Fantasy
A prophecy only matters when it starts changing how people behave.
If everyone treats it like a decorative warning label, it’s just atmosphere with better fonts. The interesting bit is when the words begin to narrow the room around the characters. They hedge, they panic, they try to outwit the sentence already written for them, and suddenly the real question is whether destiny exists at all, or whether people are just making very expensive choices under pressure.
That’s usually where the story gets its teeth.

Prophecy is often less interesting as fate than as bad information. People start reorganising their lives around it, and half the damage comes from the rearranging. The prediction itself can be nonsense. The behaviour it provokes is where the story starts to leak.
