Aurora Over a Clockwork City

A hyper-detailed 3D render of a night-time clockwork city beneath a sweeping aurora borealis. The metropolis is built from brass, copper, and dark iron, with interlocking gears of varying sizes, rivets, steam pipes, and ornate clock towers. Include glass domes, wind-up automatons wandering cobbled streets, and suspended gear-driven bridges. The aurora—greens, purples, and teals—shimmers across the sky, reflecting off polished metal, glass, and oil-slick streets. Cinematic lighting, volumetric fog, and realistic textures: brushed metal, engravings, and weathered grime in crevices. A high aerial perspective reveals a sprawling maze of cogwork blocks and towers, warm amber lamplight glowing below. Emphasize depth of field, global illumination, and subtle motion blur on rotating gears. The mood is wondrous steampunk fantasy with a dreamlike, otherworldly glow.
