Item #: SCP-1737
Object class: Safe
Special Containment Procedures: SCP-1737 is located underground, at the location designated as Site-██. It is to be kept within a metallic safe. A single mercury thermometer is located on top of the safe which measures the temperature inside. The safe should be kept closed.
SCP-1737's containment chamber may be cleaned once a year.
Note: due to sensitive research taking place at Site-██ and the instruments involved therein, maintenance personnel may only bring Foundation-approved cleaning tools and clothing with them when conducting maintenance.
Description: SCP-1737 is a horseshoe-shaped object appearing to undergo an exothermic reaction without a clear source. At the time of containment, the object also emitted gamma radiation, but this behaviour has not been seen to occur in some time. The object is usually █ degrees above room temperature.
While not much else is known about the object, it has been determined to be a low-priority research item, and is thus to be contained at Site-██ indefinitely until further notice.
Item #: SCP-7777
Object class: Keter
Special Containment Procedures: SCP-7777 is contained 777 meters underground at Site-77, built specifically to store this object. It is to be located inside an iron safe measuring 77 centimeters by 77 centimeters. If the temperature within the safe shifts either way from 77 degrees Fahrenheit, an automatic kill-switch mechanism will release the safe into a shaft 7777 meters deep. Recovery is not to be attempted.
Site-77 is to be kept vacated of any permanent personnel. Absolutely no measuring devices are to be brought to Site-77. Absolutely no measurements may be taken at Site-77.
Description: SCP-7777 is a currently 7cm x 7cm horseshoe-shaped object with reality-warping effects. Whenever any measurement is made of or around SCP-7777, it appears to distort reality in such a way that the instrument of measurement used will always show a number consisting only of sevens, on whatever scale it uses. The alteration appears to be whatever is closest to the current baseline — as such, if it is 5 degrees Centigrade around SCP-7777 and temperature is measured, it will be 7 degrees rather than 77. Its effective range is difficult to measure given the object's properties, but it is believed to be a sphere with a radius of 7km. Note: It is not yet known exactly what SCP-7777 considers to be a measurement device. As such, any document or paperwork that relates to SCP-7777 and contains numerical data should use sevens as its only number (hence the re-classification of this object as SCP-7777).
A temperature measurement in Fahrenheit was chosen in order to limit SCP-7777 to an easily containable form. 77 degrees Fahrenheit is close to room temperature, thus not requiring advanced containment devices to be used for it (and thus limiting the number of measurements needed to be made in order to install them).
Few experiments have been conducted on SCP-7777, as it has been deemed capable of causing an XK-Class event. Incidents preceding its re-classification as a Keter-class object are documented below.
Incident Log 7777
Background: Pairs of barometers, thermometers and hygrometers are brought to Area-77 (a testing site directly above Site-77). Each individual device in the pair uses a different measuring scale.
Results: A strong dust devil forms adjacent to the devices due to localized differences in temperature and air pressure, and stabilizes without causing much damage. Dr. ████ measures the windspeed, getting a readout of 77.7km/h.
Background: A weight scale is placed in the middle of Area-77. The weight scale uses the Imperial measuring system, giving a readout in pounds.
Results: A localized gravitational anomaly is observed to form directly over the weight scale, forcing it to show 7 lbs. Attempts to calibrate the scale fail; all calibrations result in the anomaly getting either stronger or weaker, such that the scale always reads 7 lbs.
Background: D-3451, weighing 67kg (148 lbs) is ordered to stand on the weight scale used from the previous experiment.
Results: The gravitational anomaly disappears. D-3451's legs and lower torso also disappear. The scale shows that subject now weighs 77lbs. Subject dies of blood loss soon thereafter.
Dr. ████'s Note: Why was D-3451 structurally altered while the scale only experienced a gravitational anomaly? I think I may have an idea…
Background: A small nuclear bomb with a yield of exactly 75 tons equivalent of TNT is detonated next to a specially constructed device to measure the bomb's yield. The device is rated for a 76t explosion. An explosion yielding 77t or higher will destroy the device.
Results: The bomb fizzles, resulting in a 7.77t explosion. Cause for the fizzle is unknown.
Dr. ████'s Note: As I suspected, SCP-7777 appears to avoid destroying or in any way changing the measuring device itself. But what did it do to the nuke?
Background: Dr. ████, wearing a hazardous materials exposure suit, attempts to uncover the reason behind the nuclear bomb's failure.
Results: Upon measuring weak atomic forces inside the physics package of the bomb, Dr. ████ is thrown back by an unidentified blast. A presence of gamma radiation (exact measurements were not taken for obvious reasons) showed that the blast was a very compact thermonuclear explosion. Dr. ████ is uninjured.
Dr. ████'s Note: This presents an interesting problem. Without the ability to measure anything in SCP-7777's area of effect, how are we supposed to know what it's actually doing? Perhaps it's best not to concentrate on cause and effect and just observe.
Background: A bottle of █████████ brand vodka is measured for alcohol content.
Results: Bottle contains 77% alcohol.
Background: D-0258 is told to drink from the bottle. Seven Foundation Agents have their firearms ready nearby. After showing signs of intoxication, D-0258 is told to count the number of Agents he sees.
Results: [DATA EXPUNGED]
Dr. ████'s Note: Requesting a Mobile Force to track down Agent ███'s escaped double.
Background: A thermal imaging camera taken from a steel mill is trained at D-0258. The camera measures in degrees Centigrade, but is not capable of measuring any temperature below 500 degrees Centigrade. The camera is set to maximum zoom; D-0258 is approximately 2km away.
Results: D-0258, along with everything inside the camera's viewfinder, is incinerated.
Background: The camera from the previous experiment is trained at the Sun.
Results: Initially, no change. Approximately 8 minutes later, [DATA EXPUNGED].
Dr. ████'s Note: Oh Christ. Oh [REDACTED] [REDACTED] Christ. Okay. Okay, I think I can fix this. Oh God.
Background: Dr. ████ uses the calendar function on his smartphone.
Results: [DATA EXPUNGED]
//O5 Note: Dr. ████ has been administered Class-A amnesiacs and transferred to work at Site-██. The object termed "SCP-7777" has been located using GPS data from his smartphone, and the construction of Site-77 is now underway. Although there are no records of any of these experiments having been carried out (yet, I presume), initial properties of the object appear to be in line with what has been described by Dr. ████. Therefore, absolutely no experiments involving SCP-1737 are ever to take place. //

This is carbonCore's sandbox.
Object class: Euclid
Special Containment Procedures: SCP-XXX is to be stored in a standard 5m x 5m x 5m containment chamber lined with a thick (~5cm) layer of non-synthetic rubber. It must be suspended away from all solid surfaces by means of electromagnets. Research may only be done in SCP-XXX's chamber, and only under constant surveillance.
Any additional instances of SCP-XXX discovered must be disposed of immediately (slagging followed by alloy separation via ██████ process). All additional instances are to be brought back to Site-██ for research and containment (See Addendum 1).
Description: SCP-XXX appears as a SAE Grade No. 5 steel bolt, such as used in many buildings with a steel or concrete frame. It is made from a medium-strength steel alloy, consisting of 97.5% iron, 1.2% tungsten, and 1.3% unknown substance.
Its effect is not readily apparent, and may not be apparent until several years after installation; in a laboratory environment, it may only be detected with scanning-electron microscopes. SCP-XXX vibrates at a nanoscopic level, in a complex but structured set of frequencies ranging from ████ hertz to ███ hertz. These vibrations crystallize surrounding non-biological[[!footnote]] Materials such as wood and bone appear to be immune. Vulnerability to SCP-XXX seems to depend on the target matter being homogenous at a microscopic level, and to have a certain degree of hardness. [[/footnote]] material into a visually identical but highly brittle version of itself. This effect spreads at an approximate rate of █ meters per year (variable; see Addendum 1). The resulting crystal (SCP-XXX-1) exhibits piezoelectric properties comparable to quartz, enabling it to carry SCP-XXX's vibrations to indefinite distances. A single instance of SCP-XXX is able to "convert" a building of any size to SCP-XXX-1 given enough time. The possibility of SCP-XXX-1's transmission through sewer pipes is not to be discounted; repeated reports of pipes bursting under nominal pressure conditions must be thoroughly investigated. If possible, the conversion of an entire city the size of ████████ to SCP-XXX-1 is estimated to take ██ years.
SCP-XXX was found to be the only item unaffected by crystallization SCP-XXX-1 in a section of [DATA EXPUNGED] rubble, on █/█/2001. The nearby [DATA EXPUNGED] also contained a destroyed instance of SCP-XXX. Analysis showed that both objects were installed sometime in 199█, limiting the exposure radius to approximately █ meters; nevertheless, it was enough to weaken the concrete for [DATA EXPUNGED].
Addendum 1: Careful analysis and observation of SCP-XXX's vibrations reveal that crystallization occurs at a random and inconsistent speed, with a variation of ██ centimeters per year. It is theorized that the unknown substance found in the alloy does not directly cause the vibrations, but reproduces them by resonating to a ██████ field. Attempts to triangulate the source of the field using a single SCP-XXX failed as the source appears to be highly mobile. Any additional instances of SCP-XXX must be brought to Site-██ and then moved to controlled locations around the world (see document XXX-516-WK for a list of possible locations) to allow precise triangulation.
Item #: SCP-XXX
Object Class: Safe
Special Containment Procedures: SCP-XXX may be kept in a keypad-secured safe inside a 5m x 5m x 5m containment cell, which is also to be used for any experimentation done with SCP-XXX. The containment cell's doors must not open unless SCP-XXX is placed back inside its safe. The cell and the hall immediately outside it are to be kept under constant video surveillance, rigged to automatically initiate Code Yellow alarm upon any malfunction. Due to the difficulty in detecting and tracking it, SCP-XXX is not to be taken outside its containment chamber under any circumstances.
Description: In its inactive state, SCP-XXX resembles a white, largely featureless plastic mask. In this state it appears to be inert and safe to handle. Its anomalous effect activates only when it is worn.
When donned by any human subject, the mask immediately morphs to take on the exact form and colour of the wearer's face. This ability is active, and the mask mimics facial movements, effectively becoming invisible when worn. Observation through recording equipment causes minor noise in the image, especially prevalent if the wearer is engaged in conversation or any other activity requiring SCP-XXX to morph continuously. No expected electromagnetic fluctuations have been recorded during these malfunctions.
At no point is SCP-XXX's wearer suffer any of its effects in any way; all anomalous effects manifest only in other people with whom the wearer interacts. Direct visual short-term (less than 2 minutes) contact with SCP-XXX in its active state causes mild paranoia, generally described as being watched, or vaguely feeling another presence in the room. These effects continue for 10-15 minutes, and dissipate entirely soon afterward. If the subject converses with SCP-XXX's wearer for more than 5 minutes, the paranoia becomes progressive, and can be divided into 4 distinct phases.
- Phase 1: Intense persecutory paranoia. Subject reports feeling like they are being watched. If allowed, subject may search their surroundings in an attempt to find whoever/whatever they feel is watching them. This phase may last anywhere from 10 to 30 minutes. Towards the end of this phase, subject will react to imaginary voices, such as with "What?" or "Who said that?" The voices may be reported as whispering the subject's name, or commenting on his thoughts or actions.
- Phase 2: Initial hallucinations. Subject will begin pointing out faces on nearby surfaces. On average, this phase lasts 1 hour.
- Phase 3: Intense hallucinations. All faces are now reported as being concentrated directly on the subject; new faces are immediately seen at any new location that the subject is taken to. Subject is able to hear their speech clearly (confirmed to be distorted projections of SCP-XXX-1's thoughts). While still identified as SCP-XXX-1, the faces are deformed to take on predatory ("demonic" according to some subjects) characteristics. By this point, subject is in severe psychological distress. Due to the threat of intense closed-eye hallucinations, most subjects resort to staring at any bright light source, blinding themselves if the source is sufficiently bright, as faces are reportedly more difficult to make out in the light. As this stage progresses, subject has increasing difficulty telling apart hallucinations from reality, and may become unresponsive. Heavy doses of antipsychotics may be required to evoke a response from the subject. This phase progresses over the course of 10-11 hours.
- Phase 4: Stupor. Subject assumes a fixed position, usually fetal, resisting attempts at being moved; this condition is clinically similar to gegenhalten, a subtype of catatonia, and cannot be treated with any known medicine. Subject does not react to any outside stimuli, including those that usually result in severe pain (i.e. intense heat, electrical shock, vivisection). Despite this, ECG scans indicate that brain activity does not entirely cease, and most stimuli do result in some elevated activity in the part of the brain associated with the affected sense. This phase is indefinite and irreversible, theorized to be the result of neurological damage sustained during the previous three phases rather than a direct effect of SCP-XXX. Subject's muscles gradually stiffen, causing death by suffocation within 24 hours.
At no point does SCP-XXX-1 experience any anomalous effects. Furthermore, he or she always remains conscious of the fact that he or she is wearing a mask. If SCP-XXX is taken off at any point during phases 1 through 3, subject may recover in time by themselves, or by application of amnesiacs (recovery rate 7# percent). Putting SCP-XXX back on after taking it off once will not produce hallucinations in the subject, unless the subject makes contact with SCP-XXX-1 once again, and engages in conversation for at least 5 minutes. Then the effects start from Phase 1 and continue normally.
Item #: SCP-XXX
Object Class: Keter
Special Containment Procedures: SCP-XXX-1 and SCP-XXX-2 are to be contained in furnished quarters at Temporary Site-&& (currently built into the summit of Mount &&&&&, Tibet), and must not be separated from each other at any times. There are to be no sharp objects, no objects which could constitute a choking or strangling hazard, and no easily breakable objects inside the quarters. Quarters must be decorated in bright colours and wallpapers with anthropomorphic animals and cartoon characters. All corners must be fitted with rounded rubber child guards. Additionally, the following items must be made available to SCP-XXX-2:
- Plastic 'mining helmet'
- Plastic 'pickaxe' with no sharp points
- Rock with flat bottom and no sharp points weighing 120 kg or more
- 10cm x 4cm toy bed with 1cm x 1cm cotton pillow and 8cm x 4cm cotton blanket
- 'Barbie' toy dining kit
- Coloring book with edible pages and non-toxic crayons
Additional items may be provided as requested by SCP-XXX-2, as long as they are child-proof and pose no security risk. Temporary Site-&& is to be re-supplied with food, water, and any requested items on a weekly basis via helicopter. Exactly four (4) security personnel are to remain on-site at all times, rotated one at a time every month.
Following Incident XXX-A1, absolutely no research is to be carried out on SCP-XXX-1 or SCP-XXX-2. Accordingly, Temporary Site-&& should not have any scientific or overly expensive equipment.
Due to its size and nature, SCP-XXX-3 cannot be safely contained. Fifteen (15) teams of seismologists from stations on every continent are to track and record all movement of SCP-XXX-3. Sudden changes of course followed by acceleration must be immediately recorded and relayed to personnel stationed at Temporary Site-&&. If SCP-XXX-3 continues accelerating for more than 2 minutes, any currently inhabited sites in its path must be immediately evacuated.
Description: SCP-XXX consists of three objects: SCP-XXX-1, a knitted plush toy in the shape of an unidentified anthropomorphic creature holding a pickaxe; SCP-XXX-2, a Caucasian male in his early 20s, somewhat overweight, severely mentally retarded; and SCP-XXX-3, an autonomous drilling / boring mechanism 10 meters in diameter and 200 meters in length.
SCP-XXX-1 is an ordinary Amigurumi toy in the shape of an unidentified anthropomorphic creature holding a pickaxe.
Addendum: [Optional additional paragraphs]
Item #: SCP-XXX
Object class: Safe
Special Containment Procedures: SCP-XXX is to be stored in a sealed container, secured in a standard safe with a keypad lock. Inside the container, SCP-XXX must be immersed in an inert gas such as helium or argon. SCP-XXX is never to be touched with bare skin; all handling is to be done with steel calipers.
If SCP-XXX is accidentally lodged inside the skin, removal by the affected personnel must not be attempted. Affected personnel are to seek specialized medical attention immediately. SCP-XXX is then to be removed together with all tissue surrounding it in a 5 mm radius. SCP-XXX must then be cleaned with sufuric acid and restored to its containment vessel.
Description: SCP-XXX is a Circle Hook, a type of fishing hook, 2 cm in length. It is made entirely of stainless steel. Its anomalous effects come from microscopic coating covering most of the tip of the barb, made of a metamaterial of unknown composition. The coating is a single strand of that metamaterial, wound in coils around the barb, itself made up of coils of itself (a recursive structure incremented up to 7 times at some places). It exhibits self-duplicating capabilities dependent on organic molecules.
When SCP-XXX is lodged inside any living being, the strand anchors itself below the skin and begins catalyzing surrounding organic molecules into a very viscous substance made up of complex recursive polymers at a near-instantaneous rate. Polymers created directly by the coating strand exhibit some of its self-duplicating qualities, but the subsequent copies contain errors, and lose self-regeneration in a radius of up to 2 milimeters away from the original strand.
Effectively, if the removal of the fishing hook is attempted by pulling it out, the converted biological matter gets pulled out along with it. The strand duplicates itself aggressively as it is pulled out in both directions — to compensate its length being pulled out, and further into the organism in the direction of more biomatter to convert. See experiment logs for more details.

Item #: SCP-1300
Object Class: Safe
Special Containment Procedures: Object is to be contained within a 5m x 5m x 5m containment chamber. Access is denied to personnel below Level 3 clearance. SCP-1300 is only to be used for research purposes.
If consenting terminal cancer patients are used as subjects, they are to be administered Class-A amnesiacs upon the successful completion of the experiment (or if they choose not to participate at any point). Victims of an unsuccessful operation are to be incinerated. If the next of kin requests the deceased's body, a cover story is to be fabricated justifying the incineration of the corpse. The ashes may then be released to the next of kin.
No change in procedure should be required if D-Class personnel are used.
Description: SCP-1300 is an old dentist's chair. The chair itself is quite unremarkable; SCP-1300's anomalous properties originate from the hydraulics column underneath it, normally used to control the height of the chair. The column is opaque to x-rays and other scanning methods. To date, all attempts to open the column have been met with failure.
When a human subject settles into the chair, four mechanical arms with blunted heads emerge from the column base and hover over the body of the subject, appearing to "scan" them through unknown means. If the subject leaves before the inspection stage is complete, the arms will linger for a few minutes and retreat inside the hydraulics column.
Locations on the stomach and the neck appear to be preferred by SCP-1300, although the exact location widely varies between individual subjects. Upon finding a suitable location, each arm's head releases a number of surgical instruments, including lasers, needles, and tubes. The subject is administered a local anesthetic and a paralytic agent. It is unknown how SCP-1300 restocks its pharmaceuticals, but given its method of operation, the conversion of [REDACTED] the likeliest source. See Addendum 1 for more details.
After the subject is immobilized, the arms create small incisions near the injection sites and insert a number of tubes inside. The tubes are guided through the subject's body to any foreign objects located within. These include malign or benign tumors, lodged objects, pacemakers and deep-brain stimulators, and false teeth. It is unknown how SCP-1300 determines which objects are foreign to the subject's body. Analysis of trace substances left over by SCP-1300 reveals the presence of several types of chemical scissors (such as nucleases and ligases), which could reasonably be used to [REDACTED] and re-construct the body based on that information. SCP-1300 does not consider objects smaller than approximately 500 micrometers.
Upon reaching a foreign object, SCP-1300 will pump an unknown enzyme through the tubes, dissolving the object. The resulting liquid is then drawn through the tube into SCP-1300; the liquid appears to be inert and nontoxic. Upon removing all identified foreign objects, another fluid agent is pumped inside which repairs damaged organs, or assumes the shape and function of missing ones. After finishing the process, the tubes retract, and the incisions are closed with surgical lasers. Following the completion of the operation, the arms shut and retreat inside the hydraulics column. The operation is reported to be painless, but some subjects find the paralytic agent and the sensation of the tubes inside their body to be highly unpleasant.
While highly effective at treating most kinds of cancers and many kinds of physical trauma, SCP-1300 is unable to cure bacterial or viral infections. Due to its lack of object resolution below 500 micrometers, some cancerous cells may remain in a subject, leaving a chance for later re-emergence. In addition, the tissue repair and replacement technique is imperfect, sometimes resulting in malformed but partially functional organs, and rarely in malformed and dysfunctional ones. SCP-1300 will not repair organs which it has already repaired or replaced itself. [DATA EXPUNGED] All testing with brain-damaged subjects is prohibited.
Addendum 1: SCP-1300 will unpredictably undergo a change in functionality (henceforth referred to as beta-state) immediately following the administration of the paralytic agent. A very small amount of modified dissolving enzyme is injected, causing a destructive chain reaction which renders internal organs into a semi-viscous substance similar to that observed during regular operation. The resulting slurry is siphoned back inside SCP-1300, replaced at approximately the same rate by a foul-smelling red liquid composed of disorganized organic molecules.
The paralytic agent prevents the subject from moving, speaking, or changing their facial expression; an increase in ocular, cardiac, and respiratory activity indicates that the subject is conscious of SCP-1300's activity. As the chain reaction occurs too rapidly to be stopped by any available means - invariably ending in death - and beta-state appears to be intentional and possibly essential to the device's continued operation, it is recommended that the subject be administered a dose of barbiturates to induce a coma until expiration. Depending on the subject's size, beta-state may last up to 5 minutes. In █ cases, subject's body burst upon being over-filled with the beta-state biomatter.
It is difficult to predict when SCP-1300 will enter beta-state. Some correlation between the difficulty of the preceding operation(s) with the time until beta-state activation has been observed. In one case, following six (6) wide-spread T4 tumor operations requiring multiple organs to be repaired or replaced, SCP-1300 was presented with a dismembered subject on life support. SCP-1300 attempted to replace the missing limbs, as expected. 15 minutes into the operation, however, SCP-1300 ceased functioning. After 5 minutes, it entered beta-state and consumed the subject's organs.
Item #: SCP-XXX
Object Class: Euclid
Special Containment Procedures: SCP-XXX may be secured using the original measures left by █████ Mining Company within the mine itself. The outside entrance to the mine is to be guarded and locked using a keypad combination lock.
Personnel entering the mine are required to wear a Level A Hazardous Materials suit due to high levels of sulfur dioxide contaminating the mine. All exploration teams must contain at least one D-class personnel, who is to stay at the rear of the team at all times.
Description: SCP-XXX is an entity inhabiting the caves adjacent [REDACTED] Mine near [DATA EXPUNGED], Ural Mountains. It is known that SCP-XXX is sentient and capable of using tools — a number of messages have been found scrawled into the rock inside the cave system proper.
SCP-XXX actively avoids contact, as no expeditions have been able to locate it as of yet. It becomes active only when any individual (or group of individuals) attempt to leave the mine. SCP-XXX will target the last individual to attempt to leave the mine and seize them, quickly retreating into the cave system. Exploiting this tendency, a number of D-Class personnel have been outfitted with tracking and recording devices, and asked to enter and leave the cave system (alone). From these experiments, it has been determined that SCP-XXX is capable of moving at speeds exceeding ██ km/h while carrying ███ kg of weight. Due to SCP-XXX's mobility, tracking and recording hardware ceases to transmit 5-7 seconds after contact, unable to penetrate the bedrock. Attempts to kill SCP-XXX by rigging D-Class personnel with explosives have been inconclusive (see Exploration Log XXX-01).
[REDACTED] Mine has been abandoned following a cave-in that exposed a vast cave system, which caused unusually large amounts of sulfur dioxide to flood the mine. Eight workers were killed. Only five bodies have been recovered, however, as SCP-XXX interfered with rescue operations. Following the disappearance of search and rescue personnel, the Foundation secured and sealed the mine.
Exploration Log XXX-01
Agents N███ (referred to as Agent N) and A█████ (referred to as Agent A), Dr. H███ (referred to as Dr. H), and D-0851 are assembled into an expeditionary force to explore the depths of the [REDACTED] Mine. Both agents are armed with automatic [REDACTED]. D-0851 is armed with a 6-in knife. Unknown to D-0851, one of his oxygen tanks had been replaced with a remotely triggered high-explosive charge to be detonated in case of capture.
All members of the expedition are outfitted with head-mounted cameras and audio transceivers. As the bedrock is too thick to penetrate with regular radio transmissions, a series of radio relay nodes are to be installed at regular intervals into the caves.
Dr. H: (through static) …make me out, Command?
Command: Please repeat, Dr. H.
Dr. H: [REDACTED] this wiring mess. Relay node now operational. Command, can you make me out?
Command: Loud and clear.
Dr. H: OK. Attempting to establish video contact.
Dr. H's head-mounted camera flickers on. The team is assembled at the end of the mine tunnel, by the fissure leading to SCP-XXX's caves. Image is corrected to compensate for the yellow fog of sulfur dioxide. Agents A and N perform successful sound checks and inspect their weapons. D-0851 is peering into the fissure.
Command: Video feed received. Please continue with the operation.
The team enters the fissure. Light sources installed by rescue workers appear to have been degraded, and no longer work. All members of the expedition activate their floodlights, illuminating the unusual smooth and perforated structure of the cave system. Agent A takes point by the fissure, while Dr. H installs a set of four closed-circuit cameras just outside the fissure to monitor the entrance. Agent N and D-0851 are examining one in a series of many hollow channels leading away from the main tunnel, this one located on the ceiling.
**D-0851: I bet it's a giant mouse. (looking around) This place looks like Swiss cheese. Did anybody bring a mousetrap?
Command: Please clear the channel, D-0851. Dr. H, are you ready to proceed?
Dr. H: The signal from the
Head-mounted cameras are turned on. Dr. H███ installs a set of four closed-circuit cameras in the ceiling of a spacious chamber near the entrance, to attempt to capture SCP-XXX on video as it attacks D0851. Both Agents and D0851 are proceeding forward into the cave, with Dr. H███ catching up as soon as the last camera is set. D0851 moves into position behind Dr. H███.
30 meters into the cave system. Ceilings are high enough to be passable. Lighting equipment installed in the cave by rescue personnel is broken beyond this point; all personnel turn on their flashlights. Dr. H███ installs the first relay, and the expedition continues inward.
Agent A█████'s light slides over a jagged rock feature in a side tunnel, and the team is directed to investigate. After installing the next relay, Dr. H███ inspects the feature. Close examination reveals the word "LONELY" scratched into the stone. Traces of black matter are seen deposited in the grooves making up the letters. Dr. H███ collects a sample, and the expedition is requested to proceed down this tunnel. D0851 comments on the feature as "creepy" and takes out his knife.
Soon after placing another relay, D0851 is startled and reports hearing a sound. Audio is clear, but no extraordinary sounds are heard. No one else on the team reports hearing anything unusual. D0851 claims he has heard whispers. The team is instructed to continue; D0851 keeps the knife in his hand.
Four more messages are found, each containing black residue: "BIDING", in a 2-meter deep crevice; "B R D" on a wall, illegible, mostly scratched out; "WHY", repeatedly, over a black stain of unknown origin (sample collected); and "DAYS", mostly scratched out. Two more relays are placed as the video feed becomes progressively grainier.
Two minutes later, D0851 again mentions hearing whispers. A low hissing is heard over the audio, and D0851 begins coughing violently. The rest of the team converges over D0851. Dr. H███'s camera shows a small tear in D0851's breathing gear, which Agent A█████ attempts to repair immediately. Despite his efforts, D0851 expires quickly due to sulfur dioxide poisoning. Dr. H███ removes the rigged gas container and leaves a radio relay near D0851's corpse. The remaining team requests how to proceed; permission given to return. All contact is lost 3 seconds later.
Audio and video feed cuts out for the next 10 minutes and 34 seconds. Immediately prior, a small vibration is detected in one of the cameras Dr. H███ installed near the entrance, as if shaken by its base. No other anomalous activity is caught by the cameras.
Audio contact is re-established as the team approaches the entrance. Dr. H███ reports everything to be in order, and apologizes for getting lost. Video contact is re-established close to the first relay, which is found on the floor, smashed to pieces. Eight meters further towards the entrance is a message carved into the floor, which was not seen when the team first entered the mine. Message reads "DONT GO".
Agent N███ requests a D-Class to be sent into the mine to follow the expeditionary force out to prevent loss of non-expendable personnel. Request is denied on the basis of lacking additional hazardous materials suits. Expedition is told to proceed carefully. There is a faint scratching noise coming from the direction of the exit.
Soon after the expedition comes into view of the cameras installed previously by Dr. H███, the feed from those cameras cuts out. The expedition is informed of this. Dr. H███ freezes and backs closer to a nearby wall, as both Agents frantically search the chamber to locate SCP-XXX. There is no trace of SCP-XXX, and Agent A█████ inspects the camera system while Agent N███ takes point near Dr. H███.
The battery powering the cameras comes into view. It is badly vandalized, placed on top of a flat stone. The word "STAY" is carved into the plastic of the battery. The expedition is instructed to leave all non-essential items behind and attempt to exit by running, with Dr. H███ in front, Agent A█████ in the middle, and Agent N███ in the back.
Blaming "gut feeling" later, Agent N███ detonates the remote charge just before coming out of the mine. The resulting blast throws the team out. Agent N███ sustains heavy injuries to his back.
Analysis of the samples reveals that the black matter was carbonized human bone. Samples collected from the black stain turn out to be regular soot.
Item #: SCP-XXX
Object Class: Safe
Special Containment Procedures: SCP-XXX may be kept in a 35cm x 35cm x 35cm fiberglass cube with walls at least 8mm wide that is padded with a thick layer of black leather inside and outside. The leather is to be attached to the cube with polyepoxide. The cube may be opened and closed with a metallic hinge mechanism. It may be kept locked with a simple combination lock and stored in secure storage among other Safe SCPs. Observational research may be conducted on the object at any time, as long as it remains within the box, and the box is not opened. Experiments that involve removing SCP-XXX from its container require approval from the Site Director.
Description: SCP-XXX is similar in appearance to a turned-on 60W incandescent light bulb. It was recovered from the wreckage of ██████ Cold Springs Fitness Centre following Incident XXX-1. An employee of the club that was absent during Incident XXX-1 reported that the object was already noted among the staff for being apparently impossible to turn off, but this was attributed to faulty wiring rather than any anomalous properties. Due to the object being located in a high-traffic area, a decision was made to leave the object alone until it burned out.
Despite its appearance, SCP-XXX is not a light bulb at all as it seems to lack any visible filament. Access to electricity has no observable effect on its function. The source of its glow is a walnut-shaped core which has been determined to emit small amounts of radiation across the whole electromagnetic spectrum, the strongest being in the visible light range. SCP-XXX weighs exactly as much as an ordinary light bulb of its size without filament. It is difficult to determine the core's features and composition without further destructive testing. 05 note: Attempts to remove the core from inside its hull are expressly prohibited at this time.
SCP-XXX's anomalous effect acts on most solid and opaque objects illuminated directly by its visible light for at least 3 minutes and 17 seconds. Affected objects undergo a 2-week period within which they will appear to lose up to 20% of their weight, despite not actually losing any mass. Approx. once every six months, SCP-XXX's glow rapidly intensifies into a brief, very bright flash. Following this, every previously affected object caught in its light instantly becomes inversely affected by gravity and starts "falling upwards", eventually leaving Earth's atmosphere and the Solar System.
SCP-XXX appears to be completely immune to its own effect.
Site examination: Compiled by Agent Fisher, 30 minutes after object recovery.
Cold Springs Fitness Centre is located 3km east of ███████, ██████. It is approximately 500m away from the main road, surrounded by trees. Despite its relatively remote location, the club enjoyed a recent surge of popularity due to its privacy and word-of-mouth rumors that exercising there was highly effective for weight loss.
Numerous trees are missing from around the club, leaving behind disturbed earth associated with uprooting. Some seem to have chunks torn from them, and some are pushed around the recently-expanded parking lot by wind, apparently reversed only partially. Pavement in the parking lot has been torn off in strips with rough edges, where the outermost fragments of the pavement stick up and outwards. Locations of destruction outside the club are consistent with the positions of windows, and SCP-XXX's projected radiation through those windows from its original location. The destruction radius extends to approximately 82 meters from the object, although its electromagnetic radiation stays visible and coherent over much longer distances. A circle can be drawn around the incident location, connecting the farthest points of SCP-XXX's effect.
Most of the club's ceiling is missing. Intact beams show signs of metal fatigue, suggesting that the ceiling quickly "sagged" upwards, and then was torn out. Walls are partially destroyed; those that previously had some object obscuring them from the direct line of sight with SCP-XXX remain intact. Interestingly, while some windows have shattered from the physical forces following weight reversal of the surrounding architecture, they are all present and have not been affected by SCP-XXX.
The majority of the club's training equipment is also missing. A few devices "hang off" exposed beams and support structures that prevent them from "falling" into the sky.
The staff cafeteria is the only room on the main floor surviving for the most part. The ceiling is dotted with cutlery lodged within it, and the table itself "lies" nearby on its side, close to the upper edge of the far wall. Glasses and drinks are broken and spilled over the floor. Non-transparent dishes, broken or intact, are affixed to the ceiling.
The front door — made of glass — appeared to have been deformed during structural shocks such that it became impossible to open. An approx. 30cm x 50cm hole in the door has been made by an object thrown from the inside, as indicated by broken glass lying outside. Pieces of clothing, tissue, and blood trailing upwards from the hole appear to indicate that someone attempted to leave the already partially destroyed building through it.
No survivors have been found, although most missing persons were detected several hours later in Earth's upper thermosphere. The only creature, living or otherwise, recovered from the incident site was a dog that had been tied outside the front door, identified as belonging to a regular at the club. It was kept earth-bound, and was eventually strangled, by its leash.
