Experiment 3769-F was an attempt to discover the 
genetic nature and origin of SCP-411. However, upon 
attachment, SCP-3769 emitted rapid bursts of light from 
its display screen and ejected itself from the subject. The 
subject did not undergo any genetic or physiological 
alterations during this process. SCP-3769 became 
completely unresponsive for three days following this 
event before spontaneously reactivating. Following this 
revival, SCP-3769 was found to no longer evolutionarily 
regress organisms during Rescission Evenis. Instead, 
organisms exposed to SCP-3769 adopt genetic and 
physiological forms not present in the fossil record. It is 
theorized that SCP-411’s reversed temporal properties 
may have caused SCP-3769 to rewire itself and reverse 
in function, transforming affected organisms into an 
evolutionary descendant rather than an ancestor. All 
experimentation involving SCP-3769 after the events of 
Experiment 3769-F have been categorized as Post-F 
experiments, and have been marked with the 8 symbol. 


Addendum 3769.4: Post-F Experiment Logs 


Experiment 3769-6A 

Subject: Theropod Dinosaur of unknown 
species (from Experiment 3769-C) 

Number Entered: 80 

Rescission time: 7 hours and 57 minutes 
Results: Subject experiences degeneration of 
the hands, teeth, and tail, along with a 
decrease in size and the rapid generation of 
feathers. Subject resembled a domestic 
chicken by the end of the process. 


Experiment 3769-6B 

Subject: Brown rat (Rattus norvegicus) 
Number Entered: 50 

Rescission time: 4 hours and 41 minutes 
Results: Subject expanded to nearly five 
times its original size. The legs of the subject 
greatly increased in length, and the toes 
converged into singular hoof like structures. 
The fur of the subject adopted a pattern of 
brown vertical stripes. Following the 
Rescission Event, the subject was recorded 
running at speeds of over 32 


Experiment 3769-6C 

Subject: Rhesus macaque (Macaca mulatta) 
Number Entered: 50 

Rescission time: 4 hours and 19 minutes 
Results: Subject experienced a 
disproportionate expansion of the hind limbs, 
claws, and maxillary canines, as well as a 
decrease in the length of the tail. All fur on the 
subject increased in length and darkened in 
hue. Following the Rescission Event, the 
subject was observed moving in a manner 
similar to marsupials of the family 
Macropodidae (kangaroos). 


Experiment 3769-6D 
Subject: Common Octopus (Octopus vulgaris) 


Number Entered: 200 

Rescission time: 11 hours and 16 minutes 
Results: Subject developed a cartilaginous 
skeletal structure resembling a spine within 
each tentacle, as well as an enlarged cranial 
cavity. The two frontmost tentacles extended 
in length and each diverged into four flexible 
secondary appendages. Subject drowned 
within it’s aquatic containment tank before the 
Rescission Event was completed. The 
subsequent autopsy revealed that the 
subject’s gills had transformed into primitive 
lungs. 


Experiment 3769-6E 

Subject: D-8897 (Homo sapien) 

Number Entered: 10 

Rescission time: 1 minute 

Results: Subject died before undergoing any 
physical alterations. SCP-3769 ejected itself 
prematurely upon the death of the subject. 
Cause of death is unknown. 


Experiment 3769-6F 

Subject: D-4272 (Homo sapien) 

Number Entered: 1 

Rescission time: 1 minute 

Results: Subject died before undergoing any 
physical alterations. SCP-3769 ejected itself 
prematurely upon the death of the subject. 
Cause of death is unknown. 


Experiment 3769-6G 

Subject: D-6502 (Homo sapien) 

Number Entered: 0.1 

Rescission time: 1 minute 

Results: Subject died before undergoing any 
physical alterations. SCP-3769 ejected itself 
prematurely upon the death of the subject. 
Cause of death is unknown. 


Experiment 3769-6H 

Subject: D-7033 (Homo sapien) 

Number Entered: 0.00005 

Rescission time: 1 minute 

Results: Subject died before undergoing any 
physical alterations. SCP-3769 ejected itself 
prematurely upon the death of the subject. 
Cause of death is unknown. 


Addendum 3769.5: Appeal to The O5 Council 


The following is an email delivered by Site director Dr. 

to the [DATA EXPUNGED] of the O05 council 
regarding the possibility of an XK-Class End of the World 
Event. The approval of at least two (2) Level 4 personnel 
is required in order to access this file. 


From: Dr. 
Subject - Possible XK-Class Event 


Greetings, Council, 


Let me begin by saying that | understand the 
exclusive nature of this method of 
communication, and that | would not under any 
circumstances contact you all if | did not have 
information of the utmost priority. That being 
said, | believe that some of the data resulting 
from the Post-F experiments of SCP-3769 may 
indicate an imminent catastrophe of 
apocalyptic proportions. 


Following an attempted experiment on 
SCP-411, SCP-3769 has essentially reversed 
in function, altering affected subjects along 
their line of evolutionary descent rather than 
ancestry. This has been all but proven by the 
use of SCP-3769 to transform a dinosaur from 
a previous SCP-3769 experiment back into a 


domestic chicken. From this, it can be 
assumed that all other subjects altered by 
Post-F experiments have taken on the forms of 
organisms that have yet to evolve but will 
eventually. 


However, all Post-F experiments performed on 
human subjects have resulted in death within a 
minute of SCP-3769 contact, with no 
noticeable alterations taking place. This 
occurred even when the value 0.0005, shown 
to be equivalent to approximately one 
generation in previous experiments, was 
entered into SCP-3769. The exact reason for 
this has not been definitively proven, but given 
the nature of SCP-3769, | am forced to believe 
that it may indicate the future extinction of 
mankind, possibly within our lifetime. 


| do not know what, if anything, can be done to 
prevent this outcome. | would recommend that 
more advanced containment measures be put 
in place for all Keter SCPs. However, it is not 
my place to make these decisions. | hope that 
by alerting you all to this situation appropriate 
measures can be taken in order to ensure the 
continuation of our species. 


Regards, 
Dr.

SCP-3770: One Thousand Footsteps Towards The 
Promised Land 


Item #: SCP-3770 
Object Class: Safe 


Special Containment Procedures: All SCP-3770 instances are to 
be kept in separate groups of 2-20. Each group is to kept in a secure 
vivarium at least 20cm long, 10cm wide, and with substrate 10cm 
deep. The substrate is to compose of coconut fibre, decaying 
deciduous leaf litter, a calcium source such as powdered cuttlefish 
bone, and small amounts of sand. A small layer of dry leaf litter is to 
be provided above the substrate. Under no circumstances is pine to 
be used in SCP-3770 containment chambers. 


The vivarium is to be kept at a temperature of 22-24 degrees celsius 
and have a humidity of 60-80%. No sudden changes in climate are 
to take place. Each vivarium is to be kept in a room with a light 
source activated by solar power, as to replicate natural lighting. If an 
SCP-3770 instance shows any sign of molting, caution is to be held 
due to the vulnerability of instances during the process, and the 
substrate is not to be replaced unless in emergency. No pesticides 
are to be present in SCP-3770 containment chambers. All materials 
introduced to SCP-3770 instances are to be organic. Fresh fruit and 
vegetables are to be given to each group on a weekly basis, being 
left for two days prior to removal. 


Description: SCP-3770 is the designation given to an anomalous 
subspecies of Centrobolus Splendidus!. SCP-3770 instances are 
capable of communication through auditory means at high frequency 
with all species of arthropod capable of processing signals sent. 
Audio does not affect any known vertebrate or invertebrate which is 
not a terrestrial arthropod. All invertebrates which receive 
communications from SCP-3770 instances display abnormal 
behaviour, showing higher intelligence and extreme co-operative 


ability (see testing logs for more details). 


SCP-3770 will occasionally display a behaviour known as a 

"3770 1A event", in which instances will begin to chew wood pulp 
into a paper-like material. Instances then consume any brightly 
coloured, white, and black substance possible. The materials will be 
secreted through the anus as dye to the paper. The paper will then 
be fashioned into a square shape by use of instances’ mandibles. 
Images formed through use of the dyes generally resemble images 
of invertebrates, deciduous forests, in a style associated with 
Byzantine religious artwork. Images contain text of unknown origin. 


Similar to the defence mechanism of most Diplopoda, SCP-3770 will 
secrete an irritating liquid. SCP-3770, however, constantly secrete 
said liquid. Although this has the chemical makeup of ordinary 
Centrobolus Splendidus secretion, if it comes into physical contact 
with any form of sapient life, severe visual hallucinations occur. 


+ Testing Logs A-E 


Several experiments have been conducted exploring the 
anomalous effects of SCP-3770. These are recorded 
below. 


Test A - 27/07/2017 

Procedure: To place an instance of SCP-3770 
within a vivarium containing an individual 
Scolopendra Subspinipes Dehaan® 
(SSD-0001-D) for 1 week. 

Results: The SCP-3770 instance was not 
harmed. SSD-0001-D began to construct a 
model resembling a coccinellid using moist 
substrate. 

Analysis: SCP-3770's effects are capable of 
supressing predatory instincts. 


Test B- 29/07/2017 

Procedure: To insert an auditory arthropod (a 
Gromphadorhina portentosa* designated 
GP-0001-D) within an SCP-3770 containment 
unit containing 15 individual SCP-3770 


instances. 

Results: GP-0001-D showed abnormal 
behaviour, occasionally placing each end of its 
upper 2 legs together, whilst using the lower 
pairs to balance upright. Whilst doing so, 
GP-0001-D began to create loud respiratory 
"hisses" (as is common in the species) at short 
intervals translated to Latin morse code. Lines 
commonly repeated by GP-0001-D include: 


¢ "Forgive my soul, oh lord, forgive me 
and forgive all of your other children." 


¢ "By the grace of all the legs that you, oh 
dear and righteous god, have used to 
create our precious bodies, | thank you 
with all my open circulatory system." 


"| hope that one day | will join my 
brothers with you, oh father, my lord, at 
the completion of the promised land. 
Show me the way to devote my humble 
life as did your 87 saints, oh lord." 


Analysis: SCP-3770's effects can radically 
heighten intelligence. 


Test C - 30/07/2017 

Procedure: To introduce an SCP-3770 
instance to an individual Argiope bruennich® 
(AB-0001-D) . 

Results: AL-0001-D began constructing a line 
of Latin text by producing abnormally 
patterned web. This translated to: "We fly with 
our father, we ride through the moon, the sky, 
the stars. Now by miracle we may see him 
again. Our father, the promised land." 
Analysis: SCP-3770's effects can be utilised 
for a large range of species. Further research 
on the meaning of material produced is to be 
conducted. 


SCP-489: 1-555-BUG-BASH 


Item #: SCP-489 
Object Class: Euclid 


Special Containment Procedures: SCP-489 is held in a 
containment unit at Site-113. To prevent personnel accidentally 
bringing insect life into SCP-489's cell, a shower room has been 
established outside of the containment cell; personnel will change 
into the clothes provided to them after cleaning. Testing with 
SCP-489 is limited to indoor spaces. 


Due to the potential of containment breach and site damage, at no 
point may insectile based anomalies, including instances of 
SCP-831, be stored at Site-113. 


Description: SCP-489 is a roughly dome-shaped conglomerate 
mass consisting entirely of objects used to kill or repel insects (e.g. 
aerosol pesticide cans, "bug zappers", flyswatters, footwear, and 
lighters). Each item is capable of independent autonomous 
movement, though they usually move along the ground as a whole 
when in motion. As of June 17, 2013, SCP-489 measures roughly 
five meters in height, and eight meters in diameter at the base. 


There is a badly damaged transit van in the center of the mass, 
which contains a human skeleton sitting in the driver seat; the 
skeleton's rib cage has been crushed. A faded, scratched logo can 
be seen on the right side of the van, which reads: 


Xtreme Xtermination [sic] Services. 
We'll bash any bug, big or small! 
1-555-BUG-BASH 


When an insect of any species comes within five meters of 
SCP-489, SCP-489 will surge towards the animal and attempt to kill 
it; of note is that SCP-489 is heedless of other non-insect organisms 


Test D - 30/07/2017 

Procedure: To introduce an SCP-3770 
instance to a colony of Camponotus 
Pennsylvanicus® (CPC-0435), whilst providing 
the colony with a sheet of ply wood. 

Results: CPC-0435 engraved an image of 
what appeared to be multiple stellar 
formations, and planets such as "Venus", 
"Mars", "Jupiter", and "Saturn". A large 
coccinellid was in the place of Earth, bearing 
what appeared to be a "halo" above its head. 
This was created in similar fashion to images 
produced during 3770 1A events. 

Analysis: Further research on the meaning of 
imagery and text produced by SCP-3770 is to 
be conducted. 


Test E - 31/07/2017 

Subject: Dr. Telford 

Procedure: In order to study the 
hallucinogenic effects of SCP-3770, the 
subject will induce SCP-3770's effects and 
record what is visually experienced. 
Results: See Document-3770-E for a log of 
recorded information provided by Dr. Telford. 
Analysis: See Document-3770-E for details. 
Further research involving SCP-2794 is to be 
conducted in conjunction with MTF Mu-77. 


+ Document-3770-E 


During test E, Dr. Telford, a member of MTF 
Mu-77's research personnel, documented his 
experience on audio after contacting 
SCP-3770's secretion. 


Dr. Telford: Visual hallucination has begun, 
recording has started, commencing test. Initial 
image is of what appears to be a swampland 
environment, very fertile and abundant in life. | 
see a large amount of flying insects, various 


arthropods on the ground, and no birds in the 
sky, which is a dark shade of green. The area 
overall is dark and verdant. 


[Dr. Telford begins to walk around the 
testing area] 


Dr. Telford: There's a warmth pulsating from 
the ground, and a faint throbbing? Heartbeats, 
but not mine. | see something in the sky- | 
thought it was a faint cloud at first but now 
some mist has cleared, | am relatively close to 
the planet Jupiter. 


[Dr. Telford crouches down] 


Dr. Telford: The floor is moist and warm. 
Everywhere is so humid and abundant with 
life, but yet no birds, mammals, reptiles, fish, 
amphibians, nothing. Just bugs it seems. They 
all seem so healthy, the fertile landscape must 
be providing food. | can see predatory animals, 
giant centipedes and scorpions, all eating this 
green fungus-like material along with isopods, 
caterpillars, and others. Curious. 


[long pause] 


Dr. Telford: Burrows and nests are 
everywhere. This fungus is all around me in 
the ground. It seems to be sprouting from this 
green organic waste-like material. Curious, it's 
as solid as rock, must be the base of whatever 
I'm on. It's so tough, yet plant life is growing 
from it. 


[Dr. Telford looks up with a surprised 
expression] 


Dr. Telford: | can see it now, | thought it was 
just part of the atmosphere but it's a body. I'm 


on a leg, miles wide, hundreds of miles long. 
That's a body, a ladybird? And what I'm 
standing on, this hard green rock? That's what 
this thing is made of. It reminds me of 
something. 


[Dr. Telford breathes heavily]
