Copies of SCP-7655-A are to remain in continuous print and circulation without significant alterations. Academic institutions specializing in East Asian historiography are to be monitored for the potential discovery of copies of SCP-7655-B, and are to be contained accordingly. The containment of SCP-7655-C has been entrusted to the Holy See until further notice.
SCP-7655 is a collective designation for at least 5 documents dating to the 17th century. The documents primarily possess an obscurative effect on the perception of historical records between the years 1600 and 1687. This effect appears to be deeply rooted in the noosphere, such that it affects individuals who have no knowledge of SCP-7655 or their mundane versions.
SCP-7655-A denote the Instrumentum Pacis Osnabrugensis, both January and October iterations of the Instrumentum Pacis Monasteriensis, and all reproduced documents that contain the entirety of their text.1 While anomalous, it is not possible to discern the nature of their effects without prior knowledge of noospherics and esoteric informatics. Due to the consideration of other factors, their continuous existence outside the Veil is deemed satisfactory and essential.
SCP-7655-B refers to an internal document issued by the Ministry of Rites.2 Divided into multiple subsections, it details the formalization of the transfer of the Ministry's loyalty and service from the Ming to the emergent Qing. While it is believed that the document was distributed among members of the Ministry, its practices suggest the destruction of all extant instances to preserve secrecy. The document currently within Foundation custody was obtained directly from the Ministry's archives following its various mergers and restructuring into the Foundation.
SCP-7655-C is an unfinished manuscript of Isaac Newton's Philosophiæ Naturalis Principia Mathematica, intended to have been published as its fourth volume. The manuscript primarily discusses Newton's alchemical experiments, in addition to his theological beliefs and contemporary analysis of Christianity. It is not fully understood how the Holy See came to possess this copy, but its latter contents have been cited as justification for its seizure.
When any instance of SCP-7655 is read while under the influence of Class-E mnestics, individuals will become aware of significant discrepancies in the historical record, mostly within the 17th century. This may lead to the immediate onset of nausea, vomiting, headaches, seizures, and in one instance, the spontaneous development and progression of Stage 2 SCP-6993.3
The nature of the vast majority of discrepancies suggest the existence of a large scale, possibly worldwide anomalous conflict taking place during this time period. Based on current studies and widely accepted parahistoriography, this would be classified as the Fifth Occult War.4
Continued exposure to SCP-7655 under mnestic influence may result in deleterious effects on the individual's memory, personality, cognitive ability, and continuation of self.
Addendum 7655.01
Due to the subjective nature of SCP-7655's effects, several tests were conducted over an intellectually diverse sample size to gain further insight on the aforementioned discrepancies, and whether they are indicative of a reality restructuring event or merely constitute hallucinations.
Attached are a selection of such tests.
Addendum 7655.02
It is believed that among the other instances of SCP-7655 that exist, they most likely serve to obscure the effects of the so-called Fifth Occult War across the rest of the world, with emphasis on the Ottoman, Safavid, and Mughal empires, and to a lesser extent any anomalous phenomena in the Americas.
The identification and acquisition of any and all undiscovered SCP-7655 instances is considered top priority. The acquisition of SCP-7655-C is currently underway, pending a formal agreement from the Papacy involving its exchange for minor Catholic artifacts in Anomalous Items storage.
