Narrators of the series include Nigel Planer and Tony Robinson, who many listeners will recognise from some of TV's greatest comedies. With many authors in the 70s and 80s trying to mimic the success of The Chronicles of Narnia and The Lord of the Rings, he began writing parodies that quickly became more popular than those they were poking fun at.
