Several instances of SCP-2704 found in [REDACTED]

Item #: SCP-2704

Object Class: Euclid

Special Containment Procedures: All instances of SCP-2704 within Foundation custody are to be kept in storage containers located at storage hangar 19A and 19B. Infrasonic detection systems are to be placed within both storage units and kept operating at all times. If a sound at a frequency below 20 Hz is detected in either of these units, all personnel are to evacuate to Observation Site 19A, and are to remain there until the sound diminishes. Personnel are to monitor SCP-2704 during this time for any undocumented effects.

Instances of SCP-2704 discovered outside of Foundation custody are to be immediately reported. If said instances are located in a heavily visited or populated location, they are to be replaced by a 1:1 replica. This is necessary due to SCP-2704's importance in Costa Rican culture. Instances found in their original position, including instances which reside in the Finca 6 archaeological site, are not to be relocated. Implanted Foundation agents have acquired control over administration and security of this site. Infrasonic detection systems are to be kept within all security offices of Finca 6. If a sound at a frequency below 20 Hz is detected, any present pedestrians are to be evacuated to a distance of 92 meters from the premises.

All subjects affected by an activated instance of SCP-2704 are to be apprehended and questioned on their experience. Class A amnestic are to be administered to non-personnel subjects following the questioning.

Description: SCP-2704 is the collective designation given to an assortment of over three hundred petrospheres predominantly located in Costa Rica, which were initially discovered in the Diquis Delta during the 1930s. These spheres range in size from a few centimeters to over 2 meters in diameter, and weigh up to 16 metric tons.

The anomalous effects of SCP-2704 instances become activated in concordance with the position of celestial bodies in the night sky. Once two or more celestial bodies form specific geometric shapes or patterns above instances of SCP-2704, these instances will become activated. This occurs primarily with the planets and moons of our solar system. However, there have been incidents which may have involved celestial bodies outside the Milky Way galaxy. Each singular instance of SCP-2704 appears to be linked to a specific celestial pattern. It is also believed that the activation of SCP-2704 instances are dependent by their arrangement with one another, when located in their original position. Due to these requisites, it is currently impossible to predict when the majority of instances will become activated, due to the loss of their original organization during initial discovery. Studying the activation of these unorganized instances has not progressed the discovery of a pattern of activation.

Once any instance of SCP-2704 is activated, it will begin to emit a sound at a pitch of about 13 Hz, undetectable by the human ear. This hum has physical and psychological effects on all human beings within a 92-meter radius, and plays continuously for approximately 3 hours after activation. The means used to produce this sound remain unknown.

The following are the effects related with unorganized single sphere activation:

• After 30 minutes of exposure subjects experience mild migraines and discomfort.
• After 1 hour of exposure subjects experience increase in emotional unease and throbbing pain in the temples.
• After 2 hours of exposure migraines worsen, in some cases subjects become incapacitated due to pain. Subjects will begin to receive an influx of information. Complementing this information, subjects experience visual and auditory hallucinations. This activity lasts for approximately one hour. These episodes can cause loss of consciousness in those with a history of brain related medical complications. If these subjects are not removed from exposure radius, they may enter a coma.
• After 3+ hours of exposure, effects will slowly deteriorate. Subjects reportedly forget a large portion of information received.

Please refer to the Incident Log for further details concerning the effects of SCP-2704 and information received.


Initial discovery of SCP-2704

These spheres were originally found in clusters of up to twenty organized in geometric patterns. They are estimated to have been carved between 200 BC and 1600 CE. Details concerning the method used to sculpt and transport these spheres, as well as their original purpose, are unknown. This is due to the extinction of the indigenous culture of Diquis Delta following the Spanish conquest.

The anomalous properties of SCP-2704 were not discovered by the Foundation until 1947. Due to this, the majority of known instances have been damaged and/or re-positioned prior to Foundation involvement. These instances of SCP-2704 were relocated to public areas such as tourist locations, , government offices, parks and several museums. The majority of these instances have been replaced with exact replicas, and are now under Foundation custody in hangars 19A and 19B. However, there are SCP-2704 instances that retain their original position which remain undiscovered.

Known instances which retain their original position and order with one another are primarily located in the Finca 6 archaeological site. These instances of SCP-2704 are to remain in this original position to facilitate the observation of activation, discovery of patterns of activation, and investigation of the stones' possible purpose. Public access to these spheres has been scheduled and restricted to only occur during the day, in order to minimize possibility of pedestrian presence during a cluster activation. Since initial containment there has been two successfully recorded cluster activation.

For further details concerning effects of a cluster activation please refer to the Finca6 incidents.

Addendum 2704-A:
Incident Logs

Incident 2704-03
On █/██/19██ undercover field agent Marcelo Ocampo reported single sphere activation at 12:50 pm outside Costa Rican Center of Science and Culture. Geometric pattern which caused activation was not successfully recorded. ██ pedestrians were affected before Foundation interference. Local task force dispatched to evacuate office building and apprehend all affected parties.

Incident 2704-09
At 2:30 am on █/██/19██ an unknown number of SCP-2704 instances located in storage hangar 19B became activated. This incident occurred prior to the placement of a infrasonic detection system in storage hangar 19B, causing the exposure of 13 members of personnel. Surveillance cameras depict subjects undergoing mild to severe seizures. Personnel report hallucinations and migraines similar to those of public incidents, but at a much higher intensity. Current theories suggest this is due to subjects being exposed to several activated unorganized instances at once, but this is impossible to confirm.

Incident Finca6-1
At 1:30 am on █/██/20██ a group of five spheres began to emit an audible hum at a pitch of 13 Hz. Unlike the activation of unorganized SCP-2704 instances the effects of this activation, involving several instances in their original position, were immediate. All human beings within a 92-meter radius entered a state described similar to intoxication. Surveillance depicts many of the subjects seating themselves around the spheres in a semicircular formation. This activity continued for an approximated 7 hours. All members of personnel present, as well as Finca-6 security officers and pedestrians were interviewed after the incident. Recollection of information received by subjects during this incident was much greater than previous incidents. The following is an interview with agent Daniel Vega.

Contact has been made with Franklin Chan Diaz concerning incomplete blueprints provided by agent Vega. Dr. Diaz reported that the blueprints had several similarities to his own experimental designs concerning plasma propulsion, and suggested the blueprints were that of an advanced plasma propulsion rocket engine. Such a device would theoretically cause significant advances in interplanetary travel. However, knowledge in this field is currently insufficient to complete these designs.

Dr. Diaz has been given temporary Level 1 clearance on information concerning these blueprints, as well as a dedicated team of foundation research staff specializing in astronomy and engineering, in order to analyze and complete said blueprints. This team shall be designated Project Diquis. Any scientific discoveries brought on by the research of Project Diquis are to cleared by a member of Class B personnel prior to being released to the public.

Current theory presented by Dr. Quesada suggests that the purpose of these blueprints is to assist in the progress of human space exploration, specifically that of the dwarf planet Eris, which has yet to be visited by a spacecraft.

Incident Finca6-2
At 11:23 pm on ██/██/20██ 3 spheres began to emit an audible hum at a pitch of 19 Hz. The activation of these sphere has been determined to be caused by the formation of a triangle involving the dwarf planet Eris and two stars. All human beings within a 92 meter radius of the activated instance entered a state similar to that of Incident Finca6-1. Agent Gabriel Chavez, who was located 2 meters from the sphere during activation, was the only subject to undergo a complete hallucinatory episode. The following is an interview with agent Chavez after the incident
