rating: 0+x

Item #: SCP-XXXX

Object Class: Thaumiel/Keter

Special Containment Procedures: SCP-XXXX is to be kept in a three room residential containment unit furnished to it's liking. One room, containing one (1) bed, three (3) tables, two (2) bookshelves, one (1) chair able to roll around the room and one (1) computer setup in accordance with specifications SCP-XXXX-A requests. The second room containing one standard bathroom with the third room containing a small kitchen that must always be kept fully stocked at the start of a new day.

SCP-XXXX is permitted access to Level-0 and common areas provided that SCP-XXXX-A notifies personnel of Level-2 clearance ahead of time and is accompanied by two (2) security personnel during its time outside of its room.

SCP-XXXX is permitted visits outside of the facility for walks and recreational activities provided that SCP-XXXX-A notifies personnel of Level-4 clearance ahead of time and is accompanied by four (4) security personnel familiar with it.

SCP-XXXX-A may not be damaged by site personnel or other SCPs under any circumstances outside of testing situations. SCP-XXXX-A is not to be approached if damaged under any circumstances and doing so will lead to immediate disciplinary measures as is deemed appropriate by the Site Director.

SCP-XXXX-A is permitted access to games, media and reading material upon request after it has been approved by security staff and is also permitted access to the internet but is not permitted to "Leave comments." and "Take an active part in conversations online." as it puts it unless said comments have been approved by security staff beforehand.

SCP-XXXX-A is to choose it's own clothing and no effort is to be made to change what it chooses to wear as this seems to agitate it greatly.

If SCP-XXXX-B manages to leak out all individuals beside SCP-XXXX-A are to remain at a distance of at least twenty (20) meters away from it until SCP-XXXX-A has declared that it is safe to approach once more.

Description: SCP-XXXX-A is a Caucasian biologically male individual between 20 and 30 years of age. Is it exactly 172 centimeters tall and weighs 60 kilograms with a moderately thinly built form. It is largely covered by purple tattoos that follow a swirling pattern. These tattoos are most prominent on it's arms and chest region ending at it's neck. It also appears to posses a red discoloration in it's irises which cause them to appear red in most instances though they shift into purple when SCP-XXXX-A is agitated.

SCP-XXXX-A claims to be over two hundred years old but to also have been part of events from long before the eighteenth century. It is able to provide detailed descriptions of these events ranging from the fall of Rome to Nazi Germany and the opium wars in China. These descriptions mostly coincide with historical records and do not give cause for doubt. It is yet to be proven that SCP-XXXX-A has ever lied.

SCP-XXXX-A is, for all intense and purposes, not possible to kill but does express feel pain. It will gradually reassemble itself, restoring any damage done. Speed depends on severity of damage in amount, not complexity of the part damaged. A small cut only requiring ten seconds with extensive damage requiring a few minutes but never more than an hour.

SCP-XXXX-A acts as the host and container of SCP-XXXX-B as it resides in SCP-XXXX-A's blood. SCP-XXXX-A does not seem to be able to control SCP-XXXX-B to any degree beyond calling it back within itself.

SCP-XXXX-B seems to be a parasitic corruption that possess SCP-XXXX-A. It has no tangible source, simply forming out of any tissue that does not naturally remove itself from SCP-XXXX-A. It's made up of what seems to be a purple semi sentient thick sludge able to deform itself to move across barriers and reach for whatever it targets at the moment. The "Taint", as SCP-XXXX-A calls it, is able to consume biological materials and grows incredibly quickly, attaining much more mass than it consumes. It reaches a tipping point when surpassing fifty cubic meters in mass and is at this point able to consume inorganic materials of any kind.

SCP-XXXX-B is able to cling to any surface, however dies quickly if not able to continue consuming until it has grown to it's stable size of one cubic meter. Storage in vials has shown that it can survive for extended periods of time if not in contact with gases, storage in vacuum has been proven possible for extended periods of time. The longest recorded is six thousand (6 000) hours, or two hundred fifty (250) days. This time has been increasing with every test. It is assumed that SCP-XXXX-B is adapting and improving over time to adjust to the new environment.

SCP-XXXX-B seems able to learn even if not directly connected, consuming and adapting new properties. It has yet to be tested if SCP-XXXX-B can adapt anomalous abilities as well, though there is no reason to doubt this.

Addendum: SCP-XXXX was collected in ██████ after having reassembled itself when an accident caused a large quantity of I-beams, weighing approximately fifteen tons, to fall from the fifth story of a construction site to completely crush it. First respondents and witnesses where partially hit by SCP-XXXX-A's biological material which in turn caused SCP-XXXX-B to form, killing and consuming the individuals in question as shown by a security camera located on the opposite side of the street.
