Igloo the Almighty's SCP Laboratory

Item #: SCP-XXXX

Object Class: Safe Euclid

Special Containment Procedures: Public access to the site where SCP-XXXX is located is restricted at all times, under the cover story that the structure is condemned and a safety hazard. Security staff stationed on-site are required to patrol the perimeter of the area at all times. Level 3 authorization is required to access SCP-XXXX. As of Addendum XXXX-01, SCP-XXXX is to be placed under full quarantine. SCP-XXXX is to be monitored remotely via surveillance cameras and automated motion alarm systems at all times to prevent physical access. In the event of all instances of SCP-XXXX's locks detaching, Protocol 510-Sweep is to be engaged, confirming the need for remote destruction of SCP-XXXX and any entities that appear through it by any means necessary.

Description: SCP-XXXX is an anomalous structure located within a residence in ███████, California, consisting of an empty 4 m x 4 m x 4 m room accessed through an oak wood door. Subjects entering the room report hearing a voice ordering them to shut and lock the door to SCP-XXXX behind them and feeling an intense compulsion to do so in response, to the point of violence if they are blocked from doing so; no such voice has been recorded, however. Upon locking the door to SCP-XXXX, all materials inside the room are transported into SCP-XXXX-1, and all digital electronic devices are immediately disabled — analog technology, however, remains active even following entry.

Attached to the door of SCP-XXXX is a collection of thirty-six door locks, designated instances SCP-XXXX-A-1 through SCP-XXXX-A-36. Instances of SCP-XXXX-A are all distinct in appearance and material from one another; however, all instances show an inability to be destroyed, damaged, or removed from the door to SCP-XXXX by any means. Only a single, seemingly random instance of SCP-XXXX-A will manifest on the inner face of SCP-XXXX's door at any given time, corresponding to a matching instance on the exterior. The instance of SCP-XXXX-A on the outer face of the door corresponding to the instance on the inner face will detach from SCP-XXXX when it activates, losing its anomalous properties in the process. As of the time of writing, only █ instances of SCP-XXXX-A remain attached to SCP-XXXX.

SCP-XXXX-1 is an anomalous, extradimensional location accessed through transport by SCP-XXXX. This location does not appear to obey basic laws of physics, with the influence of forces such as gravity and friction being significantly diminished or neutralized. Wireless signals and connections remain active within the initial entrypoint of SCP-XXXX-1, but gradually weaken as subjects progress into the location. SCP-XXXX-1 is apparently exclusively inhabited by a species of aggressive, carnivorous entities of varying shapes and sizes, all of which are capable of passively corrupting electronic video and audio. Notable among inhabitants of SCP-XXXX-1 is an entity designated SCP-XXXX-1-A, currently believed to be the largest active lifeform in SCP-XXXX-1. SCP-XXXX-1-A is a quadrupedal, reptilian entity which, though hostile, has expressed sapience and made multiple attempts to communicate. Further information on SCP-XXXX-1 and SCP-XXXX-1-A is detailed in Exploration Log XXXX.

Addendum XXXX-01: As of ██/██/████, following the events documented in Exploration Log XXXX, the compulsory effects of SCP-XXXX have greatly intensified, extending beyond the area of SCP-XXXX to affect all subjects within physical viewing range of its door. Containment procedures have been adjusted accordingly.

Additionally, a recurring phenomenon of harsh, intermittent knocking and scraping noises against the interior of SCP-XXXX has developed since the expedition. The source of these sounds has yet to be identified, and inspections of SCP-XXXX-C through D-Class Personnel have revealed no developments within the room. Potential reclassification to Euclid is pending.

Addendum XXXX-02: On ██/██/████, a small, tattered piece of note paper was recorded being pushed under SCP-XXXX's door from the inside. The item has since been retrieved through automated drone, and SCP-XXXX has since been reclassified as Euclid. Writing on the note paper is crudely scrawled and alternates between several languages, including Persian, Korean and Serbian. Translations of the message on the note read the following:

break the locks and let me in break the locks and let me in breAK THE LOCKS AND LET ME IN
it's coming for me
break the locks and let me in before you go and starve me dead
there's nothing i could hope to do to stop it otherwise
break the locks and let me in before i lose the patience to knock
it'll tear me apart
i need you to stop being afraid of me
because what's chasing me is so much worse
it's hunting me
and when it's done with me, it'll hunt you too
and no locks will hold it

please. i know you could never understand, for you cannot read between the lines the way we can, but please.
it's the end
break the locks and let me in before the monster comes and finds me.
