There was little sense in attempting anything like subtlety, so I donned my bottle green spectacles, focused my supernatural senses, and began a slow survey of the entire place. The energy known as magic exists on a broad spectrum, much like light. Just as light can be split into its colors by a sufficient prism, magical energy can be more clearly distinguished by using the proper tools. The spectacles gave me a chance to view the energy swirling around the crowded room. It was strongly influenced by the presence of human emotion, and various colors had gathered around individuals according to their current humor.
