Special Containment Procedures: The primary superstructure of 
SCP-3813 is located at the bottom of the Tyrrhenian Sea, roughly 
17km southwest of Rome near the Italian Peninsula. Due to its size 
and position on the seabed, transportation is infeasible. 


Further analysis (as well as additional information from third-party 
sources) is necessary to ensure the long-term containment of 
SCP-3813. Should SCP-3813 become active, Site-77 Mobile Task 
Forces are to mobilize to the SCP-3813’s current location and await 
further orders. 


Foundation assets embedded in local maritime law enforcement are 
to prevent civilian access to SCP-3813. Anyone attempting to 
access the SCP-3813 site are to be interrogated. All information 
pertaining to SCP-3813 is to be removed from the historical record. 
The current working cover story can be reviewed in Department of 
Disinformation Datafile 3813.10841 (“Second Punic War: Variation 
6’): 


Description: SCP-3813 is a massive mechanical superstructure 
located beneath the Tyrrhenian Sea near Rome, Italy. While the 
majority of the superstructure is buried beneath the seafloor, a 
significant percentage can be accessed by divers. The interior of the 
structure is a partially submerged network of corridors and 
passageways. 


Historical records indicate that SCP-3813 was a mechanical war 
elephant. SCP-3813 was equipped with a number of antiquated 
armaments, including catapults and ballistae, along with a command 
tower on the back of the structure. The means by which SCP-3813 
was powered is unknown, though investigation of the interior of the 
collapsed superstructure indicates an anomalous design. 


Records pertaining to SCP-3813 have been removed from the public 
historical record by unknown agents in the Roman Republic, Empire, 
and the early Catholic Church. Remaining information indicates that 
SCP-3813 was a mechanical siege engine commissioned by the 
Carthaginian military for use in the Second Punic War. The entity 
stood roughly 375m in height and was capable of carrying a number 
of Carthaginian soldiers and supplies.

The majority of information pertaining to SCP-3813 was 
gathered from a property owned by former Church of the 
Broken God leader Robert Bumaro. The documents and 
artwork were discovered within a sealed vault located 
below the property. Included among the documents were 
receipts of their purchase from Marshall, Carter and Dark 
Ltd, The Journeymen, Wilmington and Associates, The 
Orion Institute, and Kervier International. 


The documents and artwork totaled at 1391 pieces. 
Alongside these pieces were also notes and journals 
written by Bumaro and other high-ranking members of 
the Church of the Broken God. These included 
schematics, diagrams, graphs and other charts about 
SCP-3813 and the nearby region, and long-form 
technical documents about the entity's power source’. 


The majority of gathered information came from three 
notable historians: Aquilla of Naples, Petronius Niccus2, 
and a single unidentified3 individual who claimed to have 
fought the Carthaginians on the shore near Ostia. Other 
minor sources have been identified, mainly collected 
writings from citizens within Rome. 


The first account of SCP-3813 by a non-Carthaginian 
source comes from the records of Adarr of Syracuse, a 


Sicilian merchant traveling to Palermo in 217 BC. 


At the first light of the morning, we were 
awoken by a terrible sound. From our hillside 
we could see the city below us, and the sea 
beyond, and in the far distance stood a terrible 
creature. As tall as a mountain and striding 
through the ocean on legs that could have 
reached into the heavens on their own. It 
hissed and roared and smoked, filling the sky 
with fire and ash. Astride its back was a tower, 
a quarter again as tall as the beast, and | could 
just barely make out men running across the 
battlements. 


When the creature came to a stop near 
midday, we moved towards the beach to see it 
clearer. When the smoke was blown away we 
could truly make out its terrible form; an 
elephant, like those in the south, only 
misshapen and hideous. Surrounding its feet 
were ships flying the flag of Carthage, and 
together they moved slowly through the water 
towards Rome. Even after it disappeared 
hours later, | could still hear the endless 
grinding and screeching of metal. 


A later account, by a Roman soldier traveling north to 
meet the Carthaginians moving south towards Rome, 
described SCP-3813 as such: 


...it is the doom of Rome; the last sound she 
will make will be a scream as she is broken in 
half by a monster that barely recognizes she is 
there at all...” 


The Neapolitan artist Zhaites, who was in Rome during 
Carthage’s attack on the city, described the scene as 
such in his letter to a friend in the north: 


It follows with it a blistering heat, and the air 


around it shimmers and bakes. The sea 
beneath it boils and rolls, those unfortunate 
enough to be caught in it burn. 


Three nights past | witnessed a merchant ship 
attempt to flee the harbor by Ostia and make 
for the open waters south of the colossus. It 
had not but touched the open sea before the 
beast groaned and turned to face it, belching 
fire out of its mouths that set the vessel 
ablaze. 


Now, this colossus sits in the sea, waiting for 
the arrival of an army from the north. The 
garrison has erected catapults, and 
entrenched the shoreline. But what might do 
men have in the face of such unstoppable 
hate? 


The solitary Carthaginian account (outside of Hannibal’s) 
of SCP-3813 comes from a single author, Servius. 
According to Servius, Carthage was not aware of 
SCP-3813 until Hannibal's brother Hasdrubal marched it 
into the city himself. There it was seen as a sure sign of 
Carthage’s inevitable victory over Rome. 


Servius claimed a familiarity with Hasdrubal's son, 
Hyrum. Following Hyrum's death during the battle, 
Servius describes an increasingly desperate situation for 
the Carthaginian forces, including unpredictable behavior 
from SCP-3813's commander, Hasdrubal. The account 
ends shortly after Roman siege weapons drive 
SCP-3813 back into the sea. 


The only supported statement made by Hannibal about 
SCP-3813 is from a conversation he had with Scipio 
many years later while serving as political advisor in the 
Seleucid Kingdom: 


It is said that at one of their meetings in the 
gymnasium Scipio and Hannibal had a 


conversation on the subject of generalship, in 
the presence of a number of bystanders, and 
that Scipio asked Hannibal whom he 
considered the greatest general, to which the 
latter replied, "Alexander of Macedonia". 


To this Scipio assented since he also yielded 
the first place to Alexander. Then he asked 
Hannibal whom he placed next, and he 
replied, "Pyrrhus of Epirus", because he 
considered boldness the first qualification of a 
general; "for it would not be possible", he said, 
"to find two kings more enterprising than 
these". 


Scipio was rather nettled by this, but 
nevertheless he asked Hannibal to whom he 
would give the third place. Hannibal replied, 
"In a different world, one where | had not 
touched the face of darkness, | might have 
said myself, for | as even a young man 
conquered Hispania and led an army across 
the Alps, the first since Hercules.” 


With this said, Scipio smiled and asked again, 
“so then who stands after Pyrrhus of Epirus?” 


“The men who felled Hyperion.” 
Addendum 3813.2: Exploration Log Transcription 
+ Addendum 3813.2 


Note: The following is an audio/video log transcription 
taken from an early exploration attempt into SCP-3813. 
Three members of Mobile Task Force Roma-9 “Ride 
South’, Vanguard, Setrate, and Nereus, were assigned 
to enter an exposed section of SCP-3813 to investigate. 
Audio was recorded from all three agents; video was 
taken from the submersible vehicle and Agent Nereus 
and Setrate’s Independent Video Recorders. 


Agents Setrate and Nereus entered SCP-3813 where the 
front left leg met the main body of the entity. Vanguard 
stayed behind in a submersible vehicle to monitor the 
divers. 


[BEGIN LOG] 


As on-board video recorder comes online, both 
Agents Nereus and Setrate are seen floating in 
the water just beyond the submersible. Beyond 
them is the form of SCP-3813. 


Vanguard: Alright, we’re online. You ready? 
Setrate: You got it. Let’s go. 


Agents Nereus and Setrate swim towards 
SCP-3813. Their access point is a damaged 
panel near the underside of the machine. As 
they approach, Nereus scans the surface of 
the structure. 


Nereus: | hadn’t had a chance to see it up 
close yet. This was built by people? 


Vanguard: That's what they tell me. 


Nereus: Hard to believe something this big 
could move. 


Setrate: (Looking inside SCP-3813) This is 
going to be tight, | think. Stay behind me, and 
let me know if you see anything weird. 


Both divers enter SCP-3813. The access point 
is above the sea floor but barely shoulder 
width in diameter. Both men activate their 
dark-vision goggles and inch forward. 


Nereus: Do we know where this lets out? 


Setrate: Somewhere... inside... there’s a... 
bigger section... bigger than this... (grunts) | 
can barely... move... 


Both agents continue forward for a short time. 
Eventually the space opens up into a larger 
tube, roughly 1 m in diameter. Wedged into the 
wall of the tube, opposite of their entrance 
point, is a large stone. 


Nereus: Explains how our entrance got here. 


Setrate: Let's move up this way. We’re looking 
for... | guess a power supply would be a good 
start. 


The two agents swim up into the pipe. They 
pass small pipes feeding off of the main. 
Nereus pauses in front of one. 


Nereus: Look down there. You see 
something? 


Setrate: Barely... a fish, maybe? 


Nereus: Maybe... let's see if we can get a 
better look at it. 


Nereus activates a head-mounted lamp. It 
illuminates the interior of the smaller pipe, and 
cameras see something moving quickly at the 
end of the pipe. 


Nereus: What was that? 


Setrate: | don’t know. Vanguard, did you see 
that? 


Vanguard: Yeah, I’m looking at the footage 

now... | don’t know, boys, it moved about as 
soon as you turned the light on. Keep an eye 
out. 


Nereus: Roger. 


Continuing forward, audio recorders begin to 
pick up a slow rhythmic sound coming from 
deeper within the structure of SCP-3813. 


Vanguard: You guys hear that? 
Setrate: (Pauses) No... what do you- 


There is a loud, low hum for roughly two 
seconds. The video feeds for Nereus and 
Setrate go dark. 


The electronics inside the submersible begin 
to act erratically. This continues for a moment, 
until all the electronics inside the submersible 
shut off completely. Agent Vanguard launches 
an SOS balloon from inside the submersible 
and waits for assistance. Inside SCP-3813, 
both Agents Nereus and Setrate are 
disconnected. After roughly four minutes, both 
men activate their Independent Video 
Recorders. 


Nereus: Probably just interference. Let’s keep 
going. 


They continue forward until they reach what 
appears to be a valve. Turning the wheel on 
the outside of the door, Nereus manages to 
open the valve and swing it open. The space 
above is open air, but water begins to fill the 
room. They both quickly climb up and slam the 
valve closed. 


The space they are in is a narrow corridor. The 
ceilings are low. Both men crouch to avoid 
hitting their heads. They open the visors of 
their helmets. 


Setrate: Ok, so, not fully submerged. That’s 
good. We can- 


Nereus: Set, look here. 


Nereus points at a wall in front of them, where 
a humanoid figure can clearly be seen merged 
with the mechanics in the wall around it. The 
figure’s eyes are closed and its flesh is rotted. 


Setrate: Shit. Is ita person? 


Nereus: Yeah... it’s not in great shape. Let’s 
keep, uh... keep moving. 


The men continue exploring the tight quarters 
of SCP-3813’s interior for some time. They 
pass by several small side-rooms containing 
discarded machine parts. They see sections of 
the structure that appear to have been 
damaged at some point and repaired. New 
rivets have been placed and leaking steam 
lines have been patched or replaced. Both 
men notice their suit thermometers have 
begun to rise. 


Setrate: It’s getting hotter. (Pauses) | can hear 
something down this way. Hammering. 


Nereus: Let's go. 


They reach the end of a hallway that has 
collapsed. On the ground below them is 
another valve. Setrate opens it and both men 
descend. 


This space is similar to the earlier tube, only 
both men are now descending feet first and 
cannot see what lies beneath them. As they 
shimmy down the tube, their thermometers 
continue to rise. 


SCP-497: The Shell 


Item #: SCP-497 
Object Class: Euclid 


Special Containment Procedures: SCP-497 is to be kept ina 
secure soundproofed room under continuous observation by 
standard security cameras. One guard and two medical personnel 
equipped with high-grade earplugs are to be posted at the door of 
the containment chamber at all times. Only cleared personnel are 
permitted to handle SCP-497. 


If SCP-497 materializes a body, medical personnel are to evaluate 
the subject's health and notify security. If still viable, the subject shall 
be escorted to a medical ward to be processed. Dead or terminal 
subjects are to be analyzed and then disposed of according to 
standard procedure. 


Description: SCP-497 appears to be an Eustrombus gigas conch 
seashell. Recordings have shown that SCP-497 continuously emits 
a very faint sound of voices screaming from within its shell. This 
sound dissipates a few inches away from the object. 


Periodically, SCP-497 will become active and its sound will increase 
greatly in magnitude for approximately one minute. Following this, 
an emaciated human subject materializes, holding SCP-497, and 
then collapses to the floor unconscious or dead. Instances of activity 
under normal conditions have been observed to occur at a minimum 
of two weeks apart, and a maximum of two years apart, with an 
average of four months. SCP-497 has materialized subjects since 
containment began, detailed in Document — . No subjects absorbed 
during experiments involving SCP-497 have been recovered. 


Subjects that hold SCP-497 near their ear and listen to it for more 
than seconds will appear to fall unconscious, and then 
disintegrate. This leaves SCP-497 to fall to the floor. During periods 


Setrate: Fuck me it’s hot, even the walls here 
are- fuck! Don’t touch the walls, shit! 


Nereus: We need to get out of here, we’re 
going to cook. 


Setrate: Can you go back up? 


Nereus: Absolutely not, | can’t even touch the 
walls of the- 


Nereus’ voice cuts out as both men slip down 
the now vertical tube. Setrate lands on a flat 
platform at the bottom, and Nereus lands on 
Setrate's head and shoulders. 


Setrate: Holy shit! | can’t- god, Nereus! I’m 
fucking burning up here, get off- get- 


Nereus: What’s below you? What’s below 
you? We need to get out of here! What’s below 
you?! 


Setrate takes a moment to feel the bottom of 
the platform with his feet. 


Setrate: It’s flat! It's sealed! | can’t, | can’t- 
God, we’re going to- 


Nereus pushes his hands against the side of 
the tube, and his skin begins to hiss. He 
screams in pain and tries to climb back up the 
tube. Nereus's hands slide against the hot 
metal and he falls back down onto Setrate. 
The platform collapses. Both fall into the 
chamber beneath. 


They land on a steel grate roughly three 
meters below. The temperature of the room is 
unsafe, and both men scramble to their feet. 
Nereus inspects his blistered hands, Setrate 
scans the room. 


Setrate: Nereus- there.
