Sir Percival was a knight of Camelot, and was part of King Arthur's Knights of the Round Table. While searching for a set of legendary artefacts called the "Golden Boots of Arkanesses," he was kidnapped by goblins in northern Asgarnia. He became their slave, and was thrust into a sack and forgotten for over a day. Percival is rescued during the Holy Grail quest and succeeds his father, The Fisher King, as new king of the Fisher Realm. It is not known what happens to the Fisher King, though it is implied that he passes away. After the quest, King Percival can be reached with fairy ring code bjr.
- His name is a reference to a knight named Percival from Arthurian legend.
- If you talk to Sir Percival after completing the quest in Goblin Village, you will ask "Aren't you supposed to be at the Grail Castle?", to which he will reply "You must have mistaken me with somebody else."
