Item #: SCP-031
Object Class: Keter
Special Containment Procedures: Collected, inactive samples of SCP-031-01 should be stored in Regulation-BH3 Petri dishes, and always handled with full biological hazard support. Samples should be collected from SCP-031-02 as needed for research of SCP-031-00, again with full biological hazard support. Any personnel exposed directly to living samples of SCP-031-01 should be made sterile and be routinely examined or made part of [DATA EXPUNGED].
SCP-031-02 should be left to suspend by its own devices within a cylindrical steel-mesh structure, measuring 2.5 m in diameter and 6 m tall. This structure is to be suspended 1 m from the floor, in a chamber measuring at least 10 m x 10 m x 10 m. Walkways should accommodate access to the top opening of the cylindrical structure, for feeding purposes. All access to SCP-031-02's chamber is to be strictly regulated, and to comply with full environmental biohazard protocol. Once weekly, SCP-031-02 is to be 'fed' a live human subject. Other organisms may be used for research purposes.
All instances of SCP-031-03 should be given fairly comfortable but separate accommodations as suitable for humans. Whilst living, no SCP-031-03 individuals should ever be in the same facility as SCP-031-02. Should any subjects start to show signs of physical or mental deterioration, they are to be quickly evaluated and terminated if deemed necessary. All deceased instances of SCP-031-03 should be given to SCP-031-02, but should not count towards its weekly meal.
Description SCP-031-01: SCP-031-01 are small worm-like parasitic organisms grown by SCP-031-03 within the live human hosts given to SCP-031-02. It seems SCP-031-02 uses the genetic material from its human hosts to create SCP-031-01 and replicate SCP-031-00. The human hosts are then kept alive to incubate SCP-031-01.
SCP-031-01 contains large amounts of the prion dubbed SCP-031-00. SCP-031-01's role seems to be to infect human hosts, finding its way to the testes or ovaries and then releasing large amounts of SCP-031-00, which infects the reproductive systems. SCP-031-01 dies shortly thereafter. SCP-031-01 cannot survive outside of SCP-031-02 or the human body.
Description SCP-031-02: SCP-031-02 is, at first glance, a large blood-colored pulsating pod or sac suspended aloft by a large mass of connected tendrils. SCP-031-02’s tendrils seem to contract instinctively, and draw any foreign objects within its mass towards the main sac in the center to be “processed”. Any current “fodder” SCP-031-03 may be processing at the time is usually mostly visible, held to the center pod by an appropriate number of tendrils. From the main pod hang four more distinct hose-like tendrils, which constantly drip a reddish-brown liquid. This liquid is similar to human blood, but contains an unidentified enzyme which seems to cause mild amnesia. Swimming within this substance is a high density of SCP-031-01.
Except during initial formation and positioning, SCP-031-02 itself seems relatively inert, and seems to depend entirely on SCP-031-03 to find and introduce suitable hosts to its mass. This seems to be more for reproductive purposes than nutritional ones, as SCP-031-02 has been shown to be able to last years without food.
Description SCP-031-03: SCP-031-03 are the progeny of individuals infected by SCP-031-00 and SCP-031-01. For all intents and purposes, they are completely indistinguishable from normal humans. Individuals of SCP-031-03 seem to be drawn in SCP-031-02's direction if within 15 kilometers of its location. Seemingly, the older the individual, the more irresistible this urge becomes. Individuals actively kept from following this urge report high levels of unease.
Within a few days of being exposed to SCP-031-02, SCP-031-03 individuals start reporting frequent 'blackouts' and lost time. Filmed individuals are noticed merely standing still during these times if occurring during the day. Nightly, these individuals are prone to somnambulism.
Two (2) or three (3) times a month, however, these individuals seem compelled to return to SCP-031-02 and drink from one of its four hose-like tendrils. Once full, the individuals will generally try to quickly find and surprise a victim, favoring lone subjects, especially those sleeping or easily incapacitated. The SCP-031-03 individuals will seize their subjects and then regurgitate some of their stomach contents into their victim’s mouth, infecting them with SCP-031-01. Their subjects quickly fall asleep, and never seem to recall the attack, probably due to the amnesiac properties of the regurgitated fluid. Sometimes, SCP-031-03 may bring its incapacitated victims to SCP-031-02 as 'fodder' to be used in preparation of further SCP-031-01. SCP-031-03 never seem to remember these nightly experiences during the first few months. With time, however, it seems these activities are undertaken while completely lucid and self-aware.
Of note, SCP-031-03 individuals which have not been exposed to SCP-031-02 by age 30 seem to become intensely preoccupied with searching for another SCP-031-03 infected individual. This is often expressed as a desire to "find their soulmate", "find their place in the world", or "find a reason to live". These individuals are given to bouts of wanderlust, and often pour all of their available resources into traveling as extensively as possible. Once they find another SCP-031-03 individual, the two undergo a transformative process at the end of which they become a new, small instance of SCP-031-02. No instances of SCP-031-03 have been observed to live past age 35.
Addendum-SCP-031-1: Interestingly, it seems SCP-031-03 individuals are immune to the effects of SCP-031-01. SCP-031-03 individuals seem to be capable of breeding with uninfected individuals to produce completely normal humans. - Dr. █████
Addendum-SCP-031-2: Could the substance secreted by SCP-031-02 be refined for use as an amnesiac? This could be a great asset to the foundation. - Dr. Dougan
Addendum-SCP-031-3: The average life-span of SCP-031-03 individuals after being exposed to SCP-031-02 seems to be no longer than three years. Still, a single individual infects an average of 30 people a year, 90 throughout its run… - Dr. █████
