appears in Pirates of the Caribbean: On Stranger Tides. According to the film's visual guide, this blade was forged in the lost city of Atlantis. The official Pirates of the Caribbean Online website implies that the sword was forged by the sea deity Triton himself and that it has passed from one ancient mariner to another. By the events of On Stranger Tides, the sword is in the possession of the notorious pirate Blackbeard, who uses it to control ships at sea. In the film, Blackbeard first used the sword to "hang" his mutinying crew with the rigging of the Queen Anne's Revenge. Blackbeard lost the sword after a duel with privateer Hector Barbossa, who wanted revenge on Blackbeard for attacking the Black Pearl (which cost Barbossa's right leg) prior to the events of the film. Barbossa claimed the sword before leaving Blackbeard to die at the Fountain of Youth. Climbing aboard the Revenge, Barbossa returned to piracy as he used the sword to sail the ship to Tortuga. In The Librarian, Excalibur, which appears in both the films and the television series, is shown as having been infused with magic by Merlin, giving it the ability to be summoned across vast distances and fight independently of its wielder. The sword primarily serves as a personal trainer and protector of the Library, working alongside Librarian Flynn Carsen, who gives it the nickname "Cal". In the first two episodes of The Librarians ("And The Crown of King Arthur" and "And The Sword In the Stone"), the sword is stolen by the Serpent Brotherhood, who use it to mortally wound Flynn. They then take it to the stone where it was originally forged, combining the two to steal Excalibur's magic and release it into the world. Flynn and his team manage to defeat the Brotherhood, but both he and Excalibur die of their injuries soon after. Cassandra, the Librarian responsible for these events, uses what little magic she can gather to heal them instead of herself. Excalibur makes a final appearance in the episode "And The Final Curtain", where Flynn's Guardian, Eve Baird, receives it from the Lady of the Lake. Flynn then uses it to destroy the staff of Prospero, who is subsequently erased from existence. In the fantasy adventure film The Bastard Sword, The titular weapon is a magical weapon similar to that of Excalibur but also has cursed properties
