Description: SCP-2171 is a seasonal phenomenon involving the 
fallen leaves of all deciduous trees rooted within the confines of 
certain areas (henceforth, "the area").! Leaves fallen within the area 
during seasonal autumn will invariably form large piles that will 
remain unaffected by local weather until all deciduous trees are 
completely defoliated. Piles of leaves affected by SCP-2171 will 
slide slowly, forming "windrows" of varying width. These SCP-2171 
windrows will eventually manifest instances of SCP-2171-1 at their 
front end. 


SCP-2171-1 are humanoid entities composed entirely of SCP-2171 
affected leaves that appear to "guide" the SCP-2171 windrows. 
SCP-2171-1 entities are fragile but capable of movement, yet 
apparently impervious to hostile weather conditions. SCP-2171-1 
emit repetitive vocalizations that may involve speech in various 
languages (see Addendum 2171-02) and have a tendency to hook 
dried leaves on tree branches across the perimeter of SCP-2171 
areas or string leaves between trees that delineate this perimeter. 


Given their behavior, SCP-2171-1 instances are currently believed 
to be sapient. However, SCP-2171-1 instances will only react when 
the integrity of the SCP-2171 windrows they grow from is 
compromised in any way. 


SCP-2171-1 will react violently against any element disrupting the 
SCP-2171 windrows. Such reaction will include various vocalizations 
in a much lower pitch (see Addendum 2171-02), a considerable 
growth in size by drawing mass from the SCP-2171 windrow to 
which the entity pertains and persistent attempts at enveloping the 
disturbing element in a thick cover of SCP-2171 affected leaves. 
Once covered, the element will appear to dematerialize, being 
replaced by a similar volume of fallen leaves. 


SCP-2171's anomalous properties will typically disappear after two 
or three days of continuous activity.

SCP-2172: This Light Never Turns Green 


Item #: SCP-2172 
Object Class: Safe 


Special Containment Procedures: SCP-2172 has been marked 
with a sign indicating its nature and has been the subject of a 
campaign of disinformation by the Regional Press Office, with an 
effort to ensure its status as a “local oddity” and tourist attraction to 
prevent its disturbance. Local Foundation assets are instructed to 
monitor the traffic camera at the location of SCP-2172. In the event 
SCP-2172 turns yellow or green, or any attempt is made to disturb it, 
Local Mobile Task Force 352-Dalet (“Dixieland Nightmare Magic”) is 
tasked with immediate investigation and revision of containment 
procedures, if necessary. SCP-2172-1 is kept in a standard 
containment locker at Regional Headquarters-352. 


Description: SCP-21 72 is a stoplight on northbound Perry Avenue 
in Fort Walton Beach, Fla., that exclusively shines its red signal. No 
attempt, either through traffic control systems or rewiring, has 
enabled researchers to disable the red signal or activate the yellow 
or green signals. SCP-2172’s signal shines regardless of powered 
status, and removing SCP-21 72 from its place at the intersection of 
Perry Avenue and U.S. 98 causes a sharp and immediate drop in 
localized reality levels, which remains until SCP-2172 is returned to 
hang at the intersection. 1! 


SCP-2172-1 is a Field Notes brand 64-page notebook, gray in color. 
Recovered from the home of Warner Davis, a deacon in the Catholic 
Diocese of Pensacola-Tallahassee, after his death by suicide, 
SCP-2172-1 contains a marking of Deacon Davis’s blood and, on 
the adjoining page, a message written by him: 


Asmodei, 


With this blood I 
seal our pact. 


May my soul be 
yours in the 
Second Circle, and, 


In exchange, grant 

my Order an eternal 

flame, a never-extinguished 
light, ensuring the 

victory of the Vatican 

in all wars. 


-Warner Davis 


The date of Deacon Davis’s suicide is concurrent with the first 
recorded manifestation of SCP-2172’s anomalous properties in 19 . 


Addendum: After an extensive internal debate,2 the Foundation 
began the pursuit of testing SCP-2172’s potential secondary effect. 
After over four years of negotiation with the Horizon Initiative and the 
governments of the Holy See and Swaziland, a test has been 
arranged in the Vatican for December ist, 20 . During the test, 
Swazi King 3 will declare war on Vatican City. He and Pope 

will immediately attempt to sign a peace treaty ending the war, 
with no terms beyond an admission of defeat by the Holy See. The 
success or failure of this attempt will indicate whether SCP-2172 has 
any impact on the Vatican’s capability to lose a war.

It is unknown exactly how SCP-247 generates this illusion. There 
are two components to the illusion: first, a memetic effect that 
changes the perceived image of SCP-247 to that of a kitten, and 
second, a psychic component which radiates outward from the 
subject (diminishing according to the inverse square law and 
reaching half strength at meters). Any sentient being within this 
field comes under the impression that SCP-247 is completely 
harmless, regardless of prior knowledge or experience. Individuals 
in this field also show extreme reluctance to harm or allow others to 
harm SCP-247, even while being actively harmed by the subject. 
This psychic field can be blocked with SCP-148, or avoided by 
striking from well outside its effective range. The memetic effect is 
not blocked by SCP-148; as of yet, no one has been able to see 
SCP-247 as anything but a small striped cat. 


Typically SCP-247 will begin to purr or mew when approached by a 
human. The human will remark that this is adorable, and approach 
to pet the subject (this has been observed even in persons who 
strongly dislike cats). SCP-247 has been known to accept affection 
from its victims for upwards of seven minutes before disemboweling 
and devouring them. 


Genetic analysis shows slight deviation from a typical Bengal Tiger's 
genotype, indicating possible contamination [DATA EXPUNGED] all 
further breeding experiments require O5 level approval. The 
resulting hybrids have been designated SCP-247-1; see Experiment 
Log 247a-14 for more details. 


Addendum 247a: A series of tests in exposing SCP-247 and the 
Control subjects to various non-human animals. Control testing took 
place in an exact replica of SCP-247’s enclosure. Control Ais a 
yellow kitten matching SCP-247’s apparent size and age. Control B 
is a fully grown Bengal Tiger matching SCP-247’s actual weight.

chaser.

SCP-2173: An Interdimensional Mexican Standoff 


Item #: SCP-2173 
Object Class: Euclid 


Special Containment Procedures: As SCP-2173 appears to be 
stable, containment procedures are primarily geared to prevent 
public knowledge and interest in SCP-2173. Equipment at 10 meter 
intervals along the edge of SCP-2173 and 10 meters outside its 
edge will automatically monitor interior atmospheric content of 
SCP-2173 and its current diameter. Any change in SCP-2173's 
atmospheric content or diameter are to be reported to Containment 
Site 2173's Director immediately. 


A 0.5 kilometer security perimeter is to be maintained around the 
outer border of SCP-2173. All roadways granting access to 
SCP-2173 are to be barricaded and guarded by armed Foundation 
personnel fluent in American English wearing current US Army utility 
uniforms and equipped with current US Army NBC (Nuclear 
Biological Chemical) protective clothing. Similarly equipped 
personnel are to patrol the established perimeter, which will be 
marked with signs and surrounded with concertina wire. Any 
civilians attempting to gain access to SCP-2173 are to be givena 
cover story detailing an uncontained spill of nuclear waste in the 
area. Class-C amnestics are permitted for use on civilians that 
manage to break the perimeter. Class-B amnestics are permitted for 
use on former residents and friends and family thereof of Dellmarsh, 
Maine. 


All public aerial and satellite photographs of SCP-2173 are to be 
doctored to present consistency with the cover story. 


An aerial robotic probe is to explore SCP-2173 using thermal 
imaging weekly. Any changes within SCP-2173 and all additional 
exploration requests are to be filed with Containment Site-21 73's 
Director. 


Any sign of hostility on the part of SCP-2173-1 is to be negated 
without provoking further hostility. 


Description: SCP-21 73 is an intangible 1 km-diameter dome 
enveloping the majority of Dellmarsh, Maine, United States. The 
atmosphere inside SCP-2173 is approximately 70% carbon 
monoxide, 25% argon, and 5% chlorine and other trace gases. Any 
gases flowing through SCP-2173 are converted almost instantly into 
the same gases as the rest of its atmosphere, and all gases flowing 
out are converted back to Earth standard. Manned exploration is 
impossible because of this. See Initial Exploration Log. 


SCP-2173-1 are sapient, humanoid beings apparently native to the 
environment present within SCP-2173. They have demonstrated 
technological capabilities that exceed that of modern human society. 
SCP-2173-1 instances are bipedal and estimated to be 
approximately 2 meters in height on average. They appear to be 
endothermic. Little else is known about their biology or their culture 
because of the lack of physical interaction between SCP-2173-1 and 
the Foundation.
