Multiple EIT1 snapshots of SCP-5XXX
Special Containment Procedures:
SCP-5XXX is contained in two (2) conjoined sections of Area-47 designated as Alpha-One and Theta-Zero on the northeast side of the facility.2 Sections Theta-Zero and Alpha-One are both TEMPEST certified shelters and each incorporates an embedded Grade-V lead-lined faraday cage. Section Alpha-One is the primary testing center for all research and experiments conducted on SCP-5XXX. Section Theta-Zero is a personnel lounge fitted with a one (1) meter thick lead-based glass window pane that bisects the room from the floor to the ceiling, so that SCP-5XXX may safely make scheduled visits with authorized staff to prevent it from feeling isolated.
- SCP-5XXX may only visit with authorized personnel on the grounds that “Procedure 731/Nekoma” is thoroughly performed daily and after all research sessions by Dr. Zhivago and his “Unit 731” staff.3 This protocol is required even if testing has not been performed. (See Addendum 5XXX-V/A: Procedure-731/Nekoma)
In order to protect Area-47’s staff against SCP-5XXX’s calamitous effects and safeguard the integrity of SCP-5XXX’s tranquil essence the following precautions must enforced:
- Every six (6) hours, one (1) Class C or Class E member of Area-47 will establish contact with SCP-5XXX to ensure it does not slip into a state of loneliness.
- SCP-5XXX will be assigned one (1) service dog to accompany it at all times for companionship. The animal is to be immediately replaced if lost or deceased.
- A team of six (6) full-time psychotherapists will rotate shifts to continuously provide SCP-5XXX with sincere social interaction. This team will also monitor SCP-5XXX for any changes in demeanor and present outlook towards its mission.
___The O5 Command and SCP-5XXX have an active working agreement so that as long as SCP-5XXX assists with various research assignments and expeditions, the Foundation will mitigate the side effects and irregularities caused by an extrinsic contagion affecting it as well as explore ways to assist it in finding its way back to its place of origin.4 (See Addendum 5XXX-IV/A: Expedition-Report-Log-5XXX-Φ-Tiānshén for all recorded Foundation expeditions.)
While undergoing testing and research of any type, SCP-5XXX will be sealed inside section Alpha-One. Containment procedures during testing are as follows in the case SCP-5XXX is noncooperative or makes any attempt to escape:
- The central A.I. “RAIJIN” is responsible for charging the main internal neodymium-doped phosphate glass laser grid to 75 YG (Yotta-Joules). An optical gyroscope will then establish an orbital path of the laser to surround SCP-5XXX.
- The auxiliary A.I. “EXHO” is assigned to priming the secondary external ytterbium-doped optical fiber laser grid to a nominal 34 ZG (Zetta-Joules). Gas-bearing gyroscopes will be responsible for keeping the external laser grid accurately trained on calculated weak points in the internal laser grid.
- In conjunction, these Class IV lasers will effectively seal SCP-5XXX in a controlled working area.
- Once testing has been concluded, staff will transport SCP-5XXX to the operating table where "Procedure 731/Nekoma" will be performed.5
- In cases of rare occurrence if SCP-5XXX overpowers the binary laser grid and should ever breach initial containment, the Area-47 emergency failsafe "Protocol Asura Rising" shall commence automatically.
Description:
Location:
SCP-5XXX is located in Area-47, approximately six-hundred forty-three (643) miles off the southwestern coast of Zanzibar, Tanzania. Area-47 is a subaquatic humanoid research facility roughly one-thousand three-hundred nineteen (1,319) miles below the surface of the Indian Ocean near the Mozambique channel. Area-47 was initially constructed for in-depth research of SCP-████. Following the neutralization of SCP-████ the site has been upgraded and recommissioned for its new mission with SCP-5XXX.
Physical Features:
Evaluation sample of SCP-5XXX's superfluid.7
- SCP-5XXX is a sentient humanoid entity resembling a human female measuring one-point-six-three (1.63) meters in height and at rest8 weighs forty-seven (47) kg.
- The entity’s body is primarily composed of an unidentifiable9 translucent supercritical superfluid (SCSF).10
- The subject emits strong levels of Cherenkov radiation, giving off a soft blue luminescence measured at ranges of ten (10) nm to four-hundred fifty (450) nm in wavelength and all emitted photons steadily produce █.██ eV of energy.11
- SCP-5XXX can apparently suppress its hazardous levels of extreme ultraviolet radiation (XUV) seemingly at will by increasing or decreasing the density of the superfluid that shapes its body mass.12 The subject seems to suppress the radiation when it is in the presence of an organism it does not wish harm.
Metaphysical Characteristics:
___The initial Area-47 staff perished due to succumbing to acute radiation syndrome (ARS). The discovery of this incident was brought to the Foundation's attention when an off-site overwatch post reported that the original Area-47 Director, Jaime Marlowe, missed her daily check-in sequence. The overwatch post had also reported alarms being triggered by unsafe radiation levels.13 Once a skeleton crew response team was assembled and had made direct contact with SCP-5XXX, technicians on the crew noticed radiations levels plummeted to 0.01 mSv (millisieverts).
Biohazard:
- Type IV
SCP-5XXX will neurologically alter an individual’s cerebellum to call it “Deviraya”, which prevents SCP-5XXX from being called by its official SCP item number designation by staff.14
___Through rigorous testing, Unit 731 has concluded that this malignant side effect occurs only when SCP-5XXX is put in isolation. A Unit 731 after-action report details SCP-5XXX becoming physically and psychologically unstable and achieves spontaneous fission while beginning to radiate extremely high levels of radiation. Geiger counter readings indicate SCP-5XXX enters a hypercritical state, triggering a strong nuclear chain reaction. Numerous quantum computer simulations of this event hint at a potential “pair-instability hypernova”15 incident. (See Addendum 5XXX-VII/A: Containment-Log-5XXX-1/A)
___SCP-5XXX at times exhibits a somber behavior and will seek out conversation with anyone who will make time for a discussion. Researchers have observed that SCP-5XXX instills a pleasant sensation of feeling free of harm while nearby.16Many individuals that have interacted with SCP-5XXX proclaimed that it gave them a sense of security and emotional warmth.17 SCP-5XXX also seems to be able to talk to staff members in any language, closely recreating their dialect and intonation. Fluency in languages seems to come natural and it seems to be aware of customs and courtesies for human interaction. Its demeanor resembles that of a young adult as to how it expresses itself or engages with others.
___While undergoing destructive testing to determine if SCP-5XXX is capable of being neutralized, researchers have recorded that when it is physically assaulted it can pass through solid matter to escape. (See Addendum 5XXX-VI/A: Incident-Log-5XXX-RED/9)
___During aptitude testing the entity has exhibited inherent omniscience and omnipotent abilities, both of which are heavily restricted. SCP-5XXX has sensed that this restriction appears to be caused by the presence of an unrecognized entity in our reality. This unidentified foreign abstract seems to be slowly infecting SCP-5XXX’s body and is gradually corrupting its psychological state.18 (See Addendum 5XXX-IX/A: Aptitude-Test-Log-1A)
___SCP-5XXX has informed researchers that it is from a concurrent sister reality but was allegedly pulled into our reality when an unknown entity triggered the rare formation of a unique magnetar causing a “Type II Superluminous Super-Nova Remnant” (Type II - SLSNe/R) event. All of its “deity-like” abilities are profoundly inhibited during most circumstances. (See Addendum 5XXX-II/A: Malphas-8 Covenant)
Starbreaker Incident:
___Due to the nature and composition of SCP-5XXX's atomic structure, it becomes extremely unstable once every twenty (20) years as its body stores cosmic background radiation energy over time. Researchers have learned that SCP-5XXX will require a safe location to purge this excess energy. Once every two (2) decades the Foundation will give SCP-5XXX coordinates to a nearby star system one million (1,000,000) light-years away from Earth to await its inevitable purge event. Foundation asteroseismologists have recorded it producing from thirty-six (36) to one-hundred eighty-seven (187) starquakes per minute during this event.19 During this event, with SCP-5XXX at the epicenter, the area of effect observed reaches a diameter of five hundred thousand (500,000) light-years across. Due to the strength of this purge event nearby galaxies or fragmented star systems are immediately overwhelmed and annihilated.
