Testing subjects will encounter a 1967 Ford F-100 pickup truck with 
white paintjob (SCP-1855-1) upon reaching the 2 km point. 
SCP-1855-1 will be blocking the road. After one minute, 
SCP-1855-1 will begin leading those that encounter it down the 
remaining stretch, ending in Louisiana Highway 22. The entity, 
SCP-1855-1, seems to act as a pilot vehicle commonly used for 
aiding motorists through construction areas overlapping roads. If 
subjects pass SCP-1855-1, they will arrive in SCP-1855-2. 


Subjects entering the threshold of SCP-1855 any time after another 
subject enters the area have not been capable of contact with one 
another physically or by means available through current 
unclassified technology, suggesting each instance of SCP-1855 is 
unique to the time entered. Those observing subjects crossing the 
threshold perceive them temporarily travelling backwards (after 


crossing the threshold), freezing momentarily, and finally 
disappearing in a “wave” from back to front. 


SCP-1855-2 is an area identical to Louisiana Highway 22 and the 
area around it, continuing on for at least 300 km or indefinitely. The 
area or dimension is believed to be a replica of the known world, but 
has been found to host a number of irregularities outlined in 
Document 1855-A. Alien inhabitants, such as subjects entering 
SCP-1855-2, do not appear vulnerable to any irregularities or 
hazards that would otherwise be lethal to them. 


SCP-1855-2 can be exited by looping around the previous route and 
reentering SCP-1855.

Interview with SCP-1855-1: The SCP-1855-1 entity located in the 
vehicle is only partially visible through a heavily tinted window rolled 
up to eye level. 


SCP-1855-1: Just stay in your car, there's demolition 
work bein’ done up ahead. 


Agent Breen: We just have a few questions. 


SCP-1855-1: Make it quick then, you’re gonna hold up 
traffic goin’ out. 


Agent Breen: How long have you been working as a 
pilot driver on this road? 


SCP-1855-1: That’s a funny question. Not long. Woke up 
this morning, got in my truck, and headed to the site. You 
the police? | ain’t done nothing wrong. 


Agent Breen: Where does this road lead? 


SCP-1855-1: On to LA 22. | suggest you turn around 
though; this doesn’t go nowhere you’d want to go, at 
least not in a timely manner. It’s just houses and lots of 
empty land for about 10 mile in every direction. Lots of 
twisting roads and dead ends and private properties. | 
suggest you take the interstate. 


Agent Breen: | don’t see any actual work being done 
here. It’s just you, and what appears to be freshly paved 
road on to highway 22. 


SCP-1855-1: Listen bud, | just drive the pilot truck. If you 
want to know about the plans around here | suggest you 
head down to Baton Rouge and talk to the people in 
charge. 


Agent Breen: Please step out of the vehicle. 


SCP-1855-1: Aw, hell, | knew this was fishy. Listen, if 
you don’t show me no badge | ain’t steppin’ out of 
nothin’. 


Agent Breen produces an FBI identification badge. 
SCP-1855-1: Wooo, oh boy. Now I’m curious. 


SCP-1855-1 rolls up its window and the door to the truck 
opens. No entity is present within the vehicle. Objects 
found within the vehicle are: one pack containing six full- 
flavor cigarettes, a gallon of water, a book of matches, 
174 apparently unspent matches on the floor of the 
vehicle, a pack of playing cards, an unopened package 
of corn chips, and a candy bar wrapper.

SCP-1856: Corrosive Corpse 


Item #: SCP-1856 
Object Class: Euclid 


Special Containment Procedures: SCP-1856 is to be housed at 
Site- , where it was first discovered. On-site personnel are to be 
cycled out of rotation on a monthly basis, eligible to return after a 
period of 6 to 8 months pending medical examination. As of / /20 , 
only one researcher and two additional personnel are allowed in the 
room with SCP-1856 at any given time. The room is to be regularly 
renovated, with masonry repaired on a bi-monthly bi-weekly basis 
(Note: See Addendum 3.) Researchers and other long-term 
personnel assigned to SCP-1856 are required to wear Level C 
hazmat suits. 


Description: SCP-1856 is the body of a human female of European 
descent, aged about 20-30 years at time of death, showing no signs 
of decomposition, rigor mortis, or livor mortis. The cadaver was 
found with its hands, feet, and tongue removed, its teeth replaced 
with ivory dentures, and its eyes replaced with glass orbs fitted over 
with ocular prostheses. 


Forensic analyses estimate the cadaver to be approximately 
130-160 years old. The amputated ends of the body's limbs show 
signs of cauterization by heated steel, and further sculpting to allow 
for fitting of prostheses, indicating these amputations may have 
occurred pre-mortem. Examination of the mouth shows similar signs 
of pre-mortem modification, with the removal of the tongue and 
lower gum line. No prosthetic tongue was found amongst the 
remains. The ocular prostheses could not be safely removed without 
damaging the body. 


Before death, the body's cells began undergoing a process which 
prevented anaerobic organisms from breaking down body tissue. 
The cells then began to divide, providing sustenance for unknown 


aerobic organisms which began to escape from the body some time 
after death. Once exposed to oxygen, these aerobic organisms 
cause a corrosive effect on certain organic and inorganic 
compounds, as well as a concentrated neurodegenerative effect on 
living organisms, manifesting in the mid- and forebrain. 


The cadaver was discovered in , New York, behind a walled-off 
section of a shoe store basement. The owner of the store, Joseph 
claimed to be unaware of the walled-off section until the cement 
lining around the concrete began crumbling, and the wall itself gave 
way under pressure. It was determined that the condition of the 
basement was steadily deteriorating due to decalcification and 
bacterial corrosion, putting much of the south-eastern portion of the 
building at risk of collapse. The Foundation acquired the property 
and Mr. was administered Class-C amnestics and financially 
compensated. Items recovered are logged at end of file. 


Agents and were the first on-site to oversee transfer of the 
building to Foundation control. The agents discovered the cadaver 
to be firmly ensconced in a depression in the soil, bottom-first. 
Attempts at retrieval were abandoned due to risk of damaging the 
body. Agent expressed revulsion towards the body, claiming that 
touching it "made my skin tingle, like bugs were crawling into my 
skin." 


Over a period of two years, personnel assigned to the site, including 
Agents and __ , began to develop symptoms of neurodegenerative 
disease, including Alzheimer's, Parkinson's, prosopagnosia ("face 
blindness"), Capgras syndrome, and Huntington's disease. Varying 
degrees of stupefaction were also recorded, consistent with 
catatonic-type schizophrenia. Two researchers began to exhibit 
signs of paranoia and delusions consistent with Capgras syndrome, 
believing that several guards and Agents assigned to the site had 
been "replaced" by imposters. The two were later found comatose 
while en route to Site- , and subsequently expired. Autopsies on the 
two confirmed severe physical damage to the brains consistent with 
toxic as well as traumatic encephalopathy. 


Within that period of time, % of personnel assigned to the site had 
died, with an additional % forced to retire due to disability. All of 
those unaffected were found to have spent less than one month on- 


site, with medical examinations revealing no signs of brain damage. 
Containment procedures were adjusted based upon the schedules 
of the unaffected personnel. 


Addendum 1: Testing of Site- and investigation of the surrounding 
area revealed the number of reported cases of neurodegenerative 
diseases began to spike considerably from the time of the object's 
discovery. The increase in civilian deaths linked to neurological 
illness caught the attention of local news stations and necessitated 
action on the part of Foundation front organization [REDACTED]. ? 
km of was partitioned and placed under quarantine, under the 
pretense of [REDACTED]. 


Addendum 2: Frequent renovation of the room containing 
SCP-1856 has proven largely successful in containing the release 
and reproduction of these aerobic organisms. Introduction of hazmat 
suits have proven successful in allowing personnel to remain on-site 
for extended periods of time. Reports of neurodegenerative 
diseases in the region have begun to drop off, as the number of new 
cases stabilizes and the affected persons die off. Pending further 
information, quarantine is to be lifted on [REDACTED]. 


Addendum 3: Frequency of room renovation and repair has been 
increased to bi-weekly, now necessitating two individuals qualified to 
handle masonry repair. Rate of decay has been increasing, though 
at a markedly depreciated rate. At current rate, it is estimated that 
SCP-1856 must be relocated within the next 5-6 years to avoid 
another potential outbreak. In the mean time, lifting of quarantine is 
authorized on [REDACTED]. 


Recovered Materials: 
Note: Items recovered below show greatly inhibited signs of 
corrosion. 


* One (1) prosthetic hand, found to fit SCP-1856, and with 
unusually sophisticated features. Found several feet away 
from the body. 


* One (1) hardcover book of full of handwritten passages. 
Pages contain coherent paragraphs, but have no unifying 
theme or story overall. Information logged appeared to be 


casual observations, daily recaps, or reminders, often 
repeated with different structures (Example: "It was a sunny 
day and the children were going to the park"/"It was sunny 
that day so the children were off to the park"). Final page 
contains a written message to an unknown person. 


Three (3) tea cups made of bone china. 


One (1) photograph, held underneath the prosthetic hand. 
Photograph is a badly worn daguerreotype depicting three 
young women dressed in clothing appropriate to the 19th 
century. Woman on the extreme right bears strong 
resemblance to SCP-1856. What may or may not be a hand 
prosthesis is visible on the woman, though this could be a 
mark caused by creasing.

Zhen Meii, | forgive you for not telling me. You

SCP-1857: Cultist Skull 


Item #: SCP-1857 
Object Class: Euclid 


Special Containment Procedures: SCP-1857 is stored ina 
dedicated, hermetically sealed containment chamber. Surveillance 
of SCP-1857 may be performed only through indirect means, and all 
personnel involved in the containment or research of SCP-1857 
must undergo mandatory weekly psychiatric evaluations. Personnel 
found to have been affected by SCP-1857 are to be quarantined 
under standard memetic hazard isolation procedures and 
administered a Class A amnestic. 


Description: SCP-1857 is a deformed human skull with what 
appears to be horns extending from its forehead. The letters "CM 
XIII" are engraved in a serif font on its back, and a Universal Serial 
Bus (USB) port is located at the base. X-ray photography has shown 
no wiring attached to this port, nor the presence of any other metallic 
components. 


When directly observed, subjects report seeing writing in blood in 
the language they are most familiar and/or comfortable with, though 
indirect observation via photography or closed circuit video does not 
corroborate this. Subjects report that the writing on SCP-1857 most 
often takes the form of insults directed at the reader, though the 
exact wording is often laden with spelling and grammar errors. This 
text reportedly changes when unobserved, often in such a way as to 
suggest that SCP-1857 was aware of its surroundings. 


Subjects exposed to SCP-1857 for extended periods of time often 
exhibit increased aggression and anger and a small number of 
subjects, particularly those of [REDACTED] ancestry, are prone to 
entering a comatose state when exposed to SCP-1857 for periods 
exceeding fifteen (15) minutes. Furthermore, affected subjects also 
exhibit increased levels of interest in mythical supernatural entities 


and the occult that increases with time. 


When SCP-1857 is connected via USB cable to a personal 
computer running a Windows operating system, a removable 
storage device will load and a software program contained on that 
device is automatically run. File system analysis of the device shows 
a capacity of 0 bytes, despite the presence of two files, "autorun. inf" 
and "cm13.exe" (both of which report as 0 bytes in size as well).
