The SCP Foundation utilizes a structured system of object classes to categorize anomalous items based on their controllability and potential threat level. This framework allows researchers and field agents to quickly assess the resources required to secure an item. Understanding these classifications is essential for anyone involved in the documentation or containment of paranormal phenomena. The standard designations range from Safe to Apollyon, each representing a distinct level of risk and operational difficulty.
Understanding the Standard Classes
The primary classification system divides anomalies into three main tiers: Safe, Euclid, and Keter. These categories reflect not only the inherent danger of the object but also the likelihood of successful containment. The Foundation allocates significant resources to maintain these barriers, ensuring that reality remains stable despite the existence of these anomalies. Misclassification can lead to catastrophic breaches, making the accuracy of these labels a top priority for O5 Command.
Safe Class Objects
An object is designated Safe when containment procedures are straightforward and reliable. These anomalies typically require minimal maintenance and pose little risk to personnel under normal conditions. Examples include items that are inert, easily locked away, or possess effects that are easily neutralized. While generally manageable, a Safe object can still be dangerous if handled improperly, necessitating strict adherence to protocol regardless of the class designation.
Euclid Class Objects
Euclid-class anomalies are the most unpredictable category, often requiring complex or experimental procedures to contain. These objects may exhibit unpredictable behavior, difficult-to-duplicate properties, or incomplete data regarding their origins. Many reality-bending entities fall into this classification due to the sheer complexity of understanding and managing their effects. Research into Euclid objects is constant, as new information can shift their containment strategy entirely.
Keter Class Objects
Keter-class objects are those which are currently impossible or highly impractical to contain with existing resources and technology. These anomalies actively resist containment or require an excessive expenditure of effort to suppress. The designation does not imply an object is more dangerous, but rather that the Foundation lacks the means to secure it effectively. Many Keter items are kept under observation or managed through mobile task forces rather than fixed containment facilities.
Specialized and Esoteric Classes
Beyond the standard tiers, the Foundation employs a series of specialized classes for specific logistical and metaphysical scenarios. These designations address the nature of the threat beyond simple physical danger, accounting for temporal, informational, and existential risks. They are used less frequently but are critical for the oversight of the most unusual anomalies.
Thaumiel Class Objects
Thaumiel-class items are the rarest and most strategically valuable assets of the Foundation. These anomalies are used to contain or neutralize other Keter-class threats. Because they are essential for the stability of the organization, their existence is highly classified, known only to Level 4 personnel. The deployment of a Thaumiel object is a last resort, often involving significant sacrifice.
Neutralized and Explained Objects
An anomaly may lose its designation once it is no longer active or its properties are fully understood and replicated. Neutralized objects are those that have been destroyed or rendered harmless, while Explained objects are those whose effects are now understood to be non-anomalous, such as a psychological hallucination or a natural chemical compound. These items are removed from the active catalog, though historical records remain accessible for research purposes.
High-Threat Classifications
For scenarios involving existential risks to humanity or reality itself, the Foundation utilizes a separate tier of classifications. These objects are not necessarily more powerful but represent threats that could end the human race or the fabric of the universe. Access to information regarding these classes is strictly limited to prevent panic and ensure only the highest levels of command are aware of the true scope of the anomalous world.
