Special Containment Procedures: SCP-129 is at large in the world 
and infects large numbers of humans and animals daily. As such, 
containment efforts are focused on treatment of infected individuals 
and on eradication of any or all member species of SCP-129. 
Although at least 98% of the world's population harbors a natural 
immunity to one or more species of SCP-129, outbreaks that reach 
Stage Three or higher (described below) must be contained as 
quickly as possible, with infected individuals quarantined under 
highest-risk contagion protocols. See Document #129-A-1 for further 
information. 


In the event of Stage Four or Stage Five outbreak, in addition to the 
above procedures, [DATA EXPUNGED}], as described in Document 
#129-A-2 (Level 4 clearance required). 


Description: SCP-129 is a series of at least different species of 
fungus that can infect any animal with mucosal membranes. 
Infection by SCP-129 can pass through up to five stages (depending 
on exposure to further member species of SCP-129, individual 
resistance, and other factors), with each stage of infection facilitating 
progression to the next stage by weakening the individual’s 
resistance to subsequent infection. 


Due to a combination of historical events, most humans and animals 
are naturally immune to SCP-129-04 through SCP-129- . Therefore, 
outbreaks of Stage Three infections are quite rare, but have the 
potential for widespread infection if not swiftly isolated and 
contained. All Known cases of SCP-129 have followed the below 
five-stage progression, although [DATA EXPUNGED], possibly due 
to mutation. 


Stage One: The first organism, SCP-129-01, attacks the victim's 
mucosal membranes, multiplying quickly and unobtrusively. A faint 
yeast-like smell might be detected, but beyond that, SCP-129-01 is 
asymptomatic. A second organism (SCP-129-02) can then infect the 
host, causing the victim to experience symptoms identical to those 
of acute viral nasopharyngitis (the common cold). The decreased 
efficacy of the host's immune system due to infection from 
SCP-129-02 allows SCP-129-01 to become entrenched further. 


SCP-129-01 and -02 generally leave the host body within four to six 
days. Though both species are fairly widespread, and most of the 
population has little to no protection against either organism, they 
pose little danger themselves, except to facilitate infection by 
SCP-129-03. 


Stage Two: Although SCP-129-03 is usually stopped by natural 
mucus, Stage One infection changes the composition of the host’s 
mucus so that the host is significantly less resistant to SCP-129-03. 
Once established in the host, SCP-129-03 alters the host’s mucus, 
lymph, and blood such that other species of SCP-129 can thrive in 
the host. 


Symptoms of Stage Two infection include greatly increased mucus 
production, a nagging cough due to excess phlegm, a lingering low- 
grade fever, increased sweating and salivating, a somewhat 
increased preference for vegetables, and the complaint that certain 
fruit juices 'taste odd’. Infection by SCP-129-03 generally lasts 
anywhere from two weeks to four months before being driven out by 
the immune system, unless the host enters Stage Three infection. At 
least % of all humans have experienced Stage Two infection at 
some point, but due to natural immunities (in spite of Stage Two 
infection) and the relative rarity of Stage Three species, less than . 
% of that % have passed into Stage Three. 


Stage Three: In the absence of SCP-129-03, nearly all animals are 
immune to the three species that cause Stage Three infection. 
However, a small number of Stage Two victims can become infected 
with one or more of these species; in these cases, the fungal 
infections become entrenched in the host and cannot be removed 
without extraordinary measures. 


Individually, the three Stage Three species elicit different symptoms 
in the host: 


* SCP-129-04 causes increased tear production (lachrymation), 
slight yellowing of the eyes, [DATA EXPUNGED]. 

¢ SCP-129-05 [DATA EXPUNGED], causing the host’s nails to 
thicken and significantly increasing earwax production. 

* SCP-129-06 [DATA EXPUNGED], in particular, bright yellow 
urine and small pellets in the host’s feces, both of which smell 
strongly of yeast. 


However, a victim who becomes infected with all three of these 
species will, within hours, develop flu-like (or worse) symptoms and 
become bedridden for three to five weeks. Afterward, though the 
victim appears to have recovered fully, in actuality SCP-129 has 
spread throughout all systems in the host’s body, marking passage 
into Stage Four. 


Stage Four: Victims who reach Stage Four appear generally 
healthy and indeed may be more lively and energetic than at any 
time since first contracting SCP-129. In actuality, SCP-129-01 
through -06 have spread throughout the host’s body, completely 
infiltrating the subject’s immune, respiratory, circulatory, 
reproductive, [DATA EXPUNGED], and central nervous systems. 


Mycelia from SCP-129 species also permeate the host’s skin and 
replace some percentage (up to %) of the host’s hair. These 
hyphae, which are nearly indistinguishable from the host's natural 
hair, are used to propagate SCP-129 to other hosts; any potential 
host that comes into contact with shed-off hyphae has a 9 % chance 
of becoming infected with SCP-129. Hyphae seem to be equally 
contagious from any part of the host’s body, although [DATA 
EXPUNGED] if sexually transmitted due to [DATA EXPUNGED]. 


Despite (or perhaps because of) increased susceptibility to 
SCP-129, Stage Four victims are much more resistant to viral and 
bacterial pathogens than uninfected subjects. All known subjects 
who have reached Stage Four have either progressed to Stage Five 
or died within weeks. 


Stage Five: Symptoms of Stage Five infection depend on a variety 


of factors, including the particular Stage Five species that are 
present, as well as genetic, physiological, environmental, and any 
number of unknown factors. However, as in Stage Four, all Stage 
Five victims are highly contagious and can infect victims who had 
previously shown complete immunity. 


Notable manifestations of Stage Five symptoms: 


February _: Witnesses riding in a commuter train car in [DATA 
EXPUNGED] described a woman suddenly blowing up like a balloon 
and exploding, but instead of blood and viscera, the contents of the 
car were covered in spores and filaments. Analysis later showed 
that the victim was infected with SCP-129-09, SCP-129-14, and 
SCP-129- . All persons and objects in the affected area were 
quarantined, euthanized, and incinerated per protocol; casualties, 
including Foundation personnel. 


May _ : Following a string of disappearances in [DATA 
EXPUNGED] were tracked to a cave several kilometers from town. 
Inside, investigators found several pulsating mounds of flesh and 
vegetative material; although most were unrecognizable, a few of 
the entities retained some human characteristics and were identified 
as some of the missing citizens. 


Researchers theorize that victims of this combination of SCP-129 
would interact normally with the populace, attempting to infect 
others, until, after a period of time, they would come to the cave 
(how and why they were brought here is not known). Upon arrival, 
the victims would be changed into the pulsating vegetative flesh 
mounds, which appear to be organisms modified to provide a long- 
term source of sustenance for SCP-129. Analysis suggests the flesh 
mounds could potentially live for years. Autopsy revealed the 
presence of SCP-129-10, SCP-129-11, SCP-129-14, and SCP-129- 
. Site quarantined and sanitized per protocol; known casualties.

SCP-130: Post Office 


Item #: SCP-130 
Object Class: Euclid 


Special Containment Procedures: SCP-130 is to be staffed by 
twelve D-Class, six security agents (level 2/130) and one researcher 
(level 3/130) twice per day, starting at one half hour before local 
sunrise and sunset. All staff are to be appropriately uniformed and 
Caucasian only. When not staffed, two security agents will remain in 
the lobby, and two additional agents will patrol within the building. 
Agents are advised not to prevent people from entering the lobby, 
but to notify MTF Alpha-4 (“Pony Express”) to intercept anyone who 
receives mail or a package. 


Twice per day, bundles (SCP-130-2) will appear in the mail room. 
The parcels within the bundles are to be sorted by uniformed staff 
into appropriate bags and placed in a designated vehicle for 
transport to Site- . Should mail arrive with the following addresses, 
[REDACTED], follow procedure Franklin-Sixteen, detailed in 
Addendum 130-2. Otherwise, mail will be checked under standard 
practices for any items of interest. 


Objects are not to be placed for outgoing mail unless certified orders 
are given by O5- . Procedure Franklin-Seventeen outlines the 
protocol used in these cases. Should anyone else enter SCP-130 to 
use the outgoing mail slot, they are to be permitted to do so, then 
intercepted by MTF Alpha-4 as soon as possible for questioning. 
The incident is to be reviewed through security tapes and the 
outgoing mail watched for in subsequent bundles and checked 
through the list of previous parcels delivered. 


Description: SCP-130 is a post office in , South Africa, 
constructed in 18 . SCP-130 had been closed in 19 and left 
abandoned for years. The building is in excellent condition for its 
age, and maintains itself without human intervention, including 


moderate structural repairs. SCP-130 has been designated a 
Historic Site through an agreement with the South African 
government. 


Five times per week at local sunrise and sunset, several bags and 
boxes will appear in the mail room. The bundles, designated SCP 
130-2, will show only on weekdays, with the exception of current 
postal holidays for . Bundles are to be handled as per Special 
Containment Procedures as above. 


Inside of the lobby, along with the post office boxes, is a slot labeled 
for Outgoing Mail. The slot is able to accept packages up to 40 cm 
wide and 6 cm high, with no apparent limit for length. Once inserted 
into the slot, packages disappear, and will eventually turn up in the 
outgoing mail bundles, if they have not done so previously. 


Addendum 130-1: SCP-130 came to the attention of the 
Foundation in 19 , when packages and letters began to be 
circulated bearing the postmark for the site. The parcels appeared in 
post offices throughout the world with correct postage for delivery 
either locally or internationally, depending on the parcel. 


The parcels were often undeliverable, either to non-existent 
addresses or to recipients who were not at the address, and so 
ended up in dead letter offices. Various Foundation assets noted the 
odd postmark, and Mobile Task Force Alpha-4 mobilized to 
investigate. MTF Alpha-4 arrived in where they discovered the 
town had mostly been abandoned decades ago. The post office 
appeared to be in excellent condition, not only well-maintained, but 
clean. 


While MTF Alpha-4 searched, bundles of mail appeared in the mail 
room. Agents searched the bundles and discovered a variety of 
letters, parcels, and packages, all with that day's date and the 
postmark for that post office. Agent attempted to open one of 
the parcels, which resulted in the agent vanishing from sight. Six 
days later, a package appeared in Site- 's mail room. Inside of it 
was Agent and an envelope with a receipt for postage due. 
Agent had "Return to Sender" and "Postage Due" tattooed on 
back, and was in a comatose state. Agent remained in that state 
until the envelope was delivered to SCP-130's Outgoing Mail slot, 


where upon the agent returned to consciousness with no 
recollection from the time of disappearance. Similar results also 
occurred when agents tried to take away or damage either the 
parcels or the post office itself. 


Further investigation led to the current containment procedures, 
where Caucasian D-class personnel in uniforms circa 19 

sort through the mail when it appeared. Once processed and put in 
a marked vehicle, the mail can then leave the area 
unmolested. If the bundles are untouched, however, the bundles will 
vanish and later appear in the postal systems of the world in order to 
be delivered. 


Addendum 130-2: Through examination of the mail parcels over the 
past years, research has shown certain trends. Over percent of 
the mail is of a mundane nature, except for the matter of the 
postmark. Exceptions to this are letters that were apparently unsent, 
for whatever reason, and temporally displaced letters. The former, 
while odd, will be destroyed in order to protect the nature of 
SCP-130. The latter will be examined and results submitted to 
[REDACTED] 


Letters addressed to Foundation Sites or Personnel are to be sent to 
Site- where they will be reviewed by Department . Reports shall 
be classified under Project , pending Overseer review. 


Procedure Franklin-Sixteen: When mail is specifically addressed to 
[REDACTED], the mail is to be sealed in a case with active 
countermeasures and brought to the office of the present Level 
5/130 supervisor. Mail will then be screened for possible explosive, 
chemical, biological, memetic or [REDACTED] threats. After 
screening, the mail will be opened and assessed. While no new 
artifacts requiring secure containment have arrived, the possibility 
cannot be ignored. 


Mail either addressed to or intercepted by the Office is often 
temporally sensitive, and as such impact must be minimized to limit 
changes. The possibility of the information being used to alter 
present day events detrimentally must also be weighed. Using the 
information given by SCP-130 to alter events requires a two-thirds 
super-majority vote by the Overseers. 


Examples of intercepted messages are stored within Document 
130-1 and require level 4/130 to access. 


Mail with the following code-phrase [REDACTED] are to be 
immediately delivered after screening, without being read by 5/130. 
After so doing, that code-phrase is to be invalidated, and the next 
one brought in line. 


Procedure Franklin-Seventeen: All outgoing mail is to be sent with 
appropriate current postage for at the time of sending, and 
must be marked with the code-phrase [REDACTED]. The mail sent 
by this method is to be logged, then cross-checked with past parcels 
to insure temporal integrity. 


Upon attempt at mailing should a receipt appear for postage due, 
the amount shall be placed in an envelope and put in the outgoing 
mail slot. The slot will accept the following currencies: Rands, Euros, 
and . The use of counterfeit currencies will result in a lethal 
reaction by SCP-130 and an additional fine will be levied until mail 
can be sent again. 


Addendum 130-3: After the end of apartheid, SCP-130 no longer 
restricts postal staff to be White Only. 


Incident 130-6: On //19 , a package for one arrived with 

the address for a post office box at the site. Dr. _, the researcher 

assigned to SCP-130, placed the parcel into the P.O.B. and waited. 
minutes later, an unknown person identified as 

walked into the lobby. The subject appeared to be briefly puzzled, 

and walked over to the box. The locked box opened at his touch, 

and he expressed surprise at seeing the parcel with his name on it. 


MTF Alpha-4, being on-site, was dispatched to investigate once the 
subject was out of sight of SCP-130, and subsequently interviewed. 
The subject had no plans to visit that day, but had felt an 
unexplained desire to go there while driving nearby to visit family in 
the area. Upon opening the package, [REDACTED]. A Class-A 
amnestic was administered to the subject and was released after 
memory insertion.
