An original magical girl heroine, the Ice Crystal Sage, stands at the center of a gigantic glowing pale-blue magic circle within a vast frozen cathedral, framed in a medium shot from a three-quarter low-angle view. She is a slender girl with long silver hair, cool sharp ice-blue eyes, wearing an elegant layered frost-white and pale-sapphire magical dress adorned with crystalline motifs. Her right hand is raised palm-up, fingers elegantly positioned, calmly cultivating concentrated magical energy swirling around her; glittering ice shards and luminous frost particles orbit her in graceful arcs, while faint crystalline fragments slowly drift upward from the glowing runes. The surrounding floor is intricately inscribed with intricate glowing snowflake runes and ice sigils radiating outward in a vast circle, with towering frost-covered stone pillars, soaring arches, and diffused streams of moonlight illuminating the scene. The color palette consists of silvery whites, pale blues, and soft moonlight golds, highlighted by icy glows and gentle lens flares, creating a tranquil yet commanding and mystical atmosphere.
