Object Class: Keter
Special Containment Procedures:
SCP-XXXX is to be stored in the library of anomalous books at Site-49 and can only be read by personnel with special permission from head librarian, Dr. Timothy Friedman, in study room 04. Personnel with an IQ over 120 or above are forbidden to read more than 25% of SCP-XXXX and are recommended to only read 10% to minimize the risk for psychological problems. When 25% of SCP-XXXX has been read the studies must be continued by someone else within the assigned research team at the time.
After trails with cognitively underdeveloped personnel of D-class, it has been determined that it is safe to read SCP-XXXX by anyone with an IQ under 100, but it should still be done with the same safety regulations as specified above. Editions of SCP-XXXX that are found outside Foundation containment – for example in electronic form on the internet or printed versions in second-hand bookstores – are to be destroyed. Continuations of SCP-XXXX written by instances of SCP-XXXX-1, however, are to be brought to Site-49 for containment.
Five instances of SCP-XXXX-1 are to be kept in separated cells at Site-49 at all times. All five instances are to have access to pen and paper and everything they write are to be brought to Dr. Friedman. Communication with any of the instances requires permission from Dr. Friedman. If any of the instances of SCP-XXXX-1 dies in containment they are to be replaced with a new instance. If none have been found on the field within a period of six months a subject from D-class with an IQ of 120 or higher is to be forced to read SCP-XXXX to completion. This is to be done under observation in study room 04. When the subject has been re-classified as an instance of SCP-XXXX-1 by Dr. Friedman, it is to be placed in the cell of the deceased instance. All instances of SCP-XXXX-1 – except the five in containment – are to be sought out and eliminated by Foundation agents.
Description:
SCP-XXXX is a memetic virus in the form of a collection of diaries. The collection consists of 10 original volumes – including an introductory prelude – and an unknown amount of volumes written by instances of SCP-XXXX-1. Each original volume, including the prelude, is approximately 100 000 words long and exist both in printed form and electronic form. The original volumes extend from November 25, 2002, to February 14, 2017, and the prelude covers the time from the author's birth to the date he started writing the diary.
The author's name was Frans Oscar. He was born in Stockholm, Sweden, January 29, 1985, and died by suicide February 14, 2017. Most of what we know about him comes from the diaries, but a lot of it has later been confirmed through interviews with his relatives, documents from Swedish authorities and traces on the internet. Frans Oscar was a bachelor of philosophy – specializing in philosophy of mind – but ended his life as a cleaner at Hornstulls service house at Södermalm in Stockholm, Sweden.
Based on hints at the end of the diaries it is believed that Frans Oscar gave SCP-XXXX it’s anomalous effects intentionally together with his close friend Dr. Martin Larsson, who worked as a cognitive scientist at Karolinska Institutet in Stockholm, Sweden, until he disappeared without a trace soon after Frans Oscars suicide. According to the diaries, Frans Oscar wrote a book about consciousness together with Dr. Larsson titled The connection theory of consciousness. After completing the book, Frans Oscar made one last entry in his diaries in which he wrote that he had ”finally solved the riddle”. During his entire life, Frans Oscar suffered from an irrational fear of death at the same time as he hated his own life. It is agreed among Foundation researchers that this inner contradiction is what Frans Oscar refers to as the riddle. It is unknown how their theory made it possible to solve this riddle and create the anomalous properties of SCP-XXXX. All attempts to find a copy of The connection theory of consciousness has failed so far. However, it does exist an earlier version of the theory that Frans Oscar wrote as a teenager, referred to in the prelude to the diaries, but Foundation researchers still haven’t been able to derive an explanation from it.
SCP-XXXX’s anomalous effects are best described with an explanation of SCP-XXXX-1. SCP-XXXX-1 is the collective designation of everyone who has read SCP-XXXX. When someone with an IQ of 120 or more reads SCP-XXXX cover to cover a slowly progressing psychological change begins within the mind of the reader that always results in the loss of the reader's original personality in favor of Frans Oscar's personality. The subjects reading SCP-XXXX will be completely convinced they are Frans Oscar after having read SCP-XXXX to completion. Some evidence suggests this is more than a psychotic delusion since about 1% of all observed SCP-XXXX-1 instances seems to be able to refer to events in Frans Oscar's life that it is not mentioned in his diaries. However, it is not clear yet if these are genuine memories or qualified guesses based on the contents of the diaries. More research is necessary to determine this.
Psychological changes become detectable after 5% of reading SCP-XXXX. No matter the initial interest in the diaries, the reader acquire an abnormal interest in them at this point. This leads to an addictive behavior. Subjects often lack insight into these early changes and explain away the symptoms with a normal interest in the story or in the language. At 10% subjects usually begins exploring Frans Oscar's cultural interests, such as his taste in music and movies. Subjects typically explain away this as a normal curiosity. 20% in, subjects internalizes Frans Oscar's different temperaments. Regardless of their initial mood or mental diagnosis all subjects now adjust to Frans Oscar's psychological constitution; a general equanimity but with spontaneous anxiety about death and with a loathing towards his or her life. Foundation researchers who have written a log or kept notes will at this point begin to write far more than necessary for their research.
At 30% the writing develops into a mania in all subjects. Anxiety ensues if there’s no access to writing tools. At 40% subjects start to exhibit a strong interest in Frans Oscar's relatives, especially his mother and girlfriend. At first, subjects try to gain information about them on the internet, then attempts are being made to contact them. If successful, however, subjects get confused since they suddenly realize they have nothing to say to them. After subjects have read 50% of the diaries they start to confuse their own memories with those in the diaries. During this phase, subjects display confusion and anxiety, but the addiction to SCP-XXXX is too strong for them to stop reading it. If subjects are forced to stop reading at this stage in the process they are left in a permanent psychotic state which often results in suicide. During the rest of the process, the memories of the subjects continue to be displaced by the content of SCP-XXXX. This continues until the end of it when nothing is left of the subjects original personality. Subjects are classified as SCP-XXXX-1 at this point.
Although SCP-XXXX-1 seems to be a psychological copy of Frans Oscar, no instances of SCP-XXXX-1 has shown any signs of fear of death or hate towards their own life. Instead, instances of SCP-XXXX-1 displays euphoria. The only answer Foundation researchers have gotten from SCP-XXXX-1 as to why this is the case is that ”the riddle has been solved.” Attempts with torture did not change SCP-XXXX-1’s attitude.
SCP-XXXX-1 are continuously trying to get other people to read SCP-XXXX, often by starting reading groups or by placing printed copies of it in second-hand bookshops or small libraries.
The printed version of SCP-XXXX has only been found on three occasions since it was first discovered, but the electronic version has appeared once a year, either as a torrent on Pirate Bay or as a free e-book on Amazon. The uploader has as of yet not been identified but is believed to be instances of SCP-XXXX-1 or Dr. Larsson.
The Foundation is currently trying to understand how SCP-XXXX works and to prevent it from spreading any further. It is of utmost importance that Dr. Larsson is found and brought to Site-49 for questioning.
SCP-XXXX was brought to The Foundation's attention after two people – a teenage girl in Stockholm, Sweden and an elderly man in Gothenburg, Sweden – with no relations to each other was admitted to two different mental hospitals after having read 70-80% of SCP-XXXX and therefore displayed the exact same delusions.
Update 10-09-17
It seems as if the poems that are scattered throughout the prelude plays a causal role in the onset of the symptoms. When subjects do not read the poems the progress of the personality changes stops at around 50%. It is still not known which part of SCP-XXXX that causes the other 50% of the transformation into SCP-XXXX-1. Also, the word "Fblurbg" in the poems might be of importance. Before complete transformation into SCP-XXXX-1, hearing the word causes the subjects to have a panic attack.
