 Item number, SCP-172, Object Class, Euclid, Special Containment Procedures. Any personnel wishing to access SCP-172 must receive written approval and undergo a one-hour training session. All interaction with SCP-172 must be overseen by at least one Class 4 operative, who may end the session at their discretion. Any and all records, drawings, or correspondence produced by SCP-172 are to be submitted immediately to Dr. P*** for review. Reasonable requests made by SCP-172 are to be granted after approval by said doctor. SCP-172 is to be allowed out of its containment area with approval, as long as it is accompanied by an armed Class 4 operative. Any personnel are to be stationed at the door of SCP-172. Should SCP-172 attempt to escape, it is to first be asked to cease and desist, and then led back to its containment area. Containment area is to be kept stocked with paper, pencils, and any additional components requested by SCP-172. Tables, chairs, and any additional furnishings requested by SCP-172 are to be provided pending approval by Dr. P***. Upon entering its dormant state, SCP-172 should be placed in its transportation box, until rewound. Description SCP-172 appears to be a human being, 34 years of age, 185 cm or 6'1", tall, black hair and mustache, 175.5 kg or 386 lbs, and of Russian descent. SCP-172's personality is very friendly and intelligent, if somewhat dull and repetitive. SCP-172 prefers dress from the 1860s, and always wears a large ornate key on a long necklace. SCP-172 has never identified itself by any name, and is not upset by being referred to by its designation number. Internally, SCP-172 is a staggeringly complex automaton, possessing over 2 million moving parts and 18 million components at last count. Component parts appear to be made of glass, silk, wood, steel, brass, rubber, and several other substances. Very between this construction and that of SCP-2776 suggests a similar creator or creators. SCP-172 also has several modules that can be installed via a hatch in its chest. These appear to alter behavior, speech, movement, and several parameters based on position in the body cavity and module components. SCP-172 has 46 modules at current count, having built three of these while in Foundation custody. Currently, SCP-172 is loaded with the Engineer module. Modules have been identified by SCP-172 as Caretaker, Soldier, Medic, Mother, and King. Though this is by no means a comprehensive list, under no circumstances are modules to be replaced without O5-level authorization. SCP-172 is powered via a mainspring, which is wound with the key in SCP-172's possession after inserting it into a hole at the base of the neck. SCP-172 can operate for 8 hours on a single full wind-up. SCP-172 appears wholly human when in operation, and is capable of all basic human functions. SCP-172 has no need to eat, breathe, or sleep, but will perform all these functions if allowed to do so. SCP-172 is extremely obedient, and will follow any instructions given to it to the best of its ability. SCP-172 does not view its existence as strange, and asserts that it is human, even when shown its internal components. SCP-172 is also extremely delicate, and great care must be taken to preserve and maintain its function. SCP-172 has also shown a level of mechanical skill nothing short of miraculous. SCP-172 is capable of analyzing and copying any mechanical device it comes in contact with. This was first shown when it became apparent that lots of any kind cannot contain SCP-172. It has also made several copies or upgraded versions of SCP technology, all based on incredibly complex clockwork. Most notably, data expunged. Document No. 172-4R Notes on recovery of SCP-172 SCP-172 was recovered after the Great War, in a chamber below a former vacation home of the Czars. Exposed due to stray bombing, the chamber and its contents were badly damaged. But SCP-172 was found intact in an iron crate, along with many modules, and its key. Item was removed by operatives, and wound up inside testing facilities. SCP-172 appeared to wake up from a deep sleep, and proceeded to greet everyone present in Russian. When Agent F*** shouted in surprise, SCP-172 pushed against its chest, and repeated its greetings in English. SCP-172, when questioned, stated that its last memory was playing with a young boy. The boy left, and SCP-172 began to feel very tired, so it returned to the box. It has no memory of its creation, creator, or name. Item No. SCP-217 Object Class Keter Special Containment Procedures Containment area is to be kept behind two reverse pressure airlocks. Chemical shower sterilization, full contained atmosphere hazmat suits, and 24-hour post-interaction quarantine and testing are mandatory for all personnel entering containment area. Should containment be breached, the blast door for the containment and research area will seal, and Chemical Agent ZER-217-11 will be pumped into the air. Any humans exposed to SCP-217 are to be contained and held for observation. Any items touched by those affected by SCP-217 must be sterilized. Description SCP-217 is a virus, incurable by current means, with a rate of infectivity at 100%. It affects all organisms in the kingdom anemalia, and can be spread via touch or contact with bodily fluid. SCP-217 is very hardy, and can survive for years outside the host body. The process of the infection is very slow, with some subjects going several years before manifesting any symptoms. SCP-217 alters the biochemistry of organic tissue, causing organic matter to rearrange into a form of organic metal. The processes involved with this change are not yet fully understood, but the advanced stages are well documented. A subject will begin to turn into a complex arrangement of gears and clockwork, these taking over for the former biological functions. Advanced stage infection is reported to be very painful, but earlier stages are oftentimes unnoticed, with only vague feelings of confusion, insomnia, and joint stiffness. Hearts are replaced by gears and small tubes, joints by gear networks, eyes by structures not unlike primitive hand crank film cameras, etc. SCP-217 shows first on the outside of the body in all creatures, except mammals. In mammals, it first converts the internal structure before manifesting outside the body. This can cause those infected to go for very long periods of time without knowing of infection. SCP-217 has even been shown to totally convert the inside of the body before showing any externally visible symptoms. SCP-217 has infected several major metropolitan areas in the past, most notably The mental state of those in middle to advanced stages of infection has been shown to be much diminished. Subjects respond in a repetitive fashion, are very dull and mechanical in action, are easily distracted and confused, and appear generally irritable when faced with new problems. In addition, research on a fully converted brain has data expunged. Document number 217-6 Notes on Symptoms Subjects infected by SCP-217 have, at early stages, reported no major symptoms, aside from increased lethargy and a general lack of emotional response. Some have reported a feeling of fluttering or moving under the skin, coupled with a persistent ticking noise. This noise seems most prominent when SCP-217 infects the shoulders, neck, and head. However, it is inaudible if recording equipment is pressed against an affected area. Initial infection of SCP-217 is, as has already been stated, almost undetectable. As the infection advances, subjects will begin to feel sharp, tearing pain in areas that are being converted. It has been compared to a knife wound or a deep muscle tear. It can persist for hours or several days, depending on both the subject and the area affected. The new clockwork organs appear to tear and rip at tissue for a short time, before becoming fully integrated and settling into the surrounding tissue, and this is believed to account for the pain. Areas infected appear to be metal, mainly brass, steel, and iron. Other substances have been reported, appearing to be leather, rubber, glass, wood, and other basic materials. Despite appearances, it is purely organic material and even carries the subject's DNA. Organs and tissues affected appear more resilient than normal, carrying the same strength and density as the materials they resemble instead of normal tissue density. Areas damage to repair over time, but it is much slower than standard human regeneration. Damaged areas can be instantly repaired by replacing damaged areas with new parts of the same type. Testing has shown that there are no ill effects if parts made from normal materials, steel, wood, leather, replace the existing biomechanical clockworks. Most alarming, people infected with SCP-217 can continue for months, even years without being detected. With infection so easy to spread, hundreds could be affected before proper containment could be enforced. Infection appears to spread most quickly in large offices, malls, and other large concentrations of people. Note, anything or anyone suspected or confirmed to be infected with SCP-217 is not to be allowed near SCP-882. Addendum, at this time, cross-experimentation between SCP-229 and SCP-217 is allowed only with O5 approval. Item number, SCP-227, Object Class, Safe. Special Containment Procedures, SCP-227 is to be kept in a climate-controlled room at a temperature of 21 to 24 degrees Celsius and humidity no higher than 10%. Anyone touching the object is required to wear surgical gloves. A supply of these is to be kept with SCP-227 at all times. Food, drink, cigarettes, or any other sources of contamination are not allowed inside the containment area. Loose clothing, hair, or other adornment is not recommended. Only personnel with level 3 clearance or higher are allowed access to SCP-227, although lower-ranking staff are allowed to use the object while under supervision. If SCP-227 needs to be transported to another location, it should be sealed in an insulated airtight container filled with inert gas. Description SCP-227 is a bronze clockwork device measuring 10 cm by 16 cm by 26 cm and weighing 5 kg. SCP-227 is somewhat similar in appearance to reconstructions of the Antikythera mechanism, an incomplete and heavily corroded Greek artifact, thought to date from approximately 100 BCE. Unlike that artifact, SCP-227 was found intact and apparently fully functional. This is partly because SCP-227 was found on land instead of at the bottom of the Mediterranean, but the lack of significant damage is remarkable. Preliminary testing of SCP-227 shows that it may have some ability to repair itself over time. Further testing is pending approval from O5 level staff. SCP-227 has one major dial with three hands on the front face. This dial has several concentric rings which rotate independently. The rear face has two major dials with two hands each. These dials are surrounded by a spiral groove through which some of the internal gearing is visible. A number of smaller dials are arranged around the rest of the object. The total number of these minor dials visible at once varies when the object is in use, as does the number of hands on each dial. There are three small cranks on the right side of SCP-227. Turning any of these sets the moving parts of SCP-227 into action. The top crank causes the most rapid change. Some of the smaller hands have been observed moving at speeds of over 1 rpm. Extended use of the top crank causes SCP-227 to heat up significantly. Personnel are advised to use caution when turning the top crank to avoid damaging SCP-227 or injuring themselves. The middle and bottom crank are used for medium and fine adjustments respectively. The object is covered in a large number of inscriptions. The majority of these are in Attic Greek. However, some are in various writing systems that have yet to be deciphered. These include linear A, Cretan hieroglyphs, and one or more unknown languages. The translatable text is essentially a manual of operation for SCP-227 with the exception of one passage which states, data expunged. The full significance of this passage is under investigation. Early indications are that SCP-227 is an incredibly accurate astronomical computer. Symbols corresponding to the sun, moon, and planets are prominently placed on the front major dial along with many other symbols of unknown meaning. The rear major dials have markings consistent with several ancient calendar systems. These include the calypic, metonic, seros, and sothic cycles. There are also at least two more previously unknown calendar systems present. Addendum, SCP-227-1. Further study has revealed that SCP-227 is able to compute the locations of bodies that were only recently discovered by modern astronomers. For example, one set of hands and markings corresponds to the copper belt object, 50,000 quawar. Quawar is difficult to detect even with the Hubble Space Telescope. How the designer of SCP-227 was able to predict its orbit is unknown. Addendum, SCP-227-2. SCP-227 has demonstrated an ability to predict even aperiodic astronomical events. One researcher was turning the top crank and happened to notice a minor dial appear very briefly. Fine tuning revealed that the minor dial first appears on a date corresponding to the 23rd of February, 1987. This is the date that the Supernova SN1987A was first observed on Earth. Addendum, SCP-227-3. Advancing SCP-227 past the date corresponding to 2,000 quawar is not possible. A force of up to 100 newtons applied to the bottom crank is unable to produce any movement past this date. Testing with additional force has not been authorized due to the risk of damaging SCP-227. When the object is set to this date, a large number of dials and symbols appear which are not seen at any other setting. The meaning of this final setting is unknown. Some researchers believe that this may represent an XK class end-of-the-world scenario, such as a wandering brown dwarf, the so-called nemesis hypothesis, a gamma ray burst, or data expunged. Addendum, SCP-227-4. The date of the final setting on SCP-227 was observed to change once, to a time more than years later than the previous date. The symbols that appeared at this new final setting were somewhat different from the previous one, but their meaning remains unknown. Research into what may have caused this change is underway. Item Number, SCP-341. Object Class, Safe. Special Containment Procedures. The Exhibition Hall of Reliquary Research and Containment Site-76 has SCP-341 on display for all research and command personnel to view. Description. A collection of 11 brass and iron aurories found in a large storage room of a basement at Oxford comprises SCP-341. Each aurory is a rough-scale model of a different extrasolar star system, complete with planets, moons, and one or more suns in the center. A unique clockwork mechanism under each aurory allows the brass models of planets and moons to spin on axis and rotate around each model of its parent's stars. Testing dates each machine to be between 150 to 200 years old, but without any specific markings, researchers have been unable to determine who created them. The aurory collection of SCP-341 was set to be released into the hands of a local museum, until an SCP astronomer with a peaked interest in the discovery recognized one of the aurories, SCP-341e, as star system Upsilon Andromedae A, unique for being a solar twin of our own sun, with hot Jupiter-like planets. Further research has matched five of the 11 aurories with possible known extrasolar systems, including Beta Canum Venaticorum, 37 Geminaurum, HD 98618, 18 Scorpii, One aurory, known as the Wheel of Doom amongst researchers, depicts a similar solar system very reminiscent of our own souls. Though the planets and sun themselves are neither near to scale nor space proportionately, the presence of seven major planets of our own system is fairly obvious, including Saturn and its rings and the tilted side of Uranus. There are also five minor planets included beyond the orbit of Neptune. The aurory is missing a model of Earth, and instead has a free moon roaming through a debris field, similar to the asteroid belt present between Mars and Jupiter. Item Number SCP-429 Object Class Safe Special Containment Procedures SCP-429 is to be kept in a standard Type III hazardous object isolation vault. SCP-429 is not to be handled unless an attempt to operate it is to be made. Care must be taken to avoid inadvertently touching any of SCP-429's controls. Description SCP-429 is a complex device, constructed of brass and leather, designed to fit over an individual's right hand. There are a total of seven controls on SCP-429. One. A lever that fits into the palm of the left hand. This is the main activation control, and is depressed when the subject has finished setting their destination. Two. A round dial near the location control one meets the main device. The exact function is unknown. Three. A six-sided dial at the front of the main device. This appears to be involved in broad location selection. Four. A round dial in the center of the main device. This appears to be involved in fine location selection. Five. A lever across the clock face. The exact function is unknown. Six. A dial on the side of the clock face. This alters the clock face, although the function in selecting destination is unknown. Seven. A switch on the side of the main body, not visible in filed image. The exact purpose unknown. Examination of SCP-429's inner construction reveals a clockwork mechanism connected to the exterior controls, which drives the clock face. On the exact physical duplicates of SCP-429 constructed by the foundation, the controls are either not connected to the clockwork, controls one, five, and seven, or simply alter the displayed time at varying rates. The controls two, three, four, and six. When a subject wears SCP-429, they gain an instinctive understanding of its operation, although they do not gain the ability to convey this information to others. If the subject visualizes a location and follows their instinctual understanding to adjust the controls, the wearer will disappear from their current location and simultaneously appear at the visualized location. Upon arrival, the controls save for one and six return to their original positions. Control one remains depressed until released, and control six adjusts the clock face to local time. After activation, SCP-429 is inert until control one is released. The subject is not perceived travel via SCP-429 is instantaneous. Each subject has reported a prolonged period of paralysis and blindness, equivalent to the time it would take to travel in a direct line between the activation location and destination, traveling at approximately six to ten kilometers an hour. The biological needs of the activating subject progress as normal during this time. Therefore, journeys of more than 510 kilometers are not advised due to the risk of dehydration. Suffocation does not appear to be a hazard, however. The controls are highly sensitive and will move under the slightest pressure. If the controls are altered without the instinctive understanding granted by wearing SCP-429, it will disappear from its current location and reappear somewhere within 1.76 kilometers, taking the individual who altered the controls with it. The time elapsed in such cases appears to be significantly higher than normal, with the activating subject typically arriving in a state of advanced decay. On date expunged, SCP-429 was activated remotely via a robotic arm, equipped with a video camera and a range of sensor equipment. No data of any kind was recorded by any of the equipment, save for the onboard timing mechanism, which recorded an eight-month, five-day and 37-second time lapse. SCP-429 came to the attention of the Foundation after a series of seemingly impossible burglaries. The Foundation examined CCTV footage and noticed an individual, believed to be SCP-429's creator, disappearing from sight shortly before each burglary. The individual appeared to be using SCP-429 for short jumps to access inaccessible locations. The Foundation pursued this individual across three continents over a period of nine years, before the individual was finally found having died of old age due to extensive use of SCP-429 in...
