When Fairer-than-a-Fairy is twelve, her beauty becomes famous in all the surrounding countries. The Fairies become jealous of her beauty and her name and decide to avenge themselves and destroy the Princess  beauty. The Queen of the Fairies, named Nabote, goes to the castle in order to kidnap Fairer-than-a-Fairy but she finds it impossible, because the wizard who built it put a spell so that its inhabitants could neither go out unwillingly, nor be bewitched.
Nabote goes into the castle as a servant and makes friends with Fairer-than-a-Fairy. One day, she opens a door that gives onto the countryside and pretends to faint outside the castle s walls. Fairer-than-a-Fairy runs to her but no sooner has she gone out that Nabote seizes her and takes her to her Kingdom.

When the Fairies find that the two princesses have fulfilled the tasks, they order Fairer-than-a-Fairy to go on Mount Adventurous and fill a vase with the Water of Immortal Life. They give her feathers and wax, hoping she will crash like Icarus. D sirs is sent on the beach and ordered to write something on the sand on condition that it will not fade.
