Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX can manifest in a room with a size of at least 25 metres long, wide, and tall. SCP-XXXX manifests at the mention of its name in any space matching or surpassing these parameters, along with the presence of reptilian organisms. Knowledge of the entity's name must be heavily restricted, with termination being an acceptable measure of containment if the name were to spread outside of designated personnel. SCP-XXXX is currently impossible to contain physically for extended periods of time, due to its peculiar ability to disappear if not paid attention to, and the events that may occur to distract personnel and electronic monitoring, though special functions have been put in place to ensure prolonged engagement, carried out by D-Class personnel for most of the unspecialized functions. These functions include, but are not limited in their entirety, to: communication, humorous engagement, feeding, entertainment, philosophical discussion, etc.
SCP-XXXX seems to remain in custody if some of these functions interests the entity enough. This allows for further probing into the possible origin of the entity. However, some engagements may disturb SCP-XXXX in multiple ways, possibly resulting in the loss of D-Class personnel, or C-Class and above currently interacting with the entity. During these times of disturbance, on site security forces are to be mobilized to deal with possible threats originating from SCP-XXXX, including the entity itself, or manifestations of SCP-XXXX, deemed SCP-XXXX-1.
During times of rest the entity may take, all personnel are denied access to any equipment that may cause loud or sudden disturbances, along with denying all access to the room. During times of temporary containment, it is discouraged to mention the entity's name, as it can disturb its rest, no matter how far away the name is mentioned, and can distract the entity from whatever it is currently doing or talking about. If the entity's name were to ever be mentioned in open air under or surrounded by no physical objects, it could result in a K-Class end of the world scenario, due to the anomalous nature of SCP-XXXX.
Description: SCP-XXXX manifests as a skeletal structure, similar to that of reptilian creatures, with many more notably crocodilian features, though has a feature no known reptilians have. This feature appears as two long appendages made of bone, with several other long appendages extending from each, with small, tattered amounts of unknown material, giving them a similar appearance to that of wings.
As well as having what appears as wings, a clear, viscous substance constantly coats the entity. This substance acts as a non-Newtonian fluid when in contact with SCP-XXXX, or any instances of SCP-XXXX-1. Upon removal from the entity or instances, it acts as a normal liquid. Consumption of this liquid is not recommended, as there is the possibility of life threatening illnesses manifesting within hours, from extreme cases of the common cold to [REDACTED]. This liquid acts as a flame retardant, in any case, though when in contact with the entity or any of its manifestations, it also acts similar to kevlar, reducing the damage of high velocity projectiles commonly used by military personnel.
SCP-XXXX has an extroverted personality. The entity prefers to talk in person, rather than through audio and video communications. However, there are moments where SCP-XXXX prefers to be left alone. During these times, all personnel without special permissions are disallowed communication with the entity. If any personnel were to perturb SCP-XXXX without letting them know first, it could result in the death of said personnel.
SCP-XXXX's anomalous properties are not easily discerned. However, other than their appearance, SCP-XXXX's properties manifests in the peculiar ability allowing them to grow proportionally to the size of the space it was summoned in. The process of summoning SCP-XXXX is simple. Mentioning its name in the presence of a reptile. Upon doing so, if proper conditions are met, it will take approximately 1 minute to 1 hour for SCP-XXXX to manifest. During this time, it is required personnel avert their gaze. This helps to quicken the process, though lesser anomalous effects often handle this. During the manifestation of SCP-XXXX, recording still works, though the outcome is often interrupted. However, video recording reveals the process in which SCP-XXXX manifests, though vaguely. It starts off with the reptilian organism dying seemingly randomly. It is soon followed by the corpse of the organism rapidly decaying, leaving behind only bones. After this, the bones begin to rapidly increase in size, and mold themselves into the various structures of the entity. When this process is completed, SCP-XXXX will become fully manifested. After this process, a 5 minute period is established purely for observation, as to decide whether or not it is safe to interact with the entity.
It is only theoretical, but if SCP-XXXX is mentioned in an open area, like a plain or field, the entity could grow so large it could crush the planet under its weight. This comes after several tests with onsite storage on various different sites. All testing to the limits of SCP-XXXX's anomalous abilities have been halted due to multiple containment breaches and repairs on several sites due to testing SCP-XXXX's abilities. While this anomalous ability may be concerning, it is only one of the many abilities of SCP-XXXX. Though, it is the most prominent, and most dangerous. Other anomalous effects of SCP-XXXX include the psychological urge to avert one's gaze of SCP-XXXX, random power failure of electronic monitoring, compulsive urges to mention the entity's name, or spread it to others, the attraction to open spaces, claustrophobia, and if extended contact occurs, hyperactivity, and summoning of smaller, aggressive entities from SCP-XXXX. These entities have been deemed SCP-XXXX-1. These entities are manifested from SCP-XXXX directly through a process of budding. According to SCP-XXXX, this process is immensely painful. Instances of SCP-XXXX-1 are to be terminated on sight.
SCP-XXXX was discovered by the foundation through informants investigating a meteorite that was relatively large, and gave off a weird signal. Upon discovery of the meteorite, it wasn't a meteorite at all. It was a tablet made of an unknown and durable metal alloy. Written upon it was what appeared to be glyphs. Whether or not these glyphs were used by another civilization outside of the solar system was unknown. However, there were traces of dead organic matter in the crevices of the tablet, along with many different traces of planetary metals. Upon deciphering of the tablet using SCP-███, it laid out an alphabet, galactic coordinates, and phrases, roughly translated to the following: "Do not mention the name." "Our home has been destroyed." "[DATA EXPUNGED]"
The first phrase seems to be referring to the third, which is the name of the entity. The second phrase is off by a degree, though it is currently the most accepted translation. When these phrases are mentioned to SCP-XXXX, other than its name, it often displays signs of distress, ceasing all contact with personnel for the remainder of its manifestation. It refuses answers to these sorts of questions, including questions surrounding its origin, and its intentions.
