SCP-XXXX
Object Class: Apollyon
Containment Procedures: Due to SCP-XXXX extreme nature it would be impossible to contain with our modern technology. The one captured instance of SCP-XXXX-A-13 that is currently contained is sealed in a 5m by 5m by 5m cell with carbon arc lights shining from every possible angle as to reduce the casting of a shadow.
Description: SCP-XXXX is an anomalous event that took place in Dimension 72, universe 75.094-A. The event is still lasting to this day with no known means to slow or halt its progression. This event turns all shadows that are not being casted from an organic substance (Dead or alive) or clothes into a highly infectious virus shadow. If it touches any animal, including humans, it will begin to spread through the body at an alarming rate until it completely consumes the lifeform in a shadow. The shadow will then attempt to seek out the nearest life form. If successful, the shadow will cast its own shadow to that lifeform, while keeping itself whole in the process. These instances of SCP-XXXX are known as SCP-XXXX-A. SCP-XXXX-A is capable of fitting through airtight containment cells and power lines, wires, etc. These instances of SCP-XXXX-A are able to morph limbs into weapons, streatsch them, and thin them to the point that they pass through bonded molecules. A presumed 7.19 billion were thought to be dead in the first 20 minutes of activation. Faculty from several sites reported hearing the SCPs screaming before falling silent. All power was cut off 3 hours in, resulting in blackouts throughout all containment facilities except for Site 7 and Site 49. Site 49 houses an anomalous item known as SCP-XXXX-B. SCP-XXXX-B is a small flashlight that sits on a mirror. If you shine the flashlight on the mirror, a portal to our world will take place instead of the mirror. The mirror will always show a date on it, April 30th, REDACTED. This number is thought to be the date of when our universes shadows will "activate". Under no circumstances are anyone aloud to activate the portal. Communications logs from Site 49 read as follows,
"January 14 of the year REDACTED, this is Dr. Simmonally Walish. This was the first day of studying the new SCP, known as SCP-XXXX, object class safe. He found that this mirror leads to another universe, no, dimension entirely! This would mean that our theory on inter dimensional travel might not be to far away. This SCP could benefit humanity as a whole. Everything we learn about this knew SCP is so fascinating. As much as i would love to talk about the studies, i have a got of paperwork to do. Dr. Simmonally Walish, signing off."
"January 18 of the year REDACTED, this is Dr. Simmonally Walish. The knew SCP I have been studying may be a potential Euclid. It has started to produce some sort of shadow that when makes contact with you, drives you to the point of insanity. The shadow has been observed to manage to shrink itself tho pass through bonded atoms. This is troublesome when it comes to containing it, but more lights seemed to have contained it." An alarm starts sounding in the background of the log. "Huh? Some SCP just broke containment. I better go check it out. DR. Simmonaly Walish, signing off."
AT this point SCP-XXXX has broken containment. Every shadow in the world is now lethal.
27 minutes later, Dr. Simmonally Walish makes another log.
"January 18 of the year REDACTED, this is DR. Simmonally Walish. i was in the Sector C location where SCP-XXXX was located when i heard gunshots. You know what i see? The mobile task force group "Nine tailed fox" being torn apart by these, these, fucking shadow people, just to come back as one of them. About 20 guards and 17 D-class were in that hallway when the lights turned off. i was far enough away to where i wasn't surrounded by darkness… but the same can't be said for them. All I heard were there screams. Then the lights came back on. They all just looked at me and the other 30 or so personnel that were still alive then started running for us. Three others and i made it back to my office. we are hiding here for now, until this is contained. Dr. Simmonally Walish signing off."
This log came from March 3rd
"January… something, or was it february? March? Anyways, it has been quite a while since i have done a log so I will fill you in on what happened. Those shadows, we've started calling them "Shadowfolk" were at are doors. They taunted us, saying things like, 'Don't worry, you'll be dead soon enough.' and 'When you become one of us, you won't have to worry. Your torment will pleasure us,". They left soon enough, so we exited the room, which was our first mistake. We had ran out of rations so we tried to get to the nearest vending machine. About 5 minutes in we start to hear a deep thudding sound and coughs behind us. We all turn and see 682 himself, but covered in shadows. He was pleading for the pain to stop before he finally charged at us. Dr. Jause who was one of the survivors found a revolver on the ground and picked it up, but the fucking shadow of the gun spread all through his arm. He turned the gun to himself and blew his fucking brains out, but he still came back. Anyone remember SCP-001 "When Day Breaks"? Yeah just like that they wont even let us fucking die. Signing off."
March 7th
"Futile you resist but extinction is inevitable. If anyone happens to be alive, we will find you, and you will never be able to end your suffering."
