Item #: XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX is to be kept at least 250 meters from any form of human transportation while not undergoing testing, as contact guarantees the eventual initiation of a Sigma-Epsilon event. Protective light-blocking covers should be secured with zip ties and industrial-grade adhesive over both ends of the object, to prevent inadvertent activation. No cutting tools or blades of any kind are to be allowed within the object containment chamber, barring during preparation for a test, in order to prevent removal of these covers.

Description: SCP-XXXX possesses the appearance of a World War I era naval periscope of the kind utilized on German U-Boats. Radioactive dating, however, has shown the item to be approximately 4.6 billion years old. This measurement is further supported by the aquatic nature of the object, although the reason behind its form, as well as how the form was attained, has proved elusive. SCP-XXXX appears completely normal until at least one of two possible triggering action takes place. The following is a brief outline of events that transpire upon the execution of a triggering action.

Scenario A: If the periscope is looked through correctly (as in through the bottom lens) and is not in contact with any kind of vehicle, the person who looked through it will begin to rapturously describe what they see through the object. Interestingly enough, the state of the top lens (covered or uncovered) has no effect on what is seen through the periscope, only on the outcome of the event. Subjects will invariably describe viewing the surface of an ocean. When asked to survey the area around them, subjects are unable to see any sort of vessel or craft, and are unable to see themselves when looking down. When asked about this discrepancy, subjects are incapable of perceiving that anything is amiss. This stage of the event can last indefinitely, assuming that the subject is provided with food and water. The final phase of the event begins upon the subject realizing that they are only viewing the surface of the water, and that, beneath the surface, there may be more to see. This conclusion is often reached independently by subjects, but can be suggested by researchers with no adverse effects in order to speed up testing. Upon angling the periscope downwards, subjects fall silent and cease motion for several seconds, before either being sucked into the lower lens of the object or, if the upper lens is covered, converting into what chemical analysis has shown to be a mixture of seawater and many other body fluids commonly found in the human body. It has been hypothesized that the subjects who are transported through the periscope undergo the same transformation but are transported prior to being affected by gravity.

Scenario B: This scenario will only occur when SCP-XXXX comes into contact with a vehicle but is not looked through. The scenario progresses as follows:

1: Personnel on the vehicle will begin to report uneasiness, as though they “Should not be there”.

2: The sound of waves will become audible. This sound is able to be recorded, but no discernible source has been located as of yet.

3: The vehicle will begin to rock as though buffeted by wind or waves. This will occur no matter the location of the vehicle, and, though proving to be distracting, will not impede mechanical function of the vehicle.

4: The vehicle will start to be assaulted by sharpened spikes of what appears to be carved whalebone. The bones will invariably cause punctures in the outer layers of the vehicle, through which large quantities of seawater will begin pouring. This water has no discernable source, and traces of this water will usually remain after the conclusion of the event.

5: Personnel will begin to hear something that is described as “similar to whale song, but angry”. This sound is not able to be recorded and appears to be wholly psychic in nature.

6: [DATA EXPUNGED]

7: The resulting mixture will begin be siphoned into the periscope, leaving only vehicle fragments and small traces of bone marrow behind.

Scenario C: This scenario will only occur when the object is looked through while attached to a vehicle. The only requirement that needs to be satisfied in order to classify an object as a vehicle seems to be that it is used to carry people. The scenario will progress as follows:

1: While the vehicle is in motion, the periscope comes into contact with the vehicle.

2: While in contact with the vehicle, the periscope is looked through.

3: Through [DATA EXPUNGED] large masses of [DATA EXPUNGED] finally resulting in the complete dismemberment of the vehicle. In the seconds before death, personnel have expressed the experience of having a vision of an enormous mass of carved, polished bone, roughly spherical in shape, rising from a churning ocean. Participants in this event frequently express amazement and joy at the sight of it. This effect extends to those who are naturally blind, as well as those whose eyes have been surgically removed, indicating that it is being experienced only in the minds of subject.

4: [DATA EXPUNGED] are then separated from any connective tissue and [DATA EXPUNGED]. This is hypothesized to be the reason behind the gradual increase in [DATA EXPUNGED]

5: By this time, no traces of the vehicle or any involved personnel remain. No cleanup is necessary.
