Special Containment Procedures: |
REVISION 3 |
SCP-148 is to be stored as 120 cast ingots, each of which weighs approximately 10Β kg at time of writing. Ingots of SCP-148 may not be housed at the same site as any SCP (due to the potential for unforeseen interactions); otherwise, said ingots should be distributed equally among acceptable Foundation facilities. The mass of each contained ingot of SCP-148 must be measured and reported monthly. |
Under no circumstances should any SCP with mind-affecting or extrasensory properties come into contact with SCP-148. In the event of such contact, the immediate area must be evacuated and the affected sample of SCP-148 detonated remotely. |
Personnel are not to be assigned to SCP-148 for a period of time longer than three weeks. Any personnel assigned to SCP-148 are to be given regular psychological evaluations. |
Description: SCP-148 is a metallic substance, composed of a variety of known and unknown elements. The total mass of SCP-148 on hand is approximately 1.1 1.2 tonnes. SCP-148 has a gray-green color with a bluish tinge and oxidizes readily in the presence of water. SCP-148 has a melting transition point of approximately 4500Β°C and a boiling transition point of approximately 9000Β°C. SCP-148 has a density of 6.20Β g/cm3 6.76Β g/cm3 and qualifies as HRC 39 in a Rockwell hardness test. It exhibits material properties, such as strength, ductility, and workability, similar to platinum. |
SCP-148 is composed primarily of platinum and iridium, the two composing 62% and 20% of its mass respectively. In addition, several other known metals are present in its composition, including iron, cobalt, and copper, which collectively make up 16.5% of SCP-148βs mass. However, given the mass of the material, it is believed that there are other substances not detectable by mass spectrometry or other means. Images of SCP-148 taken with a scanning tunneling microscope show gaps in its lattice that, under normal circumstances, would be filled with other materials. |
SCP-148 blocks or otherwise hinders extrasensory mind-affecting properties of living organisms in proximity to it. This effect, while difficult to quantify, appears inversely proportional to the square of the distance from the subject to SCP-148βs surface and directly proportional to the quantity of SCP-148 in consideration. The range for which this effect is detectable is roughly 0.8 meters per kilogram of SCP-148. |
1.1 tonnes of SCP-148 were retrieved from the metallurgical department of Prometheus Labsβ base facility during the Foundation's sweep of the building. Documents concerned with the project had unveiled that the substance was to be subject to additional development, sold to βββββββββββ, trademarked, and sold as βTelekill Alloyβ. However, due to [REDACTED] and its political fallout, along with the destruction of the Prometheus Labsβ base facility, βββββββββββ has acquired an estimated 1.3 tonnes of SCP-148 and sold it to unknown buyers. Foundation agents and forensic accountants are in the process of tracking the remaining supplies of SCP-148. |
Addendum 148-01 |
Due to its potential for use in containment of mind-affecting SCPs, SCP-148 has been approved for cross-testing with SCP objects. While tests are still in their early stages, tests with low-level anomalous items seem to indicate that SCP-148 will be an effective tool in containing said items. However, it does not appear to affect items whose notable properties are purely memetic. |
Addendum 148-02 |
Beginning ββ/ββ/ββββ, staff reported irrational behavior and poor communication skills among janitorial staff tasked with regular maintenance of SCP-148βs containment.1 After three weeks of increasingly abnormal behavior, two custodians were taken in for questioning and examination. Testing revealed that the aforementioned personnel were incapable of interpreting body language and did not appear to notice the intonation or phrasing of sentences. In addition, the affected subjects were incapable of determining the emotional state or intent of others and demonstrated severely limited vocabulary. |
Further testing has revealed that the language and communication skills of persons with regular contact or extended exposure to SCP-148 will, over time, deteriorate and disappear. It has been shown that, after eight weeks, affected subjects will be rendered completely mute and incapable of understanding or giving nonverbal requests, commands, or other statements, despite showing otherwise normal mental capacity. |
Addendum 148-03 |
A measurement taken on ββ/ββ/ββββ (ββ months after the Foundationβs acquisition of SCP-148) indicated that, despite no increase in volume, SCP-148 has increased in mass by 0.1 tonnes (a density increase of 9.0%). The source of this additional mass is unknown. |
Incident Report 148-ββββ-1 |
To test the limits of SCP-148βs effects and its capacity to change in mass, 0.9Β kg of it was placed on a scale and moved to SCP-βββββs chamber. Predictably, SCP-βββββs [REDACTED] was nullified by SCP-148βs presence. However, the sample of SCP-148 began to grow in mass by upwards of 5 grams per second. After one minute, this rate began to decrease, and SCP-148 ceased to increase in mass forty seconds later, at which point it weighed 1.4 kilograms. It remained at this mass for eight seconds before plummeting to 0.8 kilograms in the space of two seconds. During this time, personnel within sixty meters (twelve times the effective range of SCP-ββββ) began to experience SCP-βββββs effects, albeit at a vastly increased rate, resulting in [DATA EXPUNGED] lockdown until the affected subjects could be removed. |
As of this incident, contact between SCP-148 and any mind-affecting items is strictly forbidden. |
Addendum 148-04 |
Measurements taken since Incident 148-ββββ-1 indicate that the combined mass of SCP-148 is increasing at a rate of [REDACTED]. It is speculated that should a large quantity of SCP-148 undergo an event similar to the sample used in Experiment 148-ββββ, [DATA EXPUNGED]. Containment procedures are under review. |

[ Title: SCP-149 is a breed of mosquito which carries a strain of retrovirus (herein referred to as SCP-149-A) that mutates regenerating human cells into fertilized mosquito eggs.; Genre: Scientific; Tags: 3rdperson; Style: Dark ] |
*** |
Item #: SCP-149 |
Object Class: Keter |
Special Containment Procedures: SCP-149 in any of its instances is to be kept inside a sealed plexi-glass box for observation. Oxygen and a nutrient mist are to be released into the containment cell every two hours. If any instance of SCP-149 escapes its cell, Protocol-42-Charlie is to be brought into effect on any and all contaminated personnel, by order of O5-12, after Incident 149-1. |
Description: SCP-149 is a breed of mosquito which carries a strain of retrovirus (herein referred to as SCP-149-A) that mutates regenerating human cells into fertilized mosquito eggs. SCP-149-A is injected directly into the bloodstream when SCP-149 feeds. The SCP-149-A quickly works on the nucleus of the cells, warping the DNA. The first set of cells bred from these changed instructions closely resemble cysts, and are concentrated in the lining of the esophagus and the sinuses. Upon dissection, however, these 'cysts' are revealed to be filled with SCP-149's larvae, the cysts acting as a protective casing against external forces. SCP-149 appears to go through its maturation cycle in a matter of hours; by the time the subject is able to feel any effects, the first generation of SCP-149 has already grown inside the subject's body. SCP-149 primarily achieves exodus through the mouth and nostrils, occasionally being diverted through the Sphenoid sinuses to escape through the eye sockets. Infection by SCP-149 is fatal, and chance of infection has been estimated to be 50% from one bite. |
Addendum: |
Incident 149-1: An incidence of SCP-149 escaped and infected multiple Class-D subjects, the majority of whom did not report SCP-149's contact with them. Within 5 hours, SCP-149 had matured in these hosts and burst out of them, infecting βββ staff. It was only thanks to the quick thinking of Doctor ββββββ, who sealed sub-levels 12 through 15, that the entire site was not infected. As a response to this, O5 command has created Protocol-42-Charlie, to be used if SCP-149 escapes confinement. |

[ Title: SCP-151 is a 1m x 1.; Genre: Scientific; Tags: 3rdperson; Style: Dark ] |
*** |
Item #: SCP-151 |
Object Class: Euclid |
Special Containment Procedures: SCP-151 should be kept in a locked storage compartment, covered by an opaque cloth. The keys to the compartment should be kept in the custody of the site commander when SCP-151 is not being researched. When research is being conducted, SCP-151 may be kept in a locked laboratory, provided it is always covered when not being used. |
Description: SCP-151 is a 1Β m x 1.3Β m (3 ft x 4 ft) oil painting, apparently from the perspective of someone underwater. A subject who views the painting exhibits no initial effects. However, over a period of 24 hours, the subject's breathing becomes increasingly labored, culminating in the death of the subject. Autopsies reveal that subjects' lungs have filled with seawater. Attempts to halt the drowning process by medical intervention have proven successful in prolonging the life of the subject, but have not stopped nor reversed the condition. |
The painting is not signed, but several names are written on the back. |
Addendum: SCP-151 was found in an antique shop in βββββββββ, βββ, after the Foundation began investigating a series of unexplained drowning deaths. As βββ is landlocked, the Foundation dispatched a team of plainclothes agents after being informed of the nature of the water in the victims' lungs and that the victims had all been discovered on dry land. The agents discovered that the names written on the back belonged to a group of artistically inclined students, all of whom disappeared during a study abroad program in βββββββ. Investigation into their fate is ongoing, and may provide clues as to the nature and origin of SCP-151. |

[ Title: SCP-152 is a large, hardbound book with leather bindings.; Genre: Scientific; Tags: 3rdperson; Style: Dark ] |
*** |
Item #: SCP-152 |
Object Class: Safe |
Special Containment Procedures: SCP-152 is to be kept in a locked chamber in Site-49, henceforth referred to as the "reading room". The reading room is off-limits to personnel below clearance level 2. The reading room will be equipped with one ceiling lamp, one security camera, one scanner-copier-printer (to be restocked with paper and ink as needed), one standard office chair, and one standard office desk upon which SCP-152 will rest. When not in use, SCP-152 is to be turned to its last page, so that any additions made to it can be immediately observed. A single guard will be posted outside of the reading room to deter unauthorized persons from entering the reading room. All personnel are advised to remain quiet if they are near the reading room. |
Description: SCP-152 is a large, hardbound book with leather bindings. The paper inside resembles vellum and is written upon in black ink. The contents of the book consist entirely of a series of entries that describe apocalyptic events, which are not always XK-class end-of-the-world scenarios but invariably deal with the extinction of humanity. The entries are arranged in chronological order, beginning with an unexplained spontaneous failure of the sun in 6000 BC and ending with other events close to the present day. Many of the entries describe apocalypses caused or facilitated by objects that are or were in Foundation custody, or are of a paranormal nature. There are also records of human extinction caused by more "conventional" means, such as nuclear warfare or deadly viral epidemics. Each entry describes in some detail the events leading up to the calamity itself, and the aftermath until the point at which the last human on Earth dies. |
It has been observed that the entries in SCP-152 change to whatever language the reader is most comfortable with, up to the point where the sentence structure can change significantly from reader to reader, or even begin using colloquialisms that only the reader would understand; only the basic meaning of the entries remains constant. If multiple people are looking at SCP-152, it will read in the personal language of whomever began reading first. If no one is directly observing SCP-152, it will display the language of whomever read it last. Rarely, words will appear in the book that do not "translate" and instead appear as horizontally arranged calligraphic characters which have not been matched to any known language. |
To the best knowledge of Foundation historians, most of the information contained in SCP-152 is accurate, diverging only at the point where the apocalypse occurs. In almost all cases, the difference is that a few key decisions were apparently made differently in SCP-152's version of history, leading ultimately to humankind's annihilation. |
SCP-152 resists all attempts to change or write in it. Inks, graphite, charcoal, and other marking materials do not adhere to the pages, and are easily brushed off. Lasers or other heat sources do not burn into the paper. Close inspection has revealed that foreign substances are stopped from actually coming into contact with the pages: at least five (5) micrometers of empty space are always present between the pages themselves and any foreign materials that might come into contact with them. For this reason, SCP-152 does not decay, which also means that it has proven impossible to determine SCP-152's exact age. |
SCP-152 is self-updating, with newly-inked entries and new descriptions of how the last human died appearing at unpredictable intervals, always on the last page of the book; the date that a new entry appears corresponds with the date given in the entry for the death of the last member of the human species. When space becomes an issue, extra pages appear along with the text, and the spine of SCP-152 broadens accordingly. There have been βββ updates to the book since it came into Foundation custody. As with past events, SCP-152 has proven to be up-to-date on current events until a point at which a catastrophe occurs. Because recent entries frequently concern entities or groups of interest to the Foundation, including the Foundation itself, SCP-152 is to be checked regularly for any information of importance. |
Addendum 1: With the acknowledgment made that letting this thing lie around where the public could find it is dangerous to us, is there any real reason to study it? Outdated hypothetical disaster scenarios aren't our concern; we've got plenty of real ones in the present to deal with. -O5-β |
Addendum 2: The book is accurate enough about pre-disaster Earth that it makes a decent guide to the present. Plus, it gives a little perspective on the big picture of what some SCPs could do if they got loose. I think all researchers with clearance ought to read the last 50 pages or so just to drive home how important what they do here is. "For want of a nail," and all that. -Dr. Jansen |
Addendum 3: Jansen, half the entries in the last 50 pages show the Foundation screwing up and killing everybody. -O5-β |
Addendum 4: Like I said, it gives a little perspective. -Dr. Jansen |
Incident Report 152-05: On the night of ββ/ββ/ββββ, the security guard on camera duty noticed that SCP-152 was missing from the reading room. However, by the time she had finished reaching for the switchboard to report this, SCP-152 had reappeared, and there was a new entry on the last page. As this was the fifth such occurrence of sudden disappearance and reappearance (refer to Incident Reports 152-01 through 152-04), a simple test was conducted with a high-speed camera, a sensitive electronic scale upon which SCP-152 was placed, and an alarm set to go off if the weight upon the scale abruptly changed. The next three "updates" to SCP-152 all set the alarm off, and the high-speed camera revealed that SCP-152 vanished from sight for exactly one (1) second each time. |
Addendum 5: I posit that the book isn't actually being "updated" as such⦠It's actually being replaced, and each time it changes we are actually receiving a new edition of it. I would very much like to find out where these are coming from. -Dr. Jansen |

[ Title: SCP-154 is a pair of simple bronze bracelets, completely circular and large enough to comfortably hang off the arm of most people.; Genre: Scientific; Tags: 3rdperson; Style: Dark ] |
*** |
Item #: SCP-154 |
Object Class: Euclid |
Special Containment Procedures: SCP-154 is to be kept within Weapon Locker 8, in Armed-Research Site-47. Personnel wishing to research or use item must submit the required request forms. Anyone attempting to remove the item without clearance, or from outside of the facility is to be terminated on sight. |
Description: SCP-154 is a pair of simple bronze bracelets, completely circular and large enough to comfortably hang off the arm of most people. Spectrograph analysis has proven that the item is composed entirely of copper (85%), tin (11%), arsenic (3%), and traces of other slight impurities (<1%). |
When both bracelets are worn on the same arm, and the wearer concentrates on them with arms extended in a depiction of a traditional "nocked bowstring" pose (achieved by having the arm with the bracelets completely extended in front of oneself, with the opposing arm extended up to the elbow of the fully extended arm), a large, indistinct, incorporeal bow will form in the extended hand, and both bracelets will glow lightly. |
From that point onwards, SCP-154 can be treated as a bow, until the pose or concentration is broken, which results in the bracelets reverting to normal. There is no actual bowstring, but completing the motion of pulling it achieves the same effect. |
When the "bowstring is pulled and released", the bones of the arm will be forcibly ejected from the extended limb, traveling in a straight path at speeds recorded over three hundred (300) meters per second. The missing bones and resulting damage to the arm are quickly regenerated, and the weapon is capable of being "fired" again within minutes. Tests using subjects possessing multiple arms/hands, such as SCP-1884-B1, have demonstrated the ability to fire SCP-154 several times, with the bones of different arms being used with each successive firing. |
The regeneration implemented by the item is limited, only affecting the damage inflicted by the weapon itself. This regeneration seems to be an automatic action, and will continue in almost all situations. Both firing the weapon and the resulting regeneration are understandably painful, and participants which have used the item once are generally disinclined to repeat usage. |
However, there have found to be some occasional abnormalities regarding the regeneration. Most often this manifests simply as minor mutations of the original subject, such as changes in size, pigmentation, and structure of the original organelles. These are an uncommon occurrence, capable of happening during any use of the weapon, though generally tend to occur during repeat usage. |
There are more drastic abnormalities, though these are much rarer, and coincide with highly frequent use. These mutations can range from anything such as the growth of extra joints and digits in the affected arm, to a complete change of the chemical or physical structure of the limb. |
One test subject unknowingly had the bone matter within his arm converted into an unstable explosive compound, only discovering the fact when it detonated, causing two fatalities and three casualties. Another had the entire bone and musculature structure morphed into fully functional serpentine physiology. |
Footnotes |
1. SCP-1884-B was permitted to be used in testing with its approval. SCP-1884-B was able to fire five shots from SCP-154 within a minute. Testing ceased on SCP-1884-B's request following SCP-1884-A becoming distressed due to pain associated with SCP-154 use. |

[ Title: SCP-155 is a complex electronic construct consisting of a highly modified Cray CS6400 supercomputer, a dedicated radioisotope thermoelectric generator, and a device that has yet to be fully reverse-engineered.; Genre: Scientific; Tags: 3rdperson; Style: Dark ] |
*** |
Item #: SCP-155 |
Object Class: Safe |
Special Containment Procedures: SCP-155 is contained in a heat-treated and radiation-shielded containment chamber at Site ββ. Recovered documentation and the reverse-engineered compiler for SCP-155 are available for all personnel with sufficient clearance on Site ββ's secure file server, but execution of programs on SCP-155 may only be performed with prior permission from at least two (2) Level 3 Senior Researchers. Please see Document 155-EXEC-1 for radiation and thermal safety procedures for the safe operation of SCP-155. |
As of Incident 155-08, experimentation on SCP-155 has been suspended pending decontamination of SCP-155's former containment chamber and relocation to a new containment chamber. All tasks intended for execution on SCP-155 must now be triple-checked to prevent the possibility of non-halting execution. |
Description: SCP-155 is a complex electronic construct consisting of a highly modified Cray CS6400 supercomputer, a dedicated radioisotope thermoelectric generator, and a device that has yet to be fully reverse-engineered. SCP-155 was recovered from the basement of Prometheus Labs' primary research laboratory by elements of Mobile Task Force Mu-4 ("Debuggers") following the destruction of the facility and subsequent Foundation intervention. |
When a program and accompanying data is loaded into SCP-155 and executed, SCP-155 generates a spherical temporal distortion field with a radius of approximately 5Β m. Within this sphere of influence the passage of time is rapidly accelerated, resulting in a hyperbolic increase in the effective processing power of SCP-155. Execution begins slowly as the processing hardware of SCP-155 is dated, but its effective processing power approaches infinity after approximately 8 minutes and 14 seconds of execution. From fragments of documentation recovered from Prometheus Labs, SCP-155 was used to perform massive calculation jobs that would have taken months if not years of processing time with conventional computing devices. |
Despite its capabilities, operation of SCP-155 is highly dangerous as heat and radiation generated by SCP-155 are trapped and accumulate during operation, forming a sort of 'event horizon' of energy that is released when execution ends. The execution of programs that exceed six (6) minutes results in enough radiation generated that the containment chamber in which SCP-155 is contained must be decontaminated before research personnel may re-enter. |
Addendum 155-01: Incident 155-08 |
On β/ββ/ββ, Dr. βββββββ entered a flawed program into SCP-155 that resulted in non-halting execution (an infinite loop). After attending researchers and technicians realized the error, an emergency shutdown of SCP-155 was initiated but it could not be fully stopped until execution had exceeded 8 minutes and 3 seconds. At this point, an intense wave of heat and radiation melted through SCP-155's containment chamber, resulting in eleven (11) casualties and the total destruction of the C wing of Site ββ. SCP-155 only received minor damage in the incident, but experimentation is suspended while revised safety procedures are under review and replacement parts are procured to repair components damaged by accelerated aging. |
