An omniscient narrator is a storytelling technique where the narrator knows everything about the characters and events in a story. This type of narrator can provide insights into the thoughts, feelings, and motivations of multiple characters, offering a comprehensive view of the narrative. This perspective allows readers to understand the broader context and underlying themes of the story. Unlike a first-person or limited third-person narrator, an omniscient narrator is not a character in the story. Instead, they act as an all-knowing observer, guiding the reader through the plot and providing information that characters may not be aware of. This technique is commonly used in literature, such as in works by authors like Leo Tolstoy and J.K. Rowling.
