The Lighthouse of Lost Shadows

In the humble town of Duskmire, nestled by the ocean bay adorned with cliffside houses and weathered fishing boats, stood sturdily an ancient lighthouse - a symbol of the town's identity. Named after its first keeper, Old Silas, it was called 'Silas's Beacon.' But to the locals, due to multitudes of strange tales passed down generation after generation, it was known as the 'Lighthouse of Lost Shadows.'
Embarking on her summer stay in Duskmire, young and curious Alicia had heard the whispers and decided to unravel the town's riddled secret. The light that emitted nightly from the lighthouse was not ordinary, as it seemed to transmute shadow into energy, absorbing every trace of darkness till only light remained. Shadows would simply disappear, only to reappear by the time sun made its daily gesture.
Alicia, a born investigator, decided to dedicate her summer to investigating the Lighthouse's enigma. She packed her equipment: an old digital camera, a notepad, multitudes of pens, and her scoffed-at baby blanket that still managed to warm her heart amidst her daring ventures.
She would go each day, attempt to capture pictures of the ephemeral shadows, scribble down notes, and sit in contemplation till the stars blanketed the sky with twinkling mysteries of their own. The lighthouse consumed the shadows, but its inner workings were shrouded in an impenetrable darkness.
Once, Alicia gathered the courage to confront the lighthouse keeper - an aged man named Chester. The wrinkles on his face folded into a story impossible to narrate. Smiling through closed lips, he allowed Alicia's inquisitions, purposefully elusive in his answers of 'child, some things are unexplainable,' or 'the beacon has its ways.'
As the summer days rolled into nights, Alicia discovered patterns in the shadow disappearances. The process was selective, it seemed; only certain shadows vanished, but they were consistent from day to day. A particular tree’s shadow vanished daily at sundown, but the one next to it remained untouched. This bizarre selectiveness piqued Alicia's curiosity further.
One day, she laid out marked pebbles and timed when their shadows disappeared in the lighthouse's green glimmer. Late that night, when the lighthouse had ceased its odd feeding, she was astounded. The order in which the shadows disappeared matched exactly with the numbers on the paper Chester had once handed to her, claiming, 'Old Silas’s forgotten cipher.'
Overwhelmed with newfound insight, risking herself, Alicia decided to confront the lighthouse once more. She stayed barricaded till midnight, when the sky was clear, and the moon cast a formidable shadow of the lighthouse. Adjusting her camera, Alicia captured the scene as the lighthouse started absorbing its own shadow.
It was then it occurred, an unprecedented event. The lighthouse flickered, choked like an old engine being restarted, and then an ethereal glow radiated from within. Shadowy figures manifested, with distinguishable features, and with an otherworldly beauty. They appeared to be the 'lost shadows,' innocent victims of the Lighthouse's unusual appetite.
Alicia's camera clicked repeatedly, capturing the spectral theatre. She stood frozen, watching figures dancing gracefully, acknowledging their existence before disappearing again, swallowed mercilessly by the fateful lighthouse. She waited with baited breath till the last shadow had left, leaving the lighthouse bathing only in the moonlight.
The morning sun brought about a different Duskmire. Alicia rushed to the town square, displaying the framed pictures of the spectral shadows. The townsfolk watched in amazement and disbelief, staring speechlessly at the nocturnal mysteries of their lighthouse.
The day held surprises for the lighthouse as well. It no longer cast or swallowed shadows. Its brilliant light had dimmed, leaving behind a faint but warm glow. Wonderment filled the air as all eyes turned to Alicia, finding in her a brave little heroine who had demystified the age-old tales of the Lighthouse of Lost Shadows.
