Blackwater Point Lighthouse was abandoned in 1989.
Thirty-five years later, it began broadcasting again.
When multiple ships report a lighthouse beacon rotating every thirteen seconds off a dead island in the North Atlantic, Division IV dispatches a recovery team to investigate what should have been an impossible malfunction.
Instead, they uncover something far older waiting beneath the ocean.
As the storm surrounding Blackwater Point worsens, the team descends into a drowned labyrinth hidden beneath the lighthouse — where missing crews, impossible signals, and a sleeping entity connected to the sea itself begin to converge.
Because the lighthouse was never warning ships away.
It was keeping something asleep.
DIVISION IV ARCHIVES: CASE FILE 07-THRESH is a dark cosmic horror novella blending analog horror, psychological dread, and classified archival storytelling into a chilling descent beneath the Atlantic.
