Enchanting Nighttime Cityscape Poster

Create a dramatic, dystopian cover for Shadows of Markovia: The Awakening. There is divided cities of Seraphex and Sunder are depicted—Seraphex gleaming with tall, metallic towers, neon lights, and an eerie, polished sterility, while Sunder appears dark, crumbling, and overgrown. Hovering above, incorporate a faint, intricate mark symbol, resembling a bio-digital circuit. Shadows and light interplay. It should be a mix of dark tones to give it a suspenseful feeling.
