Development of this article has been discontinued. It is still around for me to salvage old ideas from.


This article isn't done. The majority of my sandbox articles are one-off concepts I never finish, so don't come here looking for anything that wasn't written in one night.

The interior of SCP-XXXX.

Special Containment Procedures: The building containing SCP-XXXX has been purchased by a Foundation front company and closed on the pretense of asbestos contamination. A minimum of three armed security personnel are to keep watch at the entrance site.

SCP-XXXX-A instances that emerge from SCP-XXXX during testing are to be ordered, verbally and through gesture, to return into SCP-XXXX. Noncompliance is to be met with lethal force. Due to the loss of personnel during testing, further tests have been forbidden by vote of the Ethics Committee.

Any entities emerging from SCP-XXXX outside of testing are to be terminated immediately.

Description: SCP-XXXX is a spacial anomaly affecting Maintenance Tunnel 31 of the Internationales Congress Centrum (ICC) conference building in Berlin, Germany. The building was acquired by the Foundation on ██/██/2014 after an investigation uncovered SCP-XXXX.

Testing has revealed that SCP-XXXX consists of a finite spacial loop that may be entered through a door labeled "Wartungstunnel1 31A." Inside of SCP-XXXX, an expanse of semi-regular support pillars extends apparently infinitely in all directions. The door used to enter and exit SCP-XXXX is present on one of these pillars. Other identical doors are present every 2.6 kilometers in an apparent grid, and each door leads to a superficially similar version of the ICC containing multiple SCP-XXXX-A-2 instances.2

SCP-XXXX-A are entities of varying shape, form, chemical composition, and [DATA EXPUNGED]. Upon the entry of a living entity (hereafter "subject") into SCP-XXXX, an indeterminate number of lone SCP-XXXX-A-1 will enter SCP-XXXX through their respective doors. Each SCP-XXXX-A-1 will closely mimic the movement of subjects within SCP-XXXX. Because of this, subjects passing through a door they did not enter SCP-XXXX through will result in an instance of SCP-XXXX-A-1 emerging from SCP-XXXX and into baseline reality. See Addendum 1 for further information.

SCP-XXXX-A-1 and SCP-XXXX-A-2 from the same door are morphologically identical, but -A-2 are able to act freely without any apparent duplication of actions. It should be noted that instances of SCP-XXXX-A-2 only appear on the other side of doors found in SCP-XXXX due to the nature of the anomaly; any creature from another door only enters at the same time as a subject entering SCP-XXXX.

SCP-XXXX-A-1 are hypothesized to be probabilistically or deterministically bound to subjects entering SCP-XXXX.

Addendum 01: Expedition Logs

It should be noted that at the same moment D-94020 opened the door, an instance of SCP-XXXX-A-2 resembling a humanoid scorpion exited from SCP-XXXX and was promptly terminated by present security personnel.
