The Fisher King ruled the Fisher Realm and protected the Holy Grail. During the quest he and his land have a connected sickness. This is cured only when Sir Percival, his son, arrives to take the crown from his father's sick head. At the end of the quest, it is speculated he dies.
During the quest, the Fisher King appears to be wearing an old model of the white chain body, though it has a pauldron added on the left arm. He is also wearing the old model for white platelegs. The gloves appear to be leather. It is unknown what type his staff is, though it may be a dramen staff as the Fisher Realm contains a fairy ring.
