Fiction depends for its life on place.
Writers describe the world they know.
Sights, sounds, colors, and textures are all vividly painted in words as an artist paints images on canvas. A writer imagines a story to be happening in a place that is rooted in his or her mind. The location of a story's actions, along with the time in which it occurs, is the setting. Setting is created by language. How many or how few details we learn is up to the author.
