The third-person omniscient point of view is a traditional voice used in writing that enables the narrator to be fully objective. It enables omnipotence, because it locates the narrator outside of the situation. Instead of every event and occurrence being interpreted through the eyes of one character, the events and occurrences are narrated to the reader through an objective source.
Multiple Characters' POVs
One of the major advantages of third-person omniscient point of view is the ability for the narrator to move about the plot of the story freely so they are not trapped in one character's point of view. This allows the narrator to give the readers multiple viewpoints throughout the story to keep it interesting. It also gives the writer great freedom by being able to competently express the feelings of others without having to somehow include it in the plot.
Another advantage of writing stories in the third-person omniscient point of view is that the author's voice has no limits in the use of language. When authors write in the first-person point of view, the use of language is severely restricted as is the slant on the plot of the story being told. This is because when writing in the first person, the narration must "fit" with how that character would act and speak.
The third-person omniscient point of view also allows the author to write plenty of action into the plot of the story. There is an ability to freely use descriptive language throughout the story so the author can paint a vivid picture as to what is happening to the characters. This in turn makes for a more interesting story for the reader. In third-person narrative, certain events can unfold while the main character remains completely unaware, thus adding to the suspense of the story. The writer can also add details that the main character would not (or could not) have noticed or realized from his point of view.
