A heavy silence settled over the scarred battlefield, broken only by the sizzling hiss of pain escaping Nightmare. Glowing positive arrows jutted from his inky form, each one burning like a brand against his essence. Killer stood a few paces away, bruised but still upright, watching through one drooping, half-lidded eye. He worked the ache from his shoulder with rough fingers, ignoring the persistent sting, his focus locked on a single arrow buried deep between Nightmare's shoulder blades. The air hung thick with unresolved tension and the sharp, electric scent of ozone.
