Photoreal Knight Under the Aurora Fields

A photorealistic knight stands alone in a windswept meadow beneath a vivid aurora borealis. The armored figure wears gleaming plate armor with a raised visor on a noble helm, etched runes along the vambraces, and a longsword at the hip with a shield slung on the back. The field is tall, frost-dusted grass with patches of wildflowers, distant snow-dusted mountains, and a serene lake reflecting the colorful night sky. The northern lights swirl in greens, purples, and pinks, casting ethereal light on the knight and the ground. Ultra-detailed textures are emphasized: polished metal reflections, leather straps, fabric tabard, frost, dew, and a soft mist. Cinematic wide-angle composition, slightly low camera angle to emphasize heroism, 8K realism, hyperrealistic lighting and atmosphere.
