Rondallsete, Rondolfsette, Rondolsett
A castle in the vicinity of Inglewood Forest where Arthur, Guinevere, and Arthur’s knights retired to dinner after an adventure at lake Wadling.
Galleron appeared and challenged any of Arthur’s knights to a duel to reclaim lands that Arthur had annexed.
Rondoles Hall was probably based on a real location; there are records of manors named Randalholme, Randasset, and Randerside in the area of Lake Wadling.
