The SCP Foundation utilizes a standardized system of scp danger levels to categorize anomalies based on the potential threat they pose to personnel, the public, and global stability. This classification is not merely a formality but a critical component of operational security, dictating the resources allocated, the procedures employed, and the immediacy of the response required. Understanding these tiers is essential for anyone interacting with the anomalous, as it provides a framework for evaluating risk beyond the simple presence of hostile behavior.
Understanding the Standard Spectrum
At the core of the classification system are the baseline designations: Safe, Euclid, and Keter. These categories describe the ease of containment rather than the severity of the anomaly's effects. A Safe designation implies that the object can be securely stored and handled with predictable protocols, often requiring minimal resources for long-term stability. Conversely, a Keter label signifies that current containment methods have failed or are insufficient, indicating an entity that actively breaches regulations or requires an impractical level of oversight to prevent catastrophic outcomes.
Safe Class Anomalies
Safe class objects are those that are easily and reliably contained with standard procedures. They typically exhibit predictable behavior and pose minimal risk when handled correctly. Examples include items with straightforward activation mechanisms that can be neutralized with simple countermeasures or entities that are non-sapient and physically limited. While labeled Safe, complacency is discouraged, as unexpected variables can sometimes elevate the risk of even the most stable anomalies.
Euclid Class Considerations
Euclid anomalies represent the bulk of documented SCPs and are often the most challenging to manage due to their unpredictable nature. These entities may require complex containment procedures, exhibit poorly understood abilities, or interact with the environment in erratic ways. The Euclid classification is a catch-all for anomalies that do not fit neatly into the Safe or Keter categories, acknowledging that while containment is currently achievable, it demands constant vigilance, specialized expertise, and robust redundancy in protocol design.
High-Threat Classifications
Above the standard spectrum lie the high-end designations reserved for realities-bending threats that could destabilize the entire foundation. These anomalies are not just dangerous; they are existential risks that require immediate and extraordinary intervention. The criteria for these classifications are strict, focusing on the scale of potential damage rather than just the likelihood of breach.
Keter and Beyond
A Keter anomaly is one that cannot be contained by the Foundation through normal means. This may be due to the entity's reality-warping abilities, its capacity to manipulate followers to facilitate escape, or a fundamental resistance to current technology. The goal for Keter-class objects is not necessarily secure containment, but effective suppression and risk mitigation to prevent large-scale casualties or cognitive hazards.
Apollyon and Narrative Threats
Reserved for the most severe scenarios, the Apollyon designation is applied to anomalies that are actively or predictably leading to the end of the world or the collapse of the multiverse. These are entities or events that the Foundation acknowledges it cannot stop, only potentially delay or influence. Closely related are the Daevite and Sarkic threat vectors, which are evaluated based on the historical and supernatural magnitude of the cults and forces they represent, posing risks that span centuries or millennia.
Dynamic Assessment and Special Classes
The danger levels are not static; they are subject to review as new information becomes available or as the anomaly evolves. A project may be downgraded from Euclid to Safe if a reliable containment method is discovered, or upgraded to Keter if it demonstrates unforeseen aggression. Furthermore, special classifications such as Thaumiel, Explained, and Neutralized serve specific administrative purposes, distinguishing objects that are used to contain other anomalies, those that are hoaxes or naturally explained phenomena, and those that have been successfully rendered inert, respectively.
