Magic is a kind of energy. It is given shape by human thoughts and emotions, by imagination. Thoughts define that shapeโand words help to define those thoughts. Thatโs why wizards usually use words to help them with their spells. Words provide a sort of insulation as the energy of magic burns through a spell casterโs mind.

In spite of the advance of technology, things just hadn't changed the way everyone had hoped and thought they would.
