An eerie, dimly lit chamber with opulent details, filled with ornate, dark wood furnishings and heavy, blood-red drapery. The central figure is a menacing demon with unsettlingly human features, its eyes glimmering with a malevolent intelligence. Its skin has a ghostly pallor, contrasted by its elegantly embroidered, golden-trimmed crimson robe. Sharp, twisted horns curl from its head, casting sinister shadows across the room. The background reveals rich tapestries depicting scenes of chaos and torment, and a glimmer of candlelight reflects off an intricately carved chandelier. In one hand, the demon holds a delicate, ancient book, its pages aglow with arcane symbols. The atmosphere is tense with an air of regal madness, blending the classical elegance of baroque style with the chilling presence of malevolence.
