Gruffi burns the Great Book of Gummis and goes to Ursalia to find another to replace it. Their he meets Thornberry, a gummi who tries to save Ursalia from an evil witch, Lady Bane!!

Duke Igthorn meets Lady Bane for the first time and falls in love.

Gusto creates a lifelike stone statue of Zummi, then persuades Zummi to come to his workshop so he can create a better one. Meanwhile, Gruffi mistakes the statue for his friend, believing that Zummi has turned himself into stone - and so does Lady Bane.

Sunni finds an old enchanted Gummi quilt which records the old Gummis' greatest achievements on its patches. In her eagerness to show it to Calla, she loses the quilt to Lady Bane, who promptly employs its magic to try and make herself queen of Dunwyn.

Igthorn purchases a love potion from a traveling gypsy to get Lady Bane around. But a severe accident instead makes Lady Bane fall in love with Toadie, and Tummi in love with Lady Bane!

When Lady Bane gets a lock of Sunni's hair, she uses it as part of a spell to keep her eternally young. Unfortunately, the spell also ages Sunni from a young Gummi to an old Gummi.
