Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is required to be under 24/7 surveillance. No civilian is allowed within an 0.6km perimeter of SCP-XXXX's location. No personnel is allowed near SCP-XXXX alone and without clearance. Caution tape is to be distributed in the area to keep as many civilians away from SCP-XXXX as possible. There is currently no known way to keep SCP-XXXX closed, all passed attempts at locking SCP-XXXX have been unsuccessful due to locks mysteriously disappearing and personnel abruptly refusing to carry out orders to lock SCP-XXXX. SCP-XXXX is to be left alone until further notice.
Description: SCP-XXXX is what appears to be a closed entranceway that leads into an underground building located inside of a hill. The entranceway has a door that takes up about a third of its length. The door does not have a lock mechanism. The entrance is set into a rocky hill and has rocks and a short stone wall framing it. A path descends downwards towards the entrance.
Addendum: The first contact with SCP-XXXX can be traced back to the Winter War of 1939 when Soviet spies breached enemy lines and made their way into Finnish territory. SCP-XXXX resides in ████████, Finland. There are no records of SCP-XXXX's construction nor blueprints of what resides indoors.
One of the Soviet spies had documented the incident in detail; after setting up camp nearby one of them had started hearing scratching noises come from the other side of the door. The second night said man, identified as Ilya Volkov, was left behind at camp while others scouted the perimeters. After coming back Volkov had completely disappeared. No trace of him leaving the camp was evident and there was no sign of an attack. The same night another one of the men heard noises from behind the door, only this time he claimed he heard human voices and was convinced that Volkov was inside. The second man, identified as Sizov Maximovich, insisted on entering SCP-XXXX — the five (5) leftover men did not stop Maximovich but waited for him outside. After hours had passed three of the men went inside to look for Maximovich. None of them ever returned nor were any of them identified.
All of the missing spies were marked MIA in reports, the other of the two remaining spies, known only as "Yasha" died of bullet wounds, the sole survivor of the troop was identified as Epinger ████████ and is still alive as of the year 2020.
Ms ████████ recounted her experiences in an interview with one of our researchers. The following is a transcript of the interview.
Interviewed: Ms Epinger ████████
Interviewer: Dr Aien Moore
Foreword: Dr Moore sits down with Ms ████████. At the beginning of the interview, she is fidgety and becomes more aloof as Dr Moore proceeds with the interview.
<Begin Log, 12.23 █/█/20██>
Dr Moore: Can you tell me what happened the night Mr Volkov went missing?
Ms ████████: We had just arrived earlier that day to the site–we noticed the door but just thought nothing of it. We figured it might have been a base so we set up camp further away just in case. Ilya told us-as we walked away-he told us that he heard noises coming from behind it. We told him he was crazy, none of us-none of us heard anything.
Dr Moore: What kind of noises did he hear?
Ms ████████: Scratching, like little paws he said. I thought he might just have been homesick.
Dr Moore: Why is that?
Ms ████████: He has-had a little dog at home. Anatoly. A good dog. Always told me about how bad of a guard dog he was because he was so kind to everyone. Ilya always told to be like Anatoly. "We might be fighting an enemy but that enemy is also a person like you or me, probably also has very cute dog at home," he said.
Dr Moore: And what happened after he heard the noises?
Ms ████████: We set up camp for the night, ate food, had a few laughs to ease tension and anxiety. Me and the others-there were seven (7) of us total-we wanted to go see what we were dealing with in terms of environment, if there were enemy camps nearby, that sort of thing. Ilya wanted to play guard dog, he always did. He was very strong and very fast. If enemies appear, Ilya take care of himself very well. That is why it doesn't make sense to me that he would disappear. Ilya was very experienced man, taught me a lot.
Dr Moore: What did you do after he disappeared?
Ms ████████: We came back to camp, all empty. No sign of Ilya. We looked for him for hours… We were all very devastated after he wouldn't show up no matter how much we waited or how much we searched.
Dr Moore: Were you close?
Ms ████████: Ilya was close to everyone. Very good man. He had-he had plans. A lot of them. Wanted to help everyone. He helped me, a scrawny 18-year-old at the time, more than my own family ever has. I looked for him even after the second day…
Dr Moore: The second day was when Mr Maximovich went missing, is that correct?
Ms ████████: Yes—
Dr Moore: Can you tell me what happened on the second day?
Ms ████████: Yes, of course. We did more scouting that evening, found-we found an enemy camp. It was fast enough of a distance that we didn't feel the need to move ours if we planned quickly enough we could get rid of them. Passed by the door when we came back. Sizov looked uneasy as we moved passed it, kept glancing back at it over and over. Sizov was always a man of show not tell, didn't use words as much as actions. Quiet man, but had plenty of stories to tell. Cared for his comrades. He and Ilya knew each other from before the war.
Dr Moore: And the door, Ms ████████?
Ms ████████: Sizov said he heard muffled sound coming from it. He said it was Ilya screaming for help. We-we the others didn't hear anything. Sizov was just in shock from losing a friend as we all were is what we told ourselves. We ignored him, told him to go to bed. But he wouldn't budge. Need to go save Ilya, he said. The others told me and Yasha to go to bed, they will wait for Sizov and laugh at him for chickening out in one minute…
Dr Moore: And? What happened then, Ms ████████?
Ms ████████: … He never came back. I'm a light sleeper and woke up multiple times while the others waited for Sizov. I could hear the starting to get worried when the moon was high up in the sky and there was no sign of Sizov. I heard them go in. Never… never heard them come back. [inaudible].
Dr Moore: Ms ████████?
Ms ████████: I could… I could feel something. I had my eyes closed but I could *feel* it. I could hear it.
Dr Moore: Hear what, Ms ████████?
Ms ████████: It was like the devil. I— I'm… I'm sorry I need a break if you'd let me?
Dr Moore: Of course, Ms ████████.
