Excalibur is a legendary sword with a sleek, double-edged blade that tapers to a sharp point, featuring intricate engravings along its fuller that glow faintly with a mystical blue hue. The hilt is wrapped in dark leather, adorned with gold and silver filigree, and the pommel is set with a large, flawless sapphire that pulses with an inner light. The crossguard is elegantly curved, resembling wings, and is crafted from polished steel with subtle weathering to hint at its ancient origins.
