Golden Age Fantasy Illustration Style, Painterly Realism, Crystalline Underwater Photography Aesthetic. A stunning view looking down through impossibly clear ocean water at a royal hunting party of Narnian Merpeople riding through ancient, seaweed-covered ruins on the seabed. The Crucial Riding Posture: The Merpeople are riding large, powerful, scaled hippocamps (mythical sea-horses). Crucially, the merfolk are perched securely in a distinct side-saddle position on the backs of their mounts. Their powerful, scaled fish tails are coiled elegantly around the side flank of the hippocampus for stability, rather than straddling them like a human. The Seahorse Anatomy: The hippocamps themselves have massive, armored tails that curl tightly forward beneath their own bodies, pushing them through the water. Key Figures & Details: The Mer-King, with flowing white hair and fierce eyes, sits side-saddle, holding a gold-tipped spear. His deep amethyst tail is visible coiled against the mount’s scales. A Mer-Queen rides beside him wearing a shimmering gown. Bright shafts of sunlight pierce the water, illuminating the specific details of their riding posture and glittering scales.
