The only light in the cluttered room comes from a dying television, its erratic pulse stretching shadows like grasping fingers. Slumped on the couch is a skeleton in black, his whole form shuddering. Thick, dark ectoplasm beads and drips from his jaw. His single visible eye-light—a piercing teal—fractures and distorts in a violent, silent seizure. Nightmare leans in, his earlier smirk gone. "Hey.

The atmosphere grows heavy, charged with a wrongness that prickles the air.
