Item #: SCP-398 Object Class: Euclid Special Containment Procedures: SCP-398 is contained behind a reverse-airlock style containment chamber locking mechanism consisting of at least three steel doors and an atmospheric reduction system. A minimum of two guards must be stationed at the doors, remaining at a 50 m distance from the entrance to the SCP. Description: SCP-398 appears to all subjects as a hallway of some description; however, details differ between accounts. It is first seen as a hallway with white walls, plain wooden doors twenty (20) metres apart and approximately two (2) metres high, and brass handles, with no special attributes visible. This detail is consistent across all accounts. It was found on location at [DATA EXPUNGED] and upon investigation, a Dimensional Containment Site was set up around it. The remainder of the original building surrounding it is unremarkable and has been demolished as such.
