Third person narrators come in three different flavors
Third-person objective
The narrator only shares what they see, like a camera recording events. No thoughts or feelings. For example, "she ran through a forest."
Third-person limited
The narrator focuses on one character's thoughts and feelings. It's like peeking into their mind. For instance, "He wondered if he'd ever find the treasure."
Third-person omniscient
The all-knowing narrator reveals everyone's thoughts and feelings. It's like having backstage access. For example, "Little did they know, destiny was about to change everything."
