Radulf was a wizard blacksmith who lived in the same village as Goodwin Kneen. After Gunhilda Kneen got a touch of dragon pox, Radulf was called in to play Catcher (Chaser) in a game of Kwidditch (Quidditch) against a team from Ilkley. During the game, he took a Blooder (Bludger) to the head when old Ugga failed to intercept it.
The name "Radulf" is derived from the Norse elements ráð meaning "counsel" and úlfr meaning "wolf".
