I love writing magic-free fantasy that is set in a medieval-type era and is family-friendly. My family used to do a lot of read-alouds, and as I got older I realized that there were fewer and fewer books that I would feel comfortable reading to my younger siblings. I already loved storytelling, and I felt led to write stories that were safe enough for little ones while also being fun enough for the whole family. After several attempts and A LOT of prayer, the Arcrean Conquest series was born.
Most fantasy has magic, mysticism, and powers weaved into the fabric of the story. I’ve chosen not to include these “ingredients” in my own books. I addressed this topic a while back, during an interview with Future Homeschool Authors:
Why do you write non magical fantasy?
This question always makes laugh, because the answer is so very shameful :) I originally decided on fantasy because I didn't want to have to do research on accurate history/locations! I figured if I could make everything up on my own, writing would be so much easier. Boy, was I wrong. However, now that I know better, I do still enjoy the liberty that fantasy allows - I can make things up and it’s still ok.
As to the other half of the question, I write non-magical simply because I don't like magic and mysticism. I believe God is very clear in His Word about His opinion of witches/wizards, and His power is so much greater anyway. In short, I see it as a choice to have my characters rely on their own man-made strengths, or on the power of God (through prayer, faith, etc.). I prefer to strive for the latter.
If you feel the Lord directing you to write fantasy fiction, let me encourage you to prayerfully consider how God would have you to go about it. Always follow the Lord’s leading. He will never fail you!
