Prompt

Dramatic dark fantasy concept art of a solitary fire mage crossing a bridge of black glass within a vast volcanic caldera threaded by glowing rivers, the figure weighted to the right and facing into a broad diagonal sweep of lava and obsidian; crisp material rendering, charcoal-black, vermilion, and sulfur-yellow palette, intense underlighting from molten fissures, defiant and perilous atmosphere, controlled visual noise, no text, watermark, logo, border, UI, or interface elements.
