Aslan next appointed its first rulers, the cabby and his wife, as King Frank I and Queen Helen (the cabby's wife Nellie was called into Narnia by Aslan soon afterwards), and commanded them to rule peacefully over the talking beasts. Aware that the evil Witch-Queen Jadis had entered his new land, Aslan sent Digory to retrieve a magic apple from a garden in the Western Wild beyond Narnia. When Digory returned, the apple was planted by the river, where it immediately grew into a tree which as Aslan explained would protect Narnia from Jadis for many years.
