Fisherman

The Fisherman is a non-player character who inhabits the Fisher King Realm before the area is renewed. In The Holy Grail quest, the player must speak to him in order to enter the Fisher king's castle. The fisherman recommends that the player ring the bell outside the castle, at which point a bell item spawns to the north of the castle.

Later on during the quest, when the player returns to the area and Percival is now king, the area will be cleaned up and the Fisherman will have disappeared. It is unknown why, especially considering the area now has spots for Fishing.
