"Shimmer!" Stellar shouted to try to make her point. With the gunfire and the wash of noise rolling off of the approaching artifice of magic that was steadily approaching them, her voice was drowned out. The skin crawled and the stomach rebelled. Something about the magic was intrinsically foul, and it insulted their very being. Some of the weaker-willed city watch ponies broke down, running off out of the way of the seemingly unstoppable mass of magic. They, in their cowardice, proved to be the wiser, for when the spectral skull crashed into the line, it exploded. Pulsating waves of magical force threw ponies against walls, into the air, and tossed them across the stonework ground, leaving them in armoured heaps of pain in front of Thunder as he ran on, seeking an escape.
