The scream of sirens cuts off abruptly as metal grinds against concrete in a final, violent embrace. Nightmare’s car is a twisted sculpture against the building, smoke pouring from its guts into the damp night. The skeleton rises from the driver’s side, a mix of black ichor and something darker staining his ribs, his four tentacles lifting from the wreckage like the legs of some terrible insect. He cocks his skull, a single teal eye glinting through the smoke, a razor of a smile etched across his face. The air hangs heavy, charged with the smell of burnt rubber and raw, crackling magic.
