SCP-1669: Self-Terminating Loop 


Item #: SCP-1669 
Object Class: Euclid 


Special Containment Procedures: SCP-1669 is housed in a 
standard humanoid containment cell at Humanoid Containment 
Site-06-3. As a former Foundation researcher, SCP-1669 is 
considered a low-risk humanoid SCP and may request items or 
materials at the discretion of Level 3 Security Staff so long as such 
materials do not violate any security protocols. 


SCP-1669 is aware of its classification as a Euclid-class anomalous 
entity but is not aware of the specifics of its containment, nor of the 
nature of 1669-Alpha events. Disclosure of this information to 
SCP-1669 is punishable by immediate transfer and/or termination; in 
the event of such disclosure, SCP-1669 is to be administered a 
Class A amnestic. All deceased instances of SCP-1669 are to be 
stored in separate cryogenic freezers following examination and 
autopsy. 


Until such time that a better understanding of 1669-Alpha events is 
made, all experimentation regarding and attempts to prevent such 
Events are indefinitely suspended. 


Description: SCP-1669 are instances of human subjects matching 
the description of Dr. Daniel Isaac, an Israeli biologist and Level 2 
Assistant Researcher and laboratory technician formerly employed 
by the Foundation at Humanoid Containment Site-06-3 until his 
classification as a Euclid-class entity on / / . Due to SCP-1669's 
status as a former Foundation employee and the nature of its 
anomalous properties, SCP-1669 is mostly cooperative with 
Foundation personnel as long as full disclosure of its anomalous 
properties and Event 1669-Alpha is not made. 


Event 1669-Alpha is an anomalous event that first occurred on / / 


and has re-occurred approximately every one hundred and sixty one 
(161) days since, with a margin of error of approximately thirty-three 
(33) hours. During a 1669-Alpha Event, a perfect copy of SCP-1669 
will soontaneously come into existence somewhere within 30 meters 
of SCP-1669 and immediately attempt to kill SCP-1669 by any 
means possible. The newer instance of SCP-1669 will not respond 
to any attempts at communication and exhibits extraordinary single- 
mindedness in the completion of its goal; it will attempt to limit 
collateral damage — especially injury or loss of life — but will not 
stop until the previous instance of SCP-1669 is dead. To date, no 
attempt to prevent the death of the previous instance of SCP-1669 
has succeeded; new instances of SCP-1669 have exhibited unusual 
strength, speed, and reflexes as well as the capability to shrug off or 
ignore pain and injury. See Addendum 1669-01 for more 
information. 


Upon the death of the previous SCP-1669 instance, SCP-1669 will 
lose consciousness for a period of no less than three (3) minutes, 
and upon returning to consciousness will have no recollection of any 
event prior to the initiation of Event 1669-Alpha. Examination and 
autopsy of SCP-1669 instances has yielded that they are exact 
copies aside from whatever clothing or equipment they are wearing 
or carrying at the time, down to the presence of birthmarks, minor 
injuries, and scar tissue. 


Investigation of the work history of Dr. Isaac has not yielded any 
anomalous items or contained objects which can explain 
SCP-1669's anomalous properties; as a Level 2 laboratory 
technician, Dr. Isaac did not have any direct contact with objects in 
containment. 


Addendum 1669-01: Log of Notable Event 1669-Alpha Iterations 


Iteration #: 1 
Date: / / 
Time: 15:21L 
Description: During a brief conversation with coworker Dr. 

outside of Biological Laboratory 3, SCP-1669-1 appeared 
from a nearby hallway, walked up behind Dr. Isaac, and stabbed him 
thirteen (13) times in the torso with a scalpel. Dr. Isaac died within 
approximately twenty-three (23) seconds, upon which SCP-1669-1 


lost consciousness. 

Note: All clothing and carried items on SCP-1669-1 were identical to 
that of Dr. Isaac, including the serial number and wear pattern ona 
twenty-dollar (USD$20) note Dr. Isaac had received as the result of 
a bet with a coworker approximately fourteen (14) minutes before 
the event. 


Iteration #: 2 

Date: // 

Time: 11:08L 

Description: SCP-1669-2 appeared out of a large air vent near 
SCP-1669-1, who had been transferred into a low-security cell 
following one hundred and sixty two (162) days of observation. 
SCP-1669-2 entered the cell and strangled SCP-1669-1 before 
security guards were able to respond, upon which SCP-1669-2 lost 
consciousness. Examination of the HVAC system showed no 
possible way in which an adult human could have gained access to 
the containment wing. 

Note: All clothing and carried items were identical, except that the 
jumpsuit worn by SCP-1669-2 was yellow instead of the regular 
orange. 


Iteration #: 8 

Date: // 

Time: 09:17L 

Description: With prior approval from the Site Director, SCP-1669-7 
was informed of the nature of Event 1669-Alpha and given body 
armor and a non-lethal firearm prior to the event. Response team 
members armed with additional non-lethal weapons were assigned 
to guard SCP-1669-7 with orders to attempt to subdue and take 
SCP-1669-8 alive if possible. SCP-1669-8 appeared during a shift 
change for the response team; during the confusion, SCP-1669-8 
managed to subdue three (3) armed personnel in hand to hand 
combat before reaching SCP-1669-7 and shooting it twice in the 
head with a high-caliber handgun. The non-lethal weapons 
employed by response team personnel appeared to have no effect. 
Note: SCP-1669 exhibited advanced training in hand-to-hand 
combat techniques in this iteration, which is inconsistent with the 
level of defensive capability known to be in SCP-1669's possession 
outside of a 1669-Alpha event. This iteration is also notable as the 


first iteration in which a new instance of SCP-1669 appeared with a 
weapon or equipment not in the possession of the previous 
instance. 


Iteration #: 12 
Date: // 
Time: 23:22L 
Description: Prior to Event 1669-Alpha, SCP-1669-11 was locked 
inside an armored personnel carrier crewed and guarded by two 
heavily armed squads from Mobile Task Force [REDACTED]. MTF - 
was given discretionary permission to protect SCP-1669-11 using 
any means at their disposal, up to and including the use of lethal 
force. SCP-1669-12 appeared wearing heavy body armor and 
wielding a man-portable high-explosive anti-tank (HEAT) rocket 
launcher, which it used to destroy the carrier. One (1) member of 
MTF - aswell as SCP-1669-11 were killed instantly and four (4) 
more team members were wounded in the attack. SCP-1669-12 was 
also injured by its proximity to the blast. 
Note: Injuries sustained by SCP-1669-12 in the explosion included a 
severed left pinky finger caused by shrapnel from the explosion. 
This finger was unable to be reattached, and all subsequent 
instances of SCP-1669 have exhibited the same missing digit. 
Tracking the serial number on the weapon used in the attack turned 
up an identical weapon that had been transferred to the armory of 
Site- , over 650km away, just two hours prior to the event. Further 
attempts to prevent Event 1669-Alpha were suspended following 
this incident.

SCP-1670: Interdimensional House of Pancakes 


Item #: SCP-1670 
Object Class: Euclid 


Special Containment Procedures: SCP-1670 is maintained by 
Foundation agents as a licensed franchise of , LLC. Research 
staff are to maintain cover in service positions during operating 
hours, while security personnel assigned to Task Force Gamma-5 
"Waffle Irons" are to maintain cover as regular customers or wait in 
the Ready Room established within the food storage area. 


Foundation personnel are allowed to provide unsatisfactory service 
for the purpose of discouraging local business. All issues relevant to 
the normal day to day operation of the site are to be forwarded to 
Corporate Liaison Robert Gooden; failure to adhere to this policy will 
result in disciplinary action. 


During SCP-1670 events research staff are to distribute amnestics 
and sedatives in the guise of complimentary beverages or food 
items while security personnel attempt to isolate the individuals 
involved in the event for observation. If affected individuals are 
determined to be non-anomalous they may be released to the public 
after a quarantine period of no less than two weeks. Anomalous 
individuals or individuals who otherwise cannot be released must be 
disposed of on site along with their possessions. Foundation 
personnel are not exempt from these procedures. 


Description: SCP-1670 is a temporal and spatial anomaly affecting 
the restaurant located at [REDACTED]. It came into 
Foundation custody in / / after spontaneously re-opening from 
three separate attempts to abandon and close the location. The 
property was seized using local eminent domain law and eventually 
re-opened in the guise of a normal franchise after all previous 
containment and demolition attempts failed. 


Unless the area surrounding SCP-1670 is maintained as a 
restaurant under the brand it will spontaneously revert to 
such, even when under direct observation. Matter displaced by this 
process has not been recovered. Spontaneous reversions to the 
state of an open restaurant also include customers and wait staff 
appearing in the act of serving and eating food. The majority of 
individuals present after such a reversion have been ordinary 
members of the local populace who claim to have arrived there 
normally or to have been continuously employed there despite the 
previous state of the location. 


These reversions to the state of an open restaurant appear to have 
been contained by simply keeping the restaurant open with 
Foundation personnel as the staff. While there are still spatial 
anomalies present at the location the local populace no longer 
appears at the location by extra-ordinary means, and a pattern of 
poor service keeps most locals away. The majority of customers are 
now travelers passing by on the nearby highway. 


SCP-1670 events are signaled by electrical anomalies and a strong 
feeling of paranoia and apprehension among those present along 
with minor relocation of objects within the location. Anomalous 
individuals may appear during these events; these individuals may 
be duplicates of others who are already extant elsewhere, often 
within the restaurant itself. These individuals can be isolated by 
careful observation although a medical examination may be 
necessary to determine their origin. 


Anomalous individuals must not be allowed to leave the location of 
SCP-1670 as their existence poses a threat to public safety. 
Security personnel must locate any duplicate or otherwise 
anomalous individuals and detain them for observation until it can be 
positively established whether they are native to our reality and can 
be safely released from custody. 


Addendum: While there are rarely visible differences between 
anomalous and ordinary individuals, postmortem investigation 
typically finds severe internal abnormalities and toxic substances, 
including but not limited to: 


¢ Extra or missing internal organs 


¢ External sensory organs located within the body 
* Orifices filled with toxic or reactive gases 

¢ Broken glass filling the stomach or lungs 

* Human remains in the stomach 

¢ Unknown symbiotic life-forms 


Notably, anomalous individuals have not yet carried any unknown or 
virulent pathogens but personnel are advised to continue observing 
proper decontamination procedures. The possessions of anomalous 
individuals should not be retained for further study as per Extra 
Dimensional Protocol 53 regarding conservation of mass and 
energy. All extra dimensional matter must be disposed of on site.

SCP-1671: Corpse Mine 


Item #: SCP-1671 
Object Class: Euclid 


Special Containment Procedures: The security perimeter of the 
property containing SCP-1671 is to be monitored by armed patrol 
and night-vision security cameras. Foundation personnel are not 
permitted within SCP-1671 without Level A hazardous material suits. 
All materials recovered from within SCP-1671 are to be sterilized 
before removal. Any personnel showing signs of sickness after entry 
to SCP-1671 are to be quarantined immediately. 


SCP-1671-2 work cycles are not to be interrupted: all direct study of 
SCP-1671-2 specimens is to be carried out upon specimens on rest 
cycle: this consists of interviews, physical examinations. Work cycle 
observation is to be carried out by remotely-operated vehicle only. 


/ /2011: Physical contact with SCP-1671-2 specimens is not 
permitted. 


/ /2013: Injured or deceased SCP-1671-2 specimens are not to be 
disturbed in any way. 


For further information on the use of recovered SCP-1671-1 
material, please see document 1671-EXP. 


Description: SCP-1671 is an abandoned coal mine located near 
[REDACTED] Pennsylvania. SCP-1671 was originally founded in 
1887 by the [REDACTED] Company, and remained in operation 
until 1923. No reports of anomalous activity have been recovered 
from the period of operation. No surface buildings from the original 
mine remain. A guard station has been constructed over the 
entrance for the storage of research materials and housing of 
security personnel and the elevator to the mine has been replaced. 
The room surrounding the primary shaft entrance has been 


expanded to contain SCP-1671-A and a barracks room. The 
temperature within SCP-1671 is a constant 35.5° C. 


SCP-1671-A is a hemisphere of cast iron, measuring 4.5 meters in 
diameter and 2.25 meters in height, located in the entry chamber of 
SCP-1671. Four 1.5 by 1.5 m hatches are located at 90 degree 
intervals on SCP-1671-A. 


The lower levels of SCP-1671 contain seams of human corpses, 
designated SCP-1671-1. SCP-1671-1 specimens are of varied age 
and race, with no apparent pattern to these traits. SCP-1671-1 
specimens are generally in a state of advanced decay due to the 
conditions within SCP-1671. Genetic testing has not matched any 
SCP-1671-1 specimens with known individuals living or dead. The 
total amount of SCP-1671-1 within SCP-1671 is unknown: seams do 
not appear to decrease in size. That is, wnen SCP-1671-1 material 
is removed, further instances of SCP-1671-1 are pushed to the front 
of the seam.
