The Queen of Ambrosia is a mythical character mentioned in Professor Layton and the Eternal Diva. She is portrayed by Janice Quatlane in an opera. It is said that the people of Ambrosia loved her very much. One day however, she got very ill and was about to die. The people raced to find a cure in order to save her life. But the cure came too late, as the queen had already died. Out of great sadness, all the people of Ambrosia took the medicine themselves, so that they could wait forever for their queen to return one day.
