[Bibliography item label not found.]*Item #:** SCP-8093
Object Class:Euclid
Special Containment Procedures: SCP-8093 is to be securely installed in a door frame. The door frame is to be monitored by at least two security personnel at all times. SCP-8093 must be checked regularly for any signs of damage or tampering. Should SCP-8093 need to be moved, it must be relocated to a new door frame within ten minutes to prevent fragmentation. Any instances of SCP-8093-3 encountered must be contained and handled according to their sentience status.
Description: SCP-8093 is a six-foot white door made out of wood, featuring a distinctive red door knob. When opened, SCP-8093 serves as a portal to a pocket dimension that is an endless hallway of doors. Each door within this hallway is unique and, when opened, leads to various times, places, or universes. Notably, the appearance of each door within the hallway correlates with the location it leads to; for example, a destroyed door might lead to an abandoned house.
Inside the pocket dimension, text is inscribed on the floor in the native language of the observer. The inscription reads: "Welcome to the door to all doors. If you are stuck or don't know where you are just knock on the ground three times to go to the door you came in from . If you are stuck in a different world, knock three times on the door you came in, and it will open a portal back here."
These instructions function precisely as described. Upon knocking on the ground three times, SCP-8093-2, a humanoid figure composed of black gas, will appear and transport the individual back to the original door they entered through. SCP-8093-2 only manifests when summoned in this manner.
Various hostile entities, designated as SCP-8093-3, have been observed within SCP-8093. The origin of these entities is currently unknown; they may originate from within SCP-8093 or have access to similar doors. SCP-8093-3 entities have been known to breach into our world via SCP-8093. In the event of encountering SCP-8093-3, the entity is to be detained, and SCP-8093 should be relocated to a different door frame. Sentient SCP-8093-3 entities are to be interrogated and housed in individual containment cells. Non-sentient entities are to be subjected to further research and experimentation.
SCP-8093 has the capability to be moved to different door frames, which alters its position within the pocket dimension. If SCP-8093 is not placed within a new door frame within ten minutes of removal, it will break into three to five pieces. Subsequently, within five to ten hours, the nearest door will transform into SCP-8093.
Addendum 8093-1: Due to the unpredictable nature of SCP-8093-3 entities and the potential risks they pose, all personnel interacting with SCP-8093 are required to undergo specialized training and must adhere strictly to containment protocols. Further research is ongoing to understand the full capabilities and origins of SCP-8093 and the entities it houses
