Mystical Twilight Sphere

A crystal sphere suspended in mid-air against a twilight sky. The sphere is clear with swirling mists inside, creating a mystical texture. The twilight sky is a gradient of deep blues and purples, with stars beginning to twinkle. The moon is visible, casting a soft glow through the sphere. Wispy clouds add to the dreamlike atmosphere. The ground below mirrors the celestial hues, enhancing the surreal effect.
