Subject: Kong Mu Shen, formerly a police officer. 

Date: - - 

DOD: - - 

Location: Province, China 

Cause of death: Heart attack 

Description: Death occurred while SCP-460 was in the area. 
Subject attempted to apprehend a manifestation, which promptly 
revealed his true nature. Cardiac arrest as a result of stress 
followed. Subject manifested normally, and after initial confusion 


variation in 
the anomaly’s 
appearance 
does not alter 
its effect. 


+ Addendum C: Experiments SCP-3568-3[A-C] 
Experiment SCP-3568-3A - / /19 
Subject: D-3219 


Procedure: A general anaesthetic was 
administered to the subject fifteen (15) 
seconds after she was shown SCP-3568. 


Results: The subject lost consciousness two 
(2) seconds after receiving the anaesthetic. 
She lay motionless for a further twenty (20) 
seconds before beginning to spasm. Death 
from cranial rupturing occurred after another 
five (5) seconds. 


Experiment SCP-3568-3B - / /19 
Subject: D-44871 


Procedure: A general anaesthetic was 
administered to D-44863 five (5) seconds after 
he was shown SCP-3568. 


Results: D-44863 became unconscious three 
(3) seconds after receiving the sedative. 
Anaesthetist prevented the subject from 
regaining consciousness for a further two (2) 
hours as per the instructions of Dr . An 
interview was conducted shortly after the 
subject awoke. 


Interviewed: D-44863 


Interviewer: Researcher 
<Begin Log, / /19 > 
Researcher  :Howdo you feel? 


D-44863: Uh...like someone hit me with a 
fucking sledge hammer. The world's worst 
goddam hangover. 


Researcher =: Do you remember your 
name? 


D-44863: Yeah, Jesus, I'm not that messed 
up. [Pauses] You actually want me to say it, 
don't you? [Sighing] It's 


Researcher — : What else do you 
remember? 


D-44863: Were we doing an experiment? 
Yeah, pretty sure | was doing my lab rat 
routine again. Don't remember what was 
involved this time though. [Coughs] Could | get 
some water? 


Researcher _ : After we conclude the 
interview. Please try to remember, D-44863. 
Do you recall being given an envelope? 


D-44863: An envelope? Oh, shit, yeah! | do 
remember that. 


Researcher : And what was inside the 
envelope? 


D-44863: [Laughing] Another envelope! You 
guys are real fucking hilarious. Yeah...| 
remember thinking it was gonna be some kind 
of infinite loop thing. Me sitting there opening 
mail for days on end. 


Researcher : And was it? 
D-44863: [Frowning] No. 


Researcher : What was in the second 
envelope? 


D-44863: [Swallows] A picture. Shapes. 
Glowing under the UV lamp. It's funny, | 
remember looking at those little shapes and 
getting this feeling like...like...Doc, | don't feel 
so good. 


Researcher — : What feeling did you get 
when you looked at the picture, D-44863? 


D-44863: Seriously. Argh, shit, my head! 
[Clutching temples] Jesus, feels like it's gonna 
explode! 


D-44863: [Ten seconds later] Foxfire...setting 
the nighttime woods aglow. [Pause] Three. 
Six. Four. Point. Two.

Experiment SCP-3568-3C - / /19 
Subject: D-11293 


Procedure: General anaesthetic was 
administered after five (5) seconds of the 
subject being exposed to SCP-3568. Once 
unconscious, subject was injected with a class 
B amnestic. 


Results: Subject regained consciousness 
after two (2) hours and was unable to recall 
SCP-3568, even after prompting. Subject 
made full recovery. 


+ Addendum D: Discussion of Numbers [Restricted] 


As well as the numbers spoken aloud by many subjects 
(see Addendum A), each has acquired a twelve (12) digit 
number at the nape of their neck immediately post- 
mortem. The latter number is different to the vocalised 
one in each case, and varies by subject. Physically, it is 
approximately two (2) inches wide by half an inch high 
and is composed of slightly-raised scar tissue that forms 
rapidly following the subject's expiration. A selection of 
the numbers encountered follows: 


Subject Vocalised Imprinted 
Number Number 
D-44863 506.1 113,146,559, 102 
D-37883 614.8 112,184,279,572 
D-44871 364.2 114,484,679,338 
D-42309 712.8 111,948,479,045 


When these numbers are plotted on a scatter graph (see 
Figure 2), they exhibit a strong negative correlation. The 
small amount of data we have means that, though 
unlikely, this could be coincidental. A request has been 
made for more test subjects. Request denied - we don't 
have limitless D-class personnel to throw at your pet 
project - O5-

<Begin Log, / /19 > 


Researcher — : | found something | think 
you'll find interesting, 


Dr : Good. Tell me what I'm missing. 


Researcher =: So plotting the two numbers 
against each other doesn't tell us much, right? 


Dr : Right, other than they appear to be 
somehow related to each other. 


Researcher _ : Sure, but it doesn't tell us 
what either number actually means. What if | 
told you the scar number is inversely 
proportional to the subject's age? 


Dr : I'd say what on Earth made you 
consider their age? 


Researcher _ : Call it divine inspiration. 
Think about what this means for a second 
though. The older a subject is, in other words 
the earlier she was born, the smaller the scar 
number is. 


Dr : That /s interesting. So...how old would 
you have to be to have nothing but a one on 
your neck? 


Researcher _ : That's just it! We're looking at 
numbers in the low hundreds of billions, right? 


Dr : Right. A hundred and twelve billion or 
so. 


Researcher _ : Well, it just so happens that's 
almost exactly our current best guess for the 
number of people ever to have lived. 


Dr : As many as that? Don't they say there 
are more people alive now than have ever 
lived in total? 


Researcher : That's a common 
misconception. Even if we're just counting 


homo sapiens, that's two hundred thousand 
years of history. For an awful lot of that time 
birth rates were decidedly high and life 
expectancy was almost comically low. We're 
talking lucky-to-reach-fifteen. An awfully large 
number of people lived and died in relatively 
short periods of time. So yes, it comes to 
around a hundred and twelve billion and, 
would you believe it, the numbers burned on 
our subjects’ necks are in that ball park. If I'm 
right about this, every person that's ever lived 
on Earth had one of those numbers. __, | think 
the scar number is some kind of...index...or 
serial number. And everyone's got one. 


Dr : The implications of that... 
Researcher — :| know. 
Dr : [After a moment] When's this index 


assigned though? At birth? Inception? 


Researcher — : Hard to tell from the limited 
data we have. I'd love to get identical twins in 
here, though. They ought to have adjacent 
indices...maybe even the same index, 
depending on when and how it materialises. 


Dr : You're right. So many avenues of 
study here. 


Researcher : Yeah...but there's more. 


Dr : You have been hard at work, haven't 
you? Go on. 


Researcher _ : The other number, the one 
they say right before they pop. That one's 
directly proportional to their age. 


Dr : Okay. What does that tell us? 


Researcher _ : The interesting thing is how 
it's proportional. The gradient of the line comes 
out at 14.5. 


Dr : So? What's 14.5? 


Researcher: Well...|'ll get to that. First, let's 
talk about the other things we've heard the Ds 
parrot. The stuff before all the numbers. 


Dr : Just a load of gibberish, isn't it? Side 
effect of a brain that's trying to leak out their 
ears. 


Researcher — :1 thought so too. One in 
particular caught my attention though. 
D-37883 talked about something - a creature - 
on his chest. | was sure that sounded familiar. 
When | looked into it | discovered a legend 
from Norse mythology about undead 
revenants shapeshifting into the forms of cats 
and suffocating sleeping people by sitting on 
their chests. 


Dr : I've heard of something similar to that. 
A creature that slowly crushes the life out of 
you as it gets heavier. Possibly an early 
explanation for sleep apnea. Something like an 
‘elf’. An ‘alp'? Don't think it was Norse folklore 
though - it was German or Dutch or something. 


Researcher _ : Yeah, similar ideas exist in 
other mythologies. In Norse legend it's called a 
‘draugr'. 


Dr : Alright, so why are we leaning towards 
Norse rather than German? 


Researcher _ : Let's look at some of the 
other experiments. D-44863 kept going on 
about it being "so blue". She just kept 


repeating that over and over. Guess what 
colour your average Norse draugr is? 


Dr : Blue's a strange colour for a cat to be. 


Researcher — :| agree, but we're talking 
about their human form. Draugr are 
reanimated corpses that sometimes shape- 
shift into cats. Cadavers often take on a pale 
blue-grey hue. Doesn't seem unreasonable for 
these creatures to be that colour. 


Dr : Fine. What else do we have? 


Researcher — : One subject muttered 
something about foxfire. Foxfire's- 


Doctor : [Cutting researcher off] 
Bioluminescent fungi in wood. Really beautiful 
in a dark forest, if a little eerie. 


Researcher — : What are you doing in the 
forest after dark? Don't answer that. The burial 
mound harbouring a draugr is said to glow with 
a blue-green light, like foxfire. It's a clear signal 
you should keep the hell away. 


Dr : Foxfire points to draugr too then. 
Getting harder to refute this, I'll admit. 
Anything else? 


Researcher _ : Yes, actually. There's a 
Norse myth about a draugr known as Thorir 
Wooden-Leg in which a ghostly seal rises up 
through the floor of a house in a coastal 
village, despite the inhabitants’ attempts to 
force it back down with clubs and hammers. 
Sound familiar? 


Dr : You've looked at the experiment logs 
more recently than | have. | assume one of our 


subjects alluded to something like this? 


Researcher: Pretty unambiguously. 
"Floorboards should stop them. But they keep 
coming!" 


Dr : Alright, alright. So they're all reeling off 
snippets of Norse folklore about draugr. 
You've convinced me. What's that got to do 
with this 14.5 figure then? 


Researcher — : Ahyes, from the graph. 14.5 
just happens to be the exact number of orbits 
a particular exoplanet makes around its star in 
an Earth year. 


Dr : Oh? Which exoplanet? 


Researcher — : That would be PSR 
B1257+12 b. More commonly known as 
‘Draugr’. 


Dr : [Sitting back in his chair] That's... 
interesting, to put it mildly. But what does it 
mean? 


Researcher _ : Well, it means the Ds are 

dutifully reporting their Draugr age right before 
they go bang. It's evidently entirely automatic, 
like a diagnostic readout on a failing machine. 


Dr : Wait a minute, though. If we're 
assuming these...pre-expiration ramblings... 
along with the spoken numbers, are somehow 
referencing the planet Draugr, how does that 
fit with its discovery? Correct me if I'm wrong, 
but wasn't it only very recently found? So if we 
didn't even know this exoplanet existed, let 
alone have a name for it, there's no way 
anyone could be chirping things about Draugr. 
Even if our subjects somehow were aware of 


the planet before the rest of us, they couldn't 
possibly have known we'd one day give it that 
name. 


Researcher — : They couldn't possibly...but 
they did. All our experiments predate Draugr's 
discovery and yet a significant number of them 
resulted in subjects making direct references 
to Norse mythology, immediately prior to 
reeling off their age on a far-flung planet 
whose name would eventually link to the 
statement they just made. 


Dr : That makes no sense. 


Researcher _ : 1! know. And yet the 
evidence... 


Dr : The evidence confirms exactly what 
you're saying. Well, | suppose we can add this 
to the long, /ong list of inexplicable phenomena 
we've witnessed since enrolling with the 
Foundation. [Sighing] Alright, why Draugr? 
What's there? 


Researcher — : Not an awtul lot, to be frank. 
It's in a dead system some two thousand three 
hundred light years away along with two other 
planets, orbiting a rapidly spinning pulsar. 
Pretty inhospitable, by all accounts. The beam 
of radiation emitted from the collapsed star is 
enough to vaporise more or less anything. 


Dr : And yet, there must be something of 
interest there. Let's talk to the folks at NASA, 
see if they can't lend us a hand in probing a bit 
deeper.

proceeded to operate as a law enforcement officer until 
dematerialization. 


Subject: Alex Grahl, formerly a notorious serial killer. 
Date: - - 


DOD: - -_ [Note, death occurred seven years before 
manifestation.] 
Location: , Germany 


Cause of death: Shot to death 

Description: No resemblance to subject before death, resembled a 
twisted, disturbing interpretation of a norse troll. Manifested at place 
of death, a hotel where the subject had been gunned down by law 
enforcement. Subject proceeded to murder and partially cannibalize 
most of the hotel’s patronage and staff. Neutralized and 
dematerialized shortly after by Mu-13. First case of manifestation of 
a long dead subject. 


Subject: James Strather, formerly a noted spiritual medium 

Date: - - 

DOD: - - 

Location: , GA, USA 

Cause of death: [DATA EXPUNGED] 

Description: Subject appeared incredibly vindicated, with his 
immediate action after manifestation being to inform every single 
one of his critics of this fact. Dematerialized early, the first example 
of living beings able to influence manifested spirits on the physical 
plane. 


Subject: Spot, formerly a domesticated canine. 

Date: -- 

DOD: Unknown 

Location: , Ireland 

Cause of death: Unknown 

Description: Subject appeared to be a manifestation of a mixed 
breed dog of unverifiable heritage, wearing a small collar engraved 
with the name “Spot”. Upon contact with Mu-13, subject interacted 
playfully with several task force members. Subject followed Mu-13 
during the entirety of the session. Dematerialized normally, to the 
dismay of Mu-13, which had grown fond of its company.

CREDENTIALS ACCEPTED 


On / /20 , the Allen Telescope Array (ATA) received a 
signal lasting precisely 2.31 seconds from the PSR 
B1257+12 system in the constellation of Virgo. The 
signal, designated SCP-3568-DR, was practically 
indistinguishable from background microwave radiation 
and would not have been detected had the Foundation 
not been specifically searching for such transmissions. 
The frequency band was relatively narrow, in the range 
96.55-96.56GHz, but utilised no fewer than 400 
channels, allowing a significant quantity of data to be 
transferred. The content of the signal was encoded using 
a highly sophisticated format and has, to date, only been 
partially decoded using the Foundation's on-site 
supercomputing resources. 


Further identical transmissions have been regularly 
received at intervals of 252.6 days, or exactly ten (10) 
Draugr years. That the interval is so regular implies the 
sender is deliberately accounting for relativistic effects. 
Furthermore, it indicates Earth is the intended recipient, 
as other planetary systems, and even other planets 
within the Sol system, would necessarily experience 
differing intervals due to their relative motion with the 
signals’ origin. 


It should be noted that the signals now being received 
have been propagating between PSR B1257+12 and Sol 
for 2300 years. Given this fact, and considering also the 
signals' uniform repetition, it is likely that similar 
transmissions have been going undetected for decades 
or even centuries.
