Inferno in the Subterranean Metropolis

A high-contrast comic-book illustration of fire raging through an underground city. A lone hero in a battered coat stands at the edge of a tunnel as flames flood a rail car and flare into the caverns. The city is carved from rock with glowing neon signs, bioluminescent fungus, and riveted metal walkways crisscrossing steam vents. Thick black ink outlines, bold flat color blocks, and halftone textures give a classic pulp vibe. Firelight dances on damp pipes, wet cobbles, and dripping stalactites; reflections shimmer in puddles as magma-like veins glow in oranges, reds, and electric blues. Dynamic low-angle perspective from behind the hero, with explosive fire bursts, smoke wisps, and speed lines to convey motion. Include details like subterranean rivers, scaffolding, trains, and distant drones; mood is pulpy, cinematic, and frenetic.
