Design a 3D terrain for the mystical planet "Start," featuring vibrant quartz crystals in colors like pink, blue, green, and purple, embedded across rocky surfaces. The crystals vary in size, glowing softly and casting colorful reflections that illuminate the ground. A dark, starry night sky enhances the magical atmosphere with shimmering lights. The terrain should feel otherworldly, blending vivid colors and gentle light to create an enchanting, alien landscape filled with hidden wonders.
