Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Due to the location of SCP-XXXX, it is extremely unlikely that civilians will ever encounter it. Regardless, Foundation personnel embedded within government organizations involved with the exploration and examination of space, and especially the moon must be constantly vigilant for any mention of a sighting. In the case of a sighting, Foundation personnel are to give those involved with a sighting a Class-B amnestic with a dose high enough to remove any memory of the sighting. After this, all data on that day is to be scrubbed and replaced with information that depicts the site of SCP-XXXX as uninteresting and not meriting further research.
As for containing SCP-XXXX, absolutely no personnel are allowed to enter into XXXX. without clearance of at least two 05-class personnel. Any personnel attempting to do so will be considered dead and no recovery will be attempted. XXXX is to be entered ONLY by unmanned remote drones with a wireless camera attached. These drones must not be returned except under collection of samples of SCP-XXXX-3, and the recordings are to be saved wirelessly to a storage drive. Any samples of SCP-XXXX-3 are to be contained in a nine cubic meter, vacuum-sealed, lead chamber with an interior lining of Uranium-235 at least 1cm thick, suspended over SCP-XXXX and kept in an ultrasonic field of such strength that the sample cannot come into contact with any of the walls. This field should be monitored constantly by at least one Class-D personnel for any deviations in the containment field. Should a sample of SCP-XXXX-3 come into contact with the containment cell, or any other matter, the uranium lining is to be analyzed, and depending on the severity of the damage to the lining, will either be replaced in the case of low breach risk, or if a breach is observed to be imminent, the entire chamber is to be dropped back into SCP-XXXX.
In case of an irreversable containment breach, see adendum XXXX-A.
Description: SCP-XXXX is a 12 meter by 8.5 meter pool located in the [█████] on the [█████] hemisphere of the Earth's moon. SCP-XXXX contains a highly dense semi-liquid that is currently unidentifiable and has been classified as SCP-XXXX-1. SCP-XXXX-1 is non-radioactive and non-reactive. It resembles mercury in appearance, albeit with a copper shading in place of the silver coloration of mercury. Upon an object entering SCP-XXXX, it will rapidly sink into SCP-XXXX-1 only to emerge on the other side of SCP-XXXX, a dimension referred to as SCP-XXXX-2.
SCP-XXXX-2 is a near perfect mirror of our own reality with a few exceptions. From surveillance of the area via drone, the Earth is visible and is covered in an unknown organism, classified as SCP-XXXX-3. The same organism can be observed in various locations on the surface of this dimension's moon. Samples gathered from the moon's surface have discovered that any trace of water, even on a molecular level, cannot be found. Upon applying 10 cL of water via drone to the soil, the sample was observed moving towards the nearest sample of SCP-XXXX-3. When the water reached the sample of XXXX-3, it was absorbed and the sample of XXXX-3 grew by 2.3 milimeters in 1.39 seconds.
SCP-XXXX-3 appears to have evolved from a common brain coral native to the Great Barrier Reef as a result of rising ocean acidities. XXXX-3 has evolved to be environmentally hardy enough to withstand the extremes of space, and the ability to gather necessary nutrition from a wider range of sources. It is unknown whether XXXX-3 is a singular entity or instead a community of organisms as its shape would suggest. XXXX-3 has not shown any signs of cellular death, yet can only grow when in contact with water and another molecule. So far, tests have found that XXXX-3 can safely ingest every element on the known periodic table provided it also has water to assist in the process. Certain elements appear to take longer to digest, but the longest digestion time from testing has been a gram of Uranium-235, which was completely consumed in 21.25 hours. Deionized water does not appear to have any effect on this process. The current hypothesis is that the organism is capable of breaking any matter it comes into contact with into its base elements, which it then is able to assimilate into itself with the use of the hydrogen and oxygen atoms found within water. Whether it actively reshapes the digested atoms into another form of matter or simply assimilates it is currently unknown and awaiting clearance for further research.
Though XXXX-3 likely originated on earth, it has been observed to bridge the gap between the two celestial bodies with the usage of long strands of XXXX-3. These strands are roughly 10 meters in radius, and are connected to one another by thousands of smaller strands. This structure has also been observed to catch various pieces of debris which is then absorbed into the larger mass, leading researchers to hypothesize that this is one of the ways in which SCP-XXXX-3 has managed to grow as extensively as it has, feeding off passing extraterrestrial bodies that are ensnared in the strands. Comets would be especially useful, as the ice would be a useful source of hydrogen and oxygen to allow further growth of the SCP.
As a result of a structural collapse on the edge of the crater within SCP-XXXX-2, drone footage was able to capture a recording of a sample of SCP-XXXX-3 becoming isolated from the rest of the mass. At this point, it appeared to harden, and enter a static state. The drone then applied 0.5 cL of deionized water to the soil, which the isolated sample absorbed, before growing a series of small tendrils like those observed between the earth in SCP-XXXX-2 and the moon. These tendrils reached out towards the rest of SCP-XXXX-3, and upon making contact with the main mass, reinforced the connection, allowing the once isolated sample to be reconnected with the rest of the SCP. Additionally, when it is not actively growing, it returns to this hardened state, most likely to conserve energy. However, as noted during Addendum SCP-XXXX-B, it is aware of any matter that it could potentially consume within 10 meters of itself, regardless of any obstacles between the matter and the SCP. The current method with which it does this is unknown, though researchers have hypothesized that the SCP may have some sort of sensitivity to the electric charges within and between various atoms, even in the case of neutrally charged atoms.
Under no circumstances can SCP-XXXX-3 be allowed to come into contact with a self replicating scp such as SCP-682.
Addendum SCP-XXXX-A: The Final Eclipse Procedure
Given the nature of SCP-XXXX-3 and its asimilative abilities, it must be treated with the utmost caution and, should it breach containment and it becomes impossible to return it to SCP-XXXX, it must be treated as a NK-Class "Grey Goo" Scenario. In this case, foundation personnel are to put all available resources into neutralizing SCP-XXXX-3. Should these attempts prove ineffective, SCP-XXXX-A is to be enacted, in which foundation personnel are to activate a warhead within the moon's surface. This warhead is to be powerful enough that, should it be detonated, the moon will be dislodged from the earth's orbit and thrown into space, ideally either towards a distant star or a black hole. This is liable to cause immense damage due to tidal shifts and other natural disasters as a result, but is necessary to ensure the safety of mankind. As such, this procedure requires the clearance of all 05 personnel, and will require extensive coverup by the foundation, using the cover story that the explosion was the result of a previously undetected celestial body colliding with the moon.
Addendum SCP-XXXX-B Recording of Incident XXXX-C
█████: 22 year old, caucasian male. Height: 6'0" Weight: 201 lbs. Astronaut with the █████ program.
Interviewer: [Dr. █████]
Foreword: Incident XXXX-C was the result of the first and last human exploration of SCP-XXXX-2. █████, a 22 year old, caucasian male fell into SCP-XXXX after a mission to attach an array of sensors to a previously unexplored crater on the moon. Before falling, █████ reported feeling seismic activity, after which the ground gave way. Video and audio feed begin after █████ emerges from the other side of XXXX
<Begin Log>
As the video feed goes live, all that is visible is the dark wall of a lunar cavern
Dr. █████: █████, do you read me? Repeat, do you read me?█████: Yeah doc, I can hear you…
Dr. █████: Good, your video feed seems to have maintained connection. Could you turn on your light?
█████: Sure, one sec.
A few moments later, █████'s light illuminates the cavern, with a cursory glance revealing a tunnel in one of the walls.
Dr. █████: █████ we cannot locate you on our instruments, please find a way to the surface and we'll send a rover to pick you up.
█████: Got it.
█████ proceeds down the tunnel, humming softly to himself before stopping.
Dr. █████: █████, is something wrong?
█████: The soil feels all wrong. It's like walking on fresh powder. I just kind of sink into it.
Dr. █████: Please retrieve a sample.
Video shows █████ bending over to scoop up a small sample of the soil into a collection vial. When camera resumes previous angle, a spot of natural lighting is now visible ahead.
█████: Huh, that cave-in must have caused this to open up.
Upon approach, █████ appears to be correct, arriving at a cave-in, leading to an opening in the tunnel roof that leads to the moon's surface. Upon emerging from the tunnel, █████ lets out a yell of suprise.
Dr. █████: █████, what is it, we can't see anything from this angle.
█████ tilts the camera upwards to show what was once earth, though at time of recording this was not clear. The pacific and Atlantic oceans appear much smaller, and instead of their natural blue appear a very pale yellow akin to that of hydrochloric acid. Long strands of XXXX-3 can be seen connecting the earth to the moon, with an anchor point within one kilometer. There is a minute of silence before audio resumes.
Dr. █████: █████, we need you to gather a sample of whatever that thing is. The anchor point should only take 15 minutes to get to, leaving you with plenty of oxygen for a return trip.
█████: Understood.
Camera bobs slightly as █████ begins the trek to the nearest anchor point, a trip that takes a total of 14 minutes and 23 seconds. Occasionally █████ turned to look behind him, and the camera records a long trail of footprints in the soil. When █████, he withdraws another collection vial from his belt and uses a small scalpel to collect a sample of XXXX-3. XXXX-3 does not appear to react.
Dr. █████ Alright █████, please return to the pool, we're working on how we're going to get you back home.
█████: Got it doc… This place creeps me out.
Video shows █████ following the trail of footprints back in the direction he came. After twenty minutes, the footprints vanish all together.
█████: What in the… Where's the opening?
Dr. █████: █████, did you get lost?
█████: No! I've been following my footprints the whole time, and now they're just… Just gone!
The camera bends down to look at the suddenly vanished footprints, and only █████'s heavy breathing can be heard.
Dr. █████: █████, you need to calm down. You're going to use up your oxygen too quickly if you don't.
█████ does not reply.
Dr. █████: █████? Do you read me? █████?
█████ does not respond, but the video shows a collection vial floating by, with a hole melted into the container. Audio is suddenly cut off by the sound of explosive decompression, followed by complete communication loss.
<End Log>Closing Statement: This incident brought SCP-XXXX to the foundation's attention, and led to the approval of several unmanned drone exploration missions. The original mission was covered up by embedded foundation personnel with the cover story of it instead being a failed satellite test. Non-foundation personnel that assisted in the launch were given class-B amnestic and given the same cover story. Additionally, given the nature of █████'s death, Foundation researchers have classified XXXX-3 as having above-average intelligence, capable of waiting for an opportune moment to feed, and luring its prey into trap. The limit of its intelligence is currently unknown and awaiting further research.
