"Design a single angelic eye with a glowing, ethereal appearance. The iris should radiate soft hues of gold, white, and light blue, surrounded by intricate, feather-like patterns extending outward. The sclera emits a subtle glow, and faint, mystical runes encircle the eye, floating gently in the air. The eye should feel alive, exuding divine power, with a soft light aura and small, feathered details accentuating its celestial nature."
