A moon jellyfish, Aurelia aurita, appears to resemble an SCP-XXXX-1 specimen.

Item #: SCP-2610

Object Class: Safe

Special Containment Procedure: SCP-XXXX is currently contained in a 10m³ vacuum chamber made of 40mm fiber glass. For safety purposes, the object must be contained in a scratch resistant containment chamber to prevent any structural contamination. All procedures that require access to SCP-XXXX's containment must be approved and supervised by at least two (2) Level 4 Personnel. Maintenance and experimentation must be performed only by Class D personnel, and all should be terminated after the procedure. SCP-XXXX-1, which includes test subjects, must be isolated and contained to a separate facility with the same conditions. Strictly under no circumstances be SCP-XXXX and SCP-XXXX-1 exposed to open air, heat shock, electromagnetic currents, radiation, corrosive substances, and other such severe stress conditions, that might trigger an SCP-XXXX-2 growth event.

In case of an SCP-XXXX-2 event, the primary containment facility (respectively the vacuum chamber) must be locked down immediately, followed by personnel evacuation of the secondary containment area. Ventilation systems should filter air coming from the primary and secondary containments, and be vacuumed for decontamination. This emergency procedure will last for the next 48 hours, to ensure that all SCP-XXXX-1 and SCP-XXXX-2 contaminants be neutralized. After this countermeasure, all personnel within the facility must be subjected to physical and psychological evaluation for possible SCP-XXXX-3 symptoms.

Description: SCP-XXXX is a hexagonal object approximately 0.4m³ in size, seems to be made of wood, but the exact material has not yet been distinguished. Upon close contact to SCP-XXXX, it is observed that matter somehow performs an unidentified form of macromolecular modification, referred to as "crystallographic contamination". The effect (which is simplified as a contamination) resembles a normal crystal growth, but unlike the formation of perfect and real crystals, it transforms the material into a liquid crystalline tissue, aesthetically similar to mesoglea (the gelatinous substance found to the jellyfish family), with partial optical transparency. However, despite being compared to a jellyfish tissue, this tissue seems to be rigid and compact, while simultaneously expressing some degree of elasticity and plasticity. Analysis of samples taken from the contaminants (designated as SCP-XXXX-1) proves that its indeed a living tissue, that includes the presence cells. It is unknown if this is an undiscovered process of nonorganic abiosynthesis, as the anomaly requires further analysis.

SCP-XXXX, can contaminate all states of matter, whether its organic or inorganic, which is not limited to plasma and other high energy states, and could have different effects on each state. Observations shows that contamination to fluids are relatively slow, while moderate to solids. On the other hand, contamination on the plasma state occurs violently rapid, with additional consequences, such as the formation of real crystals, dendrites and mono crystalline whiskers. Further observations also shows that SCP-XXXX and SCP-XXXX-1 are both invulnerable to all severe stress conditions, such as at high temperatures, extremes in pH, gamma radiation, physical deformation, and even oxidative stress, primarily because of their somewhat unique and anomalous macromolecular morphology.

Addendum XXXX-1:
The following are conclusive observations that resulted to the successful containment of SCP-XXXX and its effects.

Although contamination from SCP-XXXX (this also include all secondhand contamination) could be airborne or requires any transport of matter, it can only occur on rough or defected surfaces, such as on leaves, rocks or unpolished wood, concrete or metal.

Similar to known crystal growth techniques, scratches or dents could act as nucleation sites. This suggests that the contamination (or crystallization) must have first generated a seed crystal, or a nucleus, that subsequently continues the process even in (or after) the absence of SCP-XXXX.

Introduction of foreign materials during the contamination could be another factor. The reaction reduces the total amount of time, and then followed by the consummation or fusion of the foreign materials into the main contaminant. Both materials are impossible to distinguish after this effect.

Despite their invulnerability to severe stress conditions, further exposure such conditions could trigger an spontaneous growth or biogenesis, referred to as SCP-XXXX-2 (this designation is applicable to the event and the resulting organisms). This effect will "birth" an unidentified and anomalous microorganism, later named [DATA EXPUNGED]. These microorganisms are also invulnerable, and observed to perform the same contamination upon contact to matter. Although they can multiply for [REDACTED], however, they eventually decay after 36 hours inside a vacuum.

Addendum XXXX-2 After 48 hours (or at least) of exposure to SCP-XXXX or SCP-XXXX-1, some personnel had reported to experience "phantom pain" sensations described as "painful but addictive". If this hallucinogenic effect continued for the next 16 hours, delusions and psychosis will follow. These personnel after 16 hours would now be classified as SCP-XXXX-3. The process of molecular modification is different after this case. They appear to look like luminescent bluish apparitions. Seeing this entities spreads the contamination.

Addendum XXXX-3 After Event XX, all research procedures regarding SCP-XXXX and SCP-XXXX-1 are now restricted, due to the discovered SCP-XXXX-3 effect, which is a severe cognitohazard.
