Years after Sapphira's battle against the Dark Plague, Princess Selene has grown up -- and so has her daughter, Terra. Despite her mother's numerous stories and the affirmation of her friends and people, Terra sees the world as a place that still welcomes darkness, and she wonders if the Dark Plague is really gone -- and if Pegasus was truly as real as her mother says. When tragedy strikes, Terra is faced with the haunting question of whether or not she can believe -- and whether it really matters in the end.
