Caliburn, also known as Collbrande, is one of the Holy Relics and one of the four Holy Swords and is known as the Holy King Sword and the Sword in the Stone.


Caliburn is the Sword in the Stone that chooses the King in the legend of King Arthur. It is one of the three Holy Weapons wielded by the Legendary King of Britain, King Arthur Pendragon, of Camelot. The strongest Holy Sword, Caliburn, is one of the only Holy Swords to not be kept under the control of the Church or Heaven after the Great War, but by the Pendragon family. Caliburn is currently wielded by Arthur Pendragon, a descendant of the original King Arthur.


Caliburn has a grip long enough that appears as a two-handed sword with a round pommel at the end, and a long blade with a gold colored edge.


Caliburn is the most powerful Holy Sword in existence. It can generate a massive amount of Holy aura that surpasses even that of Courechouse and Durandal, and capable of ripping through space. In fact, it is powerful enough to be known as the Ultimate Holy Sword. It also has the power to manipulate space, able to teleport the user and others into any location, and as demonstrated by Uther, Caliburn can open small spatial portals to teleport its blade to strike enemies from any direction unexpectedly.


  • Caliburn is another name for Excalibur in Arthurian Legend and so has the exact same meaning.
