Having run for nearly twelve years and over forty-five light novel volumes, the Toaru series has featured many different forms of magic, based on a wide variety of religions, mythologies, folklore, tales, occult concepts and other mystical whatnot. However there are many areas in these fields which haven't been featured yet or could be explored in greater detail.

My question is this:

Among the myriad of possible subjects which could serve as a base for magic, including mythologies, religions, folklore, occult concepts etc, which areas in particular would you like to be explored in the Toaru series in the future?
