HD-2D pixel-art background concept for a side-scrolling action RPG, one single 16:9 game scene, camera tilted about 30 degrees from above, clear walkable lower floor, crisp deliberate pixel clusters, restrained background contrast, no UI, no labels, no readable text. The hearth city is built inside an enormous dragon ribcage: brass, riveted iron, bone arches, layered market stalls, cool night sky between ribs. Scene: the furnace square at the moment allies reclaim the hearth, a small crimson-cloaked swordswoman and a few ally silhouettes defend the revived golden furnace light while the councilor in a dark formal coat retreats toward a narrow northern rift carrying a pale cold-ember spike; warm gold and cold blue meet, no battle gore.
