Special Containment Procedures: Permits for the excavation of land upwards of 0.75 kilometers beneath the greater metropolitan area of Scranton, Pennsylvania are to be denied without direct word otherwise from the O5 Council, with a reasonable explanation being devised or appropriated as per standard Foundation disinformation protocol. Individuals or organizations attempting to unlawfully penetrate ground in the area are to be detained and thoroughly questioned, followed by amnesticization in the case of above-Veil actors.
Recording devices planted within SCP-7379 are to be monitored at all times. Given any indication of abnormal activity from the area of SCP-7379, all major Foundation sites are to be put on temporary lockdown until signs cease — typically, this occurs upon the neutralization of the target in the event of an SCP-7379 activation. Upon cessation of the event, storage room A-76 is to be unlocked and checked for signs of communication from the facility’s operators.
Use and maintenance of Site-7379 by its operators is not to be contested by Foundation command at the Site or executive level under any circumstances. In all other respects, the Foundation is to allow the facility to operate without interference. Attempts to open additional inquiry into, experiment upon, or otherwise engage with the inner workings of SCP-7379’s Central Reactor Chamber beyond simple observation is prohibited.

Description: SCP-7379 is the SCRANTON1 Reality Anchor, a massive subterranean nominally Foundation-operated reality stabilization device located beneath Scranton, Pennsylvania. Structurally, it resembles a greatly enlarged fusion plant with thirteen (13) reactors and no smokestacks or other visible means of releasing emissions. Presumably as a resultant externality of its operating function, localized reality within an approximately fifty-kilometer radius of SCP-7379 is constantly stabilized at a Hume concentration of ~10,000ξ, roughly 100 times greater than standard levels. As such, the anomalous alteration of reality in any way is extremely difficult in and around the area of SCP-7379 and the entire city is effectively immune to any form of ontokinetic incursion or remote alteration.
Upon activation, SCP-7379 is capable of drastically raising the localized Hume coefficient of almost any remote location on Earth. The exact mechanisms by which SCP-7379 accomplishes this task is unknown, as its internal apparatus are poorly understood by the Foundation at present2. After activation events, SCP-7379 displays an inability to reactivate for a period of 8-12 years. The presumed reason for this pause is to enable the recharge of the apparatus used by SCP-7379 to perform the stabilization of local reality, which are, as previously mentioned, not precisely known at this time.

Above: Exit Lambda from Site-7379.
SCP-7379 typically initiates the process of activation immediately prior to the manifestation or containment breach of one or more high-potency reality-bending entities. Within minutes of the manifestation or breach in question, SCP-7379 will have fully readied itself for activation and will deploy its primary anomalous property to raise the Hume quotient of the anomaly’s local area, neutralizing its ontokinetic capacity with overwhelming suppressive force. The targets of SCP-7379 activations are not chosen by Foundation high command nor known in advance of activation, however often coincide with those entities considered high-priority threats by the Foundation at the time of the event. The nature of SCP-7379 activation events and their ostensible prioritization would seem to indicate that the facility or its operators are in possession of some form of predictive algorithm or precognitive anomaly and can foretell the rise of hostile ontokinetic entities with a considerable degree of accuracy; further research into this is ongoing.
Around the area of SCP-7379 lies Subterranean Site-7379, a Foundation containment facility built contemporaneously to SCP-7379 itself. Site-7379 serves two purposes: maintenance, observation, and control of SCP-7379, and weaponized use of SCP-7379’s passive anomalous property to contain catastrophically high-threat reality-altering anomalies by suppressing their ontokinetic capability. Site-7379 is composed of hundreds of disparate wings and chambers interconnected by giant, labyrinthine3 tunnels and caverns equipped with an internal subway system for easy transport. In all, the area of underground which Site-7379 occupies is approximately 40 kilometers in length and 26 kilometers in depth.

As of 1972, approximately thirteen thousand (13,000) Scranton Reality Anchors, Anderson Anchors4, and Lang-Scranton Stabilizers5 have manifested around and beneath SCP-7379 in a state of inexplicable and irreparable malfunction. Additionally, since the 1972 incident6, the Central Reactor Chamber of SCP-7379 has held an indeterminately immense number of contained and semi-contained anomalous objects in seemingly haphazard configuration. Consult Addendum 7379.1 for more information.
As of 22 August 1991, the O5 Council has issued an executive order stating that these objects are not to be manipulated, rearranged, or removed under any circumstances as to prevent accidental interference with the function of SCP-7379 by Foundation personnel.
History: Construction of SCP-7379 and Site-7379 was first ordered by Dr. Robert Scranton of the Department of Ontokinetics in October of 1963, following a report from his department that urged the necessity that the Foundation construct a device for neutralization of large-scale reality-altering threats. Scranton, Pennsylvania was chosen as the preferred location to construct SCP-7379 due to its orientation on a naturally-occuring point of leyline overlap corresponding to high average Hume rates. In the ensuing decade, preparation and construction began, with a large area being cleared out approximately 2 kilometers beneath the city. A scaffolding for the structure was constructed soon after, with external walls, tunnels across the in-construction Site-7379, and the boundaries of rooms for the site being excavated. The structure’s outer shell was completed as of 1969, with internal installations — including Site-7379 control rooms and offices, a subway system for exit, entrance, and internal traversal, and the then-empty Central Reactor Chamber of SCP-7379 — finishing construction in 1971.

Above: Ontological stabilizer undergoing initial inspection at Site-7379.
During an intermittent period of schematic development in the Spring of 1972, the main facility would not be accessed for several months. Upon reentry, it was discovered that that the interior of the facility had been entirely redeveloped by unknown means, with an entire internal geography and array of anomalous mechanisms having manifested without the recorded approval or knowledge of any Foundation-sanctioned authority.

Above: Placard at Entrance Alpha of Site-7379.
The manifested interior and associated machinery, though largely impractical or counter-intuitive for human use, is indeed believed to have been placed with deliberation, as many foreign objects, such as those inserted within the Central Reactor Chamber during the incident, have provided ontological anchoring functionality and enable the current use of SCP-7379. It is, as such, believed that construction of SCP-7379 and its associated site was completed — unaccordingly and in contradiction to extant plans for the facility, though still with intention — by an unsanctioned party during the break from construction, and that this party was aware of the facility's intended purpose and attempted to aid construction to this end on its own terms.
Following the incident in 1972, several uniform placards displaying the text “Department of Abnormalities”7 and an unidentified glyph somewhat resembling the standard Foundation insignia manifested at the entrance and exit gates of Site-7379's tunnel system.
Addendum 7379.1: Recorded Contents of the Central Reactor Chamber
The following is an incomprehensive list of anomalous objects observed to be in containment in SCP-7379’s Central Reactor Chamber following the manifestation incident in Spring of 1972. Objects are typically found stored in variably-euclidean and sometimes misshapen containment chambers connected to one another via conveyor belts, pipelines, pulleys, plexiglass tubes, slides, chutes, robotic arms, miniature train tracks, and other increasingly odd and seemingly inefficient means of transport strewn across the chamber. Upon each chamber hangs a metal placard bearing a colloquial or poetic identifier of unknown meaning, as well as an insignia somewhat resembling that of the Foundation.
