Espada Excalibur en un Claro de Piedra de Bosque Nebuloso

Photorealistic image of King Arthur's sword Excalibur thrust into a mossy stone in a misty forest glade. The blade is immaculate, mirror-like steel reflecting dappled sunlight. Intricate Celtic runes glow with a soft blue light along the fuller. The crossguard is shaped like two dragons, their wings forming the guard, eyes set with emeralds. Cinematic lighting, volumetric mist, 8k, hyper-detailed.
