Special Containment Procedures
If a manifestation of SCP-1861 is reported, Task Force agents from the nearest Foundation Outpost are to reroute traffic away from the affected area and prevent civilian interaction with SCP-1861-B instances. A separate team must be deployed with the specific task of locating and preventing access to SCP-1861-A. As SCP-1861-B instances cannot be destroyed with brute force, diplomatic means of preventing civilian abduction should be undertaken if at all possible. Foundation Misinformation agents positioned in local news sources and weather monitoring sites are to attribute SCP-1861 to irregularities in air pressure and large quantities of dust present in storm water. Civilians who enter SCP-1861-A are to be declared legally dead, with causes of death attributed to common inclement weather accidents.
Description
SCP-1861 is an anomalous meteorological phenomenon characterized by heavy precipitation and fog composed of saltwater, human blood, and human cerebrospinal fluid. SCP-1861 manifestations are unpredictable, appearing spontaneously and with no regard to an affected area's natural climate and weather patterns. Manifestations typically occur once every three to six months and have been recorded occurring in numerous regions across the world. Historical records have confirmed that SCP-1861 has existed since as early as the year 1916. The size of the area covered by SCP-1861 varies from instance to instance, with the largest recorded affected area measuring approximately 5,000 km2. Aside from its manifestation, composition, and apparent connection to SCP-1861-A, SCP-1861 displays no additional extranormal properties.
SCP-1861-A is a single underwater marine vessel that closely resembles B-class boats used by the British Royal Navy in World War I. During each SCP-1861 manifestation, SCP-1861-A will attempt to surface in a body of water that is large enough to contain its full mass. Both natural and manmade bodies of water have hosted manifestations of SCP-1861-A. If no body of water large enough to contain the entirety of SCP-1861-A is present, SCP-1861-A will surface in any collection of water with a surface area large enough to encompass its conning tower and topmost platform, even if the collection of water in question is only several inches deep.
SCP-1861-B are humanoid entities that emerge from SCP-1861-A during SCP-1861 phenomenon. SCP-1861-B are dressed in full body suits resembling deep sea diving gear, although with no discernable source of air supply. Instances of SCP-1861 are uniform in size and possess speed and strength typical of an adult human male. Although most instances are sapient and capable of speech, approximately 9% possess limited intelligence and are only sentient. Instances that are incapable of verbal communication have been recorded making vocalizations similar to to the cries of domestic felines, canines, and infant humans. The diving gear worn by SCP-1861-B instances is anomalously durable and cannot be removed except by the instance presently wearing it. If an instance of SCP-1861-B encounters a human subject, it will attempt to persuade the subject into entering SCP-1861-A, claiming that this action would be in the subject's best interest. Subjects who refuse may or may not be forcefully taken to SCP-1861-A, depending on the temperament of the SCP-1861-B instance.
Human subjects lured into entering SCP-1861-A will reemerge during subsequent SCP-1861 manifestations as SCP-1861-B instances. If an SCP-1861-B instance is taken outside SCP-1861's area of effect, it will begin to experience accelerated fatigue and lose consciousness, becoming completely inert until reintroduced into SCP-1861. After a manifestation of SCP-1861 has ended, SCP-1861-A will disappear along with any remaining instances of SCP-1861-B; additionally, blood, cerebrospinal fluid, and saltwater left behind by SCP-1861 will instantly convert to regular rainwater.
