In 758 GUE King Mumberthrax commissioned his 17-year old son Frank Lloyd Flathead to design a new wing for the Castle. The breathtaking wing made Frank Lloyd the hottest architect in Quendor. Two years later the wing collapsed killing over 4000 royal guests. This was credited to a miscalculation by the stonemason, who was summarily executed. In the caverns near Egreth can be found the famous Glass Maze, Bozbarland, and the Great Underground Highway 2.
