A Knight of the Round Table renowned for his purity and honor. Galahad is the illegitimate son of Sir Lancelot and King Pelles's daughter Lady Elaine of Corbenic. Sir Galahad is the only member of Arthur's corps who can sit in the Siege Perilous, a seat at the Round Table set aside by Merlin for the knight who would complete the quest for the Holy Grail. Galahad's quest for the Holy Grail, which he completed alongside Sir Percival and Sir Bors, ended when he encountered the Fisher King, who asked him to take the chalice to Sarras. Galahad is supposedly descended from the brother-in-law of Joseph of Arimathea, who later visits him and allows him to ascend to Heaven.
