Upon parting company with the ship and its crew, Tristran and Yvaine set off for Wall, and, after several adventures, encounter Madam Semele. Because of the witch-queen's curse, Madam Semele is unable to see Yvaine, but she agrees to transport Tristran the rest of the way to Wall, as she is on her way to the market herself. Tristran obtains a promise from Madam Semele that he will not be harmed, will receive board and lodging, and will arrive at Wall in the same manner and condition in which he departed. This promise, however, does not prevent her from transforming him into a dormouse for the duration of the journey. The star also rides on Madam Semele's wagon, unbeknownst to the old woman.
