In literature, an omniscient narrator is a narrator who appears to know everything about the story being told, including what all the characters are thinking. Stories told by an omniscient narrator are usually narrated in the third person; in other words, no character is referred to as "I" or "you" except in dialogue. In some unusual cases, the reliability and impartiality of the narrator may be in question. An omniscient narrator offers the reader a bird-eye view about the story.
