<s>[INST] Here are the opening lines of the first chapter of a fantasy novel: 
"But as she stepped from the carriage and onto the rain-soaked cobblestones of Argent's Landing, Arin felt the familiar tug of unease settle into the pit of her stomach.

It was a town she'd never intended to set foot in, a place of whispered warnings and haunted memories.

Yet here she was, standing beneath the crooked sign that creaked in the wind like a dying sigh: 'Argent's Landing - Gateway to the Shadow Isles'."

How might I approach this character and setting to develop them further, especially in the first chapter of the novel?[/INST]
