One of the great things about fantasy worlds is the multitude of ways in which magic is presented. As with any power, however, it’s only interesting as far as it is limited. Ned from Pushing Daisies can revive the dead with a touch, but only for sixty seconds; otherwise there are dire consequences. Fullmetal Alchemist’s alchemy centers on equivalent exchange, the idea that you must give something of equal value to obtain what you want. And in many universes, magic is only accessible through the use of physical magical tools.
