Among them, an old fisherman, his weathered face etched with the passage of time, begins to speak of the legendary 'Thick Shell'. Even as the last embers die and the fishermen disperse, the presence of the 'Thick Shell' continues to be felt in the river's waters, a haunting reminder of the overwhelming power and sublime beauty of nature. Write a poignant narrative exploring the lingering sense of fear and unease that accompanies the memory of the 'Thick Shell', as whispers of its formidable presence linger in the minds of those who once gathered by the riverbank."
