Discworld & Narrative Causality

In Discworld, "stories are important" (Witches Abroad). They wrap themselves around people, play riddles with them, and shape their lives. A witch in a gingerbread house always has an unfortunate ending, a girl skipping through a forest in a red coat always meets. Nowhere is this more evident than in Witches Abroad, a tale of two powerful women fighting each other through stories. An evil queen forces people to obey the narrative, on threat of death.
