**CLASSIFIED BRIEFING DOCUMENT 7421-s2r4w6** Eyes only: Clearance level 6 and above. Incident "Kairostatic Rift" occurred on 2/4/1966, resulting in a 6-hour, 42-minute temporal dissonance. Architectural analysis reveals a labyrinthine structure, dubbed "The Wraithspire," materialized within the rift. Its walls pulsed with a mesmerizing, crimson luminescence, as if fueling an imminent reality recalibration. Witnesses reported feeling an intense, creeping "chrono-displacement" as the structure imploded, leaving behind only cryptic, hexagonal residue patterns. Further investigation is hindered by an inexplicable, recursive erasure of all related records, hinting at a deeper, more sinister anomaly. **FILE PURGED 4/6/1978**
