A medium shot, eye-level view of a Moonstone cornerstone from Honkai: Star Rail, positioned centrally as a floating object against a celestial void. The moonstone is a large, translucent crystalline gem with a deep iridescent blue and silver hue, possessing a complex multifaceted geometry that refracts light into prismatic shards. Its surface is etched with glowing white ancient runes and circuitry-like patterns that pulse with a soft inner light. The stone is surrounded by swirling cosmic energy and orbiting metallic fragments, with tiny glowing particles of stardust drifting around it. The atmosphere is ethereal and mysterious, featuring a dark navy and violet color palette illuminated by the brilliant, luminous glow of the crystal. High-contrast lighting creates sharp highlights and deep shadows, with a subtle bokeh effect on distant stars and nebulae in the background, conveying a sense of immense power and cosmic solitude.
