Cinematic shot, Harry Potter and Hermione Granger (adults, fierce look) fighting back-to-back in a destroyed Diagon Alley. They are casting powerful spells with glowing wands (red and green light). Surrounded by terrifying mythical 'Shadow Stalkers' (smoke monsters with glowing eyes). Debris flying, fire, smoke, dark moody lighting, intense action scene, photorealistic, 8k, blockbuster movie style. Hermione holding Harry's hand while casting with the other.
