The image depicts a monochromatic scene of a cloaked figure, possibly a sorcerer, standing before a swirling vortex in the sky. The vortex, rendered in shades of grey and white, dominates the upper half of the image and appears to pull in the dark clouds surrounding it. A city, shrouded in mist and smoke, stretches across the background, seemingly threatened by the celestial event. The figure faces the vortex, arms outstretched in a gesture that suggests control or summoning. Write a detailed description of the given image.
