Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: The object is currently held within a securely locked concrete cell. This cell can only be opened via level 3 or higher access, or permission from a higher level researcher. No other containment procedures are required. Currently, 2 instances of SCP-XXXX-2 exist. These instances are secured in hermetically sealed cells at site-[REDACTED]. Growth of SCP-XXXX-2 is to be suppressed by rapid controlled exposure to extreme temperatures of up to 200-300 degrees Celsius every 5 hours, for about 10-15 minutes.
Description: SCP-XXXX is a severely worn kitchen knife coated in rust. The blade is constructed of steel, and measures approximately 10 inches. The hilt of the object measures exactly 5 inches. The object possesses engravings on the hilt which read "To be bound by blood is to ascend."

The effects of the object are activated through a specific process. The process required to engage activation of the objects effects was discovered in the contents of the unlabeled tape found with the object. Upon replication of the process depicted in the footage, the objects anomalous properties were confirmed. The contents of the tape feature 2 individuals of indeterminate age and gender engaging in a ritual, in which the 2 unknown individuals use the object to slit their wrists. The individuals then proceed to consume one another's blood. The tape ends after a black screen featuring the same text on the object in white appears for 10 seconds. After replicating the process using the object, an instance of SCP-XXXX-2 is successfully created after 24 hours.

The object and tape were discovered when the disappearance of a young couple was reported by neighbors in [REDACTED]. The foundation was contacted when an instance of SCP-XXXX-2 was discovered by the local authorities. The home still contained the couples belongings, though the neighbors report they had been gone for 2 months. In the upstairs bedroom. The object was discovered, along with a camera, the tape, and the first recorded instance of SCP-XXXX-2.

SCP-XXXX-2 is a large mass of skin and muscle, which shows no signs of sentience or consciousness. The mass will steadily rise and fall, as if it is "breathing." The mass, while not being toxic or directly harmful, can prove to be dangerous if left unattended. If left unchecked for prolonged periods of time, the mass will grow at an accelerated rate, quickly covering the walls, floor, and ceiling of a room. The mass has proven to be able to completely cover a small room in less than 2-3 hours. Extreme heat has been proven to be highly effective at preventing and reverting the growth, but cannot destroy SCP-XXXX-2 completely. As of now, no known methods have proven to be capable of completely destroying or killing the mass. DNA tests have shown that, as expected, the mass consists of the two subjects with which the ritual was preformed. After testing the first instance, the two individuals involved were discovered to be Mr. and Mrs. [REDACTED]. It is as of yet unknown how the couple came into possession of the object.
