Item #: SCP-2542

Object Class: Euclid

Special Containment Procedures: SCP-2542 is to remain contained in a 7m by 7m, containment facility with a one way mirror on the side facing SCP-2542's entrance.Despite no history of moving, SCP-2542 needs 24/7 supervision. When testing or routine inspections take place, it is advised to not step foot inside of SCP-2542 due to the November 9th incident. If interior inspection is imperative, SCP-2542's entrance must be secured by multiple MTF guards to keep from closing magnetic force used to pull the door as far open as it can be opened.

Clearance has increased from Level-0 to Level-2 due to past events involving SCP-2542. SCP-2542 has been known to exhibit unpredictable behavior over the course of its containment. Extreme caution is to be exercised when in close proximity to SCP-2542. Magnetic substances are not allowed inside the containment area. The only instances in which metallic substances are allowed within the containment facility is during crucial testing requiring level 3 clearance and higher. If any personnel are careless enough to break this rule, they will be suspended from their duties for an undisclosed amount of time and incarcerated until SCP-2542 staff permits them to resume their duties.

No testing on SCP-2542 is to occur without clearance and the approval of the SCP-2542 project director.

Description: SCP-2542 is a 3m by 3m single prison cell made of Iron walls which measure 33 cm in thickness. One defining visual characteristic is the number '62' painted on the right side in white. SCP-2542 has been proven to exhibit sentient traits as well as the ability to learn and evolve its anomalies. SCP-2542 has control of its internal pressurization levels. When exercising this anomaly, it lowers the pressure inside from a normal level to fatal levels. (It is the equivalent of the pressure of multiple atmospheres condensing down into one.) This yields similar results as explosive decompression. Victims, depending on their proximity to the source of the pressure change are immediately, and violently dismembered. Internal organs are ejected from the body, limbs are ripped out of their sockets, and the state of the body is turned into an innumerable amount of fragments and pieces.

SCP-2542 has the power of pressure variation, otherwise known as 'DELTA P' once its door is sealed. There have been no findings of man-made devices causing these results. According to the recently installed barometer, the PSI within SCP-2542 is the same as the outside pressure until the door is sealed. If there is no test subject inside, the pressure maintains a normal level. However, if there is a test subject inside, the pressure decreases past the point of accurate readings from the barometer.

SCP-2542 has been known to exhibit sentient behavior over the course of its containment. Its evolution of sentience is unpredictable. New abilities have appeared in various lengths of time ranging from two weeks after its previously acquired mode of power to seven months. Many evolved abilities have been minor in significance, although multiple dangerous developments have taken place as well.

Some observed examples of minor change are:

Writing on the outside walls of 2542 which can range in language or simply be unintelligible

Low, robotic-like, unintelligible voices emanating from 2542. No coherent sentences have been recorded, but random words and numbers have been heard coming from 2542. Although there hasn't been any direct correlation with the words spoken by 2542, the majority have been spoken in Latin and Russian.

Changes in the temperature of the of 2542's iron. The temperature in the facility remains at 16 degrees Celsius at all times, but 2542's walls have been recorded being between a range of temperatures. The lowest recorded was -12 degrees Celsius, and the highest being 23 degrees Celsius.

Differences in the texture and appearance of the iron. This includes, massive dents, color change, and a rare phenomenon of puncture holes all the way through the iron. However, this has not effected the pressure levels inside.

Addendum:SCP-2542 has acquired illusionist tactics such as having lost items from Foundation personnel appear inside, luring those careless enough to their deaths. Previous tests of SCP-2542's illusion ability used stray dogs and feral cats as test subjects to observe the effects on different subjects besides D Class personnel. All subjects were terminated by explosive force of various strengths.

Notably, SCP-2542 becomes agitated and harder to control when inmates are brought within its proximity. SCP-2542 uses its illusion ability to attempt to lure the inmates near. If the inmates are not persuaded by the illusions, this causes SCP-2542 to emit a high frequency pitch as a response.

(SCP-2542 will emit a high frequency pitch when being subdued by the magnetic force used to combat its attempts to close its door, which has proven successful in restraining SCP-2542. Two possible theories for this reaction have been taken into consideration. One being that the high pitch is its response to pain and the equivalent of crying to a human, or possibly a tantrum similar to those observed in young children.)

One instance which had involved prisoners, SCP-2542's research team and MTF guards had been equipped with ear protection and were not affected by the high frequency pitch. The inmates involved in the test however, were unequipped with said protection, and became unresponsive due to massive strain on the inner ear and brain. One prisoner dropped dead on site. Later autopsy showed that the inmate had suffered an aneurysm of the brain. The surviving inmates in the test were subsequently forced into SCP-2542.

SCP-2542 seemed to become more cooperative after the prisoners were terminated. This introduced the theory that SCP-2542 is able to detect who is and who is not a threat or an individual who it deems not deserving of life based on their past or present actions. No details on if it is able to detect an individual's future actions at this time. Current research is studying this theory.

+ Recovery of SCP-2542 - Recovery of SCP-2542 Recovery: Holding Cell 62 was found with the aid of the United States Department of Defense. In February of 1992, the Foundation was contacted by General ██████ about a possible WMD discovered by Special Forces in the North Korean city of ████████████ with the aid of defecting North Korean scientists. According to the defectors, Holding Cell 62 was loaded onto a flatbed truck for transportation to the Chinese city of Dalian. It had been speculated that North Korea was to give the Governments of ███████ and ███████ the rights to weaponize 2542. The truck lost control and became partially submerged in the ███████ river when Holding Cell 62 emitted a strong magnetic burst. The now defected scientists were among the convoy that was aiding the truck in its transportation mission. Although they had not seen the anomaly with their own eyes, they had only previously been aware of the extreme pressure variation aspect. They had not been aware of the magnetic burst evolution until that moment. They had previously speculated that 2542 rather than having many abilities and harboring them until needed, SCP-2542 had developed this ability over a period of time. They had, only then seen the power of SCP-2542 after an unaware Korean soldier opened SCP-2542 and became trapped inside until falling victim to explosive decompression. After managing to pry the door open, what was once the soldier had been described as "unrecognizable piles of liquefied meat". The scientists managed to slip away after another magnetic pulse was emitted from SCP-2542, causing the closest vehicles to the truck to be crushed and mangled. The scientist's vehicle was spared from heavy damage due to the car in front of theirs taking the brunt of the impact. After the scientists made contact with American forces at the DMZ, they were taken in for questioning. They released all information about SCP-2542 over to the American forces and lead them to the crash site. The U.S. forces transported SCP-2542 via multiple helicopters to the USS █████ for transport back to the U.S. which was carried out without incident. Once SCP-2542 was contained by the foundation, Dr. Ryker who had been one of the first notified personnel and who had aided in the recovery of SCP-2542 began research along with the scientists. Since 1992, there have been major developments regarding SCP-2542. For the most part, SCP-2542 has complied with our Foundation as if it understands the Foundation has no interest in using it for destruction. Every instance of major hostility apart from minor occurrences has been exercised on perceived hostile humans such as November 9th. Around the time of 2542's recovery, the North Korean defectors only referred to 2542 as a "Potential Weapon of Great Threat". At the time, foundation staff could not confirm these claims, until learning of its evolutionary traits. The countries that were to receive 2452 refused to comment when asked what their intended use for 2452 was. Through years of governmental aid and eye witness accounts, the Foundation has concluded that 2542 was to be used against the U.S. in the Middle East by the allies of the supposed countries who were to receive 2542.

+ November 9th incident - November 9th incident On November 9th, 1999, three recently transferred researchers from ██████ and █████ were lured inside of SCP-2542 by using a 'missing folder' that contained important research compiled at the Foundation site they had transferred from. The three researchers, and Mr. Park, a previous colleague of the Korean scientists who discovered SCP-2542, entered SCP-2542 at 11:48 A.M under the pretense that the door was secured by MTF guards. 5 minutes passed between the closing of the door and the end of the incident. It was speculated that SCP-2542 focused its pressure forces on each separate occupant one at a time. Despite no scientific possibility of selective pressure being implemented, it seems that 2542 had somehow defied physics and created the only recorded event of selective pressure. One of the researchers from ██████ was first to fall victim to SCP-2542. Approximately 2 minutes after the sealing of the door, his chest burst from the inside leaving a gaping hole through the chest cavity. The second researcher from ██████ had his left arm blown from the socket. This sent out bone fragments which struck the jugular of the researcher from █████ and had also sent fragments into vital internal organs of his own. Two MTF soldiers who were assisting in the securing of the door were shoved inside when SCP-2542 slammed the door crushing the legs of one guard, and severing the fingers on the left hand of the other MTF guard. These were seen as accidental casualties due to no further damage inflicted on them. Mr. Park had received a lesser amount of decompression, but enough to leave his left side in a post-stroke like state. Mr. Park has been under surveillance since the November 9th incident, and has shown no signs of recovery; However, an increase in blood iron levels is apparent in Mr. Park. The reasoning behind SCP-2542's behavior that day is uncertain, but it is believed there is a correlation to the nationalities of the victims in the failed transport of 1992, and the victims of November 9th. The three researchers were of the same nationalities as the countries that North Korea planned to give rights to weaponize SCP-2542 to. Mr. Park, was a North Korean expat, the same as the defected scientists. The only hole in said theory is the defector scientists were not targeted by SCP-2542, but the foundation has still considered moving them to Class A status as precaution. This offer was later denied by the scientists.
