The sky grows dark and ominous as storm clouds roll in. Like creeping celestial creatures, they stretch their silent fingers across the sky and pull their bodies forward to block out the stars. They are alive with color now, breathing purple, turquoise and gold, and their introductory silence is temporary. First comes a low rumble, then a flash of light. The storm clouds seem almost to smirk at each other as they complete their formation, preparing to release their fury into the sky - bright, booming and unstoppable. Then angry stinging bolts of lightning crack across the Heavens, unleashed by the creatures hanging above the earth in the black of night.
