According to Wikipedia,
An epilogue is the final chapter at the end of a story that often serves to reveal the fates of the characters. Some epilogues may feature scenes only tangentially related to the subject of the story. They can be used to hint at a sequel or wrap up all the loose ends. They can occur at a significant period of time after the main plot has ended. In some cases, the epilogue is used to allow the main character a chance to "speak freely".
Now, my understanding is that in most cases the epilogue is at most one chapter.
Yet, if you have multiple characters in your story, you may want to "wrap loose ends" for each one of them. This is especially true if your narrator has a limited perspective of the events, and wouldn't be able to talk of all the relevant characters in a single chapter.
So, can you write more than one epilogue?
Of course, I'm well aware that you can put how many chapters you wish at the end of your novel. What I'm interested in is if it would be possible to "extend" the notion of epilogue to a subset of chapters.
E.g, if we have three characters, Alice, Bob and Charlie, we may want to have:
- Epilogue: Alice
- Epilogue: Bob
- Epilogue: Charlie
Each one keeps the basic functions of an epilogue described above.
