Stage 1: A sheep's liver is introduced to SCP-361. 
Vocalization: Welcome to HarusCo! Your sacrifice is 
very important to us! For Tinia the Thunderer, please 
perform a horizontal incision on the offering. For Aita of 
the Underworld, please perform a vertical incision. For 
Maris, lightly cover your offering with the ash of a dead 
warrior related to you by blood. 


Stage 2: A horizontal incision is made. 

Vocalization: You have selected Tinia. For your weekly 
meteorological divination, please singe your offering over 
an open flame for five seconds. For warning bolts, 
please place a green olive on the altar. For 
beseechments and beneficial interventions, please 
attach a written consent from the Consulate Gods. For 
Catastrophes, please remove the head of an adult ox 
and hold. 


Stage 3: The liver is singed over an open flame. 
Vocalization: You have selected weekly meteorological 
divination. For your local forecast, please perform the 
seven sacred rites of Tinia while avoiding the anger of 
the mildew spirits. For forecasts for other areas, please 
perform the rites upon a boat of three masts or more. For 
a marital forecast, please consult with your local 
priestess of Uni. 


Stage 4: Researchers were unable to comply with the 
instructions in the given time frame. 

Vocalization: No input was received, this sacrifice will 
be disconnected. Thank you for using HarusCo, Rasna's 
#1 divination and deistic petition service for more than 
two thousand years! The Gods are looking forward to 
your next call! 


[SCP-361 enters inactive state] 


Addendum SCP-361-A: In order to examine the limits of SCP-361's 
ability to alter the language and tone it uses to interact with its user, 


cessation of mission- 
Bravo: Wait a second- 


Foxtrot: —on the edge of the nothingness, 
inches from oblivion. There's a... there's a 
sickness in my mind that | know can't be 
cured. Beyond me is only blackness, and a 
single pair of dark eyes- 


Alpha: What? What are you saying? 


Command: Dive team, we’re going to pull you 
back in immediately, we have reason to 
believe that— 


Alpha: Barry? Is that you? How can it be? | 
shoveled the dirt during your— 


Bravo: | can hear something over there, 
Alpha, your light, get your fucking— 


Foxtrot: —silence, only silence, my 
consciousness coming undone and only and 
only and only- 


Command: Dive team, something is moving 
toward you, repeat, something is moving 
toward you, prepare to return to- 


Alpha: Ah, this is shit. | can’t see. How far are 
we from the- 


Bravo: It’s right there! It’s right there! Fuck! 
What are you both doing? Fuck! 


Foxtrot: —and only the eel remains. 
Radio silence for twenty seconds. 


Command: Alpha? 


Radio silence for thirteen seconds. 


Command: Alpha? Bravo? Foxtrot? Do any of 
you hear us? 


Bravo: (Unintelligible) 


Command: Oh, thank God - Bravo, you need 
to speak up, we can't— 


Bravo: Shhhhhhhh. 
Radio silence for ten seconds. 


Command: Something has bound up the 
winch between you and us, we can’t— 


Alpha: It’s opening its mouth. 

Bravo: It's so dark, there’s— ah- 

Foxtrot: Where am |? What— 

Alpha: Barry? How can it be? | shoveled dirt- 


Bravo: Mulhaney... swim, get away, there’s 
only darkness, swim— 


Foxtrot: Only- 


There is suddenly tension in the tether 
attached to the Stravinsky. O-9 Foxtrot’s radio 
goes silent. There is the sound of a struggle 
through the other two radios. 


Command: Foxtrot? Foxtrot? Alpha? Bravo? 
Talk to me, stay calm, what happened? 


Bravo: It ate him, fuck, he’s gone, it took him 
whole, he— goddammit, Alpha, what are you 
doing? 


Alpha: Alpha? 


Bravo: Cut the fucking goddamn tether Alpha, 
it’s pulling us in! 


Alpha: Who? 
Bravo: Fuck! 
Alpha: (Silence) An— 


Total radio silence for 30 seconds. Tether 
attached to Stravinsky is pulled free from its 
moorings and disappears. 


Command: Alpha, Bravo, do you copy? 
Radio silence for five seconds. 
Command: Alpha, Bravo, do you copy? 


Bravo: This is Bravo, I’m... I’m floating in the 
dark. | can see shapes moving through the 
fog, but they’re hard to make out. | cut my 
tether, Alpha wouldn’t— | think he’s gone. | 
don’t see his light anymore. 


Command: Acknowledged. We're coming to- 


Bravo: Hang on, just let me think for a 
second... cognition, this thing, it doesn’t work 
around it. Your brain can’t form thought, 
(static) it hurts, it’s like dying, and— 


Command: Bravo, do you have eyes on the 
entity? 


Bravo: It’s in my head, guys. Coiled up in 
there like a snake, and something about it is... 
caustic. (Pauses) | can see it, just in front of 
me. It’s not doing anything, it’s... it isn’t 
moving. Just hanging there, with its mouth 
open. | think it’s finished eating. (Pauses) That 
fluid is seeping through the skin around its 


head, about a meter back. Just looking at the 
stuff is making me... like the room is spinning. 
| feel nauseous. My head isn’t working right. 
(Laughter) There's an abortion under the 
floorboards, and another in the si— wait, this is 
wrong, that wasn't me. Who said that? 


Bravo: My... I’m going to collect a sample, 
hang on. 


Command: Bravo, we’re going to send out a 
crew to get you, just hold on. 


Bravo: Oh no, don’t do that. Not... you have to 
be trained to not feel the things I’m feeling, 
otherwise it will get into you. Maybe it will 
anyway, who knows. It feels like the end of the 
world down here, fellas. My heart is really 
going off the charts, and | think I’m dying. Just 
— (Pauses) | got a sample. I'll attach it to one 
of those little balloons and let it float up. You'll 
be able to get it later. Don’t soend too much 
time around that stuff, it... it doesn’t... your 
mind... it... (Quick, heavy breathing) 


Command: Bravo? 


Bravo: | think I’m dying. I’m dying, | know I’m 
dying, this is it. | just want to get away from 
here. You know, it occurs to me... (laughs 
quietly) don’t send anyone else out here. It’s 
so dark. 


Command: Bravo? 


Over the next half hour, the SCPF Stravinsky attempted 
to approach O-9 Bravo, with no success. Command 
continued to attempt to communicate with O-9 Bravo, but 
Bravo grew increasingly unintelligible, before eventually 
going completely silent. Bravo's radio stayed active over 
the next three days, and intermittent breathing could be 


heard until the radio ceased functioning. 


Addendum 3000.2: Atzak Protocol 


This protocol dictates certain interactions 

with a CLASS VIII COGNITOHAZARDOUS 

ENTITY, SCP-3000, and as such is LEVEL 
5/3000 CLASSIFIED. 


Preface: The following protocol was 
developed in conjunction with researchers 
from Site-29 and Site-50, as well as 
researchers stationed at Site-151. Some 
sections may have been redacted to remove 
material above this classification. Adherence 
to this protocol is required for all personnel 
assigned to Site-151, as well as all personnel 
assigned to the SCPF Eremita. 


Abstract: The 151-HOLLISTER ATZAK 
PROTOCOL has been developed and 
implemented to create a strategy for the 
management of the Y-909 chemical compound 
excreted by SCP-3000. 


Protocol Information: The Y-909 compound, 
originally discovered by the late Dr. Adam 
Hollister, is a critical component in several 
modern and experimental amnestic 
compounds. Specifically, the following 
amnestics now contain a refined version of the 
Y-909 compound: 


¢ Class-A (2016 variant) 
¢ Class-D (2016 variant) 


¢ Class-E (2016 variant) 


* Class-X (2017 variant) 

* Class-XX (2017 variant) 

* [REDACTED] 

* [REDACTED] 

¢ Atzak-Class Experimental Compound 
* Foster-Class Experimental Compound 
* Ellipse-Class Experimental Compound 


The inclusion of the Y-909 compound has 
shown a marked increase in the stability and 
long-term effectiveness of the aforementioned 
amnestics. Overall, amnestics utilizing Y-909 
break down 78% slower than their standard 
counterparts in cold storage, and 52% slower 
than their standard counterparts at room 
temperature. 


Additionally, individuals administered an 
amnestic regimen utilizing Y-909 show a 
marked increase in suggestibility, memory 
clearance, and a significant decrease in 
additional side-effects (such as nausea, 
vomiting, bowel distress, blurred vision, 
headaches, insomnia, heart damage, and 
others). Individuals treated with these 
amnestics expressed significantly fewer 
intrusive memories as those without Y-909, 
with some individuals exposed to experimental 
compounds expressing no intrusive memories 
whatsoever, even at the 5 and 10 year marks. 


Due to the effectiveness of these treatments 
with the addition of Y-909, the continued 
inclusion of this compound is essential to 
modern Foundation amnestic application. 


Reliance on the continued use of Y-909 
necessitates its collection for the foreseeable 
future, as a synthetic version of the compound 
has not yet been discovered. 


As such, this protocol dictates the way this 
compound is collected off of SCP-3000, and 
the way personnel are to interact with 
SCP-3000. Below is a brief framework of the 
procedure, and detailed information can be 
found in the full Atzak brief: 


¢« Members of MTF Epsilon-20 "Night 
Fishermen" are to prepare a subject for 
deliverance to the feeding site. One 
individual D-Class subject is to be 
administered a sedative, and equipped 
with a high-pressure diving suit. The 
subject is then to be tethered to an 
underwater ROV within the aft airlock. 
The airlock is to be flooded, and the 
subject is to be towed by the ROV 
towards the feeding site. Upon reaching 
the feeding site, the ROV is to 
disconnect its tether, and return to the 
Eremita. 


Throughout this stage, SCPF Eremita 
should monitor SCP-3000's position, 
and adjust course if the entity begins to 
move away from the feeding site. 
Mission command will provide additional 
instructions during this phase if 
necessary. 


Personnel on-board the SCPF Eremita 
are to monitor SCP-3000 during feeding 
sessions. During this time, no 
personnel are permitted to leave the 
Eremita without authorization from 
mission command. 


¢ Ata point after the total consumption of 
prey, SCP-3000 will begin to excrete 
Y-909 near the foremost section of its 
body. 


Specialized teams of deep-sea divers 
are to exit the SCPF Eremita through the 
aft airlock and approach SCP-3000. 
Collection of Y-909 must take place 
during SCP-3000's "digestive" period, 
which is currently believed to be roughly 
two and a half hours after consumption 
of prey. Teams must return to launch 
craft before the end of this period. 
During this period, the typical effects of 
SCP-3000 are less severe, though 
Command should continue to monitor 
these teams for damage to their 
cognition. 


After collection of Y-909 is complete, 
personnel are to transfer the collected 
substance to secure containers before 
returning to the surface. The mission 
administrator onboard the Eremita is to 
monitor the substance throughout 
transport. 


Addendum 3000.3: Psychological Evaluation 


Note: On / 09, Level 3 Researcher Venkatraman 
Krishnamoorthy attempted to exit out the Eremita’s aft 
airlock without diving equipment, but was quickly 
restrained and the airlock cycle aborted. Despite having 
a CRV of 26, and having not displayed any previous 
signs of depression or suicidal attempt prior to his 
assignment aboard the Eremita, Krishnamoorthy was 
interviewed by staff clinical psychologist Dr. Anand 
Mannava to acquire a better understanding of 
SCP-3000's potential effect on his psyche. 


[BEGIN LOG] 
Mannava: Hi Venkat, how are you feeling? 
Krishnamoorthy: Unwell. 


Mannava: That's what | hear. Do you want to 
talk about what happened today? 


Krishnamoorthy is silent. 


Mannava: We don't have to, if you don't want 
to. We can talk about something else. 


Krishnamoorthy: I'm tired, Anand. 


Mannava: | understand. This assignment has 
been stressful on all of— 


Krishnamoorthy: It's not, no, it isn't the 
stress. I've done this before, I've been on... | 
don't actually know if I've done this before. 


Mannava: You have. 


Krishnamoorthy: | don't remember it. Any of 
it. I've been getting these out of context 
feelings, like my body reacting to reflexes it 
didn't know it had. Everything is so 
disconnected, and trying to keep it together 
is... I'm just tired. 


Mannava: When did you start feeling this 
way? 


Krishnamoorthy: How long have we been 
down here? | don't remember. | don't know 
when, | honestly don't. | wish | could tell you 
more than that, but | have nothing. | look to 
that place in my mind and there's something 
else there— or sometimes nothing at all. 


Mannava: What do you mean, something 
else? 


Krishnamoorthy: I've been having other 
peoples’ dreams, Anand. | see faces | don't 
recognize, places | know I've never been... or 
maybe | have. | don't know. How can | know 
what is real or not, when | can't trust my own 
mind? 


Mannava: Well, maybe | can help you with 
that, Venkat. We can go over things you think 
you've forgotten, and | can— 


Krishnamoorthy: Don't patronize me. | know 
you've felt it, Anand. Your mind gets hazy. 
Parts of you start to slip, your memories grow 
faint, fading in and out until they're gone, or 
worse, replaced. You see pasts that aren't 
yours, experiences that you never lived. You 
start to become other people, or... nobody at 
all. 


Mannava: Venkat, please. I'm just trying to 
help. 


Krishnamoorthy: Do you even know my work 
before we met? Come to think of it, | don't 
even remember how we met. | know your 
name, know that you're a psychologist, but are 
we friends? Are we brothers? | don't know how 
| know you. We work together, | know that. | 
still have that. But other things, they come and 
go. | don't know if | am married, or have 
children‘. 


Mannava: | see. 


Krishnamoorthy: And that... that isn't the 
worst of it. | know this is happening to me, | 
know that my mind is coming apart. But there's 


a subject with a similar cultural origin to SCP-361 was required. For 
that purpose, a request for interaction between SCP-361 and 
SCP-1510, the persona of which originates from the same general 
area and time period, was made and accepted. 


Test 361-B 


Stage 1: Subject D-1510-104, wearing SCP-1510, 
introduces a sheep's liver to SCP-361. 

Vocalization: SCP-361 vocalizes in Classical Latin, the 
language spoken by SCP-1510-1. The instruction is 
translated to "Son of Romulus, speak the words thy 
father taught you, and your watcher will speak, his words 
carried by our spirit.” 


Stage 2: SCP-1510-1 chants several phrases in Latin, 
later identified as an oath to Mars Gradivus. 
Vocalization: SCP-361's instruction is translated to 
"Place the aspect of your watcher at his feet, so he might 
see your altered form." 


Stage 3: SCP-1510-1 requests an open flame. He is 
given a camping gas lamp. SCP-1510 places the lit gas 
lamp at the feet of the table SCP-361 is placed on. 
Vocalization: SCP-361's instruction is translated to 
"Speak the duty of your watcher, so he might judge your 
worthiness.". 


Stage 4: SCP-1510-1 speaks a Latin phrase, later 
identified as Mars Gradivus' oath: to guard, preserve, 
and protect the state, the peace and the senate. 
Vocalization: SCP-361's instruction is translated to 
"Show your watcher that you do not stand alone; Does 
he who guards your left carry with him your watcher's 
conviction?" 


Stage 5: SCP-1510-1 requests one of the supervising 
researchers to enter the room and touch SCP-361. 
Request granted. 

Vocalization: SCP-361 speaks in a different voice, still 
in classical Latin: "Courage, Publius. This too shall pass. 


something else in there, too. Something rising 
out of the... out of the smoke of my smoldering 
consciousness. That eel. 


Mannava: The eel?
