After the events of Incident 2474.1, the personal records of Dr. 
Simonis were seized and reviewed by Foundation researchers. 
Documentation shows that Dr. Simonis continued working in the 
aerospace industry for several years after the discovery of 
SCP-2474, before abruptly resigning from the USA-88 GPS satellite 
launch mission staff. Personal correspondence involving Dr. Simonis 
at this time documents a marked change in personality, with 
personnel files noting unspecified erratic behavior. This is believed 
to be attributable in part to SCP-2474 exposure. 


Public records concerning Dr. Simonis indicate that he divorced in 
1995, and purchased several acres of land in rural Michigan later in 
the year. After the land purchase, the only documentation related to 
Dr. Simonis is correspondence from various publishing houses and 
internet-based literary services. During these years, Dr. Simonis 
repeatedly attempted to publish a short story entitled The Threshold 
and the Nineteen and On, which was uniformly rejected by all 
recipients. Dr. Simonis self-published this story on several occasions 
in several different forms of electronic media. No evidence exists 
that the story was read by any individuals apart from Dr. Simonis. 
Access to The Threshold and the Nineteen and On is currently 
exclusive to Manu Thirteen per A3 protocol. 


Dr. Simonis was declared deceased by the State of Michigan Vital 
Records Office in 2037 after requests by county-level officials to 
discharge his estate to his legal heirs. The death certificate of Dr. 
Simonis lists no cause of death, as no remains were ever recovered 
after investigation of his Schoolcraft County, Michigan residence and 
the vicinity. 


Addendum 2474.2 - Incident 2474.1 
INCIDENT REPORT 
DATE: 23 November 2142 


ANOMALY INVOLVED: SCP-2474 


CASUALTIES: Six staff injured: 


« Lead Researcher Seung Jae Rim 
¢« Researcher Jens Halvorsen 

¢ Researcher Anjali Mannava 

¢« Researcher Jacob Fenton 

* Technician Leonard Gryboski 

¢ Technician Ishii Kiemon 


PROPERTY LOSS: N/A 


INCIDENT SUMMARY: Research team analyzing 
imaging results from recent Harbinger 3 clandestine 
satellite mission in low Venus orbit encounters image of 
unknown, presumed anomalous structure present in 
northern Venusian hemisphere. Approximately three 
hours after filing report for initial SCP classification, all 
members of research team begin exhibiting signs of 
distress. Lead Researcher Seung becomes 
unresponsive to all stimuli, while Researcher Fenton and 
Technician Ishii report visual and auditory hallucinations. 
Remaining team members report intense sensation of 
intrusive thoughts. All personnel immediately 
quarantined under emergency cognitohazard response 
procedures. 


RESPONSE: SCP-2474 receives official classification 
and is listed as Designation A3 cognitohazard. Lead 
Researcher Seung receives diagnosis of permanent 
vegetative state and is moved to long-term intensive care 
facility. Researcher Fenton and Technician Kiemon 
receive ongoing course of sedatives and antipsychotics 
to control anomalous symptoms. All staff currently being 
evaluated for therapeutic and counseling needs upon 
expiry of A3 quarantine. 


Addendum 2474.3 - Research Log 2474.17: Staff Observations 


Foreword: Exposure to SCP-2474 is believed to have provided 
affected research staff with an unknown relationship to an as-yet 
undefined race of entities, believed to reside at the site of the 


anomaly. Attempts to ascertain the nature of these entities are 
ongoing. 


In an effort to understand more about the nature of the anomaly, 
interviews of the responsive staff from Incident 2474.1 were 
conducted between 8 January 2143 and 17 March 2143 by the 
Manu Thirteen Artificial Intelligence System, the system having been 
demonstrated to be immune to the cognitohazardous effects of 
SCP-2474. Many individual and group interviews were conducted in 
order to determine the nature of SCP-2474. The following are 
transcripts of those interviews that have provided significant data 
regarding SCP-2474. Portions of these transcripts have been altered 
by Manu Thirteen in order to remove potential cognitohazards and 
have been noted. 


Manu Thirteen: You described a sensation of being 
made to think in a way alien to your consciousness, 
Anjali. Would you mind describing more about these 
thoughts? 


Researcher Mannava: Could you do the hologram 
thing? | don't like talking to an empty room. 


Manu Thirteen: Certainly, Anjali. [MANU THIRTEEN 
PROJECTS HOLOGRAPHIC AVATAR IN CHAIR 
OPPOSITE RESEARCHER] Would you mind describing 
more about these thoughts? 


Researcher Mannava: It was...it wasn't neatly defined. 
Not like, images or clear phrases or anything neat. It was 
all kind of muddled together, but it was like | wasn't in 
control of it. Does that make sense? 


Manu Thirteen: No. 
Researcher Mannava: Well, um... 
Manu Thirteen: Joking. Yes. Please continue. 


Researcher Mannava: ...anyway, it would be something 
like a collection of sensations, or the memory of 


sensations, and there would be words in it, a little. Like, | 
would be cognizant that | should be feeling an intense 
heat on my face, and | would be thinking of the distance 
between two parallel lines, and the word "foomu2" would 
echo around in it. 


[RESEARCHER MANNAVA PAUSES] 


Researcher Mannava: It was overpowering. Nothing 
else could be in my head while that was happening. | 
didn't know to be afraid, or to think that | was being 
violated somehow. And you know what's weird? 


Manu Thirteen: What is weird? 


Researcher Mannava: Thinking back on it, it's...it's not 
happening again when | remember it, but | feel some of 
the same things. Well not feel, but almost feel, like 
remembering something that just happened to you. 


Manu Thirteen: That is weird. That is consistent with 
narratives provided by Gryboski and Halvorsen. 


Researcher Mannava: It's...it's becoming different, now. 
Just talking about it. It's TRANSCRIPT ALTERED FOR 
READER PROTECTION It's frustrating. Like I'm almost 
remembering something but not quite. 


Manu Thirteen: That is weird. That is not consistent with 
narratives provided by Gryboski and Halvorsen. 
Manu Thirteen: Have the images stopped? 


Technician Ishii: Is this how things are for something of 
your kind? An error of programming, and you perceive 
differently? 


Manu Thirteen: What do you mean? 


Technician Ishii: It is still there. It blends in when | stare 
at the wall but when | close my eyes it becomes crystal 


clear. 
Manu Thirteen: The image of the white face, you mean. 


Technician Ishii: The medication blurs it. It clouds my 
mind, but it blurs that face too. It cannot look me in the 
eyes anymore. A small mercy. 


Manu Thirteen: The analytical team tells me they don't 
believe it to be a face. That your mind constructs it to be 
a face in order to be recognizable. 


Technician Ishii: Damn them and damn you. | know 
what | see. | know the difference between things like 
streaks of black light that sound like wind when | focus 
on them and a face. 


Manu Thirteen: Do you want me to request an increase 
in sleeping medication? Your irritability is slightly above 
baseline. 


Technician Ishii: That does no good. The images are 
fixed in my dreams as well. 


Manu Thirteen: What about TRANSCRIPT ALTERED 
FOR READER PROTECTION 


Technician Ishii: TRANSCRIPT ALTERED FOR 
READER PROTECTION 


Manu Thirteen: Do you think it's a separate entity, a life 
form, what you're seeing on these occasions? 


Technician Ishii: This idea of separateness. It's foreign 
to this thing. A smaller part of the whole, but the whole 
isn't in one piece. This is not like life as we know it. 


Manu Thirteen: Some of the others have described 
specific emotions associated with the hallucinations. Has 
this changed for you? 


Technician Ishii: | feel hope. | feel hope, but it is the 


The fireproof safe was found to be ineffective in containing 
SCP-273. Severe corrosion damage to the interior and hinges of the 
safe led to breach of containment, followed by the resumed revival 
of SCP-273. 3 kg of raw pork was left in the room, and the door 
secured. Upon awakening, SCP-273 appeared disoriented, but 
consumed the offered meal as expected. SCP-273 then requested 
to return to its original containment. As said enclosure has since 
been repaired, this request will be carried out immediately. 


Addendum 273-03-2: SCP-273's activity has changed drastically 
since the death event. It rarely leaves the private partition of its 
enclosure except to feed, and refuses to speak. Surveillance using 

shows that SCP-273 barely moves when on its own, either 
sleeping or sitting against one wall. It shows classic signs of 
depression, despite having no prior indications of such a condition. 
Recommending close observation for any additional changes in 
behavior.

hope of something else. Something that is not me. | find 
that disturbing. 


Researcher Halvorsen: | don't like doing this at the 
same time. 


Manu Thirteen: Being in your presence has brought a 
marked decrease in Jacob's symptoms. This is a 
potential breakthrough in understanding SCP-2474. 


Researcher Halvorsen: Yeah, | get that. | still don't like 
it. My skin is crawling. | feel like someone's standing 
behind me ever since | came into this room. 


Manu Thirteen: | have been told my presence can have 
that effect. 


Researcher Halvorsen: No, that's different. 
Psychological. This feels physical. 


Researcher Fenton: [HUMMING UNDETERMINED 
TUNE] Pi bracket theta prime over gamma...pi bracket 
theta prime over fifteen point eight three eight...pi 
bracket theta prime over fifteen point eight three eight to 
the eighth power... 


Manu Thirteen: This is the most intelligible Jacob has 
been since the initial incident. 


Researcher Halvorsen: That's not intelligible. That's not 
even math. 


[RESEARCHER FENTON CONTINUES HUMMING IN 
BACKGROUND] 


Manu Thirteen: That has yet to be determined. Leave 
the math to me, Jens. [LAUGHS] 


Researcher Halvorsen: Yes, you've a point there. 
Jacob. Jacob, it's me Jens, do you recognize me? 


Researcher Fenton: [FLINCHES VIOLENTLY AWAY, 
CONTINUES HUMMING] Pi bracket theta prime over pi 
bracket equals three...Pi bracket theta prime over pi 
bracket equals two... 


Manu Thirteen: Jacob hasn't attempted to flee from a 
nonexistent stimulus for three consecutive hours. This is 
really a noteworthy departure. 


Researcher Halvorsen: [PUTS HANDS OVER FACE] 
Ah, god it's bright all of a sudden, hold on, he's going to 
say- 


Researcher Fenton: One...one two one...one three one 
two... 


Researcher Halvorsen: ...yeah, that. And now it's going 
to be "one three one over theta prime." 


Researcher Fenton: One four one two...one three one 
over theta prime...one three one over pi... 


Manu Thirteen: Fascinating. 

Researcher Halvorsen: That's not the term | would use. 
Manu Thirteen: You are speaking for the group again, 
Anjali? 

Researcher Mannava: Yes. 


Manu Thirteen: You are speaking for the group, Anjali. 
Like last time, | am going to ask you to reflect upon the 
influences you felt during the incident. And like last time | 
am going to ask Anjali to describe the commonalities that 
develop as you think. 


Technician Gryboski: Roger. 


[FORTY-SEVEN SECONDS OF SILENCE] 


Researcher Mannava: It feels like it's about twenty 
minutes in the past. Does that make sense? 


[TECHNICIAN ISHII AND TECHNICIAN GRYBOSKI 
NOD ASSENT] 


Researcher Mannava: But, we're not waiting in the 
anteroom for the experiment to begin. We're doing 
something else. 


[SLIGHT PAUSE] 


Researcher Mannava: We're...in a circle of some sort, | 
don't understand- 


Technician Ishii: It is another language. We are 
speaking in something that sounds...not unlike Ainu. It is 
Eastern, of some sort. 


Researcher Mannava: Right, and there's...a dozen of 
us, maybe more, | recognize us but we're not really 
there. 


Technician Gryboski: Dozen at least. Maybe more. 


Manu Thirteen: Are there any unifying concepts? 
Commonalities? 


Researcher Mannava: No, no...strangely not. Like that's 
the point, almost. Everyone's kind of all over the place. | 
feel like I'm being put into a sack. | feel that the notion of 
distance is ceasing to hold. The person next to me is 
three light-years away. 


Manu Thirteen: [LAUGHS] 


Technician Ishii: No, no that is so. Something is 
leaving. We are leaving- 


Researcher Mannava: We are leaving but staying. Parts 
of us are leaving. 


Technician Gryboski: Venus. 
Manu Thirteen: Repeat please, Leon? 


Technician Gryboski: Venus. It's Venus. Distance is 
stretching out to Venus and now it's snapping back. 


Researcher Mannava: Yes. | feel like it's now, the 
present time. Here in the room, | mean. 


Manu Thirteen: What are your most dominant 
impressions at this instant? 


Technician Gryboski: Relief. 
Researcher Mannava: Grief. 
Technician Gryboski: Yes. Yes that's right too. 


Technician Ishii: Diminishment. We have stepped away 
from the threshold. We have chosen to be lesser. 


Manu Thirteen: Anjali? 


Researcher Mannava: Yes. All of it. | long to see the 
machinery of the future. | am afraid of the grave that it 
lies in. | don't want to be sealed up to die, but I'm left 
behind. [STIFLED SOBS] God, it's making me cry. 


Manu Thirteen: Technicians? 


[TECHNICAN ISHII AND TECHNICIAN GRYBOSKI 
NOD ASSENT] 


Manu Thirteen: That's enough now. 
Manu Thirteen: Time since last dosage of therapeutic 
drugs is now five hours, thirty-eight minutes. Are you 


certain you want to proceed, Jacob? 


Researcher Fenton: ...yes. I've seen it. | saw it before, 
but | didn't know what it was. But I'm really seeing it now. 


You need to take this stuff into the record. 
Manu Thirteen: This is obviously distressing you. 


Researcher Fenton: Doesn't matter. We need to do this 
now, while it's still fresh. Then give me my cups full of 
pills again. 


Manu Thirteen: You said you've seen "it." What have 
you seen? 


Researcher Fenton: The skip! I've been inside it! 


Manu Thirteen: Security records have you accounted 
for in the facility for the entire duration of- 


Researcher Fenton: No! No not like that. These things, 
they travel. Not to places. Not like that. Then you think, 

and then they have you. Just like that! They're not here, 
not yet. But you can still go with them a little. They leak 

out, around what should be. 


Manu Thirteen: | don't understand, Jacob. Tell me about 
the location TRANSCRIPT ALTERED FOR READER 
PROTECTION 


Researcher Fenton: What did Mannava call it when we 
saw it. A mandala, | think. Me, | thought it was a maze. 
Thing with a maze, though, is that the way in and the 
way out remain the same while you're in them. 


Manu Thirteen: So SCP-2474 changes physical 
structure? 


Researcher Fenton: No, you're still thinking like one of 
us! You have to think like them. But then you let them in. 
Oh man, you don't want to let them in. Never mind, don't 
think like them. 


Manu Thirteen: | don't follow. 


Researcher Fenton: There are people in there! I've 


seen them. Not just people, though. No. There's 
machines, great gleaming towers of metal with no 
purpose that we can figure. Chasms going deep into the 
ground, wires, lights. They have shit in there that can 
grind thoughts, Manu. | don't even think they're 
supposed to do that. Just a side effect. That kind of stuff 
happens when you force things into states of being that 
they don't belong in. You can tell from the interior. Steel 
hovering in gaseous form through the halls, electrical 
current made solid. Can you imagine being locked up in 
something like that? 


Manu Thirteen: There are people? How is that so?
