Demon Queen with Spiders in a Bioluminescent Cave

A sinister and malevolent demon queen, surrounded by a swarm of spiders. Her eyes glow with an eerie, otherworldly light, and her dark, tattered robes flow around her like shadows. The scene is set in a dark, foreboding cave, with the only light coming from the faint glow of bioluminescent fungi on the walls. The spiders are crawling all over her, their eyes gleaming with malevolence.
