Art style: Cinematic Realistic.
A dark, eerie underwater cave filled with jagged rocks and glowing blue bioluminescent moss. A handsome silver-haired merman is chained to a large stone by thick, glowing black magical chains. Princess Aurelia is swimming cautiously toward him, her white scales illuminating the darkness. The atmosphere is tense and mysterious, with deep teal and indigo tones. Shot from a medium-wide angle.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
