The answer to this question depends on the story you are writing. A prologue comes before a story’s main content, while an epilogue comes after the story’s main content. Generally, the order is: Prologue, Main Content (Rising Action, Climax, Resolution), Epilogue.
If you’re considering using a Prologue and Epilogue in your story, here are a few points to keep in mind:
A Prologue introduces the characters and serves to draw readers in with a glimpse of what lies ahead. It can provide context for the main story or it can be completely separate.
An Epilogue often provides an update on how the characters are faring after the main events of the story. It can be a brief summary of the conclusion or it can provide some degree of closure.
Ultimately, it’s up to you how to structure your story. You may feel that a Prologue is better suited for your story or that an Epilogue is necessary for your themes to be fully developed. Here’s an article about Prologues and Epilogues that may provide additional insights:
