Despite the loss of resources and personnel due to this experiment 
something productive came from it. If we can figure out how this

Addendum 3720-02: Following Interview 3720-01, it was decided 
that Researcher S be transported to an off-site safe house to 
minimize the risk towards other Foundation staff while MTF 
Upsilon-8 ("Adherents") attempted to contact Entity of Interest 
3720-1 ("Velkai"). Upsilon-8's attempts were unsuccessful, and over 
the course of the next several weeks, SCP-3720-1 staged multiple 
assaults on the safe house, all of which were thwarted by security 
personnel. No Foundation casualties were sustained during this 
time. 


On 06/03/2006, despite the lack of nearby fault lines, an earthquake 
(estimated magnitude: 7.0-7.5) decimated the safe house, killing 
Researcher S and four of the six assigned security staff. The 
earthquake was localized entirely to the safe house and 
approximately 1.5 square kilometers of the surrounding forest. 


SCP-3722: The City That Was Half the World 


WARNING: This article, along with all information about SCP-3722, 
contains an infohazard which prompts an amnestic effect in all who 
read it. After you have read this article, you will be unable to retain 
the majority of the information contained within; all researchers on 
SCP-3722 must take an appropriate dose of mnestics after reading 
this article. 


Item #: SCP-3722 
Object Class: Keter 


Special Containment Procedures: A method of preventing 
SCP-3722 has not yet been found. Due to the amnestic effect of 
SCP-3722, only personnel who have subsequently taken mnestics 
can recall any information about SCP-3722 or any SCP-3722 
events. This effect has thus far protected SCP-3722 from public 
exposure. 


Due to the unstable nature of SCP-3722, it is possible that its 
amnestic effect could fail in the future. Should this occur, Operation 
Caesar's Spider is to be launched to artificially prevent public 
knowledge of SCP-3722. In order to prevent a further degradation of 
SCP-3722, Foundation agents have been embedded in the planning 
departments of Isfahan's municipal authorities. They are to prevent 
any alterations to the city and its landscape which could further 
destabilise SCP-3722. 


Due to the ORIA not possessing any mnestic capabilities, it is 
believed that the organisation is unaware of SCP-3722. Preventing 
ORIA from gaining mnestic capabilities is considered to be of vital 
importance. Informing ORIA of SCP-3722 is part of the protocol for 
Operation Caesar's Spider, in order to enlist their aid in containing 
the anomaly and preventing exposure. 


Observation of SCP-3722 is to be performed via remote drone, as 


any humans entering SCP-3722 will become SCP-3722-1 instances. 


Description: SCP-3722 refers to an event taking place in the city of 
Isfahan, Iran, on 13 Muharram each year according to the Hijri 
calendar. Beginning at sunrise, and finishing at sunset, the entire 
structure and layout of the city metamorphosises into a near- 
identical copy of itself from an earlier point in its history. SCP-3722 
always emulates the city at a point prior to 23/10/1722 (13 
Muharram 1135 in the Hijri calendar);2 ordinarily, this will be at a 
point between the 1610s and 1670s.3 The precise scenarios which 
occur are believed to be thematically linked to events taking place in 
contemporary Iran. 


The inhabitants of the city also abruptly transform, with their clothes, 
visual appearance and personalities altering to match the period and 
location which SCP-3722 is emulating. These individuals are 
henceforth referred to as SCP-3722-1. SCP-3722-1 instances act in 
a period-appropriate fashion, taking on jobs and roles necessary for 
the functioning of the city in the period emulated. Any individuals 
entering the city during SCP-3722 will also become SCP-3722-1 
instances. Any non-human objects entering the city will not 
transform after the beginning of the event, however, which can often 
cause confusion among the SCP-3722-1 instances who encounter 
them.4 


At dusk, the city abruptly collapses into rubble. Following this, 
SCP-3722 ends, and the city returns to its ordinary, non-anomalous 
state. The SCP-3722-1 instances transform back into ordinary 
individuals, who possess no recollections of SCP-3722; their 
memories will compensate by constructing alternate scenarios about 
the day in question. The same will occur for any outside observers, 
or any individuals who learn about SCP-3722 through second-hand 
means. The only known way to counter this memory-loss is through 
the use of mnestic compounds. 


It is unknown how long SCP-3722 has been active, but it is 
speculated to have begun shortly after 23/10/1722 (13 Muharram 
1135 in the Islamic calendar). It was discovered by Foundation 
personnel on 13/12/1978 (13 Muharram 1399), shortly after the first 
discovery and implementation of modern mnestics.

SCP-483: Anti-Aging Placebos 


Item #: SCP-483 
Object Class: Safe 


Special Containment Procedures: SCP-483 needs no special 
containment, other than to prevent use outside of authorized testing. 
SCP-483-1 is not to be administered to subjects for whom there 
exist living humans outside the Foundation who are significantly 
acquainted with the subject and aware of the subject's age. Under 
no circumstances is SCP-483-1 to be administered to those known 
by Overseers. If SCP-483-1 is to be administered to a subject ina 
quantity in excess of their original age (see Addendum 483-b), all 
documents detailing and suggesting the test should exclude any and 
all information about the subject in question, especially the proposed 
original age to be tested; information recorded from and for these 
tests should not be taken from the subject directly, but rather from a 
clone of the subject created using SCP-222 (using a double-blind 
procedure), until all tablets designated for the test have been 
successfully administered. In cases where the subject is an 
SCP-222 clone created for this test (the recommended procedure), 
the original may be used for initial records. 


Description: SCP-483 is a standard orange prescription bottle filled 
with up to 50 spherical, gray tablets (SCP-483-1). The label 
indicates that it was issued to a "Sherman, David A.", and in place of 
a prescription name, the label reads "anti-aging". The remainder of 
the label has been torn off. Analysis of the tablets shows that they 
are chemically identical to placebos. 


When SCP-483-1 is ingested by an organism possessing a stomach 
capable of digesting medication, its effect takes place: All existing 
memories, documents, and records regarding the organism's age 
are altered, decreasing the organism's recorded age by one (1) full 
year. All numerical values/memories relative to the organism's age 
are altered correspondingly. The ingesting organism displays no

Addendum 1, 01/10/2011: On 08/09/2011, Foundation historians 
discovered a single damaged page of a Safavid-era letter in the 
Ottoman Imperial Archives. The writer and recipient are unknown, 
but the letter was dated to after the Treaty of Constantinople 
between the Safavids and the Ottomans in 1590. The letter begins 
and ends mid-sentence, and has suffered extensive water damage. 
A translation from the original Persian is as follows: 


as your second Solomon can attest to®. May this peace 
last a thousand years! For the hostilities between fellow 
Muslims are to be deplored; the Dar al-Islam’ must 
remain united. 


| speak to you now on a more fascinating and terrible 
subject; Our Shah's plans for the reconstruction of 
Isfahan. He has taken a strange step; he has elected not 
to alter the old city of Isfahan, with no changes being 
made to its houses or mosques. Instead, our glorious 
monarch has conceived of the creation of an entirely new 
city, built slightly away from the old city. The plans he 
has presented are almost perfect in their form and 
function; he would create a single long boulevard, 
flanked by beautiful houses, gardens and trees. This 
would lead past the palatial complex, onto which it would 
open. On the other side of the palace

consulting with various alchemists and physicians in its 
design. Its perfection goes beyond the mere 
requirements of the city, but is instead designed to 
simulate a particular alchemical representation of the 
human mind. The city would have a life of its own; its 
call, subliminal and strange, would possess a grand 
memory of the past and a grand lure to all who see its 
walls. Prosperity and grandeur seem to be the destiny of

Addendum 2, 17/11/2013: On 16/11/2013 (13 Muharram 1435), the 
300th anniversary (in Hijri years) of the fall of Isfahan to the Hotaki 
dynasty, SCP-3722 took on a notably different form. It appeared to 
emulate Isfahan following its fall in 1722, but with several notable 
alterations, such as the complete absence of SCP-3722-1. A remote 
drone was sent into Isfahan in order to ascertain the details of this 
unusual scenario.
