Synopsis
After many childless years, a king had a daughter so beautiful that he named her "Fairer-than-a-Fairy". This enraged the fairies, who resolved to kidnap her. They entrusted this to the oldest fairy, Lagrée, who had only one eye and one tooth left and could preserve those only by soaking them in a magical liquid at night. She kidnapped the seven-year-old princess, whose cat and dog followed her, and brought her to a castle, where she had a pretty room but was charged to never let a fire go out and to take care of two glass bottles.
