Ancien autel de cristal sous un ciel de nébuleuse cosmique tourbillonnante

A breathtaking, wide-angle shot of a majestic, ancient altar made of enormous, glowing amethyst and quartz crystal shards, reaching towards a swirling, vibrant nebula sky. The altar is situated on a desolate, otherworldly plain, illuminated by the cosmic light filtering through the crystals, casting long, geometric shadows. Wisps of ethereal energy rise from the altar's surface. The colors are dominated by deep purples, blues, and electric pinks from the nebula. Epic fantasy, cosmic, crystals, ethereal, majestic, vast, detailed, dramatic light.
