A giant raven made of shadow particles and smoke, wings spanning entire city blocks, glowing red eyes piercing through darkness. Descends from the sky in total silence before exploding into thousands of smaller shadow birds that flood the streets like a living storm. Gothic city at night with heavy fog, rain and flickering lanterns. Begins with slow cinematic push-in toward the raven silhouette in the clouds, sudden crash zoom as wings spread, orbit shot through frozen rain droplets, FPV dive through the shadow swarm, volumetric smoke and particle simulation engulfing the frame, ending with all shadow birds reforming into the giant raven perched atop a cathedral while the city below disappears into darkness and the camera slowly retreats into the storm
