I’m writing a fantasy novel. Take that piece of information as you will. I’ve been worldbuilding as I go along, based around a central system of magic if you will, a reasonably original one I think (CAVEAT: I haven’t found anything in this particular vein yet anyway). Maybe I’ll tell you about it one day, or maybe you’ll get to read it.
I found these articles from Brandon Sanderson, author of the bloody awesome Mistborn series and “the chosen one”, the man who would finish the Wheel of Time epic by the late Robert Jordan. I’ve found them immensely useful.
