刻有符文並發光的傳說之劍插在古老岩石中

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.
