Caliburn: Golden Sword of the Victorious (勝利すべき黄金の剣
, Shōrisubeki Ōgon no Ken
?, also translated as Golden Sword of Assured Victory) is the holy sword that is the symbol of the king pulled from the stone of appointment by King Arthur under the guidance of Merlin. With the words "Whoso pulleth out this sword of this stone is rightwise king of all England" engraved in a golden inscription on its hilt, it became the symbol of England's King of Knights once it was pulled from the stone. It looks similar to Excalibur, which she later received from the Lady of the Lake, but it is a different sword and its characteristics as a Noble Phantasm also differ. It is not as strong of a sword as Excalibur as the swords of kings are often lowered to the role of fancy decorations due to being symbols of authority. The cost of being a dazzling sword is that its grade as a weapon is inferior to Excalibur. It was broken in a battle in which the rules of chivalry had been broken by Arthur, and she later received the new holy sword of the Lady of the Lake. Despite that, she has a stronger attachment to Caliburn.[3]

Merlin claimed that she would "no longer be human" after taking hold of it as a king is someone who kills everyone to protect everyone. Once she pulled it from the stone, the area filled with light, making her something inhuman and stopped her physical aging. Many knights thought it to be ominous while most praised their master's immortality as divine. After the sword was destroyed, Avalon later granted the same properties.

Originally, it was a sword for the sake of selecting the king. Its "Anti-Unit" classification does not refer to the enemy, but instead point to the one who shall have ownership over it from now on. When the owner turns into a proper, perfected king, its power will become appropriate for a holy sword.[1][2] Although inferior to Excalibur, this holy sword also converts the magical energy of the owner into heat values, releasing it as particles of light.[1] If this is employed in battle as a weapon, and its True Name is released, a firepower on the same scale as Excalibur will be displayed, but its blade will probably be unable to withstand Artoria's magical energy and break.[2]

  • Saber pulling the sword from the stone
  • Saber and Shirou using the projected Caliburn

Though it is a weapon forever lost that will never exist again, Shirou Emiya, upon seeing Saber's memories in his dreams, becomes able to project it during the Fate route. Due to having no real experience with projection, the weapon mostly uses the stored memories of Saber wielding it to attack and defend while merely pulling Shirou along. Despite being weaker than Excalibur, it is still a very strong sword capable of cutting through God Hand. Once used by Saber and Shirou at the same time, they are able to smash through Berserker's axe-sword, slash into his body, and release an attack of light similar to Excalibur from the inside that kills him seven times with a single attack. It is derived from swords with similar legends, such as Gram, "the sword of supremacy in the tree" from Northern Europe as Caliburn was the model for it, and Merodach, the original model of the "legends of the swords of selection in the various lands of the world" and "the foundation of the sacred right to select the king." If Caliburn were to face them, it would lose due to being a newer incarnation.
