Northern Lights Fjord Nature Night Sky Exposure

Start from northern lights fjord nature night sky exposure as a complete visual prompt for a quiet fjord under green and violet northern lights. Prioritize still black water, steep mountain walls, and aurora ribbons, then build supporting atmosphere with small snow patches, star detail, soft reflection across the fjord. The camera direction should be clear: keep the fjord centered as a dark mirror beneath the moving sky. Use natural aurora glow with long exposure clarity, preserve real-world scale, and keep the final image mysterious, vast, and silent with aurora green, violet, and midnight blue color harmony. Avoid over-saturation, plastic textures, duplicate subjects, unreadable scale, and random text.
