Background Story
First catalogued by the JustUnleash field unit during a routine sweep of broken vending alcoves. Strain Δ is currently designated Keter and demonstrates behavior consistent with classification Keter. Estimated threat index is 65/100 (HIGH). The entity primarily engages only when the wanderer's heart-rate exceeds 110 bpm and has been encountered on 31 separate documented occasions.
Origin
Origin remains [KETER-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: engages only when the wanderer's heart-rate exceeds 110 bpm. Secondary cycle on a 60-minute interval.
Containment Procedures
Maintain perimeter of no less than 33 meters. Avoid use of high-frequency audio. Sector lockdown protocol JU-3D 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 Periphery 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-051, redacted operator.
