This is something I’ve been thinking about a lot lately, in part because of what I’m reading, not what I’m writing. (No, I’m not going to say what that is. The policy of this blog is not to name other writers or books unless I can do so in a positive way.)
When you write any type of speculative fiction (science fiction, fantasy, or horror), even if it’s urban fantasy or near-future science fiction, the writer is responsible for creating at least some aspects of the world in which the story takes place. If you write an urban fantasy about werewolves and vampires, it’s up to you to set up and then adhere to the rules by which those creatures operate. In second-world fantasy, of course, there’s a lot more world building–maps, political systems, history, all the details of daily life.
The important things are:
- You have to create a system that holds together. It has to make sense. People living on a plain devoid of trees can’t build wood houses and probably don’t eat fish on Fridays–or any other days.
- And you have to stick to the rules you create. You can’t go around making exceptions. (Now, that doesn’t mean that things can’t seem to be exceptions if your characters have an imperfect understanding of the rules. But somehow or other you’re going to have to let readers know that.)
These things are important to keep the readers immersed in the story. You, as a writer, have asked them to suspend disbelief. It then becomes your job to make sure you never make them sit back in their chairs and say “What?! That doesn’t make any sense.”
