Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX is to be contained in a standard 4 x 4 meter, ventilated, solid white room outfitted with a two-way mirror for observing SCP-XXXX while it is alone.
At any given moment, there should be at least 2 personnel assigned to watch SCP-XXXX, with both individuals copying anything that may appear on SCP-XXXX. Should any language appear on SCP-XXXX’s surface in which any of the assigned personnel are not fluent in, then said personnel should be immediately cycled out for an individual who is fluent in the language. Should a period of more than 3 hours go by without any writing appearing on SCP-XXXX, a staff member should immediately enter SCP-XXXX’s containment chamber in order to “check in” on SCP-XXXX’s wellbeing. The staff member entering the containment chamber is to verbally answer any mundane questions SCP-XXXX should pose during this procedure. Any confidential question posed by SCP-XXXX to a staff member is to be met with a brief verbal explaination to SCP-XXXX on as to why the question cannot be answered. Never under any circumstance should SCP-XXXX be ignored or lied to while communicating with a staff member.
5 times every day, at aproximately 06:00, 10:00, 14:00, 18:00, and 22:00 local time, 1 Class-C personnel is to enter SCP-XXXX’s containment chamber for a scheduled conversation session. The individual conducting the session is to talk to SCP-XXXX as if they were either personal acquaintances or strangers meeting for the first time, depending on the history between the one conducting the session and SCP-XXXX. Conversation sessions should last no less than 30 minutes, and all dialogue between the individual and SCP-XXXX is to be written down and logged for future reference by the personnel currently assigned to monitor SCP-XXXX.
If SCP-XXXX should begin to produce a visible amount of chalk powder, all ventilation systems are to turned on immediately. In the event that SCP-XXXX is completely obscured from view due to its production of chalk powder, 2 Class-D personnel equipped with respirators and radios are to enter the containment chamber and attempt to convince SCP-XXXX to cease its production. Any writing that is observed is to be relayed via radio to the personnel currently assigned to monitor SCP-XXXX. Should SCP-XXXX ever come in physical contact with the walls or floor of its containment chamber and begin to convert the material, Class-D personnel are to enter the containment chamber and secure SCP-XXXX with steel “wolf jaw” style tongs. SCP-XXXX is then to remain suspended above the ground and away from the walls by any means necessary until SCP-XXXX is docile.
Description: SCP-XXXX is a 1.5 meter long and 1 meter tall double sided blackboard with a frame made from red oak. Typically SCP-XXXX is affixed to a wooden stand that allows it to be rotated vertically 360°. Despite its mundane appearance, SCP-XXXX has a number of anomalous properties, the first of which to be noted is its ability to write on itself. This writing is not done through any visible medium, although analysis has determined that the material used in these writing is in fact chalk. SCP-XXXX also has the ability to “erase” any writings or drawings upon its surface, including those not orginating from SCP-XXXX. During “erasing” the material that the soon-to-be-erased drawing or writings simply vanishes, with no trace of its existence left behind.
The second and foremost important anamalous property SCP-XXXX possesses is its sentience. SCP-XXXX can perceive auditory, visual, and tactile stimuli, along with the ability to directly communicate in human language by writing on its surface. The languages SCP-XXXX has shown the ability to understand and communicate in have included
• English
• Mandarin Chinese
• Russian
• Hungarian
• German
• Italian
• Japanese
• Greek
• Polish
• Spanish
It also has able to recognize itself in mirrors, use critical thinking skills, show complex emotion, and express artistic interpretations of ideas. Along with its very human qualities, in many aspects SCP-XXXX’s intellect seems to vary from outright unexplainable to simply extremely implausible. Examples of this include:
• solving advanced level calculus problems in less than a minute, despite taking 7 minutes to calculate the product of the numbers “12” and “3” just 4 days before this event.
• being able to communicate its exact coordinates on a GPS.
• Knowing what languages an individual is fluent in by simply “looking” at them.
• Replicating an entire diagram of the human skeleton after “examining” an x-Ray for 5 seconds
SCP-XXXX has the capibility to turn any matter it is in contact with into a fine powdered chalk. So far, this ability has been tested the least due to the inherent dangers associated with it. However, it has been observed that when touching solid matter, the matter is converted into chalk at a rate of 1cm2/second 2 dimentionally in all directions, and 0.2cm3/second 3 dimensionally in all directions.
SCP-XXXX is generally friendly with staff, and is often very cooperative with foundation as a whole, seemingly understanding why it is in containment. In light of this, SCP-XXXX has formed a very strong bond of friendship with Dr. Szabó and seems to greatly enjoy communicating with him. However, SCP-XXXX has shown an immense desire for human contact, and will do anything for attention. After [Incident XXXX-A] Human contact with SCP-XXXX is to occur for a minimum of 2 hours and 30 minutes each day, preferably with Dr. Szabó, but SCP-XXXX has shown a willingness to communicate with other personnel
