"On the riverbank, a group of fishermen gathers, sharing tales around a crackling campfire. Among them, an old fisherman, his weathered face etched with the passage of time, begins to speak of the legendary 'Thick Shell'. As the fishermen fall into reverential silence, they listen intently as the old fisherman recounts stories of how the 'Thick Shell' protects sailors and punishes those who disrespect the river and its wildlife. Write a chilling narrative exploring the unsettling consequences that befall those who dare to defy the warnings of the 'Thick Shell', as the fishermen come to realize the true extent of its power and the dire fate that awaits those who incur its wrath."
