Excalibur is a legendary sword with a sleek, double-edged blade that tapers to a sharp point, featuring a subtle wave pattern along its length reminiscent of flowing water. The blade is crafted from a mysterious, gleaming metal that appears almost luminous under sunlight, with a faint blue hue. The hilt is ornate, wrapped in dark leather for grip, with a crossguard shaped like two dragons facing away from each other, their wings forming the guard. The pommel is a polished, deep blue gemstone set in intricate silver filigree, symbolizing the sword's mythical origins and power.
