Ancient ruin city above a swirling cosmic abyss

A sprawling, forgotten city built by an ancient civilization, perched precariously on the edge of a cosmic abyss. Giant, cyclopean structures twist towards a sky filled with swirling, otherworldly nebulae. Strange symbols are etched into the ancient stone, hinting at forgotten rituals. Style: Cosmic horror, ancient civilizations, detailed matte painting, inspired by Zdzisław Beksiński and H.R. Giger, with a cinematic, foreboding atmosphere.
