Biffa (real name Enblith) is Hildy's best mate at the Gardale Lawschool in The Crown of Dalemark. She is huge with a very sweet face and personality, and is quite intelligent. She's a scholarship student, the daughter of the millers of Ansdale. She's the "surnam" of the Lawschool "grittling" team, which seems to be some kind of position of influence in that sport.
