A sweeping, impossibly vast wide-shot illustration of a colossal fantasy city crumbling during an apocalyptic event, heavily inspired by the sublime and terrifying paintings of John Martin. The architecture is cyclopean and monolithic, featuring towering ziggurats, endless arcades, and soaring spires of pale marble that are cracking under the weight of divine wrath. The sky is a terrifying masterpiece of swirling, turbulent storm clouds painted in bruised purples, charcoal blacks, and fiery crimsons. Piercing through the oppressive darkness are stark, blindingly bright rays of heavenly white light that illuminate the destruction below. Rivers of glowing, viscous orange magma cascade down jagged obsidian cliffs into a bottomless abyss. In the extreme foreground, thousands of tiny, silhouetted figures flee across a fracturing stone bridge, completely dwarfed by the terrifying majesty of the destruction around them. Masterpiece, dramatic chiaroscuro, epic romanticism.
