One feature shared by all Fantasy (or other) narratives predicated upon ‘magic’ is that the magic ‘has rules’. This is so because magical thinking ‘has rules’—psychological rules that is, which have exactly the same coherency and validity as, say, the ‘rule’ that ‘when turning on or off the light, I must flick the switch seven times or my family will die.’
I’d like to write a Fantasy novel in which the magic has no rules at all. That would be bracing. It might bring out this buried truth: million who think they love Fantasy because of the magic actually love it because of the rules.
