31 minutes later, the site transmitted once, via electronic message, 
under the command code of Site Director James Julien. “He is 
come, crowned with fire. The Hall is made perfect through his 
presence. It is not enough. His anger is writ upon our flesh. He will 
leave. He has returned. Long live the Last King. All is found. We've 
stopped him. It will not last.” Attached to the message was a blurry 
image of a humanoid figure, silhouetted by a bright light. 


Remote investigation of Site- revealed the site to be empty of all 
life, human, SCP, and test animals. The base had been stripped 
bare, leaving only the walls intact. There was no sign of bloodshed. 
The containment cell that had originally held SCP-2976-Beta 
appeared to have suffered heat damage, the walls blackened with 
non-anomalous soot. Site- was decommissioned and filled with 
cement.

SCP-356-A: [sighs] These are quite silly, you 
know. Do you remember being born? Maybe 
you should try asking _, he might have some 
pictures somewhere. He'll probably tell you 
where they're stashed if you ask him when 
he's in a box. He has a strained relationship 
with tight, confined spaces. 


Researcher Singh: So you have no 
information on this subject? 


SCP-356-A: | can certainly tell you and!

But then you already know that. You came 
knocking on their door.

Researcher Singh: Can you make contact 
independent of SCP-356? 


SCP-356-A: You'd like to know that, wouldn't 
you? Ask. Oh wait, you did already. I'd help 
more, but you know, | help so much already. 
You'll have to do at least a little work here.

SCP-2977: Periscope Ants 


Item #: SCP-2977 
Object Class: Euclid 


Special Containment Procedures: Due to the unpredictability of 
the emergence of SCP-2977-2, SCP-2977 has been publicly 
designated as a critically endangered species and provided 
protection under the multilateral CITES treaty. Non-anomalous 
research data may be considered for public release at the discretion 
of the Lead Researcher. 


Mobile Task Force Upsilon-7 ("The Glass Jar’) are to monitor 
international conservation groups for descriptions matching 
SCP-2977-1. MTF Y-7 are to investigate possible instances, locate 
SCP-2977-2 using chemical pheromone tracking and ground- 
penetrating radar, and convert affected areas into Provisional Sites 
under the guise of preservation efforts.1! SCP-2977-2 must be 
located before full containment is enacted. 


Due to the extreme rarity of both SCP-2977-1 and SCP-2977-2, 
future excavation attempts must be approved by both the O5 
Council and the current coordinator of Project Longfellow. 


Description: SCP-2977 are a species of eusocial insect of the 
family Formicidae, commonly known as ants. SCP-2977 members 
are black in color and reach between 13 mm and 20 mm in length 
depending on caste. SCP-2977 are externally distinguishable from 
other Formicidae by their limited reproduction cycle and the 
characteristic "rainbow" or "bullseye" pattern of debris surrounding 
their colonies. SCP-2977 also cultivate unusual food species in 
underground reservoirs in a pattern of agriculture-like mutualism, 
including Amblyopsidae (Blind cave fish) and tardigrades. 


SCP-2977 colonies, designated SCP-2977-1, expand almost directly 
downward to extreme depths, rarely exceeding 1.5 m in diameter 


below the surface. SCP-2977-1 are known to extend below 15 km, 
the maximum depth currently attainable by Foundation technology. 
The concentric circle pattern of debris surrounding each 
SCP-2977-1 is created when SCP-2977 members bring excavated 
material from the deepest point in their colony to the surface, with 
deeper minerals forming new rings as older debris are pushed 
outward. 


SCP-2977-1 are considered "mature" when they reach an estimated 
final depth of km and cease producing new debris. (A summary of 
minerals surrounding a "mature" instance is available in Addendum 
2977-1.) Mature colonies produce nuptial flights of male and fertile 
queen SCP-2977 members in order to produce new SCP-2977-1. 
This occurrence is extremely infrequent, and has only been 
observed 16 times across all Sites since initial containment in 1914. 


SCP-2977 instances have not displayed digging capabilities superior 
to those of non-anomalous Formicidae. Based on observations of 
expanding debris patterns around multiple SCP-2977-1 over time, it 
is estimated that the time required for a new SCP-2977-1 instance to 
reach a “mature” depthis years. 


SCP-2977-1 are always found in close proximity to a “source” 
colony, designated SCP-2977-2. SCP-2977-2 emerge sporadically 
in areas of high volcanic and tectonic activity, primarily in the Pacific 
“Ring of Fire”. It is believed that SCP-2977-2 originate at an 
unknown depth and expand upwards until they break the surface, 
leaving only entry tunnels visible. 


Unlike typical SCP-2977 queens, queens emerging from 
SCP-2977-2 are wingless and reproduce by asexual 
parthenogenesis. SCP-2977-2 queens also display significant 
genetic aberrations from SCP-2977-1-produced queens. (Genetic 
analysis results are available in Document 2977-2.)

Document SCP-2977-2: Genetic Variation in 
SCP-2977 Queens 


From: Dr. Alexandre Honoré, Lead 
Researcher, SCP-2977 


CC: Dr. Jennifer Torres, MTF Leader, Y-7 
To: O05 Command, Overwatch HQ 


The limited reproduction rates of SCP-2977-1 
and SCP-2977-2 have resulted in significant 
difficulty capturing queens for analysis. Still, a 
concentrated -year program has provided us 
with samples from all known sites, allowing us 
to successfully categorize genetic and 
physiological aberrations between various 
SCP-2977 queens. 


First, queens produced by SCP-2977-2 
contain anomalously uniform noncoding DNA, 
with all DNA not absolutely essential to protein 
coding or biological function following a 
repeating GACTGACT pattern. Second, the 
RNA-mediated transcription and translation 
process in SCP-2977-2 queens is extremely 
efficient, but also extremely prone to mutation. 
Third, mutations expressed in noncoding DNA 
in any cell are uniformly replicated in all new 
DNA across the organism. 


Queens originating from "mature" SCP-2977-1 
display more typical genetic diversity and DNA 
reproduction than SCP-2977-2 queens, 
although the nonessential noncoding DNA in 
SCP-2977-1 queens is vastly different 
between containment sites. Analysis of genetic 
differences between these queens suggests 
that specific genetic sequences are directly 
related to minute details of geography, climate, 
and even level of human interaction or 
observation. 


The genetic plasticity of SCP-2977-2 queens 
and the level of detail reflected in queens from 
SCP-2977-1 suggest that SCP-2977 may 
serve as a novel, if inefficient, information 
storage and transportation system. 


Document SCP-2977-Longfellow 


From: O05 Command, Overwatch HQ 
To: All Level 3/Longfellow personnel 
CC: MTF Y-7 personnel 


For the purpose of developing a long-term 
containment policy, it is to be assumed that 
SCP-2977 is an engineered species used for 
surface reconnaissance by unknown deep- 
subterranean beings, likely SCP-2977-3. It has 
been determined by a 7-5 vote of the O5 
Council that communication with any such 
inquisitive species is essential in order to 
prevent any more intrusive - and potentially 
geologically catastrophic - attempts to explore 
the surface. 


Given the approximate 300 years it takes 
SCP-2977 to "return" from the surface, 
attempts to use genetically modified SCP-2977 
as an extreme-long-delay communication 
system to establish contact with SCP-2977-3 
have been approved within the mandate of 
Project Longfellow. Newly assigned SCP-2977 
personnel should consult Document LF-1886: 
Introduction to Pan-Generational Research 
and Document LF-1947: Maintaining 
Continuity in the GigaYear Range for more 
information.

SCP-2978: Motherburg 


Item #: SCP-2978 
Object Class: Safe 


Special Containment Procedures: All instances of SCP-2978 are 
currently contained in Site-17, secured in a biometrically locked 
chamber. The containment chamber, and all SCP-2978 communities 
within, are to be observed at all times using high-speed HD camera 
surveillance and digital microscope systems. Access is limited to 
Level 2 staff. 


No storage peripherals exceeding 128MB in size are to be inserted 
into any SCP-2978-A instance. Should populations of SCP-2978-B 
increase to over SCP-2978-A capacity, additional sections of 
compatible hardware are to be added to prevent overpopulation 
events. 


Addendum-2978-02: Following Test-2978-23, a second biometrically 
secured entrance has been added outside the primary containment 
cell. Additionally, no wireless networking peripherals are permitted 
for use with SCP-2978. 


Description: SCP-2978 consists of two anomalies, SCP-2978-A 
and SCP-2978-B. 


SCP-2978-A is a collection of anomalously modified Intel 
D945GCPE microATX motherboards normally found in Intel Pentium 
4 Personal computers. Anomalous properties are only apparent 
when examined in close proximity. All components of the 
motherboards are modified to function as a miniaturized urban city 
environment. 


All USB ports of SCP-2978-A were occupied by [REDACTED] 
brand 256MB USB drives when recovered. These thumb drives 
have resisted all attempts at removal thus far (Number of thumb 


drives reduced to , see Event-2978-Beta). 


SCP-2978-B are a race of silicon-based, humanoid individuals 
measuring 400-500um in height and weighing 50-80ug variably. All 
SCP-2978-B have a green skin tone with no visible hair; however, 
each individual has a unique physical appearance, behavior and 
personal life within the SCP-2978 community. SCP-2978-B emulate 
a human society, with technology analogous to the 1990's. 
Individuals use a modified version of English for communication and 
do not need sustenance. 


SCP-2978-B have a lifespan of approximately 90 hours (this 
includes: birth, schooling, careers, reproduction, family life and 
death). High-speed camera equipment is required to observe 
individuals’ daily lives. 


SCP-2978-B seem incapable of perceiving humans, the exception 
being an individual named "Our Father" (hereafter referred to as 
POI-2978). SCP-2978-B can, however, be physically interacted with, 
causing various detrimental effects to their perceived normalcy. 
References to POI-2978 appear in media and religious depictions in 
SCP-2978 communities. 


Once compatible hardware makes physical contact with an 
SCP-2978-A instance, it will be converted into an SCP-2978-A, by 
SCP-2978-B individuals, within 11 to 15 hours depending on 
complexity. Hardware manufactured after 20 does not seem to be 
affected by SCP-2978-A's modifications. Current theories are that 
SCP-2978 instances have a set software version, only updated by 
the creator of SCP-2978. This would have stopped after 20 , the 
year of containment. 


All communities are named "Motherburg", with the suffix "V1.x" 
added to each new iteration. On all SCP-2978-A instances, the 
following will be printed on an upright transistor, located near the 
edge of the motherboard: "Welcome to Motherburg, Population: 
(variable)". As of 04/10/20 , "Motherburg V1. " is the last 
community to have been built. 


No power source is utilized for the functioning of SCP-2978. 


Report on Event 2978-Beta 


On 24/12/20 Junior Researcher Milborrow, was seen 
commencing daily observations. Of note, he had not 
informed staff that he had been experiencing a head lice 
infestation. After concluding observation, surveillance 
footage shows him scratching his scalp as he leaves 
containment. Digital microscope footage shows 
numerous SCP-2978-B individuals fleeing an area of 
SCP-2978-A-24. 


Intercepted media from SCP-2978 shows local news 
reporting the appearance of "monsters", encouraging 
community members to flee to SCP-2978-25. After 
moving the position of SCP-2978-24's digital microscope, 
3 Pediculus humanus capitis (Head louse) are seen 
crossing the object's surface. 5 minutes after contact, all 
SCP-2978-B individuals have evacuated SCP-2978-24. 
Due to the unexpected nature of the event, numerous 
SCP-2978-A-25 structures served the secondary 
purpose of a makeshift dwelling. Researcher Eddleston 
expressed interest in the preceding events and obtained 
Site Director permission to continue observation. 


In the following hour, the first increases in birthrates were 
observed, possibly caused by overcrowding. Neighboring 
SCP-2978 communities expressed disinterest in allowing 
the immigration of SCP-2978-B individuals. 2 hours after 
Event-2978-Beta began, living space had become a 
serious problem and births had increased further. 
Neighboring SCP-2978-A communities enacted border 
patrols which prevented immigration, causing hostility. 


At the 4 hour mark, the lice, still present on 
SCP-2978-24, were seen behaving as typical to their 
species, with a single louse moving towards 
SCP-2978-25. No attempts of their removal had been 
made. Living space and resources had now become 
critical problems on SCP-2978-25, with rioting and 
violence becoming a common occurrence.
