CLASSIFIED DOCUMENT: EYES ONLY PROJECT CODE NAME: bb1lz INCIDENT REPORT: The Kalthari Anomaly (1953) A labyrinthine structure materialized in rural Hungary, defying cartographic records. Witnesses described a "gutted prism" with doors that "sluiced" into non-Euclidean corridors. Entrants reported experiencing cryptic "folded time" episodes, where hours collapsed into minutes. The structure vanished after 37 days, leaving behind only a residue of "spectral rust" and an unexplained, lingering echo of forgotten scents. All attempts to recreate or understand the anomaly have failed. Recommendations: Continue monitoring for similar events, and reclassify all related documentation as "Erebus-Level" confidentiality.
