woman with long flowing electric blue hair and wisps of fiery orange around her face, holding a radiant crystal orb that illuminates a halo-like aura around her, grasping a silver pentagram shield with Celtic knotwork patterns, wearing an intricate golden circlet with small diamonds and a crescent moon charm, eyes closed in a serene yet powerful expression, surrounded by soft, ethereal lightning channels that dance upon her skin as if she is tuning into the cosmos, her slender fingers intertwined with the crystal orb as if channeling its energy, her high priestess-like robes flowing like a tattered cloak with hidden sparkles and whispers of rose gold embroidery, bearing an uncanny resemblance to a powerful witch from an ancient, mystical world, styled as if she just stepped out of a lavish fantasy realm, where serene goddess elements and technocratic necromancer elements blend seamlessly together.
