Notice to the Foundation, Multiversal Iteration 2N:
By order of Eternal President Girard Niang: Earth, Multiversal Iteration 4V, has been severed from ☽☽☽ jurisdiction and left to its own devices. Further involvement on the part of the ☽☽☽ Humanity Defense Corps would have only exacerbated the situation and led to cross-dimensional casualties.
As an additional means to ensure eternal quarantine, JALAKÅRA Himself has whispered the hymn of silent flesh into Iteration 4V. While regrettable, this action was a product of absolute necessity, and executed to protect the multi-dimensional majority of humans. Fortunately, extraterrestrial life in 4V continues to thrive.
We will now provide you with 4V's document SCP-4839,1 if only as a warning. We know your cause is just — but for your own sake, know when to stop.

You are watched. You are Protected. You are loved.

Kullervo counter specifications for SCP-4839

Item #: SCP-4839
Object Class: Keter
Threat Level: Black •
Special Containment Procedures: Due to the large volume of SCP-4839 in existence, Mass Containment Zone-4839, hereafter MCZ-4839, has been constructed within SCP-2400. MCZ-4839 is composed of two warehouses for storage of SCP-4839, living quarters for staff, and barracks for guards. Each warehouse will be equipped with a Kullervo Suppressor, thereby neutralizing the dangerous effects of contained instances.
Items that carry SCP-4839 are to be contained as-is. Living instances are to be accommodated with nutrition and other sustenance. Deceased instances are to be contained, as well.
Acquisition of additional SCP-4839 is to be carried out through the use of Kullervo Detectors, available at every major Foundation site. Any usage of Kullervo Detectors that deviates from the provided instruction manual is grounds for immediate termination of employment with the Foundation and the administration of Class-C amnestics.
Though SCP-4839 poses no threat while contained, it is estimated that only 4% of SCP-4839 in existence is currently under containment. Failure to contain at least 70% of SCP-4839 by 12/2/2065 will result in a ZK-class reality failure scenario.
Description: SCP-4839 is a subatomic particle that can only be detected with a Barton-Salas Kullervo Detector2. It is discovered SCP-4839 cannot be transferred from its host object, and does not affect the object's mass.
It is extradimensional in origin, and is believed to be the catalyst of another reality's forced assimilation of our own.3
So far, SCP-4839 has been discovered in the following objects:

Source
Acquisition Strategy
Cover Strategy

Julep-brand window-mounted air conditioners manufactured after 1986
Julep Electric seized by the Foundation and dissolved. A product recall is in effect.
Asbestos contamination.

The Bangka slow loris (Nycticebus bancanus)
All wild instances, approximately 70% previously captive specimens, and approximately 40% of deceased specimens have been captured and contained.
The species is extinct in the wild due to climate change.

The works of the Italian baroque painter, Artemisia Gentileschi
Captured in raids; owners amnesticized.
Lost in a warehouse fire.

Leaves of the Ginkgo tree (Ginkgo biloba)
Acquisition ongoing. Complete containment would prove impractical; at most, 70% of live and deceased specimens can be contained.
A virus from the Mesozoic Era that preyed upon ginkgo plants has been released from Arctic permafrost due to climate change.

More items may be added to this list, pending the discovery of SCP-4839 elsewhere.

Kullervo counter specifications for SCP-4839

As of 6/13/2028, revisions have been made to this article.
Item #: SCP-4839
Object Class: Keter
Threat Level: Black •

MCZ-4839 is composed of 27 warehouses for storage of SCP-4839, living quarters for staff, and barracks for guards. Each warehouse will be equipped with a Kullervo Suppressor, thereby neutralizing the dangerous effects of contained instances.
Items that carry SCP-4839 are to be contained as-is. Live instances are to be placed in suspended animation.
Acquisition of additional SCP-4839 is to be carried out through the use of Kullervo Detectors, available at every major Foundation site. Any usage of Kullervo Detectors that deviates from the provided instruction manual is grounds for immediate termination of employment with the Foundation and the administration of Class-C amnestics.

SCP-4839-Omega, as depicted in documents recovered from GoI-4817 “Green Sky Tavern”

Though SCP-4839 poses no threat while contained, it is estimated that only 4% of SCP-4839 in existence is currently under containment. Failure to contain at least 90% of SCP-4839 by 2185 will result in a ZK-class reality failure scenario.
Description: SCP-4839 is a subatomic particle that can only be detected with a Barton-Salas Kullervo Detector. It is discovered SCP-4839 cannot be transferred from its host object, and does not affect the object's mass.
It is extradimensional in origin, and is believed confirmed to be the catalyst for the destruction of our universe by SCP-4839-Omega — a hostile, reality-bending entity from Universe-91-Lambda. SCP-4839-Omega is also known as DREAD KÜLLERVO or the Seventh Prince of Corbenic.
So far, SCP-4839 has been discovered in 2,294 different types of objects. For a full list of acquisition and cover strategies, please refer to Document-4839-Foxtrot.

(IMAGE PENDING REVIEW)

As of 2/1/2032, this article has been reclassified.
Item #: SCP-4839
Object Class: Drygioni4
Threat Level: Black •
Special Containment Procedures: Containment procedures from the most current revision prior to audit are to remain in place, pending final review from the O7 council. Should the authenticity of SCP-4839's existence, anomalous nature, and danger to the public be determined to be false, the object class will be changed to “Explained” and SCP-4839 will be decommissioned.

AUDIT REPORT - 2/14/2032
AUDITED ITEM: SCP-4839
STAFF MEMBER(S) RESPONSIBLE: Dr. Aaron Hamlin
EVIDENCE AGAINST AUTHENTICITY
- Lack of testing records.
- Incident 99-150-B, whereupon a Junior Researcher accidentally dropped a Barton-Salas Kullervo Detector. Disassembly of the broken unit revealed no capacity to detect anomalous energy sources.
- Document-4839-Charlie: Written confession from Dr. Aaron Hamlin that the existence of GoI-4817 “Green Sky Tavern” was fabricated at the behest of an anonymous third party.
- Document 4839-Delta: — a sworn declaration from GoI-419 “Three Moons Initiative” claiming that the Seventh Prince of Corbenic (their benefactor) was unaware of any of its alleged plans outlined in SCP-4839. In addition, the entity is not named “Dread Kullervo”, and is considering extradimensional legal action against the Foundation for libel. Document was provided by an SCP-2578-D instance and stamped with lie-detecting thaumaturgical glyphs.
EVIDENCE FOR AUTHENTICITY
- Document 4839-Tango5 as provided by the Administrator.
O7 COUNCIL VOTE TO DECOMMISSION SCP-4839:
Yea: 4
Nay: 7
Abstain: 2
VOTE FAILED. SCP-4839 UPHELD.

SCP-4839

There have been changes made.
Item #: SCP-4839
Object Class: Keter-eschaton
Threat Level: Black •
Special Containment Procedures: Due to the large volume of SCP-4839 in existence, Mass Containment Zone-4839, hereafter MCZ-4839, has been constructed within SCP-2400. MCZ-4839 is composed of as many warehouses as needed for storage of SCP-4839, et cetera. Each warehouse will be equipped with a Kullervo Suppressor.
Items that carry SCP-4839 are to be put in boxes and never taken out.
Acquisition of additional SCP-4839 is to be carried out by any means necessary, and over all other Foundation priorities. In addition, due to the Administrator's crucial function in the containment of SCP-4839, he is to be kept alive by any means necessary, as an equal priority. All staff are advised that anomalous means to extend the human life have been retroactively approved by the O7 Council prior to their dissolution.

SCP-4839

Though SCP-4839 poses no threat while contained, it is estimated that only 4% of SCP-4839 in existence is currently under containment. Failure to contain at least 96% of SCP-4839 as soon as possible will result in a ZK-class reality failure scenario.
Description: SCP-4839 is a subatomic particle that can only be detected with a Barton-Salas Kullervo Detector. It is discovered SCP-4839 cannot be transferred from its host object, and does not affect the object's mass.
It is extradimensional in origin, and very dangerous. So far, SCP-4839 has been discovered in 13% of all matter on Earth, as well as every anomalous item in foundation custody.
In addition, it has been confirmed that SCP-4839 is directly responsible for the hostile military action upon the foundation by agents of the Three Moons Initiative, as well as the subsequent “Iteration 4V Dimensional Quarantine” event that has yet to be explained.

SCP-4839

Changes.
Item #: SCP-4839
Object Class: Bad
Threat Level: Really Bad
Special Containment Procedures: Keep putting it in the boxes. Then, keep it in the boxes. Don't steal. This isn't hard. Stop saying it is.

SCP-4839

Description: None needed.
Addendum - Notice from the Administrator:

Look, I know there's been a lot of changes lately. More sad people. More screaming. More people not wanting to put things in the box. More people not wanting to be in the box. More people thinking that the boxes are bad, that there are too many boxes. That I can't fit a whole planet in a box. That too many people are dying in the boxes. That we can't put a box of all boxes in a box, that's a pair of ducks or something. That there's no real reason to keep putting things in boxes. That this was all some kind of K-class scenario in itself.
It's confusing — I get that. It makes my head hurt. It takes really, really, really, really smart people to understand it. And that's where you guys come in! I love all the work you're doing. You do what I can't, because I'm not human anymore. Which is okay — just a part of give and take, right? There was a story where a guy gave his right eye to another guy for wisdom. I forget how the rest of it goes. Point being, necessary sacrifices.
You don't think I've been having problems too? There's something that makes me sad. It goes like this: see, I'm the Administrator. That means I administrate. All the things in the Foundation are here because I have them. And even then, there are people who think that I'm going too far.
Putting things in boxes is bad. I get that.
You know what's worse? Stealing.
Love,
Aaron Hamlin, Administrator of the Foundation
PS — please see this guide6 to not being sad if you're feeling sad.
