Now it is up to Magrat and her companions, Granny Weatherwax and Nanny Ogg, to ensure Emberella does not marry the Duc, despite the desires of another witch in Genua called Lilith, Desiderata's fairy godmother counterpart.
The trio of witches journey to Genua, which takes some time and involves numerous mis-adventures, such as an encounter with a village terrorised by a Vampire (where Nanny Ogg's cat Greebo catches it in bat form and eats it), an incident where they encounter a Running of the Bulls-like event, and a house falling on Nanny's head which she survives thanks to her hat with the willow reinforcement.
At that point, Emberella, Mrs. Gogol and Baron Saturday arrive at the ball, having broken the witches out of their prison with the aid of Cassanunda (a dwarf and the Disc's second greatest lover).
Her first command is to end the ball (she dislikes them) and attend the Mardi Gras parade, a form of binge-drinking carnival.
Granny manages to defeat Lily by trapping her in a mirror, unable to 'find herself', and the three witches return home.
