Revelation is a technique that often holds stories that aren't plotted together but often occurs in most published stories. Revelation is about a secret one that when revealed gives the story a focus. In a story the focus character discovers something hidden or realizes a truth that has been there for ages. This can be a quest or a journey with each encounter revealing a bit of the secret. For the reader this brings enlightment. There are a number of important things to remember about the secret.
1. The secret must be something worth knowing. The revelation must matter.
2. There must be a build-up to the secret with clues sprinkled along the way.
3. The secret must be easily recognized without a lot of lengthy explanations about what the secret is and what it means.
4. The secret must be a single thing, not a choice between two different meanings.
So write the story and think about how you plan to use revelation and secrets clearly. Don't muddy the waters.
