SCP-[...] is to be stored in a standard low-threat anomalous object locker at Site-██. Access to SCP-[...] is restricted to Level 2 personnel and above with prior approval from at least two Level 3 personnel. The locker is to be locked at all times, and the key is to be stored in a separate secure location.

SCP-[...] is to remain powered off unless testing is authorized. During testing, a single D-class personnel is to be allowed access to the computer, under close observation by at least two Level 2 personnel. After the testing period, SCP-[...] is to be shut down, and the D-class personnel is to be administered Class-A amnestics and reassigned to standard duties. All testing is to be documented and reviewed by at least two Level 3 personnel.

The computer is to be connected to a isolated network outside of Foundation Intranet to prevent any potential data breaches.

SCP-[...] is an IBM Aptiva 2140 desktop computer, manufactured in 1997, running the Windows NT Workstation 4.0 operating system. The computer's hardware is unremarkable and consistent with models of its time, showing signs of age and wear. SCP-[...]'s anomalous properties manifest through an application shortcut labeled "PersonaConfig.exe" located on the desktop.

When SCP-[...] is powered on and the application is launched, it opens a graphical user interface (GUI) with the following sections:

• Personality Traits: This section allows the user to adjust various personality traits, including extroversion, agreeableness, conscientiousness, neuroticism, and openness to experience. Each trait has a slider with a range of values from 0 to 100, with accompanying descriptions and examples of how the selected traits may influence behavior. The interface provides a "reset" option, which restores the user's personality traits to their default state.
• Tastes and Preferences: Users can modify their preferences in this section, including favorite foods, genres of music and literature, hobbies, and leisure activities. The interface provides a search bar to explore and select specific items or categories, with the option to add custom preferences.
• Social Circle: This section displays a list of individuals known to the user, categorized as 'Friends', 'Acquaintances', 'Strangers' and 'Enemies'. Users can add or remove individuals from these categories, with a search function to locate specific people by name, location, or relationship. When a person is added to a category, SCP-[...]'s anomalous effects will cause the targeted individual to perceive the user as that selected category, altering their memories and behavior accordingly. However, this effect is not instantaneous and may take several hours to manifest.
• Memories: The 'Memories' section provides a timeline-based interface, allowing users to explore and modify surface-level memories. Users can add, remove, or edit memories, with a particular focus on childhood recollections. The interface includes a 'Restore' function, which can recover a significant portion of the user's early childhood memories, often leading to emotional responses. However, this function is not always successful and may result in the creation of false memories.
• Physical Appearance: This section provides a detailed 3D model of the user, allowing for alterations to height, body type, facial features, skin tone, hair style and color, and other physical attributes. The model updates in real-time, providing an accurate representation of the user's chosen appearance. However, the changes made to the user's physical appearance are not always consistent with the laws of physics and may result in unrealistic or impractical changes.

The interface of SCP-[...] was designed for Windows 95, with buttons, scrollbars, and dialog boxes consistent with that era's design language. The application is highly responsive and intuitive, with tooltips and help sections providing guidance to users. Despite extensive searches, no executable file or source code for the application has been found on SCP-[...] or any connected networks.

SCP-[...]'s anomalous effects become apparent upon shutting down the computer. Any changes made to the user's personality, tastes, social circle, memories, or physical appearance will manifest in reality. Individuals affected by the 'Social Circle' modifications will genuinely believe they have a said relationship with the user, with corresponding memories and emotional responses. These effects persist indefinitely and are resistant to amnestic treatment.

On ██/██/200█, Foundation agents were dispatched to investigate a potential anomalous incident at ███████ High School in ██████████, ██████. A student, later identified as Ms. ████████ █████, had reported a sudden and inexplicable change in her social relationships. Ms. █████, who had been bullied and ostracized by her peers, claimed that several students who were previously hostile towards her had become friendly and supportive overnight.

During the investigation, Ms. █████ led agents to an abandoned storage room within the school, where SCP-[...] was discovered. The computer was found powered on, with the "PersonaConfig.exe" application open. Ms. █████ admitted to finding the computer and using it to alter her social circle, unaware of the full extent of its anomalous properties.

Interview with Ms. ████████ █████:

<Start of Log>

Interviewer: Dr. ███████, Level 2 Researcher
Subject: Ms. ████████ █████

Dr. ███████: Ms. █████, can you tell me how you discovered this computer?

Ms. █████: I was hiding in the storage room during lunch break, like I usually do. I saw this old computer and thought it on some games or something to pass the time. I didn't expect it to do... what it did.

Dr. ███████: And what exactly did it do?

Ms. █████: (Subject becomes emotional) It made people like me. I changed a few things, you know, to make myself cooler. But then I saw the social circle thing, and I thought, why not? So I added some people as friends, and... it worked. They started talking to me, hanging out with me. I didn't know it would actually change them.

Dr. ███████: Can you describe the application and its functions?

Ms. █████: (Subject provides a detailed description of the application's interface and features, corroborating the description in the main article)

<End of Log>

Subsequent interviews with individuals affected by SCP-[...]'s "Social Circle" modifications revealed that the changes in their perceptions and memories were profound and emotionally significant. The affected individuals genuinely believed they had formed close bonds with Ms. █████, often citing shared experiences and memories that aligned with the alterations made in the application. Amnestic treatment has proven ineffective in reversing these effects, suggesting that SCP-[...]'s influence on human psychology is deeply ingrained and resistant to memory alteration.

Research into the origin of SCP-[...] is ongoing, with particular focus on identifying the creator of the "PersonaConfig.exe" application. The Foundation's IT specialists are attempting to reverse-engineer the application to understand its code and potentially uncover any hidden functionality or security measures.

On ██/██/20██, a containment breach was detected when Dr. ████ ██████, a Level 2 researcher, entered the containment chamber of SCP-[...] outside of authorized testing sessions. Dr. ██████ used the computer to modify his own personality traits, tastes, and physical appearance, before shutting down the machine and exiting the chamber.

The breach was identified when Dr. ██████ began exhibiting unusual behavior and personality changes during staff meetings and interactions with colleagues. Colleagues reported that Dr. ██████ exhibited uncharacteristic behavior, such as increased assertiveness, a shift in personal preferences, and a more extroverted demeanor. The Site Director ordered an investigation, which led to the discovery of Dr. ██████'s unauthorized use of SCP-[...].

Interview with Dr. ████ ██████:

Interviewer: Dr. ████████, Level 3 Senior Researcher
Subject: Dr. ████ ██████, Level 2 Researcher

Dr. ████████: What made you enter the containment chamber and use SCP-[...] on yourself?

Dr. ██████: (Subject displays signs of embarrassment) I... wanted to see if it would work on me. I know it's not standard procedure, but I was curious. I thought, what if I could become a better version of myself? I didn't think it would actually work, but... here we are.

Dr. ████████: And what exactly did you change about yourself?

Dr. ██████: (Subject becomes hesitant) I... adjusted my personality traits, you know, to be more confident and outgoing. I also changed my appearance a bit, just to see if it was possible. I made myself taller and altered some facial features. I know it was foolish, but I was curious about the limits of the anomaly.

Dr. ████████: Have you noticed any other effects or consequences since the incident?

Dr. ██████: Well, the changes I made to myself seem permanent. I haven't been able to revert them, and amnestics don't seem to work. I... I'm sorry. I understand the seriousness of my actions.

<End of Log>

Following the incident, Dr. ████ ██████ was reprimanded for breaching containment protocols and endangering Foundation personnel. The Site Director emphasized the importance of adhering to established procedures and the potential risks associated with unauthorized use of anomalous objects.
