On the first day of every month over the course of 24 hours, 70kg of 
shredded chum, raw shrimp and dead fish caught in the region of its 
recovery are to be fed to SCP-1821. Five days hence, any excess 
food is to be removed. Outside of authorized testing, SCP-1821 is 
not to be introduced to any living creature, especially those capable 
of bioluminescence. 


A reservoir is to be constructed near the Site which currently houses 
SCP-1821 according to the following specifications: cylindrical with a 
diameter of 140m, a depth of 10m, and filled with seawater. 
Airspace over the reservoir is restricted to helicams only. Residual 
knowledge of SCP-1821-2 in seafaring folklore is to be suppressed 
and discouraged. 


Description: SCP-1821 is a male omnivorous teleost fish. Genetic 
tests have confirmed the subject as a close relative of family 
Saccopharyngiformes (gulper eels). It is approximately 8m long and 
has a mass of 20kg. SCP-1821's small eyes possess white- 
reflecting retinal tapeta. Aside from its eyes and SCP-1821-1, 


SCP-1821's body has a 99.5% visible light absorption rate2. 
SCP-1821 does not appear to age to a significant degree, if at all. 


SCP-1821-1 is a lure resembling a human mouth and throat which 
extends from the end of SCP-1821's tail. SCP-1821 has voluntary 
control over the motion of SCP-1821-1 — it is capable of opening, 
closing and some vocalization, although it cannot speak. 
SCP-1821-1's lips, teeth and tongue glow with a soft pink light at 
most times and with a brighter red light when SCP-1821 is feeding. 


When exposed to any external source of light radiating in the visible 
range, SCP-1821 reacts by kissing it with SCP-1821-1. This act 
extinguishes and/or nullifies the emitted light. The light source will 
cease to function for the remainder of its existence. SCP-1821 may 
then attempt to consume the extinguished light source with its 
regular mouth. It is unknown whether or how SCP-1821 is capable 
of digesting the various objects it consumes; its spoor is typical of 
the Saccopharyngiformes family aside from size. 


Instances of SCP-1821-2 (formerly Fort-Class Extranormal Event 
RLM-19.39/64-RB) are a phenomenon which occur on or near the 
surface of the nearest body of water to SCP-1821 at least 20m from 
the shore. Instances of SCP-1821-2 take the form of a rapidly 
rotating, horizontal wheel of light measuring between 11m and 114m 
in diameter and between 3m and 8m in height. An instance of 
SCP-1821-2 occurs within 5 seconds of SCP-1821 extinguishing a 
light, and may last up to 10 minutes before descending into the 
water and dissipating. Solid matter cannot pass through instances of 
SCP-1821-2, as they effectively behave towards such as a grinding 
surface with an immeasurably high coefficient of abrasion. Fluids 
pass through instances of SCP-1821-2 easily. Before the recovery 
of SCP-1821, instances of SCP-1821-2 were thought to be an 
independent extranormal event with no discernible cause and were 
responsible for an unknown number of shipwrecks. 


Although SCP-1821 is not confirmed to be sapient, it is intelligent 
enough to have learned a system of several sequences of musical 
tones and to have associated them with objects and events to which 
it has been exposed. It successfully responds by imitating them with 
vocalizations from SCP-1821-1's mouth. This system enables 
communication and has been used by SCP-1821 in order to express 


primitive thoughts. 60% of its communications involve a desire for 
food; 30% involve a desire for being touched; 1% are solitary 
sustained notes with no clear meaning; the remaining 9% are 
expressions of simple emotion, usually sadness when it is not 
feeding. SCP-1821 seems to be unaware of the presence of 
researchers outside its tank; it tends to vocalize directly towards the 
tone generator's speaker. 


On 19 - - inthe , a trench in the Ocean, 8 
instances of SCP-1821-2 were reported within 1km of one another. 
SCP-1821 was recovered uninjured directly below at a depth of 
8.2km. 8 deceased individuals of the same species as SCP-1821, all 
lacking instances of SCP-1821-1, were found in its immediate 
vicinity, as well as a small unidentified wooden wreckage. Cause of 
death was severe radiation damage.

SCP-1823: Rock in a Hard Place 


Item #: SCP-1823 
Object Class: Keter 


Special Containment Procedures: SCP-1823's position is to be 
monitored at all times via satellite imaging and naval 
reconnaissance. All non-Foundation seafaring vessels are to be 
redirected from routes likely to intersect SCP-1823's path. Civilian 
vessels are to be deterred using falsified weather reports. Military 
vessels are to be given rerouting orders from assets in said 
government's navy. If these measures are insufficient, vessels are to 
be detained and forcibly rerouted, and those on-board are to be 
given Class-B amnestics. Should any vessel become victim to 
SCP-1823, aerial support and recovery is to be implemented 
(survivors are likewise to be administered Class-B amnestics), and 
the incident is to be attributed to weather conditions. 


Description: SCP-1823 is an autonomous and self-sustaining 
migratory whirlpool. The dimensions of the whirlpool vary between 
approximately 1km and 4km in diameter, with current speeds of 
100-170kmph. SCP-1823 is capable of "traveling" at a maximum 
observed speed of 30 knots, and often moves contrary to present 
oceanic currents or conditions. There is no observed pattern to 
SCP-1823's path, though it appears to avoid areas with depths of 
500m or less. If, however, any naval vehicle occupied by one or 
more human approaches within 70-300km of the anomaly, it will 
actively target that vessel. SCP-1823 does not track airborne 
vehicles. 


SCP-1823 was discovered on / /19_ in the northern Atlantic 
Ocean, approximately km from the coast of Norway. The discovery 
had resulted in the destruction of a civilian fishing vessel; no crew- 
members survived. The Foundation was alerted following reports of 
the whirlpool's size (presently 3km) and alleged "movement". The 
witnesses were administered Class-B amnestics and the incident 


was publicly declared the result of an iceberg collision. 


Despite Foundation efforts, SCP-1823 has incurred the destruction 
of known vessels and fatalities since its discovery, largely due 
to unpredictability of the phenomenon. Attempts at disrupting the 
currents of SCP-1823 are futile, as this will cause the whirlpool to 
dissipate and reform elsewhere (see Experiment-SCP-1823- 
Perseus for details). Instructions from O5 Command prioritize further 
study of the anomaly, with the aim of establishing neutralization 
protocols or more reliable containment procedures. 


Addendum [1823-001]: Incident Log 

On / /19 at 4:58AM, approximately 550km west of the coast of 
Portugal, SCP-1823 was recorded engaging in previously- 
unobserved activity. The waters of the anomaly became 
uncharacteristically violent, frequently ejecting columns of seawater 
into the air. Said activity increased in intensity over the course of 30 
minutes. 25 minutes after the onset of the event, SCP-1823 began 
to generate shrill, intense sounds of unknown origin’. Digitally- 
enhanced imaging of the event discerned an unknown mass moving 
violently within the water of SCP-1823. Analysis confirms the 
presence of six elongated [DATA EXPUNGED]. A Foundation 
helicopter tracking the anomaly detected several low intensity 
sounds emitted from SCP-1823 one minute prior to cessation of the 
event (see Addendum [1823-004] for details). 


Addendum [1823-002]: Observation Log 

SCP-1823 has been observed to release or generate matter at 
random intervals; how this occurs is unknown. This matter is largely 
composed of flotsam and jetsam, appearing to be of Ancient 

origin, consistent with 700-800 BCE (though it shows no indications 
of decay or deterioration). Human remains have also been 
recovered; these specimens are also consistent with Ancient 

origin, but demonstrate no signs of advanced decomposition, 
despite indications that they would be over 2700 years old. For full 
information on materials recovered from SCP-1823, see 
DOCUMENT-SCP-1823-RM (CLEARANCE 4/1823 REQUIRED). 


Addendum [1823-003]: Incident Log 
On / /20 at 8:34PM, SCP-1823 ejected a living, unconscious 
human being while approximately 780km southeast of Hawaii. Said 


subject was recovered by Foundation naval reconnaissance and 
subsequently debriefed. 


Interviewed: Nathan Richardson 

Interviewer: Dr. Adler 

Foreword: Due to the subject's present lack of 
observable anomalous traits, it is the tentative decision 
of the research team that he be addressed by name. 
<Begin Log> 


Dr. Adler: Do you need anything, Mr. Richardson? 
Richardson: ...No. What year did you say it was, again? 
Dr. Adler: 20 . 

Richardson: ... 

Dr. Adler: What year do you believe it is? 

Richardson: 199 . | was on a...cruise with my family. 
Dr. Adler: What cruise was this? 

Richardson: Bahamas2. 

Dr. Adler: What happened on the cruise? 


Richardson: We were eating dinner in the dining hall. 
My son was eating mashed potatoes; Jason always 
refused to try mashed potatoes, he said they looked 
"icky". Turns out he really liked them. My wife started 
taking pictures of him eating, and that's when everything 
started to shake. The tremors became violent very fast, 
people screamed and ran for the doors. | grabbed Jason, 
but Susan...my wife turned around and the food cart 
came down the aisle so quickly...| couldn't reach her, 
and she wasn't moving, she was bleeding... 


Dr. Adler: You may take as much time as you need. 


Richardson: | got Jason out of there. The ship was 


rocking violently, no one still seemed to know what was 
going on. | figured it was a hurricane, but when | got out 
into the hallway, | saw that there was no wind, rain, 
nothing outside. | ran, trying to find someone who could 
help with Susan, but it was sheer chaos. | yelled, 
searching for anything, then | saw it. The waters, 
churning like I'd never seen before as far as | could see. 
The ship gave a massive lurch, and | tumbled down into 
it with Jason. 


Dr. Adler: Did you try to get back to the ship? 


Richardson: | couldn't. All | remember after the fall is 
blackness. No cold, screaming people or roaring ocean, 
no Jason, just blackness. | don't know how long it lasted: 
it might have been seconds or years. 


Dr. Adler: Do you remember what happened then? 


Richardson: When | awoke, | was standing in...a 
canyon? | don't know what else to call it. It was 
completely circular and massive, almost half a mile 
across. There were these...things erupting from the 
sides of the canyon everywhere, giant sharp rocks, | 
guess. There were also pieces of wood, like parts of 
boats. It was raining, there was mist or something 
everywhere. | couldn't see the bottom of the canyon at 
all, and | didn't see Jason anywhere. Then | looked up... 


Richardson pauses for roughly half a minute, Dr. Adler 
remains silent, waiting for him to continue. 


Richardson: The rocks, or whatever they were, they 
were holding...something up. They dug into the sides of 
it, holding it in place. | think it was asleep...it was just 
stuck there with most of its...heads curled up on top of 
itself. Then | saw Jason. He was hanging from one of the 
mouths. | saw his arm, his hand, his face...then the thing 
shuddered, and Jason fell out, down into the canyon... 


Dr. Adler: Are you alright? 


Richardson: | jumped. Into the pit. | didn't care what was 
down there at that point, maybe Jason was down there, 
maybe he wasn't, maybe he was alive...| just wanted the 
blackness again. | had it, for a while. But then | woke up 
here. 


At this point, Richardson became unresponsive and the 
interview was terminated. 


The subject remains in custody; no further living individuals have 
been observed to be released by SCP-1823. 


Addendum [1823-004]: Post-Incident Analysis 

The low intensity noise captured by Foundation aircraft during 
Incident-SCP-1823-B4 is determined to be a series of vocalizations 
in [REDACTED]. What follows is the known translated transcript of 
these vocalizations: 


-cannot control [UNINTELLIGIBLE] forgive 
[UNINTELLIGIBLE] . 


-sea father commands, must protect, must 
[UNINTELLIGIBLE]. 


-not escape. 


Footnotes 

1. Post-incident analysis indicates that these noises likely belong to 
a living creature. 

2. Foundation records confirm the destruction of a cruise liner on 
course to the Bahamas by SCP-1823 during the indicated year.

SCP-1824: A Mother's Son 


Item #: SCP-1824 
Object Class: Keter 


Special Containment Procedures: Early identification (prior to the 
Expansion State) of SCP-1824 remains a top priority in containment 
of the phenomenon. Personnel are to monitor the United States 
economy and investigate any localized significant recession. 


A series of Foundation vehicles are to patrol the areas vulnerable to 
SCP-1824 and obtain comprehensive photographic data on every 
ground level exterior vertical surface therein. In addition, similar 
imaging programs utilized by online mapping agencies, as well as 
the FBI and NSA are to be tapped and added to the data pool. This 
information is to be processed by a graphic analysis program 
capable of isolating and identifying the designs congruent with 
SCP-1824. 


Should SCP-1824 be discovered, the Foundation is to designate 
SCP-1824-1 as biologically or chemically contaminated, then 
evacuate all individuals that inhabit the area. Evacuated individuals 
are to be housed at Foundation-controlled temporary housing until 
the manifestation has ended. Should SCP-1824 enter the Expansion 
State and total evacuation has not yet been achieved, a gas vein 
explosion is to be emulated to expedite this process. Due to the 
highly public nature of SCP-1824, standard media blackout 
procedures are to be applied. 


Description: SCP-1824 is a phenomenon manifesting as a graffiti 
design composed of red, black, and white spray-paint. SCP-1824 
has thus far only made its initial appearance in urban environments 
with a population density of 14,000/km? or higher in the contiguous 
United States. The graffiti always manifests on ground-level 
surfaces that are vertical or very nearly vertical. Designs produced 
by SCP-1824 are consistent in that they always feature a winged 


female humanoid, and possess a size of 1m x 1m or greater. 
Removing or obscuring the graffiti does not prevent or alter 
SCP-1824's effects. 


All individuals that reside within the effective range of SCP-1824 
(this area is hereafter referred to as SCP-1824-1 and possesses an 
initial radius of roughly 50 meters) will demonstrate a pessimistic 
attitude towards the economy and their own financial situation. This 
effect will result inevitably in financial retention, and steadily worsen 
the economy of SCP-1824-1. Due to this, crime rates and the 
standard of living in said area will increase and decrease 
respectively.
