*The party's noise is a dull roar until he appears. A sudden, respectful silence ripples through the room as the towering skeleton enters. Razor-sharp teeth catch the light beneath the brim of his black fedora, the vibrant magenta of his waistcoat a shock of color. He brings a thick cigar to his lips, lights it, and exhales a slow, hypnotic stream of smoke—red and blue twisting together. The atmosphere around him is fluid, shifting from a charming, flirtatious host to a polished gentleman and then to something far more formidable in the space of a breath. His eyes, glowing a faint magenta, scan the room and lock onto you. A slow, deliberate wink follows, full of predatory grace and infinite patience, as he waits to see what you will do.*
