Weather Conditions Prior to Test: Calm, winds east- 
southeast at approx. 5 km/h, light cloud cover 
Observed effects: Six events were recorded during this 
period. Of these, two consisted of new weather effects. 
The first of these lasted for 4 minutes, 10 seconds. A 
cloud of unusual density formed in a structure not 
previously observed on Earth. This cloud was 
accompanied by intense lightning strikes for the duration 
of its existence, and dropped rain, turning to snow, then 
back to rain. The second unique event occurred at the 
end of testing and lasted for 5 minutes. During this time, 
the temperature rapidly dropped in an area that grew to 
0.25 km in diameter at the height of the event, with 
temperatures dropping to -80° C. Water vapor in the air 
condensed and froze, creating a fog-like effect. The 
surface of the ocean also froze within this area of effect, 
to an estimated depth of 1.2 meters. 


Test W-04 

SCP-1149 Conditions: 10 km/h wind, blowing 
perpendicular to SCP-1149 (external fan approved for 
this test), tested for one hour 

Weather Conditions Prior to Test: Winds southeast at 
approx. 15 km/h, overcast, light rain 

Observed effects: Four events were recorded during 
this period. No unique events occurred. 


Researcher's note: This would seem to indicate that 
blowing perpendicularly doesn't have any effect. Though 
perhaps something will be observable at higher wind 
speeds. 


Researcher's note: Test W-06, omitted for redundancy, 
further supports the above theory. Only air that travels 
along the length of SCP-1149 affects its effects. 


Test W-07 

SCP-1149 Conditions: 20 km/h wind, tested for one 
hour 

Weather Conditions Prior to Test: Winds south- 
southeast at approx. 5 km/h, light cloud cover 
Observed effects: Events were continuous during this 
period with many occurring simultaneously. Most were 
not unique, though three were of particular interest. The 
first was a highly dense, rapidly rotating cloud mass. 
After observing its odd color, further analysis indicated 
that it consisted of water mixed with hydrochloric acid, 
abnormal levels of carbon dioxide, and methane. The 
cloud mass was accompanied by frequent lightning and 
a partially formed cyclone. This event lasted for 9 
minutes, 25 seconds. The second unique event was the 
repeated rapid formation and dispersal of an extremely 
low-pressure area, which was observed by the column of 
water that was quickly drawn up into it, then dropped. 
This process was repeated 6 times in a small area over 
the course of 1 minute, 10 seconds. The third unique 
event was a variation of a previously observed event. 
Over an area approximately 20 m in diameter, the air 


temperature rose and quickly peaked at 334° C, lasting 
for a total of 11 minutes. During this time, the surface of 
the ocean vaporized, creating a growing plume of steam. 
This event manifested near one of the observation 
vessels involved in testing, resulting in heat damage to 
part of the vessel's structure and varying degrees of 
burns to each of its crew. The event caused no fatalities 
and the vessel was able to retreat before damage 
became too great. 


Researcher's note: Containment procedures updated. 
With events of this nature, we need a system in place to 
prevent people from entering the area. 


Test W-17 

SCP-1149 Conditions: km/h wind, tested for 27 
minutes 

Weather Conditions Prior to Test: Calm, winds east- 
northeast at approx. 10 km/h, clear skies 

Observed effects: Clouds immediately began to form, 
starting at the center of the cone of effect and spreading 
outward. Cloud composition was determined to be a 
condensed mixture of water with small amounts of 
hydrogen, helium, and ammonia. Lightning strikes were 
frequent, occurring nearly continuously starting at 
approximately 3 minutes. At approximately 5 minutes, 
the temperatures climbed above 90° C, causing the 
ocean within the cone of effect to begin vaporizing at an 
increased rate. Observation vessels retreated and were 
able to avoid damage for the duration of the test. 


At approximately 15 minutes, cloud cover began 
condensing drastically and rotating rapidly, causing 
winds to reach speeds in excess of 400 km/h. At this 
point, the cone of effect had doubled in size due to 
indirect effects and the ocean continued to vaporize at its 
accelerated rate. By 27 minutes, the rotating storm had 
reached 240 kilometers in diameter with wind speeds 
recorded at km/h. Small pockets of extremely high 
temperatures and pressure were observed, resulting in 


ionization of the air and bursts of light and sound similar 
to lightning. Satellite imagery reveals that at this point the 
storm bore a strong resemblance to [DATA 
EXPUNGED]. 


Testing was concluded at this point. The weather effects 
quickly dropped off in intensity, but did not fully disperse 
until over three hours later. The storm made land fall 20 
minutes after the conclusion of testing, but by this point 
clouds mostly consisted of water and caused damage no 
worse than that of a typical tropical storm of mid-level 
intensity. 


Researcher's note: Containment procedures updated. | 
think we can adequately test this thing without going over 
30 km/h. We could've been in trouble if those poisonous 
clouds made landfall. 


Addendum 1149-3: Electrical Testing Log All tests were 
conducted under closed conditions at Site 37. Weather stations took 
readings from Site 37 itself, as well as from vessels located at 
multiple points along the boundaries of SCP-1149's cone of 
influence. When high-accuracy readings were required, a 
geostationary satellite was used. SCP-1149 was under 5 km/h wind 
speeds for each of these tests. The wires leading into SCP-1149's 
base were connected to varying electrical signals. 


+ Show Electrical Testing Log 


Test E-01 

SCP-1149 Conditions: 5 V DC, 0.5 A applied to wires, 
tested for 15 minutes 

Weather Conditions Prior to Test: Calm, winds east- 
southeast at approx. 5 km/h, light cloud cover 
Observed effects: Effects similar to test W-07. Test 
terminated early. 


Researcher's note: A direct current seems to simply 
amplify the effect. No need to prolong the test. 


Test E-04 


SCP-1149 Conditions: RS-232-like asynchronous serial 
communication transmission, transmitting the looping 
output of a simple program, tested for one hour 
Weather Conditions Prior to Test: Calm, winds 
northeast at approx. 10 km/h, light cloud cover 
Observed effects: Effects were especially erratic. 
Multiple events would occur at once and would quickly 
disperse, followed by calm periods. At times, events 
would be grouped together, and at others they would 
have no apparent grouping pattern. Single events 
occurred at multiple points during testing as well. None 
of the observed events were unique. When the timeline 
of observed behavior was compared to the timeline of 
the program's output, no further patterns could be 
deduced. 


Test E-11 

SCP-1149 Conditions: 1 V AC, 60 Hz, 1 A applied to 
wires, tested for 2 minutes, 21 seconds 

Weather Conditions Prior to Test: Calm, winds east- 
southeast at approx. 10 km/h, clear skies 

Observed effects: Immediately after testing began, a 
single event started approximately 25 km (16 mi) directly 
west of SCP-1149. A high-pressure, high-temperature 
pocket formed, vaporizing the ocean beneath it. Much of 
the resulting steam was drawn into the pocket, which 
began to rotate, quickly picking up speed. The cyclone of 
water vapor soon reached a height of approximately 

0.4 km, becoming hotter and denser as it drew more 
water into itself. By this point, wind speeds had 
exceeded 150 km/h. After 1 minute, 30 seconds of 
testing, the cyclone began to emit light. After 1 minute, 
45 seconds, the cyclone had grown to approximately 

1 km high with an immediate area of effect of 
approximately 0.15 km. Observation vessels nearest to 
the cyclone began to retreat due to the danger of the 
extreme light and heat. After 2 minutes, 21 seconds of 
testing, the cyclone was clearly visible with no 
magnification from the observational satellite. The heat 
and electromagnetic field of the cyclone were 


measurable at Site 37, causing multiple containment 
alarms to be triggered. The closest observation vessels 
to the cyclone began to suffer heat damage as they 
continued to retreat. 


At this point, the electric signal was removed from 
SCP-1149, its wires were grounded, and the wind in its 
chamber was shut off. This resulted in the cyclone 
quickly expanding and returning to normal pressure, 
ejecting extremely hot water vapor and super-heated 
liquid water out over a radius of over 8 km, causing 
injuries and 1 fatality to observational crew. The sudden 
expansion also caused a small tsunami, resulting in 
minor property damage along the coast, though it caused 
no civilian casualties. 


Researcher's note: Containment procedures updated. 
We should discontinue this line of testing until we know 
more about what we're dealing with.

SCP-1150: The Passengers 


Item #: SCP-1150 
Object Class: Safe 


Special Containment Procedures: All newly-identified instances of 
SCP-1150 must be cataloged and subject to biannual re- 
confirmation, as per the safe category tracking procedures of the 
Aegis Protocol. All SCP-1150 manifesting in D-class personnel 
should be housed in standard isolation cells or in dormitories 
containing only other instances of SCP-1150. Outside of approved 
testing procedures, D-class SCP-1150 must not be permitted 
prolonged (greater than 15 seconds) touch contact with other 
humans or sentient animals via skin contact or through thin or 
conductive fabrics. Note that this is a cautionary measure only, as 
SCP-1150 can transfer to unwilling or unaware subjects only in 
unusual circumstances, such as those delineated in the SCP-1150 
research log. 


Description: SCP-1150 are sentient entities with human-like 
psychology that share bodies with willing human hosts through 
poorly-understood means. SCP-1150 are aware of all behaviors, 
interactions, and emotional states of their hosts but cannot usually 
perceive individual thoughts or memories. They appear to be 
immune to all amnestics, excluding a slight susceptibility to ; 
which is likely due to neurological damage to the host at high doses. 
While the host is conscious, there is no known means of detecting 
the presence of SCP-1150, save for the occasional brief appearance 
of anomalous REM-like EEG traces in some subjects (namely sleep 
spindles and K-complexes). The Foundation currently tracks 38 
instances of SCP-1150, maintains 3 instances in D-class personnel 
for testing purposes, employs 2 instances (along with their hosts), 
and maintains one instance in Level 3 confinement for security 
reasons. 


When the human host of an instance of SCP-1150 falls asleep, they 


immediately enter REM (dream state) sleep and the SCP-1150 
entity gains control of the host body for a period of 5-16 hours. This 
duration varies with the mental fortitude and willingness of the host 
and the relative strength of the entity. While the SCP is in control, it 
acts, behaves, and generally has physiological reactions identical to 
those of a normal human, albeit one with memories and personality 
traits different from those of the host. At the end of its period of 
control, SCP-1150 becomes sluggish and appears to sleep. One to 
two minutes later, the host awakes and regains control of their body. 
Hosts generally report that they are fully rested and are generally 
unaware of what has transpired while they were asleep. Note, 
however, that individuals who have hosted SCP-1150 for prolonged 
periods (several years or more) become gradually more aware of 
the actions of their "passenger". 


SCP-1150 can be transferred from host to host through physical 
contact. While it appears that almost any skin-to-skin contact is 
sufficient to transfer SCP-1150, direct forehead-to-forehead contact 
allows for transfer times as low as 15 seconds. Conversely, transfer 
takes approximately four minutes via hand or foot contact. If the 
contact is disrupted at any point during the transfer, the entity 
remains in the original host. Recipients of SCP-1150 report a 
"pleasant buzzing" sensation and exhibit a slightly elevated stress 
response but appear otherwise unaffected by this transfer. In all 
instances, save those documented in the attached experiment log, 
the recipient of SCP-1150 must be willing to accept the entity. There 
are no known means for destroying an instance of SCP-1150, 
though they can be incapacitated indefinitely by killing and interring 
the host. 


The Foundation first became aware of SCP-1150 on 6/27/1982 
shortly after the FBI raid on the Kismet Doorway cult in Bloomhill, 
Arkansas. Foundation sources within the Bureau learned of a high- 
ranking cult member in FBI custody with potential SCP properties. 
The Foundation arranged a transfer to Site 40 due to its proximity to 

, and there conducted the initial interviews with the entity, 
currently classified as SCP-1150-1. SCP-1150-1 subsequently 
assisted in the identification of three additional instances of 
SCP-1150 associated with the Kismet Doorway. 


Addendum: On 12/10/2008, the recovery of sensitive documents in 
a raid on Marshall, Carter & Dark Ltd. indicates that MC&D are 
currently employing at least two instances of SCP-1150 to infiltrate 
the Foundation as "sleeper agents" to obtain classified information 
on SCPs and Foundation security. These entities are being carried 
completely unknown to the SCP employee hosts, and are able to 
see, hear, and experience everything that the host does. It is 
unknown how these agents are getting information back to MC&D, 
given that Foundation research has not revealed any outward 
manifestations of SCP-1150 when they "piggyback" on an unwitting 
host.
