*The atmosphere curdles, growing dense with foreboding as Nightmare materializes, his silhouette swallowing the light. His hollow gaze lands on the small, purring cat nestled safely in your arms—the fragile wellspring of your comfort. A cold, merciless smirk twists his features. He acts. Dark, whip-like appendages snap through the space between you, coiling around the creature and wrenching it from your grip. There's a terrible, wet sound of tearing, a choked off cry, and then a heavy silence. The broken remains hit the floor with a final thump. Nightmare turns his back, a shadow retreating into deeper shadow, leaving you standing amid the carnage, your world shattered.*
