ปราการออบซิเดียนใต้สุริยุปราคาเพลิง

A dark epic fantasy vertical poster of an apocalyptic alien landscape beneath a blazing solar eclipse. Centered, symmetrical composition: a colossal black-and-gold eclipsed sun dominates the upper third, surrounded by a fiery orange corona, explosive radial flares, electric plasma tendrils, and glowing cosmic dust. Directly below in the midground stands a towering obsidian gothic cathedral with needle-thin spires and intricate filigree, emitting a faint green-gold interior glow; its central spire aligns precisely with the eclipse above. In the foreground and midground, thousands of tiny dark humanoid silhouettes march in a massive procession along three winding paths converging at the cathedral gates. The surrounding terrain is a desolate green-black wasteland of cracked plains, misty swamps, and jagged volcanic ridges under a cosmic sky filled with green nebulae and distant stars. High-contrast cinematic color palette of toxic emerald green, deep obsidian blacks, molten gold, and fiery orange with dense volumetric fog and glowing rim lighting. Painterly dark fantasy concept art style. At the bottom center, display exactly one text label reading "[GPT Image 2]" in clean, bold white sans-serif lettering. No other text, no borders, no modern structures.
