Create an ultra-stylish depiction of the back side of a tarot card with a slightly modern and unique twist. The design should feature abstract circular and spherical motifs, creating a harmonious and balanced pattern. Use intricate and elegant lines and shapes to form these motifs, enhancing the overall aesthetic. Incorporate elements of fantasy and mysticism, with swirling lines and ethereal textures that evoke a sense of wonder and enchantment. Use a color palette of deep, rich tones combined with soft, glowing highlights to amplify the fantastical atmosphere. Ensure the design is devoid of any human figures, focusing solely on the abstract and mystical elements. The overall aesthetic should exude sophistication, elegance, and an otherworldly charm, making the card back visually captivating and unique. --s 500 --c 10 --no person --niji 6
