An Enchanted Anime Spider in a Grand Mansion Staircase

An ultra-detailed anime-style illustration of a large, intelligent spider perched on a grand staircase landing inside a sprawling Victorian mansion. The spider features a glossy black body with subtle crimson markings, iridescent legs, and bright anime-style eyes with luminous highlights. It wears a tiny jeweled pendant on its cephalothorax, giving it a regal, otherworldly appearance. The opulent foyer is filled with polished marble floors, gilded moldings, towering stained glass windows, heavy velvet drapes, and ornate chandeliers. Moonlight pours through the windows, while warm candlelight from wall sconces creates dramatic, long shadows on the floor. A wrought-iron railing spirals up the staircase, and delicate web strands glint between crystal chandeliers. The scene uses crisp cel-shading and painterly lighting typical of anime, with rich textures and a cinematic, mysterious mood. The camera viewpoint is a low-angle perspective from the marble floor, emphasizing the spider against the grandeur of the mansion.
