Background Story
First catalogued by the JustUnleash field unit during a routine sweep of drywall maintenance shafts. Patient Yellow is currently designated Euclid and demonstrates behavior consistent with classification Euclid. Estimated threat index is 91/100 (EXTREME). The entity primarily mimics ambient HVAC noise to mask approach and has been encountered on 15 separate documented occasions.
Origin
Origin remains [EUCLID-LEVEL HYPOTHESIS]. Recovered field recordings suggest the entity may be a manifestation of experimental subject 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 33-minute interval.
Containment Procedures
Maintain perimeter of no less than 54 meters. Avoid use of reflective gear. Sector lockdown protocol JU-7C 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-047, redacted operator.
Field Notes — Restricted
During incident ████████████, subject JU-047 was observed ████████████ before withdrawing into drywall maintenance shafts. Cross-link withheld pending clearance level 3.
