An ominous demon god shadow looms across the vast universe

Dark fantasy book cover scene, Xianxia style. An ominous gigantic shadow of a demon god looming over the entire universe. A lone male warrior in dark robes stands on a cliff edge, facing a massive swirling cosmic vortex that is consuming solar systems, planets, and celestial palaces. Vibrant dark purple and neon red energy arcs crackling across the scene. Intricate Chinese fantasy landscape elements mixed with chaotic dark magic. Epic scale, dark atmosphere, highly detailed digital illustration, intense cinematic lighting, high contrast, clean book cover background, strictly no text, no words, masterpiece.
