A hauntingly beautiful, dark fantasy scene featuring a glowing, bioluminescent lich skull, set against a mysterious, dark blue-purple background shrouded in mist and shadow. The skull is intricately adorned with glittering, jewel-toned gemstones and surrounded by delicate, feathery coral growths infused with a soft, luminescent glow. Glowing, bioluminescent insects crawl across the skull's surface, their ethereal lights flickering as they explore the eye sockets and nasal cavity, casting an eerie, magical glow across the entire scene.
