SCP-XXXX, upon discovery.
Description: SCP-XXXX is a door and door frame that appears to be made out of oak wood with no anomalous properties by itself. However, when opened it's revealed that the door seems to lead to an endless black void, it has been theorized that this void seems to be a pocket dimension of some sort, though being a black void it has been reported that subjects can still feel the floor as if it was still there. SCP-XXXX has the ability to draw people in and confuse them
(see Addendum-XXXX-A). Once entered it is impossible to exit the pocket dimension as the door locks and is impossible to open through any means. After estimated 1-5 minutes in SCP-XXXX, SCP-XXXX-2 manifests.
SCP-XXXX-2's true physical description is currently unknown though, yet a figure has been seen looming throughout the void and has been seen described to be a figure vaguely in the shape of a semi-transparent human. SCP-XXXX-2 seems to be very hostile and seems to cause auditory hallucinations which affect his victims causing mental degradation, victims feel feelings such as helplessness, loneliness, and being watched. SCP-XXXX-2 toys with its victims for 3 hours - 7 hours after manifesting and will then attack killing them, it has been found that SCP-XXXX-2 bludgeons its victims until incapacitated and then proceeds to strangle them until they die. Upon death, the victim's corpse will then be forcefully removed through unknown means. Multiple objects which are assumed to be past victims of SCP-XXXX-2 have been found, showing that objects are able to remain inside of SCP-XXXX, though moderately worn out. Objects that have been found inside of SCP-XXXX are the following:
1. A backpack often used for hiking, no contents were inside.
2. A radio found to be from Researcher ███████.
3. A human [DATA EXPUNGED].
4. A blood-stained unintelligible note, DNA was traced back to someone named
█████ █████████ who was reported missing 3 months before discovery.
Addendum-XXXX-A: on █/██/████, SCP-XXXX has been able to kill █ Scientists and
█ security guards. SCP-XXXX is not to be approached due to the possible loss of more personnel
from on, only Class-D's are to enter SCP-XXXX's containment chamber to avoid more loss of important personnel. -Dr. ███████
