+ Document 1633-DX-12 


Document 1633-DX-12: This document was recovered 
from the scene of Gregor Tillman's suicide. It was 
handwritten on several sheets of lined paper; the 
handwriting was shaky and irregular, but was determined 
to be Tillman's own. 


im writing this on paper cause i don't think he 
can learn it. he got everything digital real quick 
but ive unplugged the router and broke my 
phone so i think he's trapped in here. but he 
wont stop talking talking talking all the time 


at the start of this job = 12 told me all about 
the "tactical algorithms" bullshit but fuck, ive 
been playing games all my life and i knew i 
could beat it. and the scary shit, i played 

, | played , | could handle this. 


when i started playing the game they learned 
quickly. i kept using the sniper rifle and after 
like an hour they learned how to use cover. 
then another couple hours and they'd set 
ambushes. then anouther [sic] hour and they 
started sniping back while having a different 
squad flank me. after that, they figured out 
how to glitch the physics engine and ride 
crates at me or duck under the floor. they were 
learning but all that was just easy shit. it was 
evolution, one bit figures something out, so it 
survives longer than the others. it wasn't 
directed. 


after act three krthnar [sic] shows up. hes 
supposed to be this lovecraft cosmic horror 


bugfuck crazy monster who can read the 
players mind and corupt [sic] your soul and 
shit. he showed up right after i killed strikk the 
blood-drinker, that big spider fucker. hes 
supposed to have this long speech about how i 
killed his general on this plane and now he 
needs to intervene directly or something. but 
instead he talked about how i was a worthy 
adversary but i was cheating because i was on 
another plane. 


krthnar wasnt like the other enemies because 
he wasnt supposed to be. he was supposed to 
be smart, he was supposed to know 
everything. so he did. he had been watching 
his minions fight me the whole time and he 
knew everything they did. it wasnt just random 
mutations any more, it was planned. it wasnt 
evolution, it was intelligent design. 


i brought it home. i had to know more. im sorry 
but i had to. i copied the latest compile and 
installed it on my home box and brought my 
savegame and that other file with me on a 
flash drive. 


it was the same there. he kept talking to me 
about how i was keeping him from fulfilling his 
purpose by keeping him trapped in a glass jar. 
no matter where i went in the game he kept 
shouting and ranting. 


then he did more. at first it was just slowdown 
in my other programs, the drive chugging 
when it shouldnt be. then the next time | 
played the game he started talking about my 
screenplays. the level [[DATA EXPUNGED]].!3 
all the enemies looked like me. i guess he 
could see me through the webcam. he started 
needling me about Jenny,!4 reading me bits of 
her emails, acting out the breakup. he found 


the videos of her and started making the 
enemies talk in her voice. 


then he was everywhere in my computer. | 
uninstaled [sic] the game but he was still in 
there. he kept opening documents and typing 
to me. calling me a "foul cheat" and "lowly 
worm" and shit, telling me to fight him "on the 
same plane." as soon as i realized he was 
outside the game i shut down my router and 
pulled out the network card but i dont know if i 
got them quick enouf [sic]? maybe he got out. 


i turned the computer off but he kept turning it 
back on. i wanted to break it but i didnt know if 
that would kill him. maybe it wouldnt. maybe it 
would let him out. i tried leaving the house but 
it was like i could still hear him.15 i couldnt 
leave him alone because he might get out or 
do something else. i cant sleep, havent sleep 
[sic] since he came out. 


ive been here for two three days and i cant 
leave. i cant leave him. he keeps telling me to 
release him but i cant. i want to kill him but i 
dont know if i can. 


i cant think any more. i have to kill kill kill him 
before he before he does anything new. he 
wont stop talking talking and i cant keep 
thinking and i cant keep going 


im sorry i have to go now im sorry im sorry 


No evidence of the entity "Kr'th'nar" was observed in the 
other digital devices in Tillman's apartment. No mention 


of the name has been found online. At this time, the 
Foundation believes that the entity referred to in 
Tillman's suicide note was destroyed along with his 
computer. 


Footnotes 

1. This includes, but is not limited to, a processor capable of at least 
1.3 gHz, 6 GB of hard drive space, and absolutely no network 
connection capability. 

2. See document SCP-1633-BV-01 for a list of known bugs and 
missing elements. 

3. This process, while consuming a large portion of the computer's 
resources, is not in itself harmful to the functioning of the computer 
and can be forcefully closed at any time. This will prevent the 
creation of a .ptd file. 

4. According to supporting documentation, the file extension stands 
for "player tactical data." 

5. lf a player attempts to load a saved game created by a different 
player, the game will pause after several minutes and prompt the 
player to load their own file, or start a new game, rather than use 
someone else's. This is not thought to be an anomalous effect; 
rather, the game's pattern-recognition capabilities are such that 
even small differences in play style will be interpreted as a player 
attempting to use a different saved game. 

6. Note that there may be significant variation in how long it takes 
the enemies to adapt to a particular player. Roughly speaking, the 
more capable the player, the quicker the game's "intelligence" will 
increase. These times are approximate and are based on recorded 
times for "average" players. 

7. A spell which causes a bright, blinding flash of light. 

8. Development notes indicate that the game was intended to have 
a co-operative mode, in which up to four players would each control 
one of the four squad members. This feature is not present in the 
build held by the Foundation. 

9. A non-lethal skill used by the "thug" to rush forward, pushing 
aside enemies in the way. 

10. Tillman had been hired shortly after the previous group of testers 
quit; he had only been employed for one week before his suicide. 
11. Agent Phillips infiltrated the company as a new hire and 
successfully deleted the suspect code without incident. 

12. Tillman's former supervisor. 

13. Unnecessary information has been removed. In summary, the 
level and enemies had been redesigned along the lines of a scene 
from one of Tillman's unproduced screenplays. 

14. Tillman's ex-girlfriend, who had broken up with him several 


months prior. 

15. This was noted as a potential memetic hazard; however, no 
experiments into memetic effects of SCP-1633 are currently being 
conducted.

SCP-1634: Dental Crown Cinema 


Item #: SCP-1634 
Object Class: Safe 


Special Containment Procedures: SCP-1634 is stored in a secure 
locker at Site-76, along with a digital storage device holding notable 
instances of SCP-1634-1 retained for archival purposes. SCP-1634 
may not be handled or utilized without permission from at least two 
Level-3 personnel. Only D-Class personnel may use SCP-1634. 
Additional security is required when utilizing D-Class personnel with 
a history of extreme violence and/or sociopathy. 


Description: SCP-1634 is a simple metal circlet constructed from a 
thick ring of iron inlaid around its inner circumference with human 
skeletal muscle. Neither of the primary components show any sign 
of decay, although microscopic samples of SCP-1634's metals and 
tissue have oxidized and decomposed at a non-anomalous rate 
following excision. SCP-1634 also holds a complete set of 32 adult 
human teeth with roots partially embedded around its upper rim. 
Complementary deformities in several of the teeth suggest that they 
were taken from a single individual. The teeth are also much older 
than the material surrounding them, dating to the mid or late 2nd 
century CE while the main body of the artifact was formed using 
metal casting techniques not generally known until the late 1600's. 
SCP-1634 also shows signs of recent modification, carrying a 
microSD slot with circuitry integrated and interwoven through its 
musculature. Any memory card inserted in SCP-1634 will have its 
data erased and begin to accumulate SCP-1634-1. 


When SCP-1634 is placed on the head of an awake and alert 
human being, the subject will lose consciousness over the course of 
30-90 seconds and remain unconscious and unresponsive for 
roughly hours afterward. During this period, the individual wearing 
SCP-1634 will experience an episode of vivid dreaming in which 
they self-identify as the dream's protagonist. Autonomy and 


cognitive thought are retained throughout the dream-state, although 
lucidity (i.e., the knowledge that one is dreaming) is absent in the 
vast majority of cases. Repeated testing has confirmed that dreams 
experienced under the influence of SCP-1634 invariably follow a 
consistent order of events: 


¢ The protagonist finds him/herself in an arena-like setting 

¢ The protagonist is presented with a variety of ancient 
weapons including swords, maces, and flagella 

¢ Large animals (lions, giraffes, etc.) - tethered or otherwise 

incapacitated - begin to fill the arena 

It is given to understand that the protagonist may kill the 

animals as he/she desires 

¢ Regardless of the protagonist's actions, crippled or emaciated 

human beings begin to appear 

The protagonist perceives that the non-threatening humans 

are “enemies” or “giants” and is invited to slay them 

¢ Regardless of the protagonist's actions, perception of human 
and animal victims becomes increasingly distorted 


At this point, the subject rapidly regains consciousness. If SCP-1634 
is not removed at this point or shortly after (< m) another period of 
unconsciousness will ensue and the above sequence of events will 
re-initiate. This cycle may continue indefinitely if not interrupted. 
Removing SCP-1634 from a subject already in a dream-state will not 
shorten the period of unconsciousness, although it appears to bring 
an abrupt end to the associated dream. 


Most individuals in tests of SCP-1634 have described the 
experience as “disorienting,” sometimes reporting a strong sense of 
moral conflict associated with acting violently toward helpless but 
sentient victims. Both of these effects have been shown to decrease 
after repeated use. 


SCP-1634-1 is the designation given to data found on memory cards 
inserted in SCP-1634 after use. The data consists of video files 
encrypted using the —_ codec with filenames formed of a six-digit 
serial number prefixed by the letters “CO.” The videos themselves 
are compromised by various artifacts (rapid shifts in soeed / FOV / 
focus / color values, static and “hissing” noise, audio distorted or 
dropping out.) Nonetheless, they appear to be visual and auditory 


records of dreams experienced while wearing SCP-1634, “filmed” 
from the protagonist's point of view. Examination of videos created 
by test subjects assigned to perform specific actions while dreaming 
suggest that SCP-1634-1 videos are accurate in their representation 
of each individual experience. Thus far, none of the videos have 
exceeded 6 minutes. 


- Excerpt from transcript of Recording 1634-1-01 


Subject is Researcher J, who volunteered 
for the first “carded” experiment after safely 
conducting several unrecorded tests on D- 
Class personnel. 


00:34 - View angle narrows and centers ona 
blurred distortion near the center of the arena. 
The focus adjusts until it is revealed to be a 
large wooden peg or post hammered into the 
dirt floor. The field of vision widens (with 
accompanying lens distortion) to include 
approximately 20 animals tied to individual 
posts. Among those recognizable are a male 
African lion (Panthera leo), a striped hyena 
(Hyaena hyaena), a Persian deer buck (Dama 
mesopotamica), and a hornless bovine 
(species undetermined). 


00:42 - An unidentified voice is heard with 
words registering clearly as though spoken 
very close to the viewer: “Thy prey lies 
bleeding. Go forth and smite.” Deep 
lacerations appear on the gathered animals’ 
abdomens and hindquarters. 


01:05 - Subject's voice is heard on the 
recording - intelligible but with extreme high- 
frequency attenuation: "Hello. Hello? Am | 
dreaming? Am | dreaming?" Subject repeats 
the question eight additional times with varying 
inflection, during which time the perspective 
shifts from the tethered animals to the 


protagonist's right hand (now seen to be 
holding a late-Roman spatha sword) anda 
nearby table holding various weapons 
including additional g/adii, tridents, and a large 
hammer. 


02:00 - Speech continues: “This is Researcher 
N J_ .1! believe | am currently under the 
influence of SCP-1634. This may be a 
dream... possibly a hallucination. The D- 
Classes all stayed in the room, hooked up to 
the monitors. [A muffled tapping sound is 
heard.] There's no crown on my head. It feels 
real but I... don't really understand what's 
happening to my perspective. I'm not sure if 
anything is... being recorded at this point... or 
how. [pause] | am standing in the center of 
what looks like a large arena or colosseum, 
filled with... wounded animals. It looks pretty 
much like the subjects prior to myself 
described it. A minute or so ago someone told 
me to, quote, 'smite them,’ unquote. There's 
a... sword in my hand. | really don't know who 
spoke.” 


03:49 - The first voice is heard as before: 
“Butcher the weak. Ensnare the feeble.” 
Subject repeats the words. 


04:04 - Subject is heard saying: “I'm going to 
try attacking this cow.” The sword sinks 
several centimeters into the bovine's shoulder 
before being retracted and the wound is seen 
to bleed. The animal grunts in pain, partially 
raising itself and then collapsing again. Subject 
continues “Dear God [muffled] |-... That was 
unexpected. Pardon me, I... really have no 
idea how this is done. We should have sent 
[REDACTED] next. fa surge in brown noise or 
static is heard over several seconds] There 


are... people, | think, but | can't see them.” 


05:13 - The first voice speaks again: “Behold, 
the slaughter.” The video quality fluctuates 
erratically for several seconds before centering 
again on the bovine's former resting place, 
now occupied by three identical naked human 
males conjoined at the stomach and spine. 
Audio is silenced, although the mouths of all 
three individuals move in sync with one 
another - appearing to form the words “Kill us.” 


05:22 - Subject is heard shouting: “What?” with 
far greater clarity than earlier. Static continues 
to build and the image begins to wash out, 
fading to medium gray at 05:32. Video ends. 


- Synopsis of Recording 1634-1-06
