Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: SCP-XXXX's external entrances and exits are to be blocked off from civilian access, with the public explanation that it is a condemned building. Mentions of SCP-XXXX are to be censored from the internet, and surviving former occupants of SCP-XXXX are to be given Class-A amnestics as they are found. Persons found approaching SCP-XXXX with intent to enter are to be given Class-C amnestics and turned away.

Interaction with SCP-XXXX-A instances is forbidden1. Expeditions into SCP-XXXX may be approved by the Lead Researcher on a case-by-case basis.

Description: SCP-XXXX is a five-storey apartment building located at ██, ███████ Drive NW in Edmonton, Alberta, Canada, housing thirty-six one-bedroom units. The building also contains a basement that lacks units. The building was completed in September 2014 on a plot of undeveloped land that was previously home to several SCP-XXXX-A entities.

During the night, a number of corporeal entities (SCP-XXXX-A) will materialize in the common areas of the building and proceed to move around SCP-XXXX, including into units that have open doors. SCP-XXXX-A instances are not visible from the exterior of SCP-XXXX, and have not been known to exit the building.

These entities are identified numerically from SCP-XXXX-A1 through SCP-XXXX-A13, with each entity having a unique appearance2. Each instance has a unique behavioural pattern, with most having locations in the building they prefer to wander. SCP-XXXX-A instances acknowledge environmental stimuli such as bright lights and noise, and will universally retreat from such stimuli. For a full list of SCP-XXXX-A instances and their behavioural profiles, see 'SCP-XXXX-A Profiles'.

SCP-XXXX-A entities are believed to materialize and de-materialize when out of view, and are currently not believed to reside in a physical location in SCP-XXXX.

Interaction with an instance of SCP-XXXX-A will cause the subject to slowly transform into an instance of SCP-XXXX-A over the course of 6 hours, during which the subject will feel a strong urge to return to SCP-XXXX. If the subject is unable to reach SCP-XXXX before they fully transform, they will dematerialize almost instantaneously.

SCP-XXXX was discovered following repeated reports of nightly intruders to Edmonton police. The building was subsequently purchased from the original owner and contained.
