Is there anything specific when writing a fictional chronicle?

Among my experience with chronicles reading them. In the pro and or epilogue you have someone that sets up the story like a story teller for example in the Film Frankenstein(1931) Edward Von Sloan in the prologue set up the story and got you hooked at explaining it. Which in a chronicle you can technically write it like a regular fictional novel. Showing the events unfolding as if it were happening right then and there and the turn their world upside down in the epilogue or you could have a partial narrator or a monologue somewhere in the story
Hope this helps
