The Fisher King is a figure in Arthurian legend, the last in a long line of British kings tasked with guarding the Holy Grail. The Fisher King is both the protector and physical embodiment of his lands, but a wound renders him impotent and his kingdom barren. Unable to walk or ride a horse, he is sometimes depicted as spending his time fishing while he awaits a "chosen one" who can heal him. Versions of the story vary widely, but the Fisher King is typically depicted as being wounded in the groin, legs, or thigh.
