SCP-2140 "Retroconverter" Object Class: Thaumiel
Item #: SCP-2140
Object Class: Thaumiel (SCP-2140-1-D is considered Neutralized)
Special Containment Procedures: SCP-2140 poses no threat to Foundation personnel.
Deployment to counter hostile SCP-2140-1 instances under the conditions of Appendix A is authorized.
Expanded deployment against other threats must be approved on a case-by-case basis by
O5 command and the Ethics Committee.
Every possible effort should be made to prevent creation or discovery of additional instances.
Any person exposed to, or possessing significant knowledge (as defined in Appendix C) of any
SCP-2140-1 instance is to be terminated, amnesticized or exposed to SCP-2140 at the discretion of
the Strategic Threats Officer.
The fragments of the only known copy of SCP-2140-1-D are permanently sealed in secure deep storage
at the facilities listed in Appendix E.
Description: SCP-2140 is an image derived through Project Kallinikos from SCP-2140-1-D.
SCP-2140-1 instances are alternative versions of the image.
All instances depict glyphs in the [REDACTED] script.
While it is possible for persons of any background to view isolated portions, 100% of persons
who view a complete SCP-2140 (regardless of medium) are loyal Foundation personnel with
2/2140 clearance or higher.
These persons invariably have highly corroborated personal histories (with multiple eyewitnesses,
known Foundation colleagues, and documentation) consistent with this profile.
The presence of corroborating physical evidence supports the hypothesis that this is a retroactive
alteration to personal history such that the person will always have been a loyal Foundation
employee with appropriate clearance.
It is suspected that this anomaly follows a "path of least resistance" and alters the
minimum necessary number of events (Appendix B).
No record exists of any experimental test subjects (such as D-Class personnel) or any
other person lacking appropriate background and clearance viewing the complete image.
SCP-2140-1-D was first located at the [REDACTED] dig site ███ km west of [REDACTED],
Uzbekistan.
Irregularities in the dig team's reports were noted and due to the nature of the dig site,
a memetic hazard was suspected.
MTF Eta-10 ("See No Evil") was deployed and faced heavy resistance from the dig team.
The researchers and security personnel were later discovered to have been a covert cell
within the Foundation dedicated to the retrocreation of [REDACTED] and were killed resisting capture.1
Following recovery, Project Kallinikos was enacted.
The project's separate teams analyzed sections of SCP-2140-1-D in isolation.
Their findings were given to the compartmentalized implementation team which was then able to
produce a working prototype of SCP-2140 with zero exposure to the original.
All members of the project (including all personnel exposed to early prototypes) were
subsequently exposed to SCP-2140 and amnesticized.
