Item #: SCP-003
Object Class: Euclid
Special Containment Procedures: SCP-003 is to be maintained at a constant temperature of no less than 35°C and ideally kept above 100°C. No living multicellular organisms of Category IV or higher complexity may be allowed to come into contact with SCP-003.
In event of total power failure, if SCP-003-1 begins to increase its mass, assigned personnel must engage in skin contact with SCP-003-1. Ideally, personnel may use their body heat to return SCP-003-1 to above the critical temperature; however, skin contact must be maintained even in event of SCP-003 reaching activation temperature, lasting at minimum until SCP-003-1 advances fully to its second growth stage.
Personnel who enter SCP-003's containment area must first be examined for body parasites of Category IV or higher complexity, and sterilized if such organisms are present. All personnel who have come in physical contact with SCP-003-1 are to immediately report for sterilization afterwards.
SCP-003-1 must not be removed from SCP-003-2 except in case of emergency procedures detailed above. Any significant change in SCP-003-2's rune activity (including pattern, frequency, or color) should be reported within three (3) hours of occurrence. Cessation of rune activity must be reported immediately. SCP-003-2 must be supplied with power via the source designated Generator 003-IX at all times.
Description: SCP-003 consists of two related components of separate origin, referred to as SCP-003-1 and SCP-003-2.
SCP-003-1 appears to be composed of chitin, hair, and nails of unknown biology similar to SCP-████ and SCP-████, arranged in a configuration similar to that of a computer motherboard. Testing reveals SCP-003-1 to predate earliest known circuit boards by a factor of thousands of years. SCP-003-1 is considered sentient but not actively dangerous except under certain conditions.
SCP-003-1 was found on a stone tablet, SCP-003-2, on which it currently resides. The runes on SCP-003-2 are not part of any known language, and emit pale, flickering light patterns.
SCP-003-2 is controlled by a (non-biological) internal computer, the contents of which are mostly inaccessible without risk of damaging SCP-003-2. SCP-003-2 is capable of controlled emissions of radiation, including heat, light, and anomalous radiation types. SCP-003-2 contains an internal power source of an anomalous nature, which appears to have been losing power since several centuries before discovery.
It is considered probable that SCP-003-2 was created for the purpose of containing SCP-003-1. Partially interpreted data recovered from SCP-003-2 may refer to a past and/or potential future LK-class restructuring event caused by SCP-003-1.
SCP-003 was located by remote viewing team SRV-04 Beta. It appears possible that SRV-04 Beta was deliberately contacted by SCP-003-2. Other organizations have also been alerted to SCP-003's existence, possibly by similar means. Despite this activity, SCP-003-2 does not appear to be sentient, based on its lack of reaction to M03-Gloria analysis and procedures.
When SCP-003 drops below the temperature of 35°C, both components react.
First, SCP-003-1 enters a growth state characterized by an exponential increase in mass. This growth state consists of two stages. In both stages, SCP-003-1 partially fuels its growth by converting matter around it, starting with any surrounding inorganic material, including atmospheric elements, then nonliving organic material, including cells of dead skin, hair, chitin, enamel, keratin, and other biological materials.
The first stage is always the same. SCP-003-1 will first increase its mass, then take a form similar in shape to an ophiuroid (brittle star) of fifteen meters in diameter (including what appears to be a central processor of three meters in diameter). It will form sensory organs that appear to scan its surrounding environment, and will partially convert the area around it to an unidentified anomalous substance (SCP-003-2 seems immune from conversion).
