Item:
SCP-5000. "The Siblings of Connection."
Object Class:
SCP-5000-1 = Euclid (pending Thaumiel).
SCP-5000-2 = Euclid.
SCP-5000-3 = Keter.
Special Containment Procedures:
SCP-5000-1 is to be kept in a standard human containment cell with one (1) standard computer connected to a closed and monitored network, this computer is to be cycled out every two weeks and inspected by a certified technician for damage.
Additionally, SCP-5000-1 is to be provided with one (1) blank USB Memory Stick of up to 16GB every 72 hours as a form of nutrition.
SCP-5000-2 is to be kept in a standard human containment cell, with access to a standard size garden pot as well as gardening supplies such as commercial fertilizer as well as plastic tools that are to be examined on a weekly basis to prevent self-injury by the instance.
Furthermore, SCP-5000-2 is to be granted one (1) commercial grade package of Taraxacum1 seeds at least once a month.
SCP-5000-3 is to be kept in a 5m by 5m cell that is separate from any personnel or civilians by atleast 10m. Furthermore, SCP-5000-3 is to only be interacted with or interviewed by an autonomous robot for the safety of all personnel. In an emergency situation, SCP-5000-3 is to be rendered unconscious and secured with a blindfold and gag to prevent interaction between personnel and the entity.
Once a week SCP-5000-3 is to be allowed to interact with one D-Class subject that is due to be terminated within the next 24hrs.
Description:
SCP-5000-1
SCP-5000-1 appears to be a middle-aged Eastern-European male approximately 1.63m (5'4") in height. The entity appears to suffer from mild malnutrition, and has slate grey mottled skin.
Attached to the entities spine from the C4 vertebrae to the L1 vertebrae appears to be a device of an unknown origin consisting of materials that are consistent with ██████. Near the base of the neck are several female-type ports consistent with that of a computer, these connectors include one (1) USB 2.0 and 3.0 port, two (2) HDMI ports, one (1) VGA and one (1) DE-9 serial port, two (2) PS/2 ports and one (1) AUX port [3.5mm version].
This device appears to be the only way for SCP-5000-1 to gain sustenance as all nutritional substances will not be absorbed or used by its body, the reason for this is as yet ongoing but is attributed to the device which may be preventing natural digestion processes from occurring.
It has been observed that should the entity stay in prolonged connection with a device approximately 5 hours to 1 month depending on the complexity and sensitivity of the device, the entity will inadvertently damage the components or coded software of the device.
SCP-5000-2
SCP-5000-2 appears to be an Eastern-European female assumed to be in her mid to late 20's, they are approximately 1.68m (5'6") in height.
The palms and pads of SCP-5000-2's hands and feet are permanently stained a bright green colour, the cause of this discolouration appears to be due to high amounts of Chlorophyll present inside SCP-5000-2's epidermal cells, this discolouration is permanent and also serves as the entity's way to "connect" to plant matter.
In a similar fashion to SCP-5000-1, SCP-5000-2 does not gain nutrients from standard food sources but instead will perform a crude form of symbiosis on any plant matter it can access however it appears that this process will inevitably kill off the plant as a large amount of its sugars and minerals are drained from it in the process.
SCP-5000-2 possesses the ability to induce accelerated growth in spouts and juvenile plant matter meaning that a plant that would take a year or more to mature instead may mature in a matter of days or weeks.
SCP-5000-3
SCP-5000-3 appears to be a middle-aged Eastern-European male slightly older than SCP-5000-1 approximately 1.91m (6'3") in height.
Inexplicably, the entity will always be wearing a cleanly pressed 3-piece suit, usually the colour red however instances of the suit being other colours (blue or green) have occurred, despite no access to such attire.
In SCP-5000-3's possession is a small silver necklace around 3cm wide depicting the common theatre masks, any subject that attempts to hold or wear this artefact reports that it began to heat up to extreme temperatures (despite temperature sensors showing no sign of a change) and having an extreme desire to remove or destroy the artefact, this necklace has been dubbed SCP-5000-3/1.
SCP-5000-3 appears to have what some may say "natural charisma and charm" however, it is theorised to be a latent psychological effect caused by the entity, this effect causes subjects exposed to SCP-5000-3 to be more open to suggestions by the entity however, any particularly strong-willed personnel such as Dr. A Clef appear to be resilient to the entity's "wiles and charms".
As with both SCP-5000-1 and -2, SCP-5000-3 cannot gain sustenance from normal means and instead appears to perform a parasitic action upon any subject the entity comes in contact with, although the effects of SCP-5000-3 are not immediately apparent, any prolonged exposure to the entity will begin to show apparent signs of deterioration of a subjects physical and mental health with post-mortems performed on D-Class personnel exposed to SCP-5000-3 showing a significant degradation of the subjects internal organs and brain structure that may result in long-term or permanent illness and neuro-degenerative diseases.
Addendum 1:
Psychiatric and Physical evaluations of Dr.██████ conclude that he suffered a sudden anger-induced outburst likely caused by SCP-5000-3's anomalous effects. Dr. ██████ was put on observation for 2 weeks and was removed from SCP-5000-3's experimentation team.
Any further interviews and tests conducted on SCP-5000-3 are to be done either remotely or when the entity has been put under anaesthesia.
Addendum 2:
The proposition for possible Thaumiel class for SCP-5000-1 is under review by O5 administrators █████ and ████, [note from Dr ██████: "5000-1's ability to irreparably destroy and contain data devices may be an asset in possible containment or destruction of highly classified Foundation records should a breach occur."]
