Addendum 3109-1: During manned expedition to SCP-3109 on 
19102455, The FSV "Tempestuous" manned by 6 voluntary D-Class 
personnel was completely subsumed by SCP-3109-1. 
Transmissions from the Tempestuous continued to be received for 
the following 72 hours, but apparently could not receive any 
transmissions from the Foundation regardless of source. Below are 
selected transcribed portions of those transmissions. 


+ Transmission Log 3109-13 Os - 05m 045s 


D-2953: FUCK! Operating lights up now. '82, 
find me a star or something. 


D-2982: On it. Lights coming up now. ... 
Whoa... 


D-2953: Enceladus, | don't know if you still 
read us, but if you can, we've been straight 
swallowed by whatever the fuck this thing is. 
|... Allah hu akbar, it's beautiful. Like looking 
out into a shattered stain-glass mirror. '82, do 
we have stars? 


D-2982: Nothing yet, skipper. A couple IR 
sources but... it doesn't make any sense. 


D-2971 (over ship's com): Skipper we 
have... We have atmo outside of the ship? It's 
high oxygen and some trace gasses. About 
one-third ATM. | think we can breathe it. 


D-2953: Swear to fuck, if any of you open up 
that airlock, I'm not letting you back in. 


D-2982: Skip, recommend we defrost two or 
three for an EVA to figure it out? 


D-2953: Seriously, what did | just — 


Loud crashing is heard followed by several 
yells. Massive lateral acceleration visible on 
feed. Inaudible speaking continues for two 
minutes before D-2953 is able to reach the 
com. 


D-2953: Enceladus, we just got heavy. Things 
are... Oh come on. Enceladus, we're lying on 
our side on some kind of surface, covered in 
yellow filaments that look like wheat grass. 
And there has to be 200 dogs just chilling 
outside the front window right now. Small, 
brown and white coloring... We're gonna have 
to call you back. | have no idea what's going 
on right now. '82, wake '47 and '48 up here 
we're gonna need— 


UNKNOWN: Enceladus base... Please... 
Someone... (Repeats 5x) 


Afterword: Video feed from the craft's 
exterior, though distorted, is sufficient to 
identify at least 20 instances of SCP-2624-3. 
Additional animate canines are present, but 
fidelity is insufficient to give a positive ID. 


+ Transmission Log 3109-13 O2hr 38m 12s to O3hr 15m 10s 


D-2982: Enceladus this is D-2982... Skipper's 
dead. Or wishes she was. About 20 minutes 
ago, she was... vivisected... by an unknown... 
I'm trying to be professional about this, but | 
can't. We're all gonna die up here. '53 was torn 
to bits by some invisible nonsense. She just... 
Spun apart. All the tiny fleshy bits of her just... 
decoupled from one another. And for a minute 
there, her heart kept beating and her eyes kept 
moving. Her tongue and her... | don't know if 
she was trying to talk. But all of it started 


twitching. Then she spun back together again, 
fell to the deck, and hasn't moved since. I'm 
afraid to touch her. 


Com channel remains open for five minutes in 
complete silence. 


D-2982: We still don't know what happened to 
our EVA, that was almost a day ago. I'm 
gonna go ahead and call them lost. 


Faint barking audible in background. 
D-2982: Dogs are back... 


Audible crying begins. Soft sobs punctuated by 
wailing continue for approximately 10 minutes. 


D-2982: Skipper's alive... Still... Still under 
thrust. If this were any place else we'd be a 
million kilometers away by now but the... the 
background hasn't changed noticeably. Still 
can't see any stars. No closer to the edge. I'm 
hearing some things bounce off the hull every 
now and again, but | stopped caring after | saw 
'65's body floating by... about 20,000 
kilometers across. 


D-2971 (over ship's com): Ready to fire 
those engines, skipper. 


D-2982: ... | gave that order at least 20 hours 
ago. And | am heavy, we're definitely under 
thrust. FuuuuuuuuuuuuU 


Vowel holds for 28 minutes. 

D-2982: -uk this place this place this place. [ 
Depresses ship's com] '71, confirm for me 
we're under thrust... '71, you there? 


10 minutes of silence 


examine long-term survival of the head. 


If long-term survival of the head is possible, further application under 
Project YIN-YANG (Subcategory: Argus-100) will be considered.

1. SeeSCP-3140andSCP-3399for other plant species created via 
Daevite thaumaturgy. 

2. Dr. speculates that tolerance of SCP-392 cultivation might be 
attributed to the decentralised model of Daevite polities in the form 
of the city-state and absolute power wielded by matriarchs in these 
city-states c. 800 BCE. SeeShifts within Daevite civilisationfor more 
information. 

3. Notably, the leading figures of the Wag clan in those regions were 
stated to be of partial human descent and supposedly ostracised by 
conventional Daevite clans. The ostracisation is speculated to be a 
significant factor towards the Waq clan's decline c. 300 BCE due to 
wars with the Qin state.

D-2971: | got you '82. | was just gonna ask 
skipper if you wanted me to fire those 
engines? 


D-2982: ...Sure. Give me .75 G and let's get 
out of here. 


D-2971: HA, don't have to tell me twice! 


UNKNOWN: Maybe we're the ones that aren't 
in the right order. 


D-2982 looks directly at the com camera, and 
remains motionless until feed cuts. 


Afterword: Due to the content of this log and 
subsequent logs, it's very likely that this log 
arrived to the Foundation at least 24 hours 
ahead of the time it was sent. 


+ Transmission Log 3109-13 17h 00m 57s to 17h 39m 15s 


Foreword: This portion of the transmission 
does not appear to have originated from the 
bridge, but from within the EVA equipment 
originally stored on the Tempestuous. Receipt 
of this transmission indicates significant 
distortion of EM radiation within the anomaly, 
and may be responsible for past symptoms of 
radiation exposure noted in manned 
expeditions. Accompanying camera feed from 
EVA-2, worn by D-2948. 


D-2947: '47 check. 
D-2948: '48 check. 
D-2965: '65 check. 


D-2953: And this is Ops, reading you all. Go 
ahead and... Fuck, go ahead and open the 
airlock | guess. 


D-2948: Heh, Skipper's afraid of goofy space 
shit. Skip, didn't you grow up on Mars? Isn't 
this just like... Thursday for you? 


D-2953: Don't start, asshole, you just woke up. 
Shit is literally sideways up here. 


D-2947: Airlock cycling... Done. 


Airlock door opens. View of exterior of craft 
shown through airlock window is inconsistent 
with the view once the door is opened. Outside 
shows very little ambient light, no yellow 
filaments, and no animate canines. Landscape 
consistent with other dwarf planetoids in the 
Kuiper Belt to date. 


D-2948: Wow. Real spooky. | gotta tell you 
Skip, this is super scary. 


D-2947: Leaving the airlock now. '53, we're 
seeing a planetary surface, do you have 
video? 


D-2953: Yes, | do... I'm still seeing dogs and 
wheat grass up here at the bridge. 


All three expeditions members exit the airlock. 
Camera shows a sky full of stars, with 
SCP-3109-1 visible high in the sky. Range 
unknown. Angular size of 15 degrees at its 
longest. Object proceeds slowly toward the 
setting sun. 


D-2965: ...Skipper, you're absolutely sure that 
we're inside of Dash-One? 


D-2953: Yes, I'm sure. | see your feed, | 
don't... | don't know what to think | might be 
some - 


Audio from the bridge immediately cuts as the 
airlock doors cycle closed. Camera view whips 
to location of the airlock. No ship is visible and 
there are no signs of the Tempestuous ever 
having landed behind them. 


D-2965: Skip?... '53? Tempestuous, this is 
EVA team, do you copy? 


D-2948 can be heard beginning to 
hyperventilate in his suit. D-2948 screams. 


D-2947: Oh shit. SHIT. '65 where's the fucking 
ship?! 


D-2965: ...Oh no. 


D-2948: We're dead. We're fucking dead. 
That's it. The air is gonna run out and we're 
gonna die and that'll be the end. 


D-2965 pulls D-2948 to her helmet and speaks 
without opening com. Vibrations picked up by 
in-suit microphone. 


D-2965: You need to calm down. If you keep 
hyperventilating, you're going to run your CO2 
up and blow your scrubber before you run out 
of Oxygen. 


D-2948: Who cares?! What difference does it 
make? We're fucked! 


D-2965: We don't know that yet. It looks bad. 
But we might have options. [ Resumes use of 
Coms ] Ok, first thing, we look for a cave or a 
hollow, and a large rock that'll fit over the 
surface. Second we work on boosting the 
signal of our transmitter in hopes we can catch 
a mining vessel. 


D-2947: What about Dash-One? Any second 


this place could turn into the surface of the 
sun! 


D-2965: Yeah, and it might turn into the Jersey 
Shore, too. That's an unknown. We have to 
deal with what we have. 


SCP-3109-1 suddenly extends in length such 
that its nearest point is directly above D-2948 
at an apparent range of less than 1 km. 
Angular size now in excess of 90 degrees. 
Entity takes on a bright yellow coloration. 
D-2947 and 2948 retreat several dozen 
meters. D-2965 stops and looks up at the 
object. 


D-2965: ...Magnificent... Do you hear that? 
D-2948: '65, don't look at it! 


D-2965: | hear something. It's singing. Do you 
not hear that singing? 


D-2965 suddenly accelerates upward as if in 
free-fall greater than 1 G. Her trajectory 
deflects around SCP-3109-1 prior to D-2948 
continuing retreat. Blue cuboid crystalline 
structures (possibly a copper molecular salt) 
spontaneously form in the surrounding area 
and slowly rise toward SCP-3109-1. Camera 
pans around and large crystal accumulation 
can be seen on the outer surface of the object. 
D-2948 continues retreat, but movement 
begins to slow and strides become shorter, as 
if responding to increased gravitation. Liquids 
of indeterminate composition manifest on the 
surface and rise in small spherical droplets. 
D-2947 drops into a large puddle of opaque 
liquid which settles immediately. No trace of 
D-2947 remains. Distressed vocalization is 
audible from D-2948 as forward progress 


stops and camera angle ascends. 


D-2948: Skipper! Tempestuous! Someone 
answer me! I'm getting pulled into it! 


D-2948 continues to rise above KBO 2448- 
U102. Analysis indicates possible red shifting 
of planetoid surface which is inconsistent with 
observed velocity. SCP-3109-01 structures 
surround D-2948. Ambient light from 
indeterminate source illuminates several 
polyhedral crystalline structures. Red shift 
effect appears to stop. Camera reorients to the 
direction of D-2948's motion. FSV 
Tempestuous Is visible in upper right quadrant 
of feed for 0.3 seconds before suddenly 
disappearing. D-2948 makes sudden contact 
with a surface resembling planetary basalt. 
Vital signs from within the suit no longer 
detectable. 


Camera continues transmitting for 25 minutes. 
Portions of basalt structure crumble and float 
away toward blue crystals resembling those 
collected from the surface of KBO 2448-U102. 
Both materials spontaneously liquefy and 
combine together. Small structures resembling 
the appearance of SCP-3109-01 in an inactive 
state manifest within the solution, and expand 
to consume it. Structures form resembling 
calcite pins on the surface of these instances, 
which suddenly disintegrate and accelerate 
outward in all directions. Five such instances 
develop and disintegrate in view of the camera 
before feed cuts. 


UNKNOWN: Don't come for me. I've made my 
peace.

56h 00m 00s 


Text Description: For the duration of this 
segment, the transmission feed from the 
Tempestuous is replaced by a silent video 
stream of the final 20 minutes of the film 
"2001: A Space Odyssey". Whether this is 
intentional or due to spatial/temporal 
distortions surrounding SCP-3109-1 is 
unknown. 


+ Transmission Log 3109-13 69h 20m 75s to 69h 23m 97s 


Foreword: Transmission appears to be an 
isolated single-camera feed from the exterior 
of FSV Tempestuous. Neither the 
Tempestuous nor its crew are visible. Audio 
transmission appears to be a male human 
voice claiming to be an agent of the 
Foundation which matches no voice printing 
on record. Time stamps of video appear to 
have been anomalously altered to allow up to 
125s per minute during this segment. 


UNKNOWN: Enceladus Base... Please... 
Someone... 


Camera depicts a view consistent with earlier 
views of the interior of SCP-3109-01. Large 
luminous structures similar in shape to 
electron orbitals are visible floating within the 
field. 


UNKNOWN: but I'm not confident. 


UNKNOWN: | don't know if anyone can hear 
me, but if you can... Stay away from Oberon®, 
there's nothing for us here. It's... it's connected 
to 3109 somehow. 


Luminous structures drift toward one another, 
forming ring structures consisting of five or six. 


UNKNOWN: From what I've seen... Whatever 
is down here can do just about anything. | wish 
it made more sense. 


Ring structures collide with other solitary 
floating structures, and attach to the edges of 
each ring at predictable angles. 


UNKNOWN: It's absolutely beautiful but | can't 
figure it out. They're huge. Big as a house. 
What's that... 10 meters across? something 
like that. Like enormous extra-dimensional 
tinker toys. Allah hu'akbar | hope this feed gets 
to someone smarter than me. It's a Foundation 
vessel, so hopefully the transmitter is still 
working. 


Still image from Transmission Log 3109-13 @ 55h 22m 109s 


Large groups of the unidentified structures 
combine in geometric patterns in many parts of 
the field. View is insufficient to be conclusive 
as to greater structure, but structures appear 
to resemble known organic chemicals of some 
variety. 


UNKNOWN: | was separated from my team... 
Maybe they'll make it back with a complete 
report... | don't even know if you'll get this in 
the right order. My memories aren't even in the 
right order... 


Motion and recombination of luminous 
structures continues throughout. 


UNKNOWN: after we landed. They just 
vanished. 


UNKNOWN: Enceladus Base... Please... 
Someone... 


Afterword: Analysis of video feed by organic 


chemistry lab at Site-19 confirms the presence 
of structures analogous to deoxyribose based 
nucleotides. Still attached for reference. 


Proposing we investigate causal and spatial isolation of 
KBO 2448-U102 and surrounding space from the rest of 
the Sol System. The anomaly is dangerous and 
unpredictable, and allowing its continued existence in the 
Kuiper belt has the potential to destabilize future 
prospecting operations, and thereby the existence of all 
extraterrestrial human presence. Mars and Ceres 
included. Attached to this proposal are plans for an array 
of N-dimensional manifold inhibitors capable of 
contracting and isolating the entirety of the current 
containment strata within a standard S-213 causal 
isolation cell. Please consider this option seriously, 
expenses notwithstanding. 


- Jr Researcher Dr. Thaddeus Xyank, Extra-spatial 
Topology 


Proposal rejected by 3-9 decision. There is as yet 
insufficient evidence to suggest that this containment 
would prove to be indefinitely effective. This is beyond 
us. Leave it alone.
