The opening narration in the first Conan story usually sets the tone for the whole series. It might introduce the main character, Conan, in a mysterious way, like highlighting his detective skills or the strange situation he is in.
One big limitation is that you only get one perspective. You don't know what other characters are thinking or doing unless the narrator finds out about it.
Omniscient. An omniscient narrator knows everything about the story, including the characters' innermost thoughts and feelings. It gives the author great flexibility. For instance, in 'War and Peace', Tolstoy uses an omniscient narrator to paint a vast picture of different characters from all walks of life during the Napoleonic era, jumping between their minds and showing a complex web of relationships.
The first chronological Conan story is 'The Phoenix on the Sword'. It was one of the early tales that introduced Conan as a character. In this story, Conan is already a king, ruling over a land filled with various challenges and mysteries. It gives us a glimpse into his character as a powerful and somewhat ruthless leader, while also setting the stage for the rich and fantastical world of Conan that would be further explored in subsequent stories.
The first published Conan story was 'The Phoenix on the Sword' which was published in 1932. It introduced the world to Conan, a character created by Robert E. Howard. Conan is a barbarian hero, and this story set the stage for many more adventures in the Hyborian Age.
