 Item number SCP-398 Object Class, Euclid Special Containment Procedures SCP-398 is contained behind a reverse airlock-style containment chamber locking mechanism, consisting of at least three steel doors and an atmospheric reduction system. A minimum of two guards must be stationed at the doors, remaining at a 50 meter distance from the entrance to the SCP. Description SCP-398 appears to all subjects as a hallway of some description, however, details differ between accounts. It is first seen as a hallway with white walls, plain wooden doors 20 meters apart and approximately 2 meters high, and brass handles with no special attributes visible. This detail is consistent across all accounts. It was found on location at ██████, and upon investigation, a dimensional containment site was set up around it. The remainder of the original building surrounding it is unremarkable, and has been demolished as such. Addendum 398-A, Agent ████ sent a research subject equipped with a handheld video camera with transmission feed. Agent ████ travels down the hall. The hall. It's changed. Transmission showed no change in the hall's appearance. Changed. How so? It's different from when I walked in. Dark wood-paneled walls, red carpet, and many paintings. I like it. Continue Agent. Go in further. Roger, sir. Continuing. Agent ████ continues until the appearance of several doors. The door is similar in design to others in the location. Agent ████ opened the one on the immediate right. Yes, sir. Agent ████ opens the door to reveal an unpainted and unburnished room. It seems to be a cafeteria. A cafeteria? Is there anyone in it? You can't see it? There's no one in here. Just tables, chairs, and a buffet-style layout. It's real good, and I haven't had lunch yet. Noted. Open the door opposite this room. Agent ████ opens the door. It is identical to the first room in appearance. This one? It's a bedroom. A bedroom? Yes, a child's room. The one I wanted from a catalog when I was a kid, because it had Spiderman sheets. We couldn't afford it. Noted. Continue. Open one more and return, Agent. Agent ████ exits the room and opens the one next to it. Again, it is identical to the first two. She can't be here. What Agent? What's through this door? My old girlfriend. But she's married now, expecting a kid. The person in the room can't be her. Agent ████, please return now. Agent ████ lowers the camera, and only the floor can be seen. I want to make it right, baby. Shhh. It's okay. Don't cry. It was all my fault. Footsteps are heard, and in a soft, incomprehensible crooning from Agent ████… Agent ████… did you hear me? I'm so sorry I let you go. Don't you worry. It won't happen again. Agent ████… You will turn around, close the door, and return to the outside. That is an order. With all due respect, sir. No. I can make it work this time. At this point, the camera is lifted, and then the fee is abruptly ended. Addendum ████, 398B. After loss of Agent ████, Class D personnel are to be sent into SCP-398. Well D-193 and D-216 are sent equipped with handheld video cameras to explore further. Transcription of audio follows. Begin log. Skip to 12 minutes 41 seconds. Right, you two. Continue onward. Understood. Transmission shows the same hall seen in Addendum 398A. D-193 appears to be in front of D-216. D-216's speed shows D-193 walking ahead of him. There are doors. Shall I open one? No. Continue onwards. The Class D personnel continue. After a few meters, D-216 gasps. D-216? What's wrong? No answer is heard. He seems to be unconscious, sir. His vitals have dropped out. He's dead. Leave him and continue D-193. Roger, sir. Seconds pass. The hall is changing, sir. The feed shows no change. Describe. It's starting to look like the corridor outside of my old cell. I'd never wanted to see this again, but it looks like it gets better just up ahead. Open the door to your left, 193. D-193 opens the door. It is identical to the room seen in Addendum 398A. A burst of breath is heard from D-193. His heart rate rises. What is it, 193? It's the basement we had in the house I lived in as a child. I always hated it. I never went in. D-193's voice is shaky. Oh, god. Can you hear that? There are voices. Something's down there. Nothing can be heard except D-193's breathing. What are they saying, 193? I don't know, but I'm getting out of here. It will get better further on. It has to. D-193 starts to run on down the hall. Negative D-193, return at once. I can't, sir. Just terrible back there. It will be better further on. Much better. The log continues for ██████ minutes, until the fee is inexplicably cut off. End log.
