You have books that contain three completely different magic systems, that they're little or no resemblance to anything I've seen before. Where do they come from?
This comes from my personal philosophy on the fantasy genre. I've been reading it for 20+ years now. I love the fantasy genre. But I personally feel that the genre hit some points in its career where it stagnated a little bit. It was not branching out as much as it should. And that was part of the drive behind me writing what I write. Now, I'm not pointing any fingers, it was just on us of the new generation to say, "All right, where can we take this genre?"
That's what happened in science fiction. If you go back, science fiction was one thing. And then the next generation made it something else. And then the next generation made it something else. It's why science fiction has such depth to it. And you can still find all the original stuff, and people are writing things like that right now, but you can also find this whole wide variety. And so the genre is extremely varied. And fantasy is a newer genre. It really is epic fantasy, really though. Fantasy goes all the way back. But epic fantasy was a genre that did not have enough of this variation to it, in my opinion.
The trick is that being really varied with your plots, you can do it, it just makes generally bad plot. You can do completely unexpected or completely depressing, you can do weird things with plot, but they're either confusing, or they aren't very fun to read. That's not to say nobody has ever done it, people do, but I really felt that fantasy, rather than plot, the place that it needed to innovate was in setting, and maybe in style. I really like how fantasy is kind of inching toward this... you see more gunpowder fantasies nowadays, you see more fantasies set in an African culture or an Asian culture, things like this. And this sort of expansion has really helped the genre quite a bit.
So, the magic systems, where do they come from? They're what I'm most excited about in the genre, so it's what I do naturally. Mostly, when I buy books and I read them, I'm like, "Come on. This same magic. Again? Can't we do something new?" So, it just happens naturally. I do want to say, at the end of the day, a generic magic system and a generic setting plus fantastic writing and characters is still better than the best setting you can imagine with boring characters. So, as writers, I would say to you, keep that in mind. You really need to learn to write killer characters and an engaging plot. But then, I suggest a lot of variety with the setting or the style, and ways that you can approach your writing.
