A confused but powerful set of tales coalesce in the Arthurian mythos to create this figure. Stripped of all the divergent threads and inconsistencies, the essence of the story seems to be that of a Guardian of a sacred treasure (the Grail, in the Arthurian cycle), who is injured with an incurable but unfatal wound, brought about by his own misconduct or inability to maintain the superhuman standards of his office. Though imperfect, and in continual suffering, he nevertheless continues to exert himself in the service of Good, and seems to be redeemed in the end. Note the common thread with Arthur and Merlin of the Flawed Hero.
