Armored knight on misty mountain peak at sunset

"A majestic Eternal Knight standing atop a high mountain peak, overlooking a valley covered in thick mist at sunset, where golden and purple sunbeams pierce through the clouds. The knight is fully armored in shining silver plate armor reflecting the sky's colors, adorned with ancient engravings and mysterious symbols in turquoise and gold. He wears a closed helmet with delicate curved horns and a menacing faceplate, with eyes glowing with a faint blue light, suggesting an ancient power within. In his right hand, he holds a massive double-edged greatsword with a silvery-blue shimmering blade engraved with cosmic runes. In his left hand, he carries a large ornate shield featuring a phoenix symbol with outstretched wings, surrounded by a ring of sparkling stars and planets. A long, heavy silk cape in midnight blue, embroidered with gold and silver constellations, flows gently in the mountain wind. The background features a majestic range of mountains fading into the horizon, under a dramatic sky filled with colorful clouds and the first twinkling stars. Cinematic realistic style, ultra-detailed textures on the armor and cape, natural warm sunset lighting with deep shadows and strong highlights, magical fantasy atmosphere, 8k resolution."
