Sunrise is usually convenient. You can see where you're going. The thing making noises outside the window becomes a branch. In The Curse of Dawn, daylight has a much less helpful job!
The book opens with this curse:
In the darkness of night, the moon is the only light. Your beauty will be as fair as your heart. But in the brightness of day, the sun enters the fray. You will be a nightmare, destined to be torn apart.
There is a useful little piece of machinery in those lines. The curse gives the reader a time to worry about before the story has explained how any of this happened.
Give the reader something to watch
Night and day are already familiar. Nobody needs a glossary to know that one will turn into the other. Put a threat on that change, and the reader has a way to anticipate trouble.
The opening does not provide an escape clause. It does not explain who can undo the curse or what that will cost. It gives us enough information to dread daylight while leaving the solution out of reach.
That is a useful distinction when writing a supernatural rule. A reader can understand the immediate danger without understanding the entire system. If the only information is that something terrible might happen at some point, there is very little to keep track of. A named condition gives the reader something specific to notice.
Let the wording do some of the work
The rhyme is doing a job here, too. “Night” and “light” sound comfortable together. By the time “day” arrives with “fray,” the same pattern has started making threats.
The form stays easy to follow. The promise gets worse.
You can use that in a fairytale without adding a page of explanation after the curse. Read the rule aloud. Can you remember the dangerous part after one pass? Can you point to the moment when it takes effect? If you need another paragraph to explain what the reader should fear, the rule may need a more concrete trigger.
Try it on one scene
Take a scene where a character is waiting for something bad to happen. Give that danger a condition the reader can recognize: a change in the light, a sound that stops, a door that has to stay shut.
Then look at the scene again. Which ordinary details would the character start checking? What would they do differently because the condition is getting closer? Keep the details that change their behavior. You do not have to decorate every surface with an omen.
For the exercise, leave the origin of the rule out of the scene. See whether the approaching consequence is clear without it. You can decide where the explanation belongs once the danger works.
