Cirilla Fiona Elen Riannon, born in 1251, heiress to the throne of Cintra, Princess of Brugge and Duchess of Sodden, heiress to Inis Ard Skellig and Inis An Skellig and Suzerain of Attre and Abb Yarra. Daughter of Pavetta (see Pavetta Fiona Elen) and the Urcheon of Erlenwald (see Emhyr var Emreis). Granddaughter of the famous Lioness of Cintra, Queen Calanthe (see Calanthe Fiona Riannon).
A shipwreck occurred during a journey from Cintra to Skellige which took the lives of the Urcheon and Pavetta. Cirilla's further upbringing was then entrusted to her grandmother. In 1260, afraid of the looming Nilfgaardian threat, Queen Calanthe sent Cirilla to the court of King Ervyll (see Ervyll of Verden), where the heiress of Cintra was to marry the heir to the throne of Verden, Prince Kistrin (see Kistrin of Verden). Though allying with Verden and gaining the aid of that realm's army was at the time Calanthe's top priority, no marriage ever occurred, and Cirilla returned to her grandmother's court. In 1262, during the so-called Cintra Massacre, Cirilla went missing (...).
