The bathtub containing SCP-4517. Contents redacted.

Item №: SCP-4517

Containment Level: Safe

Special Containment Procedures: The apartment housing SCP-4517 has been purchased by the Foundation and fitted with reinforced doors and windows, as well as internal surveillance. The building's remaining tenants are to be considered a Class-G monitoring priority, and future resident selection is to be weighted in favour of those with no history of paranoia, delusions, or abnormal curiosity. All security footage for the building is to be supplied to RAISA personnel for analysis and archival.

Description: SCP-4517 is located in the bathtub of a three-room apartment in Leeds, England. It measures 170 centimetres in length, has a mass of 55 kilograms, and possesses no subjective properties or qualities. While human comprehension of SCP-4517 is obtainable, the only accurate descriptions of it not based on objective measurements refer indirectly to the inability to describe it. Researchers are advised to note that SCP-4517 is not indescribable, as that would allow it to be described as such — rather, it simply does not possess any qualities that are themselves able to be described1.

𝒩ness (as it has been termed by DoMc researchers) is an objective-relative (and presumably ordinarily subjective) quality possessed by all existent entities, quantifiable by comparing the entity in question with SCP-4517, which acts as a baseline with an 𝒩ness of zero. Research into the exact nature of the quality is ongoing. For the purposes of determining how 𝒩 various objects are in relation to the anomaly, Balance.aic2 has been designed to compare live observation of SCP-4517 with assorted photographs, videos, and textual descriptions. Certain pertinent results of this process are included below.
