Orabella is the niece of the Italian King and Queen and cousin of Princess Nicoletta, heir to the throne of Italy. She, her sister Noemi and Nicoletta became close friends with America Singer when they were invited for a party at Illéa. She made a briefly appearance during The Elite.
America described all the Italian ladies of the Royal Family who came to the palace for a visit as "statuesque". They were "tall, golden skinned, and absolutely beautiful", and they were "all so good-natured. It is like they carry the sun inside their souls and let it shine out on everything around them".
