Dumbledore invoque des runes lumineuses dans une salle de classe gothique

A breathtaking, ultra-detailed masterclass artwork set inside a majestic Gothic Hogwarts classroom. At the front, the venerable old Headmaster Dumbledore with long silver hair and starry wizard robes stands at the podium, casting glowing spell runes on a blackboard. Seated at carved wooden desks is an iconic audience of cinematic villains: Voldemort looking disdainful, Darth Vader squeezing into a desk with glowing chest panel lights, Heath Ledger's Joker playing with a glowing card, Thanos wearing the Infinity Gauntlet in the back row, and Hannibal Lecter sitting calmly. Floating candles illuminate the room with golden light, contrasting with cool blue moonlight streaming through stained-glass gothic arched windows. Volumetric dust motes, rich dark oak and stone textures, dramatic chiaroscuro lighting, masterclass cinematic composition, definition of High Visual Impact and Relevance to Theme, 8k resolution, masterpiece.
