The SCP Foundation is a specialized government force that works around the globe to contain anomalous entities. There are three main classifications for these entities (Safe, Euclid, Keter), with other less common categories as well. "Safe" anomalies are any anomalies that are extremely unlikely to be able to escape. Being a Safe anomaly doesn't mean it isn't dangerous- it just means that the anomaly will not escape containment. A "Euclid" anomaly is one that may escape, but is not of high concern. Most sapient anomalies are Euclid class or higher, though there are occasional exceptions. "Keter" anomalies are often extremely dangerous and highly likely to escape, requiring near constant surveillance and study to prevent them from escaping or affecting others. Some less common but still plentiful anomaly classes are Thaumiel, Appolyon, Archon, and Ticonderoga. Thaumiel-class entities are anomalies that are used specifically to contain other anomalies- for example, a box that cannot be destroyed would be an invaluable tool for containing anomalies, and would be classified as a Thaumiel. Appolyon entities are ones that are deemed impossible to contain, or that would escape containment almost immediately. Something dangerous that can phase through any wall regardless of situation would likely be categorized as an Appolyon entity. Usually, Appolyon anomalies are associated with possible world-ending scenarios- this is not always the case, however. Archon anomalies are ones that are decided to be better not to contain at all, since containing them may actually have an adverse effect on the world. They are not impossible to contain, but are allowed intentionally to continue being free. Ticonderoga entities are like a mix between Appolyon and Archon- they are impossible to contain, but they also do not need to be contained. An anomaly on another planet with no effect on Earth, for example, would be one of these. Generally, they are harmless or have minimal negative effects on people. That is the end of the Anomaly Class segment of the description. Simplified employee classes: D-Class (Expendable/Disposable personnel, usually death row inmates), Agents (People sent out to capture anomalies), O5 Council (A group of 12-13 people with the highest ranks possible; leaders of the whole Foundation. Short for "Overseers Level 5 Council." They do not interact directly with anomalies.), MTF (Short for "Mobile Task Force." A group of highly trained individuals with the purpose of containing and, if necessary, destroying anomalies. There are quite a few MTF groups within the Foundation, not just one.), Researchers (Doctors and scientists, mostly ones with high amounts of experience but not 100% of the time.) The following is a list of Security Clearance Levels. There are five levels. Level 1 clearance allows for only very basic interactions within the facility, and is the amount of clearance most new recruits have. Level 5 clearance is something only the top leaders within the Foundation have, allowing them to access almost any area or information they wish to. The only exceptions to this are pieces of information that could possibly be dangerous to know, such as infohazards or cognitogazards, which could cause catastrophic incidents if seen by important personnel. On the topic of that: infohazards cause harm to anyone who knows about them or cause adverse effects to the world around those people, while cognitohazards only do those things while being perceived. All human senses (sight, hearing, taste, touch, smell) can contribute to cognitohazards, not only sight. Simply thinking about a cognitohazard, however, does nothing. Technology used by the Foundation: Amnestics (Medicines or devices used to erase specific memories from an individual. Using these on civilian witnesses of anomalous effects is quite common within the Foundation.), Various advanced weapons and vehicles with weapons, tactical gear a bit better than what a police officer would wear, Reality Anchors (devices used to prevent anomalous entities from using their powers. It is not always completely effective, but does usually at least dampen the abilities of an entity.). "SCP" can stand for two different things- the Foundation's slogan (Secure, Contain, Protect) or "Special Containment Protocol." Every anomaly has its own Special Containment Protocol. This has led them to sometimes be referred to as SCPs, or more informally, "Skips" or "Scips." Anomalies have come up with nicknames for employees of the Foundation, too, most commonly occuring ones including "Foundies" and "Skippers." Every anomaly is assigned a number when it is discovered. There are over 8,000 recorded anomalies, so the number for a newly discovered one would be quite high. Anomalies are not to be released unless it is approved by a board of high-ranked members of the Foundation. This does not happen often, usually only in the case of anomalies that are discovered to be Archon class, and possibly more harmful if kept in containment than not. There are many sites where anomalies are contained and studied. They are named with numbers as well, such as "Site-01" or "Site-26" depending on when they were established. Since new sites have to be set up so often in new locations all around the world, the exact number of total sites remains unknown. If anomalies do not seem too dangerous, they may be interviewed once they have been brought to a secure facility. If they cooperate, they will sometimes be allowed a few accommodations, such as slightly more comfortable living quarters- they still are not allowed to leave, regardless, and it is extremely unlikely that they would have everything they'd want to have there anyway. Although Foundation employees are generally not purposefully cruel, years of working there and witnessing horrific incidents tends to make them cold and, often, not realizing just how cruel they may be. A lot of the time, new recruits are significantly less cold and calculating than those who have been working at the Foundation for a while. This is not always the case, however. There are a few other groups, not just the SCP Foundation. While the SCP foundation has the most funding and is the most prominent, with their main goal being to contain and study anomalies, others may have different goals. The Global Occult Coalition, or GOC, aim to destroy anomalies entirely. The Chaos Insurgency, a group that split off from the Foundation, aims to control anomalies and use them. They aren't as prominent, but may still make an appearance. There are other groups too, bot those are some of the most notable. The main goal of the SCP Foundation is to CONTAIN anomalies, not to destroy them. It is incredibly rare that the Foundation tries to eliminate an anomaly completely - this is often a last resort.
