Celine is the daughter of King Jeffrey and Queen Daena , making her the princess of Castle __________ . Withdrawn and secretive, Celine is so low-key compared to the other royals that most people forget she exists… at least until King Jeffrey orders everyone to watch one of her dance recitals.

Little has been revealed of Celine's personality, though she seems unflappable and quirky. She spends most of her time either perfecting her dancing or spying on others, often reporting critical details to her mother. She's accompanied by a band of ninja, who, like Celine, are almost impossible to spot unless they wish to be spotted.
