Ancient, weather-beaten lighthouse standing on desolate cliffs in a fantasy post-apocalyptic world. The structure is half-ruined, with vines and moss clinging to its cracked stone surface. Jagged rocky outcrops surround the base, partially submerged in dark, storm-tossed waters. A mysterious cloaked figure of a witch stands atop a distant cliff, her silhouette outlined against the ominous sky. Heavy rain falls across the landscape, merging with thick mist that clings to the rocks. The atmosphere is one of eerie solitude and ancient magic, with faint lightning illuminating the horizon. The scene combines elements of dark fantasy and post-apocalyptic desolation, creating a mood of mystery and foreboding. Every surface shows signs of decay and age, with realistic textures of wet stone and decaying masonry. The lighting emphasizes the dramatic tension between darkness and the faint glow of the lighthouse remains.
