artist: , A medium shot, slightly low angle depicts an original magical girl called Abyssal Starlight Sage, centered within a vast cosmic cathedral-space. The mage is a highly intellectual girl with long, deep purple hair cascading past her waist and eye-level bangs framing her wide, mysterious glowing violet eyes. Her skin is pale. She wears an elegant layered gown of midnight purple and starlit silver, featuring intricate cosmic embroidery and flared sleeves, reflecting soft light from the surrounding magic circle. Her posture is calm and regal as she holds her luminous staff firmly in her right hand, letting its radiant glow highlight the delicate contours of her costume. Floating arcane glyphs and glittering lavender star fragments orbit her in slow, deliberate arcs, echoing the massive glowing silver and violet magic circle beneath her feet inscribed with constellation runes and shifting time sigils. The surrounding environment is a high-ceilinged, cathedral-like void of deep indigo darkness, where starlit archways and nebulae stretch upward. Soft, ethereal violet and silver lighting illuminates the scene, with starlight particles drifting through the air and a gentle bokeh effect, creating a mysterious, contemplative atmosphere.
