I am planning a fantasy novel for NaNoWriMO, but I have come across a little road block. I haven't been able to come up with a unique magic system for it. The more I think about it, the more I think that the story will be okay without a magic system. But the problem I am finding is that in my favorite books the magic is one of the things that makes them so interesting and great. For instance the Furies in Jim Butcher's The Codex Alera, and the different magical abilities in Brandon Sanderson's The Way of Kings. Do you guys think that a fantasy novel can still be excellent without a magic system or not? And if any of you have read a fantasy novel without magic could you let me know the title and author so I can read it myself?
