Morgana

Morgana was the fortune teller of the Psychic Circus. She also guarded the entrance of the circus tent. She tried to stop the Doctor and Ace from entering, since she knew that they would be in great danger. But when the Chief Clown appeared, she didn't dare to stop them.

The Chief Clown forced her and Ringmaster into two large wicker baskets. They both disappeared. (DW: The Greatest Show in the Galaxy)
