 Item Number- SCP-100 Object Class- Euclid Special Containment Procedures- SCP-100 is to have six guards patrolling the interior of the perimeter's fencing, and two guards dedicated to the monitoring of the interior and exterior of both warehouses and the residential building, with rotations to occur every three hours. Any unauthorized personnel found within SCP-100 are to be detained for questioning prior to amnestic administration and release. Three guards are to remain within the storefront of SCP-100, with rotations to occur every eight hours. The storefront front entrance is to remain locked at all times, with keys provided to necessary personnel. Private property and no trespassing signs are to be posted on the front of the storefront to deter any drivers from stopping at SCP-100. Many constructs SCP-101 creates are to be removed from SCP-100 and melted down into slag, with the exception of SCP-102A and SCP-102B. Should SCP-101 become uncooperative, SCP-102A and SCP-102B may be removed from SCP-100 until the time that SCP-101 becomes cooperative again. The largest of the two warehouses within SCP-100 has been converted into a basic research facility. All objects created by SCP-101, excluding SCP-102A and SCP-102B, may be used for research purposes. Testing on SCP-101 itself may only be conducted with written permission from the Acting Head Researcher. Description SCP-100 is an abandoned scrapyard, 80 kilometers from F***ing, South Carolina, known as Jamaican Joe's Junkyard Jubilee. The scrapyard covers roughly 5,000 square meters of fenced off land, consisting of two warehouses, a storefront, and a small residential building, as well as neglected land and land used for storage. SCP-100 holds roughly 1,500 vehicles, both pressed and unpressed, as well as roughly 1,400 kilograms of separate scrap, estimated to be worth $5,000, or 3,870 euros. SCP-100's anomalous effect manifests through SCP-101 and its constructs, including SCP-102A and SCP-102B. Autonomy is lost when SCP-101 or one of its objects cross the fenced perimeter of SCP-100, remaining in this state until reintroduction. SCP-101 is an autonomous, sapient, humanoid construct consisting mostly of copper piping, uninsulated copper wiring, and aluminum cans. SCP-101 lacks the ability for written or verbal communication. However, it possesses the ability to communicate using rudimentary sign language. SCP-101 is largely uninterested in conversation outside of sales, and information gathered from it has been limited. SCP-101 appears to possess skill and craftsmanship, demonstrating the ability to operate tools such as arc welders, drills, and power saws, as well as heavy machinery such as car compressors and forklifts. SCP-101 possesses the ability to create autonomous constructs similar to itself, using material available within SCP-100. SCP-101 tends to create four specific animals, iguanas, crocodiles, turtles, and flamingos. However, SCP-101 has been known to craft other species, such as domestic pets. To maintain compliance, SCP-101 has been allowed to keep two objects, labeled SCP-102A and SCP-102B. SCP-102A and SCP-102B are constructs superficially resembling insects, assumed to be created by SCP-100, as they have occupied SCP-100 since the initial discovery of SCP-100. The names Ramon and Beatrice are welded into the backs of SCP-102A and SCP-102B, respectively. They appear to operate as both companions as well as guards for SCP-100, as they patrol the perimeter of SCP-100 except during intervals of interaction with SCP-101. SCP-101 appears to follow a ritualistic schedule, repeating the same actions daily. From 0800 to 1500 hours, SCP-101 enters the storefront of SCP-100, seating itself behind a counter and attempting to bargain with any humans within the storefront. Occasionally, SCP-101 will return to the yard prematurely for reasons unknown. From 1,500 to 1,600 hours, SCP-101 interacts with SCP-102A and SCP-102B, communicating using vague hand and arm gestures. Interaction tends to consist of grooming, repair, and activities resembling fetch and hide-and-seek. From 1,600 to 1,200 hours, SCP-101 performs various tasks, including taking stock of material within SCP-100, cleaning and maintaining tools and heavy machinery, and cleaning the interiors and exteriors of buildings present within SCP-100. From 2,200 hours to 0,100 hours, SCP-101 performs what is assumed to be leisurely acts, ranging from creating new constructs, interacting with SCP-102A and SCP-102B, and patrolling SCP-100. From 0,00 hours to 0,800, SCP-101 enters the residential building, where it remains seated at a desk for the duration of this time. In the event that a human enters the storefront of SCP-100 during the interval of time SCP-101 is seated behind the counter, SCP-101 will attempt to bargain with them, using a variety of gestures to convey meaning. Most attempts by SCP-101 are to sell scrap, figures of its own creation, or repair services. However, it has been known to purchase scrap. Despite SCP-101's inability to read, it possesses the ability to perform basic mathematics, as demonstrated by sales. Sales made by SCP-101 are typically met with some degree of unfairness. SCP-101 has been known to intentionally use faulty scales and contaminate scrap piles with cheaper metals, and has demonstrated knowledge of the area of effect within SCP-100, as SCP-101 has sold constructs repeatedly, despite the loss of autonomy when exiting SCP-100. Efforts to confront SCP-101 about this have been met with both distress and indifference, with referral to a sign posted on the wall reading, No refunds man, happening regardless of SCP-101's emotional response. SCP-101 was discovered on 110976, following reports of strange machines operating from within the scrap yard. These rumours were discredited as urban legends, and a Foundation agent was sent to SCP-100 to act as the landowner until containment was performed under the guise of property sale. The wooden privacy fence was built along the former perimeter of SCP-100, one-way windows were installed in the storefront, and a highway now running through the nearby town of... redirects the majority of civilian traffic. Addendum 100A Records show the property is owned by one Joseph DeVall, with the mailing address sharing the same name. Local utility companies report billing had stopped approximately three months before the discovery of SCP-100, which was found abandoned, save for SCP-101, SCP-102A, SCP-102B, and several avian and canine figures, presumed to be made by SCP-101. The initial sweep of the buildings revealed the residential building to be mostly bare, with the only sign of former occupants being a note found taped to the door of the storefront. Incident 100A On 060305, SCP-101 created a humanoid, autonomous construct, 10 cm in height, the first time SCP-101 has done so. Significant effort was put into this construct compared to others, with greater detail applied to the construct, including facial features, and JJ welded into the back of the construct, in stainless steel making up the majority of the construct. SCP-101 placed the construct on the counter of the storefront for the duration of the scheduled interval, both using vague gestures to seemingly communicate with one another. Following the confiscation of this construct, SCP-101 remained seated within the residential building of SCP-100 for a total of 10 days. SCP-100A The following is a copy of the note recovered upon discovery of SCP-100. Out to lunch, please see assistant. JJ Item Number SCP-118 Object Class Euclid Special Containment Procedures Due to the number and distribution of SCP-118, containment of every specimen is impossible. Zone SCP-118 red zones are to be closed off to all civilian marine vessels and divers, under the guise of a military presence or other plausible cover story. Contacts in navies known to operate near SCP-118 red zones are to be utilized in order to minimize the passage of military vessels through the red zones. If any area within the red zone has a depth of less than 1500 meters, the restriction is to be applied to aircraft as well. All human activity in surrounding yellow zones is to be monitored, and any non-military vessels or individuals approaching the red zone are to be turned away. In the red and yellow zones, protocol toxic harvest is to be followed to ensure the removal of devices generated by SCP-118. Furthermore, protocol cell watch is to be followed to ensure the early detection of any emerging red zones. Examples of SCP-118 can be stored using standard containment procedures for non-virulent anomalous microbes. Description SCP-118 is a species of ocean-dwelling protista that is capable of assembling functional, self-initiating nuclear devices from materials present in ocean water. While SCP-118 is unknown, and hence has not been classified by the scientific community, specimens resemble protists of the phylum Euglianophyta, but have significantly increased levels of movement speed, nutrient storage capability, and resistance to alpha radiation. Specimens of SCP-118 have been found in all of the world's oceans and seas. When in a survivable saltwater environment, specimens of SCP-118 will seek out materials including but not limited to iron, silver, copper, carbon, TNT, and uranium isotopes. When SCP-118 is located a material of interest, the material is absorbed into the cell using a method dependent on the size of the material. Single atoms and molecules, mostly substances that are dissolved in the water, are passed through the cellular membrane through specialized protein pumps. Larger particles smaller than the cell itself are ingested through phagocytosis. Larger pieces will have particles torn off through an unknown mechanism, which are then absorbed using the first two methods. This mining occurs even in solid and hard substances, such as metal ingots. Upon reaching a threshold of absorbed materials, specimens of SCP-118 will move towards an assembly area on the bottom of the body of water they are present in, and will contribute to the assembly of a nuclear device. The nuclear devices assembled are gun-type fission devices, using uranium-235 as their fissile material. Observation of devices in the process of being assembled show that the process starts with the assembly of a metallic rounded cylindrical casing for the device, followed by the creation of two subcritical masses of uranium and the conventional explosives to propel them into each other. The device is then finished with the assembly of a uranium-238 tamper, where the two uranium masses will collide, and the assembly of a trigger mechanism. SCP-118 appears to assemble the necessary components by adding miniscule amounts of material to an initially tiny material seed. Differing atoms and molecules can be added to the same component, and assembled components are not necessarily homogenous. It is currently unknown whether SCP-118 builds on the seed atom by atom, or by adding very small sub-micrometer fragments, the mechanism by which SCP-118 attaches new material to the seed seamlessly is unknown. The assembly time depends on the size of the device being assembled, water conditions, and mineral availability, but observations suggest that 300 days for a medium-sized device can be considered average. Once a nuclear device is finished, SCP-118 will detonate the device by completing a circuit in the trigger mechanism. Well, 90% of the nuclear explosions recorded as a result of SCP-118 have had yields in the 20 to 35 kilotons range, although yields as low as 4 kilotons and up to 1 kilotons have been reported. Aside from cases involving human interference, failure to detonate has never been observed, as all nuclear devices recorded have either been detonated of their own accord, or removed from the water prior to completion. Devices constructed by SCP-118 appear to be larger than man-made devices of similar design and yield, presumably due to the neutron-moderating effect of the water that separates the uranium masses throughout much of the device's construction. A given assembly area typically has between one and three devices in the process of assembly at any given time, although as many as six at a time has been observed. In zones where multiple devices are being simultaneously assembled, the devices are separated by enough distance to prevent the detonation of one from destroying or setting off the others. While the Foundation is unable to prevent civilians and other organizations from obtaining samples of SCP-118, its superficial similarity to existing species, few numbers, relative to all oceanic protista, lack of anomalous behavior outside material-rich bodies of water, and the Foundation's standard monitoring of scientific studies at risk of uncovering information about anomalous biological species ensures that the chance of SCP-118's true nature being determined through cell samples is minimal. There are currently six different active SCP-118 assembly areas known to the Foundation. While the natural disappearance of an assembly area has been observed, the current consensus among researchers assigned to SCP-118 is that elimination of assembly areas without massively noticeable effects is currently unfeasible. Thus, containment is to be established at SCP-118's assembly areas to be designated red zones and surrounding yellow zones. Furthermore, areas with elevated concentrations of SCP-118 zones of interest are to be monitored for signs of assembly areas. SCP-118 containment zones. Red zone lies within red city limits. This, combined with the shallow average depth of red zone, the heavy shipping traffic in the area, the ongoing tensions between a nuclear power and the presence of Foundation personnel and facilities in the city makes a nuclear detonation in this red zone unacceptable. In addition, heavy ship traffic through the area and heavy air traffic above the city make restricting access for any long period of time impractical. Addendum 118-1 Following the USS Red Incident, the exclusion radius used when drawing red zones had been increased. Containment protocol toxic harvest has been updated. Addendum 118-2 With the signing of the Partial Test Ban Treaty and growing number and capability of nuclear detonation detection methods in use, the consequences of nuclear detonations caused by SCP-118 have increased. Containment protocols have been revised in light of these facts. Addendum 118-3 Due to the significant cost of containing SCP-118 red zones, the O5 Council has requested trials on possible methods to eliminate SCP-118 assembly areas. Red zone eradication trials. Summary Introduction Researchers with access to the files on SCP-118 are allowed to submit proposals to eradicate an SCP-118 assembly area with acceptable levels of collateral damage. The ones approved by Toxic Harvest Command and the O5 Council will be carried out. Trials are to be performed in red zone. Proposal Steralization of unfinished nuclear device in immediate surroundings using a UV light emitter. Approval Approved Result Area around unfinished warhead initially free of microorganisms, however, SCP-118 concentration returned to normal levels within an hour. Unsustained sterilization of sites seems ineffectual. Any method we come up with will have to keep the red zone or at least the seafloor of it free of SCP-118 for an extended period of time. Dr. Brandt Proposal Sodium hypochloride pumped to ocean floor Approval Denied Result N.A. The chemicals will disperse too much to be effective. Any amount sufficient to reduce SCP-118's numbers will cause massive ecological damage. Dr. Klaus Proposal Depth charged bombardment of ocean floor to break up under assembly devices. Approval Denied Result N.A. Aside from the fact this would break our naval budget, the chances of triggering the conventional explosive in the devices and causing a fizzle is too high. It would also make our activities even more detectable with hydrophones. Dr. Klaus Proposal Sweeping of ocean using a cobalt-60-powered directional gamma ray emitter Approval Approved Result While procedure resulted in the sterilization of swept area, procedure was far too slow to sterilize entire red zone before specimens returned. Keeping entire red zone sterile would require impractical numbers of emitters and vessels. While it's a shame the device cannot get rid of the red zones for us, I think it can be of use to our device recovery teams. The gamma rays can sterilize the devices we recover to prevent undesired detonations during the recovery of almost complete devices. The gamma rays can also penetrate into areas where our current chemical and UV sterilization methods can't reach. Captain Thompson, RZ-3's own commander. Proposal A plastic membrane to block access to ocean floor at red zone Approval Proof of concept on one under-assembly warhead approved Result First attempt was unable to acquire a watertight seal around warhead. Membrane in second attempt was too fragile for ocean conditions and was torn off its moors. Third membrane, manufactured using a thicker and sturdier design, had hundreds of micro-tares ripped in it within hours, possibly due to SCP-118's mining action. Not surprising. Considering that SCP-118 has been known to wear through the casings of old artillery shells to harvest the explosives within, we had hoped that cutting off the assembly area would work better than cutting off the raw materials. Dr. Klaus Proposal Compound Pump to ocean floor Note Proposed by Dr. Former researcher for SCP-118 currently working at one of the Foundation's chemical research divisions. Tests confirm that compound is lethal to SCP-118, remains concentrated at bottom of water, and degrades into relatively harmless chemicals in water over a period of 15 hours. Approval Approved Result Over one week, SCP-118 concentrations on ocean floor fell to 3% of previous levels. No signs of progress observed on two known uncompleted nuclear devices in Red Zone. However, 100 days after the start of the experiment, an under-assembly nuclear device was detected 60 kilometers north of the Red Zone. Measurements in the area indicated vastly elevated levels of SCP-118, and the area around discovery was reclassified as a Red Zone. Furthermore, the unexpected breakdown of compound by certain species of oceanic bacteria resulted in toxic byproducts that caused a noticeable die-off of fish in treated zone. Upon stoppage of experiment, Red Zone was observed to gradually migrate back to former location. It seems that making a Red Zone non-viable served only to move SCP-118's assembly areas to a new location. Nevertheless, perhaps if we can improve compound or find a new one whose application is more subtle, we can move Red Zones into areas away from areas of human habitation or commercial activity. Dr. W. Proposal Use of SCP-118 Approval Denied Result N.A. SCP-118 is classified properties that preclude its use in such a manner. 055 Conclusion Due to increased media attention to areas around one of Red Zone, due to aftermath of the application of compound and the lack of proposals without high risks of substantial collateral damage, testing in said Red Zone has been suspended. Addendum 118-4 Our research has determined SCP-118 enriches uranium by exploiting the fact that U-235 has a slightly greater preference for a high oxidation state than U-238. SCP-118 specimens which have harvested large amounts of uranium and are near assembly areas appear to develop specialized organelles resembling a series of thousands of vacuole-like chambers with mitochondria-like organelles within them responsible for catalyzing reduction in oxidation reactions. In a given chamber, uranium is repeatedly reduced and oxidized. Compounds with uranium in higher oxidation states are transferred up the chain of chambers, while compounds with lower oxidation states are transferred down the chain. This results in a small amount of highly enriched uranium at the very end of the chain. Researchers and engineers at research sector have managed to create a prototype uranium enrichment device based on the principles employed by SCP-118. While the prototype was unable to produce weapons-grade uranium without using unreasonable amounts of time, it was successful in producing reactor-grade uranium, albeit at significantly greater cost than conventional methods. Despite its current limitations, the idea shows promise, and I have forwarded our findings to the relevant front companies. Item Number SCP-125 Object Class Euclid Special Containment Procedures Supports for instances of SCP-125 are kept in padded boxes and covered with a fine nylon mesh that allows vision through but obscures the surface of the mirror by at least 25%. These supports consist of a polished metallic surface, currently silver-plated brass, with no sharp or irregular edges, which must imperatively be smoothed out to prevent rips in the protective mesh. To further prevent incidents, any person penetrating the room where SCP-125 is located must also wear such a protective mesh over their face. Metal-plated glass mirrors should be avoided for the purpose of containment, as SCP-125 is capable of moving from the glass itself to the metal surface. Any metallic surface in the room must be dulled to prevent reflections. As an additional security measure, the room is kept in darkness and monitored only via infrared and ultraviolet lighting when no experiment is taking place. No mirror or comparably reflective surface, including but not limited to metal case pens, sunglasses, laptop computers, and glass objects may be allowed in the room outside controlled experiments. The SCP may not be photographed or filmed in its unrestrained state. If any personnel on site, and particularly personnel having recently been involved with SCP-125, reports seeing black dots, MTF-8-10 and CHI-7 will be immediately put on standby, and a level 2 alert for potential containment breach will be declared. Individuals contaminated will undergo containment protocol 125B, and may not return to active duty until the instance of SCP-125 affecting their cornea has been rendered completely inert. Description. SCP-125 is an apparently sentient being that can only exist within reflections. At rest and viewed up front, it takes the form of a black circle, 17.2mm in diameter, resting on the reflective surface. Its first anomalous characteristic is that it appears as a perfect circle to any observer. Regardless of the surface's angles, bends at the location of the viewer or viewers. In that regard, it acts more as if it were a sphere in contact with the surface, but lacking any shadow or highlight. And this, even where an obstacle such as containment mesh makes it clear, SCP-125 does not extend beyond the surface it has imprinted to. SCP-125 does not reflect visible light or infrared. When observed in ultraviolet however, data expunged, up to and including data expunged. For unclear reasons, it also emits a minute but measurable and constant amount of x-rays. SCP-125 is capable of movement across the surface it currently exists on. This movement may only occur across a surface uninterrupted by either an angle, the surface must follow a reasonably continuous curve, or a non-reflective area. SCP-125 has demonstrated incapability to cross scratches and frosted or etched areas of a surface. In many instances however, SCP-125 will circumvent these limits by jumping to a reflection to round a corner, or between the separate outer glass and silver surfaces of a metal glass mirror, hence the preference for opaque metallic surfaces for containment purposes. Although capable of moving anywhere along the surface, SCP-125 generally remains immobile in a location near its edges if any, and if on a surface that has a specific immobile orientation will usually remain in the lower right corner or its equivalent, even if the item is later moved. Any reflective surface capable of displaying a reasonably accurate reflection of SCP-125 can host it. So far, this has included a wide range of mirror quality surfaces, glasses, polished or varnished surfaces such as stone and wood, glossy plastic, and even undisturbed pools of liquid or polished nails. When reflected by another surface, SCP-125 is capable of instantly transferring to it. However, SCP-125 cannot survive on or transfer to or away from a surface smaller than its own area, approximately 2.32 square centimeters. Should it be constrained to one, it will rapidly become translucent and disappear completely. The entity has demonstrated a certain level of sentience and even sapience. Despite lacking physical existence, it appears unwilling to be touched directly or otherwise hidden from sight. It will also resist to the best of its abilities, any attempt at reducing its freedom of movement, either by jumping to another surface or moving across its current one very fast. It will also flee from perceived threats, even complex ones expressed by speech, demonstrating an understanding of human communication. How it is capable of this, and whether it can or wishes to communicate back, is currently unknown. In its normal state, SCP-125 is completely harmless and incapable of multiplying. It is, however, perfectly capable of moving to a living reflective surface, specifically that of a living animal's cornea. It will, in fact, do everything in its power to do so, indicative of a natural desire. Once it has achieved this, SCP-125 diminishes in size by a factor of 10 to 1.72 millimeters in diameter. While existing on the surface of a living tissue, SCP-125 becomes capable of multiplying and infecting a potentially unlimited number of surfaces, as opposed to merely moving between them. This multiplication occurs within the cornea, rapidly causing the victim to complain of seeing dots. Past this stage, the SCP-125 infestation will rapidly, within five to nine days of initial infection, crowd out the entire tissue, causing the eye to go blind. After which stage, the cells of the eye and optic nerve appear to undergo mass apoptosis, causing a non-infectious abscess. Why this occurs has yet to be elucidated. Only after the apoptotic stage has run its course, does SCP-125 cease being contagious. No treatment for a SCP-125 infestation is known to be efficient, beyond keeping the affected eyes tightly covered to prevent further spread and administration of heavy antibiotics to reduce risk of infection. Outbreaks continue to occur on an irregular basis, suggesting that SCP-125 is either a naturally occurring phenomenon or that it was spread over much of the planet at some point prior to the beginning of written history. Item number SCP-156 Object Class, Euclid. Special Containment Procedures SCP-156 is to be kept in refrigerated storage unit 19C, except when removed for experimentation. Subjects infected by SCP-156 are to be restrained and monitored for their own safety. From September 21st to March 21st, infected subjects should be kept within a secure storage unit, unless the experiment's parameters indicate otherwise. Both storage facilities should be monitored by security camera. The termination and autopsy of D-Class personnel assigned to SCP-156 should be delayed until after March 21st. No personnel are permitted to consume SCP-156, except D-Class personnel, unless approved by a Level 3 staff member. Description SCP-156 is a group of exactly 181 pomegranate aryls. The number of instances of SCP-156 is constant. When one is ingested or destroyed, it is replaced instantaneously with a new one, among the largest group of contiguous instances. Otherwise, the instances can be moved around freely. After leaving the group, i.e. after an instance is touching no other instance, the instance will spoil normally, after which a new instance will appear. When all instances are destroyed simultaneously, all 181 instances reappear randomly at the location of one of the destroyed aryls. Attempts to measure the time between destruction of one instance and the appearance of a new one using high-speed cameras have so far failed. If SCP-156 is ingested between March 21st and September 20th, subjects display no signs of infection until noon of September 21st, when all vital processes abruptly cease. A similar effect is observed immediately when SCP-156 is ingested after September 21st. Despite being technically dead, post-mortem examinations of subjects have been unable to discover a cause of death. Subjects appear to have been in perfect health, aside from any pre-existing conditions. While dead, subjects do not show any signs of decomposition, though the bodies of many subjects begin displaying bruising and scarring consistent with torture. While the majority of subjects suffer these wounds, not all do, and no reliable formula has been discovered to predict which subjects will be affected. Infected subjects remain in this dormant state until noon of March 21st, when life processes restart. Subjects remember little of the intervening time period. While most subjects are entirely unaware that any time has passed since their apparent death, some claim to recall a pale, white male face and a wilting pomegranate tree. Subjects continue to die and reanimate annually on September and March 21st respectively, until killed by another cause. Reanimation only occurs from deaths caused by ingesting SCP-156. After undergoing a single death reanimation cycle, subjects begin displaying high levels of distress and paranoia as time approaches September 21st, even if they have not been made aware of the death reanimation cycle. Furthermore, subjects will take extreme lengths to avoid taking any sort of risk or danger to their person, even if they had displayed risk-taking behaviors prior to ingesting SCP-156. Over the course of multiple death reanimation cycles, these psychological symptoms become more pronounced. At the same time, physical symptoms during the dormant period increase in intensity for the subjects suffering from them. Eventually, physical wounds on subjects will begin to emulate burns and puncture wounds. Many subjects gain a phobia of dogs and dead plants after 3-5 reanimations. After several deaths caused by SCP-156, the ocular tissue undergoes necrosis in many subjects. This tissue does not reanimate with the rest of the body. Often, after 10 or more reanimations, reanimation of bodily processes will occur, but the subject will fail to regain consciousness, entering a comatose state. Death and reanimation continues annually, even after subjects have reached this stage. SCP-156 came to the attention of the Foundation after an incident in Greece, after several people died on September 21, 19 without apparent cause. The Foundation became involved after locals reported the return of several of the dead, who had been interred in above-ground vaults the following spring. After questioning these subjects, all reported having attended a party at the house of one AK, who had been buried and was found asphyxiated in her coffin. SCP-156 was discovered within the house, fresh, despite the intervening six months since the incident. Testing commenced on D-Class personnel. D-E15624, the first test subject, died in September, and was autopsied. No cause of death could be found. Subject was left under monitoring and storage. In March of the same year, subject began to show brain activity, and subject's heart began beating, despite the body having taken significant damage during the autopsy. D-E15624 expired shortly thereafter, without regaining consciousness. Arrows given SCP status and longer-term testing was ordered. Item number SCP-165 Object Class Keter Special Containment Procedures Housed in a facility at Armed Biocontainment Area 14, SCP-165 is to be treated as a contagious pathological organism. The highest sterilization and quarantine procedures are to be followed. Microwave field generators around SCP-165's area are in place to restrict movement of its dune within its containment area. Once every nine days, SCP-165 is fed live cattle, weighing at least 750 kilograms. Description The organic component of SCP-165 resembles that of typical parasitic mites, 750 micrometers in length, with eight legs, and a genetic structure similar to the house dust mite. The main difference is the hermit crab-like behavior of attaching grains of sand to its back. It is unknown what purpose the sand serves, but the massive colony of SCP-165 numbers into hundreds of billions, to possibly trillions, creating a rather large dune. The similarities between data expunged and SCP-165 are only superficial. Data expunged's colony is protozoan in nature, and apparently shows a collective intelligence and awareness that is not understood. SCP-165's colony is made up of individual akari who don't show cooperation, but rather competition in the hunt for food. Like mosquitoes, they rely on chemical detection of carbon dioxide and sugars in the air to detect prey. The akari mites roll and bound over one another toward prey, only using their legs to climb over one another. When in contact with the flesh of animals, they release a numbing chemical toxin in their bite similar in makeup to that of mosquito and flea bite toxins. Subjects are typically unaware that millions of mites are taking turns at grabbing mouthfuls of its flesh as they swarm around their victim. A typical swarm resembles a swirling vortex around a victim or victim's appendage. The SCP-165 colony is efficient enough in their competitive swarming that most animals appendages can be defleshed and reduced to bone within minutes. The numbing toxin is so effective that sleeping victims may not wake up as their limbs are being eaten away. The akari mites are resistant to all but the most dangerous of pesticides. They retreat from heat and will often seek shade when available, being the most active during the night, hunting for large sleeping prey. Their vulnerability to heat is the most preferable technique for containment. Addendum Acquisition It is apparent that the US government has been aware of dunes of SCP-165 for some 80 years. The area where SCP-165 was found is a now forgotten German immigrant ghost town of Fredericksburg, Arizona, in the Tule Desert near the Goldwater Air Force bombing range. The remote town of Fredericksburg was founded sometime in the late 1800s, and by 1908 had become a ghost town. A passing cavalry troop reported that the inhabitants had disappeared and that the buildings were empty. They attempted to stay one night in the abandoned hotel, only to have seven of their horses reduced to piles of bone. All but four of the soldiers fled in the middle of the night, saying that sand was filling the building like a flood of water. Those four were never seen again. During the late 1950s, the US military attempted to exterminate SCP-165 by turning the area into a bombing range. It was successful in reducing the numbers of SCP-165, but in the late 1980s it became apparent that a ground cleanup and extraction was needed to remove the presence of SCP-165. Mobile Task Force Epsilon-9, aka Fire Eaters, were dispatched for containment and extraction of SCP-165. Upon entering the town of Fredericksburg, an upturned sign was found, reading, Beware the Creeping Hungry Sands. The flame accelerators of MTF Epsilon-9 proved highly successful in glassing the sand of SCP-165 and reducing its number to a manageable size. A living dune of nearly four metric tons of SCP-165 was contained and transported to ABC Area 14, where it is monitored and contained.
