Upon playing of entirety of aloum, subject 
reports hearing 2 minutes and 35 seconds of 
an unidentified movement played by 
symphony orchestra. Movement is described 
as atonal in the treble portion, but with a clear 
harmonic chord progression that are atypically 
somewhere between diminished and 
suspended in form. Unlike other instances of 
SCP-1668, the record does not include this 
movement. 


Handwritten note attached to vinyl record 
resembles other notes from POI-1668-1 
("Erich Zann"). Note reads as follows: 


[BEGIN NOTE] 
Dear SCP Foundation, 


| fear | may have become lax in my 
presentation, but | am not quite sure how to 
classify my latest discovery. | had realized that 
a strict forward chronological progression led 
to a limited possible slate of results. Working in 
reverse, | discovered this haunting melody. | 
tried recreating it for the record, but a 
combination of the complexity of the piece 
along with its use of notes outside the 
chromatic scale made it impossible to 
duplicate. Perhaps you will have better luck. 


It does resemble something by Stravinsky or 
Shostakovich at first blush (if you will please 
excuse the conflation) and yet, I'm struck at 
how it almost fits with early opera, as if it were 
written by Jacopo Peri. | do know | have never 
heard it before. 


Yet something tells me I've heard it multiple 
times. 


In bewilderment, 
Erich Zann 


[END NOTE] 


MTF Zeta-4 Agent Mike Carter has listened to 
the album and generated an audio file that 
recreates the ideated music. Final testing of 
this phenomenon involves playing the audio 
file at the conclusion of vinyl record playback 
to confirm the music heard by test subjects. 


Researcher's Note: Agent Carter has no recollection of 
creating or playing the audio file. 


| also was no longer in Zeta-4 at the time. 
Don't know why I'd have been experimenting 
with sound files then. 


— Agent Mike Carter, MTF Eta-11 


+ DISCOVERY NOTE / ACCESS RESTRICTED TO MTF H-11 MEME 


| know this is an unorthodox use of the 
database, but | need to do this for my peace of 
mind. 


Mike, and anyone else who might decide to 
join this old team, long in the tooth, | just need 
to make some notes on what happened in 
Garnya. Yes, we set up surveillance, we 
traveled out to Bulgaria, found the village, the 
musicians, let Zhao lead us into the 
mountains, all that. Beautiful place, Garnya. 
Seems lost in time. Took a while to make sure 
the Silencer was in place, we had recording 
equipment available, all that. We needed to 


capture the phenomenon. We had to be ready 
to make a snap call, rush in, stop the music, 
and pull everyone and everything out. 


| was supposed to be the lead on this. I'm 
deaf, so, it was figured, the anomaly wouldn't 
work on me. We didn't yet know it was 
acoustic, more physical in nature, and not 
some other method. But that's the risk we 
MTFs take every day, so, welcome. 


| ran in to stop the performance, got 
disoriented when | hit the sound pressure, the 
musicians saw me, the music stopped, and 
Zhao and I, not knowing what was happening, 
stuck to training and retreated. 


| needed a rebriefing on what happened. | 
completely forgot. Thank God we have the 
surveillance footage. That surveillance footage 
was key for myself and Zhao. It meant that we 
could try again. We kept the cave entrance 
guarded so the musicians couldn't escape. We 
couldn't wait any longer. We rushed in again. 


We rushed in five times. 
On the fourth run, | died. 


We realized we couldn't approach the 
musicians without them playing their song and 
making us forget why we were there, and so | 
apparently hatched a cockamamie plan to just 
collapse the cave and trap the musicians 
inside instead of trying to approach them. 
Sounds like the sort of stupid thing I'd do. 
Sure, the cave had been recently painted to 
resemble Paleolithic drawings, but the soot 
was still so fresh you could smell it. It's not like 
| was burying some archaeological treasure. 
So | went to the cave entrance, set charges, 


and... 


Well, | always let my anger get the best of me. 
| didn't check and the charges went off 
prematurely, collapsing the cave, with the 
musicians inside, and me, crushed under the 
rubble. Of course, the musicians just used the 
only weapon they had, that piece, and played 
it as loudly and fervently as they could. The 
wall of sound must have hit the rubble hard, 
because, according to the footage, the 
boulders pulled themselves back up into place 
in the walls, fixed themselves. The explosions 
imploded. And | just got back up and took 
down the charges and returned to base. 


Try not to catch yourself dying on camera. | 
thought losing my hearing was bad. As far as 
I'm concerned, one moment, I'm heading out 
of Garnya to the cave, and the next moment 
I'm being placed in front of a monitor, being 
told not to blow myself up again. All those 
events in the middle, there's nothing. 


Richards grabbed the Silencer and rushed in, 
guns blazing, moments later. Zhao told me the 
music had stopped. He came back out of the 
cave covered in some goopy, bloody film, | 
don't know what, with some sheet music and a 
baby. 


You want to know the weirdest thing? I've 
never heard the music. Duh, you're thinking, 
deaf guy. But no, from a temporal point of 
view, I've never heard the music. I've never 
been exposed. 


But when | dream, | do.

SCP-2403: The Air Stair 


Item #: SCP-2403 
Object Class: Safe 


Special Containment Procedures: The east stairwell of 
Research Site-—45, between the 1! and 3" floors, is to be closed 
to personnel indefinitely. Access to the 29 floor landing will be 
blocked with reinforced concrete with a steel blast door on the 15! 
floor landing to be locked at all times. Testing on SCP-2403 has 
been suspended until further notice. 


Description: SCP-2403 is a phenomenon currently isolated within 
the east stairwell of Research Site-45, between the last step of the 
stair flight of the 2" floor and the 2 floor landing. Whenever a 
sentient bipedal being descends the stairwell and crosses over the 
last step of the 2" floor, they will be instantly transported to another 
location in space-time. 


In all cases, the locations are observed to be mainly areas of high 
altitude with abrupt vertical cliff faces. Any subject transported by 
SCP-2403 will be positioned to step and fall off these cliff faces, 
regardless of any foreknowledge of the phenomenon. Subjects will 
experience free-fall at a normal rate during this phase. Before 
making contact with the ground, subjects will be instantly 
transported onto the 2¢ floor landing. 


Subjects will experience a slight time dilation effect as the time at 
the point origin from when they disappear and reappear is nearly 
instantaneous. However, subjects will experience the full duration of 
the free-fall and retain a memory of the event. No other physical 
objects or properties have been seen to return with the subject such 
as rainwater (if applicable), dust particulate, gas trapped in the 
subject's lungs, subject's inertia, or subject's momentum. Testing 
has proven that there is a correlation between stairs traveled ina 
single stride with locations, although the precision of these results is 


currently inconclusive. 


[LEVEL-2 ACCESS REQUIRED] 
Experimentg441-1-1 


Subject: D-9679 

Procedure: Subject is asked to descend 
SCP-2403 at a normal pace while wearing a 
portable video recorder. 

Observation: Subject descends the last step 
normally. Upon making contact with the 
landing, the subject starts screaming ina 
panicked state. Subject remains in a panicked 
state for five seconds before appearing 
disoriented and then stumbling toward the 
adjacent wall while breathing heavily. 

Video Analysis: Video captured a full 5.5 
seconds of free-fall footage with the subject 
screaming for the entire duration. After 
stabilization of the video was applied, the 
location was confirmed to be a bridge possibly 
in the western United States. Bridge is 
positioned over a gorge estimated to be 350 
meters in depth. Based on a structural analysis 
of the bridge, it is thought to have been built 
within the last 30 years. 


Experimentq441-1-3 


Subject: D-8755 

Procedure: Subject is asked to descend 
SCP-2403 at a normal pace while wearing a 
portable video recorder. Subject is also 
instructed to jump over the last step and onto 
the landing. 

Observation: Subject descends and makes 
the jump over the last step. Upon making 
contact with the landing, the subject collapses 
in an unconscious state. Subject is treated in 


the infirmary for sudden cardiac arrest and 
revived. During the debriefing, subject has no 
detailed memory of the event other than the 
sensation of falling. 

Video Analysis: Video captured a full 18.9 
seconds of free-fall footage with the subject 
believed to be only conscious for the first 5.8 
seconds. Analysis of the video was able to 
identify several important landmarks that were 
able to confirm the location as the Store 
Trolltind, which is Europe’s highest cliff. Date 
at the location was unable to be determined. 


Experimentq441-1-7 


Subject: D-1145 

Procedure: Subject is asked to descend 
SCP-2403 at a normal pace while wearing a 
portable video recorder. Subject is also 
instructed to jump over the last three steps and 
onto the landing. 

Observation: Subject descends and makes 
the jump over the last three steps. Upon 
making contact with the landing the subject's 
body, now dead, collapses. An autopsy 
performed showed the cause of death to be 
sudden depressurization as most of the organs 
and skin tissues were ruptured. 

Video Analysis: Video captured a full 1.1 
minutes of free-fall footage with the subject 
believed to be alive for an estimated 10 
seconds. Analysis of the video was unable to 
confirm a terrestrial location. Further video 
analysis in conjunction with the autopsy report 
posited the location to be on the planet Mars, 
possibly along the high cliffs surrounding the 
Echus Chasma crater. Confirmation is pending 
following further review of this data.

Item Description: "Mr. Leaven's Yeast, Nacho Cheese Flavored": A 
small yellow aluminum bag containing what appeared to be active 
dry yeast, packaging in American English with a southern dialect. 
On consumption of a handful, D-11196 reported that they tasted 
"Just like Doritos". Hours later, subject complained of abdominal 
pains and mild drunkenness, typical symptoms of pure yeast 
consumption due to sugars in the stomach breaking down. Subject 
recovered normally.

Item Description: "Fractal Flakes": a small box of cereal, packaging 
in American English. Resembles other "corn flake" based cereal 
products, albeit with each flake having an intricate fractal pattern 
engraved on it, a small note was included warning to only eat one at 
a time. After consumption, subject reported feeling uncomfortably 
full. Feeling remained for next 8 hours. After testing with placing a 
flake in a jar of water, the flake exponentially grew in size to the 
approximate capacity of the human stomach. Fractal pattern 
observed to fade as flake grew. 


Money entered: 500 Yen 

SCP-261 Powered or Unpowered: Unpowered 

Item Description: "jRevolution! Energy drink" 250 ml red and black 
striped can, text in Spanish. Drink was heavily carbonated and 
tasted of citrus. After consumption by D-12587, subject climbed atop 
a nearby table and began aggressively shouting anarchist slogans, 
before engaging in a physical struggle with a guard. Subject 
terminated. 


Money entered: 500 Yen 

SCP-261 Powered or Unpowered: Unpowered 

Item Description: 20 oz glass bottle of "Barrett Cola". No label; 
product name is laser-engraved into the glass. Glass is opaque, 
preventing external viewing of the interior. Opening the bottle 
causes it to fire one .50 BMG round in the direction that bottle is 
facing. Putting the cap back on will "reload" the bottle, causing it to 


Subject: D-5984 

Procedure: Subject is asked to descend 
SCP-2403 at a normal pace while wearing a 
portable video recorder and a NASA Z-1 
spacesuit. Video recorder has been upgraded 
to be able to function in hostile environmental 
conditions. Subject is also instructed to jump 
over the last half of the flight and onto the 
landing. 

Observation: Subject descends and makes 
the jump from halfway down the flight. Upon 
making contact with the landing the subject's 
body shatters inside the suit. The remains of 
the subject were observed to be frozen solid 
and the suit appears to have been torn along 
the right leg. Video recorder unit was 
damaged, but intact. 

Video Analysis: Video captured a full 12.2 
minutes of freefall footage. After 5.1 minutes of 
free-fall, the subject experiences a hard impact 
against the wall, rupturing the suit. Death 
occurred 23 seconds after this event. Analysis 
of the video showed a low gravity environment 
in extreme cold conditions. Footage also 
reveals the entire surface to be solid ice. 
Comparing certain sections of footage looking 
up at the sky with known star charts, it is 
determined that the location is located outside 
of the known local solar system. 


[LEVEL-3 ACCESS REQUIRED] 
Experimentq441-1-11 


Subject: D-2469 

Procedure: Subject is wearing a portable 
video recorder and a NASA Z-1 spacesuit. 
Video recorder has been upgraded to be able 
to function in hostile environmental conditions. 
Subject is instructed to jump over the flight of 


stairs and onto the landing below. 
Observation: Subject makes his hesitations 
known to the researchers and security present. 
Subject is assured that any injuries sustained 
from the fall will be treated in the infirmary. 
Subject continues to be uncooperative. The 
security team present then convince the 
subject to participate. Subject makes a running 
start on the landing above and jumps to the 
landing below, successfully clearing the entire 
flight. Subject disappeared right before making 
contact with the bottom landing. No sign of the 
subject or the video recorder unit exiting was 
observed. 

Video Analysis: Inconclusive pending 
retrieval of the video recorder unit. However, 
an adjacent lab detected a burst of beta 
radiation on-site at the exact time the test was 
conducted. Data has been logged for further 
review.
