Edifices adapted for the drastically changing nature of human activities and environments after SCP-6883. Not pictured are the remaining 6 billion individuals on the planet, smear marks, and cockroach droppings.
Special Containment Procedures
As of September 15, 2025, SCP-6883 is deemed neutralized after the widespread application of the Ennui Protocol. Edifices and natural environments are to be remodeled to temporarily accommodate the new body structures and nature of human beings. A worldwide return to the standard human form is expected within three months.
Description
SCP-6883 refers to the spontaneous transfiguration of human individuals, generally workers and salary people, into human-sized entities resembling the American cockroach (Periplaneta americana). It is mainly localized to 12 cities in the Czech Republic, particularly in Prague.
The primary victims of SCP-6883, designated SCP-6883-1, are individuals who suffer from moderate or severe depression, are overworked, and have experienced burnout episodes. Another common trait is that they have histories of failures, as well as traumatic events.
SCP-6883 manifestations primarily occur at nighttime, when the victims have entered deep sleep. After approximately two hours of deep sleep, a cocoon will rapidly wrap around the subject, demanifesting after the individual wakes up, now a fully-turned SCP-6883-1 instance. Once converted, the individual will experience limited mobility and cognitive dissonance, although their sanity notably remains at a baseline level over long observation periods. Attempts to break the cocoons have unilaterally ended in failure. Noospheric, memetic, and psychological techniques are similarly ineffective in communicating with the victim.
Interviews indicate that the dreams of SCP-6883-1 instances mainly occur from the first-person point of view and consist of crawling through a variety of landscapes, greeneries, and empty fields with intensified feelings of euphoria.
Many instances have often described a Baroque-style castle overgrown with trees, referred to as SCP-6883-2. It is described as featuring towers composed of documents, papers, and office supplies. Notably, Foundation personnel report that this castle evoked strong nostalgia and longing. Upon entering SCP-6883-2, the subjects report experiencing a feeling of lightheadedness, which is followed by cessation of sleep.
They also report seeing SCP-6883-3, often described as 'building-sized piles of scrap and blocks' composed of foliage, machines, and several greeneries, that can assemble into a man'. SCP-6883-1 instances often express mild hostility upon discussion of SCP-6883-3, calling it an affront to their happiness. In reality, SCP-6883-3 refers to the 43,500 metric tons of metallic and organic blocks currently stored in Site-345, near the Alpine Mountains delineating Italy and Austria.
Aviatica Background Report
GoI-503's logo since 1990.
Analysis indicates that SCP-6883 is connected with GoI-503 ("Aviatica").An anomalous journalistic organization focused on publicity stunts and large-scale social change., which in turn links back to the Administrator, a former reporter and journalist. As Aviatica is decentralized and composed of journalistic cells led by an officer called an Arch-editor, as well as its dealings with the anomalous world, regular contact with its constituents has been difficult to fully establish, although delegations are sent to entertain Aviatica's offers. Aviatica primarily compensates for its insufficient manpower and physical scope via the use of avian drones, robotics, software, and information-based deals.
Due to Aviatica's connections with several high-profile news outlets and anomalous groups, the Foundation currently pursues a cordial working relationship with it as a source of information in the anomalous and occult in exchange for secrecy, protecting journalists and providing potential scoops. Meanwhile, both GoIs are receptive to inculcating each other's members.
The Administrator has approximately 10 years of service under Aviatica, before moving to the Foundation as an Agent. They have been involved in the highly classified EVNT-ALPINE-01, an Aviatican expedition to the Western parts of the Alpine Mountains to investigate an anomaly connected to SCP-6883, as well as a failed peace treaty involving several anomalous entities such as the life-givers of the forest.
O5-13 Interview-6883 Report
O5-13, stationed in the Czech Republic, is one of the individuals affected by SCP-6883. On May 19, 2025, they were interviewed via an online meeting subjected to heavy memetic filters. Although O5-13 can no longer vocalize their thoughts, they were still able to perform tasks using a keyboard. The details of the conversation are provided below:
Aviatica Report-6883
One of the residences of the Administrator, previously used for Aviatican activities two decades ago.
Five days after O5-13's interview, the following recording was obtained via secret data recorders implanted inside the Administrator's brain, under the orders of five O5 members lead by O5-1. The Administrator was resting in their home in Venice, Italy, as they conversed with Mr. K., a former colleague and a high-ranking officer of GoI-503 ("Aviatica").
The following conversation was recorded:
Administrator Behavioral Log
The Administrator transformed into an SCP-6883-1 instance five days following their conversation with Mr. K. The phrase 'MUTARE MUNDI' was engraved on their carapace.
Footage involving the Administrator's behavior in the previous days has been analyzed after psychological investigations ordered by O5-1 has determined abnormal behavior on their part. The transcript of Log #55, which is the most notable due to its anomalous effects, is provided below. O5-13 do not recall the incidents that transpired in these logs after extensive psycho-memetic analysis.
SCP-6883 Mandate of the Foundation
Several cockroach swarm attacks were then reported near the forest in extranormative space, with the loss of approximately 95 percent of all who have made it their abode. According to monitoring stations near the field of names, a 20km wide, 150m-tall castle, referred to as SCP-6883-2, has manifested, with approximately 4,300,000 cockroaches of varying sizes enabling it to levitate. above the greeneries in the chimneys. Meanwhile, the socialites of the grounds attempted to evacuate from the SCP-6883-1 instances, although they incurred losses up to 90 percent.
Thaumaturgic presence in the no man's farland have dropped to negative levels - thaumaturgic responders have reported the loss of function with most of their equipment, as well as significant transformations of several MTF forces accompanying them into SCP-6883-1 instances. It is hypothesized that significant levels of thaumaturgic energy have been obtained from the the stacks of greeneries.
After destroying the crux of the meadows, SCP-6883-2 has moved towards Venice in the span of two weeks. It then fixed its location, hovering over the city.
Three days after the disappearance of the Administrator, 80 percent of all Foundation Sites worldwide around the world lost contact with SCiPNet, following reports of destruction due to thousand-strong cockroach swarms. Physical entry into the Sites has been practically rendered impossible due to dense foliage, barriers composed of cockroach carapaces, and castle-like edifices. Meanwhile, all of the O5 Council members, save for O5-13, are reported as missing.
Five days afterward, a Foundation Class-1 mandate was signed by the Ethics Committee. The mandate, announced globally through public and Foundation's channels, is provided below:

Following this announcement, the Foundation has redesignated SCP-6883 as Thaumiel.
Foundation Collapse Report
Only 12 percent of all active Foundation assets can combat SCP-6883. Led by O5-13, they evacuated to Switzerland, alongside members of Aviatica, led by Mr. K. Major Sites, such as Site-19, Site-24, and Site-120, are now compromised.
Following the Foundation announcement, approximately 124,562,000 individuals worldwide, all of whom suffer from varying levels of depression and harbor feelings of mediocrity, have approached Provisional Sites set up by the Foundation over the past month to turn into SCP-6883-1 instances after undergoing thaumaturgic psychological techniques.
Analysis has only revealed that most of these individuals are only mildly affected by Foundation memetic agents and have come by their own volition. Meanwhile, more aggressive campaigns by the Foundation are focused on providing relief and purpose to citizens by turning them into highly-coordinated SCP-6883-1 instances.
Afterward, these individuals are released back to their ordinary environments, with memetic agents normalizing their appearances. They display heightened levels of happiness, optimism, and productivity at work.
At the start, approximately 98,000 SCP-6883-related accidents occurred worldwide due to the lack of familiarity with cockroach-based functions. 11 Foundation Sites were then forcibly occupied by SCP-6883-1 instances, resulting in the release of 235 anomalies, all of which turn into deformed SCP-6883-1 instances. Due to freed Keter anomalies, many parts of the Americas and Asia have been obliterated. However, the world's population has not reacted negatively to the released entities or the incidents, and instead cheer and continue their daily routines.
Notice from O5-13
The following message is the transcript of O5-13's emergency declaration following the near total collapse of the Foundation.
We are the last foundations of the Foundation, but we still have a plan. We will fight for humanity's form, this time with their happiness in mind.
We will commence Operation UOMINI to revive SCP-6883-3, also known as "Uomino". All remaining thaumaturgic personnel and equipment of the Foundation are to be immediately transported to Site-354 and the Alpine outposts to commence preparations for channeling conduits into SCP-6883-3.
"Man In High Castle" Report
Approximately 81 percent of humanity has been converted into SCP-6883-1 instances, with record-high advances in workplace productivity, scientific progress, and quality of life, according to a Foundation update report released by the Ethics Committee. Meanwhile, the Foundation and Aviatica has launched an expedition to Venice, in hopes of luring the Administrator to Bolzano or the Western Alps in order to initiate Operation UOMINI.
O5-13 was included in the roster for the expedition after the development and successful testing of the V-2 Eckernacht Noospheric Apparatus, a cerebral microchip which allowed for telepathic communication with other individuals. They were chosen due to their familiarity with the Administrator, lessened hostility of SCP-6883-1 instances in their vicinity, and augmented flight capabilities.
In the aftermath, O5-13 is declared as the new Administrator, with Aviatican officers helming the O5 Council. Due to SCP-6883-Ω's death, neutralization of SCP-6883 is observed, with individuals in Northwest Italy and Austria gradually returning to their human forms. A worldwide return to the human form is expected after three months.
