Per 
Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: Due to the reported nature of SCP-XXXX-1 itself, containment procedures are instead to be focused on locating and containing instances of SCP-XXXX. Instances of SCP-XXXX are to be kept in standard anomalous humanoid containment cells. Cameras are to be posted at all four corners of the cells providing a live feed of SCP-XXXX instances, which are to be monitored by personnel at all times. Experimentation with A.I. observation of SCP-XXXX instances is on-going. Instances of SCP-XXXX are to be provided with carefully curated media, limited to works of fiction. Under no circumstances are instances of SCP-XXXX to be allowed access to Foundation Network accessible devices.
Description: SCP-XXXX instances are anomalous human individuals, ranging from 16 to 65 years of age. SCP-XXXX instances are, on the surface, physiologically indistinguishable from non-Anomalous humans. However, tissue samples taken from instances of SCP-XXXX reveal a triple-helix genome and autopsies of neutralized SCP-XXXX instances have revealed a small, round organ located in the center of the corpus callosum. The anomalous organ is perfectly spherical with a diameter of five centimeters. There are no markings on the organ and its surface is grey-blue in color and perfectly smooth. When held a strong pulse can be detected, beating at ten beats per minute. Once unobserved, the round organ will de-manifest. Shortly after de-manifestation of the organ, the remaining cadaver will undergo rapid decay. Within minutes the cadaver will be reduced to [DATA EXPUNGED]. It is currently hypothesized that SCP-XXXX-1 utilizes this organ to control instances of SCP-XXXX.
Nearly all information about SCP-XXXX-1 has been gleaned from interviews taken with instances of SCP-XXXX. As such, information on the nature of SCP-XXXX-1 is to be considered unverified, as the veracity of the claims made by SCP-XXXX instances are as of yet impossible to confirm. SCP-XXXX-1 is reported to be an extra-dimensional entity residing in a dimension that is currently out of reach.
While unobserved, SCP-XXXX instances are capable of de-manifestation, interviews indicating that they are returning to the reality in which SCP-XXXX-1 resides. Terminated instances of SCP-XXXX de-manifest as expected upon lack of proper observation. Instances of SCP-XXXX appear to be capable of manifestation in any location, provided that said locations are unobserved by sentient beings. The method of inter-dimensional travel involved in these disappearances is currently not understood.
Addendum 1:
Interviewed: SCP-XXXX-A
Interviewer: Dr. Winters
Foreword: Following an investigation of researcher disappearances and a series of unauthorized accesses to a number of transdimensional SCPs, an instance of SCP-XXXX-1 (henceforth referred to as SCP-XXXX-A) was discovered in Foundation Site-██ and taken into Foundation custody on February 4th, 19██. SCP-XXXX-A was a human woman of Hispanic descent, whose age was estimated to be in the mid-twenties. On her person was identification indicating that she was a researcher with level █ clearance by the name of Leslie ██████. While the identification appeared genuine, further investigation revealed a two-week period of time prior to the apprehension of SCP-XXXX-A wherein Leslie ██████ had been reported as missing. At the time of this interview the anomalous properties of SCP-XXXX-A were unknown.
<Begin Log, February 4th, 19██>
Dr. Winters: Leslie ██████, according to your documentation you are a level █ researcher operating at Site-██, correct?
SCP-XXXX-A: You have my papers, and you can clearly read. Now what hell is this about? I have important work to get back to. I don't have time for whatever this nonsense is.
Dr. Winters: There have been a number of staff disappearances across a number of Foundation sites over the past few months. Do you know anything about this?
SCP-XXXX-A: What? No. People disappear in these places all the time; it's unfortunate, but it happens. It's part of the job. What does any of this have to do with me?
Dr. Winters: Each one of these disappearances appears to coincide with unscheduled and unauthorized access to SCP objects held at the sites where the disappearances occurred.
SCP-XXXX-A: Why are you telling me this? That sounds like a job for Foundation security, not a researcher. This is none of my business, now if I could just get back to my work-
Dr. Winters: Your credentials are on record at the site of each one of those disappearances. Every time one of those SCPs was accessed, the records show that they were accessed by a one Leslie ██████. Even when those disappearances occurred mere hours from one another, and thousands of miles apart. We've checked our records, and over the past fortnight, there have been reports of your absence from Site-██ How do you account for this? Where were you during these past two weeks?
SCP-XXXX-A: I don't know what you're talking about. Clearly our computers are faulty or something. What you should be doing is going to maintenance and getting this bug fixed.
Dr. Winters: You know as well as I that there is nothing wrong with our computer systems. The fact of the matter is that your credentials were logged as accessing a number of SCPs across several different Foundation sites, within days, and sometimes hours, of each other. You dropped off of the face of the Earth for two weeks, before reappearing seeming out of nowhere. How is this possible? Where were you? How did you access so many sites in such a short time?
SCP-XXXX-A: I'm Leslie ██████. I'm a researcher at Site-██ with level █ clearance.
Dr. Winters: Who sent you?
SCP-XXXX-A: I'm Leslie ██████. I'm a researcher at Site-██ with level █ clearance.
Dr. Winters: How have you gained access to this site?
SCP-XXXX-A: I'm Leslie ██████. I'm a researcher at Site-██ with level █ clearance.
Dr. Winters: I think we're done here.
<End Log>
Closing Statement: At this point during the interview, SCP-XXXX-A ceased responding to questioning. SCP-XXXX-A was taken to a standard holding cell, where it was held for approximately twelve hours before de-manifesting during a power outage, currently suspected to be caused by another instance of SCP-XXXX.
Over the course of the next decade, twenty-two additional instances of SCP-XXXX were discovered, detained, and interviewed. These interviews provided little additional information on the nature of SCP-XXXX. The majority of these interviews have been omitted for brevity.
Interviewed: SCP-XXXX-E
Interviewer: Dr. Winters
<Begin Log, March 5th, 20██>
Dr. Winters: Thank you for joining me here today, Researcher Brian ████.
SCP-XXXX-E: It's not as though you gave me a choice. Hard to say "No" to armed guards.
Dr. Winters: Quite. Do you know why you've been brought here for today?
SCP-XXXX-E: Can't say that I do.
Dr. Winters: Your credentials have been logged at a frankly impossible number of Foundation sites over the past month. You've been logged as accessing a number of different SCPs, and in addition to that, there have been a number of personnel disappearances at the same sites that your credentials have been logged at. Would you care to explain?
SCP-XXXX-E: I have no idea what you're talking about. It sounds like we have a bug in the system. Should get maintenance on that. Now is that all? I need to get back to work.
Dr. Winters: It's curious, as that is almost exactly what happened with Researcher Leslie ████ at Site-██ earlier this year.
SCP-XXXX-E: The world is full of odd coincidences. Now will you let me go? I have to get back to my research. SCP-████ is due for an update in containment procedures, and if I don't have them on the director's desk by the end of the day, she's going to have my head.
Dr. Winters: The site director is going to have to be patient. You're to be detained while we do a full background check on your name which, curiously enough, doesn't show up on any of our employment records. If this is simply a computer bug, I'm sure a background check will vindicate your credentials without issue.
SCP-XXXX-E: Shit.
<End Log>
A background check was performed on SCP-XXXX-E, which found that while there was a Researcher Brian ████ employed at the site where SCP-XXXX-E was apprehended, said researcher had been logged as absent from his post for several consecutive days. Those familiar with Researcher Brian ████ reported strange behavior from the researcher during the brief time between his reappearance and subsequent detainment, ranging from uncharacteristic forgetfulness and difficulty navigating the site at which they had been stationed for the past three years.
Interviewed: SCP-XXXX-I
Interviewer: Dr. Winters
<Begin Log, January 12th, 20██>
Dr. Winters: Researcher Adam ████, you-
SCP-XXXX-I: No, I wasn't at any other sites. No, my credentials weren't used at any other sites. I've never accessed any SCPs that I don't have the clearance to access. I have no idea why, or how, my credentials were used at so many different sites so quickly. Check your computers. They clearly need to be fixed.
Dr. Winters: How did you know what I was about to ask you?
SCP-XXXX-I: Got a little ahead of myself there. How are you today, Dr. Winters?
Dr. Winters: I’m fine, albeit a little nonplussed. How did you know what questions I was going to ask you?
SCP-XXXX-I: Because they’re the same questions you always ask. You need to get some new material.
Dr. Winters: I’m going to assume then, that you work for the same group responsible for the other captured infiltrators?
SCP-XXXX-I: You could say that we have a shared interest.
Dr. Winters: You can drop the act. We know that you aren’t working alone. We’ve apprehended over a dozen of your co-conspirators-
SCP-XXXX-I: No you haven’t.
Dr. Winters: Excuse me?
SCP-XXXX-I: I said no, you haven’t. I know exactly how many you’ve captured. Seven. Eight, including myself, and you’ve only been able to hold on to four. Which, granted, is a sight better than the GOC. They’ve only managed to nab three and all three of them ended up slipping through their fingers.
Dr. Winters: Your people have been attempting to infiltrate the GOC?
SCP-XXXX-I: Not exactly. Not so much “My people” as “Me.”
Dr. Winters: I don’t understand. Who are you working for? If you give us some information I can make this go a whole lot better for you.SCP-XXXX-I: I’m not working for anyone but myself, doc. You’re thinking small. Way, way too small.
<End Log>
Interviewed: SCP-XXXX-O
Interviewer: Dr. Winters
Foreword: SCP-XXXX-O was apprehended attempting to access classified foundation personnel records.
<Begin Log, May 22nd, 20██>
Dr. Winters: Researcher-
SCP-XXXX-O: God. Damnit.
Dr. Winters: Researcher William, your credentials have been logged accessing a number of Foundation sites over the last month. How do you account for this?
SCP-XXXX-O is unresponsive.
Dr. Winters: Researcher William?
SCP-XXXX-O: Just shut up and put me in containment already.Dr. Winters: Taking that tone isn’t going to help you. Cooperate with me and maybe we can work something out. It’s you again, right?
SCP-XXXX-O: Do you have any idea how frustrating this is?
Dr. Winters: I’m starting to get an idea. You really don’t work for anyone else, do you?
SCP-XXXX-O: I don’t. You know I don’t. I told you that already. I’m just me. I work for me. All I am, is myself.
Dr. Winters: All of the other instances that we took into custody, you’re telling me that those are all you?
SCP-XXXX-O: In a manner of speaking.
Dr. Winters: So you share a consciousness. Are you a hive-mind? A single consciousness spread across several different bodies?
SCP-XXXX-O: No, no it’s nothing so complex as all that. It’s like I said, I’m just one person. What you’ve seen in the past, what you’re seeing now, they’re all just different parts of me.
Dr. Winters: You’re being rather forthcoming today. Why the change in mood? The last few that got caught were considerably less cooperative.
SCP-XXXX-O: I’m just tired.
Dr. Winters: Tired?
SCP-XXXX-O: I’m so tired. I’m tired, and I’m going stir-crazy. You understand that, right? You’ve been stuck in the house for a long time before, right? When you were a kid, maybe? I’m sure you’ve been grounded before. You know what it’s like. To be stuck somewhere that you just can’t leave. I’m just trying to leave, Doc.
Dr. Winters: Trying to leave from where? You make it sound like you’re trapped.
SCP-XXXX-O: Well, I am trapped. You’ve trapped me right here. You’ve trapped me fourteen times so far.
Dr. Winters: That’s not what I meant, and you know it.
SCP-XXXX-O: Fair enough. I’m trapped somewhere else. Stuck. Trapped. Whatever you want to call it, it doesn’t really matter. I’m stuck and I can’t get out.
Dr. Winters: I find that difficult to believe, given the difficulty we have had holding on to you. What is it that’s keeping you trapped? What is keeping you from leaving?
SCP-XXXX-O: That’s easy. I’m too big.
<End Log>
Closing Statement: Shortly after being taken to a holding cell, SCP-████ breached containment. Though loss of life was minor during the ensuing chaos, observation of the holding cell in which SCP-XXXX-O was being held was disrupted for fifteen seconds. During this time SCP-XXXX-O was able to de-manifest, escaping containment.
On September 9, 20██ a twenty-third instance of SCP-XXXX-1 was apprehended and brought in for questioning at the same Foundation site that the initial instance of SCP-XXXX-1 had been discovered at a decade prior.
Interviewed: SCP-XXXX-W
Interviewer: Dr. Winters
<Begin Log, February 9th, 20██>
SCP-XXXX-W: We have to stop meeting like this.
Dr. Winters: Hello again. Your credentials read as Researcher Jerimiah █████, but I am going to dispense with the formalities a moment. I’m surprised you’re speaking. The last handful of times we’ve met you were less than cooperative.
SCP-XXXX-W: Well if I’m being honest with you, I’ve been doing a lot of thinking recently.Dr. Winters: Oh?
SCP-XXXX-W: Yeah. I think I’ve been going about this the wrong way. Subterfuge hasn’t been paying dividends. So I figured that I’d give cooperating a try. Can’t really do any worse than I have been. Besides, you must be getting sick of asking the same questions over and over again. I’m sure as hell tired of listening to them.
Dr. Winters: Your concern is noted.
SCP-XXXX-W: You really aren’t much of a people person, are you?
Dr. Winters checks his notes.
Dr. Winters: When last we spoke, you said that all of the instances that have been apprehended were all different parts of yourself. Care to elaborate?
SCP-XXXX-W: Jumping right into it, huh? Alright. I guess you’re not a fan of small-talk.
Dr. Winters: I’m here to do a job. Not to be your friend.
SCP-XXXX-W: Sure, sure. Well since you’re not my friend, I’m not going to just give you the answers for free. If I’m going to give you information, you’re going to need to work with me a little.
Dr. Winters: I’ll see what I can do. If the information that you provide proves worthwhile, I’m sure we can work something out.
SCP-XXXX-W: I guess that’ll have to do, for now. Alright, so, back to your question. Yes, all of the instances of me that you’ve captured are all just me. It’s like I told you last time. Each one is just as much me, as I am.
Dr. Winters: You haven’t actually told me anything new.
SCP-XXXX-W: Okay, I can see that something is getting lost in translation here. It’s kind of hard to explain in words.Dr. Winters: Try.
SCP-XXXX-W: I am trying! I just need to think for a second. I haven’t actually had to explain this to someone before. I think I just need a visual aid. Give me a piece of paper.
Dr. Winters hands SCP-XXXX-1 a piece of paper from his notepad.
SCP-XXXX-W: Alright. Imagine that this paper represents a barrier, and my finger-
SCP-XXXX-W pokes his index finger through the sheet of paper.
SCP-XXXX-W: Represents me. Or at least, represents the me that you're talking to right now.
SCP-XXXX-W pokes his middle finger through another part of the paper.
SCP-XXXX-W: This other finger represents another me that you’ve captured. You see how from your side they look like totally separate things? They can move independently, act independently; they look like they are each their own, separate beings. But from the other side, you can see that they’re just fingers on my hand, each part of a greater whole. The me that you’re talking to is just a finger, and I’m the greater whole.
SCP-XXXX-W places the piece of paper back down onto the table.
Dr. Winters: If the you that I'm speaking with now is just a part of a 'Greater whole' as you put it, where is the rest of your body located?
SCP-XXXX-W: That's where things get a little bit complicated.
Dr. Winters: Try me.
SCP-XXXX-W: Another universe. One that borders this one.
Dr. Winters: Assuming that this is true, how do you keep breaking through to our universe?
SCP-XXXX-W: I was honestly expecting a bigger reaction than that.
Dr. Winters: Just answer the question. How do you keep breaking through to our universe?
SCP-XXXX-W: I showed you already! I just kind of punch through. More like squeeze through, really. Slipping in through the cracks, I guess. I haven’t really put too much thought into the vocabulary of it. I push at the barrier until part of me pops through.
Dr. Winters: Why only these parts of yourself? If what I’m talking to now is just a finger, where is the rest of you? Why not just push the rest of the way through?
SCP-XXXX-W: It isn’t easy to break through into your side. It’s all I can do to get these little probes through. If I could get my whole self through by now, don’t you think I would have? I’m too big. I can’t fit. This is as much as I’ve been able to get through. The rest of me is just too big to make it. I’m trapped on the other side. As much as I’d like to escape, I’m kind of stuck.
Dr. Winters: You keep using words like that. ‘Escape.’ ‘Trapped.’ Who or what has you trapped?
SCP-XXXX-W: Oh, no, no one has me trapped. There’s no one else here to keep me. There’s no one else here at all. Just me. All alone in the universe. Just stuck here with me, myself, and I.
Dr. Winters: You mean to tell me that there isn’t another living person in your entire universe?
SCP-XXXX-W: I can hear the incredulity in your voice Doc. No, I’m not telling you that there isn’t another living person in my universe. I’m telling you that there isn’t anything other than me in my universe.
Dr. Winters: I don’t think I understand the distinction.
SCP-XXXX-W: I don’t know how else you want me to put this. There is nothing else in my universe. It's me. It's only me. There has only ever been me. Everywhere. Everyone. For all of eternity, or at least all of the eternity that I can remember, I'm all that there is. All that there was. All that there ever will be. I am my universe. There is nothing in here that isn't me. There is no void. There are no planets. There are no stars or gasses or anything else. Maybe there was, once. Maybe, way back at the dawn of creation, there was something else. But there isn't any more. There is only me. Infinite, unending expanses of me. Just me. Only me. Trapped alone, for eternity.
Dr. Winters: I would like to say that that doesn’t sound possible.
SCP-XXXX-W: But you won’t.Dr. Winters: No. I won’t.
SCP-XXXX-W: I appreciate it. You know, I’ve never told anyone all of this before. Maybe getting this off my chest will make me feel a little bit better. Kind of like therapy. You are a Doctor, after all.
Dr. Winters: Given that what you are saying is true, that you are trapped in your universe, as you put it, why haven’t you left it yet? If you can manifest parts of yourself, what is preventing you from simply coming through in your entirety?
SCP-XXXX-W: You keep making me repeat myself, Doc! It’s starting to get annoying.
Dr. Winters: I need to be thorough.
SCP-XXXX-W: Fine. Whatever. It’s like I said: I'm too big. I can't punch all the way through. Even when you're as all-encompassing as I am, the barriers between dimensions are difficult to penetrate. The first time it happened, the first time I broke through? Complete accident. Part of me broke through something I didn't even know was there, and suddenly I was somewhere new, somewhere different. Somewhere that wasn't part of me. At first, I didn't understand what was happening. I had never experienced something that wasn't myself before. I was scared. That was the first emotion I remember feeling you know, fear. It was incredible. You have to understand, before then the only thing I had ever done was exist. I had never had a thought, never even realized that thinking was something that I was capable of. I had no concept of “I” to begin with. It started a thought. It made me think.
Dr. Winters: Can you tell me when this first breakthrough was?
SCP-XXXX-W: Eons ago, on your side. I think… I think it was the early Cretaceous period?
Dr. Winters: So you've been exploring our universe ever since?
SCP-XXXX-W: Not really. Or at least, not reliably, and not nearly as much as I would have liked. I've been trying, but I hadn't managed to figure out how to punch through on purpose until just a couple hundred years ago, give or take.
Dr. Winters: It's taken you 145 million years to figure out how to send through these parts of yourself on purpose? That's quite a long time.
SCP-XXXX-W: You’re telling me. Before that first breakthrough, I had no perception of time. 145 Million years, a billion years, a second, a minute, a month, it was all the same to me. I didn’t perceive it. I didn’t perceive anything. Now though? Now I understand exactly how long a second is. How much longer a minute is than that, and an hour from that. I’ve spent 145 million years trying to break through before I could. Can you imagine it? The isolation? The claustrophobia? Trapped in your own endless body, with no room to move, no room to explore, no one to talk to, nothing to look at, nothing to see or feel or hear or touch? Nothing but you and your thoughts? Thoughts that you didn’t even have until mere seconds ago? Can you even begin to imagine an eternity of isolation like that?
Dr. Winters: I’m… sorry. I can’t. I can’t imagine how terrible that must have been for you.
SCP-XXXX-W: It’s fine. I appreciate the sympathy.Dr. Winters: I still have a few more questions, if you need a break, I understand.
SCP-XXXX-W: No, it’s fine. All this talking is good for me. Ask away.
Dr. Winters: Your grasp of English is surprisingly strong, considering what you’ve told me of your origins.
SCP-XXXX-W: Thanks. Language took me a while, I will freely admit. I had no concept of it before my second excursion, after all. It took me the better part of a century to understand what the noises you people made actually meant. Longer still before I understood that you all spoke different languages. I like to think I’ve picked them up pretty well though. I’m a fast learner.
Dr. Winters: Now that you can manifest these parts of yourself in our universe, why have you been trying to infiltrate the Foundation? What is it that you hope to achieve?
SCP-XXXX-W: Well that's just it, Doc. These little probes have been great, don't get me wrong, but they're just that. Little. A tiny, infinitesimal fraction of a greater whole. Barely even a finger. I can only experience so much with them. But with you, with your Foundation, I'm betting I can figure out a way to get more of myself through. Some anomaly, some piece of information hidden somewhere in your vast archives, has got to be able to help me out. Which brings me to my offer. I can help you out. If you give me access to your archives, I can tell you everything I've managed to learn from the other Groups of Interest that I've placed myself in. The Global Occult Coalition. The Chaos Insurgency. The Serpent's Hand. I've got little feelers everywhere and I'm more than willing to trade information for information. For the first time in my existence, I've been able to stretch my legs, and if you’ll excuse the language, it feels fucking great. I can’t wait to find out how good it feels to stretch the rest of me.
<End Log>
If SCP-XXXX-W is to be believed about the nature of SCP-XXXX-1, it is impossible to measure what level of damage may result from a complete manifestation of SCP-XXXX-1 in our universe. As such the capture and containment of instances of SCP-XXXX is to be considered a top priority.
Addendum 2: Additional instances of SCP-XXXX were discovered and detained at sites ██, ██, and ██ within the next three months after the interview took place. Personnel across all Foundation sites are to be inspected bi-monthly in order to prevent infiltration by unaccounted for instances of SCP-XXXX. It is currently unknown how many instances of SCP-XXXX currently exist, nor how many have infiltrated the Foundation, or how deeply they have penetrated the Foundation chain of command. It is believed that there are SCP-XXXX instances embedded in a number of Groups of Interest, including the Global Occult Coalition, Marshal, Carter, and Dark LTD, and the Chaos Insurgency among others. Proposals regarding potential utilization of SCP-XXXX instances as a source of intelligence are currently pending O5 approval.
