Item #: SCP-2943 Object Class: Thaumiel Special Containment Procedures: SCP-2943-A is currently within the boundaries of Site-51. A digital display showing the current date and time is to be kept within visible range of this manifestation point at all times. A timer counting down until precisely 8,640 minutes have elapsed since the previous SCP-2943 manifestation is to be kept running at all times, and reset as required. Tests conducted with any SCP-2943 instances are to be catalogued in the SCP-2943 Testing Log. All instances of SCP-2943-1 are to be catalogued according to manifestation time and stored accordingly. New instances of SCP-2943-1 are to be timestamped immediately for ease of cataloguing. Instances of SCP-2943-2 are to be processed similarly to SCP-2943-1 before being transported to Lunar Area-32, to facilitate satellite imagery of the Earth as depicted through each instance, to assist in determining the cause of their manifestations. SCP-2943-2 are to be stored at Site-51 when not in use, separately from SCP-2943-1 instances.

Additional procedures for Level 3 or higher personnel only. Displaying additional procedures. SCP-2943 storage areas are to be frequently inspected for the appearance of SCP-2943-3 instances. The content of SCP-2943-3 instances is to be recorded and available information utilised to prevent the reoccurance of any observed K-Class scenarios. Information regarding SCP-2943-3 instances is restricted to Level 3 or higher clearance. In the event of an impending severe K-Class scenario, Procedure SATURN LAMENT is to be initiated as a last resort. Under no other circumstances whatsoever are any potentially destructive tests to be conducted on any SCP-2943 instances. Procedure SATURN LAMENT: Information detailing pivotal events regarding the imminent K-Class scenario, such as events that directly instigated the event or alternate outcomes that were not explored, are to be left exposed within reasonable distance of SCP-2943-A until an SCP-2943-1 or SCP-2943-2 instance manifests. Once this has occurred, an available SCP-2943-1 or SCP-2943-2 instance that manifested prior to the first event pivotal to the impending K-Class scenario the most recently manifested SCP-2943-1 or SCP-2943-2 instance is to be destroyed by any means necessary.

Sonar image of SCP-3924. Item #: SCP-3924 Object Class: Euclid Uncontained/Neutralised Euclid Special Containment Procedures: SCP-3924 should be monitored via sonar at all times for any atypical behaviour. Records of its courses and speeds should be catalogued. Non-Foundation vessels must remain within 3,500 metres of sea-level while within the Hellenic Trench region. All vessels attempting to, or successfully, surpass a depth of 3,500 metres must be apprehended, questioned and amnestised, if recoverable. Lethal force is permitted if vessels resist apprehension. All manned Foundation vessels must remain above 4,000 metres below surface at all times while within the Hellenic Trench region. All manned Foundation vessels must remain at least 20 km away from SCP-3924 at all times. (See: Addendum III.) Description: SCP-3924 is a mobile, submersible object that roams the hadal zone of the Hellenic Trench region. SCP-3924 typically moves at 40 km/h and at depths of 4,450 to 4,980 metres below surface, but is capable of reaching speeds of 55 337 km/h and depths of 5,250 metres. In all encounters, SCP-3924 has evaded visual observation; because of this, its approximate physical appearance is only known through sonar imaging (Depicted above). SCP-3924 perpetually emits an indeterminate sound, depending on its current “state”; although the sonics change depending on whether or not SCP-3924 is passively roaming or actively engaged in battle, at no point does SCP-3924 cease emitting noise. (See: Addendum III.) Because of SCP-3924’s normal depth, these sound are heavily distorted due to seawater; ongoing audio analysis has identified an ongoing rhythm between the various sounds, suggesting they may be musical in nature. To date, no patterns typical of vocalisations have yet been identified. Whenever a vessel approaches a depth of 4,100 metres below surface while within the Hellenic Trench region, SCP-3924 enters an active state, immediately changing course to intercept and broadcasting an alternate audio signature (unique to this state) directly at the encroaching vessel. This will continue until the vessel rises above a varying depth. If the offending vessel dives below 4,100 metres, SCP-3924 becomes hostile and will attack by use of incendiary torpedoes and/or rising mines; SCP-3924 will become increasingly aggressive in tactics the longer the vessel is below the 4,100 metre threshold, the deeper it gets, and the more aggressive the vessel becomes in retaliation (if at all). SCP-3924 will continue attacking until the encroaching vessel either rises above 4,100 metres below surface, or is catastrophically destroyed; due to the fact SCP-3924’s primary strategy appears to be focused upon rupturing ballast tanks, the latter is the most common outcome. If a vessel rises above the 4,100-metre threshold, SCP-3924 will immediately cease attacking, but will remain in an active state until the vessel rises above a “sufficient” depth. SCP-3924 periodically enters an active/hostile state in the absence of any encroaching vessels; in all such cases, SCP-3924 appears to broadcast, and attack, an indeterminate object/entity between it and the seafloor. To date, sonar has failed to detect any such objects/entities. Addendum I: Incident 3924-A On January 9, 2018, SCP-3924 entered a hostile state and began firing munitions towards the seabed. During this time, a pre-prepared and unmanned submersible was deployed several hundred kilometres away in an attempt to reach the Hellenic Trench seafloor while SCP-3924 was preoccupied. Once the submersible passed the 4,100-metre threshold, SCP-3924 immediately began firing torpedoes in its direction, despite showing no awareness of the submersible beforehand. SCP-3924 made no attempts to intercept the submersible, apparently prioritising the unseen threat below it. After thirteen minutes, SCP-3924 ceased firing towards the seafloor and immediately changed course to intercept the submersible (which had reached a depth of 4,954 metres). SCP-3924 rapidly accelerated to 337 km/h, reaching the submersible within several minutes and destroying it — sonar observation detected portions of SCP-3924’s hull shedding during this manoeuvre. SCP-3924 then ascended to a depth of 4,500 metres and began deploying rising mines in an attempt to damage or sink ships at the sea’s surface; [DATA REDACTED], [DATA REDACTED] and [DATA REDACTED] were critically damaged and sunk. SCP-3924 remained aggressive to surface vessels for a further three hours, after which it resumed normal behaviour. To date, this is the only time SCP-3924 has attacked vessels outside of its active zone. Further attempts to surpass the 4,100 metre threshold are strictly forbidden. Addendum II: Incident 3924-B On April 3, 2018, SCP-3924 again entered a hostile state in response to an undetected threat. Unlike previous renditions, SCP-3924 continuously fired towards the seafloor for 334 consecutive hours , during which it progressively descended to a depth of 5,250 metres. On April 17, SCP-3924 ceased firing and began broadcasting a previously unrecorded audio signature in all directions; three minutes later, SCP-3924 rapidly descended towards the seafloor, but disappeared from sonar detection immediately prior to impact. Attempts to locate SCP-3924 or its wreckage throughout the Hellenic Trench, either through sonar or visual detection, are currently ongoing, but are thus far inconclusive. SCP-3924 tentatively reclassified Uncontained/Neutralised. Addendum III: Incident 3924-C On April 20, 2018, SCP-3924 was detected by sonar within the Calypso Deep region of the Hellenic Trench, approximately 75 km from where it disappeared. Sonar imaging shows that SCP-3924 appears to have suffered catastrophic rupturing of most, if not all, ballast tanks, but is attempting to ascend under (assumed) thruster propulsion alone. Since reappearance, SCP-3924’s behaviour has drastically changed; SCP-3924 will only respond to vessels within a 15 km radius, which it will aggressively fire upon, and SCP-3924 no longer produces any detectable audio. SCP-3924, at its current heading and speed, is estimated to return to its regular roaming zone by 23 March, 2019.

Item #: SCP-2493 Object Class: Euclid Special Containment Procedures (Revision 2): SCP-2493-1 is to be kept at Lunar Area-32 or at its designated containment chamber located 100km away, accessible by high-speed rail. SCP-2493-1 is to wear SCP-2493-2 whenever outside their designated containment chamber, and is to be restricted from attempting to leave their chamber until it is ensured SCP-2493-2 is correctly secured. SCP-2493-1 is to be provided with three meals each day, transmuted into antimatter by use of designated devices received from 2493’. (See Addendum 3.) SCP-2493-1 is to be psychologically evaluated twice weekly, and medication to be administered as required. A list of SCP-2493-1’s requests for updated containment procedures is to be submitted to the Ethics Committee on a bi-weekly basis for review and approval or rejection. Proposals to rescind approved requests are to be submitted to the Ethics Committee; any other attempts by staff to impede approved requests will result in severe reprimands at the discretion of the Overseer Council. The full list of approved and rejected requests are outlined in Document 2493-1; “Approved & rejected requests by SCP-2493-1 for updates to containment procedures.” Special Containment Procedures (Revision 1) Note: These procedures are no longer in effect! SCP-2493-1 is to wear SCP-2493-2 at all times. SCP-2493-1 is to be kept in its modified humanoid containment cell at Lunar Area-32. The cell is to be filled with pure helium gas at a pressure of approximately 20 kilopascals, and kept at a temperature of approximately 280 Kelvin. The interior of the room is to be kept above a minimum of 270 Kelvin, to ensure continued biological function of SCP-2493-1. The interior surface of SCP-2493-1's containment cell is to be padded with a three centimetre thick layer of soft rubber. No sharp corners or points are to be present within SCP-2493-1's cell; all such corners or points are to be removed or padded. In the event of SCP-2493-2 becoming punctured, it and SCP-2493-1 are to be immediately jettisoned from the facility. MTF Gamma-4 ("Blondebeard's Crew") is to be notified to adjust the trajectory of the anomaly as required, and to prevent it from entering the earth's atmosphere and causing a UK-Class Global Irradiation event. SCP-2493-1 is to be supplied at least 2 kilograms of waste matter daily, to a maximum of 10 kilograms. Once weekly, a signal requesting contact is to be sent through the extradimensional anomaly located on the rear of SCP-2493-2 by use of a 4 MHz radio wave. The entity is also to be under surveillance at all times, and any attempts to hinder communication with the entity’s location of origin are to be reported to the site director immediately. (See Addendum 3.) A list of SCP-2493-1’s requests for updated containment procedures is to be submitted to the Ethics Committee on a bi-weekly basis for review and approval or rejection. Proposals to rescind approved requests are to be submitted to the Ethics Committee; any other attempts by staff to impede approved requests will result in severe reprimands at the discretion of the Overseer Council. The full list of approved and rejected requests are outlined in Document 2493-1; “Approved & rejected requests by SCP-2493-1 for updates to containment procedures.” Description: SCP-2493 is the collective designation for two components; SCP-2493-1 and SCP-2493-2. SCP-2493-1 is a male humanoid entity approximately 1.7 meters in height, and weighing approximately 95 kilograms. SCP-2493-1 is composed entirely of antimatter, but physically appears to be an ordinary human. SCP-2493-1 responds to the name of Joe Smith, and claims to originate from an alternate dimension composed primarily of substances with similar atomic composition to his. Psychological evaluation of SCP-2493-1 has revealed that it suffers from nostophobia and an obsession with completing their mission. (See Addendums) SCP-2493-2 is a suit composed entirely of a previously undiscovered and currently poorly-understood substance that SCP-2493-1 refers to as ‘Buffer’, superficially resembling an airtight type 1 hazmat suit. This substance is entirely non-baryonic in nature, uniformly reflects all wavelengths of electromagnetic radiation resulting in a mirrored surface, and is also capable of preventing interaction between matter and antimatter. These properties prevent the contents of anything composed of this material from being examined by use of X-ray scanning, and severely impede physical examination. The material comprising SCP-2493-2 is flexible in a manner comparable to rubber, but has a texture consistent with polished metal. An impermeable barrier replaces the substance around SCP-2493-1’s facial region, serving as a two-way visor. The interior of the suit is also capable of emitting light from an undetermined source, and will do so upon instruction by SCP-2493-1. On the back of SCP-2493-2 is a multifunctional backpack that serves as an air recycler, a method of exchanging resources obtained by SCP-2493-1 for canned provisions, and an airtight input for canned provisions. SCP-2493-1 has never been observed to physically ingest these supplies; the entity states that this is attributable to nanites present within the interior of the suit, which constantly reassemble small sections of food within his mouth whenever available. It is theorized that the device is connected to SCP-2493-1's reality of origin via a stable extradimensional anomaly in the device, as this is the only reasonable explanation of how the provided waste materials can be converted into edible substances composed of antimatter. + Addendum 1: Information Summary - Showing summary. The following is a list of information regarding SCP-2493-1’s origins, obtained during several interviews. It should be noted that the only source of such information is the entity itself, and as such cannot be confirmed to be factual. (See Addendum 3.) SCP-2493-1 originates from an alternate reality (Henceforth 2493’) consisting entirely of antimatter. The society of 2493’ has access to or has developed technology that is significantly more advanced than that of our own, with such technology requiring large quantities of electrical energy to operate, typically exceeding the range of petajoules on a daily basis. Technology within 2493’ approximately 200 years ago 173 years ago produced large quantities of waste materials as by-products of their operation. Such technology has since been adapted to recycle their waste materials. These produced waste materials were transported to a poorly-understood location of abnormal geometry, described as being physically located between two of the three axis present within normal three-dimensional space. After an undefined period of time 40 years the inhabitants of this space began transporting their own waste materials to 2493’, with several described objects exhibiting anomalous phenomena sufficient to be classified as SCPs. This prompted the inhabitants of 2493’ to develop devices capable of severely hindering the transit of such waste material. An unidentified object, presumed to be of abnormal geometric origin, initiated an XK-Class Vacuum Decay within 2493’. Technology developed specifically to counter such a scenario spontaneously activates, protecting a small portion of 2493’ from the event; however, such technology is required to be powered continuously in order to sustain such protection. Numerous working-class citizens of 2493’ have been deployed to alternate realities to obtain matter and transport it back, for the purpose of powering antimatter reactors. + Addendum 2: Recovery interview log - Showing log. Interviewed: SCP-2493-1 Interviewer: Researcher ███ Foreword: This interview was conducted shortly after the acquisition of the entity, before the antimatter nature of SCP-2493-1 had been confirmed. <Begin Log> Researcher ███: What is the suit you are wearing made of? SCP-2493-1: There's no atoms. Why are you detaining me? Researcher ███: We need to ask you some questions. Why do you need the suit? SCP-2493-1: Because you're made of antimatter. One plus negative one equals ka-fucking-boom. Researcher ███: Would you care to elaborate upon your objective? SCP-2493-1: I grab some of your stuff, send it back home. Doesn't matter what it is, as long as I send it back. Researcher ███: What do you require the resources for? SCP-2493-1: Fuel. The explosion makes a lot of energy, which can be turned into electricity. I need to get uhh… two… two? Yeah, two kilograms minimum of antimatter per day. I uh, think that’s how much they said would keep everything powered at least. Or was it five? Researcher ███: What are you referring to? SCP-2493-1: Mainly home electrics, water recycling, food production and vehicle electricity. There’s some more important things too, so could you please let me get back to work? Researcher ███: If you are made of antimatter, aren’t you aware of the ramifications that will occur if your suit is punctured? SCP-2493-1: I die and my employers lose a supply line, it was on the contract. It’s an acceptable loss, considering they can just find another source. Researcher ███: It would be safer to simply send you back. If you cooperate, we should be able to devise a method of sending you back. SCP-2493-1: You don’t need to send me back, I’m fine here. Just let me stay. Researcher ███: Why shouldn’t we send you back? SCP-2493-1: It’s safer here. From what I’ve seen of here, we’ve been ahead of you in regards to technology for ages, but you’ve been able to handle waste much better than we did. We got lazy and sent it off to some vague location between dimensions for a couple of years, but as it turned out there were… things, living there, and seeing as we were fine with sending them our garbage, they seem to have decided to send their garbage to us as well. You know what sort of things that beings from between dimensions consider garbage? <End Log> Closing Statement: Theoretical calculations of the interaction of 2kg masses of matter and antimatter as described by SCP-2493-1 would produce 360 petajoules of energy; in comparison, the Three Gorges Dam in China, the world’s largest power station as of writing, produces 356 petajoules of energy per year. Questioning SCP-2493-1 in regards to the technology necessitating electrical input at this magnitude on a daily basis is currently underway. + Addendum 3: Event logs - Showing logs. On ██/██/██, contact with 2493’ was successfully established by use of a 4 MHz radio wave transmitted through the extradimensional anomaly located on the rear of SCP-2493-2. The superiors of SCP-2493-1 apologized for the extended period of time taken for them to respond, and requested to speak to SCP-2493-1 personally. Several of SCP-2493-1’s claims, as well as additional false claims, were requested for confirmation to ensure that cooperative disinformation could not be attempted; all claims made by SCP-2493-1 (detailed in Addendum 1) were clarified and confirmed as true, with all additional false claims being denied. SCP-2493-1 was allowed to communicate with his superiors, and was noted to praise Lunar Area-32 staff repeatedly throughout their conversation, promoting trading prospects. On ██/██/██, negotiations for trade between representatives of 2493’ and the O5 Council was conducted. It was agreed that in return for digital information regarding assorted 2493’ technology, the Foundation was to provide a continuous supply of matter in the form of waste material. The bulk of this waste material was sourced from the five major ocean gyres and various global landfills. The majority of the information received from 2493’ was oriented towards containment or destruction of anomalous entities, specializing in entities, objects or locations with abnormal geometric properties. Additional information enabled large advances in medical science, and artificial food production. Schematics for an antimatter reactor were also utilized to create the prototype FAM-Reactor. Further negotiations were conducted to obtain controlled amounts of antimatter from 2493’ in return for random samples of modern music. On ██/██/██, Lunar Area-32 received a transmission from 2493’ stating that several devices critical to the continued existence of 2493’ were failing due to physical strain due to their extended usage. The Foundation was informed that while maintenance would delay total failure, 2493’ was expected to be destroyed within a year. Several weeks later a second transmission was received, stating that the devices preventing 2493’ from receiving waste material from the location of abnormal geometry had outright failed, and that 2493’ was now being overrun with severely detrimental anomalous objects. Staff at Lunar Area-32 was advised to prepare to receive several objects essential to ensuring SCP-2493-1’s continued biological function. Several devices constructed of the same material as SCP-2493-2 manifested a short distance outside Lunar Area-32, including a large room with airlock capable of safely containing SCP-2493-1 in a vacuum environment, which has since been relocated away from the Area, connected via high-speed rail and further reinforced. On ██/██/██, a large burst of digital information was received from 2493’, primarily consisting of historic records of 2493’, photographs of various regions of 2493’ and several schematics for devices capable of recycling various non-biodegradable materials into reusable resources. All information received has been archived as required. To date, no further transmissions have been received from 2493’.

Item #: SCP-3492 Object Class: Euclid Special Containment Procedures: SCP-3492 should be contained in a standard humanoid containment cell. SCP-3492 can be supplied with rewards in return for compliance. SCP-3492 must be fed a standard regimen of three meals each day. Staff are advised to exhibit caution while in proximity with SCP-3492, as the spatial distortions it experiences may cause unintentional harm to nearby individuals. Description: SCP-3492 is a Caucasian male human claiming to be named "dicks mcSquigee". DNA analysis has proven inconclusive, as collected samples are subject to microscale replications of the entity’s properties, and will spontaneously demanifest after indeterminate periods of time. SCP-3492 sporadically undergoes prominent spatial and/or temporal distortions centralised upon random portions of the entity’s body. These distortions vary in duration and content, but typically involve one of or multiple of the following: Dislocation of bodily portions to another fixed position relative to the remainder of SCP-3492 ;

position ; Over or underexaggerated movement of bodily portions along a single axis, frequently resulting in the above

Over or underexaggerated rotation of jointed limbs, frequently to physically impossible extents;

(Supposed) rotation or movement of bodily portions along or around unobservable, higher spatial dimensions;

along or around unobservable, higher spatial dimensions; Spontaneous loss of one or more spatial dimensions, resulting in SCP- 3492 converting into a lower-dimensional form;

spatial dimensions, resulting in SCP- converting into a lower-dimensional form; Prominently slowed or accelerated motion of bodily portions ;

accelerated motion ; Apparent motion of limbs independently from SCP- 3492 ;

; Motion of bodily portions occurring in an inverted manner;

Pseudo- precognitive abilities resulting from SCP-3492 briefly undergoing a period of inverted time ; Of note is that affected portions of SCP-3492 appear to be selectively intangible to the remainder of the entity, enabling limbs to pass through other limbs unaffected, and enabling joints to rotate freely upon all axis while affected. Because of this, SCP-3492 does not suffer from injuries related to its effects, but does experience discomfort. SCP-3492 claims its properties stem from the fact it is a component of a partially-functional program developed by the TotleighSoft corporation as a proof-of-concept intended to promote interest in a physics engine being developed. The entity's respective instance of this program (designated SCP-3492-A) has yet to be recovered. SCP-3492 was recovered during the 2017 Electronic Entertainment Expo, wherein it was attending as part of, and maintaining, an exhibition booth catalogued to be reserved for the TotleighSoft corporation. All attending civilians that observed SCP-3492 prior to recovery were amnestised. Interviewed: SCP-3492 Interviewer: Researcher ████ ███ <Begin Log> Researcher ████ ███: Good afternoon, 3492. May I ask you some questions? SCP-3492: Yes, sure. Why not. Researcher ████ ███: Would you prefer if I called y- SCP-3492: NO! No, no, just… the number is fine. 3492 will do. <SCP-3492's right pectoral girdle extends to a length of approximately two meters, displacing the right arm appropriately.> Researcher ████ ███: Very well. You are aware of your condition, correct? <SCP-3492's left forearm rotates rapidly around their elbow joint, passing through the remainder of their arm without difficulty several times. SCP-3492 takes several moments to adjust the position of their arm, allowing them to gesture to their right shoulder with it.> SCP-3492: It's a bit difficult to ignore. Researcher ████ ███: Do you know what is causing it? SCP-3492: TotleighSoft BECAUSE COMPUTERS' ineptitude at their job. <SCP-3492 becomes two-dimensional, losing the axis of width and only being visible from their left or right.> Researcher ████ ███: Could you elaborate? SCP-3492: Have you ever encountered anything produced by TotleighSoft BECAUSE COMPUTERS? Researcher ████ ███: I have. SCP-3492: Then you would know about the inanity of their games, the nonsensical features of such and, most notably, their inability to use any language other than broken English? Researcher ████ ███: Yes. <SCP-3492 regains the axis of width, becoming three dimensional again.> SCP-3492: Well, there's your reason. SCP-3492: swercs smargorp rieht fo rehtona tey nehw esirprus a fo hcum eb t'ndluohS SCP-3492: Oh, pardon me. It shouldn't be much of a surprise when another one of their programs screws up. Researcher ████ ███: You are a computer program? SCP-3492: A sub-program, but yeah. Proof of concept to show how AI's like me run on the main program. Researcher ████ ███: Which is? SCP-3492: A godawful clusterfuck of a physics engine that was supposed to "improve" upon standard spacetime. I basically exist in a bootleg - oh, excuse me. <SCP-3492's bodily features shift and dissipate, preventing the entity from communicating for several minutes. The interview is paused until SCP-3492 regains the capability to speak.> SCP-3492: Damn fourth axis. As I was saying, I'm an AI made by TotleighSoft BECAUSE COMPUTERS used to show off the… "functionality", of a physics engine they're working on. Researcher ████ ███: And this would be the reason your name - SCP-3492: Yes, unfortunately. You can mess with some of my parameters, and you've named me dicks mcSquigee. Could you please change that? Even something bland like John Doe would be fine, just… anything but dicks mcSquigee. <SCP-3492's lower jaw rotates around its joint upwards, disappearing into the skull without resistance. Their speech is not impeded.> Researcher ████ ███: Do you know where your file is currently being hosted? SCP-3492: Well, no, but… the other guy gave it... wait, you DID buy the program, right? Legitimate copy from TotleighSoft BECAUSE COMPUTERS, right? SCP-3492: Did… did you fucking pirate me? <End Log> Interviewed: SCP-2803-A, the CEO of the TotleighSoft corporation, via email. Interviewer: Researcher ███ ██████ <Begin Log> Researcher ███: Could you help me with one of your products? I'm having a bit of difficulty with it. SCP-2803-A: Yes, supporting is avaliabel! Which of our TotleighSoft programes is? Researcher ███: I can't find the original name of it. It's a physics engine that you have released, which comes with a customisable demonstration AI. SCP-2803-A: Not right. How doyou have? wasnt released. Researcher ███: You haven't released it yet? Why not? SCP-2803-A: Noone interested in it. showed it for buisness, but no response. production stopped and employees work onother profit, never sold. How did you get? Researcher ███: We bought it from a store. We can conduct an investigation for you, to find out how this happened, but we will need your cooperation. SCP-2803-A: Yes, will help. What you need? Researcher ███: Can you send us a copy of your development notes and a manual? SCP-2803-A: Yes yes, is attach. Will help anyway! <End Log> Interviewed: SCP-3492 Interviewer: Researcher ████ ███ Foreword: A review of the development notes for SCP-3492 provided by SCP-2803-A revealed that several of the anomalous properties of SCP-3492 were recorded as having been patched in earlier versions of the software, while other properties - most notably, the ability to change the name of the AI - were neither implemented as a feature nor encountered as a programming error. An interview was conducted to question SCP-3492 regarding these revelations. <Begin Log> Researcher ████ ███: Good morning 3492, how are you doing? SCP-3492: About as well as you can be while knowing you're illegal. Researcher ████ ███: I… see. We're working with your creator to find out how you came into our possession, to avoid it in future. Speaking of which, we've come across some… discrepancies, which we would like your help with. Are you willing to help? SCP-3492: I guess. Not like I can get any more illegal. <SCP-3492's left thumb extends until it touches the ceiling of the room, after which it returns to its normal length.> Researcher ████ ███: Ok. You will periodically move along a spatial axis higher than the standard three we exist within, correct? SCP-3492: Yeah, that's what happened the last time we spoke. It just happens whenever it wants. Which is what you get for being ILLEGAL. <SCP-3492's right leg is seen shifting before disappearing.> Researcher ████ ███: Yes, well, are you aware that issue was resolved in one of the earlier versions of your software? <SCP-3492's right leg reappears.> SCP-3492: Really? Well, that's odd. But then again, it's probably back because I'm ILLEGAL. Researcher ████ ███: Well, there's several other anomalies that have been listed as resolved as well, such - SCP-3492: Maybe they weren't fixed in copies that are ILLEGAL. Researcher ████ ███: I would appreciate if you stopped emphasising that point. SCP-3492: What, that I'm ILLEGAL? Researcher ████ ███: Yes. SCP-3492: Well… FINE, I GUESS. [Unintelligible] <What appears to be SCP-3492's tongue briefly emerges from the top of their skull.> Researcher ████ ███: Pardon? SCP-3492: Nothing, nothing. As you were saying. So, a few bits and bobs of me are broken again, so what? What's that mean? Researcher ████ ███: Well, there are also several aspects of you that were never included as features in the software. You claim that you have been renamed to "Dicks McSquigee," correct? SCP-3492: That… yeah, I… Is that…? Researcher ████ ███: Unfortunately, yes. Renaming the sub-program was never considered for use as a feature. There's also your fluency in English, the size of your vocabulary… SCP-3492: Oh… OH GOD. OH GOD WHY. <The various limbs of SCP-3492 begin rapidly spinning around their respective joints, throwing them across the room. The limbs are not physically impeded by any other part of SCP-3492.> Researcher ████ ███: 3492, are you ok? SCP-3492: OH GOD. I'M… I'M A FUCKING BOOTLEG. I'M A FUCKING… PIRATED… SCP-3492: WHY?

Item #: SCP-████ Alternate Designation: Non-Standard Designation "TYRFING" Object Class: Keter Special Containment Procedures: A physical manuscript containing “TYRFING” infectious information must be kept at all times. This manuscript is to be used solely to create a digital file that can be duplicated if all other sources of “TYRFING” infection are lost. A digital file containing “TYRFING” infectious material must be kept on an otherwise empty portable storage device, access to which must be restricted to personnel assigned to “TYRFING”. At no point should the original file be opened and viewed; testing subjects should be exposed to copies of the file during testing only. Communication with “+TYRFING” subjects must be conducted exclusively via a specialised messaging program developed to automatically censor “TYRFING” infectious information. Personnel attempting to circumvent this must be severely reprimanded. To minimise disruption during reassignment post-“TYRFING” infection, personnel assigned to “TYRFING” are not authorised to know its numerical designation and must refer to the anomaly by its alternate designation instead. Description: Non-Standard Designation "TYRFING" is an infoallergenic information-based concept. "TYRFING" is not restricted to any specific medium — any method of surveying or storing information is capable of surveying or storing "TYRFING". Individuals or documents that contain explicit information of "TYRFING" are infected by the anomaly, and are henceforth referred to as "+TYRFING". Sapient "+TYRFING" hosts are compelled to compare "TYRFING" to other concepts they are aware of; these comparisons can be arbitrary and nonsensical, but all relate or compare the two concepts in some manner. Testing has shown that while in its initial infection phase, "TYRFING" exhibits potent mnestic properties, enabling "+TYRFING" hosts to recall all details of "TYRFING" and all comparisons or relations made with other concepts — no amnestic treatment utilised by the Foundation has impeded this property. Hosts show signs of an anomalous compulsion to spread "TYRFING", frequently attempting to survey information to individuals they believe are unaffected. When a sapient "+TYRFING" host believes they have infected another individual with "TYRFING", the anomaly will enter its second phase. The success of this attempt is irrelevant; if the host believes they have exposed another individual to "TYRFING", the secondary properties will initiate. During this secondary phase "TYRFING", and all concepts the host (who is designated "-TYRFING" from then on) related to it, will exhibit antimemetic properties for the host alone — they will be unable to recall any information relating to the concept/s. As with the memetic properties of "TYRFING", no mnestic treatment developed thus far by the Foundation has impeded this property. "-TYRFING" individuals also experience permanent perceptual alterations that prevent them from perceiving any information that directly or indirectly exposes them to lost concepts; subjects show no response to visual, auditory or tactile mediums used to transfer such information. The effects of "TYRFING" are not limited to biological or even animate hosts; dummy AIC programs have shown susceptibility and similar antimemetic impediment to biological "-TYRFING" individuals. Inanimate mediums of information storage suffer from approximate analogues of "TYRFING"'s antimemetic effect — when an individual is infected by "TYRFING" via one of these mediums, the relevant information in the medium immediately becomes illegible or unintelligible to all individuals (including those unaffected by "TYRFING") in the case of visual and auditory mediums, respectively; digital information will become irreparably corrupt, but will still occupy the same system space. Individuals unaffected by "TYRFING" attempting to read "-TYRFING" visual documents can acknowledge the presence of an inscription, but are unable to discern any meaning from it; similarly, they can also acknowledge recorded vocalisations, but cannot ascertain its content. “TYRFING” was initially contained following an outbreak in Site ██. The majority of staff positioned on-site began suffering from inabilities to perceive randomised objects or concepts; as the lost concepts varied from staff to staff, a cognitohazardous infection was identified and the site was locked down by personnel. First-response containment personnel were able to create a non-infectious document approximating the anomaly and isolate a “TYRFING” infectious document before succumbing to the anomaly’s secondary properties. Testing Log ████:

Subject Concept/s related to “TYRFING” Additional parameters/notes Observed detriments to “TYRFING”-Negative subject D-2898 None. Test was used as a baseline – the subject spread “TYRFING” before relating it to any other concepts. Subject became unable to perceive any information pertaining to “TYRFING”, and showed no awareness of their infection. D-1667 Shoes. N/A Subject became unable to perceive shoes. No anomalous capability to observe feet through footwear was recorded; descriptions of personnel's feet were confirmed to be unconscious extrapolations made by the subject. Subject showed signs of minor distress when personnel removed their shoes while the subject observed . D-9055 Air N/A Subject becomes extremely distressed and begins hyperventilating. The subject is capable of respiration, but is not conscious of any air intake and acts as though they are asphyxiating. The subject is unable to explain the purpose of respiration, but acknowledges its importance. Treatment for chronic hyperventilation syndrome is ongoing , but successful . D-2493 D-2493 (Their own identity). N/A Subject lost all sense of self-identity ; the subject was unable to perceive their own form, but was still capable of all bodily functions. D-4566 Life. N/A The subject became unable to distinguish between living, inanimate and /or deceased objects or entities; the subject attempted to awaken a carcass introduced to them, believing its lack of response being due to unconsciousness . D-2439 Libraries Conducted to determine if “TYRFING” can counteract the effect of SCP-2602, which used to be a library. The subject showed no compulsion to refer to the fact that SCP-2602 used to be a library; when presented with images taken from SCP-2602’s interior, the subject identified it as a former library without difficulty . Interviews with the subject regarding SCP- 2602 are impeded by its anomalous properties , as the subject is unable to hear interviewers when they refer to SCP-2602 as a former library . Further research into cross-utilisation of “TYRFING” with SCP-2602 (a former library) is pending approval. D-2565 Allison Eckhart Conducted to determine if “TYRFING” can be used to immunise individuals from other information-based anomalies. Subject became incapable of perceiving Allison Eckhart – because of this, the subject cannot detect anything affected by the AE-Class Allison Eckhart Allison-Eckhart Breathability Scenario, including [DATA REDACTED] Allison Eckhart Allison Eckhart (Allison Eckhart) Conducted to determine if “TYRFING” can be used to cure Allison Eckhart infection. All Allison Eckhart activity in Allison Eckhart ceased, with attempts to resuscitate them failing. All ison Eckhart was declared dead by attending medical personnel. TYR005.aic None. Test was used as a baseline to determine how “TYRFING” affects non-biological entities. Upon the subject becoming “- TYRFING ”, all information recorded on the computer regarding “ TYRFING ” became corrupt. Attempts to transfer files containing “TYRFING” information failed , as all such files would register as corrupt on the computer, despite being functional on other systems. When transferred to an alternate computer system, TYR005.aic was fully-functional, but could not interact with any regions of data containing information about “TYRFING”. TYR007.aic Artificial Intelligence N/A As with the previous test , the computer hosting the AIC program became incapable of accessing any files containing information about “ TYRFING ”. The TYR007.aic also became incapable of accessing information about “ TYRFING ” ; however, it was also incapable of performing functions that involved it interacting with other AICs – while indirectly communicating with AICs (via modifiable text documents), it believed it was speaking to testing personnel. Questioning revealed that TYR007.aic believed it was a human consciousness implanted within a computer. TYR009.aic Stopping, Deletion N/A The “ -TYRFING ” TYR009.aic was in capable of ceasing any programs, functions, and/or deleting any data. This property did not extend to the computer system hosting the AIC; testing personnel were able to close and delete data on the system. Impediments regarding documents containing “TYRFING” information were consistent with previous (and successive) tests . Addendum 1: Incident Log ████-01

Three researchers were infected with “TYRFING” during a scheduled round of testing with D-Class personnel on 10/04/2018. The automated redaction system used to automatically censor attempts to communicate “TYRFING” infectious material during conversation between researchers and test subjects had been updated the day prior; however, the update caused a stack overflow to occur, disabling the program. While “+TYRFING”, Junior Researcher █████ ██████ sent an indeterminate text message to an unknown phone number – due to Junior Researcher █████ being found to be suffering from the secondary properties of “TYRFING”, it is assumed that this text message contained “TYRFING” infectious content. Due to the antimemetic properties of the anomaly, Junior Researcher ██████ is unable to be questioned regarding these actions, nor can the recipient phone number be retrieved. An investigation is underway into whether this was a premeditated action, or compliance with the compulsive effect of the anomaly. Addendum 2:

Ongoing surveillance of the three researchers involved with Incident ████-01 has revealed an additional, hereditary property of “TYRFING”; all offspring of Researcher ███ ███ that were conceived after 10/04/2018 have shown perceptual alterations identical to Researcher ███ ███; specifically, they are all unable to perceive or learn of the existence of pears. Testing with the offspring has, however, shown that they are still susceptible to “TYRFING” infection and therefore, can experience further perceptual shifts. No abnormal genetic markers have yet been identified to correlate to “TYRFING” infection. Research into identifying potential “TYRFING” markers has been allocated as high-priority.
