Special Containment Procedures: Two copies of instructions on how to conduct SCP-XXXX are to be contained at Deep-Sea Site-72 and Area-34. Foundation webcrawler I/O NEPTRON is to search online forums, video hosting sites and social media for posts regarding SCP-XXXX and archive them prior to taking them down.

The Foundation is to disseminate disinformation on previous instances of SCP-XXXX being executed, discrediting them by claiming that SCP-XXXX-A and -B were in fact paranoia-induced hallucinations.

Deep-Sea Site-72 is currently in the process of constructing biocontainment chambers designed for SCP-XXXX-B instances, in the event that a means to contain them is devised.

Update 15/03/26: A security perimeter of 50m has been established around SCP-XXXX-C. Civilian ships and planes are to be redirected with the cover story of a study being conducted on an endangered marine species. Regular expeditions are to be done into SCP-XXXX-C to catalogue and, if possible, cull the population of SCP-XXXX-B instances within the area. Research is to be done into potential means to neutralize SCP-XXXX-C.

Description: SCP-XXXX is a thaumaturgical ritual that allows for specific sections of baseline reality to become entangled with another reality, SCP-XXXX-A. SCP-XXXX requires multiple requisites in order to be properly executed, including (but not limited to):

  • A large, deep body of water, in such a way that the bottom can't be seen.
  • A submersible vehicle vaguely spherical in shape.
  • A sufficient depth beneath sea level (The exact depth is unknown, but estimated to be around 920 meters, although there have been previous examples of SCP-XXXX at lower depths).

SCP-XXXX-A is an alternate reality accessed via SCP-XXXX, which is comprised entirely of saltwater, believed to be an ocean of sorts. Previous executions of SCP-XXXX have failed to reveal a seafloor or surface in SCP-XXXX-A, but the existence of SCP-XXXX-B seems to also point towards the existence of both of these. There is no visible light within SCP-XXXX-A. Due to the parameters of SCP-XXXX, SCP-XXXX-A can not be fully explored, although there are working theories involving the use of SRAs in order to remove certain sections of SCP-XXXX's boundaries.

SCP-XXXX-B is a general term used to refer to any living organisms that inhabit SCP-XXXX-A. A majority of SCP-XXXX-B instances spotted to date have been predatory in nature, although few have attempted to attack personnel. Most personnel viewing SCP-XXXX-B instances report feeling a sense of dread and unease, although it is unknown if this is a natural response or a shared anomalous property of instances.
