(Human-like cry repeats, at a greater distance.) 


Konstantin: It’s also possible that it’s a civilian 
who got dragged in here. 


Yelena: Dammit. Alright. Zhenya and Zinaida, you 
two are in the back. Konstantin, we'll follow you. 


Konstantin: If you don’t already have safeties off, 
do it now. 


Leonid: Hey Command, just notifying you the 
ceiling’s dropping... pretty considerably in this 
direction. It might be a dead end. 


Yelena: That noise is coming from somewhere. | 
don’t care what it is that’s making it, but we're 
going to find it. 


(Kratkiy’s light reveals a large, shallow body of the 
same yellow fluid discovered by Team One, 
directly in front of the exploration team.) 


Konstantin: Looks shallow enough. Command, 
this stuff is safe? 


Command: Our boys are still running tests on it. 
It’s sticky, but it won’t harm you. 


Konstantin: We should be able to ford it. If the 
cave cuts off, I’ll let you Know and we'll turn 
around. 


(After approximately four minutes, the cavern 
increases in height and the body of fluid ends. 
Team members exit the fluid and wait for further 
instructions. Multiple diffuse noises can be heard in 
this cavern, most notably a repetitive scratching 
sound.) 


Yelena: Spread out. Weapons up. 


Konstantin: Command, this cavern is 
considerably larger than the last few we’ve been 
through. We've... I’m looking at the ceiling now, 
and | lose sight of it after about two meters. 


Command: I’m impressed you managed to find 
this place, but remember this isn’t in the original 
mission parameters. The last thing we need is you 
getting lost in there. 


Konstantin: Does anybody see an opposite wall? | 
don’t like not knowing how far this place goes. 


Yelena: Nothing over here. Zhenya, Zinaida, what 
about you? 


Zhenya: No wall, but there’s a pile of something on 
the floor where | am. Looks like... wood chips? 


Zinaida: Sorry, Yelena. | got — fucking shit shit 
shit! 


(Gunfire.) 
Yelena: Zinaida, come in! What just happened? 


Zinaida: ...| think it was a rat. I’m pretty sure | 
missed it. 


Yelena: Are you alright? 


Zinaida: It was up inside this thing, looking like it 
was — it was — adjusting parts before it ran, and — 
Yelena, can you take a look at this? | don’t know 
what the hell I’m looking at. 


(Teams Two and Three converge on Zinaida to 
reveal a large, intricate circular wooden structure 
with one side apparently winched open. Rows of 
wooden spikes are visible inside, covered in a dark 
substance presumed to be blood.) 


Dmitri: Holy hell. 


(Noises resembling human whimpering emanate 
from deeper within the cave.) 


Yelena: | can’t say I’m a fan of this situation. 
Command, |’m advising a strategic retreat. 
Whatever it is that’s in here, we don’t need to deal 
with it. 


Zinaida: There’s more of them. They’re 
everywhere. 


Yelena: The machines? Or the rats? 


Zinaida: Both. They’re all over the fucking place. 


No more 


« SCP-473 | SCP-474 | SCP-475 » 


(Zinaida’s camera displays over 20 wooden 
structures of varying shapes and sizes, covered in 
large rats. All are staring at the exploration team.) 


Konstantin: Go on! Shoo! 


(The rats start and scurry away. Several forms are 
observed within the wooden structures.) 


Yelena: Command, are you seeing this? There... 
there are bodies in some of these. 


Leonid: Probably a civilian from town. Poor sap. 
Kratkiy: Oh my god. 

Konstantin: What is it? 

Kratkiy: This one’s still alive. 


END LOG 


SCP-3667-2: 
Level 3/3667-2 clearance required. 
Input credentials 


SCP-3667-2 is the collective designation for a group of 
12,084 humanoid anomalies, discovered in SCP-3667 on 
30/10/2012 and relocated to Site-574 from 02/11/2012 to 
28/12/2012. Although the vast majority were discovered 
inside SCP-3667-3 instances, approximately 150 of all 
instances recovered were found either being transported 
within SCP-3667-1f instances, attempting to flee from 
SCP-3667, or being consumed by SCP-3667-1a or -1b 
instances. 


All SCP-3667-2 instances display anomalous limited 
regeneration capabilities, activated by the same 
molecule retrieved by MTF Chi-5 Team One during 


Exploration 3667-A, which is present in their 
bloodstream. Attempts at introducing the molecule into 
the bloodstreams of non-anomalous humans have not 
resulted in the same regeneration capabilities; further 
research is ongoing, but it is currently assumed that the 
anomalous regeneration is directly tied to the 
SCP-3667-2 instances, with the anomalous molecule 
acting as merely a catalyst. Despite this, it is still possible 
to terminate SCP-3667-2 instances through repeated 
use of force exceeding the rate of their regeneration 
abilities (approximately 4mm of tissue a day, slower for 
organs or bone marrow). 


Of the 12,084 SCP-3667-2 instances, 10,756 are perfect 
physical and genetic matches for former residents of 
Mirny within the last 50 years (the remaining 1,328 
instances do not correspond with any known person, 
living or deceased). Although all SCP-3667-2 instances 
claim to have lived their whole lives within SCP-3667,° 
sampling from suitable cadavers within the Mirny region 
have confirmed the match. Analysis of town records and 
the SCP-3667-2 population indicates that, in order for a 
deceased resident to result in a genetically identical 
SCP-3667-2 instance to form within SCP-3667, several 
criteria must be met: 


¢ Resident’s progenitors must have lived within 
Mirny town limits for at least two generations; 

¢ Resident must have been suspected by 
contemporary residents of: committing a crime 
(however, resident must not have been convicted), 
such as arson or pedophilia; lechery; avarice; 
homosexuality; or paganism. 

¢ With some exceptions, resident must have been 
affiliated with, or maintained close ties to, the Light 
of Five Heavens Russian Orthodox Church® and 
its founder, Sergei Guslyakov. 


Incursion: 


On 23/08/2014, after 41 separate explorations of SCP-3667 


mapping much of its interior, as well as capturing and containing 
instances of all known SCP-3667-1 species, a large (approx. 50m in 
height) porcine, previously unrecorded species of SCP-3667-1 
exited the sinkhole and proceeded to assault the MTF Chi-5 base 
camp, leading to 3 casualties and 20 severe injuries. Due to the 
instance’s possession of the same anomalous regeneration 
capabilities previously observed in SCP-3667-2 instances, as well 
as what superficially appeared to be an exoskeleton, on-site 
personnel were unsuccessful at termination attempts and instead 
called a strategic retreat to Site-574 to wait for reinforcement. Upon 
returning to the Mirny mine, Foundation personnel discovered that 
the SCP-3667-1 instance (classified as SCP-3667-1v) had 
destroyed much of the missile system perimeter and returned to the 
area directly in front of the sinkhole, where it remained unresponsive 
to further Foundation actions, including preparations for a 
coordinated round of air-to-ground drone strikes which eventually 
succeeded in terminating it. 


In response, Site-574 Director Ndeye Bocoume and Sakha Republic 
Regional Administrator Angelina Mikhailova issued a joint request to 
the O5 council, arguing that given the continued danger to 
Foundation personnel and Mirny residents posed by large, hostile 
SCP-3667-1 instances, as well as the number of SCP-3667-1 
instances already kept in containment, MTF Chi-5 and additional 
Foundation reinforcements should proactively terminate all hostile 
SCP-3667-1 instances within SCP-3667 and attempt to secure the 
cooperation of sentient instances where possible. 


After 8 separate Ethics Committee hearings, O5 approval was 
granted on 02/13/2015. MTF Chi-5 Teams One through Three, as 
well as MTF Zeta-9 (“Mole Rats”) Teams Two through Four, began 
invasion preparations on 02/22/2015 and entered the anomaly on 
04/07/2015. 


Incursion Report 3667-C 


Incursion team mobilizes at Site-574 at 0500 
hours. MTF Chi-5 Team Two and MTF Zeta-9 
Team Four each drive AFVs, for use in encounters 
with additional SCP-3667-1v or other SCP-3667-1 


instances. The remaining four teams travel on foot. 
An additional MTF personnel, henceforth referred 
to by her designation Perevodchik, provides 
translation between MTF Chi-5 and MTF Zeta-9; 
unless otherwise specified, Perevodchik’s 
translations are omitted from the log for sake of 
brevity. All MTF personnel have been armed with 
ordnance and small explosives, in addition to 
antidemonic kinetics’ and incendiary devices 
stored in the vehicles. 


Echo: Mole Team Two, reporting in — hey, P, is 
Command one of ours or theirs? 

Command: I’m not sure what you mean. 
Perevodchik: Command is local. 


Echo: Huh. I’d prefer someone | don’t need a 
translator to understand, but... P, tell Command 
we’re here. 


Juliet: Z-9 Team Three. We’re all here. 


Anna: Quite a party today, isn’t it, Command? A 
shame we'll all need Perevodchik to communicate. 


November: Better hope it’s a quiet trip today, then, 
P. Otherwise these boys and girls will be crowding 
all over you. 


Perevodchik: | guess that would make me 
something of a celebrity, then. | always wanted to 
bea VIP. 


(Laughter.) 
Konstantin: Team Three here. 


Yelena: And last but not least. | think that’s 
everybody, Command — are we cleared to go? 


Command: You're cleared from up here. Proceed 
when you're ready. 


Konstantin: Alright. Zeta-9: before we enter the 

anomaly, | just want to warn you that there’s a bit 
of disorientation when you cross over. You'll feel 

dizzy... 


Oscar: Dizzy, a little nauseous, everything’s dark 
and you lose contact with Command for 
approximately three point zero five seconds? 
Yeah, we've been there, done that. It’s bog- 
standard for dimensional skips like this. Besides, 
we’d already read through all your exploration logs 
by the time we touched down. We know this place 
inside and out. 


Foxtrot: SSUDS2. Stable, Stationary, Unaided, 
Delayed, Safe, Two Way. 


Gregory: | knew that. 


Oscar: In any case, here’s the plan once we get 
inside. Lima here’s run analysis on the interior 
schematics of this place and determined that most 
of the larger stone structures tend to congregate 
around the river systems. That’s where we'll find 
the big critters. Each team here will take a major 
river — | trust you know where they are by now — 
and clear it out, end to end. If you need backup, 
radio one of the teams with the van. Command will 
be looking out for you as well, assuming you speak 
their language. Questions? 


Vasily: | wasn’t aware we had discussed this. 


Oscar: The other Moles and | came up with it on 
the plane ride over. Given these entities’ 
behaviour, it’s the best strategy if you want to keep 
this clean and quick. 


Konstantin: With all due respect, | don’t think you 
know this place like we do. Chi-5 — we're all Mirny 
boys and girls. We grew up around the mine. We 
were there when things started coming out of it, 
and we’ve been down there forty-odd times by this 
point. We can handle ourselves. 


Oscar: With all due respect, | don’t think you can. 
I've watched the tapes. I’m glad to see your ankle’s 
doing better, Gregory. Be careful on those hills, 
won't you? 


(Twenty seconds of radio silence.) 


Oscar: Look, I’m sorry. | know this is your home 
turf. But you’ve got to trust us on this one. This is 
what we get called in for. 


Yelena: Command? 


Command: Go on ahead, Oscar. Let’s get this 
over with. 


(Incursion team enters SCP-3667 without any 
further incident. As per Oscar's instructions, each 
team is assigned to a major river system and begin 
a sweep for hostile entities. The rats observed near 
SCP-3667-3 instances are more present, being 
sighted by several teams; however, none approach 
personnel.) 


Juliet: These rats a 3667-1? 


Zhenya: We're pretty sure they're just normal rats. 
There’s not as much weird shit in here as you'd 
think. 


Lima: Where’s all the creatures, then? They’re 
sapient, aren't they? 


Vasily: Some of them are. Most aren't. 


Oscar: We'll find the non-sapient ones wherever 
they happen to be. If it's the sapients we're after, 
though, they might be coordinating... ahh, there’s 
one. 


(Aggressive gibbering and the noise of 
antidemonic kinetics being fired can be heard.) 


Oscar: Squishy little fuckers, aren’t they? 
November: There’s some in your hair. 
Oscar: What’s that? 

Perevodchik: She’s saying the coast is clear. 


Oscar: Ever seen one like that before? Weird little 
guy, drinking out of the stream. Looked like a 
skinny little kid with a big, drooping head. Is that 
one sapient, do you know? 


Boris: Sounds like a 3667-1m. Sapient, but just 
barely. | wouldn't lose any sleep over it. 


Yelena: That’s one monster down out of... what, 
hundreds? There’ve been times where we couldn't 
walk around this place without sneezing all over a 
colony of 3667-1 -whatever-the-fuckers. Where did 
they all go? 


Oscar: Chi-5, how many of these rivers have you 
explored end-to-end? 


Konstantin: The big ones, you mean? Uh, most of 
them. I’d say... 80%. 


Oscar: (Opening supply packs in AFV.) There’s a 
map of this place in here somewhere, isn’t there? 
Here. Konstantin — it’s Konstantin, right? 


Konstantin: Yes. Why are we stopping? 


Oscar: If | showed you the rivers, here, on a map, 
would you be able to point out the unexplored 
ones? 


Konstantin: These... three. Yes, | think that’s all. 


Oscar: That’s Zeta-9 Teams Two and Three, Chi-5 
Team Two. 


Konstantin: Chi-5 Team One. 


Oscar: Right. You're right. Moles Two and Three, 
Chi-5 One, come in. What’s your position? 


Juliet: This is Team Three. We've reached the end 
of the river. It all drains into a sinkhole — we’ve 
thrown a couple of torches in, but the bottom’s 
pretty shallow. Honestly, Oscar, | don’t think 
there’s anything here. 


Echo: Mole Two here. When we got your 
message, Foxtrot scouted out ahead, and he says 
the river goes into a crack in the wall the size of a 
mouse. Too small for us, or anything else here, to 
squeeze through. We haven't seen a single 
creature on our whole jaunt so far. 


Konstantin: How about you, Team One? 
Gregory: We, uh, we found a cave. 


Anna: Konstantin, the river flows through a 
passageway here that leads into a chamber... it 
might be bigger than the one you're in now. 
There’s a lot of artificial activity present here. 
Bricks in the walls, bones and garbage — we found 
a couple of 3667-3 instances, but no people in 
them so far. Vasily keeps saying he can hear 
noises up ahead. 


Gregory: It’s a really big cave. 


Konstantin: You think that’s it? 


Oscar: Definitely. I'll call the other teams to 
rendevous at — well, here, you do it. 


Konstantin: That’s not necessary. 
(Two minutes of silence.) 


Oscar: Look, we're sitting in a cave in Hell in 
Russia, and | don’t want to have to ask again. 


Konstantin: Thank you. 


Oscar: I’m not staying in here any longer than | 
have to. 


Konstantin: Zeta-9 Teams Two, Three, Four, 
Chi-5 Teams Two and Three, we’re rendezvousing 
at Team One’s location. | want everyone there in 
five minutes, tops. 


Yelena: Understood. 
Echo: On our way. 


Konstantin: What do you think we'll find in 
there? 


Oscar: | don’t know. Nothing good. 


Konstantin: Anna, hang on and wait for us. We'll 
be there soon. 


Anna: The river looks different here. It’s... 
bubbling. 


(Chi-5 Teams Two & Three and Zeta-9 Teams Two 
through Four rendezvous with Chi-5 Team One 
without further incident.) 


Yelena: Anyone seen any creepy-crawlies so far? 


We haven't. 


Juliet: | think it’s just Konstantin and Oscar who 
have. 


Anna: Command, are you getting this? | don’t 
know if this river’s made of the same stuff we 
sampled before.
