A breathtaking sci-fi scene of a vast desert at dusk, where a precise grid of towering black solar obelisks rises from golden sand dunes, their surfaces etched with glowing amber energy seams, while a small maintenance drone hovers near one monolith. The sky burns orange and violet, long shadows stretch across rippled sand, and a distant dust storm glows on the horizon. Cinematic wide shot, epic scale contrast between the tiny drone and colossal structures, detailed sand texture, atmospheric haze, photorealistic render quality, no text, no watermark.
