Narrative Causality

Any decent universe has the unseen but inferred element narrativium dictating how it should develop, and how any half-decent story should have a beginning, a middle, and an end.

A set of narrative laws dictate and clarify how this works. For instance:

-Any homely featured man who for whatever reason has to disguise himself as a woman will inevitably become attractive to some otherwise perfectly sane men, with, as the ancient scrolls say, hilarious results. (However, in the case of Gulli, Gulli and Beti, the laws were fighting against the fact of Nobby Nobbs, and gave up.)

Lilith de Tempscire knows all about the laws of narrative causality, and takes advantage of them to rule a state as the éminence grise behind the Duc's throne. The whole of Witches Abroad develops the theme of the eternally recurring story, and the weight of momentum that a good narrative carries as it seeks to roll all before it.

All urban legends are self-contained little nuggets of 100% pure Narrative Causality. The dead grandmother in the rolled blanket; the snake in the car that bites the driver while the non-driving passengers sit in mute paralysed fear, while the driverless vehicle crashes into the chemical tanker; the tarantula that laid its eggs in the ornamental cactus, which of course you put in the hottest driest part of the house (perfect incubating conditions for a thousand baby spiders, all of which are venomous from the egg)... all these little gems have potent narrative force and may be acting themselves out, even now, in a universe near you.
