SCP-XXXX

Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX is to remain in Vault-12, and should not be entered without approval from the current site director.

Description: SCP-XXXX is a wooden door. Upon stepping through SCP-XXXX, an individual becomes superposed between an unknown amount of realities. Said individual will remain in this state until someone checks which reality they are in, destroying the other realities in the process.

A better explanation of this anomalous effect can be seen in the "Schrodinger Cat" thought experiment. If a cat is in a box, an outside observer would be unable to know if said cat was dead or alive without opening the box. As such, until the box is opened the cat is both dead and alive. This special state of being collapses upon opening the box, wherein the cat is either dead or alive.

Similar to how the cat can be both dead and alive, subjects who enter SCP-XXXX exist in multiple realities at once. Furthermore, like said cat, a subject inside of SCP-XXXX will only exist in one of those realities when someone checks their location. This can occur by communicating with said individual, or by reading transcripts of past conversations.

Addendum 1:
The following is an experiment log recorded by Junior Researcher Grey. It should be noted that this experiment was originally supposed to be performed by Dr. ███████, while Ms. Grey observed and helped when necessary. However, due to a last minute familial issue, Dr. ███████ was unable to perform this experiment, and authorized Ms. Grey to perform it in his place.

Note from Dr. Grey:
I am so excited! My first SCP! I cant wait!

Date: September 8, 20██
Time: 6:38 PM

Procedure:
D-3903 was given a portable communication device, and was instructed to enter SCP-XXXX. Below is a recorded transcript of said device.

D-3903: I'm in a dark room, but I don't think I'm alone.

Dr. Grey: What do you mean?

D-3903: I can see 7 shackles on the wall, but 6 of them seem to be broken.

Unknown Voice: Why do you enter my domain?

The sound of chains moving can be heard

D-3903: What are you?

Dr. Grey: What's happening?

Unknown Voice: Only one shackle remains… A shackle that has been weakening for ages…

D-3903: Please don't hurt me!

Unknown Voice: You are just a peon… A microscopic spec in the universe… Which is why it is all the more impressive that you're here…

D-3903: I don't want to harm you, once I find a door I can get out of here and never bother you again.

The unknown voice can be heard chuckling

Unknown Voice: The door is gone… Destroyed… There is only one way out of here, and that is through me…

Unknown Voice: Every time the door is opened I can feel it… A little bit more slack in my chain… A glimpse of light… Remove my chain and I shall remove yours…

D-3903: What do you mean by my chains?

Unknown Voice: You are chained with grief… with guilt… with life

Dr. Grey: Ask it what it would do if freed.

Unknown Voice: I would live… I would breath fresh air… Look at a clear sky…

D-3903: Why the hell are you shackled? I mean, that doesn't sound like a diabolical plan or something.

Unknown Voice: People fear that which they don't understand… That which has control over them… They lock them up… Experiment with them… Kill them…

Dr. Grey: Are you saying the Foundation did this?

The unknown voice once again chuckles

Unknown Voice: Maybe… Although there really wasn't a Foundation yet… Or at least, not as you know it…

Dr. Grey: D-3903, whatever you do, don-

Contact between Dr. Grey and D-3903 is lost. Following this encounter, SCP-XXXX should be monitored regularly for any unusual activity. Research into this unknown voice is ongoing.
