MSCP-053

Item #: MSCP-053

Object Class: Euclid

Hazards: Non-standard Spacetime, Sentient and Violent, Cognitohazard

Special Containment Procedures:

MSCP-053's outdoor containment area must be monitored 24/7 by cameras and its respective guards. All entities emerging from MSCP-053 must be killed immediately unless enjoined otherwise by personnel with LVL 3 clearance or higher, and recoverable specimens should be quickly stored in ██-█ before decaying. The entrance of MSCP-053 must be covered by iron blocks along with an iron trapdoor. The 3-block-thick concrete wall (12 blocks in length and width) surrounding MSCP-053 must be in acceptable condition at all times. Perimeter guards are free to search for damage after an outbreak had shortly occurred. Any form of damage, no matter the severity, should be reported to personnel with LVL 3+ authorization or directly to the Building and Repairing Department.

Upon discovery of significant damage, no testing is allowed to take place until the surrounding walls have been repaired. Tests involving MSCP-053 are only allowed to be conducted by a researcher with LVL 3 clearance and other staff members with LVL 4 clearance or higher. If testing takes place in the night, additional security personnel are to be on standby. Unlike standard tests, expeditions are no longer allowed to take place. Requests for an expedition are to be denied until further notice.

Description: MSCP-053 is a roughly 77° cave shaft of unknown origin, which extends far below bedrock with no known end. MSCP-053 appears to possess the ability to visually deceive humans who look at it, for example, making the bottom of the cave shaft seem much closer to them than it actually is.

MSCP-053 was first discovered on ██/██/██ by a villager from the town of ████, who reported to have seen “unearthly beings” emerge from the cave at night. His report was disregarded after a research team from the town was dispatched to examine MSCP-053 which they soon confirmed to be an ordinary cave shaft without knowledge of MSCP-053’s reality-bending capabilities. Two days after their exploration, their town was attacked by alien creatures, which resulted in █ casualties. Site-██ was contacted on ██/██/██ by the town council for protection against MSCP-053.

So far, ~1000 blocks of the cave shaft have been explored and over two tons of minerals were extracted in the process, proving it to be very rich in resources. Beyond y-level 0, however, compasses lose their functionality. For this reason, it is recommended to not venture beyond this depth. Clocks stop working below approximately 1000 blocks, but the exact depth has not been determined yet.

Beyond y-level 0, ores seem to emit a memetic effect that affects humans who view them by evoking the urge to mine them. Victims are lured in by reacting to visual stimuli as well as possibly other forms of stimuli that have not been discovered yet. While escaping from this memetic influence is possible, a more powerful stimulus or a distraction may be required to overcome it such as something that evokes fear, yet it is likely that long-term symptoms will still be present, especially after prolonged periods of exposure to these ores. (See addendum)

When MSCP-053's Outbreak Phase begins, waves of MSCP-053-1 instances will begin crawling out of MSCP-053. These events seem to occur exclusively at night and seem to last anywhere between fifteen minutes and over six hours. No exact determination of when and for how long this event might take place in the future exists as no clear indication has been provided by MSCP-053 or its entities during this phase.

MSCP-053-1 instances are animate and extremely hostile towards other living organisms, each of them vary in size, strength and mobility. They appear to be amalgamations of an unknown substance with a rough humanoid shape which includes distinct bodily features such as limbs and a head. However, these characteristics are not consistent among 053-1 instances.

Interview log: Expedition ██/██/██ (MSCP-053)

Interviewer: Dr. ███

Interviewee: D-9511

Note: This interview took place 5 hours after the incident. D-9511 was found unconscious lying next to MSCP-053’s entrance and was the only member of the expedition team that was recovered from the expedition."[BEGIN LOG]""D-9511 enters the room at ████ with his hands tied together.""Dr. ███: Greetings, we have some questions for you. Please take a seat.""D-9511 did as told.""Dr.███: Are you ready?""D-9511: Yes, doctor.""Dr. ███: Excellent. Do remember what happened?""D-9511: I think so.""Dr. ███: Good. Now, let’s get the most important question out of the way first. What happened down there? How’d you split up?""D-9511: We were attacked by a group of monsters. That’s how we split up. They tore the guards apart, and I mean literally. Swords didn’t do shit to them. They didn’t even flinch. The host was killed as well, I'm pretty sure, and the other Class-Ds tried to bring as much loot with them but weren’t successful.""Dr. ███: ...Shit. So, they’re all dead, huh. Swords were ineffective? Usually those things would die in a couple of hits. Were those monsters even -1 instances?""D-9511: I don’t know. They looked kind of similar to a -1, but they were much stronger than what we’re used to.""Dr. ███: So, would you say it was a -1?""D-9511: What is this question? I mean, it was close to midnight; we were gathering resources and ores all day. So—""Dr. ███: What? You should’ve already been back by then. Did the host know when to return?""D-9511: Yes. At least he said he did. I just—it was so weird down there.""Dr. ███: Weird? Did you notice any differences about the cave shaft the deeper you declined?""D-9511: Not really, other than the fact that it got quite dark and warm, even a bit eerie.""Dr. ███: Well, that is to be expected. You brought light sources, right?""D-9511: We did. We brought a few unlit torches to mark our progress along with a few flashlights.""Dr. ███: What depth did you reach before retreating?""D-9511: I got to about, I would say... 1000 blocks down, at least.""Dr. ███: Wait, what?""D-9511: I don’t fuckin’ know. Wait, isn't bedrock… 200 blocks deep or something?""Dr. ███: Around 60 blocks below sea level, and we’re lower than sea level. Are you sure you’re not exaggerating?""D-9511: Okay, what the hell? I swear it felt like we were at least a kilometer below the ground. Maybe it was because… No. It couldn’t have been only 60 blocks! All I had to do was look up. I held my thumb out, and it could cover the hole 10 times over.""Dr. ███: Interesting. At first glance, it really doesn't seem so—""D-9511: I know! I’m only realizing it now. I could have sworn when I glanced down before we started, I could see the bottom.""Dr. ███: That explains why you were so exhausted, but it doesn’t explain why the hell the host decided to keep going. What was his reasoning for that?""D-9511: He never told anyone. I guess...the host was just really eager to collect as many resources as he could. I wouldn't blame him, honestly. It was so comfy down there.""Silence ensues for a moment.""Dr. ███: You wouldn’t blame him because it was “comfy”?""At this point, D-9511 appears to be aloof and preoccupied with his own thoughts.""D-9511: Yeah, pretty much. It was…really welcoming down there. Almost felt like I could fall asleep. Only thing unusual was our equipment acting funny.""Dr. ███: What do you mean by “acting funny”?""D-9511: Our compasses when we were...what…80 blocks below the ground? They started malfunctioning. I mean...the compasses were spinning out of control.""Dr. ███: The host was eager to keep gathering resources? How many ores were down there?""For the next 30 seconds, D-9511 can be heard chuckling lightly between sentences. ""D-9511: A lot of ores. I-I've never seen so many in one place! Everything felt different down there—including the ores. It felt like a different dimension. I don't know what it was about them. This might sound mental, but it actually seemed like the host was being drawn to them—me as well, almost. I felt a dopamine rush every time I hacked away at them.""Dr. ███: We could be dealing with a cognitohazard if that’s the case. Anyway, do you need a—?""D-9511: The hell’s a—(D-9511 bursts out laughing)—cognitohazard?""Dr. ███: Just pull through. We’re almost done, yeah? How’d you escape?""D-9511 stays silent.""Dr. ███: How did you escape, D-9511? The entire expedition team besides you are missing. If you do not cooperate—""D-9511: I don’t know why he didn’t follow the procedure, okay? He never told me.""Dr. ███: Huh. Seems like you drifted off, but it’s fine. Let’s continue.""D-9511: What?""Dr. ███: How did you make it out? You’re the only survivor.""D-9511: I don't know how, okay? I just started climbing, until eventually, the creatures’ screeches quieted down. Once I was near the top, I looked back down, and the cave shaft’s suddenly made sense to me.""Dr. ███: Interesting. Well, pretty sure that's all of—""D-9511: I want to go back there. There was so much stuff that we missed, and the thought of that still pains me…""Dr. ███: Alright, I think we're done here."""Written by ThatCatJizo
