@MTKings Hello, as a reader for quite some years, I would like to share what I've observed to be standard in books, especially epic sagas. A few things I appreciate:
-Chapters (either named or numbered subjected to author's preference)
-Glossary for names and terminology of things in works of fiction/fantasy like for say a completely invented language. ;)
-Chronological bibliography to keep track of events
-Prologue is usually to introduce to a reader what to expect with intrigue, kind of like a blurb or sales pitch
-Epilogue is a post ending script to show resolve of the story
