SCP-087 (The masked man)

ABOUT
SCP-087 is a Euclid-class object under the SCP Foundation's containment. It is a humanoid face that appears as some sort of paranormal entity in the eldritch staircase SCP-087.

PERSONALTY
SCP-087 is an endless staircase, cloaked in darkness. Lights can be used, but light sources above 75 watts will prove ineffective, as SCP-087 seems to absorb excess light.

Throughout the staircase, the cries and wails of what sounds like a small child are heard. It is unknown if SCP-087-1 is responsible for these cries, as there is no way to follow them or get any closer to the source, even when SCP-087-1 appears. If SCP-087-1 is the source, it is unknown if the cries are legitimate sadness and fear or a lulling tactic to lure victims to it.

In every documented exploration of SCP-087, every subject has witnessed SCP-087-1 appear nearby. It will either stare at them from the darkness, causing mental degradation, or lunge at or chase them through the stairwell in an extremely violent and aggressive manner. Communication disruptions have been caused by SCP-087-1, as those who view it become extremely frightened and often drop any communication equipment they are carrying in their attempt to flee.

Many personnel have disappeared inside SCP-087 and never returned, and it is unknown if SCP-087-1 is the cause of their disappearances/deaths. SCP-087-1 also appears to be aware of the Foundation's presence, as it will stare into discarded video equipment. Personnel that manages to escape SCP-087 and gets back to the top often have long-lasting mental issues and physical fatigue.
