Item #: SCP-XXXX

Object Class: Safe

Special Containment procedures: A copy of each known instance of SCP-XXXX-2 is to be maintained in a containment locker in Room 22 of the Passive Containment Wing of Site-73.

Researchers with clearance level 2 or higher may request a SCP-XXXX-2 copy for experimentation; any piece of written media compatible with the SCP-XXXX-2 instance is to be placed directly over it for a period of five days, making sure to maximize the contact area between both documents. Other than these copies, researchers are not allowed to take any material derived from paper-pulp, into or from Room 22, regardless of whether they access a SCP-XXXX-2 copy or not.

Instances of SCP-XXXX-2 found outside of Foundation custody are to be brought to Site-73, analyzed and classified; if they belong to a previously-unknown SCP-XXXX-2 ecosystem, it is to be kept per the procedures described above; otherwise they are to be incinerated.

Description: SCP-XXXX are a collection of two-dimensional automata1 found in text written on paper2. Most of these closely resemble characters such as punctuation marks or letters. SCP-XXXX instances rely on characters present in the text, as well as on each other, to survive, using preexisting characters as a food source or as shelter. Studies on the effect of SCP-XXXX on ink have been inconclusive; ink seems to still be present in the areas that have been "eaten away" by SCP-XXXX, but the wavelenghts they absorb and reflect are modified through a poorly-understood process. The anomalous behavior of ink compounds present in documents infested with SCP-XXXX is useful to identify previously-contaminated materials, even if they appear to be non-anomalous under normal circumstances.

SCP-XXXX may transfer to a document or page that is in direct contact with one currently infested. SCP-XXXX instances prefer to move into documents with similar written and chemical composition: books affected by the phenomenon have an average of 93% of their pages contaminated after a period of 5 days; in comparison, contamination of blank paper has a success rate of under 10%, and contamination of cardboard, under 1%. SCP-XXXX is unable to transfer to digital media, materials not derived from paper-pulp, or if prevented by continuous ink barriers. SCP-XXXX instances are present in only one side of the sheet they're in, but can easily move to the other side. Infested documents that have been lit on fire, dampened to the point of ink dissolution, or otherwise destroyed in a manner incompatible with writing lose all anomalous properties and are considered neutralized.

SCP-XXXX-1 designates a specific "species" of SCP-XXXX. Species differ in size, shape, behavior, prefered SCP-XXXX-2 habitat and/or ███████. So far, over 100 different SCP-XXXX-1 have been identified; ██ of these have been discovered "in the wild", with the rest forming naturally while on Foundation custody. SCP-XXXX-1 have shown surprising behavioral divergence and complexity; species have been shown to engage in nesting, play, courting rituals, [DATA EXPUNGED]. Note: Any other undocumented behavior is to be immediately reported to a Level 3 researcher.

SCP-XXXX-2 designates an SCP-XXXX "ecosystem". Such ecosystems have complex but well-defined food webs5, and are usually self-sustainable. SCP-XXXX-2 instances are crucial in the formation of new SCP-XXXX-1 instances via mechanisms analogous to evolution and natural selection. They are most commonly found in books, including fiction and non-fiction books, college textbooks (usually about mathematics or topics with wide use of mathematical characters, like physics), notebooks, and [REDACTED].
