Fan Casting The Raconteur's Commonplace Book: Series Adaptation

The rain hasn't stopped for a week, and the twelve guests of the Blue Vein Tavern are trapped by flooded roads and the rising Skidwrack River. Among them are a ship's captain, tattooed twins, a musician, and a young girl traveling on her own. To pass the time, they begin to tell stories - each a different type of folklore - that eventually reveal more about their own secrets than they intended. As the rain continues to pour down - an uncanny, unnatural amount of rain - it becomes clear that the entire city is in danger, and not just from the flood. But the guests have only their stories and one another. Will that be enough to save them?
