If the offending vessel dives below 4,100 metres, SCP-3924 
becomes hostile and will attack by use of incendiary torpedoes and/ 
or rising mines; SCP-3924 will become increasingly aggressive in 
tactics the longer the vessel is below the 4,100 metre threshold, the 
deeper it gets, and the more aggressive the vessel becomes in 
retaliation (if at all). SCP-3924 will continue attacking until the 
encroaching vessel either rises above 4,100 metres below surface, 
or is catastrophically destroyed; due to the fact SCP-3924’s primary 
strategy appears to be focused upon rupturing ballast tanks, the 
latter is the most common outcome. If a vessel rises above the 
4,100-metre threshold, SCP-3924 will immediately cease attacking, 
but will remain in an active state until the vessel rises above a 
“sufficient” depth. 


SCP-3924 periodically enters an active/hostile state in the absence 
of any encroaching vessels; in all such cases, SCP-3924 appears to 
broadcast, and attack, an indeterminate object/entity between it and 
the seafloor. To date, sonar has failed to detect any such objects/ 
entities. 


Addendum |: Incident 3924-A 


On January 9, 2018, SCP-3924 entered a hostile state and began 
firing munitions towards the seabed. During this time, a pre- 
prepared and unmanned submersible was deployed several 
hundred kilometres away in an attempt to reach the Hellenic Trench 
seafloor while SCP-3924 was preoccupied. 


Once the submersible passed the 4,100-metre threshold, SCP-3924 
immediately began firing torpedoes in its direction, despite showing 
no awareness of the submersible beforehand. SCP-3924 made no 
attempts to intercept the submersible, apparently prioritising the 


guys have been real nice to us- 
507-B: More than we might deserve, really. 


507-A: -But we also know that this could be a rather enticing 
opportunity for your research department. It'd probably be best if you 
didn’t know which one of us was- 


Dr. _: Temporary? 
507-A: Expendable. 


Dr. _ :... | don’t know what kind of stories you two have been 
sharing, but our job is to secure and protect the likes of you. 
Perhaps this other reality has a less benign code of conduct? 


507-B: And perhaps | can shoot fireballs from my mouth. 


507-A: We don’t mean to be hurtful, but this place isn’t the best 
source of human compassion. I’m sure that there’s at least one 
person on staff who would love breaking me open in an attempt to 
find out how all this freaky stuff works, if it wasn’t for the fact that you 
couldn’t keep studying me afterwards. 


507-B: Do you have to put it like that? | have enough things that 
keep me awake at night. 


507-A: Good god, | know. Once there was this guy with a huge ass 
smile- 


507-B: You met him too? 

507-A: Nearly soiled myself. 

507-B: | wish | was that lucky. 

Dr. _: You know, this could be interpreted as a security breach. 


507-B: Who’s the doppelganger going to report to? Alternate-SCP? 
I’m fairly sure that there’s a better chance of a meteor striking this 
place than successful cross-dimensional sabotage. 


unseen threat below it. 


After thirteen minutes, SCP-3924 ceased firing towards the seafloor 
and immediately changed course to intercept the submersible 
(which had reached a depth of 4,954 metres). SCP-3924 rapidly 
accelerated to 337 km/h, reaching the submersible within several 
minutes and destroying it — sonar observation detected portions of 
SCP-3924’s hull shedding during this maneuver. 


SCP-3924 then ascended to a depth of 4,500 metres and began 
deploying rising mines in an attempt to damage or sink ships at the 
sea’s surface; [DATA REDACTED], [DATA REDACTED] and [DATA 
REDACTED] were critically damaged and sunk. SCP-3924 
remained aggressive to surface vessels for a further three hours, 
after which it resumed normal behaviour. To date, this is the only 
time SCP-3924 has attacked vessels outside of its active zone. 


Further attempts to surpass the 4,100 metre threshold are strictly 
forbidden. 


Addendum Il: Incident 3924-B 


On April 3, 2018, SCP-3924 again entered a hostile state in 
response to an undetected threat. Unlike previous renditions, 
SCP-3924 continuously fired towards the seafloor for 334 
consecutive hours, during which it progressively descended to a 
depth of 5,250 metres. 


On April 17, SCP-3924 ceased firing and began broadcasting a 
previously unrecorded audio signature in all directions; three 
minutes later, SCP-3924 rapidly descended towards the seafloor, 
but disappeared from sonar detection immediately prior to impact. 


Attempts to locate SCP-3924 or its wreckage throughout the 
Hellenic Trench, either through sonar or visual detection, are 
currently ongoing, but are thus far inconclusive. 


SCP-3924 tentatively reclassified Uncontained/Neutralised. 
Addendum Il: Incident 3924-C 


On April 20, 2018, SCP-3924 was detected by sonar within the 


Calypso Deep region of the Hellenic Trench, approximately 75 km 
from where it disappeared. Sonar imaging shows that SCP-3924 
appears to have suffered catastrophic rupturing of most, if not all, 
ballast tanks, but is attempting to ascend under (assumed) thruster 
propulsion alone. Since reappearance, SCP-3924’s behaviour has 
drastically changed; SCP-3924 will only respond to vessels within a 
15 km radius, which it will aggressively fire upon, and SCP-3924 no 
longer produces any detectable audio. 


SCP-3924, at its current heading and speed, is estimated to return 
to its regular roaming zone by 23 March, 2019.

SCP-3925: It's All Papers and Forms 


Item #: SCP-3925 
Object Class: Keter 


Special Containment Procedures: As SCP-3925 has a global 
reach and is spontaneously generated from an unknown source, full 
containment is not currently feasible. Until such time as a permanent 
containment solution can be found, these procedures have been 
developed in order to minimise the duration and scale of SCP-3925 
events and lower the risk of public exposure. 


All individuals under the effect of an SCP-3925 event, once 
identified by local Foundation sources, are to be transported to the 
nearest Subdivision 03 facility. With the cooperation of national and 
international governments, these have been provided with the cover 
of government agencies relevant to the region. Affected individuals 
will be given an appropriate briefing regarding the agency needing to 
collect information from them, and reside on site while they complete 
SCP-3925-1 with the assistance of Foundation clerical staff. Once 
SCP-3925-1 has been completed to a satisfactory degree and the 
SCP-3925 event affecting an individual has concluded, they may 
then be released to their previous activities, with a subsequent 60- 
day observation period in the community. 


Securing the cooperation of SCP-3925 affected individuals in this 
manner has been found to be the most effective and humane way of 
SCP-3925 containment, and each Subdivision 03 facility has been 
authorised to pay these individuals a salary based on local wages 
for the duration of their time. However, coercion should be 
considered if individuals refuse to cooperate. Disclosure of classified 
Foundation data regarding the nature of SCP-3925 is authorised 
with the approval of level 4 staff, but personality types where this 
assists in securing cooperation are uncommon. If coercive 
measures were used, or individuals access classified information at 
any point in this process, amnestics should be administered prior to 


their release into the community. 


If SCP-3925-1 is impossible to successfully complete, or a 
SCP-3925 event persists for more than 20 iterations, termination of 
the affected individual is advised. After the events of Incident 
3925-1, termination of any individual under the effect of SCP-3925 is 
prohibited. As partially completing an iteration of SCP-3925-1 
reduces the growth rate of subsequent iterations, optimal 
containment requires some individuals to continue working on 
SCP-3925-1 indefinitely. Given the distress this situation causes, 
coercion is necessary for this purpose. There are currently 
individuals in this situation in Foundation custody. 


Since 1989, Administrative Subdivision 03 has been responsible for 
SCP-3925 management to facilitate centralised and streamlined 
containment measures. See Addendum 3925-1 for details. 


Description: SCP-3925 is a phenomenon where affected 
individuals receive an A4 paper form requesting varying personal 
details (SCP-3925-1). From the first receipt of SCP-3925-1 
individuals are considered to be affected by an ongoing SCP-3925 
event. If SCP-3925-1 is completed successfully and placed in a 
mailbox within 30 days, it will dematerialise and the SCP-3925 event 
will conclude. However, if SCP-3925-1 is completed incorrectly or 
not returned, the individual will receive a new iteration of 
SCP-3925-1 to which the same conditions apply. When a new 
iteration is generated, the previous iteration loses its anomalous 
properties. Efforts to track SCP-3925-1 prior to its appearance or 
after its disappearance have been unsuccessful. 


SCP-3925 is estimated to affect ~200 individuals per month 
worldwide. All affected individuals are literate and numerate adults 
who reside in areas with a developed postal system, although 
SCP-3925-1 appears to materialise at the individual's dwelling rather 
than being delivered by the postal service. However, once an 
individual is under SCP-3925's effect, these criteria no longer apply, 
and SCP-3925-1 will continue to manifest in their vicinity. Given 
these requirements, SCP-3925 has historically been observed in the 
developed world, but changing global economic circumstances have 
led to an increase in SCP-3925 events in developing nations. There 
are otherwise no distinguishing characteristics of affected 


individuals. SCP-3925-1 appears in the primary language of the 
affected individual (over 50 languages in 120 countries have been 
observed). As of 2017, 60,948 SCP-3925 events have been 
documented, with approximately 3000 events ongoing at any given 
time under Foundation surveillance and an estimated 2000 outside 
of this. 


Details requested by SCP-3925-1 are initially mundane and 
straightforward (name, age, sex etc.) and ending an event at this 
point is relatively simple. An estimated 75% of SCP-3925 events are 
completed by the general public in the 1st or 2nd iterations of 
SCP-3925-1 and do not come to Foundation attention. However, 
subsequent iterations of SCP-3925-1 increase in length! and 
complexity, progressing to more complicated information (eg. daily 
household electricity consumption) and becoming increasingly 
personal or bizarre (eg. most traumatic childhood memory). 
Formatting and design of SCP-3925-1 varies between individuals 
but remains consistent across iterations. All examples of 
SCP-3925-1 conclude with the following text. 


Thank you for your assistance. 
Property of Central Records, [current year] 


Examples of iterations of SCP-3925-1 are shown below. 


Any individual can fill out SCP-3925-1, but due to the frequently 
personal nature of the questions the primary subject's input is 
required to complete it accurately. All information requested by 
SCP-3925-1 is theoretically available to the affected individual, but 
more complex questions can be practically impossible to complete 
due to either the effort or memory recall required to collect the 
relevant information. As SCP-3925-1 iterations also increase in size, 
iterations beyond the 40th iteration are essentially impossible to 
complete. Partial completion of SCP-3925-1 reduces the growth of 
subsequent iterations, but as this property is relative to the 
percentage of SCP-3925-1 correctly completed, it is estimated that 


an SCP-3925 event beyond the 60th iteration (numbering between 
40,000 and 60,000 pages, assuming uncontrolled growth of 
SCP-3925-1 prior to this) would be impossible to complete to a 
degree necessary to inhibit future SCP-3925-1 growth. This would 
result in an eventual NK-class end-of-the-world scenario, with the 
mass of SCP-3925-1 predicted to exceed the mass of the Earth by 
the 350th iteration. Due to this property, both early detection and 
timely completion are a high priority for the Foundation. 


The death of affected individuals was initially thought sufficient to 
end an SCP-3925 event, and termination was authorised for when 
completion of SCP-3925-1 was infeasible. This practice was halted 
after Incident 3925-1 and current procedures implemented. Death of 
the affected individual by natural causes still appears to end 
SCP-3925 events. 


Incident 3925-1: On 02/01/1986, Foundation sources in the French 
government were alerted to an ongoing SCP-3925 event after a 
social welfare investigation of the Lyon residence of one M. Leblanc, 
known as a local eccentric and stereotypical 'hoarder'. His residence 
was found to be filled with inert SCP-3925-1, with the active 
SCP-3925-1 numbering 22,522 pages, estimated to be the 55th 
iteration. AS conventional completion of the SCP-3925 event was 
unlikely, particularly given the individual's mental state, termination 
was advised and the order was authorised by Dr Becker, then Site 
deputy director. M. Leblanc was terminated by Foundation agents 
on 09/01/1986. 


On 01/02/1986, an SCP-3925-1 iteration numbering 30,092 pages 
materialised in the Site mailroom. The content was specific to Dr 
Becker, but addressed him as "the party with administrative 
responsibility for M. Leblanc". When he was informed of this 
development, Dr Becker attempted to jump from his office window, 
but was restrained by his colleagues. After psychological 
intervention, he was reassigned to full-time work on SCP-3925-1 
and is currently based at Administrative Subdivision 03's Europe 
Offices. 


Addendum 3925-1: Administrative Subdivision 03 


Administrative Subdivision 03 (‘Service for Clerical Processing’) was 


established in 1989 in order to manage the increasing demands on 
Foundation staff related to SCP-3925 events. Its primary function is 
to accommodate individuals affected by SCP-3925 and assist them 
with completion of SCP-3925-1 with the assistance of Foundation 
clerical staff. It also holds responsibility for research relating to 
SCP-3925. 


There are currently 4 major regional centres, selected to cover 
populated areas with high rates of SCP-3925 events. Each centre 
has a cover agency (in brackets) arranged in collaboration with 
government authorities, chosen as an authority that might plausibly 
require the information requested in SCP-3925-1. 


¢ USA/North America, New York, headquarters (US Internal 
Revenue Service) 

¢ Europe West, Brussels (European Commission, Records 
Department?) 

¢ Europe East/CIS, Moscow (Russian Federation Federal 
Security Service) 

* China, Beijing (Ministry of Public Security) 


The O5 Council has approved the development of India and Middle 
East/North Africa centres, planned for opening by 2025. 


Subdivision 03 currently employs [REDACTED] Foundation staff, 
under the supervision of Director Y. L. Liu. As the bulk of its work is 
conducted in the guise of normal governmental functions, without 
visible anomalous activity, it has employed non-Foundation civilians 
since 1993 in many non-essential roles. These personnel are 
considered Foundation sub-contractors with Level 0 security 
clearance. There are 21,400 sub-contractors on the Subdivision 03 
payroll as of 2015.
