bo-an1me, dark fantasy illustration, high detail fantasy anime, A regal mermaid with iridescent scales shimmering in shades of turquoise and aquamarine, lounges on a gilded throne amidst the grandiose architecture of Atlantis, surrounded by schools of exotic fish darting through the translucent waters. Her slender, porcelain-skinned hand grasps a staff adorned with delicate sea anemones and glittering pearls, radiating soft, shimmering water magic that illuminates the aquatic environment. Her long, flowing locks of golden hair cascade down her back, with a few stray strands framing her heart-shaped face, accentuating her bright, piercing emerald green eyes. The atmosphere is tranquil, with soft, diffused light filtering through the water, casting an ethereal glow on the entire scene.
