Epsilon: Get used to it. It's called "Deep 
Feeders" for a reason. 


Delta: Keep the comms clean unless it’s 
something worth saying. I’m checking the flap 
to the left. 


<Epsilon enters the opening left of the primary 
anomaly. The room ts clearly a large study, 
with several papers, scrolls and artefacts 
inside. He collects them and surveys the room. 
It appears to be well-lived in.> 


Epsilon: Nothing important in here. Some 
books we don’t care about, a shelf, a table... 
must've been at least twelve people living in 
this complex. 


Alpha: Done with the samples over here. I’m 
going through the other. 


<Alpha enters the cavity to the right. Behind it, 
there is a large corridor, with several similar 
but relaxed openings on either side.> 


Delta: Find anything? 


Alpha: Not much. I’m looking through the 
rooms, seems like it’s a whole bunch of bunk 
beds, spare clothes, the usual fare. This stuff 
looks recent. Modern-day recent, judging by 
the way the clothes are made. Do you think we 
could be in an active anomaly? 


Epsilon: No shit Sherlock. It’s an SCP. This 
looks more like a reclaimed anomaly, from 
where I’m standing. Seems the guests got 
pretty comfortable here. 


Alpha: There’s nobody in here where | am. 


I’ve taken some DNA readings, we'll see if the 
lab boys can get a fix on who was living here. 
Delta, any word on the stuff in the main 
chamber? 


Delta: I’ve got the Thaumic equipment lined up 
on a table over here. Some of this looks pretty 
badly made. Whoever was living down here 
came after the anomaly first showed up. They 
might still be here, for all we know. 


<Alpha and Epsilon re-enter the main 
chamber.> 


Alpha: Yeah, well, | think we'll be seeing them 
real soon. The sig in the last room’s reading 
locked, about 300 on the Kant counter. 


Epsilon: Is it moving? 


Alpha: No. It doesn’t seem to be aware, 
either. It’s just a blob of jumbled thoughts at 
the moment. It definitely can't see us, if that's 
what you're worried about. 


Beta: Here goes, then. 


<MTF Gamma-9 enters the primary anomaly 
chamber. The structure begins with a lengthy 
corridor that goes on for about fifty metres at a 
slight downward angle, widening out into a 
small cylindrical chamber primarily composed 
of cardiac tissue. Several skeletons are 
embedded in the wall, with the remnants of at 
least five different individuals visibly stuck on 
its surface. There is a podium in the centre of 
the room with a small heart on it, beating 
rhythmically. The room pulses in tandem to the 
same beat.> 


Delta: Well, at least we know what happened 


to the guests. 


Beta: We're not going to get mulched like 
them, are we? 


Epsilon: Not unless we’re stupid. And as far 
as our knowledge goes, these skeletons could 
be anyone's. 


Beta: The heart's definitely not human. The 
whole room’s shaking with it. Think we should 
take it back to the lab? 


Delta: Don’t touch it yet. We have no idea 
what might happen. Alpha, what do you think? 


Alpha: Looks safe enough. It’s not sentient, 
it's not even putting out that much EVE. All 
that energy’s internal. The best way | can 
describe it is as a sleeping type green. 


Beta: So it won’t hurt you? 
Alpha: Not on purpose. 
Epsilon: Whatever. I’m taking the anomaly. 


<Epsilon takes hold of the heart, and removes 
it from the pedestal. It is unattached and 
comes off cleany. Upon losing contact with the 
pedestal, the heart and room stop beating.> 


Delta: Shit. Might have damaged the anomaly. 
Well, what’s done is done. Have we all got 
what we came for? 

Alpha: Samples collected. 


Epsilon: | have all the study equipment. 


Beta: Carrying some of the tools from the 
main chamber. 


Delta: Sounds all good. Let’s go. 


<MTF Gamma-6 return through the opening, 
and begin to swim back to the SCPS-lago. 
Command reestablishes contact as soon as 
they leave the fissure. The mission is 
concluded without incident.> 


Post Action Report: 


MTF Gamma-6's mission was deemed a success. The removal of 
the ’heart’S from SCP-3391 resulted in no visible changes to the 
overall anomaly. The yellow substance surrounding SCP-3391 
dispersed into the ocean over several hours. Analysis of the fluid 
revealed it to be composed of various organic proteins and lipids, 
several not occurring in nature. Standard analysis revealed it to be a 
non-anomalous source of both organic compounds, as well as safe 
for ingestion during laboratory testing. Its concentration in regional 
waters was deemed low enough that no disinformation campaigns 
were necessary. 


The team recovered several items of interest, several of which have 
been catalogued below. Followup dives failed to rediscover the room 
that MTF Gamma-6 had entered, or any other features of interest 
within SCP-3391. Review of Gamma-6’s mounted cameras reveal 
the entry chamber to have likely been a containment vessel for a 
large Thaumic working, with various artefacts and faint inscriptions 
within the room having acted as dampeners for EVE rebound during 
various thaumic activities. 


SCP-3391-3: 


SCP-3391-3 is the object recovered from the central pedestal of the 
room found within SCP-3391. It is physically and molecularly 
identical to a non-anomalous human heart, excluding a lack of 
openings where the pulmonary veins and arteries would be present, 
with thick layers of cardiac tissue in their place. When placed near 
exposed muscular tissue+, SCP-3391-3 will begin to beat 
rhythmically, causing the exposed muscle to anomalously contract 
and relax at a similar pace. Testing has revealed it to have a weak 
compulsive effect on small mammals, increasing libido and appetite. 


Recovered Materials: 


Several written texts and items were recovered from SCP-3391, 
many of anachronistic design. In total, Gamma-6 recovered three 
scrolls, one book, one now catalogued anomalous object® and 
numerous generic objects associated with Sarkic§ rites, including 
a series of sacrificial knives, preserved human organs and carved 
runic tablets. One such text believed to be related to its origins has 
been placed below. 


Recovered Text Excerpt: "Red Instrumentations"’ 
+ Text Excerpt: Red Instrumentations 


On the fourth day our guide introduced us to a 
woman who he called a "Volutaar", a status of 
some respect in their culture. She did not offer 
her name and so | did not think it wise to ask. 
We departed at noon and followed her for 
many hours. | must admit | was growing 
impatient. The road we walked was frigid and 
barren of sights. | believed for a time that she 
was simply waylaying us but when | first laid 
my eyes on the prison of Nyasae8, such 
thoughts immediately fled my mind. 


A great pit had been dug into the earth, with 
stairs taller than the pyramids themselves 
stretching deep into the hollow. It took us until 
the moon was well over our heads to reach the 
bottom and even then my amazement did not 
cease. We saw men with eyes like cats, 
women with serpents’ teeth, dogs the size of 
camels and soldiers whose appearances | still 
cannot conjure to my mind. But they were not 
what we were there to see. 


Beneath the earth there were monsters. | have 
no doubt that if Set or Apophis were to be 
found on Earth, Nyasae is where | would see 
them. There were mounds of flesh that took 


countless forms, pools of deep red blood and 
insects the size of men that tore one another 
apart with a ferocity | have never seen. While | 
was looking at the latter the woman 
approached me and asked that | come with 
her. When | asked where to, she only smiled.
