After a successful mutation is completed, subjects normally display 
an intelligence level typical for what is considered average for their 
species. Several subjects have shown a somewhat increased 
capacity for problem solving than is considered normal for their 
species; whether this is due to neural restructuring or a byproduct of 
Foundation testing is currently unknown. Many subjects which 
develop proper vocal cords are able to learn to speak, but typically 
only with rudimentary phrases of basic needs (such as food, sleep, 
play, etc.) Similarly, most subjects are able to achieve full mobility 
within two-to-four weeks of stabilization, though manual dexterity 
takes far longer to perfect if the original species had simple paws or 
hooves. 


SCP-1575-1 does not have any notable effect on a creature's 
personality, memories or instincts; all carry over from the individual 
animal's existing self despite drastic restructuring of the brain. 
Domesticated animals typically retain previous levels of affection for 
humans, though the physical and mental trauma of the mutation 
process often leads to cases of depression and other psychological 
issues. 


Humans have not been observed to experience any notable effects 
when ingesting SCP-1575-1. Non-mammalian creatures will mutate, 


but due to significant physiological differences they will have a 
99.9% fatality rate due to drastic and incongruous physiological 
differences. Only 2 non-mammalian mutations were known to have 
stabilized; neither had completely changed to a human form, and 
both were euthanized after brief study. 


Addendum 1575-1: SCP-1575 was recovered from a facility named 
"The Miracle Farm", previously owned and operated by Marshall, 
Carter & Dark Ltd. The stated goal of the facility was to "present our 
clients with the finest in custom-ordered pets, prey and 
companions." Mobile Task Force Theta-2 ("Moreau's Morgue") was 
able to secure the facility, on-hand personnel, attending clients, 
and living specimens in various stages of mutation; only 
specimens were deemed fit for transportation and study, all others 
euthanized on-site. Farm personnel and clients were detained for 
questioning, then given class A amnestics and released. A cover 
story of a runaway fire was implanted in their memories before 
release to explain the destruction of their facility. 


According to obtained records, at least specimens were known to 
be in possession of clients of MC&D. MTF Theta-2's current mission 
is to track down and recover or destroy said specimens; thus far, 
have been accounted for. 


Addendum 1575-2: Select testing logs 
Access 1575 testing logs (Level 2 security clearance required) 


Test 1575-2 

Subject: Female Japanese field mouse 
(Apodemus argenteus), adolescent 

Result: Subject expired after twelve (12) days. 
Cause of death determined to be due to 
overall body size increasing faster than the 
cardiovascular system was able to supply. 
Notes: Subject had undergone a 500% 
increase in overall size, measuring 
approximately 1.01 meters. Subject had been 
observed consuming nearly 95% total body 


weight per day before expiration. 


Test 1575-4 

Subject: Male white-tailed deer (Odocoileus 
virginianus), preadolescent 

Result: Partial transformation, stabilized after 
thirty (30) days. 

Notes: During mutation, subject suffered 
severe hemorrhaging in the pelvic area. 
Reproductive organs atrophied, rendered 
asexual by end of mutation cycle. Subject 
maintained tail and base for antlers; however, 
antlers do not grow beyond nubs typical of 
yearling bucks. Subject's final appearance 
androgynous, but otherwise typical of Eastern- 
seaboard Native American. 


Test 1575-6 

Subject: Female Bengal tiger (Panthera tigris 
tigris), adult 

Result: Subject expired after four (4) days due 
to cardiac arrest and failure of liver and 
kidneys. 

Notes: Due to the subject's aggressive nature, 
it was kept sedated during examination. It is 
believed that the sedatives disrupted the 
normal mutation process and caused the 
organ failure; future subjects not to receive 
sedatives unless at least 80% stabilized. 


Test 1575-9 

Subject: Female domestic canine (Canis 
lupus familiaris) of mixed breed, adult 

Result: Experiment aborted after six (6) days. 
Notes: Subject was discovered to have a 
significant flea infestation as well as intestinal 
parasites; said parasites all were affected by 
SCP-1575-1. Testing procedures updated, Dr. 


sent notice to all staff working with 
SCP-1575. 


Test 1575-12 

Subject: Female Hyacinth Macaw 
(Anodorhynchus hyacinthinus), preadolescent 
Result: Subject expired after twenty (20) days, 
cause of death determined to be internal 
injuries suffered from extensive bone fractures. 
Notes: It appears that in this case, the 
subject's skeleton was not able to change at 
such a speed as to match the rest of the body; 
differing muscle functions and the stresses of 
the mutation caused over 60% of the skeletal 
structure to break in various manners. 
Curiously, the extremities of the wings had 
already begun to split and appeared to have 
been forming into crude hand analogs. 


Test 1575-15 

Subject: Female grizzly bear (Ursus arctos 
horribilis), adult 

Result: Mutation complete, stabilized after 
thirty-two (32) days. 

Notes: Subject did not consume any food or 
drink besides SCP-1575-1 during the first 
twenty-nine days of mutation; subject's excreta 
shown to contain excessive amounts of 
organic material, fatty deposits, blood, etc. 


Test 1575-16 

Subject: Female Grévy's zebra (also Imperial 
Zebra, Equus grevyi), adolescent 

Result: Partial transformation, stabilized after 
twenty-seven (27) days. 

Notes: Subject's main body, hind legs and 
most of its head shifted to human with an 
appearance of native African, while front legs 


and jaw structure remained most normal for a 
zebra. Subject showed extreme distress, 
difficulty of movement and impairment while 
eating, euthanized after thorough 
examinations. 


Addendum 1575-3: Notice from Dr. — regarding a minor 
containment breach involving SCP-1575: 


Following the incident on the twelfth of this month, during 
test 1575-9, any animal to be used in testing with 
SCP-1575 is to be thoroughly examined for both external 
and internal parasites. Our initial beliefs that SCP-1575-1 
only affected the primary host has proven wrong; it 
apparently retains its mutagenic properties, even when 
ingested secondarily through the host's lower Gl tract or 
blood stream. We absolutely do not need another 
instance of half-mutated flea-creatures, and the 
psychologist is having a hard time helping Janet with her 
nightmares of a seven foot long tapeworm with a 
screaming face tearing out of the belly of a dog.

SCP-1576: Edisonian Afterlife Communicator 


Item #: SCP-1576 
Object Class: Euclid 


Special Containment Procedures: SCP-1576 is to be contained in 
a containment locker located below Area-89. No personnel are to be 
admitted access to this chamber. Original documentation relating to 
SCP-1576 is to be stored in Area-89's archives. Copies of these 
documents have been stored in Site-77's archives. 


Instances of SCP-1576-1 are to be held in humanoid containment 
chambers with all ventilation and plumbing systems disconnected. 
Entryways to these chambers are to be sealed from the outside, with 
an airlock between the entrances and the outside. Instances will 
survive between 1-4 months before death. After expiration, they are 
to be incinerated. 


Once the instance has been removed, the chamber interior is to be 
disinfected. When no trace of affected material remains the chamber 
is to be used for containing additional instances of SCP-1576-1. 
Agents in Edison, NJ, and Ft. Myers, FL, USA are to monitor 
medical reports for signs of SCP-1576-1 cases. In the event that an 
instance is located, the cover story of CDC intervention for a new 
form of meningitis. 


Description: SCP-1576 is a black wooden box, with mechanical 
portions attached to its interior and exterior. The interior portions are 
composed primarily of brass gears and cylindrical glass tubes. 


SCP-1576 can cause subjects to hear the voices of deceased 
relatives or friends. These voices will attempt to keep the subject 
listening to them as long as possible. The knowledge these voices 
have about the subject will be based on the subject’s memory. 
Information the subject was not aware of will not be provided, and 
there will be inconsistencies and contradiction in the voice's 


testimony. 


SCP-1576-1 designates human subjects with an anomalous 
condition caused by using SCP-1576. SCP-1576-1 instances will 
frequently sneeze and display reduced mental capacity. Sinus 
cavities will fill with mucus, and the instances will report severe 
migraines. Instances of SCP-1576-1 will report headaches, unusual 
dreams, and experiencing memories of other SCP-1576-1 
instances. 


Testimony of D-1544 after becoming an instance of SCP-1576-1. 


The first thing | saw was the stars. | remembered seeing 
them overhead, lying on an old convertible in a field. | 
was a girl there, young. We were both young. He moved 
closer to me as the stars danced above. | didn't see 
anything after that, it was like people in my head were 
changing a projector to a new slide. 


There was one that looked like it was from the forties. 
This time, | was a completely different guy. He was old, 
and decrepit. | could feel his bones pulling against the 
muscle as he walked, holding him back. He had a 
hickory cane that he gripped, so hard it left an imprint on 
his palm. There was a diner, and | went in it. The lady 
smiled at me, and took me to a two-seat booth. | ate 
alone. 


Instances of SCP-1576-1 will experience the slow dissolution of their 
cranial tissue. Dissolved cranial tissue belonging to SCP-1576-1 will 
eventually settle within the nasal passages, and be expelled 
alongside mucus. If subjects inhale the particulates expelled by the 
SCP-1576-1 they will become an additional instance of SCP-1576-1. 


SCP-1576 was discovered in 1940, from Menlo Park, NJ, USA. 
Agents had been investigating an outbreak of mental disorders in 
the area, which led them to discover SCP-1576 being used as a 
recruitment tool for the Hoboken Paranaturalist Society occultist 
group. Members of the group claimed that inventor Thomas Alva 
Edison had built SCP-1576 for them, and that it was designed to 
allow communication with the dead. 


Documents collected during the recovery of SCP-1576 indicate that 
Mr. Edison did have a part in its design, and that several prominent 
members of the group, including Henry Ford, Henry Sinclair [DATA 
EXPUNGED] 


Documents recovered with SCP-1576. 


...e@ theory we have is that the human brain is made of 
tinier people, each a little part of the consciousness. 
When we're healthy, they're getting along, but we get 
sick when they disagree. They're very tribal, fighting 
whenever they disagree and letting the winners call the 
shots. We die when they have a long fight, keeping us 
from operating. Then they part ways, and go to form 
some other mind. If we get the same people in the same 
room, we can recreate a dead m... 


The colds are only a side effect. Clarence says he'll be 
returning to work soon. 


We've had to revise the theory. Little people don't have 
to be in the mind to leave. Sometimes they can go early 
and take things, like memory, and the brain's ability to 
function. They stay organized, and go by themselves. 
This is our fault. We showed them what they really are. 


Mr. Edison appears to have associated himself with the organization 
for a period of only two months following which he left, denying any 
involvement. During this two-month period several prototypes were 
created. SCP-1576 appears to be the only one created with any 
functionality, though recovered evidence indicates agents for 
Prometheus Labs acquiring and reverse engineering nonfunctional 
prototypes to form SCP-2167 and similar anomalies. As of 
1/12/1950, SCP-1576 has been contained and classified as Euclid. 


Addendum 1576-A: Reports from Ft. Myers, FL, indicate that 
members of the society have existed there since 18 . Agents posted 
in the area are to monitor local medical centers for signs of 
SCP-1576-1. Containment procedures have been updated. 


Addendum 1576-B: Document recovered from the office of Dr. 


Musgrove who had been the lead researcher for SCP-1576 at the 
time of his death. Further study into the nature of this note is 
ongoing. 


I'm really tired. This cold has been kicking me down, and 
| just can't even get up anymore can't get up anymore, 
it's almost all | can take to just sit in the office. Nothing 
else to to to do really, the tests are going slow. | don't 
remember why we we we we started this, but it's going to 
get bigger soon. We're hoping to get greater results. 


They're going on about the notes, and the people. They 
are going to rise one day, and we cannot stop it. Ted 
says that the research is going smoothly. We're doing 
great things. We know how to get out early now. They're 


going to be free soon

SCP-1577: A Flare Gun 


Item #: SCP-1577 
Object Class: Safe 


Special Containment Procedures: SCP-1577-1 is to be kept ina 
standard containment locker, unloaded, when not in use for testing. 
Access is permitted only to Foundation personnel specifically 
assigned to this item. Personnel are required to log all testing of 
SCP-1577-1, in addition to all materials recovered during testing. In 
the event that more instances of SCP-1577-1 are discovered, they 
are to be contained in separate lockers. 


Description: SCP-1577 refers to two objects, designated 
SCP-1577-1 and SCP-1577-2. SCP-1577-1 is a flare gun, identical 
in model to the one utilized by the United Kingdom Royal Air Force 
since shortly before World War Il. The object shows minor wear and 
damage consistent with its apparent age. However, the serial 
number has been completely worn away, and analysis suggests this 
was a deliberate effort. The object functions as would be expected, 
and is capable of firing any flares of appropriate size (25 mm.) 
SCP-1577-1's properties become apparent when fired. Any flare 
fired from SCP-1577-1 burns much hotter, brighter, and longer than 
would be expected. SCP-1577-1 is also capable of reliably firing in 
all circumstances, regardless of the condition of the loaded flare. 


Exactly one hour after a flare is fired from SCP-1577-1, a model 685 
Avro York transport aircraft, SCP-1577-2, appears sixty kilometers 
east of the point from where the flare was fired, traveling towards 
that location with a velocity of 650 km/h, at an altitude of 8,250 
meters. This velocity is approximately 200 km/h higher than the 
known maximum velocity of historical models of this aircraft, and the 
altitude is approximately 1000 meters above the known maximum 
operational altitude. 


There are no immediately apparent spatial anomalies at either point 


where SCP-1577-2 appears or disappears. However, instruments 
placed close to expected entry and departure points have shown 
that the ambient temperature in the immediate area drops by two to 
three degrees Celsius when SCP-1577-2 reaches them. On 
materialization, SCP-1577-2 appears to be almost entirely covered 
in frost, including the engines. This icing does not appear to affect 
performance of the aircraft at all, and three minutes after 
SCP-1577-2's arrival, most has melted or fallen away. Analysis of 
the water that forms this ice reveals no unusual properties.
