The Fisher King is a character that appears in The Lady of the Lake. There he is the human lover of certain sorceress Nimue. When Condwiramurs Tilly first arrives at the lake, she is taken to Nimue's island by the Fisher King and he does not leave a particularly favourable impression on her, but during her stay, she grows to appreciate him. Nimue also specifically forbids Condwiramurs from "taking advantage" of the Fisher King.
