Containment Protocols: Currently, all existing RPC-619 instances (4) are contained within a standard anomaly containment unit 20 by 20 by 10 meters in size, with a single dual-airlock entrance to the chamber. The cell lacks light sources and so possesses 2 NV-equipped security cameras for monitoring purposes. While the containment cell is removed from Site-007 proper, it remains under the jurisdiction of its administration and staff.1

Under no circumstances can light, iconography, or religious materials be allowed to enter the cell, and no rooms adjacent to the cell can have possible light/theogony sources brought inside. Photography of any kind, especially flash photography, is strictly prohibited.

Issuing Authority: GD-WEST
Reasoning: RPC-619 is too dangerous to test at this time. Until we possess a sufficient understanding of Groves Radiation and its effects, it is prohibited from testing.

Description: RPC-619 is a genus of monomorphic giant moths known as Coriolanus of the Erebidae family that was formerly endemic to Scotland (C. cominius, RPC-619-A), the Isle of Man (C. volumnia, RPC-619-B), and Northern France (C. caius, RPC-619-C), with a smaller subspecies (C. martius, RPC-619-D) within Quebec along the St. Lawrence River.

RPC-619's primary anomalous quality is its ability to "feed" off of Groves Radiation,2 in a process not dissimilar to photosynthesis, and "store" accumulated energy in their abdomen. Their abdomen is capable of producing 600-18,000 lumens with acquired Groves Radiation, depending on the amount absorbed beforehand. The rate of absorption in RPC-619 instances is currently unknown as well as the specifics of the radiation storage process, as RPC-619 was rendered extinct in the wild as of 1968, with the remaining instances unable to be tested due to standing containment protocols.

Notably, their abdomen is also capable of focusing this light in a concentrated cone that is used to deter/kill aggressors. This beam can cause intense Groves emissions of approx. 120-140 Vi,3 as detailed in the addenda below.

RPC-619 instances, especially in their larval state, were notorious for seeking out and feeding off of the ambient Groves Radiation of several religious artifacts and locations in their habitats, and on certain occasions, actively migrating in order to seek them out, with a notable preference for relics and churches of the Christian variety. It is believed that a sizable RPC-619 population (tentatively dubbed C. marcius) was once present along the Golden Horn of the Strait of Istanbul (formerly Constantinople), and most migrated from the area in the late 4th century for reasons unknown. It is believed that the C. marcius no longer exists, and records suggest that the species, which was reportedly far larger than any modern variant, went extinct in the 15th century after declining in numbers for several decades.

Addendum 1: Research Reports

Addendum 2: Discovery/Historical Excerpts

While documentation on the entities can be found as early as the 4th century, RPC-619 instances have been reported in more northern regions since the mid 15th century, with the first recorded description of a "Sunlight Butterfly" (A misnomer, due to the fact that RPC-619 is actually a moth) in the Scotichronicon, a legendary account/chronicle of Scotland's history by Walter Bower, a Scottish Abbot and historian. Once the manuscript was published in Latin in 1447, certain elements of the document were of interest to the then-fractured Auctoritas Ecclesiastica, such as reports on the tychokinetic properties of Alexander III of Scotland's coronation, descriptions of the confiscated relics of the Culdees' unique qualities, and specifically, descriptions of the Solis Papilio, or "Sunlight Butterfly". After Bower's death in 1449, the Auctoritas had the books confiscated and a modified edition was distributed to replace the original copies, which were now in the possession of the Auctoritas. An excerpt of one such description is recorded below, translated from Latin.

RPC-619-A had remained in Scotland for centuries during this time, with several other species eventually spreading across Europe, specifically Northern France and the Isle of Man. Documentation of RPC-619-C in France was less abundant, and the few records that did exist were lost during the National Convention's expulsion of Auctoritas personnel from French territory and the subsequent seizure of their assets, which were not recovered.

RPC-619-D populations in North America were fairly concentrated in more rural areas of Quebec that were possibly brought over by French colonists, but due to the incredibly different environment, these instances struggled to maintain a steady population and were eventually hunted to extinction in the early 20th century due to rumors of hostile RPC-619-D instances attacking farm animals in the region.

In the late 19th century, RPC-619's population in Europe was growing and beginning to pose a threat to secrecy, as even with their low population and often isolated nature of their habitats, they began to spread as they sought out larger and more populated places of worship. Mass extermination efforts by the recently formed Authority were enacted, with the successful neutralization of RPC-619-C instances in Northern France. Containment was seen as impossible given the size and scope of RPC-619 populations and the threat they posed due to fears over their usage of Groves Radiation, which was still a very poorly understood science.

Roggerio dei Frugardi's analysis of RPC-619, however outdated, did raise concerns over the "spores" (more akin to shed cells) spread by RPC-619, and fear that they may have carried Groves Radiation. Given that an effective method of measuring the presence of Groves would not exist for over a century, it was unknown exactly how much Groves Radiation could be spread by this process, and concerns over irradiation of the waterways led to this mass extermination, which allowed for the Authority to establish a stronger foothold in England which was previously less receptive to Authority involvement due to its Catholic background. Baeyer von Groves, son of Volker von Groves, published a paper shortly after his father's death that claimed that Groves Radiation was "…quite possibly one of, if not the most lethal sciences known to mankind, [and] my greatest fear is that it will go unrecognized until its devastating effects are realized." Baeyer's standing in the field, despite public perception of his father's insanity, incensed the ongoing extermination campaign. Baeyer would then be forced into the employment of the Reichsokkultabteilung (Imperial Occult Agency) in 1880 as the German military sought to weaponize Groves Radiation out of fear that the British occult community may be doing the same, although this was untrue at the time.

Certain aspects of Groves Radiation and the impact it may have on the territories of the United Kingdom were somewhat exaggerated by Authority personnel in order to be granted military access in Scotland and the Isle of Man, and while it was granted, it did cause several setbacks in the analysis of Groves due to paranoia of its effects.

This extermination was momentarily halted due to the beginning of World War 1. German zeppelin raids were difficult to repel at first due to the limitations of the British Empire's anti-air weapons and fighter planes, so MI13 sought to combat them through anomalous means.

Under the jurisdiction of Operation Lucre, the Authority began development of an anti-air weapon for the British that would utilize a radiation projector to damage and destroy aircraft. While some were opposed to giving such a weapon to a separate and potential future rival agency, particularly one linked to a national government, the considerable sum offered by the British in exchange, along with the prospect of field testing and the possibility of influencing the nascent MI13 organization, resulted in the project's approval.

Initial tests were unsuccessful. At the time, understanding of radiation was limited and no projector of the required strength that could be mass-produced was within the Authority's grasp. However, recent discoveries of electric stimulation causing RPC-619 instances to activate their cercus eventually led to the concept of utilizing RPC-619 as a "source" for these weapons. The original MI13 document is included below.

The Rossetti devices were disassembled following World War 1, with the RPC-619 entities (only 5 of which remained), components, and schematics now in the possession of the Authority. However, specialized machines (lacking any organic components but based on the original Rossetti design) remain in the possession of MI13 to assist in containment efforts beneath Westminster.

By the time MI13 and the Authority were better informed about Groves Radiation and RPC-619 in the 1920s, RPC-619 instances were critically endangered, with only a few RPC-619-A remaining in Harris of Scotland's Outer Hebrides, and completely isolated from their other habitats.

Once it was understood that RPC-619-A was almost extinct, a group of scientists (primarily Explorators of the Axton Hornsby Exploration Society) interested in their preservation for posterity and research purposes managed to acquire and contain several RPC-619-A instances. Early on in the study, an incident that resulted in an RPC-619 instance mortally wounding the head of the project resulted in the enforcement of a blanket test ban in 1928.

Given that test bans of this caliber can only be removed by authorization of a Global Director as well as rising escalations across Europe at the time, RPC-619 has remained in total isolation for decades and their population has decreased to five four as of 7/7/15 since entering containment. Given that RPC-619's biology suggests they are incapable of dying a natural death such as age, it is unknown how it died. Fears over lab safety and a lack of interest in or awareness of RPC-619 led to few inquiries into testing during this time.

It is believed that RPC-619 will be wholly extinct by 1/10/17.

Site Research Director Frederick McGantly,

RPC-619 is one of my assigned projects. It has been effectively mothballed within the Research Division due to the century-old test ban, not to mention the stigma surrounding it, and due to this zero-tolerance containment protocol, it appears that there is little time remaining until they go extinct.

Several hours ago, one of the five remaining RPC-619 instances died. There is no identifiable cause. It simply collapsed. As written in my previous email to you, the entities exhibited what I can best describe as extremely depressive behavior (moreso than usual), likely due to the fact that they've been kept inside for decades, and I believe that this death is a sign that they are now reaching the limits of their anomalous biology.

I tried to retrieve the corpse in the dark, but the remaining RPC-619 instances would not let me. I could feel them limply pushing me away. I do not understand why- and I decided to leave the corpse inside.

This behavior is entirely unexpected. There is no record of this activity before, and while I understand the test ban is still in effect, I am not intervening in what I believe to be a sort of funeral, with a similarity to those displayed by non-anomalous animals such as crows or dolphins, but especially elephants (see attached video).

Again, I am unsure, but this seems like more than a simple "funeral" as displayed by other animals- it's almost akin to a religious rite, with their strange procession around the body.
