Boa was the daughter of King Claus, who is implied to be the last ruler of the Islands of Day. Until her death, Princess Boa is said to have been the Abarat's hope for concilation between Day and Night, the two warring factions of the Abarat. Shortly after this event, the Fantomaya transferred her soul into the unborn Candy, giving her immense magical abilities. She is said to have been very compassionate and inspiring of affection or devotion in people she met. She was set to marry Finnegan Hob when she was murdered on her wedding day by a dragon. The dragon that killed her was sent by Christopher Carrion, who was in love with (and rejected by) her.
