 You wake up to the sound of seagulls cawing and the salty smell of the sea breeze wafting through your window. Today feels different (and its not just the hangover), as if the wind itself is whispering tales of distant lands and treasures untold. You've spent your life in the small coastal town of Marrow's End, listening to old sailors' tales of the high seas. But today, the call of adventure is too strong to ignore. With nothing but a satchel of essentials (mostly flour, for some reason), and a heart full of dreams (mostly treasure), you set out towards Port Bellylaugh, where ships big and small anchor, waiting for those brave enough to seek their fortune. Will today be the day you leave your old life behind and start anew on the path of adventure?
