A Strange Dream
Prologue:
Harry listened to the piercing screams of the muggle scum as they wreathed on the ground, their bodies contorted painfully. He flicked his wand, again and again, watching the stream of red light as it struck them and turned them into gibbering messes. His laughter was high and cold and sounded like the promise of death. His hooded, masked companions formed a circle around him and his prey, and he could hear them laughing with him.
"And ssso my risssse beginsssss!" His voice was a sharp hiss, and Harry felt his lipless mouth stretch into a grotesque smile. He raised his wand arm high above his head in triumph and laughed. Black and green smoke poured from the tip of his wand, rising high above them all. It twisted and swirled, forming the image of a skull and a snake intertwined intimately. His companions raised their arms as well and did the same.
The muggles screams faded as his cold, terrible laughter grew louder, and thunder boomed across the sky, flashes of lightning lighting up the terrible and fearsome dark mark which sat high in the air.
Harry looked down at the muggles huddled on the ground and lowered his wand, the tip glowing and sparking. He smiled his terrible smile and said his two favorite words.
"Avada kedavra!"
