ENTITY-XXXX is to be monitored within Sector-5 of the Backdoor complex. All access points leading to its territory must be sealed with reality-stabilizing alloys and monitored by motion-triggered cameras.
Personnel encountering ENTITY-XXXX must immediately activate phase-lock devices and avoid direct observation. No more than three (3) personnel may be deployed for observation at any time.
WARNING: Do not attempt to follow ENTITY-XXXX through "threshold events" - recovery of affected personnel has proven impossible.
ENTITY-XXXX is a semi-corporeal presence that manifests in areas where the Backrooms' architecture becomes unstable. It appears as a humanoid silhouette with distorted proportions, leaving behind temporary spatial anomalies.
Documented effects include:
ENTITY-XXXX demonstrates purposeful movement patterns, though its objectives remain unknown. It appears drawn to areas with high noclipping activity and has been observed interacting with certain walls for extended periods.
Of particular concern is its apparent ability to "infect" locations - areas it frequents begin exhibiting similar reality distortions even in its absence.
During Incident XXXX-7, ENTITY-XXXX was observed phasing through a researcher. The subject reported feeling "cold absence" before developing spatial dyslexia and losing the ability to perceive right angles. Subject terminated 72 hours later after attempting to "walk through" a solid wall.
