Item #: SCP-419

Object Class: Safe

Special Containment Procedures: SCP-419 is to be kept within a steel alloy1 frame and attached to its accommodating wallspace. No covering or casing is present. SCP-419 currently resides in a room inside Site 33, dimensions 3m x 5m x 4m. All of the walls in the containment unit, including the one behind SCP-419, are made of a mesh of plastic, steel, and concrete. On the north-facing wall of the containment room is a viewing bay2 leading to another room with the same dimensions. Two guards are positioned outside of the containment room near the viewing bay and are authorized to use lethal force. They shift every three (3) hours. SCP-419 must be cleaned daily with ordinary window-cleaning supplies. Any personnel tasked with maintenance must not suffer from acrophobia. Constant monitoring of SCP-419 must take place from the viewing bay in order to ensure that the view through SCP-419 does not change significantly. In the event that it does, contact Site Director █████. Access to SCP-419 is prohibited except under special circumstances and permission from Site Director.

Description: SCP-419 is a large pane of reinforced glass 1.5m x 3.6m x 7.6cm in dimensions. One side of SCP-419 does not allow light to pass through. Instead, it displays a view of what appears to be an extradimensional urban environment. This phenomenon is only present when viewed directly by a human subject. Photographs, motion sensors, and vision-enhancing objects such as glasses or contacts all act on SCP-419 as if it were a mirror. The scene viewed through SCP-419 appears to be outside but lacks any natural lighting, regardless of the time it is viewed. No super-terrestrial forms (such as celestial bodies) are visible. The view would appear to originate from a vantage point high above ground level. Approximately 800 lux of light emanates from SCP-419 despite the lack of a light source. The source of this phenomenon is theorized to be whatever environment SCP-419 displays. Light from SCP-419's testing chamber does not affect this scene.

The buildings visible through SCP-419 appear similar to those of the Victorian architectural period. However, they tend to have unusual, almost imperceptible changes that make them appear warped or twisted, or occupying spaces they should not. Much, if not all of the area viewed through SCP-419, is non-Euclidean. Estimates of the size of this city vary depending on when it is viewed and have ranged from approximately twelve square kilometers to over sixty. A multitude of neon lights and signs have been noted but are not in any known language.

Organisms have been viewed walking, albeit only en masse due to their relatively small size. Their actual size is currently unknown due to the lack of a scale. They appear to be humanoid and dark red in color; however, the lack of available computerized assistance and the obvious flaws in the human eye does not allow for a higher level of detail to be ascertained. Due to their seemingly advanced level of technology, the running theory among researchers is that this is not their actual skin color, but rather their clothing.

Additional Description:

{+} Prior to Incident 419-B (Obsolete)

{-} Prior to Incident 419-B (Obsolete)

Occasionally, large metallic constructs have been viewed moving through the "streets" followed by large masses of the humanoids. During these occasions such processions compose all of the visible movement within the city. Dr.█████ notes that these processions are highly reminiscent of military marches due to their extremely geometric nature and constant pace.

{+} After Incident 419-B

{-} After Incident 419-B

Following Incident 419-B, the entire landscape viewed through SCP-419 has changed drastically. Many of the buildings appear to be lit on fire or smoldering, much of the ground is covered in rubble, and there is almost no visible movement from the previously-described red humanoids. However, what appear to be similarly shaped dark blue humanoids have been observed performing similar processions. Approximately ██% of the buildings consistently observed before Incident 419-B have collapsed. Visibility has also been significantly obscured by an opaque gas, theorized to be smoke. Upon closer inspection, a multitude of dark gray figures are visible in the streets, but remain stationary. The implications of this event are unknown.

Note 9-27-13: SCP-419 seems to be aging at an abnormally fast rate. We currently believe this is due to the atmosphere on the other side, though we obviously cannot test it to know for sure. At this speed, SCP-419 could become non-functional as soon as 2019. What this will mean, we do not yet know.
