SCP-3665-1 is an entity that is only perceptible to the individual who 
activated SCP-3665. Exact features such as gender, age, and 
ethnicity vary based on the individual, but SCP-3665-1 is most often 
described to be a humanoid, with the addition of features similar to a 
depiction of a demon or evil spirit, such as horn-like protrusions from 
the head, bat-like wings, and a short tail. SCP-3665-1 will speak in 
the language best known by the individual who activated SCP-3665, 
and appears to have an innate knowledge of the subject's history, 
personal life, and preferences. SCP-3665-1 appears to be unaware 
of, or unwilling to acknowledge anyone except the individual who 
‘summoned' it. SCP-3665-1 is able to seemingly remember specific 
events when activated by the same person multiple times, but is 
unable or unwilling to recall events that happened when it was 
activated by another individual. 


While present, SCP-3665-1 will perform tasks that are assigned to it 
by the individual who activated SCP-3665, however, actions that 
SCP-3665-1 appears to take do not affect anything other than the 
subject's perception. For instance, if asked to move a cup from one 
table to another, the subject would visualize SCP-3665-1 moving the 
cup. No-one other than the subject would see the cup moving. 
However, when SCP-3665-1 expires, the cup would be in its original 
position. SCP-3665-1 is also seemingly unable to cause anyone 
serious injury, or do anything that would significantly affect the 
surrounding area, due to its only being able to affect the subject's 
perception. If asked to do something it is unable to, SCP-3665-1 will 
respond with: 'Leave these frivolous demands, which strike a terror 
to my fainting soul!'3. SCP-3665-1 will react similarly if asked a 
question the subject is unaware of the answer to. This can include 
giving incorrect information if the subject holds an untrue belief. After 
two hours, SCP-3665-1 will begin to disappear, described as 
evaporating slowly. During this time, all changes to the subject's 
perception will be reverted.

Footnotes 
1. Latin for ‘Man, fly!’. This is believed to be a reference to the play 


think represented the god himself and THAT is the real 
prize. The manifest lists all manner of gold and artifacts 
that the University would love to have, even if we don't 
hit the jackpot on this one... Still, | can't help but get 
excited about the prospect of bringing back the Inca's 
‘unholy grail’. 


All the best, 


P.S. 
Let's keep this quiet, it'd be a disaster if someone beat 
us there!

‘Doctor Faustus', as SCP-3665-1 has also referenced this play on 
occasion. The scene from ‘Doctor Faustus' in which this phrase is 
used involves the words appearing on the titular character's arm, 
warning him not to sign a contract with the demon Mephistophilis. 
2. This appears to be variable depending on what the subject 
considers a demon or evil spirit to be. One researcher who was 
raised in Eastern Asia reported SCP-3665-1 to appear as a human 
wearing an Oni mask with red skin. 

3. This is another quote from Doctor Faustus, the scene in which 
involves a demon refusing to elaborate on the nature of hell. 

4. This is a quote from Doctor Faustus, in which a demon provides 
an elusive response to one of the titular character's scientific 
questions. The Latin translation is 'Unequal motion with respect to 
the whole thing’. Dr. Reynard had not read Doctor Faustus at the 
time. 

5. Also a quote from Doctor Faustus, the scene from which involves 
the demon Mephistophilis explaining why Lucifer tempts humans. 
The Latin translation is 'to the unhappy, it is a comfort to have had 
company in misery’, or more simply, 'misery loves company’.

Item #: SCP-3666 
Object Class: Euclid 


Special Containment Procedures: Each individual 
affected by SCP-3666 is to be confined within a standard 
humanoid cell. Several researchers are to study the 
immune system and DNA of affected individuals to 
further understanding of SCP-3666. Doctors are to 
analyze affected immune systems for potential health 
risks and damage. 


Alternative amnestic treatments are to be utilized 
Research is to be conducted to find or create new 
medicine with the capacity to alter memories. 


Description: SCP-3666 is an allergic inflammatory 
reaction to the presence of amnestic proteins and 


substances within the bloodstream of affected 
individuals. Immune systems modified by SCP-3666 are 
unable to change or adapt to both normal anti-allergy 
treatments and those developed by the Foundation. As 
of now, no gene or allele has been correlated to the 
creation of SCP-3666 within the genome of affected 
individuals. 


Currently, 147 individuals from Scandinavian origin have 
been diagnosed with SCP-3666. This corresponds to the 
total population of the former town of Ahni, Norway. The 
town did not exhibit any anomalous properties which 
could lead to the activation of SCP-3666 within 
unaffected or affected individuals. Since the arrival of 
Foundation forces, the town has been shut down. 


Individuals affected by SCP-3666 show regular 
symptoms of digestion or skin related allergies when 
exposed to Class-B to Class-F amnestics which are 
ingested or inserted into the patient. Individuals affected 
by SCP-3666 show symptoms of respiratory related 
allergies to Class-A amnestics which are inhaled. 


Affected immune systems effectively eliminate all 
amnestic substances while inside or before they can 
reach blood vessels within the brain. Due to this effect, 
all affected individuals are effectively impervious to the 
main effects and side-effects of all amnestic treatments. 
SCP-3666 is capable of adapting itself to protect the 
central nervous system from memetics and 
cognitohazards which target regions of the brain 
processing long-term and short-term memory. 


Discovery Log: SCP-3666 was discovered following 
Incident- -O near Ahni, Norway. Foundation forces 
were quick to administer Class-A amnestics to residents 
exposed to the incident. Exposed residents did not forget 
the incident following the administration. All residents 
were found to possess the same SCP-3666 properties 
and were relocated to Site-52 for further examination. 


Item #: SCP-3666 
Object Class: Keter 


Special Containment Procedures: All border exits from 
and entrances to Norway are to be closed immediately. 
All Norwegian airlines are to be dissolved. 


All phone lines, social media, and internet connections 
from and to Norway are to be cut off. A disinformation 
campaign led by the Foundation is to create and spread 
rumors of a lethal virulent pathogen in Norway on social 
media, television networks, and radio stations. All 
information found contradicting the campaign is to be 
removed. 


All Foundation personnel stationed at Site-52 or who 
have come into contact with individuals affected by 
SCP-3666 are to remain in Norway. All personnel who 
have travelled to other countries after being stationed at 
Site-52 are to be traced and located and are to remain in 
their respective countries. These countries are to be 
locked down in a manner similar to that of Norway. 


Foundation resources are to be invested or redirected to 
research into vaccines or cures for SCP-3666 infection. 
When or if a vaccine is found, the population of all non- 
lockdown countries is to be vaccinated. When or if a cure 
is found, the population of all lockdown countries is to be 
cured before SCP-3666 is capable of contaminating non- 
lockdown countries. 


Foundation sites, areas, anomalies, and personnel which 
have not come into contact with SCP-3666 and are 
within lockdown countries are to be relocated to non- 
lockdown countries through Foundation forces. 
Foundation sites and areas which have come into 
contact with SCP-3666 are to become "independent" 
while receiving funding from the Foundation. 
"Independent" sites and areas are to never come into 
contact with non-lockdown countries or non-independent 


sites and areas. 


The Foundation is to search for alternatives to standard 

amnestics and memory altering products. All information 
concerning SCP-3666 is restricted to Level 4 Clearance 
personnel and above. The disinformation campaign led 

by the Foundation is to also apply to Level 3 Clearance 

personnel and under. 


Description: SCP-3666 is an allergic inflammatory

amnestic substances while inside or before they can 
reach blood vessels within the brain. Due to this effect, 
all affected individuals are effectively impervious to the 
main effects and side-effects of all amnestic treatments. 
SCP-3666 is capable of adapting and modifying the 
central nervous system to protect it from memetics and 
cognitohazards which target regions of the brain 
processing long-term and short-term memory. Alternative 
amnestics and memory altering products are completely 
ineffective at suppressing SCP-3666 in affected 
individuals. 


SCP-3666 is capable of spreading from person to person 
through unknown means. Due to its rapid spread, the 


cause of SCP-3666 is hypothesized to be a virus or a 
meme. The virus or the meme would be unable to be 
detected by the host's immune system and would be 
successful at perturbing it to create the effects of 
SCP-3666. As of 04/09/2019, SCP-3666 contaminates 
the entire population of Norway. 


Item #: SCP-3666 
Object Class: Keter 


Special Containment Procedures: All countries are to 
integrate Procedure-065-Abschirmung. Procedure-065- 
Abschirmung ensures: 


* The removal of all border exits and entrances from 
and to other countries. 


¢ The independence of all autonomous regions. 


* The removal of all international communication 
lines. This includes all social media, phone 
connections, radio stations, e-mails, mail and 
television networks. All countries are to have 
information, social, and communication networks 
isolated from other countries. 


¢ Monthly analyzation of citizens by Foundation 
forces to detect the presence of SCP-3666. 


The relocation of unaffected sites, personnel, 
anomalies and areas from countries affected by 
SCP-3666 to unaffected countries. 


¢ Worldwide effort to suppress and negate the 
effects of SCP-3666. 


¢ The autonomy of all sites and areas affected by 
SCP-3666. Contact with affected sites and areas is 
to be cut off. Affected sites and areas are to still 
receive funding from the Foundation. 


Information concerning SCP-3666 is restricted to Level 4 
Clearance personnel and above. All analyzation of 
individuals affected is to be automatic and never manual. 
Personnel are to always stay 50 meters away from 
affected individuals.
