Excalibur is a legendary sword with a sleek, double-edged blade that tapers to a sharp point, featuring intricate engravings along its length that glow faintly with a mystical blue hue. The hilt is wrapped in dark leather for a secure grip, adorned with gold filigree and a large, oval-shaped pommel encrusted with a deep blue gemstone that pulses with energy. The crossguard is elegantly curved, resembling wings, and is made of polished silver with subtle weathering to hint at its ancient origins.
