Item #: SCP-XXXX
Special Containment Procedures: due to its nature containment cannot be achieved.
Discovery: The SCP has come to the Foundation's knowledge after a Senior Researcher had been to a hotel and a notebook materialized in front of him and fell to the ground. The notebook discovered by Senior Researcher K.N.███████ belongs to comic artist G.████████ the notebook has all of his reports making his way through the SCP and one (1) sketch of the inside view of the SCP and one (1) sketch of "The Entity" that roams inside the SCP.
we have successfully managed to send D-Class personnel into the SCP itself.
The SCP can be accessed through [DATA EXPUNGED AFTER 05 COMMAND] before going to bed in a hotel room.
Subjects that have gone through this procedure when they finally sleep wake up in The SCP instead of their original resting place. The SCP has been observed to only take its victims from
hotel rooms and never from anywhere else.
Description: The SCP of the matter is a hotel that has its walls made entirely out of Mirrors and floors out of black marble. The walls in this SCP are erratic and there are corpses lying around at seemingly random places in the SCP.
There is an Entity roaming inside this SCP which has been observed to butcher anyone it sees
and this entity seems to progress through the hotel as a person progresses through it eventually reaching the person. The Entity is approximately 1.74 m tall and black with an orange mist following it in its steps. The Entity eliminates its prey by generally crushing their lower spine leaving them paralyzed, gouging their eyes out, injecting them with a substance that keeps them awake under extremely painful situations and slashing their abdomen open to eat them while they are still alive until it finally reaches their heart or they die of blood loss. The Entity has also been observed using its environment to eliminate its prey like doors and glass panels in hallways.
There are currently 42 floors explored in this SCP. Each floor can be progressed through to the next one by reaching the elevator in a different place than the one before. Since the elevators are in different places and the place is nearly entirely made out of mirrors it is very easy to get lost in here.
The SCP, when entered has a weird and unnerving AC buzz in the background that seems to follow you anywhere you go.
Electrical devices except radios have been observed to stop working inside the SCP.
