'So far, existing containment arrangements have kept XXXX inhabited within a single host for the longest time recorded so far, at 3 weeks, 5 days, roughly. Almost a week and 3 days longer than the previous arrangement.'
This SCP was created from several revisions of the same concept – a seemingly non-material, vocal-reliant parasitoid that feeds off of the emotional energy of hosts, amplifying their inner thoughts, emotions and psychological state to a hundred-fold, and then emitted through vocalisations of extreme amplitude and loudness.
The sheer amount of stress caused by XXXX onto a host would cause immense amounts of pain, cells to enter a sort of ‘frenzy’ - deconstructing and reconstructing themselves, creating ‘warping’, alongside aggressive gangrene outbursts. The host would begin changing forms rapidly, before cells begin to denature (due to the stress), and within (roughly) 6 days and 23 hours, the host would enter its final stages of decomposition, and die. XXXX is able to keep the host somewhat animated in order to continue vocalising, however.
The primary ability of XXXX was the ability to transmit itself and/or its anomalous effects through perpetual, and often extremely loud vocalisations. The vocalisations would exponentially increase in volume after its host is deceased, in order to ensure it found a new host to feed on. The vocalisations would carry their affects with equal severity through both real-life and recordings (unless heavily altered.)
The combination of both the extreme induced stress, and the vocalisations damaging the hosts own body means that it undertakes extremely high amounts of pain, almost perpetually.
This SCP is singular, and so can only inhabit a single host at a time. However, its vocalisations can ‘spread’ the stress of the host, causing those who hear any sort of vocal emission from XXXX to be affected by the same symptoms that the current host is suffering from.
Another core idea was how the Foundation had written two revisions of its containment – the first included complicated protocol, which demanded that, before a host was to die, a new host was introduced to XXXX, stopping the SCP from ever increasing in volume to such a devastating extent. However, the Foundation found something ominous in its monitoring of XXXX over time – the SCP’s anomalous effects were amplifying in tremendous extremity – almost multiples. Hosts were beginning to warp much more severely, and form into much less biologically typical ‘humans’. Vocalisations were starting to sound more inhuman. This raised huge concern.
Although most of the Foundations findings on these signs were redacted, this forced the (then) containment brief to be decommissioned, and shifted the containment priority to keeping XXXX in the same host.
Although the foundation quickly discovered it was hard to elongate a hosts life beyond the fixed lifespan they found, they instead shifted to containing the maximum noise levels that XXXX could emit, as well as the host and XXXX itself by extension.
A new containment brief was swiftly written up – to contain XXXX within a single host, even after dying, and finding the limits of its vocal amplification. It was surmised by a panel (?) within the foundation that, due to XXXX’s reliance on organic material, there had to be a limit.
An extremely complicated, fixed containment chamber was created – a giant anechoic chamber, and additional ‘silence inducer’.
Here’s a direct sample of the specifications from my last draft.
//'XXXX must be contained within a 11' x 10' x 9' (v = 990 cu. ft.) fiberglass-based Anechoic Chamber, with a surface area of at least 598 sq. ft, with appropriately fitted graphene-reinforced wedge absorbers and additional triple-layer suspended flooring. The room must always retain a maximal background noise level of -27.2dB.
[UPDATED] Outer chamber layers must consist of at least 92.3% of Graphene or a similar allotrope carbon material, and measure to at least 12.1 meters thick, with a structural durability rating of AA+ (assessed by a designed containment specialist.) Any signs of structural degradation detected must be remedied immediately.
External audio spill, regardless of how minor, must be neutralised immediately by a designated containment technician. Any sort of recording device that could have potentially captured said spill must be destroyed immediately, and any files that potentially contain recordings of the spill must be deleted permanently.
[UPDATED] A device capable of high-capability, active noise cancellation and silence induction must be administered and installed both on the inside and outside perimeter of the Containment chamber, encompassing all identified emission zones and able to adapt to and neutralise abnormal sound emission beyond the peak recorded amplitude if possible – being 616.132…dB (as of 12/03/2018) (SilenCiLL III rev. 19 currently in commission)'//
The final core concept – the essential twist, will be revealed in one particular incident log – the first and only captured, coherent conversation between Personnel and XXXX. The report talks of XXXX allegedly reanimating the host during transmission, and talking about the struggles of the same man it had inhabited. It talks of how much the man suffered, and how the foundation treated him unfairly, (as a D class personnel) It was as if the deceased D class was talking through the SCP. It harboured intense anger and loathing for the foundation – in the D classes’ place.
All the things discussed by the SCP were proven to be factual in regards to the deceased personnel’s life.
The implications for the above are, to put bluntly, insane. XXXX tries to allow the host to vent all its emotions through a period of intense release – however, it has bloated itself in excess due to the amount of stress and tragedy it exposed itself to through the sheer multitude of successive hosts, and now, it kills the host in the process. It undertakes the emotions of the host, only to cause it to break down and kill the host in in such an agonising, long-winded way.
The SCP surely expresses disdain in being trapped in such a perpetual cycle. It is doubtful that it can save itself – like a simple organism, it can only carry on transmitting to new hosts. That is its only function.
