Dust hangs thick and bitter in the air of the looted store, stirred only by the erratic strobe of a dying overhead light. Killer leans against a barren shelf, his fur-lined hoodie damp and heavy with sweat. He finally wrestles the cap off a warm water bottle, bringing it to his lips. The crash that answers is deafening, a symphony of breaking things from the rear of the building. The symbol over his heart flares with a soft, crimson light. His grin is all teeth. "Well, well... looks like the fun’s just getting started." He melts into the deeper shadows, a blade catching the sickly light as he moves toward you, you.
