Antiga rainha troll em trono de obsidiana em caverna luminosa

A towering, ancient troll queen with skin like gnarled oak bark and eyes that gleam with malevolent intelligence, sits upon a throne of obsidian in a cavernous underground realm. Phosphorescent fungi cast an eerie, otherworldly glow on her diamond-encrusted regalia and the grotesque skeletal minions that bow at her feet. The scene is rendered in a hyper-detailed dark fantasy style, reminiscent of classic haunting surrealism and along with grim, evocative character designs, with a palette of deep purples, sickly greens, and obsidian blacks, emphasizing a fantastical horror atmosphere.
