Narrator.

The narrator is the character who tells the story within the literary work, while the author is the person who actually wrote the story.
An antistory is a work of fiction in which the narrator breaks the conventional rules of storytelling which challenges the reader's expectations.
When composing a work of fiction, the author may or may not mention him or herself, for example something like "I want to tell you about a strange experience I had..." and when an author does that, the author usually is not being autobiographical, but has invented a character to use as the narrator; this character is the authorial persona, which is to say, the identity being presented as the author.
