Thomas Carter stood at the edge of the cliff, the wind tugging at his coat as he gazed up at the towering structure. "A new beginning," he murmured to himself, hoping the solitude would offer him peace. The lighthouse, with its peeling paint and weathered stones, seemed to promise solace.

Thomas explored the rooms, his footsteps echoing in the silence. It was then he noticed a small, battered notebook lying on a dusty table. He opened it to find scrawled handwriting, pages filled with warnings and cryptic notes. "Beware the depths," he read aloud, a chill creeping up his spine.

Thomas couldn't shake the feeling of being watched. He sat by the window, the notebook in his lap, listening to the wind howl. "Why would someone leave warnings?" he pondered, the words echoing in his mind like a sinister lullaby.

Determined, Thomas delved deeper into the notebook. It spoke of Eli, the previous keeper, and a presence that lurked below the lighthouse. "It was built to keep something in," he read, realization dawning on him.

Each step echoed ominously, the light from his lantern flickering with each breath of wind that seeped through the stones. "What did you hide, Eli?" he whispered into the gloom, his voice swallowed by the darkness.

Thomas hesitated, his hand hovering above the latch. The words from the notebook echoed in his mind, but curiosity drove him forward. As the door creaked open, he felt a rush of cold air and the sensation of eyes watching from the shadows. "Let the light guide you," he recited from Eli's notes, stepping into the unknown.
