What does that mean for a storyteller? Fantasies deal in extreme opposites of place and person, from the mundane to the fantastical and back to the mundane again.

The first step in writing a good fantasy is to focus on the premise setup. Premise is the single most important element in any movie, but in fantasy it goes beyond high concept. Everything depends on how you set up the big opposites in the story.

The logic has to be impeccable, and it has to say what you want to say about living the good life. You can start negative, go positive and end negative, or you can start positive, go negative, and end positive.

But start with that basic sequence, and add all other elements of character, plot, structure, theme and dialogue within that strict frame.
