고대 바위에 꽂힌 룬 문자로 빛나는 전설의 검

A majestic and legendary sword, Excalibur, embedded in a stone or held aloft by a mysterious hand from a lake. The blade is gleaming, flawless steel with ancient runes etched near the hilt. The hilt is gold, wrapped in dark leather, with a large gemstone (emerald or ruby) in the pommel. The guard is ornate, with dragons or Celtic knotwork. Ethereal light glows from the blade, with magical mist or water droplets around it. Dramatic lighting, epic fantasy style, highly detailed, photorealistic.
