Thus begins a quest that leads Joey to the faerie land of Shei'rah, source of the music and home of the Old Ones, unicorns who are menaced by blindness. Indigo is a unicorn who has preferred to remain in our world in human form, but he helps Josephine to take her grandmother to Shei'rah and to cure the plague of blindness.
