Special Containment Procedures: Containment area is to be kept 
behind two reverse-pressure airlocks. Chemical shower sterilization, 
full contained-atmosphere haz-mat suits, and 24-hour post- 
interaction quarantine and testing are mandatory for all personnel 
entering containment area. Should containment be breached, the 
blast door for the containment and research area will seal, and 
chemical agent ZEER-217-11 will be pumped into the air. 


Any humans exposed to SCP-217 are to be contained and held for 
observation. Any items touched by those affected by SCP-217 must 
be sterilized. 


Description: SCP-217 is a virus, incurable by current means, with a 
rate of infectivity at 100%. It affects all organisms in the kingdom 
Animalia, and can be spread via touch or contact with bodily fluid. 
SCP-217 is very hardy, and can survive for years outside the host 
body. The progress of the infection is very slow, with some subjects 
going several years before manifesting any symptoms. 


SCP-217 alters the biochemistry of organic tissue, causing organic 
matter to re-arrange into a form of “organic metal’. The processes 
involved with this change are not yet fully understood, but the 
advanced stages are well documented. A subject will begin to turn 
into a complex arrangement of gears and clockwork, these taking 
over for the former biological functions. Advanced-stage infection is 
reported to be very painful, but earlier stages are oftentimes 
unnoticed, with only vague feelings of confusion, insomnia, and joint 
stiffness. Hearts are replaced by gears and small tubes, joints by 
gear networks, eyes by structures not unlike primitive “hand-crank” 
film cameras, etc. 


SCP-217 shows first on the outside of the body in all creatures 
except mammals. In mammals, it first converts the internal structure 
before manifesting outside the body. This can cause those infected 
to go for very long periods of time without knowing of infection. 
SCP-217 has even been shown to totally convert the inside of the 
body before showing any externally-visible symptoms. SCP-217 has 
infected several major metropolitan areas in the past, most notably 


The mental state of those in middle to advanced stages of infection 
has been shown to be much diminished. Subjects respond in a 
repetitive fashion, are very dull and mechanical in action, are easily 
distracted and confused, and appear generally irritable when faced 
with new problems. In addition, research on a fully “converted” brain 
has [DATA EXPUNGED] 


Document #217-6: Notes on symptoms 


Subjects infected by SCP-217 have, at early stages, reported no 
major symptoms, aside from increased lethargy, and a general lack 
of emotional response. Some have reported a feeling of “fluttering” 
or “moving” under the skin, coupled with a persistent “ticking” noise. 
This noise seems most prominent when SCP-217 infects the 
shoulders, neck, and head; however, it is inaudible if recording 
equipment is pressed against an affected area. 


Initial infection of SCP-217 is, as has been already stated, almost 
undetectable. As the infection advances, subjects will begin to feel 
sharp, “tearing” pain in areas that are being “converted”. It has been 
compared to a knife wound or a deep muscle tear, and can persist 
for hours, or several days, depending on both the subject and the 
area affected. The new clockwork organs appear to tear and rip at 
tissue for a short time, before becoming fully integrated and settling 
into the surrounding tissue, and this is believed to account for the 
pain. 


Areas infected appear to be metal, mainly brass, steel, and iron. 
Other substances have been reported, appearing to be leather, 
rubber, glass, wood, and other basic materials. Despite 
appearances, it is purely organic material, and even carries a 


subject’s DNA. Organs and tissues affected appear more resilient 
than normal, carrying the same strength and density as the 
materials they resemble, instead of normal tissue density. Areas 
damaged repair over time, but is much slower than standard human 
regeneration. 


Damaged areas can be instantly “repaired” by replacing damaged 
areas with new parts of the same type. Testing has shown that there 
are no ill effects if parts made from normal materials (steel, wood, 
leather) replace the existing bio-mechanical clockworks. 


Most alarming, people infected with SCP-217 can continue for 
months, even years, without being detected. With infection so easy 
to spread, hundreds could be affected before proper containment 
could be enforced. Infection appears to spread most quickly in large 
offices, malls, and other large concentrations of people. 


Note: Anything or anyone suspected or confirmed to be infected with 
SCP-217 is NOT to be allowed near SCP-882. 


Addendum: At this time, cross-experimentation between SCP-229 
and SCP-217 is allowed only with O5 approval.

SCP-218: Lamprey-Mass Organism 


Item #: SCP-218 
Object Class: Euclid 


Special Containment Procedures: SCP-218 is contained within a 
standard aquatic specimen tank (saltwater). Tank maintenance is to 
be carried out by remote drone only. No further procedures are 
required. 


Description: SCP-218 is a predatory colonial organism weighing 
approximately 1800 kg, consisting of several hundred parasitic 
lampreys of the family Petromyzontidae, designated Petromyzon 
anomalis. Individual Petromyzon anomalis specimens average 
between 50 and 90 cm in length, and are similar in appearance to 
the common sea lamprey, (Petromyzon marinus) with the primary 
exception of complex ultraviolet-spectrum skin patterning. Individual 
lampreys can break off from the primary mass and move under their 
own power, acting similar to non-anomalous specimens. These 
motile units will remain in the vicinity of SCP-218’s primary body, 
until captured and eaten by colony members. The central mass of 
SCP-218 contains the organism's primary organs, as well as a 
muscular foot for locomotion. SCP-218 is capable of surviving out of 
water for up to an hour, though it is greatly inhibited in mobility. 


Motile units of SCP-218 produce a paralyzing toxin, applied by bite 
or through the lamprey’s mucus sheath. This toxin inhibits locomotor 
muscles and will numb the target to pain — all other internal and 
mental processes will continue unaffected. The paralyzing effect has 
not been observed to dissipate, and no effective counteragent has 
yet been discovered. 


Early observation led researchers to believe that SCP-218 
reproduced through the parasitic implantation of motile units into a 
host body — this behavior has since been determined to be atypical 
feeding behavior, where numerous motile units will burrow within the 


body of still-living prey for upwards of 48 hours before normal 
consumption resumes. 


Addendum-01: Physical examination of SCP-218 shortly after 
containment revealed that the primary mass contained several 
foreign objects preserved within the main body cavity. SCP-218 was 
removed from its containment tank and tranquilized to allow for 
surgery. 


Objects removed from SCP-218 include: 


¢ 33 pearls, averaging 3cm in diameter. Holes bored through 
each indicate that they were previously part of a necklace. 

¢ 1 dolphin figurine carved out of smoothed coral. 

¢ 2 gold bracelets 

¢ 4 bone hair pins 

* 1 tortoiseshell hair comb 

* 1 bone figurine of SCP-218. Shows signs of heavy wear 
through handling. 

¢ 1 human skeleton, being that of a female child estimated to be 

between 4 and 6 years of age. Skeleton was similar to chalk in 

consistency, and embedded with 135 pearls. 

Scapula (believed to be that of a red deer) — engraved with 

three humanoid figures, two adults and one child. Presumed 

to be the subject and parents. 


Both the skeleton and artifacts date to approximately 7500 BCE, 
though do not resemble the artifacts of other Neolithic groups in the 
region of recovery. 


Addendum-02: SCP-218's behavior became significantly more 
agitated after removal of the aforementioned objects: entity would 
repeatedly beat against the walls of its tank or attempt to scale 
them. 


When one of the hair pins was placed back in the containment tank, 
SCP-218 used one of its colony members as a manipulator to 
retrieve the pin, and then place it back inside its central cavity 
through means of a large sphincter. This dorsal sphincter was not 
present until the removal of the body and artifacts.

SCP-219: Resonance Engine 


Item #: SCP-219 
Object Class: Safe 


Special Containment Procedures: When not in use, SCP-219 is to 
be kept in a dismantled state. All of SCP-219's parts, as well as 
replacements for those parts, will be stored in the Engineering 
Division warehouse on the grounds of Site-43. SCP-219 is not to be 
tested within twenty-four (24) kilometers of any Foundation facility 
that houses Euclid or Keter-class objects. 


Description: SCP-219 is a mechanical device consisting primarily 
of an array of pistons, driven by an electric motor which can be 
powered by attaching it to a separate generator. The entire machine 
is supported by a thorium alloy frame. The outer frame of each of 
SCP-219's pistons are also made primarily of the same thorium 
alloy. Attached to the outside of SCP-219 is an IBM Desktop PC, 
keyboard, and monitor, all shielded with shock-absorbent foam to 
prevent damage to them by SCP-219's vibrations. 


When SCP-219's computer is turned on, it automatically runs an 
"Earthquake Generator" program. Using the keyboard, a user can 
select up to twenty items from a list of commonly used construction 
materials, including multiple varieties of stone, soil, bricks, concrete, 
steel, iron, [DATA EXPUNGED] and glass. Selecting the "Other" 
option from the bottom of this list brings users to a different screen, 
enabling them to select other substances, including several types of 
wood, plastics, papers, and bone. A user may also choose to 
describe the properties of a material that is not currently on the list, 
name it, and save it to the list for future use. After selecting a given 
material, the user is asked to estimate the objects' mass, volume, 
and select a general shape to describe it. It is not possible to key in 
the composition of SCP-219 into SCP-219; any attempt to do so 
results in the computer displaying an error message and shutting 
down. 


After materials have been selected, the user is asked to specify a 
range of effect, from fifty (50) feet (distances are given in English 
units) to ( ) miles, and set two timers: one to determine how 
long SCP-219 will wait before activating once the program starts 
running, and one to determine how long it will run after it has 
activated. When all criteria have been filled in, the user may select 
"Run" to start SCP-219 or "Start Over" to enter a different set of 
criteria. SCP-219 cannot be shut down once a program begins 
running without being dismantled or damaged. 


When activated, SCP-219's pistons oscillate and begin creating 
vibrations in the air to match the resonant frequency of the materials 
selected by the user. Different sets of pistons create distinct 
resonances. These materials begin to vibrate in turn as they are 
struck by air waves, eventually shattering or otherwise coming apart 
from the strain put on them by the oscillations. The waves created 
by each oscillator do not seem to have any effect on each other 
even when they are traveling through the same media, enabling 
SCP-219 to resonate with many materials simultaneously. Studies of 
how this is possible, or how the effect might be duplicated, have 
been inconclusive. 


SCP-219 was recovered in , California, after an incident in 
which a heavy earthquake hit a city suburb without any prior warning 
from seismic geologists. Eye-witness reports gathered from 
survivors indicated the seismic disturbance had effects similar to 
that of a quake registering at 8.8 on the Richter scale, over a space 
of only 20 kilometers. Examination of the surrounding area showed 
far more subtle structural damage than should be possible for a 
quake of any magnitude, and the bodies of multiple people who died 
of massive internal cranial trauma, including several cases where 
the entire skull had apparently exploded. Foundation Agents found 
SCP-219 in the rubble of a collapsed house, along with some 
packaging materials and spare parts. The house's previous owner 
was one , who was later found dead of a gunshot 
wound to the head in a hotel in Boulder, Colorado. 


Included with the remains of the packaging was a diagram of a large 
funnel-shaped object attached with a complex of tubes to SCP-219, 
and instructions for how this "Resonance Focuser" was intended to 


be used. Its intended purpose, according to these instructions, was 
to channel the resonance-waves generated by SCP-219 on a much 
more linear trajectory, increasing the range of the machine in a 
single direction by %. The instructions suggest several 
applications for this attachment, including a makeshift offensive 
"wave cannon," a tunnel-carving device, and a "Resonant 
Annihilator" function created by turning the Focuser downwards! 
and keying the composition of the Earth's core into SCP-219. The 
search for this missing attachment is still ongoing. 


Addendum: For those who wish to use SCP-219 for demolition 
purposes, note that SCP-219 will work most effectively if it is on 
level, solid ground. Also note that for buildings utilizing an internal 
metal frame for support, SCP-219 is better used to target the frame 
than the materials built around it. If SCP-219 is still running but the 
vibrations appear to have stopped, disconnect the power supply and 
check to see if the oscillators have ground away the surface 
underneath themselves; they may not work properly if the ground 
the machine is set on is also shaking. You may need to move 
SCP-219 to a more durable foundation to ensure that it works 
properly. Consult User Manual 219-01 for more information. -Dr. 
Chung 


Addendum: Despite the obvious similarities to Nikola Tesla’s 
earthquake machine (see SCP-_ - ), SCP-219 clearly must have 
been built atleast years after Tesla's [DATA EXPUNGED]. Given 
what we know about [DATA EXPUNGED] it is most likely that 
whoever built SCP-219 simply took Tesla's designs and expanded 
on them. -Dr. Chung

SCP-220: Two's Company 


Item #: SCP-220 
Object Class: Safe 


Special Containment Procedures: SCP-220 is housed in an empty 
condominium on property recently acquired by Research Sector-09. 
The subject believes the building to be occupied by other residents, 
and should be allowed to persist in this belief. 


A false bus stop has been installed near the building's entrance; this 
measure has proven sufficient in deterring SCP-220 from wandering 
outside the containment perimeter. SCP-220 exhibits trepidation 
when venturing beyond the building's lobby, most likely due to 
mobility challenges; the subject will sometimes remain seated at the 
bus stop for upwards of one hour, before returning indoors. 


SCP-220's room has been provided with a telephone connected to 
an automated recording service, ostensibly a courtesy of the 
residence; dietary, medical, and recreational needs are to be 
ascertained from these recordings and several live video feeds. New 
requests should be submitted to Dr. Hart for approval or denial. 


In light of Incident 220-P, only D-class subjects are approved for in- 
person contact with SCP-220 and should be immediately 
quarantined after testing, in accordance with Sector-09's Type 2 
Contagion Procedure. 


Description: SCP-220 is a multiracial, English-speaking human 
male, aged 76 years as of 5/15/12.
