A haunting female siren fused with a skeletal mermaid upper body emerging from dark abyssal waves (simple wavy base for stability). Pale cracked porcelain-like skin with deep black voids leaking ethereal purple mist, long flowing hair of inky tentacles and glowing bioluminescent strands, empty glowing eye sockets with tiny star-like pupils, sharp jagged teeth in a seductive yet terrifying grin, wearing remnants of a torn gothic veil that fades into shadows. Holding a cracked hourglass dripping liquid darkness. Pure dark fantasy horror-cute hybrid—mysterious, alluring, and impossible to ignore. Clickbait energy: "You NEED this siren skull on your shelf... one look and you're hooked forever!"
