Background Story
First catalogued by the JustUnleash field unit during a routine sweep of infinite reception lobbies. Ceiling Lung is currently designated Safe and demonstrates behavior consistent with classification Safe. Estimated threat index is 56/100 (MODERATE). The entity primarily mimics ambient HVAC noise to mask approach and has been encountered on 13 separate documented occasions.
Origin
Origin remains [SAFE-LEVEL HYPOTHESIS]. Recovered field recordings suggest the entity may be a manifestation of predator phenomena native to deeper sectors. Cross-reference with parallel sightings in adjacent levels.
Behavior
Primary observed behavior: mimics ambient HVAC noise to mask approach. Secondary cycle on a 23-minute interval.
Containment Procedures
Maintain perimeter of no less than 19 meters. Avoid use of reflective gear. Sector lockdown protocol JU-2A applies if three sightings occur within 24 hours.
Investigation Notes
Sensor logs indicate elevated electromagnetic readings during all confirmed encounters. Theoretical model places this entity within the Sub-Strata stratum.
Survivor Testimony
"It didn't look at me. It looked at where I had just been. By the time I realised, the hallway was already different." — Survivor recording JU-015, redacted operator.
