SCP-5250

Item #: SCP-5250

Object Class: Keter

Special Containment Procedures: Any person or group of persons is capable of independently creating instances of SCP-5250, so physical containment in its typical sense is impossible. However, since creating an instance of SCP-5250 requires very specific knowledge, the monitoring and censoring of information regarding SCP-5250’s processes is a practical method of containment.

As far as the Foundation has been able to ascertain, knowledge surrounding SCP-5250 has been largely sequestered by a small group of interest calling themselves “Daemonologists.” Efforts to track down and infiltrate this group are underway.

Description: SCP-5250 is the designation given to any portal opened to SCP-5250-Λ.

SCP-5250-Λ, referred to simply as ‘Lambda’, is currently understood to be a four-dimensional universe, tangent to our own along the [redacted] coordinate of its W-axis. Lambda’s form of matter is incompatible with that of our own universe; however, both universes appear to share similar laws of acoustics, allowing interaction between the two given appropriate lab conditions.

History: While SCP-5250 has only recently been classified, the terms “Acoustic Daemonology”, “Harmonic Daemonology”, and “Acoustic █████████” have been on the Foundation’s watchlists for nearly a century.

Rumors of a ‘daemonology’ beyond the purview of the superstitious have long circulated, and in many cases, have proved to be related to something truly anomalous. In this case, it was a box of unique correspondences between three alchemists that initially alerted the Foundation.

They were alchemists of moderate repute who had all disavowed their profession, just a few decades before alchemy itself lost currency. These letters, written after their purported disavowals, indicated they had not abandoned their ‘aetherworldly’ pursuits, they had simply moved on to something with substance.

Although their correspondence explicitly avoided details on their methodology, their descriptions were nearly identical to those of Foundation researchers that dealt with interuniversal anomalies. Their language betrayed a knowledge keenly distinct from the mythos of the time.

That was the closest the Foundation would get to knowledge on SCP-5250 for another century. Sporadically, the Foundation would intercept various communications discussing acoustic daemonology, but these messages never provided enough information to get a lead.

Discovery: It was the death of one Dr. K████ R███, henceforth referred to as “the Professor”, that finally gave the Foundation actionable intel. The Professor had been under Foundation surveillance for a number of odd purchases relating to his experiments. A Foundation field agent implanted at the Professor’s university took his death as an opportunity to go through his personal belongings. Among them were an astounding number of tracts detailing the methods surrounding SCP-5250. His work allowed the Foundation to create an instance of SCP-5250 and confirm its existence.

In his manuscripts, the Professor had discussed the existence of a protégé. By cross-referencing the mentions of this protégé with the Professor’s class rosters, Foundation personnel were able to determine the identity of the protégé. Below is a transcript of the interrogation:

Addendum-A: A Brief Note on “The Daemonologists” Group of Interest

Via the Professor’s manuscripts, researchers were able to determine that the GoI operates with a basic cell structure in groups of no more than three. One member is considered the mentor while the other two are considered apprentices. Communication between cells exists in the form of an in-house mobile chat app which uses a novel form of encryption. Efforts to understand this encryption universally result in the self-destruction of the device being examined.

The primary goal of The Daemonologists appears to be the amassing of knowledge and “thralls” (henceforth SCP-5250-2) that can be used as weapons, ostensibly to defend the Earth against various end of the world scenarios.

Creating instances of SCP-5250-2 appears to be the Daemonologists’ primary use of SCP-5250. This process involves using SCP-5250 to extract instances of SCP-5250-1 from Lambda and containing them inside of a [redacted]-treated object, resulting in SCP-5250-2. Instances of SCP-5250-2 typically have some sort of anomalous property that relates both to the [redacted] symbols used and the object itself.

Despite the use of ████████, they do not appear to be a part of any other GoIs that are known to use it, though they are likely an offshoot or splinter group.
