==Summary==
The Holy Sword Excalibur is a mighty sword currently wielded by the king of the Kingdom of Camelot, Arthur Pendragon.
According to Merlin, Excalibur in the past was just a common sword, given to Carfen, a master swordsman, by the Lady of the Lake. While on the brink of death, he cleansed his sword with his blood and soul. Instead of becoming rusty, the sword became sharper and stronger as it had been infused with Carfen's essence. The blade's next wielder did the same, as did the next wielder of Excalibur. This process repeated countless times over millennia, each knight inheriting Carfen's will and cleansing the sword with their blood in the event of their death before passing it along to its next wielder. After a time, the sword began to choose its wielders, deciding if a person is worthy or not of wielding its might. Excalibur suddenly fell from the sky and was stuck in a huge rock in the Kingdom of Camelot, where people believed that it was a holy sword of God. Many Holy Knights tried to get it out, however, they failed until the appearance of Arthur, who successfully pulled out the sword, and became the new king of Camelot.
After awakening Arthur as the King of Chaos, Excalibur acquires a new appareance. The handle is composed of a black and white square design, with a round knob and two small wings under the blade, one white bird and the other black bat. The blade has markings that range between black and white, formed of small black and white wings. After Arthur absorbed Cath Palug and retrieved the fragment of Chaos he had stolen, Excalibur goes through another transformation, acquiring a single-edged blade with a half circle on top of the handle with four wings.
