When relief keeper Sarah Macleod arrives at the remote Flannan Isles lighthouse in December 1900, she discovers three keepers vanished without trace, their final log entries warning of something rising from the deep—but new entries continue to appear each night in the dead men's handwriting, growing more desperate as they beg her to keep the light burning before darkness claims her too.





A stark granite tower rising 75 feet above black cliffs on a treeless rock island, surrounded by violent Atlantic swells. The lamp room's prismatic lens casts rotating beams that slice through perpetual mist, while the keepers' quarters below reek of lamp oil, damp wool, and the omnipresent salt.

An unmapped oceanic chasm plunging beyond charted depths beneath the lighthouse foundation, where water takes on oily iridescence and physics behaves strangely. The darkness here is not mere absence of light but a presence itself, thick and aware.
Sarah Macleod's complete transformation from skeptical relief keeper to cosmic guardian, containing her arrival and discovery (Departure), her confrontation with the Presence and James Ducat's warnings (Initiation), and her ultimate choice to remain as watcher at the threshold (Return).
Sarah Macleod arrives at the Flannan Isles lighthouse, discovers the vanished keepers and impossible supernatural phenomena, confronts both James Ducat's ghostly warnings and the Presence from the abyssal depths, and ultimately transforms from rational skeptic into willing guardian who chooses to remain and watch the darkness.
Sarah Macleod arrives at The Flannan Isles Lighthouse and discovers the three keepers vanished without trace, beginning her investigation with rational skepticism that starts to crack when she finds the logbook.

Over several nights, Sarah experiences escalating supernatural manifestations as James Ducat's fragmenting consciousness tries to warn her and The Presence begins making its existence known through impossible physics and overlapping whispers.

As Captain Morrison's relief vessel approaches and the dark of the moon arrives, Sarah faces The Presence directly in The Abyssal Trench's influence and chooses to remain as guardian rather than flee, accepting terrible knowledge over comfortable ignorance.
