Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be kept in a 3 x 3 x 3 m room with walls made of heat treated stainless steel. The containment cell must be cleaned and sterilized thoroughly once a month by no more than one D-Class personnel.
All personnel should be dressed in full hazmat gear when entering the subject's containment cell. Personnel are not allowed to touch SCP-XXXX unless researching or permitted by higher-ranking personnel. When exiting containment, personnel must go through airlock and decontamination. If any personnel manage to leave containment before decontamination is complete they must be terminated and have their remains incinerated.
Inspections of the concrete bench are to take place immediately after cleanings, experiments on the moss, and attempted removal of moss. If the bench has any new chips, cracks, or holes, the air in the room must be raised to 80°C until all stray moss particles have been killed and cleaned away.
In the event of a containment breach, all organisms contaminated with the moss are to go through chemotherapy, unless the moss growth has reached stage four. If the moss growth has reached or continued past stage four, the organism is to be terminated and have their remains incinerated. Should any moss begin to grow outside of containment or the site, MTF unit Epsilon-9 are permitted to terminate all instances of SCP-XXXX, dormant or otherwise.
Description: SCP-XXXX is comprised of a concrete bench1 48 cm tall, 160 cm long, and 71 cm wide covered in an organism resembling thuidium delicatulum, or fern moss. The moss displays no anomalous properties until it comes in contact with a living organism or an attempt to remove it from the bench is made. Moss not in contact with another organism is considered dormant, while moss taking over another organism is considered active.
All attempts to clean the bench of moss have ended in failure. After scraping, power washing, sterilizing, and even spraying the bench with weed killer, the moss has always returned. The bench itself does not seem anomalous and has chipped with many cleanings, but it should not be broken. The moss may be deeply rooted into the airholes in the concrete, and breaking it may release moss particles into the air. Whenever the bench chips, sterilization of the room must take place.
When in contact with a living organism, now referred to as the subject, the moss closest to the subject will begin to move and attempt to make contact with the subject, until at least a 1" diameter of the subject's skin is covered with SCP-XXXX. Direct contact must be maintained for at least thirty seconds before the process of taking over the subject can begin. The process proceeds as follows:
- Moss covers 1" diameter of subject's skin.
- Moss seeps into subject's skin after thirty minutes and begins to grow and spread through subject's flesh. The only visible symptoms of the moss spreading are the initial area of contact and a green tint to subject's flesh.
- As the moss spreads to different muscles and organs after twenty four hours, the affected areas cease to function even though the subject feels no difference or pain. Moss will also begin to grow in small patches under joints, such as the armpit.
- Subject is legally declared dead when moss reaches the subject's heart and stops it, however, the subject can still function normally. Symptoms of this stage are pale skin and an irregular heartbeat. This usually takes between two and three days total to complete.
- When the moss spreads to the subject's brain, all brain power stops, and the subject will begin to aimlessly wander. Moss growth slows significantly once it reaches the brain stem, so this process takes about four days after the heart is contaminated. Symptoms of this stage are wandering, moss growing in hair, and glazed facial expressions.
Up until stage four the moss inside the subject can be killed with chemotherapy, and the effects reversed. Once the moss takes over the heart, however, the only thing keeping the subject "alive" is the moss inside of them. The moss appears to be able to perform the functions of all organs except the brain.
When the subject's brain has finally been taken over by the moss, they will attempt to leave any building they are in. Once they are outside, they wander until they find a place where moss can thrive. The subject will lie down and enter a comatose state, during which the moss will grow through their skin and spread around the area. Growth usually stops between one and five days. It appears this process of taking over an organism and finding a new place to spread is how this moss reproduces, as it has never been observed being pollinated or releasing spores.
The Foundation was made aware of SCP-XXXX when missing persons reports in ████████, Oregon began to pile up. They sent agents to investigate the common area in all the reports, and found SCP-XXXX to be the source of the moss spreading. MTF unit Epsilon-9 was tasked with setting up a quarantine around ████████ ██████████ Park and terminating all other instances of SCP-XXXX while Foundation agents moved the bench to Site-64.
Test A - June 3, 20██
Subjects: D-4983, D-976, D-7620
Procedure: D-4983 was instructed to touch the moss with his hand, D-976 was instructed to touch the moss with his foot, and D-7620 was instructed to sit on the bench. All D-Class were Caucasian males of average health, weight, and height. They were 24, 24, and 26 respectively.
Results: D-4983's heart was stopped in two days, three hours and thirty-four minutes. D-976's heart was stopped in three days, four hours and one minute. D-7620's heart was stopped in two days, one hour and fourty-six minutes.
Analysis: SCP-XXXX grows at a constant rate no matter the original point of contact.
Test B - June 20, 20██
Subject: D-137
Procedure: D-137 was instructed to touch the bench for one minute. After confirmed contamination, he was temporarily moved to an isolated humanoid containment cell for twelve hours. After twelve hours, he was brought to the site hospital ward and treated with chemotherapy. It was suggested by one of the researchers that chemotherapy may be able to slow or stop the process of the moss spreading, due to it's rapid growth.
Results: D-137 successfully recovered within fourty-eight hours and returned to his day-to-day duties.
Analysis: Chemotherapy appears to be a good containment procedure. Due to the nature of SCP-XXXX, any subjects contaminated must be treated with chemotherapy within twelve hours of initial contact.
Test C - July 16, 20██
Insert test log of initial contact to head
Test D
Instert test log of chemotherapy after stage four
Test E
Insert test log of chemotherapy after stage five
Addendum XXXX-A: Interview
Interviewed: James ███████████
Interviewer: Dr. Elliott
Foreword: James2 ███████████ was found sleeping on SCP-XXXX after the Foundation was called to investigate people disappearing after visiting ████████ ██████████ Park in ████████, Oregon. He told Foundation agents as soon as they arrived that he knew what was happening, so he was taken in for questioning.
<Begin Log>
Dr. Elliott: What is your name?
James: It's uh… James ███████████. Can we get this overwith quickly?
Dr. Elliott: Why?
James: The moss works fast.. it uh… it'll take over in about one day I think?
Dr. Elliott: (She looks confused.) Please explain.
James: The moss on that bench… takes over whoever touches it. Kinda makes 'em like a zombie, ya know? 'Cept I never seen someone with the moss attack anyone. They just kinda… go somewhere and die.
Dr. Elliott: Why did you sleep on it then?
James: (He shrugs.) I don't have anything else to do on this fuckin' planet. I got no home, the shelters are all full… it's better than living on the streets.
Dr. Elliott: How so?
James: Well… I'll be helpin' the moss. Helpin' it take back ████████.
Dr. Elliott: Take back ████████? Why?
James: Well, ████████ was a really pretty place before we got here. Forests, animals, rivers… then we came and fucked all that up. The moss just wants to make ████████ like it was before.
Dr. Elliott: How were you made aware of the moss?
James: Saw a dude leave it in the park one night about… uh… I think a year ago? Then people who touched the bench started dyin' in the forests nearby. I didn't catch his face though.Dr. Elliott: (She pauses for a moment, then clears her throat.) I think… that… that's all I need.
James: Okay.
<End Log>
Closing Statement: Dr. Elliott cut her interview time short and left the room in a hurry. When questioned why, she admitted she was worried about being infected herself. She had James terminated and the room sterilized and was the first person to experiment on the moss.
