Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX cannot be contained by any literal means, but chooses to reside in its room. SCP-XXXX's room is 5x5x5 metres and only contains an interview desk with three chairs, two on the side with the entrance, one on the other, along with basic lighting. The Entity's quarters are to be guarded by 2 (two) Tactical Response Officers, and the door is to be secured via an 8-digit numpad and an eyeball scanner only accessible to Level 4 Personnel.
The inside of SCP-XXXX's quarters are not monitored via security cameras nor any other means. (See Incident Report XXXX-C)
Description: SCP-XXXX is a humanoid entity that has no physical form. Instead, SCP-XXXX's form can be seen by the light behind the entity being bent and distorted, making SCP-XXXX appear as if made of perfectly clear water. It cannot interact with physical matter in any way, and does not produce any infrared radiation or otherwise, only manipulating visible light. How SCP-XXXX is capable of doing this is unknown. SCP-XXXX speaks with a Southern-English accent, but does not speak via sound-waves but instead via a form of instantaneous telepathy. Their speech obeys situational attributes such as distance and echo, and this appears to be by choice of the entity itself. Basic electronic recording devices can pick up SCP-XXXX's speech, and this appears to be also by choice of The Entity.
SCP-XXXX claims to know everything that has ever happened, what is currently happening or shall ever happen, but it comes at a severe limiting factor that it cannot speak of the future to people who can influence it. Every piece of historical information given by SCP-XXXX that could be proven has been proven correct, and the few pieces of future information given by SCP-XXXX have been seen to pass, aside from events that have yet to happen (See Addendum XXXX.5)
SCP-XXXX arrived at the facility on ██/██/████. Security personnel situated outside the facility reportedly saw The Entity "Appear out of thin-air". The Entity politely told the personnel that they were going to be SCP-XXXX and gave the exact co-ordinates of where they would be situated. Due to how SCP-XXXX was invulnerable to any means of restriction, and the clearly anomalous nature of SCP-XXXX, they were processed and placed in the containment area they'd previously stated they'd be in.
Once housed, SCP-XXXX explained their omniscient powers to nearby personnel, prompting them to be classed as 04 level classified until further review.
Notes from Dr. Keith Roswell: SCP-XXXX was not placed in their requested quarters because they requested it, but placed there as facility regulations mandated it. Despite having the ability to pass through walls and really be wherever they want to be, they choose to stay inside what is really an upgraded broom closet.
Addendum XXXX.1: Interview Log
The following was the first interview between Dr. Keith Roswell and SCP-XXXX. The interview took place outside of SCP-XXXX's quarters and instead in [DATA EXPUNGED] 9 days after SCP-XXXX was housed, once SCP-XXXX had been declared safe to interview.
Interviewer: Dr. Keith Roswell
Interviewee: SCP-XXXX
[BEGIN LOG]
SCP-XXXX: A pleasure to meet you in present, Doctor Roswell. Apologies for making you hasten through your Tuna sandwich, it looked delicious.
Dr. Roswell: I…
SCP-XXXX: I know, I know, I expected the briefing wouldn't be enough to prepare you. Well, I knew. Feel free to ask the million dollar question, you're going to anyway.
Dr. Roswell: …Who are you?
SCP-XXXX: The one of only two limits to my knowledge. I have no idea who I am or how I came to be here, but we'll get onto that tomorrow.
(SCP-XXXX smiles at Dr. Roswell. There is a pause of 3 seconds before SCP-XXXX sighs.)
SCP-XXXX: Alright, I've had my fun, I'll stop leading you on. Go ahead and interview me.
Dr. Roswell: …Hm, yes. You claim to know everything that has or will ever happen.
SCP-XXXX: Correct.
Dr. Roswell: That sounds like a lot to remember.
SCP-XXXX: It is, isn't it? I'd liken my memory to a giant library, one I can easily access and find whatever I wish to find. I can tell you the timeline of every atom in your body from the birth of the universe, if you'd like to know.
Dr. Roswell: I'm fine, thank you.
SCP-XXXX: A pity, 2437 of them belonged to Cleopatra at one point. Dreadful woman.
Dr. Roswell: You must understand that, despite how much we want to believe you, you could be lying about your abilities. The information about my lunch, for example, could be explained by an instance of Telepathy, an ability we know you possess.
SCP-XXXX: Well, allow me to prove it to you. Think of a random event in history that you don't know of and ask me a minute but provable detail about it.
[END LOG]
SCP-XXXX was able to name ███ of the original members of the ███ ██████████ as well as [DATA EXPUNGED].
Notes from Dr. Keith Roswell: Well, that proves it. SCP-XXXX certainly seems capable of knowing every piece of the past. The method by which they do is still unknown. I'm keeping SCP-XXXX Level 04 Classified since their knowledge of all things, especially the ███ ██████████, would be devastating if leaked to the lower levels.
