CLASSIFIED DOCUMENT HXH0K-ECHO. Incident "Kairokat" occurred on 02/30/1987, involving a non-Euclidean geometry anomaly at the Czocha Castle ruins. Witnesses reported a "folded" corridor, where doors led to recursive iterations of the same hallway. Investigation revealed cryptic murals depicting impossible structures, which seemed to "bleed" into adjacent dimensions. Temporal cartographers detected a localized distortion, causing clocks to "stutter" and reset to arbitrary timestamps. The anomaly was contained using a bespoke "chrono-synch" protocol, but residual effects persist, causing intermittent "ghost echoes" in nearby settlements. Clearance level: EYES ONLY. Distribution restricted to authorized personnel with HXH0K clearance.
