SCP = "Secure, Contain, Protect" or "Special Containment Procedures". The SCP foundation is a "secret" organization attempting to contain all anomalous objects and entities. SCPs are divided into 3 main classes.
Safe = An object that does not pose a threat and are
easy and secure to contain.
Euclid = An object that poses a threat or has more complicated or
difficult containment procedures.
Keter = An object that poses a great threat or/and have very difficult and unreliable containment procedures.
The SCP foundation has dozens of
Safe facilities and thousands of SCPs in containment.
Safe: SCP-1499 is a Soviet GP-
5 gas mask. The anomalous effects of SCP-1499 activate when a
human places SCP-1499 on their head. Approximately one second after SCP-1499 is fully secured on the subject's head, the subject vanishes from view, and is no longer detectable. Upon wearing SCP-1499, test subjects report completely different surroundings than they were in prior to wearing SCP-1499. Subjects have reported that it appears barren and inhospitable, with tall
black towers filling the area. Subjects have also sighted entities in this landscape. These entities, designated SCP-1499-1, have been described as tall, nude humanoids with dark
skin. Upon removing SCP-1499 from their head, subjects reappear in the same location they were in when they put it on.
Euclid: SCP-173 is constructed from concrete and rebar with traces of Krylon brand spray
paint. The object cannot move while within a direct line of sight. Object is reported to attack by snapping the neck at the base of the skull, or by strangulation
Keter: SCP-217 is a
virus, incurable by current means, with a rate of infectivity at 100%. The progress of the infection is very
slow, with some subjects going several years before manifesting any symptoms. SCP-217 alters the biochemistry of
organic tissue, causing
organic matter to re-arrange into a form of “organic
metal”. A subject will begin to turn into a complex arrangement of gears and clockwork, these taking over for the former biological functions.
