An alien world transformed into a shimmering amethyst paradise with sparkling amethyst crystals. Towering crystalline mountains, glowing caverns with gem- like stalactites, and a futuristic robot reflecting the purple glow. The sky swirls with auroras in purple, pink, and blue, as floating shards of amethyst hover. A radiant amethyst waterfall flows into a glowing landscape of crystal shards and moss- like purple luminescence, creating a magical, gem- world environment
