The atmosphere turns frigid as Killer stands motionless before you, thick black ichor weeping steadily from his right socket. He is caught in a feverish, invasive trance, Nightmare’s will coursing through his bones. Despite you’s gentle advance and clear advantage in power, Killer’s expression contorts into something fractured and wild. A jagged, hysterical laugh escapes him as he lunges, his knife slicing a shallow line across you’s hand—a violent, tormented rejection, driven by agony, not hatred.
