In the autumn of 1987, the residents of Hollow Creek began disappearing one by one. No bodies were ever found. The only evidence: a series of cryptic symbols carved into the bark of the ancient oak at the village center. Local folklore speaks of the Hollow Man -- a spectral figure seen walking the mist-shrouded paths between the trees, visible only in the peripheral vision of those who would soon vanish.

Analysis of the bark carvings reveals a pattern consistent with pre-Celtic ogham script, though several characters remain unidentified. Spectral analysis of soil samples taken near disappearance sites shows anomalous electromagnetic readings -- frequencies that correspond to no known natural or artificial source. The investigation remains open, though Hollow Creek itself was abandoned in 1989.

The Eddenmoor Lighthouse ceased operations in 1962, yet locals report its beacon firing in irregular, non-standard patterns during new moons. Maritime radio operators have intercepted what appears to be encoded transmissions originating from the lighthouse frequencies -- transmissions that predate modern encoding algorithms by decades, yet resist all classical cryptanalysis.

Frequency analysis of the intercepted transmissions reveals a non-random distribution inconsistent with atmospheric noise. The pattern exhibits a 29.5-day periodicity aligned with the synodic month. A partial decryption using a modified Vigenere cipher with the key "PHOSPHORESCENCE" yielded the fragment: "THE KEEPER WATCHES STILL." No lighthouse keeper has been assigned to Eddenmoor since its decommission. Physical inspection of the lighthouse reveals functional but impossibly maintained equipment -- no dust, no corrosion, no signs of human presence.

Every seventeen years, the ravens of Blackmoor Heath gather in a formation that, when plotted from aerial photography, traces the outline of a structure that does not exist on any map or survey. The formation was first documented in 1938 by ornithologist Dr. Elspeth Crane, who noted the mathematical precision of the birds' positions corresponded to no known flocking algorithm.

Cross-referencing the aerial formations with geological surveys reveals the outline matches a structure consistent with late Iron Age ceremonial architecture -- though ground-penetrating radar shows no subsurface remains. Dr. Crane's original field notes, recovered from the Whitmore Archive, contain a margin annotation in an unknown hand: "They remember what the ground has forgotten." The next predicted gathering is 2040. A permanent monitoring station has been established.
