If you’re a writer working on your fantasy magic systems, I suggest that you decide what kind of feel you want for your magic. Do you like the techno-magic like you find in my books, or in books by . Modesitt Jr. and Melanie Rawn? Do you like the hybrids like you find in someone more like David Eddings or . Rowling? Or, do you prefer your magic to be more vague and mysterious, like you see in Tolkien or the George R. R. Martin books? I like to read works by all of these authors, but when I write, I prefer to have rules, costs, and laws to work with in my magic, and that makes it more fun for me.
