Class: Keter
XXXX is an unknown dark being that has never managed to be contained by the S.C.P foundation. XXXX has been spotted all over the world in many different environments, indicating that it has some form of extremely efficient travel. The size of XXXX can change drastically. XXXX has a tendency to mess with humans by making noises deep within the darkness. XXXX does this only for fun. However, if a human does walk into the darkness where XXXX is located, XXXX will kill the human by [REDACTED], [REDACTED] or the human will die from cardiac arrest.
XXXX is known to have a hatred for light. People who have heard the noises of XXXX in the darkness, and in curiosity turn a light on/shine a torch towards XXXX. XXXX will then destroy the light source and proceed to stab into the victim with its [REDACTED].
XXXX will continue stabbing until victim is deceased. It is rare that the foundation locates the body.
XXXX will torment people in the darkness by making noises like kids laughing, grunts, rustling, and kids crying. People who have managed to get away from XXXX and make it to a well lit room, will not be harmed until sleeping. When the victim falls asleep, XXXX will appear in the darkness of the victims mind, and will proceed to [REDACTED] the victim in their sleep causing the victim to experience [REDACTED].
There have been many instances in which XXXX has lured in pregnant women with the sounds of crying children, and proceeded to [REDACTED]. It then take the fetus out of the woman, Storing it in my own personal void. This is the origin of the childlike cries that emanate from around XXXX. Designated XXXX - 2. If the woman is not pregnant however, XXXX will [REDACTED] and proceed to use their body as a form of incubation pod, allowing XXXX - 2 to grow to a sufficient size for [REDACTED]. victims that XXXX - 2 find are used as fuel for the incubation period.
There has been many times when XXXX has just about been contained by the foundation. In one occurrence a d - class personnel was told to shine a super strong flashlight at XXXX from two hundred metre's away. This made XXXX charge towards the d - class personnel. The d - class personnel then ran into the dark box with only one door that had been constructed specifically for XXXX. As the d - class personnel screamed, the door was closed, the box was taken back to [DATA EXPUNGED] for examination.
When researchers looked inside the box there was no sign of XXXX. The main theory is that XXXX managed to exit out of the door as fast as darkness itself.
