Dr. Sun: What is ten times eleven? 


D-016002: One-hundred-and-eleven. 


Dr. Sun: D-016002's responses have returned to normal 
speed. This suggests that it is possible for 150 nervous 
tissue to be swapped freely between host individuals 
without rejection. We will now begin the final procedure. 
D-016002, you will be given a full general anesthetic. 


(D-016002 is subjected to a general anesthetic, which 
takes several seconds to begin.) 


Dr. Sun: The patient is now under full anesthesia. Dr. 
Harlow, you may begin the process of tissue extraction. 
For this final procedure, we will be attempting to 
completely replace the brain tissue of D-016002 with that 
of D-13732. Previously, during the exploration of 
D-13732's cranial cavity, Dr. Harlow and | observed that 
the instances connecting his brain matter to his spinal 
matter were not secured in any way, and in fact seemed 
to be switching positions with other instances in the 
brain. We will be seeing how far this compatibility 
extends. 


(There is silence for the next hour as Drs. Harlow, Sun, 
and Robin remove the top of D-016002's skull and begin 
extracting her brain matter into a large glass container.) 


Dr. Sun: Extraction complete. D-016002's brain matter 
has been successfully removed. Dr. Harlow is now 
placing D-13732's brain matter into D-016002's exposed 
cranial cavity. 


(Silence for several minutes.) 


Dr. Robin: Heart rate steady. We have a pulse and 
breathing. Give it another minute... Alright. I'm going to 
wake her up. 


(There is a pause as Dr. Robin reduces the anesthesia 
and D-016002 awakens.) 


Dr. Sun: What is your name? 


D-016002: Michael [REDACTED]3. 

Dr. Harlow: (faintly heard in background) Jesus. 
Dr. Sun: Name something to sit in. 

D-016002: Beanbags. 

Dr. Sun: What is the color of grass? 

D-016002: Green. 

Dr. Sun: What is one plus one? 

(Quiet sloshing can be detected by the microphone.) 
Dr. Robin: Hey, uh, Sun — 

D-016002: Two. 

Dr. Robin: Sun, look. 


(D-016002's brain is shown to move of its own accord, 
subtly moving back and forth.) 


Dr. Harlow: Well... that's new. 
Dr. Sun: Do you feel any pain anywhere in your body? 


D-016002: My chest is kind of heavy. Feels just the 
same otherwise. 


Dr. Sun: Good to hear. Now, what is — 


D-016002: Hey, | usually feel pretty energetic, even 
before surgeries, but I'm kind of tired right now. Lately, 
I've been exercising before | sleep, but since | can't here, 
is it okay if | can just rest a little bit? 


Dr. Sun: Rest? 


D-016002: Like three, five minutes. | can do that here if 
it's okay. (A small portion of the top of D-016002's brain 


parts before making a gurgling sound. After the portion 
closes, sections of D-016002's brain retracts into itself 
rapidly. D-O16002's eyes close.) 


Dr. Sun: That doesn't seem good. (Dr. Robin steps away 
from the operation, making retching sounds as she 
leaves the room.) 


Dr. Harlow: D-016 - ah, D-13732, are you okay? 
D-016002: Yeah. (yawns) I'm fine, why do you ask?

SCP-151: The Painting 


Item #: SCP-151 
Object Class: Euclid 


Special Containment Procedures: SCP-151 should be kept in a 
locked storage compartment, covered by an opaque cloth. The keys 
to the compartment should be kept in the custody of the site 
commander when SCP-151 is not being researched. When research 
is being conducted, SCP-151 may be kept in a locked laboratory, 
provided it is always covered when not being used. 


Description: SCP-151 isa 1mx 1.3 m (3 ft x 4 ft) oil painting, 
apparently from the perspective of someone underwater. A subject 
who views the painting exhibits no initial effects. However, over a 
period of 24 hours, the subject's breathing becomes increasingly 
labored, culminating in the death of the subject. Autopsies reveal 
that subjects’ lungs have filled with seawater. Attempts to halt the 
drowning process by medical intervention have proven successful in 
prolonging the life of the subject, but have not stopped nor reversed 
the condition. 


The painting is not signed, but several names are written on the 
back. 


Addendum: SCP-151 was found in an antique shop in Ss 
after the Foundation began investigating a series of unexplained 
drowning deaths. As _ is landlocked, the Foundation dispatched a 
team of plainclothes agents after being informed of the nature of the 
water in the victims' lungs and that the victims had all been 
discovered on dry land. The agents discovered that the names 
written on the back belonged to a group of artistically inclined 
students, all of whom disappeared during a study abroad program in 

. Investigation into their fate is ongoing, and may provide clues 
as to the nature and origin of SCP-151.

SCP-152: Book of Endings 


Item #: SCP-152 
Object Class: Safe 


Special Containment Procedures: SCP-152 is to be kept ina 
locked chamber in Site-49, henceforth referred to as the "reading 
room". The reading room is off-limits to personnel below clearance 
level 2. The reading room will be equipped with one ceiling lamp, 
one security camera, one scanner-copier-printer (to be restocked 
with paper and ink as needed), one standard office chair, and one 
standard office desk upon which SCP-152 will rest. When not in use, 
SCP-152 is to be turned to its last page, so that any additions made 
to it can be immediately observed. A single guard will be posted 
outside of the reading room to deter unauthorized persons from 
entering the reading room. All personnel are advised to remain quiet 
if they are near the reading room. 


Description: SCP-152 is a large, hardbound book with leather 
bindings. The paper inside resembles vellum and is written upon in 
black ink. The contents of the book consist entirely of a series of 
entries that describe apocalyptic events, which are not always XK- 
class end-of-the-world scenarios but invariably deal with the 
extinction of humanity. The entries are arranged in chronological 
order, beginning with an unexplained spontaneous failure of the sun 
in 6000 BC and ending with other events close to the present day. 
Many of the entries describe apocalypses caused or facilitated by 
objects that are or were in Foundation custody, or are of a 
paranormal nature. There are also records of human extinction 
caused by more "conventional" means, such as nuclear warfare or 
deadly viral epidemics. Each entry describes in some detail the 
events leading up to the calamity itself, and the aftermath until the 
point at which the last human on Earth dies. 


It has been observed that the entries in SCP-152 change to 
whatever language the reader is most comfortable with, up to the 


point where the sentence structure can change significantly from 
reader to reader, or even begin using colloquialisms that only the 
reader would understand; only the basic meaning of the entries 
remains constant. If multiple people are looking at SCP-152, it will 
read in the personal language of whomever began reading first. If no 
one is directly observing SCP-152, it will display the language of 
whomever read it last. Rarely, words will appear in the book that do 
not "translate" and instead appear as horizontally arranged 
calligraphic characters which have not been matched to any known 
language. 


To the best knowledge of Foundation historians, most of the 
information contained in SCP-152 is accurate, diverging only at the 
point where the apocalypse occurs. In almost all cases, the 
difference is that a few key decisions were apparently made 
differently in SCP-152's version of history, leading ultimately to 
humankind's annihilation. 


SCP-152 resists all attempts to change or write in it. Inks, graphite, 
charcoal, and other marking materials do not adhere to the pages, 
and are easily brushed off. Lasers or other heat sources do not burn 
into the paper. Close inspection has revealed that foreign 
substances are stopped from actually coming into contact with the 
pages: at least five (5) micrometers of empty space are always 
present between the pages themselves and any foreign materials 
that might come into contact with them. For this reason, SCP-152 
does not decay, which also means that it has proven impossible to 
determine SCP-152's exact age. 


SCP-152 is self-updating, with newly-inked entries and new 
descriptions of how the last human died appearing at unpredictable 
intervals, always on the last page of the book; the date that a new 
entry appears corresponds with the date given in the entry for the 
death of the last member of the human species. When space 
becomes an issue, extra pages appear along with the text, and the 
spine of SCP-152 broadens accordingly. There have been 

updates to the book since it came into Foundation custody. As with 
past events, SCP-152 has proven to be up-to-date on current events 
until a point at which a catastrophe occurs. Because recent entries 
frequently concern entities or groups of interest to the Foundation, 


including the Foundation itself, SCP-152 is to be checked regularly 
for any information of importance. 


Addendum 1: With the acknowledgment made that letting this thing 
lie around where the public could find it is dangerous to us, is there 
any real reason to study it? Outdated hypothetical disaster scenarios 
aren't our concern; we've got plenty of real ones in the present to 
deal with. -O5- 


Addendum 2: The book is accurate enough about pre-disaster 
Earth that it makes a decent guide to the present. Plus, it gives a 
little perspective on the big picture of what some SCPs could do if 
they got loose. | think all researchers with clearance ought to read 
the last 50 pages or so just to drive home how important what they 
do here is. "For want of a nail," and all that. -Dr. Jansen 


Addendum 3: Jansen, half the entries in the last 50 pages show the 
Foundation screwing up and killing everybody. -O5- 


Addendum 4: Like | said, it gives a little perspective. -Dr. Jansen 


Incident Report 152-05: On the night of / /  , the security guard 
on camera duty noticed that SCP-152 was missing from the reading 
room. However, by the time she had finished reaching for the 
switchboard to report this, SCP-152 had reappeared, and there was 
a new entry on the last page. As this was the fifth such occurrence 
of sudden disappearance and reappearance (refer to Incident 
Reports 152-01 through 152-04), a simple test was conducted with a 
high-speed camera, a sensitive electronic scale upon which 
SCP-152 was placed, and an alarm set to go off if the weight upon 
the scale abruptly changed. The next three "updates" to SCP-152 all 
set the alarm off, and the high-speed camera revealed that SCP-152 
vanished from sight for exactly one (1) second each time. 


Addendum 5: / posit that the book isn't actually being "updated" as 
such... It's actually being replaced, and each time it changes we are 
actually receiving a new edition of it. | would very much like to find 
out where these are coming from. -Dr. Jansen

SCP-153: Drain Worms 


Item #: SCP-153 
Object Class: Euclid 


Special Containment Procedures: Specimens of SCP-153 are to 
be kept isolated in acid-resistant containers measuring no less than 
10 mx 10 mx 5M, partially filled with sewage and organic material, 
at Bio-Research Area-12. Every four hours, both the level of organic 
content and the structural integrity of each container must be 
checked. Under no circumstances are these containers to be 
connected to any internal or external plumbing system. 


Specimens of SCP-153 almost certainly still exist in the wild. Any 
reports of people mysteriously disappearing from showers and 
bathtubs must be investigated immediately. Agents must be 
equipped with infrared and ultraviolet sensors to circumvent 
SCP-153’s camouflage. Specimens should be brought alive to 
Area-12 if at all possible. 


Description: SCP-153 appears to be a species of nematode 
(roundworm) that canreach upto minlengthand cmin 
diameter. Specimens of SCP-153 live in sewers and drain pipes, 
and while specimens of SCP-153 can live off of most any organic 
material, they prefer to consume animal tissue. 


Specimens of SCP-153 excrete a highly acidic substance similar to 
[DATA EXPUNGED] from their mouths and gullets, and they have 
the ability to camouflage themselves both outside and in. SCP-153 
has developed a hunting technique where a specimen will swim up a 
shower or bathtub drain, dissolve the drain cover with its acidic 
saliva, and camouflage its gullet to look like a standard drain. Shortly 
after a human enters the shower or bathtub, the specimen [DATA 
EXPUNGED] back down the drain, leaving almost nothing behind. 
This entire process usually takes less than seconds. 


Addendum 153-01: Specimens of SCP-153 are to be kept isolated 
from each other except under controlled breeding conditions. —Dr. 
Kovalanskaya 


Addendum 153-02: Incidents in suggest that specimens of 
SCP-153 have started attacking people through sink drains, toilets, 
[DATA EXPUNGED]. Researchers are investigating how such an 
apparently simple animal can develop such relatively sophisticated 
hunting techniques. 


Addendum 153-03: Dr. Kovalanskaya has received approval to 
start a breeding research program with SCP-153, with emphasis on 
genetic engineering. The program [DATA EXPUNGED] as well as a 
potential method of organic waste disposal. 


Addendum 153-04: A controlled release of SCP-153 instances has 
been proposed as a potential containment method for stalling the 
spread of SCP-2717. Approval Pending.

SCP-154: Offensive Bracelets 


Item #: SCP-154 
Object Class: Euclid 


Special Containment Procedures: SCP-154 is to be kept within 
Weapon Locker 8, in Armed-Research Site-47. Personnel wishing to 
research or use item must submit the required request forms. 
Anyone attempting to remove the item without clearance, or from 
outside of the facility is to be terminated on sight. 


Description: SCP-154 is a pair of simple bronze bracelets, 
completely circular and large enough to comfortably hang off the 
arm of most people. Spectrograph analysis has proven that the item 
is composed entirely of copper (85%), tin (11%), arsenic (3%), and 
traces of other slight impurities (<1%). 


When both bracelets are worn on the same arm, and the wearer 
concentrates on them with arms extended in a depiction of a 
traditional "nocked bowstring" pose (achieved by having the arm 
with the bracelets completely extended in front of oneself, with the 
opposing arm extended up to the elbow of the fully extended arm), a 
large, indistinct, incorporeal bow will form in the extended hand, and 
both bracelets will glow lightly. 


From that point onwards, SCP-154 can be treated as a bow, until 
the pose or concentration is broken, which results in the bracelets 
reverting to normal. There is no actual bowstring, but completing the 
motion of pulling it achieves the same effect. 


When the "bowstring is pulled and released", the bones of the arm 
will be forcibly ejected from the extended limb, traveling in a straight 
path at speeds recorded over three hundred (300) meters per 
second. The missing bones and resulting damage to the arm are 
quickly regenerated, and the weapon is capable of being "fired" 
again within minutes. Tests using subjects possessing multiple 


arms/hands, such as SCP-1884-B1, have demonstrated the ability to 
fire SCP-154 several times, with the bones of different arms being 
used with each successive firing.
