A mystical woman with flowing auburn hair reminiscent of Amy Adams is captivatingly portrayed. She cradles a luminous orb in her hands, reflecting the energies of a powerful lightning mage spell icon. Dressed in intricate garments, she wields a pentagram shield with the regal poise of a benevolent android necromancer. Her visage captures the essence of a high priestess tarot card and the ethereal beauty of an anime goddess. She embodies the spirit of the Celtic goddess Diana, her presence as enchanting as it is formidable. This breathtaking scene would be perfectly at home on CGSociety or ArtStation, where fantasy art reigns supreme.
