Clara Vance vanished on Blackwood Ridge in October 2023 while researching rare moss. Despite an extensive search, rescuers found no trace of the meticulous young botanist. Her father, Thomas, remained near the mountain long after others lost hope, carrying her photograph through the passing seasons. Then, in November 2026, Clara appeared at an eastern ranger station, exhausted, scratched, and clutching a damaged leather notebook. Sheriff Ethan Miller arrived to find the woman he had once searched for.

But Clara offered no comforting explanation. She said she had spent those missing years beneath the mountain and insisted that someone—or something—knew she had escaped. Before Miller could understand her warning, the station lost power. Clara recoiled from the flashlights, claiming their pursuers could see the beams. Three deliberate knocks sounded underneath the floor. Her return had answered whether she was alive; what had followed her remained terrifyingly unknown.
